Ordaz v. Hurst

2026-08-20

Summary

Holding. The appellate court affirmed the circuit court's judgment, holding that the circuit court did not abuse its discretion in barring the late-disclosed expert testimony as a discovery sanction and that summary judgment was properly entered because the plaintiff failed to present sufficient evidence of proximate causation in her medical negligence claim.

Deana Ordaz, acting as special administrator of her deceased son's estate, sued Dr. Daniel Hurst and his medical imaging company for negligent radiology services that allegedly caused her son's death. Hurst interpreted X-rays taken at an emergency room and concluded there was no acute disease, when the images actually showed signs of an aortic aneurysm. Two days later, the decedent died from a ruptured dissecting aortic aneurysm. Plaintiff missed court deadlines for disclosing two expert witnesses—a radiologist and a cardiothoracic surgeon—on multiple occasions over several months, prompting the circuit court to bar their late-disclosed testimony. The trial court then granted summary judgment for the defendants, finding that without expert testimony on whether surgery would have been performed and likely successful, the plaintiff could not prove proximate causation.

Plaintiff appealed both the exclusion of her experts and the summary judgment. She argued the preclusion was too harsh a sanction and that the remaining expert testimony from other physicians could establish her case. The appellate court examined six factors used to evaluate discovery sanctions and concluded the circuit court did not abuse its discretion in enforcing its scheduling orders. The court noted that deadlines serve an important function in case management, the plaintiff showed a pattern of noncompliance without seeking extensions, and the defendants acted diligently in pursuing discovery. The appellate court also examined the available expert testimony and found it insufficient to create a genuine factual dispute on proximate cause, as the remaining witnesses either lacked the necessary surgical expertise or offered only speculative, anecdotal opinions.

Key issues

  • Whether barring expert testimony for failure to meet discovery deadlines constitutes an abuse of discretion
  • Whether a discovery sanction for missed deadlines qualifies as punishment versus enforcement of court orders
  • Whether expert testimony from non-surgical specialists suffices to establish proximate cause in medical negligence when the defendant's expert is precluded

Procedural posture

This is an appeal from a circuit court order granting a motion to bar expert testimony and a subsequent grant of summary judgment in a medical negligence wrongful death action.

OPINION

¶1 Plaintiff Deana Ordaz, the mother of decedent Noah Ordaz and special

administrator of his estate, brought wrongful death claims against defendants Daniel Hurst, D.O.,

and his employer, Specialists in Medical Imaging, S.C., alleging that Hurst provided negligent

medical treatment to decedent. During discovery, plaintiff twice failed to abide by the deadline for

disclosing expert witnesses and their opinions. This ultimately resulted in the circuit court granting

defendants’ motion to bar the late-disclosed expert testimony and denying plaintiff’s motion to

reconsider. The court subsequently granted defendants’ motion for summary judgment, reasoning

that plaintiff would be unable to prove the proximate cause element of her claims without expert

testimony on that issue. She now appeals, arguing both that the preclusion of her experts’ testimony

was an abuse of discretion and the granting of defendants’ motion for summary judgment was erroneous. We affirm the circuit court’s judgment.

¶2 I. BACKGROUND

¶3 A. Decedent’s Death

¶4 The record developed in connection with the motion for summary judgment reflects

the following. On March 25, 2017, decedent awakened with sudden-onset chest pain. He went to

the Proctor Hospital emergency department in Peoria, Illinois, where he was seen by James Brown,

M.D., an emergency medicine physician. Decedent complained of left-sided substernal chest pain,

which he characterized as a 7 on a scale of 1 to 10. Brown’s differential diagnosis included

pneumonia, myocarditis, and pericarditis, and he ordered chest X-rays.

¶5 Defendant Hurst, a radiologist, then read and interpreted the results of the X-rays.

He concluded “there is no evidence of acute disease in the chest.” Brown relied upon Hurst’s

impression in his treatment of decedent. He discharged decedent with a diagnosis of chest pain of

an unspecified type.

¶6 That night, decedent told his family that his pain was feeling much better. Two days

later, one of decedent’s family members heard a thud coming from behind the locked door of

decedent’s bedroom. First responders arrived at the house and pronounced decedent dead. A

pathologist’s report concluded that he died due to a hemopericardium associated with a ruptured

dissecting aortic aneurysm.

¶7 B. Plaintiff’s Initial Investigation and This Action

¶8 In March 2019, diagnostic and interventional radiologist Myron Marx, M.D.,

conducted his own review of decedent’s chest X-rays and autopsy. He ultimately disagreed with

defendant Hurst’s interpretation, writing as follows in a letter to plaintiff’s counsel:

“There is clear evidence of abnormal density in the retro sternal clear space on the

-2-lateral film. The differential diagnosis of a mass in this region includes lymphoma,

teratoma, ascending aortic aneurysm, thymoma and retrosternal thyroid mass. The

diagnosis of an aneurysm of the ascending aorta is supported by poor definition of

the aortic knob on the frontal film, increased soft tissue density cephalic to the aortic

knob and clearly defined density outlining the anterior proximal ascending aorta on

the lateral radiograph.

To have met standard of care, the interpreting physician needed to make

note of the mass and recommend further imaging studies, specifically a contrast

enhanced chest [computed tomography (CT)]. The failure to have made this

observation and recommendation resulted in this aneurysm/dissection going

untreated until it ruptured into the pericardial sac resulting in the patient’s death

two days later.”

¶9 Plaintiff filed this wrongful death action in March 2019. Count I asserted a claim

of medical negligence against Hurst, and count II asserted a respondeat superior claim against his

employer, Specialists in Medical Imaging, S.C. Plaintiff brought claims against other hospital

entities as well, but they were voluntarily dismissed.

¶ 10 C. Discovery

¶ 11 In August 2019, the circuit court issued its first case management conference order

regarding discovery. It imposed no deadlines for discovery but set a subsequent case management

conference for December of that year.

¶ 12 The deposition of Brown, the emergency room doctor, was taken in November

2019. Regarding his expertise, the following exchange occurred during the deposition:

“Q. Based on what you know of Noah passing just a couple days after this,

-3-do you believe that he had an aortic dissection at the time he was in the emergency

room on March 25, 2017?

A. I can’t formulate that opinion.

Q. Is that based on history, information or specialty that you’re not able to

formulate the opinion?

A. I think all of those things.”

Brown further testified that, if he had diagnosed decedent with an aortic dissection, he would have

placed an “[i]mmediate call to [a] cardiothoracic surgeon.” When asked if, in the past, he had

diagnosed an aortic dissection and had a cardiothoracic surgeon “fly in there and perform surgery

on the patient,” he answered in the affirmative. In those instances, he indicated that he “believes”

the patient survived and that “in my 20-plus year career that maybe I have had it five times and

they have all been adults or if there was a younger person with significant risk factors for that.”

¶ 13 In May 2020, defendants filed a motion to compel discovery responses on the basis

that discovery requests served in July 2019 had not yet been responded to. The record does not

clarify what came of this motion. Over six months later, in January 2021, plaintiff provided her

initial disclosures, listing, in pertinent part, Brown as an independent expert witness, Hurst as an

adverse fact witness, and Marx as a controlled expert witness, pursuant to Illinois Supreme Court

Rule 213(f)(2), (1), (3) (eff. Jan. 1, 2018), respectively. Plaintiff disclosed anticipated testimony

from Hurst and Marx concerning the applicable standard of care. The disclosure listed only Marx

as having opinions about “the cause, proximate or otherwise, in bringing about the harm suffered

by decedent,” stating more specifically that the alleged negligence “resulted in the death of the

decedent” and deprived him of a “chance to survive or recover.” Plaintiff’s disclosures included a

copy of Marx’s March 2019 letter to plaintiff’s counsel. The letter focused on the standard of care

-4-related to the care provided by Hurst; it made no mention of the treatment decedent would have

received, such as cardiothoracic surgery, had a proper diagnosis been made.

¶ 14 Defendant Hurst’s deposition was taken in November 2021. He testified about the

radiological standard of care, indicating that a CT scan with contrast is the “gold standard” for

diagnosis of an aortic aneurysm, with a probable accuracy rate of higher than 95%. However, he

had no opinion as to if or when cardiothoracic surgery would have occurred or if it would have

been successful. When asked whether he was “going to offer any opinions regarding standards of

care or medical opinions in the area of cardiology” or “cardiothoracic surgery or cardiothoracic

opinions” in this case, he said he would not unless they specifically pertained to radiology.

¶ 15 In August, the circuit court entered a case management conference order setting a

November 14, 2022, trial date. No other deadlines were set in the order.

¶ 16 An e-mail chain from April 20, 2022, shows the parties appeared to be working on

scheduling the deposition of Marx. An April 28 letter from plaintiff’s counsel states, “[t]here will

be a more detailed disclosure, I’m hoping to get that to you shortly.” A July 25 letter from defense

counsel to plaintiff’s counsel stated that the supplemental disclosures had still not been received,

despite repeated requests. The letter also indicated in relevant part that they were running out of

time to complete expert discovery by the trial date, so it should be vacated by an agreed scheduling

order setting disclosure and deposition deadlines.

¶ 17 In an order entered in late September 2022, the circuit court struck the trial date by

agreement of the parties and ordered plaintiff to file her supplemental expert report within 45 days.

The court set a December 2 case management conference “for status on expert discovery and trial

setting.”

¶ 18 When the parties returned for the December 2 status date, plaintiff had not complied

-5-with the prior order requiring expert supplementation within 45 days. No transcription of the

December 2 hearing is contained in the record, but the circuit court issued an order at that hearing

providing as follows: “Plaintiff to supplement expert disclosures by no later than 12/30/22.” The

court set January 27, 2023, as the next case management conference date.

¶ 19 It is undisputed that plaintiff did not supplement her expert disclosures by the

extended deadline of December 30, 2022. She also did not request an extension prior to expiration

of the deadline.

¶ 20 The record does not reflect what was discussed at the case management conference

of January 27, 2023. On February 2, plaintiff’s counsel left a voicemail for defense counsel

indicating that plaintiff needed a few more days to complete the supplemental disclosure of Marx.

The voicemail also mentioned for the first time that plaintiff was planning to disclose a

cardiothoracic surgeon as an expert and that his report would be served shortly.

¶ 21 D. Motion to Bar

¶ 22 On February 10, 2023, defendants filed a motion to bar plaintiff’s supplemental

Rule 213(f)(3) disclosure. The same day, plaintiff filed her supplemental expert disclosure

regarding Marx; this disclosure did not purport to name any new experts. However, on February

17, plaintiff disclosed Carl Adams, M.D., a cardiothoracic surgeon, as a controlled expert witness.

Later that month, defendants served discovery requests for production of documents related to

Marx and Adams. In March, defendants filed an amended motion to bar the supplemental

disclosures of plaintiff to account for the new disclosures. In April, plaintiff provided defendants

with deposition dates for Adams in May and June and for Marx in June and July. She also filed

her response to the motion to bar.

¶ 23 On April 20, plaintiff delivered her responses to defendants’ request for production

-6-regarding Adams. The same day, the hearing on the motion to bar took place. Among various

arguments, defense counsel argued that defendants were prejudiced because the delayed trial date

resulted in a larger prejudgment interest amount and because the pending litigation is bad for the

doctors as they reapply for insurance. Plaintiff argued that defense counsel failed to address the

test that applies when a circuit court is considering a motion to bar. She also argued that

“Dr. Marx is going to render the opinions of standard of care. Dr. Adams is going

to kind of fill in the gap of, okay, if this dissection is properly diagnosed, what

happens? What surgery is performed? What are the chances of survival? So he is

not rendering opinions of standard of care.”

Plaintiff’s counsel later stated that defendants were trying to prevent plaintiff from bringing what

she needs “to have a trial on the merits of the case to court.” Defense counsel responded that

“[p]laintiff still can have a trial on the merits. He has Dr. Marx. He has not been barred from calling

any fact witnesses, any treating physicians, any lay witnesses, and he has not been barred from

calling Dr. Marx.” Defense counsel also noted his efforts to give plaintiff’s counsel more time—

agreeing to a continuance, corresponding with counsel about discovery, and

“finally fil[ing] the motion to bar as a last act, because I didn’t want to file a motion

to bar but the disclosure hadn’t been coming for months and months and months. I

finally filed it. And only after I filed a motion to bar did we get the disclosure.”

¶ 24 After hearing the arguments, the circuit court reasoned as follows:

“I mean that is something I find troublesome here because I wonder why orders are

entered? Why deadlines are set? And this judge, I started my training as a journalist

where deadlines were deadlines. If you didn’t meet the deadline, done. And I think

it’s important that in fairness to both parties to have deadlines, to have rules that

-7-everybody follows. And I really wasn’t even looking at this in terms of sanctions,

but rather looking at the integrity of the Court and the Court’s ability to set

deadlines in order to move cases along.

***

*** The court after considering the pleadings and the arguments that have

been made and taking into account numerous previous orders of the Court setting

deadlines for discovery finds that it would be appropriate and maintain the

integrity of the Court to stick with those deadlines and to bar the disclosure of Dr.

Adams and additional disclosures of Dr. Marx after the deadlines have passed.

The Court does not find any basis for finding that such delay was reasonable.

And for those reasons the Court will grant that in addition to the Court

waiving any prejudgment interest for the period of time that this has caused

delay.”

Despite this ruling, plaintiff requested leave to file an affidavit explaining the reasons for the late

disclosure, and the court granted leave to do so.

¶ 25 By May 18, 2023, plaintiff had not yet filed the explanatory affidavit the circuit

court had permitted her to file. The court at that point issued its order granting defendants’ motion

to bar the late-disclosed supplemental opinion of Marx and effectively any opinions from Adams.

The court also tolled all prejudgment interest accrued between February 20, 2022, and April 20,

2023. The same day, defendants issued a notice of deposition of Marx, scheduled for June 7, 2023.

¶ 26 During his June 2023 deposition, Marx repeatedly indicated that he is not a

cardiothoracic surgeon. He stated that

“the radiologist needed to call the abnormality on the chest X-ray, recommend a

-8-CT angiogram. Given the presence of chest pain, a CT angiogram would have

diagnosed the aneurysm and the dissection and that information could have been

used by the emergency room department and the referring cardiothoracic surgeon

to figure out what they wanted to do for this patient.”

He later indicated that aortic aneurysms are not always emergencies and stated:

“I am not a cardiothoracic surgeon, but many people live with aneurysms for many

years. I think the criteria for surgery is size, rapid change in size or pain. Again, I

am not a surgeon *** Some dissections are chronic and are not treated or can be

treated medically. Others are emergencies or need to be corrected surgically, but

who falls into what category I would leave to a cardiothoracic surgeon.”

When specifically asked moments later whether he would defer opinions as to the appropriate

treatment of aortic dissection, he again answered in the affirmative. He testified that his “job as a

radiologist is to report [aortic aneurysms], give dimensions, any other findings that might be

associated with an aneurysm, such as the dissection.”

¶ 27 He also testified that he had patients in the past who were referred to surgery as a

result of a diagnosis of an aortic dilation, dissection, or aneurysm. When asked whether they

survived, he stated:

“I don’t have a particular recollection of a particular case to opine or to answer that

question, but obviously replacement of a thinning thoracic aorta due to an aneurysm

and dissection is a major surgery. It is my impression, not being a cardiothoracic

surgeon, that most patients would survive that operation successfully.”

Defense counsel objected to this statement for lack of foundation. Marx later indicated that surgery

is the “most common way once these are diagnosed.” Furthermore, he stated that, “[b]ased on my

-9-experience, if you made the diagnosis of an ascending aortic dissection and aneurysm in a patient

with acute pain, they would have had timely surgery, meaning rapid surgery, and the patient, in

my experience, would survive.”

¶ 28 E. Motion to Reconsider

¶ 29 On June 19, 2023, plaintiff filed her motion to reconsider, accompanied by her

attorney’s affidavit. The affidavit details plaintiff’s counsel’s unexpected need to devote

significant time to cases other than this one from December 2022 until April 2023. This was

offered as the explanation for the late disclosures without requesting an extension, which the

affidavit stated was not intended to undermine the circuit court’s authority.

¶ 30 In November 2023, the circuit court held a hearing on the motion to reconsider.

Among other arguments, defense counsel expressed that he “did not want to incur the cost of taking

his expert’s deposition until [he] had the entire disclosure.” There was also some disagreement

about the appropriate role the affidavits should play in the analysis on a motion to reconsider.

Plaintiff took the position that the court granted leave to file the affidavits, and defense counsel

agreed. However, defense counsel argued that the appropriate time to file the affidavits would have

been during the initial motion to bar proceedings, not during the motion to reconsider. The court

ultimately agreed with defendants and did not consider the affidavits.

¶ 31 During that hearing, the circuit court alluded to the fact that, in another case,

plaintiff’s counsel had relied upon the adverse discovery ruling in this case to argue the opposite

position. Specifically, plaintiff’s counsel argued in the separate matter that “what’s good for the

goose is good for the gander” in an attempt to impose sanctions on the other party. Plaintiff’s

counsel admitted to this and attempted to reconcile this positional conflict by arguing that he was

not challenging the imposition of sanctions in the present case so much as the sanction chosen:

- 10 -that of barring the late-disclosed expert and opinions.

¶ 32 After hearing argument, the circuit court said it considered the relevant factors

cumulatively instead of any one factor exclusively and held as follows:

“Even though this case law wasn’t argued at the motion and it was brought to the

attention of the Court in the motion for reconsideration, I believe the Court has

considered all of those factors, and I don’t believe that there’s anything to suggest

that any of those factors are controlling or that any of those factors might indeed

overlap or be conjoined in some way with regard to the arguments that were made

about surprise and prejudicial effect. I think surprise, if you look at the basis for

why a Court would even recognize such a notion of surprise as a factor, it is because

of the goal of preventing gamesmanship. And I can’t think of—well, the Court,

after hearing all of the arguments and the factors that were argued both at the

original hearing as well as today, the Court has not yet heard an explanation for

why deadlines were not met that were set. And the plaintiff certainly had an

opportunity to seek extensions of deadlines, and I haven’t heard any argument or

explanation as to why those extensions of deadlines were not sought. I think that is

part of surprise to a—to a party not meeting deadlines. I for one as a judge believe

that deadlines are important. And my background before I was an attorney was as

a journalist. We had deadlines. And if you didn’t hit the deadline, your story is

dead. That’s why they called it deadline. And unless there was some type of

extension, it wasn’t possible for that to survive. Here certainly it’s easy enough for

an attorney to seek an extension of a deadline. And I think barring a reasonable

explanation for why those extensions were not sought—and nothing has been raised

- 11 -in this matter suggesting that—I think that overlaps also into the sixth factor, which

was good faith. I think all of these factors kind of work together in ensuring that

they don’t have gamesmanship, that we have cases proceed in a workable fashion.

I do find that the defendants have shown prejudicial effect of these late disclosures.

I do find that the defendant was diligent in pursuing plaintiff’s discovery. I do find

that the defendants’ objection was timely. I do find that in this motion for

reconsideration there’s been no new case law raised.”

The circuit court issued an order in November 2023 denying the motion to reconsider.

¶ 33 In December 2023, plaintiff filed a motion requesting leave to appeal pursuant to

Illinois Supreme Court Rule 308 (eff. Oct. 1, 2019), which the circuit court denied in February

2024 after a brief hearing on the issue. On August 9, 2024, the court set a deadline of October 4,

2024, for the disclosure of defendants’ Rule 213(f)(3) experts. The case was set for a case

management conference October 18, 2024, to “discuss deposition deadlines for Defendants’

experts and a trial date.” Defendants disclosed their experts in September 2024.

¶ 34 F. Motion for Summary Judgment

¶ 35 Shortly after disclosing their experts, defendants filed a motion for summary

judgment, arguing plaintiff failed to present evidence to establish that the claimed negligence

proximately caused decedent’s death. Specifically, defendants argue that plaintiff’s case rests on

the assumption that an earlier diagnosis by Hurst would have led to successful surgical treatment,

but there is no expert opinion from a cardiothoracic surgeon that an earlier diagnosis would have

led to earlier treatment or that the treatment would likely have been successful.

¶ 36 In February 2025, the circuit court set a trial date for January 2026.

¶ 37 In November, after full briefing from the parties, the circuit court held a hearing on

- 12 -the motion for summary judgment. After the parties’ arguments, the court reasoned that

“the Court has made rulings in this case barring testimony, and nothing—nothing

within those rulings would alleviate the burden that the Plaintiff has in presenting

its case, particularly with regard to the issue of proximate cause.

The Court has reviewed the totality of everything that’s been presented in

the pleadings, in the attachments. The Court really is left with a finding and

understanding that the evidence and testimony that’s been presented does not

satisfy the plaintiff’s burden on the issue of proximate cause. Opinions offered by

the plaintiff do not meet the requisite degree of medical certainty regarding

proximate cause. *** [T]he Court has reviewed Dr. Marx’s supplemental opinions

that even though—even though those were barred in this case, as is the Court’s

understanding of earlier rulings that the Court has made, I’m not considering those

opinions. I have looked at what has been presented, but even if I had considered, I

do not believe that the burden has been met here; and for those reasons and the

reasons [that] have been discussed today ***.”

In December, the court issued its order granting the motion for summary judgment.

¶ 38 This appeal followed.

¶ 39 II. ANALYSIS

¶ 40 A. Precluding Expert Testimony

¶ 41 Plaintiff argues that the barring of Adams’s and Marx’s late-disclosed opinions is

purely punitive and an abuse of discretion. She does not challenge the imposition of sanctions

generally and acknowledges that she failed to abide by the deadlines to file expert witness

disclosures. Rather, she argues the specific sanction outweighs the wrongdoing to such an extent

- 13 -that no reasonable court would have imposed it.

¶ 42 1. General Principles

¶ 43 Illinois Supreme Court Rule 213(f) (eff. Jan. 1, 2018) requires parties to furnish

information about their expert witnesses, including, for independent expert witnesses, the subjects

on which each will testify and the opinions the party expects to elicit. For controlled expert

witnesses, like those at issue here, Illinois Supreme Court Rule 213(f)(3) (eff. Jan. 1, 2018) requires

the party to further disclose the bases for all the witnesses’ opinions and to produce any reports

prepared by the witnesses about the case.

¶ 44 Illinois Supreme Court Rule 219(c)(iv) (eff. July 1, 2002) states that the

unreasonable failure to comply with the rules or orders of the circuit court allows the court to enter

orders that are just, including barring a witness from testifying. In this context, the “orders of the

circuit court” at issue are most likely to be case management orders entered pursuant to Illinois

Supreme Court Rule 218 (eff. Feb. 2, 2023). Among the matters Rule 218 directs courts to address

are “the area of expertise and the number of expert witnesses who may be called” and “deadlines

for the disclosure of witnesses.” Ill. S. Ct. R. 218(a)(5)(ii), (iii) (eff. Feb. 2, 2023). The supreme

court’s rule directs that “[a]ll dates set for the disclosure of witnesses, including rebuttal witnesses,

and the completion of discovery shall be chosen to ensure that discovery will be completed not

later than 60 days before the date on which the trial court reasonably anticipates that trial will

commence.” Ill. S. Ct. R. 218(c) (eff. Feb. 2, 2023). The “rule is to be liberally construed to do

substantial justice between and among the parties.” Id.

¶ 45 When analyzing a circuit court’s decision under Rule 219 to preclude expert

testimony at trial, the standard of review is abuse of discretion. Parker v. Illinois Masonic Warren

Barr Pavilion, 299 Ill. App. 3d 495, 501-02 (1998). As the Illinois Supreme Court has noted, this

- 14 -is “the most deferential standard of review available with the exception of no review at all.”

(Internal quotation marks omitted.) People v. Coleman, 183 Ill. 2d 366, 387 (1998). A circuit court

abuses its discretion only when its decision is “arbitrary, fanciful or unreasonable [citation] or

where no reasonable person would agree with the position adopted by the [circuit] court.” People

v. Becker, 239 Ill. 2d 215, 234 (2010). In this context, it has been said that the “circuit court abuses

its discretion only if it acts arbitrarily without the employment of conscientious judgment, exceeds

the bounds of reason and ignores recognized principles of law, or if no reasonable person would

take the position adopted by the circuit court.” Frulla v. Hyatt Corp., 2018 IL App (1st) 172329,

¶ 26.

¶ 46 Moreover, when assessing whether the sanction was an abuse of discretion, we

examine the same factors the circuit court considers when deciding whether to exclude a witness

as a discovery sanction: “(1) the surprise to the adverse party; (2) the prejudicial effect of the

testimony; (3) the nature of the testimony; (4) the diligence of the adverse party; (5) the timely

objection to the testimony; and (6) the good faith of the party calling the witness.” Sullivan v.

Edward Hospital, 209 Ill. 2d 100, 110 (2004) (hereinafter referred to as the Sullivan factors). As

plaintiff recognizes, each case is to be considered based on its unique factual situation. Boatmen’s

National Bank of Belleville v. Martin, 155 Ill. 2d 305, 314 (1993). No single factor is determinative.

In re Estate of Kline, 245 Ill. App. 3d 413, 433 (1993). A reviewing court is to focus on whether

the record provides an adequate basis for upholding the decision to sanction. Lake Environmental,

Inc. v. Arnold, 2015 IL 118110, ¶ 16.

¶ 47 2. The Sullivan Factors

¶ 48 Plaintiff argues that the circuit court did not consider the Sullivan factors in making

its ruling. We disagree. Though the court may not have specifically referenced the Sullivan factors

- 15 -when making its initial ruling, it acknowledged that it had considered the parties’ arguments.

Moreover, at the hearing on the motion to reconsider, the court expressly acknowledged them and

indicated that its original ruling was consistent with its consideration of the factors. “[I]t is a

fundamental principle of appellate law that when an appeal is taken from a lower court judgment,

the question before the court of review is the correctness of the result, not the correctness of the

reasoning on which the result was reached.” (Internal quotation marks omitted.) People v. White,

2025 IL App (2d) 240477, ¶ 41 (citing People v. Johnson, 208 Ill. 2d 118, 128 (2003)).

Furthermore, this rule has applied in the context of reviewing sanctions for an abuse of discretion.

Arnold, 2015 IL 118110, ¶ 16. We therefore examine the Sullivan factors individually.

¶ 49 a. Surprise

¶ 50 Regarding the first factor, pertaining to the surprise to the defendants, plaintiff

argues that there was no unfair surprise because there was still time for expert discovery.

Specifically, she points to the fact that no trial date was set in this matter. Initially, we observe that

this case had been set for trial at one time, but that trial date was canceled due to the slowness of

plaintiff’s disclosures.

¶ 51 It is conceded that, though plaintiff was given time to supplement her earlier

disclosure of Marx’s opinions, it was not until February 2, 2023, that plaintiff’s counsel first

advised defense counsel of the intention to obtain an expert in the field of cardiothoracic surgery.

In other words, this was not a development that had been explicitly discussed in the preceding

years in which the case was pending.

¶ 52 Defendants were not surprised by the disclosure of new opinions from Marx, as a

supplemental disclosure of his opinions had been clearly anticipated for quite some time. They

were, however, surprised by the addition of a new and previously undisclosed expert. Still, this is

- 16 -not the same degree of surprise that would be generated by a disclosure at or near to trial;

consequently, it weighs only slightly in favor of the circuit court’s sanction. The prejudice suffered

as a result of the late disclosure is discussed next.

¶ 53 This factor alone does not weigh in favor of a sanction barring the late-disclosed

testimony. The import of the circuit court’s scheduling orders, however, will be discussed below.

¶ 54 b. Prejudice

¶ 55 Plaintiff’s argument with respect to prejudice is largely the same as that concerning

surprise. There was no trial date set, so defendant still had time to conduct discovery of the new

expert and new opinions. Initially, we observe that this case had been set for trial at one time, but

that trial date was canceled due to the slowness of plaintiff’s disclosures.

¶ 56 Furthermore, whether a circuit court sets a future trial date falling at the end of a

long discovery schedule or only as discovery nears completion is a courtroom management

decision within the circuit court’s discretion. Here, the circuit court attempted both methods, and

neither succeeded. The first trial date was canceled because of plaintiff’s lagging disclosures, and

the late disclosures at issue would prevent a trial date from happening for months. The likelihood

is that defendants would wish to retain their own cardiothoracic expert; locating, retaining, and

disclosing the opinions of such an expert would add to the time necessary before the trial could be

scheduled.

¶ 57 More fundamentally, we cannot agree with plaintiff’s implication that, so long as

no trial date has yet been set (or, in this case, reset), no discovery violation can earn a severe

sanction. As we discuss further below, scheduling orders entered by a circuit court serve an

important purpose and must be respected. Other cases have precluded expert testimony because of

a missed deadline, even when there was no trial date set. See, e.g., Castro v. South Chicago

- 17 -Community Hospital, 166 Ill. App. 3d 479, 480-83 (1988) (analyzing Illinois Supreme Court Rule

220 (eff. Oct. 1, 1984) and holding that the circuit court did not abuse its discretion in disqualifying

late-disclosed experts even when there was no trial date set); Mitchell v. Wayne Corp., 180 Ill.

App. 3d 796, 800, 802 (1989) (holding that circuit court did not abuse its discretion in barring an

expert witness due to late disclosures, even when there was no trial date set).

¶ 58 In assessing prejudice, we are really considering undue prejudice. The issue is not

whether defendants would be prejudiced by the new opinions but by the late disclosure of those

opinions. In our view, the only prejudice that defendants suffered from the late disclosure was the

possible delay of a future trial date as a result of the untimely disclosures. This weighs only very

slightly in favor of a discovery sanction.

¶ 59 c. Nature of the Witnesses’ Testimony

¶ 60 The parties devote little space in their briefs to discussing the third Sullivan factor:

the nature of the witnesses’ testimony. As discussed more completely below, the general rule is

that the plaintiff in a medical malpractice case must present appropriate expert testimony on the

issue of proximate cause. Simmons v. Garces, 198 Ill. 2d 541, 556-57 (2002). While barring such

testimony can have harsh consequences, the need for it should come as no surprise.

¶ 61 Furthermore, given the importance of expert testimony in malpractice cases,

disclosure and discovery of their opinions is of central importance. The obligation of disclosure is

at its zenith when it comes to controlled expert witnesses like Marx and Adams. Slow disclosure

of expert opinions has a ripple effect on the ultimate timeline for the completion of discovery and

trial.

¶ 62 We conclude that this factor weighs in favor of the sanction imposed.

¶ 63 d. Defendants’ Diligence and Timeliness

- 18 -¶ 64 Relevant to the fourth and fifth factors, regarding defendants’ diligence and

timeliness, plaintiff argues that they cannot now claim prejudice from continuing the trial because

they had agreed to it. Perhaps defendants agreed to the continuance, but it does not change the fact

that their agreement was made necessary by plaintiff’s delays. Furthermore, we will not punish

defendants for attempting to accommodate plaintiff. We view their agreement to a continuance as

a diligent, earnest, and cooperative effort to keep the litigation on track. Indeed, they were thinking

months ahead, filing a motion to compel and subsequently writing to plaintiff in July 2022 to ask

about a joint extension, given the trial date in November of that year. Even plaintiff has

acknowledged that the rules are intended to enable the parties to work together, discourage tactical

gamesmanship, and avoid surprise. Contrary to this notion is her suggestion that defendants’

agreement to a continuance is in some way a mark against them. Defendants acted promptly instead

of letting the matter sit for future adjudication.

¶ 65 We find that this factor weighs distinctly in favor of the sanction imposed.

¶ 66 e. Plaintiff’s Good-Faith Efforts to Comply

¶ 67 The sixth factor pertains to whether plaintiff had exerted good-faith efforts in

meeting the deadlines. We agree that plaintiff did not completely abandon her responsibilities, but

she fell short of the mark on more than one occasion. Discovery was served on her in July 2019,

but 10 months later, defendants were still required to file a motion to compel. As discussed above,

plaintiff’s lack of a response to defendants’ requests to supplement her expert disclosures played

a major role in scuttling the trial set for November 2022. In September 2022, plaintiff was ordered

to disclose expert opinions within 45 days; she failed to do so. The deadline was extended to

December 30; plaintiff again failed to comply. Plaintiff filed no motion seeking additional time,

apparently intending to ask for forgiveness rather than permission.

- 19 -¶ 68 On February 2, 2023, plaintiff’s counsel left a voicemail for opposing counsel

indicating that supplementation would be coming “shortly.” On February 10, 2023, she disclosed

Marx’s supplemental opinions but nothing about Adams’s opinions. She finally made a disclosure

of Adams’s opinions on February 17, 2023. This was 5 months after she was ordered to make the

disclosure and 1½ months after an extended deadline. Watching two deadlines come and go makes

a poor case for finding good faith.

¶ 69 Plaintiff filed affidavits along with her motion to reconsider the circuit court’s

rulings, which describe an exceptionally busy period at plaintiff’s counsel’s law firm from

December 2022 to April 2023. However, the lack of diligence exceeds that period on each end.

Plaintiff indicated as early as April 2022 that the supplemental disclosures were forthcoming soon,

and her claimed office difficulties did not begin until six months later. Furthermore, she was able

to make her disclosures in February 2023, so any continuing difficulty beyond that time seems to

be unrelated to the issues here. In any event, these were matters not brought forward at the time of

the hearing on the motion to bar and were raised only at reconsideration. The court was justified

in not considering these newly raised matters. See Gardner v. Navistar International

Transportation Corp., 213 Ill. App. 3d 242, 248-49 (1991) (stating that “the interests of finality

and efficiency require that the trial courts not consider such late-tendered evidentiary material, no

matter what the contents thereof may be” (emphasis in original)).

¶ 70 We find that this factor weighs in favor of the sanction imposed.

¶ 71 f. Consideration of All Factors

¶ 72 Our role here is not to reweigh the Sullivan factors as they apply here but to

determine whether the circuit court acted within its discretion in concluding that they weighed in

favor of barring the late-disclosed testimony. As noted above, the abuse of discretion standard is

- 20 -greatly deferential to the lower court. We note that the court could have made its ruling more

clearly defensible if the record showed that it engaged in progressive sanctions or if it made clear

to the parties that the somewhat lax management of the case earlier in its life would be coming to

an end and that the deadlines set in late 2022 would be more strictly enforced. On the latter point,

we note that plaintiff has not included a transcript of the proceedings from the dates on which those

deadlines were set.

¶ 73 Plaintiff relies heavily on Shimanovsky v. General Motors Corp., 181 Ill. 2d 112

(1998), and Besco v. Henslee, Monek & Henslee, 297 Ill. App. 3d 778 (1998), in support of her

contention that the circuit court’s sanction was too severe. We find both cases to be distinguishable.

¶ 74 Shimanovsky dealt with a sanction for allegedly destroyed evidence, not failing to

abide by a court order. Moreover, the sanction imposed—outright dismissal—was even more

severe than the sanction imposed here. See Shimanovsky, 181 Ill. 2d at 128-29. The issues were

more on point in Besco, but the circumstances were different. In Besco, both parties were

responsible for numerous discovery delays, the case was still in the early stages of discovery, and

the expert was the plaintiff’s only expert. Additionally, the defendants there were alleged to be

part of the reason for the delay in disclosure. Besco, 297 Ill. App. 3d at 783. Again, this case does

not bear the same characteristics.

¶ 75 Our ultimate conclusion, given the deferential standard of review, is that the circuit

court acted within its discretion in determining that the sanction of barring the testimony was

appropriate.

¶ 76 3. The Court’s Sanction Is Not Punishment

¶ 77 Plaintiff argues the circuit court order constituted punishment, contravening notions

in our case law that “the punishment should fit the crime” (Coleman v. Abella, 322 Ill. App. 3d

- 21 -792, 800 (2001)) and that a court “may not impose sanctions that are intended primarily as

punishment” (Ruane v. Amore, 287 Ill. App. 3d 465, 472 (1997)).

¶ 78 It is true that the purpose of a discovery sanction “is to coerce compliance with

discovery rules and orders, not to punish the dilatory party.” Shimanovsky, 181 Ill. 2d at 123. From

the perspective of the sanctioned party, however, the end result of a significant sanction can feel

like punishment regardless of its purpose. Other cases have upheld severe sanctions that the

affected party might have perceived as punishment. In Prather v. McGrady, 261 Ill. App. 3d 880,

887 (1994), a party’s expert was barred for noncompliance with the court’s scheduling order; that

sanction was not “punishment.” Moreover, repeated violations of court orders may properly lead

to outright dismissal. Sander v. Dow Chemical Co., 166 Ill. 2d 48, 67 (1995). A sanction should

not be characterized as “punishment” simply due to its severity.

¶ 79 Here, looking at the context for the circuit court’s orders, we conclude that they

were not intended as punishment but were simply actions in enforcement of its Rule 218

scheduling orders. A case management order is intended to bring a case to trial following the

orderly progress of discovery. While the end of the process is the trial, the deadlines established

pursuant to a case management order are themselves important benchmarks along the road to that

end. Simply stating that the case had not yet been set (or here, reset) for trial overlooks the

relevance and importance of the schedule the court establishes to reach that goal. When the court

issued a discovery sanction in Clymore v. Hayden, 278 Ill. App. 3d 862, 869 (1996), for the failure

to abide by its orders, it invoked the supreme court’s admonition that “court rules and orders are

not merely suggestions to be complied with if convenient.” Id. (citing People v. Wilk, 124 Ill. 2d

93, 103 (1988)). Instead, they “constitute obligations that counsel disregard at their personal peril

and that trial courts must enforce.” (Emphasis in original.) Id.

- 22 -¶ 80 Other developments have reinforced the importance of Rule 218 case management

orders. The Illinois Supreme Court’s strategic agenda identifies the goal to have a court system

“that resolves disputes fairly and timely.” Ill. Jud. Branch, Illinois Judicial Branch Strategic

Agenda 2026-2028 at 10 (January 2026), available at https://ilcourtsaudio.blob.core.windows.

net/antilles-resources/resources/cbe12922-0fc6-4af0-a1d8-352337d28f7d/2026-2028%20Strategic%20Agenda.pdf [https://perma.cc/XPN5-KD4C]. The supreme court has also

adopted time to disposition standards that specify that 98% of even complex cases should be

resolved within 36 months of filing. Ill. S. Ct., Time Standards for Case Closure in the Illinois

Trial Courts (July 1, 2022), available at https://ilcourtsaudio.blob.core.windows.net/antillesresources/resources/f5cdd7d7-49b1-409e-b556-56c1f55060c3/M.R.%2031228%20-%20

Time%20Standards%20for%20Case%20Closure%20in%20the%20Illinois%20Trial%20

Courts%20-%2003-25-22.pdf [https://perma.cc/MVE2-LUPF]. This case is not subject to the

standards only because it is too old; it began three years before the standards were adopted. Still,

circuit courts are being asked to be more sensitive to the time it takes to resolve cases in our courts.

¶ 81 When making its ruling here, the circuit court cited the justice system’s integrity

and the importance of adhering to deadlines. This consideration finds resonance in established

caselaw. The Illinois Supreme Court has upheld sanctions based on “maintaining the integrity of

our court system.” Sander, 166 Ill. 2d at 68. Further, we have permitted courts to bar witnesses to

manage their dockets, prevent delays, and control discovery. See Baxter v. Mount Sinai Hospital

Medical Center of Chicago, 2026 IL App (1st) 241968-U, ¶ 27; see also Amoco Oil Co. v. Segall,

118 Ill. App. 3d 1002, 1013 (1983) (stating that the purpose of sanctions is not to punish litigants

but rather to accomplish the object of discovery and promote the unimpeded flow of litigation).

And we have permitted circuit courts the discretion to enforce court-ordered deadlines, treat those

- 23 -orders as law, and determine what sanctions to impose. See Baxter, 2026 IL App (1st) 241968-U,

¶ 20; see also Department of Transportation v. Crull, 294 Ill. App. 3d 531, 538-39 (1998)

(reasoning that Rule 213 establishes more exacting requirements for disclosure of expert witnesses

than did the former Rule 220 and, as such, “[t]rial courts should be more reluctant under Rule 213

than they were under former Rule 220 (1) to permit the parties to deviate from the strict disclosure

requirements, or (2) not to impose severe sanctions when such deviations occur”).

¶ 82 Simply put, we cannot ask our circuit courts to take a firm hand in setting deadlines

to manage their cases and then too lightly set aside steps taken in enforcement of those deadlines.

Here, a trial date was set and then stricken because of plaintiff’s initial slowness in responding to

discovery. Only three months after the trial date was stricken, the court set a specific deadline for

plaintiff to complete her expert disclosures; she ignored it. The court extended the deadline again;

plaintiff ignored it again. The complete disclosure was not made until a month and a half after the

extended deadline. We do not find it an act of “punishment” for the circuit court to treat its orders

as just that—orders.

¶ 83 Plaintiff also argues that there is a future and final opportunity for her to disclose

her experts and their opinions: at deposition. It is true that Rule 213(g) limits a witness’s testimony

on direct examination to “information disclosed in answer to a Rule 213(f) interrogatory, or in a

discovery deposition.” (Emphasis added.) Ill. S. Ct. R. 213(g) (eff. Jan. 1, 2018). This does not

mean, as plaintiff implies, the discovery obligations under Rule 213(f) concerning interrogatories

are optional or meaningless. It is true that Rule 213(f) requires a more modest disclosure of the

opinions of an independent expert and less still of the expected testimony of a lay witness. See Ill.

S. Ct. R. 213(f)(1), (2) (eff Jan. 1, 2018). For a controlled expert, such as those at issue here,

however, the required disclosure via interrogatory is extensive, extending to the conclusions and

- 24 -opinions of the witness and all bases therefor. Ill. S. Ct. R. 213(f)(3) (eff. Jan. 1, 2018).

¶ 84 Consequently, while a party may choose to depose the opponent’s controlled expert

witness to probe the expert’s opinions and reasoning, the deposition is not intended to be the time

to learn of wholesale new and previously undisclosed opinions. “The party propounding the expert

is generally required to disclose the expert’s opinion before the deposition, not at the deposition.”

(Emphasis in original.) Schuler v. Mid-Central Cardiology, 313 Ill. App. 3d 326, 332 (2000).

¶ 85 For all the foregoing reasons, we conclude that the circuit court did not abuse its

discretion when it barred plaintiff’s disclosures made well after the court’s established—and

extended—deadline.

¶ 86 B. Motion for Summary Judgment

¶ 87 Plaintiff argues that granting defendants’ motion for summary judgment was

erroneous because the expert testimony makes a prima facie showing of proximate causation in

support of the medical negligence claim. Defendants, in turn, argue that summary judgment was

proper because plaintiff lacked the expert testimony needed to establish proximate cause.

¶ 88 The Code of Civil Procedure allows a defendant to file a motion for summary

judgment “at any time.” 735 ILCS 5/2-1005(b) (West 2024). Furthermore, summary judgment is

appropriate when the pleadings, depositions, and admissions on file, together with any affidavits,

when viewed in the light most favorable to the nonmovant, reveal that no genuine issue of material

fact exists and that the movant is entitled to judgment as a matter of law. State Farm Fire &

Casualty Co. v. Martinez, 384 Ill. App. 3d 494, 497-98 (2008). “[A]ny evidence which would be

inadmissible at trial cannot be considered by the court in support of or opposition to a motion for

summary judgment.” Watkins v. Schmitt, 172 Ill. 2d 193, 203-04 (1996). If what is contained in

the pleadings and affidavits would have constituted all the evidence at trial, then a summary

- 25 -judgment should be entered. Jones v. Pneumo Abex LLC, 2019 IL 123895, ¶ 25.

¶ 89 Here, defendants filed a variety of summary judgment motion sometimes called a

Celotex motion, a term derived from the United States Supreme Court’s decision in Celotex Corp.

v. Catrett, 477 U.S. 317 (1986). Jiotis v. Burr Ridge Park District, 2014 IL App (2d) 121293, ¶ 25.

A Celotex motion asserts that the nonmoving party’s evidence is insufficient to avoid judgment as

a matter of law.

¶ 90 Because this action asserts a claim of medical negligence, plaintiff must establish

the breach of a duty that proximately caused injury to her decedent. Rohe v. Shivde, 203 Ill. App.

3d 181, 192 (1990). As a general rule, a plaintiff must establish proximate causation in a medical

negligence case through expert testimony. Simmons, 198 Ill. 2d at 556-57; see Thompson v.

LaSpisa, 2023 IL App (1st) 211448, ¶¶ 40-41 (discussing exceptions to the general rule). While

there is no dispute here concerning the adequacy of the evidence in other respects, the question is

whether plaintiff has adduced sufficient evidence to create an issue of fact as to the issue of

proximate cause.

¶ 91 We review a grant of summary judgment de novo. Bright v. Yenchko, 2026 IL

132015, ¶ 14.

¶ 92 1. The Expert Testimony of Record

¶ 93 Here, we accept plaintiff’s assertion that the evidence is sufficient to create an issue

of fact as to the following: (1) that defendant Hurst should have seen signs on the X-ray of the

need for additional action; (2) that, if he had seen such signs, Hurst would have ordered a CT scan

with contrast; (3) that, if such a test had been conducted, it is highly likely it would have led to

diagnosis of decedent’s aortic dissection; and (4) that such a diagnosis would have led to

consultation with a cardiothoracic surgeon. The issue boils down to the adequacy of the evidence

- 26 -to support plaintiff’s final assertion: “that the consult would have led to surgery” that would have

“likely been successful.”

¶ 94 We need not consider whether Adams might have provided the necessary

testimony, as he was barred as a witness. As discussed above, we conclude that the circuit court

acted within its discretion in that determination. We have repeatedly granted summary judgment

based on a gap in the plaintiff’s evidence that could only be filled by an already precluded expert

witness. See Smith v. Bhattacharya, 2014 IL App (2d) 130891, ¶ 21 (affirming summary judgment

and finding no abuse of discretion when the circuit court barred expert testimony for failure to

abide by the disclosure deadline even when trial was months away); see also Bennett v. Raag, 103

Ill. App. 3d 321, 327-28 (1982) (affirming summary judgment in medical negligence claim when

necessary expert testimony was barred); James v. Yasunaga, 157 Ill. App. 3d 450, 457 (1987)

(affirming summary judgment and finding no abuse of discretion when the circuit court barred

expert testimony for failure to abide by the disclosure deadline even when the discovery deadline

had not passed and trial was months away).

¶ 95 Beyond Adams, plaintiff points to other physicians who, as she puts it, “address

this ‘gap’ ” in proximate cause testimony. The irony here is that it is undisputed that these other

specialties are not medically competent to administer the treatment at issue, but plaintiff relies on

them to offer testimony on what treatment was necessary and the chances that it might succeed.

Examination of the proffered opinions of each such witness shows that they fall short of the mark.

¶ 96 Plaintiff argues that Marx would testify that, had a cardiothoracic surgeon been

consulted, her decedent “would have had *** timely surgery” and he is of the opinion “that most

patients who have this kind of surgery in a timely fashion before the aneurysm ruptures survive.”

But Marx is a radiologist, not a cardiothoracic surgeon, and he agreed that not every aneurysm is

- 27 -an emergency requiring surgery. We do not know the likelihood that decedent’s presentation on a

hypothetical CT scan would lead a surgeon to judge that surgery was the appropriate treatment for

this patient, and we do not know the likelihood that surgery would have been successful. Marx

concedes that it would be up to the surgeon to “figure out what they wanted to do for this patient.”

If the surgeon did choose to act promptly, Marx said that he would defer to the surgeon on the

appropriate treatment.

¶ 97 Under Aguilera v. Mount Sinai Hospital Medical Center, 293 Ill. App. 3d 967, 974-75 (1997), bare statements from experts about survival rates increasing if the missing medical

treatment had been provided is, by itself, the kind of insufficient speculative expert testimony that

does not create an issue of fact for the jury. Without factual bases supporting the expert opinion,

“the opinions offered by the plaintiff’s experts *** must be viewed as conjecture.” Id. at 976.

Marx’s testimony about what he has seen happen with other patients is also “contingent,

speculative or merely possible.” (Internal quotation marks omitted.) Id.; see Ayala v. Murad, 367

Ill. App. 3d 591, 601-02 (2006) (reasoning that an expert’s ability to testify in general terms is

insufficient to establish proximate cause). The testimony functions more as a limited recollection

of his experience rather than an expert opinion based on medical science. It shows that, while he

interacts with cardiothoracic surgeons, he is not a specialist or practitioner in that area. Marx’s

testimony is not similar to that in Hemminger v. LeMay, 2014 IL App (3d) 120392, ¶¶ 22-25, where

a qualified expert provided a statistical analysis comparing the odds of survival during stage 1 of

the cancer versus stage 3 of the cancer and supplemented that with her own professional

experience, knowledge, and training, which established a prima facie case of proximate cause to a

“reasonable degree of medical certainty.”

¶ 98 As to Brown, the emergency room physician, plaintiff’s disclosure offered a few

- 28 -boilerplate generalities on the topics on which he might testify, but it did not specifically mention

experience with cardiothoracic surgery. At his deposition, he testified that, if he had diagnosed

someone with an aortic dissection at the emergency room, he would have immediately called a

cardiothoracic surgeon. Over the course of his 20-plus-year career, he has had a cardiothoracic

surgeon come in and perform the surgery a handful of times, and he believes the patient lived in

those instances. However, this testimony is largely based on his sporadic experience working

upstream from cardiothoracic surgeons and is not based on his own medical expertise. Indeed, he

also testified that, due to his specialty, he could not formulate an opinion about whether decedent

passed away because of an aortic dissection. For similar reasons applicable to Marx’s testimony,

Brown’s testimony does not create a genuine issue of material fact about proximate cause. He

offers anecdotal evidence of what he has seen but not opinions to a reasonable degree of medical

certainty about what plausibly would occur with this patient.

¶ 99 Defendant Hurst himself was named as an independent expert witness, but he seems

like an unlikely candidate to provide the missing link in plaintiff’s evidence of proximate cause.

During his deposition, he testified that he is a radiologist. When asked, he indicated that a CT scan

with contrast is the gold standard for diagnosis of an aortic aneurysm with accuracy, with a

probable accuracy rate of higher than 95%. However, he did not opine on the likelihood that such

a radiographic result would lead to surgery or whether surgery would have been successful. He

also directly stated that he would not be offering opinions in this case about cardiology or

cardiothoracic surgery. This, too, fails to create a genuine issue of material fact on the issue of

proximate cause, for reasons similar to those described above.

¶ 100 2. Applicability of Dunbar v. Carlson

¶ 101 Plaintiff also argues that summary judgment is inappropriate because, even if a

- 29 -prima facie case has not been established yet, it could be at trial. In making this argument, she

relies on Dunbar v. Carlson, 2025 IL App (4th) 241143-U, which distinguishes between the

procedural posture of a motion for summary judgment, in which not all evidence has been heard,

and a judgment notwithstanding the verdict, in which evidence has closed.

¶ 102 Dunbar is distinguishable. Plaintiff suggested it was the now-barred Adams that

would supply the needed testimony on proximate cause: “Dr. Adams is going to kind of fill in the

gap of, okay, if this dissection is properly diagnosed, what happens? What surgery is performed?

What are the chances of survival?” But, as already established, Adams is entirely precluded from

testifying. The other three experts in plaintiff’s disclosure have affirmatively shown that they are

not surgeons and do not perform surgery on the condition at issue; they would defer to surgeons

on the question of if and when cardiothoracic surgery would have occurred and whether it would

have succeeded in resolving the issue. There is no door open to any new or different testimony at

trial concerning proximate cause.

¶ 103 Compare this situation to Dunbar, where we concluded that there were multiple

possible avenues for establishing proximate cause and at least one of those theories was backed by

specific testimony based on objective guidelines, studies, and experience. See id. ¶¶ 53-55.

Furthermore, proximate cause in Dunbar was based on treatments of the patient that had

subsequently occurred and definitively showed their effectiveness. Contrarily, here, decedent

never received surgery, making the relevant expert testimony from a qualified surgeon essential.

¶ 104 To paraphrase Townsend v. University of Chicago Hospitals, 318 Ill. App. 3d 406,

414 (2000), “a [surgeon is] the one required to say [surgery] should have occurred absent the

defendant’s negligence.” Here, however, where the only possible testifying experts would not be

able to offer opinions establishing the element of proximate cause, summary judgment is

- 30 -appropriate. Consequently, the circuit court’s ruling is not erroneous.

¶ 105 3. Applicability of the Lost-Chance Doctrine

¶ 106 As a final matter, we address plaintiff’s brief invocation of the “lost-chance”

doctrine, and we do so mainly to demonstrate that it does not affect our analysis here. The evidence

of record suggests that decedent died because of a dissecting aorta; in other words, that medical

condition is a cause of his death. That does not eliminate the possibility that medical negligence,

such as a delay in treatment, was also a contributing proximate cause. Consequently,

“[t]o the extent a plaintiff’s chance of recovery or survival is lessened by the

malpractice, he or she should be able to present evidence to a jury that the

defendant’s malpractice, to a reasonable degree of medical certainty, proximately

caused the increased risk of harm or lost chance of recovery.” Holton v. Memorial

Hospital, 176 Ill. 2d 95, 119 (1997).

However, this concept “does not relax or lower [a plaintiff’s] burden of proving causation.” Id. at

120. The pattern jury instruction given in other types of tort cases is equally appropriate in lostchance cases. See id. at 110-11.

¶ 107 Furthermore, there is no different or more forgiving rule concerning the necessity

for expert testimony when a plaintiff relies on the lost-chance theory. If anything, the issues are

more complicated by the presence of more than one contributing cause of the injury or death.

Consequently, evidence to a reasonable degree of medical certainty that negligent delay in

diagnosis or treatment lessened the effectiveness of treatment is required. Snelson v. Kamm, 204

Ill. 2d 1, 47 (2003). For that reason, there is no greater tolerance for speculative testimony when a

plaintiff employs the lost-chance theory.

“Contrary to plaintiff’s argument in this case, Hemminger did not signal that

- 31 -a medical expert’s testimony under a lost-chance theory of recovery is subject to a

lower threshold for admissibility. The door is not opened for speculation as to

whether a defendant doctor’s negligence deprived the patient of the opportunity to

undergo treatment that could have been effective if given earlier.” Freeman v.

Crays, 2018 IL App (2d) 170169, ¶ 26.

¶ 108 We find that the importance of such testimony in a case such as this one is well

stated in Thompson, where the plaintiff claimed that an earlier diagnosis of cellulitis would have

prevented its progression:

“In our view, expert testimony would be necessary to establish a proximate

causal relationship for this injury. The difference between how much Thompson’s

facial cellulitis would have progressed had she immediately received emergent

hospital care, versus how much it did progress with those additional 18 hours

lacking such care, requires knowledge beyond the ken of the layperson. We know

there was a delay in her treatment, and we know from her testimony, the medical

records, and the grisly photos that her condition worsened over those 18 hours. We

also know that her swelling improved quite soon after she was hospitalized.

We do not know, however, whether earlier treatment would have prevented

that additional swelling or whether this particular infection would have reached its

full potential anyway, even if immediately treated. We do not know whether or to

what extent her hospital stay would have been shortened, either. To answer these

questions would require a firm knowledge of the finer points of facial cellulitis. The

average person knows nothing of that affliction, its treatment, and its course of

progression; expert testimony was necessary to explain it.” (Emphasis omitted.)

- 32 -Thompson, 2023 IL App (1st) 211448, ¶¶ 45-46.

¶ 109 The fact that plaintiff here is pursuing a theory that negligence caused a lost-chance

theory of recovery does not diminish the need for expert testimony on causation; if anything, it

makes such testimony even more essential.

¶ 110 III. CONCLUSION
