MEMORANDUM **
Oak Park Unified School District (“Oak Park”) appeals the district courts grant of summary judgment on its claims against Philadelphia Indemnity Insurance Company (“Philadelphia”) for breach of the implied covenant of good faith and fair dealing (“bad faith”) and for punitive damages. We have jurisdiction under 28 U.S.C. § 1291. We review a district courts grant of summary judgment de novo, Nodine v. Shiley Inc., 240 F.3d 1149, 1152 (9th Cir. 2001), and we affirm.

1. Oak Park argues that the district court erroneously determined that Philadelphia denied coverage based on a reasonable interpretation of the policy exclusion. Oak Park contends that the district court erred by relying on two cases which interpreted the term “design defect” consistent with Philadelphias interpretation. See Oak Park v. Philadelphia, 2:17-CV-03765, 2017 WL 8288041 (C.D. Cal. Dec. 19, 2017), revd sub nom. Oak Park Unified Sch. Dist. v. Phila. Indem. Ins., 771 F. Appx 757 (9th Cir. 2019); Pasadena Area Cmty. Coll. Dist. v. Phila. Indem. Ins. (“PACC”), LA-17-CV-08569, 2018 WL 6265078 (C.D. Cal. July 27, 2018).

We disagree. Under well-settled California law, a courts subsequent analysis of a policy exclusion can serve as evidence that an insurer acted reasonably when it interpreted the policy similarly. See, e.g., Morris v. Paul Revere Life Ins. Co., 109 Cal.App.4th 966, 135 Cal. Rptr. 2d 718, 726 (2003) (“If ․ the coverage issue turns upon analysis of a legal point—and assuming the governing law has not changed in the interim—the fact that a court had interpreted that law in the same manner as did the insurer, whether before or after, is certainly probative of the reasonableness, if not necessarily the ultimate correctness, of its position.”).
Oak Park also argues that Philadelphia conducted an inadequate investigation before denying coverage. But Oak Park cites no authority suggesting that when an insurer denies coverage based on a reasonable interpretation of a policy exclusion, the insurer might nevertheless be liable for bad faith because it failed to conduct an adequate investigation. Thus, even if the evidence permits an inference that Philadelphia conducted an inadequate investigation, it would be insufficient to overcome summary judgment here.
Oak Park also asserts that Philadelphia merely sought “to pin all of the blame on [Oak Park]” in its investigation, and that Philadelphia “had no idea what its grounds for denial were,” because its Assistant Vice President of Claims could not define “design defect” during her deposition. But this evidence is irrelevant. “[I]n determining whether [a] dispute is ‘reasonable,’ the proper test to apply is an objective one. An insurers subjective state of mind is immaterial.” FEI Enters. v. Kee Man Yoon, 194 Cal.App.4th 790, 124 Cal. Rptr. 3d 64, 74 (2011); see also CalFarm Ins. Co. v. Krusiewicz, 131 Cal.App.4th 273, 31 Cal. Rptr. 3d 619, 629 (2005) (“If the conduct of the insurer in denying coverage was objectively reasonable, its subjective intent is irrelevant.”).

2. Oak Park argues that the district court disregarded the law of the case based on a prior appeal in this case. See Oak Park, 771 F. Appx at 757–58. But that appeal concerned only whether the district court properly concluded that Philadelphia had no duty to defend Oak Park because the relevant “policys exclusionary clause eliminated the possibility of coverage.” Id. at 758. We analyzed the language of the policy exclusion and California authority interpreting the meaning of “design defect,” see id. (citing Cal. Civ. Code § 2784), and concluded that “[b]ecause the[ ] terms are ambiguous, and as exclusions are construed narrowly, we construe these terms in favor of the insured,” id. (citations omitted). We therefore held “that the exclusionary clause did not eliminate the potential for coverage under the ․ policy,” and “Philadelphia therefore had a duty to defend Oak Park.” Id. We did not address whether Philadelphias contrary interpretation of the exclusion was reasonable, and nothing in the memorandum disposition suggests that Philadelphia “ignored” any “factual issues” in its investigation or denial as Oak Park asserts, or that it otherwise acted unreasonably.
“For the [law of the case] doctrine to apply, the issue in question must have been decided explicitly or by necessary implication in [the] previous disposition. A significant corollary to the doctrine is that dicta have no preclusive effect.” Rebel Oil Co. v. Atl. Richfield Co., 146 F.3d 1088, 1093 (9th Cir. 1998) (second alteration in original) (quotation marks and citation omitted); see also United States v. Cote, 51 F.3d 178, 181 (9th Cir. 1995) (“[T]he law of the case acts as a bar only when the issue in question was actually considered and decided by the first court.”). Because the disposition in the prior appeal did not address the bad faith issue or the reasonableness of Philadelphias interpretation of the exclusion, the district court did not violate the law of the case in resolving these issues.

AFFIRMED.

1
. The parties are familiar with the factual and procedural background of this matter. Therefore, we recite only those facts necessary for this disposition.
2
. Oak Park attempts to distinguish PACC by observing that the dispute there centered on the terms “arising out of” and “loss caused by” in the policy exclusion, not “design defect.” While most of the district courts analysis focused on the causal connection between the alleged unsafe condition and the alleged injury, it unquestionably interpreted “design defect” as including a “dangerous and defective condition of the premises.” PACC, 2018 WL 6265078, at *4–5.

. Oak Park also argues that the policy identifies “three separate grounds for exclusion—(i) design defect, (ii) structural maintenance, and (iii) premises defect”—and that the district court inadequately distinguished among these terms. But if the unsafe condition was a “design defect,” then it would have triggered the exclusion regardless of whether it was also a “structural maintenance” problem or a “premises defect.”

. Because Oak Parks claim for punitive damages is derivative of its bad faith claim, and we affirm the district courts grant of summary judgment on bad faith, we likewise affirm summary judgment on punitive damages. See Am. Cas. Co. of Reading, Pa. v. Krieger, 181 F.3d 1113, 1123 (9th Cir. 1999).
