ORDER OF AFFIRMANCE
Appellant filed his petition on June 8, 2020, almost 8 years after issuance of the remittitur on direct appeal on October 10, 2012. Durand v. State, Docket No. 60083 (Order of Affirmance, September 13, 2012). Thus, appellants petition was untimely filed. See NRS 34.726(1). Appellants petition was procedurally barred absent a demonstration of good cause: cause for the delay and undue prejudice. See id. “[T]o demonstrate good cause, a petitioner must show that an impediment external to the defense prevented him or her from complying with the state procedural default rules.” Hathaway v. State, 119 Nev. 248, 252, 71 P.3d 503, 506 (2003).
Based upon our review of the record on appeal, we conclude that the district court did not err in denying the petition as procedurally barred. Appellants unspecified mental health issues and lack of legal knowledge are not impediments external to the defense, and thus, they do not provide good cause. Phelps v. Director, 104 Nev. 656, 660, 764 P.2d 1303, 1306 (1988). Appellants claims of ineffective assistance of trial and appellate counsel likewise do not provide good cause because those claims themselves are procedurally barred. Hathaway, 119 Nev. at 252, 71 P.3d at 506. Appellants claim of alleged judicial misconduct could have been raised in a timely petition, and he has not provided any explanation for his failure to do so. And this court has rejected equitable tolling because the plain language of NRS 34.726 requires appellant to demonstrate good cause to excuse a late petition. Brown v. McDaniel, 130 Nev. 565, 575-76, 331 P.3d 867, 874 (2014). Accordingly, we
ORDER the judgment of the district court AFFIRMED.
