Petitioner, ORDER

v. DEATH PENALTY CASE

Ryan Thornell, et al.,

Respondents. Before the Court is Petitioner Derek Don Chappell’s contested motion to alter or amend the Court’s Judgment denying him a writ of habeas corpus (the writ). (Doc. 141.) The motion is fully briefed. (Docs. 144, 154, 157.) For the reasons below, the Court will deny the motion. Between 2006 and 2007, Chappell stood trial for his alleged child-abuse and first- degree murder of a toddler. (R.O.A. 385–86.) A jury found him guilty as charged and sentenced him to death for the murder.1 (R.O.A. 533.) On direct appeal, the Arizona Supreme Court affirmed (3/1/11 Mandate), and Chappell sought relief on state postconviction review (PCR) (Doc. 42-3, Ex. WWW).

1 An Arizona capital trial has three contingent parts: the guilt phase, where a jury decides whether to convict the accused for first-degree murder, Arizona Revised Statutes (A.R.S.) § 13-703(D) (2007); the aggravation phase, where the jury decides whether there is an aggravating circumstance, making the accused eligible for a death sentence, A.R.S. § 13- 703.01(C) (2007); and the penalty phase, where the jury weighs the aggravators and mitigators and decides whether to impose that sentence, A.R.S. § 13-703(E) (2007). In his PCR petition, he claimed that at the trial’s penalty phase, his counsel had rendered ineffective assistance by not amply investigating or presenting, as mitigation, evidence of his mental-health issues. (Id. at 21–36.) He also claimed that there was newly- discovered, neurological evidence of his brain damage that would have caused a sentence less than death, had it been offered at the penalty phase. (Id. at 36–38.) He did not allege that his counsel had rendered ineffective assistance by not offering it. (Id. at 21–38.) In its response, the State asked the PCR court to treat the new-evidence claim not only as raised by Chappell, but also as an ineffective-assistance-of-trial-counsel (IAC) claim. (Doc. 56- 6, Ex. RRRR at 73.) Chappell, in his reply, backed the State’s request and raised the brain- damage IAC claim for the first time. (Doc. 69-5, Ex. IIIII at 44–45.) In Arizona, claims raised for the first time in a reply are waived. State v. Lopez, 221 P.3d 1052, 1053–54, ¶¶ 3–7 (Ariz. Ct. App. 2009). Consistent with this rule, the PCR court expressly considered only the claims raised in the PCR petition and then denied the merits of the petition’s un-precluded claims. (Doc. 70-2, Ex. OOOOO at 1–3.) It considered the mental-health IAC and new-evidence claims, but not the brain-damage IAC claim, and denied the former two on the merits. (Id.) Chappell petitioned to have the Arizona Supreme Court review the denial of the mental-health IAC claim but did not raise the brain-damage IAC claim or cite any evidence of brain damage. (Doc. 72-3, Ex. HHHHHH.) The Arizona Supreme Court denied review. (Doc. 72-6, Ex. KKKKKK.) In 2015, after he was denied relief in state court, Chappell noticed his intent to file a petition for the writ in this Court. (Doc. 1.) The Court issued an order to receive the state- court record from the state’s Supreme Court and to “encourage the parties to file any additional parts of the state[-]court record that the parties believe[d were] relevant to resolving allegations” in the parties’ briefs. (Doc. 6 at 5.) Later on, the Court received the record, and Chappell filed the writ petition. (Docs. 8 and 25.) In Claim 2(A)(2) of the petition, he argued guilt-phase IAC based on counsel’s alleged failure to investigate or present “expert medical evidence” to rebut the child-abuse evidence that Chappell had caused petechiae on the boy’s neck by strangling him. (Id. at 79–84.) Claim 2(C)(1) raised the brain-damage IAC claim. (Id. at 93–105.) The parties agreed that Claims 2(A)(2) and (C)(1) had not been raised in state court and thus were procedurally defaulted in this Court. (Id. at 79, 93; Doc. 33 at 62, 93.) Chappell asked the Court to excuse the default, alleging that his prior PCR counsel had rendered ineffective assistance by not raising them. (Doc. 25 at 79, 93.) In December 2023, after the parties briefed the petition and while the petition remained pending, Chappell returned to state court, noticed a new request for PCR relief, and disclosed the notice to this Court. (Doc. 127-1.) He also disclosed his intent to raise the petechiae and brain-damage IAC claims in the new PCR case. (Doc. 127 at 6.) In January 2024, he filed a PCR petition raising both those claims (Doc. 144 at 8–76) and arguing that his prior PCR counsel had rendered ineffective assistance by not raising them (id. at 76–83). By May 2024, Chappell had disclosed the reply in support of the 2024 PCR petition and a 2024 PCR-court stay order. (Doc. 134-1 at 2; Doc. 137-1 at 2–42.) He had not disclosed the petition itself. The PCR court later lifted the stay, and in October 2024, denied the petition. (Doc. 144 at 86–96.) First, the court barred both IAC claims under State v. Spreitz, 39 P.3d 525, 526, ¶ 4 (Ariz. 2002), and Stewart v. Smith, 46 P.3d 1067, 1071, ¶ 12 (Ariz. 2002). In Spreitz, the Arizona Supreme Court noted that under then-Rule 32.2(a)(3) of the Arizona Rules of Criminal Procedure, IAC claims are “waived and precluded” on successive PCR when they “could have” been, but were not, raised in a prior PCR petition. 39 P.3d at 526, ¶ 4 (citing State v. Conner, 786 P.2d 948, 951 (Ariz. 1990)). The rule’s drafters commented that under Rule 32.2(a)(3), certain claims could be “deemed waived without considering the defendant’s personal knowledge, unless such knowledge [was] specifically required to waive the constitutional right involved.” Ariz. R. Crim. P. 32.2 cmt. to 1995 amend. In Smith, the Arizona Supreme Court noted that Rule 32.2(a)(3)’s waiver exception did not apply to IAC claims raised for the first time in a successive PCR, when an IAC claim was raised in a prior PCR. See Smith, 46 P.3d at 1071, ¶ 12. The Arizona Court of Appeals enforced this per se bar in State v. Traverso, 537 P.3d 345, 347–49, ¶¶ 9–13 (Ariz. Ct. App. 2023), vacated in part by 576 P.3d 97 (2025), and the PCR court applied the bar to Chappell’s petechiae and brain-damage IAC claims (Doc. 144 at 86–96). Afterward, Traverso filed a petition for review (PFR) to the Arizona Supreme Court. Traverso, 576 P.3d at 102, ¶ 18. The pending PFR in Traverso did not persuade the PCR court to not bar Chappell’s petechiae or brain-damage IAC claims. (Id. at 94.) The court found it “entirely speculative” that the petition for review’s outcome in Traverso would favor Chappell. (Id.) It further found that if the Arizona Supreme Court granted review and removed the per se bar, Rule 32.2(a)(3) still barred both claims. (Id.) The court also denied the merits of the petechiae IAC claim. (Id. at 91.) But under Rule 32.2(a)(2), it did not reach the merits of the brain-damage IAC claim. (Id. at 95–96.) Rule 32.2(a)(2) bars claims previously and “finally adjudicated on the merits.” Ariz. R. Crim. P. 32.2(a)(2). The court found that on prior PCR, the brain-damage IAC claim’s “factual basis” was resolved “on the merits”—either through the denial of the mental- health IAC, or the new-evidence, claims. (Doc. 144 at 91.) Last, the court rejected the PCR- counsel claim, as Chappell had no right to such counsel. (Id. at 94–96.) Chappell petitioned to have the Arizona Supreme Court review the denial of the petechiae and brain-damage IAC claims. (Id., Ex. D.) While Chappell’s PFR and wri
