habeas corpus under 28 U.S.C. § 2254. The district court certified four issues in this appeal, one of which we addressed in a concurrently filed published opinion. We address Cook’s remaining claims here and affirm the district court’s denial of
habeas relief on each of those issues. 1
1. First, Cook claim s that the prosecution and police “engaged in an egregious and pervasive pattern” of misconduct with regard to his investigation and trial, which resulted in a prejudicial violation of his constitutional rights. Cook
raise d a plethora of misconduct claims in his state and federal habeas petition s but , in his appeal to this court , focuses on his claim s that “the prosecution and its agents engaged in flagrant misconduct by threatening and coercing multiple witnesses into testifying against Cook, offering undisclose d inducements in exchange for testimony against Cook, and suppressing crucial impeachment evidence.” On habeas review, the California Supreme Court held that Cook’s allegations of prosecutorial misconduct were “procedurally barred because most of the alleg ed acts of misconduct were not challenged on appeal,” citing Ex parte
Dixon , 264 P.2d 513, 514 (Cal. 1953), “and the remaining acts were raised and rejected on appeal,” citing In re Waltreus , 397 P.2d 1001, 1005 (Cal. 1965) (In Bank)

. In the alternative , it also denied each of Cook’s claims on the merits

.

1 Because the parties are familiar with the underlying facts and issues in this case, we do not recount them at length here.3

California’s Dixon bar has been upheld as an adequate and independent procedural ground capable of barring federal habeas review, see Johnson v. Lee , 136 S. Ct. 1802, 180 6 (2016) , but the Waltreus bar has not, see Ylst v. Nunnemaker , 501 U.S. 797, 805 (1991). Thus, we conclude that the California Supreme Court’s Dixon bar precludes federal habeas review over the claims of
state misconduct that Cook could have raised on appeal , but did not

. 2 Because Cook fails to show cause and prejudice for excusing his procedural default on these claims, we dec line to re ach them on the merits.
As to the remaining allegations of state misconduct that Cook did previously raise in his direct appeal , we conclude that they are not barred from federal review
based on Waltreus and thus review them on the merits. In doing so, we look to the California Supreme Court opinion on direct review as the “last reasoned state

- court decision” in determining whether federal habeas relief is warranted on the merits
of these claims

. Van Lyn n v. Farmon , 347 F.3d 735 , 738 (9th Cir. 2003) (citing Franklin v. Johnson , 290 F.3d 1223, 1233 n. 3 ( 9th Cir. 2002)). Generally, the

2 The district court concluded that the Dixon rule did not bar Cook’s pros ecutorial misconduct claim s because “[t]he California Supreme Court did not specify which acts of misconduct had not been challenged on appeal, nor does the record clarify this point.” But a comparison of the state misconduct claims that Cook r aised on ap peal with the claims he raised in his state habeas petition clarifies which allegations were previously raised and rejected by the California Supreme Court on direct review (and barred by the state habeas court under Waltreus ), and which were not (and barred under Dixon ).4

misconduct claims that were raised and addressed on direct review are : (1) the alleged discovery violations as to the fo ur witnesses mentioned in the state habeas decision; (2) the alleged failure to preserve Sadler’s footprint evidence and photographs of the occupants at 2250 Menalto; (3) the alleged prosecutorial vouching for government witnesses through Detective Sabin’s testimony ; (4) the alleged improper use of leading questions by the prosecution; and (5) the improper comments during both the prosecutor’s opening and closing arguments. We conclude that the California Supreme Court’s decision on appeal provided

reason a ble bas e s for its rejection of each of these claims on the ground s that the alleged misconduct did not rise to the level of error , did not prejudice Cook, or
both. See People v. Cook , 139 P.3d 492 (Cal. 2006). As such, we deny fed e ral
habeas relief for Cook’s claims of state misconduct.
2. Second, Cook asserts that he was deprived of the effective assistance of counsel during the guilt phase of his trial . According to Cook, his trial counsel
were ineffective due to their: (1) failure to inve stigate whether Cook knowingly and intelligently waived his Miranda rights, and whether his statement was coerced; (2) withdrawal of the motion to suppress in exchange for suppression of another statement that was already inadmissible; (3) trial strategy a round conceding guilt for the Bettencourt murder, which led to vouching for recanting witnesses and failing to investigate ballistics evidence; and (4) failure to5

investigate an insanity defense and to argue that Cook lacked the requisite mens
rea because of his mental illness. To prevail on his ineffective assistance of counsel claim, Cook must show
that his trial counsel’s conduct fell below an objective standard of reasonableness,
and that he was prejudiced by his counsel’s acts or omissions. Strickland v. Washington , 466 U.S. 668 (1984)

. Judicial review of a Strickland claim is “highly deferential,” and “doubly deferential when it is conducted through the lens of federal habeas.” Yarborough v. Gentry , 540 U.S. 1, 6 (2003) (per curiam). “When § 2254(d ) applies, the question is not whether counsel’s actions were reasonable. The question is whether there is any reasonable argument that counsel satisfied Strickland ’s deferential standard.” Harrington v. R ichter , 562 U.S. 86, 10 5 (2011)

. Given the standard of review, we conclude that Cook has not carried his burden of showing that the California Supreme C ourt lacked any reasonable basis

to deny his ineffective assistance of counsel claims. On this record, a reasonable basis may exist on w hich the California Supreme Court could conclude that Cook’s trial counsel performed adequately or that Cook suffered no prejudice from the alleged deficiencies

. See Strickland , 466 U.S. at 668; Cullen v. Pinholster , 563 U.S. 170 (2011). 3. Finally, Cook claim s that cumulative trial error resulted in a deprivation of his constitutional rights. “C umulative error applies where, ‘although no single6

trial error examined in isolation is sufficiently prejudicial to warrant reversal, the
cumulative effect of mu ltiple errors [has] still prejudice [ d ] a defendant.’” Whelchel v. Washington , 232 F.3d 1197, 1212 (9th Cir. 2000) ( quoting United States v.
Frederick , 78 F.3d 1370, 1381 (9th Cir. 1996). “ We have granted habeas relief
under the cumulative effects doctrine when there is a ‘unique symmetry’ of otherwise harmless errors, such that they amplify each other in relation to a key contested issue in the case.” Ybarra v. McDaniel , 656 F.3d 984, 1001 (9th Cir. 2011) ( quoting Parle v. Runnels , 505 F.3d 922, 933 (9th Cir. 2007)). The cumulative impact of the errors must, however, render the trial and sentencing “fundamentally unfair.” Id

. (quoting Parle , 505 F.3d at 927). Where “no error of constitutional magnitude occurred, no cumulative pr ejudice is possible.” Hayes v. Ayers , 632 F.3d 500 , 524 (9th Cir. 2011) (citi ng United States v. Larson , 460 F.3d 1200, 1217 (9th Cir. 2006) ).
T he California Supreme Court had a reasonable basis for finding that no
error occurred with regard to each of Coo k’s habeas claims

. W ithout any findings of error, the state habeas court could not have found cumulative prejudice.
Because there is a reasonable basis for concluding that the cumulative effect of Cook’s alleged errors did not render his trial “fundament ally unfair,” and Cook has
not shown otherwise , we deny relief on this claim. The district court’s denial of Cook’s habeas petition is AFFIRMED.
