Two years ago, the Supreme Court reversed a judgment of this court where we had failed to give the proper deference owed to a state-court habeas decision under the Antiterrorism and Effective Death Penalty Act (“AEDPA”), 28 U.S.C. § 2254. See Davis v. Ayala, — U.S. —, 135 S.Ct. 2187, 2208, 192 L.Ed.2d 323 (2015). Last year, we followed Davis in upholding a state-court decision where “its invocation of the Strickland prejudice standard might have been ambiguous but was not clearly incorrect.” Mann v. Ryan, 828 F.3d 1143, 1157 (9th Cir. 2016) (en banc). The panel’s decision departs from the instruction of Davis and its implementation in Mann. This case ought to have been reheard en banc for two reasons.
First, a divided panel of this court found that a unanimous California Supreme Court decision by Justice Werdegar applied an incorrect standard to determine whether habeas petitioner James Edward Hardy (“Hardy”) was prejudiced by the undisputed ineffective assistance of trial counsel. The panel majority got there by out-of-context “fly-specking” some of that court’s language, and denigrating other language that clearly stated its use of the proper standard.
Second, perhaps recognizing the weakness of its argument that the California Supreme Court had applied the wrong standard, the panel majority pivoted to its secondary argument that, assuming the state court had applied the correct standard, its application of that standard was unreasonable. The state court had determined that Hardy was not prejudiced by the ineffective assistance of counsel because the state produced ample evidence that Hardy conspired to kill the victims to obtain life insurance proceeds and aided and abetted the commission of the murders. In deciding that the California Supreme Court’s conclusion was based on' unreason, rather than the compelling evidence in the record, the majority simply abandoned any notion of the proper deference owed to a state court’s judgment under AEDPA.
Both of the majority’s determinations are contrary to repeated Supreme Court instructions to us as to how we must treat state-court decisions in our interpretation and application of AEDPA. I respectfully dissent from our refusal to rehear this case en banc.
I. Factual and Procedural History
The background of this case is important for appreciating how far the majority exceeded the limited scope of its review under AEDPA. Clifford Morgan (“Morgan”) devised a plan to have his wife and son killed so he could collect on their life insurance policies. In re Hardy, 41 Cal.4th 977, 63 Cal.Rptr.3d 845, 163 P.3d 853, 860 (2007). He enlisted Mark Anthony Reilly (“Reilly”) to help with the plan. Id. Reilly at first failed to recruit Calvin Boyd (“Boyd”) to participate in the murders. Id. According to the state, Reilly then recruited appellant Hardy to help commit the murders. Id. Sometime in the night of May 20-21, 1981, multiple assailants went to Morgan’s home, cut a chain lock with bolt cutters, and stabbed Morgan’s wife and son to death. Id.
Hardy, Reilly, and Morgan were tried together in Los Angeles County Superior Court. Id., 63 Cal.Rptr.3d 845, 163 P.3d at 862. Hardy was represented by Los Ange-les County Deputy Public Defender Michael Demby (“Demby”). Id. Hardy and Reilly were convicted of two counts of first *808degree murder, one count of conspiracy to commit murder to collect life insurance proceeds, and several special-circumstance allegations.1 Id., 63 Cal.Rptr.3d 845, 163 P.3d at 863. In the penalty phase, Hardy and Reilly were both sentenced to death. Id., 63 Cal.Rptr.3d 845, 163 P.3d at 859.
Hardy filed a habeas petition in the California Supreme Court, alleging ineffective assistance of counsel by Demby and requesting relief as to the penalty phase. Id., 63 Cal.Rptr.3d 845, 163 P.3d at 863. The California Supreme Court ordered the state to show cause why Hardy was not entitled to penalty phase relief because Demby had failed to call available mitigation witnesses. Id., 63 Cal.Rptr.3d 845, 163 P.3d at 864. Upon the California Supreme Court’s order, a referee heard evidence that incriminated Boyd in the murders (the “Boyd evidence”). See id., 63 Cal. Rptr.3d 845, 163 P.3d at 867-81. The referee entered findings of fact and conclusions of law, which found Demby performed de-ficiently when he failed to investigate and present evidence that Boyd had done the stabbing and was the actual killer. See id., 63 Cal.Rptr.3d 845, 163 P.3d at 864, 885. Based on the factual findings in the referee’s report, Hardy filed a second petition for a writ of habeas corpus arguing that evidence from that hearing also required guilt-phase relief. Id., 63 Cal.Rptr.3d 845, 163 P.3d at 859.
The California Supreme Court consolidated Hardy’s petitions for penalty-phase and guilt-phase relief. Id. In a unanimous opinion authored by Justice Werdegar, the court granted Hardy’s petition to vacate the judgment of the penalty phase. Id., 63 Cal.Rptr.3d 845,- 163 P.3d at 895. For his guilt-phase relief petition, the California Supreme Court agreed with Hardy that Demby’s performance was constitutionally deficient under the Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984), standard. See In re Hardy, 63 Cal.Rptr.3d 845, 163 P.3d at 884-85. However, the court also found that Hardy did not suffer prejudice therefrom in the guilt phase. Id., 63 Cal.Rptr.3d 845, 163 P.3d at 891. The court reasoned that, even though the Boyd evidence may have cast doubt on Hardy’s role as the killer who stabbed the victims to death, there had been ample evidence at trial to convict Hardy of first degree murder on a conspiracy theory, id., 63 Cal.Rptr.3d 845, 163 P.3d at 888-90, and on an aiding-and-abetting theory, id., 63 Cal.Rptr.3d 845, 163 P.3d at 890-91. As the court stated,
After weighing this evidence and considering what, petitioner’s trial would have looked like had he been represented by competent counsel, we conclude that although there is a reasonable probability the jury would not have convicted petitioner on the prosecution’s proffered theory that he was the actual killer, ample evidence remains that petitioner was guilty of the murders on the alternative theories that he conspired with, and aided and abetted, Reilly, Morgan and others to commit the murders.
Id., 63 Cal.Rptr.3d 845, 163 P.3d at 891 (citation omitted).2
*809Hardy then filed a habeas petition in the United States District Court for the Central District of California. A magistrate judge issued a report and recommendation denying Hardy’s claims. Hardy v. Martel, 2013 WL 3223392 at *1 (C.D. Cal. June 24, 2013). The district court accepted the report, entered judgment denying the petition, and issued a certificate of appealability as to “[wjhether the state supreme court reasonably concluded that Hardy was not prejudiced as a result of his counsel’s failure to uncover and expose the fact that a key government witness, Calvin Boyd, was probably the person who committed the murders.” Id. (alteration in original).
A majority of the panel voted to reverse the district court’s judgment. The majority held that the California Supreme Court had applied a standard contrary to clearly established law in analyzing Strickland prejudice because the opinion uses the words “substantial evidence” at certain points in describing the evidence in the record.3 Analyzing Hardy’s Strickland claim de novo, the panel held that Hardy was prejudiced in the guilt phase by Dem-by’s deficient performance. In the alternative, assuming the California Supreme Court applied the correct standard, the majority held that Justice Werdegar’s application of the Strickland prejudice prong was unreasonable.
II. Justice Werdegar Applied the Correct Prejudice Standard
The majority’s claim that Justice Werde-gar used an incorrect standard — that she weighed evidence to see whether it constituted “substantial evidence” to determine whether prejudice as defined by Strickland existed — is inconsistent with her language elsewhere and her methodology throughout the opinion. She properly applied Strickland’s reasonable probability standard to determine whether prejudice resulted from the ineffective assistance of counsel in failing to investigate and to properly cross-examine Boyd.
First, she unquestionably stated the proper, Strickland prejudice standard and the majority opinion so recognized:
Second, he must ■ also show prejudice flowing from counsel’s performance or lack thereof. Prejudice is shown when there is a “reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different. A reasonable probability is a probability sufficient to undermine confidence in the outcome.”
In re Hardy, 63 Cal.Rptr.3d 845, 163 P.3d at 883-84 (emphasis added) (citations omitted) (quoting In re Avena, 12 Cal.4th 694, 49 Cal.Rptr.2d 413, 909 P.2d 1017, 1032-33 (1996)); see also Strickland, 466 U.S. at 694, 104 S.Ct. 2052 (“A reasonable probability is a probability sufficient to undermine confidence in the outcome.”).
She then started her analysis of whether Hardy had proved prejudice by correctly explaining the three relevant elements of the Strickland prejudice analysis in the particular context of Demby’s deficient performance.
(1) What evidence was available that counsel failed reasonably to discover?
(2) How strong was that evidence?
(3) How strong was the evidence of guilt produced at trial?
As to the first element, she found in favor of Hardy: “Subtracting Boyd’s testimony, *810the evidence that petitioner was the actual killer was weak and circumstantial.” Id., 63 Cal.Rptr.3d 845, 163 P.3d at 886. She also found in favor of Hardy as to the second element. Properly presented, the Boyd evidence would have shown that “the evidence that petitioner committed the murders was much weaker,” so that there was a reasonable probability the jury would not have convicted him as the actual killer of the two Morgans. Id., 63 Cal.Rptr.3d 845, 163 P.3d at 890.
But as to the third element, the evidence of guilt on the alternative theories of (1) conspiring to commit the murders and (2) aiding and abetting the commission of the murders, the evidence was indeed strong and was not undermined by Boyd’s testimony. “[H]e [petitioner] was strongly linked to the conspiracy.” Id. (emphasis added). Justice Werdegar provided a detailed discussion of the linkage:
“According to Debbie Sportsman [the then-girlfriend of Reilly, the codefendant on the murder charges], Reilly began associating with Hardy around May 10, 1981. She testified that the two men had many private, conversations during this period and often drank and took drugs together. On the evening of May 20, 1981, the night of the killings, Debbie met with Hardy and Reilly at thé latter’s apartment. Reilly spoke with Morgan on the telephone and asked him if he wanted to go through with the killing. Morgan, who was in Carson City, answered that he did.” Petitioner thereafter discussed his alibi with Colette Mitchell [Hardy’s then-girlfriend] “all the time,” and he coordinated his alibi with Reilly as well. According to Colette, petitioner knew several details about the crimes, including that the assailants had used a tool to cut the chain lock, that life insurance proceeds were the reason for the killing, that the money was collecting interest, and that Reilly was in charge. Most incriminating was petitioner’s receipt of $1,000 in $100 bills after the murders, his instruction to Colette to dispose of his shoes on learning that police might have discovered some footprints at the crime scene, and his direction to dispose of the M-l carbine rifle allegedly stolen from the Morgan home. Even discounting petitioner’s inconsistent statements to Colette about whether he had participated in the actual killing, there is ample evidence showing he participated in the plan to kill the victims as part of a wider conspiracy to defraud the insurance companies.
Id. (emphasis added) (citation omitted) (quoting People v. Hardy, 2 Cal.4th 86, 5 Cal.Rptr.2d 796, 825 P.2d 781, 796 (1992)). Justice Werdegar relied on this ample evidence 4 of Hardy’s role in the conspiracy, in contradistinction to the weak evidence that he was the actual stabber, in concluding that Demby’s deficient performance did not prejudice Hardy as to the verdict of guilt.
Her conclusion is reasonable if one considers what the evidence of Boyd’s perfidy — left on the cutting room floor by trial counsel — accomplished. That evidence showed that Hardy did not wield the knife, Boyd did. But the evidence unearthed about Boyd did nothing to rebut the evidence of Hardy’s participation in the conspiracy and his aiding and abetting. As Justice Werdegar fulsomely relates, “such deficient representation nevertheless does not require reversal of the guilt judgment because counsel’s failure to investigate did *811not undermine the prosecution’s theory that petitioner conspired to commit the murders, and such conspiracy rendered petitioner liable for first degree murder irrespective of the possibility that a third party actually killed the victims.” Id., 63 Cal.Rptr.3d 845, 163 P.3d at 859-60 (bold-ed emphasis added). And again,
But this [Boyd] evidence does not undermine5 other critical evidence, such as the testimony of Colette Mitchell, who testified petitioner told her he was going to steal something from someone to enable the collection of insurance proceeds;6 that he had been to the victims’ home the night of the murders; that he knew the crime was to be accomplished by cutting the chain on the door; that he received $1,000, apparently for his participation in either the conspiracy or the murders themselves; that Morgan was not worried about the delay the trial caused because his money was earning interest while he was in jail; or that people who said the murder was committed by more than one person were wrong because he “[knew] for a fact it was one.” The referee’s findings also do not fatally undermine Colette’s testimony regarding petitioner’s suspicious instructions to her to help dispose of both the stolen M-l carbine rifle and his shoes. That petitioner went to the victims’ home with Reilly and Boyd is also' possible. In short, although the weight and breadth of the evidence showing Boyd participated in the murders is disturbing, such evidence does not fatally undermine the prosecution’s entire case against petitioner.
Id., 63 Cal.Rptr.3d 845, 163 P.3d at 883 (alteration in original) (bolded emphasis added). It was the fact that the Boyd evidence did not undermine the conspiracy and aiding-and-abetting convictions— not that the conspiracy and aiding-and-abetting evidence was “substantial”— which drove the state court’s decision that there was no prejudice under the Strickland “undermining” test for prejudice. “Undermine confidence in the outcome” is the proper Strickland test and the one used by Justice Werdegar, as shown by her repeated use of the term , “undermine” when weighing the evidence. Moreover, the California Supreme Court quite clearly applied the correct Strickland standard when it concluded its prejudice analysis:
Because petitioner would have been convicted of two first degree murders on these two theories of derivative liability irrespective of Demby’s unreasonable failure to investigate and present evidence of the Boyd connection, petitioner fails to demonstrate he would have achieved a more favorable outcome at the guilt phase had Demby competently investigated the Boyd connection. Accordingly, we conclude petitioner fails to demonstrate prejudice at the guilt phase flowing from Demby’s deficient representation.
Id., 63 Cal.Rptr.3d 845, 163 P.3d at 891 (citing Strickland, 466 U.S. at 687-88, 104 5.Ct. 2052).
As Judge Callahan noted in dissent, we recently reaffirmed that, in habeas cases, when “it is possible to read the state court’s decision in a way that comports with clearly established federal law ... we *812must do so.” Hardy, 832 F.3d at 1144 (Callahan, J. dissenting) (alterations in original) (quoting Mann, 828 F.3d at 1157-58). We follow this approach because the Supreme Court has made clear that “[a] readiness to attribute error is inconsistent with the presumption that state courts know and follow the law. It is also incompatible with § 2254(d)’s ‘highly deferential standard for evaluating state-court rulings,’ which demands that state-court decisions be given the benefit of the doubt.” Woodford v. Visciotti, 537 U.S. 19, 24, 123 S.Ct. 357, 154 L.Ed.2d 279 (2002) (per curiam) (citations omitted) (quoting Lindh v. Murphy, 521 U.S. 320, 333 n.7, 117 S.Ct. 2059, 138 L.Ed.2d 481 (1997)).
This is not a case where we really need to give the California Supreme Court “the benefit of the doubt.” But instead of following the Supreme Court’s clear instructions, the majority went out of its way to find fault with the opinion. Ignoring Justice Werdegar’s careful reasoning for finding no prejudice, the majority focused exclusively on the opinion’s use of the term “substantial evidence.” According to the majority, Justice Werdegar applied a “substantial evidence” standard to determine that Hardy suffered no prejudice from Demby’s performance.
But Justice Werdegar was not weighing the evidence by a “substantial evidence” standard. Instead, she used the term “substantial evidence” six times to explain that extensive and compelling evidence supported the prosecution’s theory that Hardy was guilty of murder because he conspired with, and aided and abetted, others to commit the murders. She characterized this derivative liability evidence as “substantial” in contradistinction to her assessment that the evidence that Hardy was the actual stabber was weak and undermined by the Boyd evidence.7 As noted above, she also stated that this derivative liability evidence was “ample.” The majority’s assertion that Justice Werdegar’s opinion weighed the critical evidence related above by whether it was “substantial” rather than whether this evidence precluded a reasonable probability of a different result is not a fair reading of the opinion.
III. Justice Werdegar’s Application of the Strickland Prejudice Standard Was Reasonable
Perhaps recognizing the weakness of its argument that the California Supreme Court applied the incorrect standard, the majority equivocated and suggested that, even if the California Supreme Court had applied the correct standard, its application of that standard was unreasonable. According to the majority, if Demby had presented the Boyd evidence, the prosecution’s theory that Hardy was the actual stabber would have been undermined. Therefore, in the majority’s estimation, this reasonable doubt as to Hardy’s role as the actual stabber would have also changed the jury’s view of Hardy’s guilt as a co-conspirator and as an aider and abettor of the murders.
But the majority’s eagerness to find that the California Supreme Court opinion was an unreasonable application of the Strickland prejudice standard also conflicts with established Supreme Court precedent. In Harrington v. Richter, 562 U.S. 86, 131 S.Ct. 770, 178 L.Ed.2d 624 (2011), this *813court had granted a habeas petition after trial counsel for the petitioner failed to present expert testimony on blood evidence that would have bolstered the petitioner’s theory of the case. Id. at 97, 131 S.Ct. 770. The Supreme Court reversed and noted that the petitioner had not established Strickland prejudice because “[t]here was ample basis for the California Supreme Court to think any real possibility of Richter’s being acquitted was eclipsed by the remaining evidence pointing to guilt.” Id. at 113, 131 S.Ct. 770.
As explained above, Justice Werdegar did not abuse the broad discretion established by AEDPA in finding that the compelling evidence of conspiracy and aiding- and-abetting guilt precluded a finding of Strickland prejudice. That evidence was both “substantial” and “ample.” The girlfriends of Hardy and Reilly at the time, Collette Mitchell and Debbie Sportsman respectively, testified to Hardy’s close association with Reilly in the weeks leading up to the murder. Sportsman testified that Hardy was with Reilly when Reilly spoke on the phone with Morgan and Morgan confirmed he wanted the killings to happen. Mitchell testified that Hardy had detailed knowledge of'the crime’s execution, that Hardy received money for his role in the murders, and that Hardy tried to dispose of physical evidence linking him to the crime scene. Even if we would reach a different conclusion as to whether Hardy was prejudiced by Demby’s performance, it was not unreasonable for Justice Werde-gar to conclude that — correctly applying the Strickland prejudice standard — this highly incriminating evidence precluded a reasonable probability of a different jury verdict. The panel majority failed to appreciate this essential point when it decided that its interpretation of the paper record was the only reasonable conclusion.
IV. Conclusion
The Supreme Court has repeatedly admonished this court that it should not reverse reasonable state-court decisions on habeas review. The majority nit-picked a unanimous opinion that repeatedly quoted Strickland in order to conclude that the California Supreme Court did not apply the long-settled and well-known prejudice standard for ineffective-assistance-of-counsel cases. The majority also decided that, if the California Supreme Court in fact applied what it said it was applying, then the California Supreme Court acted unreasonably by not accurately imagining how the jury would have reacted to the Boyd evidence. The majority’s unacknowledged reinterpretation of AEDPA deference is in conflict with precedents of the Supreme Court and this court.
I respectfully dissent from our failure to rehear this case en banc.
OPINION
BASTIAN, District Judge:During the night of May 20, 1981, someone entered the home of Clifford and Nancy Morgan and brutally stabbed Nancy Morgan and their eight-year-old son to death. According to the State of California, that someone was James Edward Hardy. The State argued that theory at trial, obtaining a conviction and death sentence for Hardy. As it turns out, that someone was likely Calvin Boyd, a key prosecution witness at Hardy’s trial. Yet Hardy remains imprisoned, serving a life sentence.
The Antiterrorism and Effective Death Penalty Act of 1996 (“AEDPA”) raised the standard of review for petitioners, greatly limiting the success rate of petitions for writs of habeas corpus.1 Despite the de*814manding standard set by AEDPA for state inmates, this case does not present a close question — Hardy is entitled to a writ of habeas corpus pursuant to 28 U.S.C. § -2254.
Factual and Procedural History2
Clifford Morgan (hereinafter “Morgan”) lived in a home on Saticoy Street in Van Nuys, California, with his wife, Nancy, and their eight-year-old son. Morgan devised a sinister plan to have his wife and son killed so he could collect on their life insurance policies. He enlisted the help of Mark Anthony Reilly. Reilly lived in an apartment complex on Vose Street in Van Nuys. Reilly agreed to Morgan’s plan and sought a partner for the murders. In exchange for this help, Morgan allowed Reilly to live in Morgan’s home and promised to allow Reilly to manage a bar that Morgan intended to open with the insurance proceeds.
After failing to recruit a kickboxer named Marc Costello, Reilly turned to another Vose Street resident, Calvin Boyd, and Boyd’s friend Marcus. According to Boyd’s trial testimony, Boyd eventually declined to participate in the murders because Reilly was unable to pay him with either money or cocaine in advance. According to the State, Reilly then tried to recruit Hardy, telling two friends that Hardy might assist him in the crime.
In May 1981, Morgan moved to Carson City, Nevada, ostensibly for business reasons but likely to establish an alibi. During the night of May 20 or morning of May 21, two people, allegedly Hardy and Reilly, used bolt cutters and a key to enter the Morgan residence. Nancy Morgan and her son were sleeping in a back bedroom. Both were stabbed to death. Experts testified that physical evidence suggested at least two persons were responsible for the slayings, which likely occurred between 3:30 and 5:30 a.m.
Michael Mitchell, Reilly’s roommate, testified that he returned to the Vose Street apartments and went to sleep, sometime after 11:00 p.m. on May 20, 1981. Around midnight, he awoke and saw Hardy, Reilly, Colette Mitchell (no relation to Michael Mitchell), and Steven Rice (another neighbor) in the apartment that he shared with Reilly. Later, he heard male voices and heard the shower being used. The next morning, he observed wet towels in the bathroom, but he saw no evidence of blood.
Shortly after the murders, Reilly admitted his guilt to his then-girlfriend Debbie Sportsman and made incriminating statements to her. He told Sportsman that Nancy Morgan said “[p]lease don’t kill me,” that more than one perpetrator was involved, that bolt cutters had been used to cut the chain lock on the door, and that a fish knife had been used in the stabbings.
Morgan’s recent purchase of an unusually large amount of life insurance raised suspicions, as did two incriminating statements he made to a neighbor — that his wife was worth more dead than alive, and that he expected she would die before him. Sportsman’s testimony linked Reilly to Morgan and human blood was found on Reilly’s shoes. No physical evidence was *815found that linked Hardy to .the murders; The evidence against Hardy consisted largely of the testimony of Calvin Boyd and Colette Mitchell.
Calvin Boyd was the State’s key witness. He testified that shortly after the murders, Reilly admitted that he and Hardy were the killers. Boyd stated Reilly had showed him recently purchased bolt cutters. Boyd claimed he walked through Rice’s apartment the morning of the murders and saw Reilly and Hardy both sleeping — placing the two men together shortly after the crime. Boyd also saw Rice and Colette Mitchell (hereinafter “Mitchell”) in the apartment.
Mitchell was Hardy’s girlfriend at the time of the murders but not at the time of trial. She gave testimony indirectly linking Hardy to the crime. Her initial statements to law enforcement provided Hardy with an alibi, but she changed her story and admitted to perjury. Mitchell contacted Hardy in jail intending to assist him even after she was granted immunity for her testimony. At trial, Mitchell testified she was working at a restaurant on the night of the murders. Hardy, Reilly, and Rice met at the restaurant shortly after 9:00 p.m. and Mitchell served them drinks. They went to the Vose Street apartments around 10:00 p.m. to “party” and use cocaine. Mitchell admitted to doing several large lines of cocaine and drinking at least three beers via a “beer bong.” Mitchell testified to quarreling with Hardy and leaving Reilly’s apartment to go next door. Sometime between midnight and 2:00 a.m., Rice and Mitchell left the apartments to purchase more beer. After returning, Hardy sought her out at Rice’s apartment and told her not to leave because he needed her that night. Despite having an unusually large amount of cocaine — which often would keep her awake — she passed out in Rice’s apartment and did not wake until 11:00 a.m. the next day. When she awoke, Hardy was asleep next to her and Reilly was asleep on a sofa.
Mitchell initially told police she had been with Hardy the entire night. At trial, she claimed she was either asleep or passed out for most of the night and did not know if Hardy left the apartment or not. Mitchell claimed Reilly once, told her that he and Hardy had left the apartment while she slept but that another time Reilly told her they had not left. Mitchell testified she and Hardy discussed his alibi “all the time.” Mitchell stated Hardy led her to believe he was going to steal something from someone to enable a third person to collect on an insurance policy. Hardy supposedly told her at least twice that he had been to the victims’ home on the night of the murders. Hardy claimed he knew the victims were alive when he was there because he heard them snoring. On another occasion, Hardy told Mitchell the victims had already been killed by the time he entered the home. Mitchell testified that Hardy said “we were at the house,” but she also stated that he told her “he didn’t do it.” Mitchell testified that Reilly admitted to her that he knew who the killer was and it was not Hardy.
Mitchell claimed Hardy said a chain on a door would be cut to give the crime the appearance of a robbery. According to Mitchell, Hardy was to receive a portion of $40,000 or $50,000, but he actually only received $1,000. Mitchell testified she, or someone else, put the $1,000 in a cedar box. Mitchell said Hardy made several other statements: Morgan was not worried about the trial because during the delay-his insurance proceeds were earning interest; the less she knew about the crime the better off she would be; Reilly was in charge of the situation; Hardy knew for a fact only one person committed the murders; Hardy took something from Mor*816gan’s home to make it look like a robbery; and the killers used bolt cutters. According to Mitchell’s testimony, Hardy asked her and Hardy’s brother to retrieve and dispose of an Ml carbine from Hardy’s apartment; a firearm of the same style was reported missing from the crime scene. Mitchell also testified that Hardy asked her to destroy some of his shoes after he learned police found a shoeprint at the scene.
At trial, Hardy’s attorney, Michael Dem-by, gave no opening statement and presented no evidence on Hardy’s behalf. The jury was instructed that individuals who directly and actively committed the act constituting the crime, those who aided or abetted the commission of the crime, and those who advised and encouraged its commission were equally guilty. An additional aid-and-abet instruction was also given.
Hardy, Reilly, and Morgan were convicted of two counts of first degree murder and one count of conspiracy to commit murder to collect life insurance proceeds. Six special circumstances were found by the jury. The defendants were not convicted on a burglary charge. A joint penalty phase was held for Hardy and Reilly— both were sentenced to death. Morgan died of cancer before he could be sentenced.
On appeal, the California Supreme Court vacated one of the special circumstances but affirmed the judgment in all other respects. The United States Supreme Court denied a petition for writ of certiorari. Hardy v. California, 506 U.S. 987, 113 S.Ct. 498, 121 L.Ed.2d 435 (1992).
On July 26, 1991, Hardy filed a petition for writ of habeas corpus in the California Supreme Court. That court issued an order to show cause why Hardy was not entitled to penalty phase relief because his trial counsel failed to call available mitigation witnesses. On April 28, 1993, the California Supreme Court ordered the Los Angeles County Superior Court to hold a reference hearing and make findings of fact.
The superior court judge heard evidence over several months in 1996 and 1997, where a very different story than the one presented at trial emerged. According to a number of credible witnesses, Boyd made very incriminating statements after the murders, Boyd’s alibi for the night of the murders was a sham, and Hardy had refused to participate in the crimes.3 On September 16, 1999, the superior court entered findings of fact and conclusions finding Demby performed deficiently when he failed to investigate and present evidence that (a) Calvin Boyd, a key prosecution witness, was the actual killer, and (b) the murders occurred at a time when Hardy could not have been present.
On May 3, 2000, Hardy filed his Supplemental Allegation to Conform the Pleadings to the Proof, arguing that evidence from the reference hearing also required guilt phase relief. The California Supreme Court issued an order directing the State to show cause why Hardy was not entitled to reversal of his conviction “because he is innocent of the capital crimes of which he was convicted, because a third party named Calvin Boyd committed the murders, and because [Hardy’s] trial counsel rendered constitutionally ineffective assistance of counsel by failing to present evidence demonstrating [Hardy’s] innocence.” *817Both of Hardy’s state habeas petitions were consolidated for argument and opinion.
On July 26, 2007, the California Supreme Court decided the consolidated petitions. Although that court recognized that the disturbing revelations about Boyd “presented a more difficult decision for the jury and may well have created in the minds of the jurors a reasonable doubt as to petitioner’s guilt,” it found Hardy could not meet the very difficult burden of an actual innocence claim. Hardy II, 41 Cal.4th at 1017-18, 68 Cal.Rptr.3d 845, 163 P.3d 853. As to ineffective assistance of counsel, the California Supreme Court granted Hardy’s claim that Demby’s performance was deficient at both the penalty and guilt phases of the trial. The court reversed Hardy’s death sentence but found Demby’s inadequate representation at the guilt phase did not prejudice Hardy because there was “substantial evidence” to convict him under an aid-and-abet or conspiracy theory. Id. at 1029-30, 63 Cal. Rptr.3d 845,163 P.3d at 862 (“We conclude substantial evidence supports the theory that petitioner was guilty of first degree murder on a conspiracy theory.”). The court also rejected Hardy’s actual innocence claim.
The California Supreme Court order specifically adopted several factual findings from the reference hearing, including: (1) Raynell Burney, Rickey Ginsburg, James Moss, Sandra Moss, Michael Small, and Steven Rice testified credibly regarding various incriminating statements and actions made by Boyd; (2) Boyd was not a credible witness; (3) Boyd habitually carried a knife similar to the murder weapon; (4) Boyd had previously committed several assaults with a knife; (5) Boyd had cuts on his hands after the killings; (6) Boyd’s alibi was false; (7) Boyd had motive to commit murder; (8) Boyd testified falsely when he stated at trial that the prosecutor had not promised him anything in- connection with his testimony when he was actually granted immunity; and (9) Boyd likely had a role in the murders, very possibly a primary one.
After the State chose not to retry the penalty phase, Hardy was resentenced to consecutive terms of life in prison without the possibility of parole. He was resen-tenced to twenty-five years to life on the conspiracy charge.
On September 6, 2011, Hardy timely filed a pro se petition for writ of habeas corpus in the United States District Court for the Central District of California. A magistrate judge ordered responsive briefing but denied Hardy’s request for appointment of counsel. On May 7, 2013, the magistrate issued a report and recommendation denying all claims. On June 24, 2013, the district court accepted the report and entered judgment denying the petition. The district court issued a certificate of appealability as to “[wjhether the state supreme court reasonably concluded that Hardy was not prejudiced as a result of his counsel’s failure to uncover and expose the fact that a key government witness, Calvin Boyd, was probably the person who committed the murders.” This appeal was timely filed.
Standards of Review
A district court’s decision to grant or deny a habeas corpus petition under 28 U.S.C. § 2254 is reviewed de novo. Brown v. Ornoski, 503 F.3d 1006, 1010 (9th Cir. 2007); Shumway v. Payne, 223 F.3d 982, 984 (9th Cir. 2000). Facts found by the district court are reviewed for clear error. Tapia v. Roe, 189 F.3d 1052, 1055 (9th Cir. 1999).
AEDPA applies because the petition was filed after the passage of that law. Jeffries v. Wood, 103 F.3d 827, 827 (9th Cir. 1996). *818Under AEDPA, relief may only be granted if the state court decision in question was either “contrary to, or involved an unreasonable application of, clearly established Federal law” or was “based on an unreasonable determination of the facts in light of the evidence presented in the State court proceeding.” § 2254(d)(l)-(2).
Analysis
The question now is whether the California Supreme Court decision was contrary to, or involved an unreasonable application of, clearly established federal law. The answer is yes; the California Supreme Court decision was contrary to established federal law. Alternatively, we also conclude that the California Supreme Court decision was an unreasonable application of clearly established federal law.
I.
The “clearly established federal law” for an ineffective assistance of counsel claim under the Sixth Amendment derives from Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052 (1984); see Cullen v. Pinholster, 563 U.S. 170, 189, 131 S.Ct. 1388, 179 L.Ed.2d 557 (2011) (“There is no dispute” that Strickland is clearly established federal law). Strickland established a two-part test: the defendant must show (1) counsel’s performance was deficient, and (2) the deficient performance prejudiced the defense. Strickland, 466 U.S. at 687, 104 S.Ct. 2052.
The first prong of Strickland is not contested here. The California Supreme Court concluded that Demby rendered deficient performance by failing to investigate and present evidence- that Boyd was likely the actual killer.4 Because neither party questions this conclusion, this Court need only review the findings under the second prong of Strickland, which the parties contest.
Under § 2254(d)(1), “contrary to” means “substantially different from the relevant precedent” of the Supreme Court. Williams v. Taylor, 529 U.S. 362, 405, 120 S.Ct. 1495, 146 L.Ed.2d 389 (2000). As an example, the Supreme Court explained that if a state court denied an ineffective assistance of counsel claim for failure to show prejudice by a preponderance of the evidence standard rather than by a reasonable probability of a different result standard, the state court’s ruling would be “contrary to” the clearly established federal law in Strickland because the state court would be applying a stricter standard. Id. 405-06, 120 S.Ct. 1495. This case presents a nearly identical set of circumstances.
The California Supreme Court held that Hardy did not demonstrate the level of prejudice required under Strickland. The court concluded that even without Boyd’s testimony, and even if Demby had proven to the jury that Boyd was the actual murderer, substantial evidence remained to permit a jury to find Hardy guilty of murder under an aid-and-abet or conspirator theory.
Although the California Supreme Court recited the Strickland standard, it concluded that because there was “substantial evidence” against Hardy he suffered no prejudice from Demby’s deficient performance. This was not the correct standard, and consequently, the relevant question re*819garding prejudice at the guilt phase was never properly addressed.
Substantial evidence is “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” 5 Richardson v. Perales, 402 U.S. 389, 401, 91 S.Ct. 1420, 28 L.Ed.2d 842 (1971) (quoting Consol. Edison Co. v. NLRB, 305 U.S. 197, 229, 59 S.Ct. 206, 83 L.Ed. 126 (1938)). By applying this standard, the state court created a much higher bar for Hardy than the law required. Under Strickland, the court must ask “whether there is a reasonable probability that, absent the errors [by counsel], the factfinder would have had a reasonable doubt respecting guilt.” 466 U.S. at 695, 104 S.Ct. 2052. A reasonable probability is “sufficient to undermine confidence in the outcome” and must be substantial, not just conceivable. Id. at 693-94, 104 S.Ct. 2052. This standard does not mean a petitioner must demonstrate “that counsel’s actions more likely than not altered the outcome.” Harrington v. Richter, 562 U.S. 86, 112, 131 S.Ct. 770 (2011) (citing Strickland, 466 U.S. at 693, 104 S.Ct. 2052) (internal quotation marks omitted). Requiring a habeas petitioner to demonstrate that had counsel performed adequately there would not have been sufficient evidence for a jury to convict is more akin to a Fed. R. Crim. P. 29 motion for a judgment of acquittal and has no place in the Strickland test. To the extent that the California Supreme Court found the Strickland prejudice prong was not met because substantial evidence remained to convict Hardy under a different theory, it applied a standard contrary to clearly established federal law.
This case differs substantially from Mann v. Ryan, 828 F.3d 1143 (9th Cir. 2016) (en banc). In Mann, this Court found that the state court’s opinion was ambiguous as to whether it was employing the proper Strickland standard. Id. at 1157. The most logical inference in Mann, however, was that the state court judge — who was also the original sentencing judge— applied the proper standard but recited the standard incorrectly. Hardy’s case presents the inverse. Here, the state court correctly recited the Strickland standard but then, in its application, abandoned it— replacing it with a substantial evidence standard. As the Supreme Court has made clear, it is the application, not the recitation of a standard .that matters for § 2254(d) purposes. See Sears v. Upton, 561 U.S. 945, 952, 130 S.Ct. 3259, 177 L.Ed.2d 1025 (2010) (per curiam) (“Although the Court appears to have stated the proper [Strickland ] prejudice standard, it did not correctly conceptualize how that standard applies to the circumstances of this case.”) (footnote omitted). It is apparent on the surface of the California Supreme Court’s decision that it applied an incorrect standard and no inferences need be, nor can be drawn, that could result in finding the state court applied the proper standard. See Mann, 828 F.3d at 1157.
Hardy’s petition satisfies the “contrary to” clause of § 2254(d)(1) because the California Supreme Court employed a standard of review which was significantly harsher than the clearly established test from Strickland. Id. (“Had the state post-conviction court applied [a stricter standard] to analyze [Petitioner’s] ineffective *820assistance of counsel claims, its opinion would have been contrary to clearly established federal law under AEDPA.”)- Because the state court used the wrong standard, we need not defer to that decision. See Panetti v. Quarterman, 551 U.S. 930, 948, 127 S.Ct. 2842, 168 L.Ed.2d 662 (2007) (explaining that when § 2254(d)(1) is satisfied, a court may review a petition “unencumbered by the deference AEDPA normally requires”). In other words, this Court may analyze Hardy’s constitutional claim de novo pursuant to § 2254(a). Frantz v. Hazey, 533 F.3d 724, 735-37 (9th Cir. 2008) (explaining the two step process under AEDPA).
II.
Under de novo review, Hardy was clearly prejudiced in the guilt phase by Demby’s deficient performance. Had Dem-by properly investigated and presented evidence that Boyd — the state’s key witness — actually committed the murders, there is a substantial probability the jury would have come to a different conclusion. Hardy is entitled to habeas relief because the California Supreme Court applied a standard contrary to clearly established law and because his attorney’s deficient performance was prejudicial at the guilt phase.
At trial, the State’s theory of the case centered on the existence of an “elaborate scheme or plan or design by Mr. Morgan!,] coupled with Mr. Reilly as the middleman!, which] culminated in the hiring of Mr. Hardy or the agreement by Mr. Hardy to go with Mr. Reilly to do the killing.” That is, Morgan hired Reilly to kill his family, Reilly then recruited Hardy, and the two entered Morgan’s home where Hardy killed Morgan’s wife and son. The State argued that Boyd and his friend Marcus had originally been enlisted to burglarize the Morgan residence but had ultimately withdrawn from the scheme.
According to the California Supreme Court, Boyd provided “two critical pieces of evidence” at trial: (1) Boyd testified that Reilly told Boyd that Hardy was the killer, and (2) Boyd saw Hardy and Reilly together just a few hours after the murder at Rice’s apartment.
Most of the other evidence presented against Hardy at trial came from Mitchell. Sportsman also testified that Hardy and Reilly spent a lot of time drinking and doing drugs together during the weeks surrounding the murders.
We note that the California Supreme Court actually did address the prejudicial effect of Demby’s performance but only in relation to Hardy’s actual innocence claim' — not as to his ineffective assistance claim. The California Supreme Court found the weight and breadth of the evidence regarding Boyd’s likely participation in the murder “would have presented a more difficult decision for the jury and may well have created in the minds of the jurors a reasonable doubt as to [Hardy’s] guilt.” The evidence regarding Boyd’s likely participation — which included evidence Boyd made incriminating statements before and after the murder, had a false alibi, carried a knife similar to the murder weapon, and had previously committed assaults — is precisely the same evidence that Hardy argues Demby should have investigated and presented at trial. The fact that the California Supreme Court acknowledged, in relation to Hardy’s innocence claim, how such evidence would have created a reasonable doubt as to Hardy’s guilt is equally applicable to Hardy’s ineffective assistance of counsel claim.
Nonetheless, the California Supreme Court held Hardy was not entitled to relief on the ineffective assistance of counsel claim because substantial evidence sup*821ported a theory Hardy was guilty of first degree murder on a conspiracy theory and on an aid-and-abet theory. Because Hardy was found guilty on a conspiracy charge, and because an aid-and-abet jury instruction was given along with the murder charge, the California Supreme Court concluded no prejudice occurred. Under de novo review, the California Supreme Court clearly erred.
First, as noted, the State’s entire theory of the case hinged on Hardy being the actual killer. Under no reasonable reading of the record could it be concluded the jury actually found Hardy guilty under an aid- or-abet theory. When the prosecutor addressed the aid-and-abet theory in his closing argument, he described only Morgan’s and Reilly’s involvement — not Hardy’s. Although the jury instruction regarding the murder charge included an aid-and-abet instruction and the jury found Hardy guilty of the murder charge, an aid-and-abet theory is wholly distinct6 from an actual killer theory and the jury could not simultaneously have found both true.7 Had Demby presented evidence that Boyd was the killer it would have completely undermined the prosecution’s theory of the case. As a result, there is a significant likelihood the jury would not have found that Hardy was guilty of murder beyond a reasonable doubt.
Further, the California Supreme Court found that “[ejvidence of Boyd’s incriminating' admissions, coupled with other evidence, could have convinced a reasonable jury to entertain some doubt as to the extent of [Hardy’s] participation in the murders.” The California Supreme Court also stated that had Boyd’s participation been revealed at trial it would have “throw[n] some doubt on the scope of [Hardy’s] role — said by the .prosecutor at trial to be a primary one — in the crimes.” These statements indicate the state court believed a jury would have seriously questioned what role, if any, Hardy had in the murders, including under an aid-and-abet theory, had Demby not performed defi-ciently as Hardy’s attorney.
Second, although Hardy was found guilty by the jury of conspiracy to commit murder for insurance proceeds, his conviction rested on being the actual killer. The California Supreme Court found the jury relied — at least in part — on a conspiracy theory in convicting Hardy and that sufficient evidence supported the theory. This theory fails for the same reasons the aid- and-abet theory fails. The prosecution argued Hardy was a member of the conspiracy because he agreed to, and actually *822did, commit the murders.8 Any remaining evidence linking Hardy to other minor acts involved in the conspiracy does little to rebut that the prosecution’s theory at trial would have been eviscerated had Demby not been deficient.
Additionally, there was at least some evidence adopted by the California Supreme Court that, even if Hardy was involved in the conspiracy at one point, he may have withdrawn from the conspiracy before the commission of the crimes. Hardy may have backed put before the crime was committed because, according to Boyd, Hardy was too “chicken shit to go along.” Whether this withdrawal would have occurred before any overt acts were taken — and therefore been effective — is unclear but it is additional evidence adopted by the state court that would cause a jury to view the conspiracy charge differently. Again, whether the jury could have or even likely would have convicted Hardy under this theory of conspiracy is irrelevant; what matters is the substantial likelihood the jury may not have convicted Hardy had Demby investigated and presented evidence about Boyd’s participation in the crime.
Third, even if the aid-or-abet and conspiracy theories of guilt could supplant what the jury found at trial — that Hardy was the actual killer — it is reasonably likely the jury would have had a reasonable doubt under those theories based on the evidence that should have been presented at trial. The California Supreme Court’s contrary conclusion was incorrect and is unsupported by the record. According to the state court, the substantial evidence that remained to convict Hardy under derivative theories consists almost entirely of Mitchell’s testimony and a few circumstantial statements made by Sportsman.
In support of its finding, the California Supreme Court cites Sportsman’s testimony linking Reilly to the murders. Sportsman testified that the day after the murders she saw Reilly and Hardy laughing and drinking. Sportsman also testified that Reilly encouraged her to speak to Hardy and Mitchell to coordinate alibis. According to Sportsman, Hardy and Reilly started drinking and doing drugs together ten days before the murders.
Beyond Sportsman’s testimony, the California Supreme Court relied solely on Mitchell to provide the “substantial evidence” that Hardy is guilty under a derivative theory. Mitchell testified that Hardy discussed his alibi frequently and that Hardy knew several details about the crimes. Most incriminatingly — according to the California Supreme Court — was that Hardy possessed $1,000 in $100 bills after the murders and that he instructed Mitchell to dispose of his shoes and an Ml carbine. The state court, however, recognized the weakness of Mitchell’s testimony — discounting most of it point-by-point. The court noted Mitchell “did not know, where the money came 'from, could not remember who informed her of the money’s origin, and could not remember the first time she saw the money.” The California Supreme Court added “[t]he persuasive power of [Mitchell’s] testimony was further undermined by the fact she was subject to impeachment due to her drug and alcohol use and that she admitted lying for [Hardy] at his preliminary hearing.”
The California Supreme Court found-that Sportsman’s and Mitchell’s testimony could support a finding that Hardy was *823guilty under a derivative theory assuming the jury found the testimony credible and persuasive. As previously explained, however, this is not the correct standard. The question is whether, if Demby had not performed deficiently, it is reasonably likely the jury would have reached a different outcome. Although the federal district court concluded that the jury specifically found Mitchell credible and relied on her testimony, this conclusion was purely speculative and not supported by the record. See Strickland, 466 U.S. at 695, 104 S.Ct. 2052 (“[Ejvidence about the actual process of decision, if not part of the record of the proceeding under review ... should not be considered in the prejudice determination.”). At least one juror stated that the jury specifically discussed Mitchell’s testimony and determined she was not credible. Further, Mitchell’s testimony would have been discounted by the jury had Demby presented evidence that Boyd’s testimony, which corroborated much of Mitchell’s testimony, was false.
The California Supreme Court described Boyd’s crucial role in Hardy’s trial calling it “extremely damaging to [Hardy’s] case” and stating that he provided evidence “on which the prosecution relied to convict [Hardy].” Removing Boyd’s extremely damaging testimony and its corroborating effect on Mitchell’s testimony would have significantly changed the case as presented to the jury. Despite some evidence remaining that Hardy may have somehow been involved in the murders under a derivative theory, had Demby not performed defi-ciently, there is a substantial likelihood the jury would have had a reasonable doubt concerning Hardy’s guilt.
Last, Strickland’s prejudice prong requires analyzing the evidence that would have been presented had counsel not performed deficiently. Bonin v. Calderon, 59 F.3d 815, 834 (9th Cir. 1995). Strickland held:
a court hearing an ineffectiveness claim must consider the totality of the evidence before the ... jury. Some of the factual findings will have been unaffected by the errors, and factual findings that were affected will have been affected in different ways. Some errors will have had a pervasive effect on the inferences to be drawn from the evidence, altering the entire evidentiary picture, and some will have had an isolated, trivial effect. Moreover, a verdict or conclusion only weakly supported by the record is more likely to have been affected by the errors than one with overwhelming record support. Taking the unaffected findings as a given, and taking due account of the effect of the errors on the remaining findings, a court making the prejudice inquiry must ask if the defendant has met the burden of showing that the decision reached would reasonably likely have been different absent the errors.
466 U.S. at 695-96, 104 S.Ct. 2052. Strickland does not permit the court to reimag-ine the entire trial. We must leave undisturbed the prosecution’s case. We only envision what Demby should have presented in Hardy’s defense and determine how that would have altered the trial. In doing so, we may not invent arguments the prosecution could have made if it had known its theory of the case would be disproved.
Here, this means the State would have called Boyd to the stand to testify that Hardy was the actual killer. Then Demby would have cross-examined Boyd, revealing compelling evidence that Boyd, not Hardy, was the actual killer. Though we might assume the State would attempt to rehabilitate Boyd as a witness, we cannot simply presume it would have been sue-*824cessful in doing so. Nor can we presume the State would have altered the entire theory of its case in response or been successful doing so. If the State had changed horses midstream, that alone would have created a substantial probability the jury would come to a different result. Demby’s failure to investigate Boyd’s role in this case altered the entire evidentiary picture. Viewing the trial in this manner, the California Supreme Court and the federal district court erred in finding there was no reasonable probability that the outcome would have been different but-for the deficient performance of counsel under any theory of conviction.9
This is not- a case where counsel’s deficient performance had no bearing on the outcome due to otherwise strong or overwhelming evidence of guilt. See, e.g., United States v. O’Neal, 937 F.2d 1369, 1376 (9th Cir. 1990) (no prejudice where there was strong evidence of guilt), abrogated on other grounds by United States v. Garcia-Cruz, 40 F.3d 986, 989 (9th Cir. 1994); United States v. Harden, 846 F.2d 1229, 1232 (9th Cir. 1988) (no prejudice where there was overwhelming evidence of guilt). Instead, the verdict was only weakly supported by the evidence. No witness except Boyd placed Hardy at the scene of the crime, no witness reported seeing Hardy leaving the apartment complex the night of the crime, and no blood, fingerprint, footprint, hair, or other forensic evidence linked Hardy to the crime. No murder weapon was found and no evidence was presented that linked Hardy to any knife similar to the one used by the killers. Indeed, no physical evidence whatsoever linked Hardy to the crime. Hardy was convicted of being the actual killer primarily on the strength of Boyd’s now discredited testimony. It cannot be reasonably argued that strong or overwhelming evidence of guilt under any theory exists without Boyd’s testimony. Thus, there is a substantial likelihood that the jury would not have convicted Hardy had Demby performed effectively.
III.
Even though the California Supreme Court recited the proper Strickland prejudice standard, it failed to apply the proper standard, and thus the decision is not protected from review for 28 U.S.C. § 2254(d) purposes. See Sears, 561 U.S. at 952, 130 S.Ct. 3259 (2010). Assuming, however, that the California Supreme Court did correctly conceptualize and apply the Strickland prejudice standard but simply camouflaged that understanding with a different — and incorrect — phrasing of the legal standard, we still conclude that its application was unreasonable.
Prior to the passage of AEDPA, federal courts reviewed state court convictions for habeas consideration using a standard akin to de novo review. See Brown v. Allen, 344 U.S. 443, 500-03, 73 S.Ct. 397, 97 L.Ed. 469 (1953). AEDPA revised the standard of review limiting a federal court’s review of state court decisions which are “contrary to, or involved an unreasonable application of, clearly established Federal law.” § 2254(d).
Three distinct terminologies have emerged to describe the “unreasonable application” portion of § 2254(d). The Supreme Court has described this standard as objective unreasonableness, double deference, and the fairminded jurist test. Although this may appear as simply a “mat*825ter of phrasing,” its discussion is necessary because “phrasing mirrors thought, and it is important that the phrasing not obscure the true issue” before the Court. Wright v. West, 505 U.S. 277, 304-05, 112 S.Ct. 2482, 120 L.Ed.2d 225 (1992) (O’Connor, J., concurring) (quoting Brown, 344 U.S. at 501, 73 S.Ct. 397). Regardless of which conception of “unreasonable application” is applied, the result is the same in this case— the California Supreme Court applied the Strickland prejudice test in an unreasonable fashion.
In Williams, the Supreme Court explained that “unreasonable” is a common term in the legal world and is to be measured objectively in the AEDPA context. Williams, 529 U.S. at 409-10, 120 S.Ct. 1495. Although the term “unreasonable” may be difficult to define in some scenarios, we know it means more than being merely erroneous or incorrect. Id. at 410-11,120 S.Ct. 1495.
Later, in explaining how § 2254(d) interacts with the Strickland test, the Supreme Court introduced the concept of “double deference.” Double deference refers to the layering of the reasonableness test from § 2254(d) on top of another reasonableness test, such as the deficiency prong of Strickland’s two part standard. Because only the prejudice prong is at issue here, double deference does not apply.10
More recently, the Supreme Court expressed the AEDPA standard slightly differently. In Harrington v. Richter, the Court phrased the application of Strickland under § 2254(d)(1) as “whether it is possible fairminded jurists could disagree” that theories or arguments the state court could have relied on were inconsistent with a prior Supreme Court decision. 562 U.S. 86, 101-02, 131 S.Ct. 770 (2011). This “fair-minded jurist” phrasing has oft been repeated since Richter in the AED-PA/Strickland context. See, e.g., Davis v. Ayala, — U.S.—, 135 S.Ct. 2187, 2199 (2015);. Pinholster, 563 U.S. at 188, 131 S.Ct. 1388; Andrews v. Davis, 798 F.3d 759, 774 (9th Cir. 2015).
In Williams, the Supreme Court explained that the “reasonable jurist” standard is an objective standard and is not the proper standard for determining what amounts to an “unreasonable application” under § 2254(d)(1). 529 U.S. at 409, 120 S.Ct. 1495 (“The placement of this additional overlay on the ‘unreasonable application’ clause was erroneous.”). Because Richter cited Williams approvingly, and because no Supreme Court decision has overruled Williams, it is clear that the “fairminded jurist” language in Richter is just an alternative way to describe the *826objective unreasonableness standard elucidated in Williams and not a new subjective standard.11
Applying an objective fairminded jurist standard does not mean that because any state judge found otherwise, the federal court is obliged to turn away a petitioner. Cf. Wright v. West, 505 U.S. 277, 304, 112 S.Ct. 2482 (1992) (O’Connor, J., concurring). Indeed, to do so would wholly negate § 2254 and function as a suspension of the writ of habeas corpus for state prisoners. It would mean that even were a state prisoner granted a writ by a state trial court, the government could appeal all throughout the state process and lose each step of the way but so long as one jurist on either the state appellate court or state supreme court dissented, any federal petition would be doomed to failure. Courts are to read laws in order to give them meaning, not to render them fully impotent. See Williams, 529 U.S. at 404, 120 S.Ct. 1495.
Under any reading of § 2254(d), we conclude that Hardy ⅛ entitled to relief. We must determine whether the California Supreme Court applied the prejudice prong of Strickland .in an unreasonable manner. It did.
The relevant inquiry under Strickland’s prejudice prong is “whether it is reasonably likely the result would have been different” had counsel not performed deficiently. Cannedy v. Adams, 706 F.3d 1148, 1162 (9th Cir. 2013) (quoting Harrington, 562 U.S. at 111-12, 131 S.Ct. 770). A court must “compare the evidence that actually was presented to the jury with that which could have been presented had counsel acted appropriately.” Thomas v. Chappell, 678 F.3d 1086, 1102 (9th Cir. 2012) (quoting Karis v. Calderon, 283 F.3d 1117, 1133 (9th Cir. 2002)). As described in detail in part II, if Demby had provided effective assistance of counsel, the State’s theory of the case that Hardy was the actual killer would have been eviscerated. If Demby had investigated Boyd and then presented evidence that he made incriminating statements before and after the murder, and that his alibi was false, the jury would have been torn between two conflicting theories on the identity of the second killer. This would have created a reasonable doubt as to Hardy’s guilt. To the extent the California Supreme Court concluded there was not a substantial likelihood of a different result, it did not simply arrive at an incorrect conclusion about prejudice but it applied the Strickland prejudice prong in an objectively unreasonable manner.
Hardy is entitled to relief based on the severity of Demb/s deficiency, the vital role Boyd’s testimony played in securing Hardy’s convictions, the lapses of the prosecution, and the utter dearth of other evidence inculpating Hardy.
Conclusion
Hardy was deprived of effective assistance of counsel at his trial and has demonstrated Strickland prejudice therefrom. Hardy’s attorney failed him, and the State of California failed Hardy by putting a man on the stand that it should have known committed the crime. We are not in a position to determine if, or to what extent, Hardy may have been involved in these heinous murders. But we can, and do, find that when the California Supreme Court failed to find ineffective assistance *827of counsel, its denial of Hardy’s claim was both contrary to and objectively unreasonable under Strickland. Accordingly, Hardy is entitled relief under AEDPA. We REVERSE the district court’s judgement and REMAND the. case to the district court with instructions to grant the petition for a writ of habeas corpus.
REVERSED and REMANDED.
. Morgan was also convicted of capital murder charges, but his case was severed from the other two co-defendants for the penalty phase because of his failing health. In re Hardy, 63 Cal.Rptr.3d 845, 163 P.3d at 863. Morgan died of bone cancer before the penalty phase of his separate trial. Id.
. Perhaps this case would not even be here had Justice Werdegar inserted “on the other hand, there is no reasonable probability the jury would have acquitted on the prosecution theories of conspiracy and aiding and abetting because ample evidence remains that petitioner was guilty of the murders on the alternative theories.” But can the second part of that paragraph be read any other way?
. Tellingly, the majority opinion does not mention Justice Werdegar’s use of the phrase “ample evidence” three times to describe the strong evidence that Hardy was guilty because of the derivative theories of liability.
. As noted above, the California Supreme Court opinion described this derivative liability evidence as “ample” when it expressly weighed the evidence by the reasonable-probability standard. See In re Hardy, 63 Cal.Rptr.3d 845, 163 P.3d at 890.
. Note the use of the precise term used in Strickland — "undermine confidence”- — to measure what constitutes prejudice under Strickland. See Strickland, 466 U.S. at 694, 104 S.Ct. 2052.
. During the event, the perpetrators took an M-l rifle from the Morgan home and cut a chain lock with bolt cutters to make it look as if a forcible entry and burglary had occurred. Actually, Reilly gained entry to the Morgan home with a key from Mr. Morgan.
. The opinion makes this point clear when it explains that the court would be required to vacate the murder convictions if the court were considering only the actual stabber theory. In re Hardy, 63 Cal.Rptr.3d 845, 163 P.3d at 888. But vacating the convictions is not necessary, according to the court, because the prosecutor also proceeded on the derivative theories of liability, and petitioner could not show prejudice as to the verdict because of the evidence which amply supported those theories of guilt. Id.
. See, e.g., John H. Blume, AEDPA: The "Hype” and the "Bite,” 9 Cornell L. Rev. 259 *814(2006); Lee Kovarsky, AEDPA’s Wrecks: Comity, Finality, and Federalism, 82 Tul. L. Rev. 443 (2007); Judith L. Ritter, The Voice of Reason — Why Recent Judicial Interpretations of the Antiterrorism and Effective Death Penalty Act’s Restrictions on Habeas Corpus are Wrong, 37 Seattle U. L. Rev. 55 (2013).
. The factual and procedural summary is taken from the district court's order. The district court relied on the Supreme Court of California. In re James Edward Hardy, 41 Cal.4th 977, 983-87, 63 Cal.Rptr.3d 845, 163 P.3d 853 (2007) (Hardy II).
. Specifically, the superior court judge found Boyd had admitted his guilt telling a friend "yes, man, I went in to do the lady in and Marcus and I were stumbling through the house, and I went through one room, I tripped upon the kid and grabbed a pillow and put it over his face and stabbed him.” The California Supreme Court explicitly adopted this finding.
. The State, with its more abundant resources, should also have discovered Boyd's role in the crime. Instead, the State concealed the existence of an immunity agreement with Boyd granted Boyd immunity and used him as its key witness against Hardy. The prosecutor's conduct in this case raises substantial concerns regarding the reliability of Hardy’s conviction even apart from the Demby's inadequate representation.
. Substantial evidence is also the standard California courts use in reviewing factual and credibility determinations made by a referee during a reference hearing. In re Cox, 30 Cal.4th 974, 998, 135 Cal.Rptr.2d 315, 70 P.3d 313 (2003). Here, the California Supreme Court properly applied the standard in that portion of its opinion concerning the reference hearing. Whether counsel's deficient performance prejudiced Hardy, however, is not subject to the substantial evidence standard and is independently reviewed.
. We do not suggest that a prosecutor can never present factually inconsistent theories. Rather, we emphasize that here the prosecutor presented just one theory to the jury: Hardy was the actual killer.
. In Taylor v. Beard, this court rejected a petitioner’s argument that because the jury found him guilty of being the actual shooter, it could not find him guilty of aiding and abetting. 811 F.3d 326, 327 (9th Cir. 2016) (en banc) (petition for cert, filed). Hardy's case is distinguishable from Taylor because Taylor was making a "freestanding innocence" claim and the additional evidence he presented tended to inculpate him further. Id. at 333-34. Hardy's Strickland claim, however, has a much more yielding standard. Additionally, Taylor was tried alone, a jury agreed on every element of the crime that Taylor essentially admitted to committing, and his jury did not need to agree unanimously on the theory presented. Id. at 332 (citing Schad v. Arizona, 501 U.S. 624, 631-32, 111 S.Ct. 2491, 115 L.Ed.2d 555 (1991)). In contrast, Hardy was tried with two other co-defendants who were alleged to be the aiders-and-abettors and Hardy was tried as the actual killer. Because of the critical differences in the standards that apply to an actual innocence claim versus the Strickland claim in this case and the dissimilar trial procedures used in these two cases, Taylor does not control this case.
. In his opening statement, the prosecutor stated that "there is no doubt in anyone's mind or ought to be that Mr. Hardy had the knife in his hand and plunged that knife into the bodies of those two people in excess of 65 times.”
. The Strickland test is clear, and it is not a sufficiency of the evidence standard nor is it a substantial evidence standard. The dissent incorrectly suggests otherwise and fails to address or analyze how the deficient performance by attorney Demby fundamentally prejudiced Hardy on all theories of criminal liability.
. Double deference applies when a federal court is reviewing a state court’s application of a general rule. Knowles v. Mirzayance, 556 U.S. 111, 129 S.Ct. 1411, 173 L.Ed.2d 251 (2009) (citing Yarborough v. Alvarado, 541 U.S. 652, 664, 124 S.Ct. 2140, 158 L.Ed.2d 938 (2004)). The more specific a legal rule is, the more narrow a range of reasonable application exists for that rule. Yarborough, 541 U.S. at 664, 124 S.Ct. 2140. Strickland’s deficiency prong presents a general rule because "[judicial scrutiny of counsel's performance must be highly deferential” and there is "a strong presumption that counsel’s conduct falls within the wide range of reasonable professional assistance.” 466 U.S. at 687-88, 104 S.Ct. 2052. Because ’’[t]here are countless ways to provide effective assistance in any given case,” courts must be hesitant in performing a post-hoc review of trial counsel's strategic choices. Id. at 689. Thus, the federal court asks whether it was reasonable for the state court to find whether trial counsel’s performance fell within the range of reasonable professional assistance. Because the prejudice prong of Strickland presents only a more specific legal rule, a case considering only that prong is not subject to double deference as described in Mirzayance.
. The dissent clings to a sdbjective interpretation of the Supreme Court’s “fairminded jurist” language, insisting § 2254(d) cannot be met because the California Supreme Court and the federal district court came to a different conclusion. Under this interpretation, there would be no reason for a federal appellate court to ever hear § 2254(d) appeals.
