Frank G. SPISAK, Jr., Petitioner-Appellant,
v.
Stuart HUDSON, Warden, Respondent-Appellee.
No. 03-4034.
United States Court of Appeals, Sixth Circuit.
January 11, 2008.
*853 Before: MARTIN, MOORE, and CLAY, Circuit Judges.

ORDER
On October 20, 2006, this Court issued an opinion partially granting habeas relief to Petitioner, Frank G. Spisak, and ordering a new mitigation phase trial. Spisak v. Mitchell, 465 F.3d 684 (6th Cir.2006). Respondent warden thereafter filed a petition for writ of certiorari with the United States Supreme Court. On October 9, 2007, the Supreme Court granted certiorari, vacated the judgment of this Court, and remanded the case to this Court for further consideration in light of Carey v. Musladin, ___ U.S. ____, 127 S.Ct. 649, 166 L.Ed.2d 482 (2006), and Schriro v. Landrigan, ___ U.S. ____, 127 S.Ct. 1933, 167 L.Ed.2d 836 (2007). After careful review and consideration of Musladin and Landrigan, we find that neither of the cases require reversal of our prior disposition of this case. Accordingly, We reinstate our opinion of October 20, 2006, partially granting habeas relief and ordering a new mitigation phase trial.
In. Spisak v. Mitchell 465 F.3d 684 (6th Cir.2006), this Court found that Petitioner presented a valid claim of ineffective assistance of counsel entitling him to habeas relief. In particular, this Court found that Petitioner was prejudiced by his counsel's deficient performance at the sentencing phase of Petitioner's trial inasmuch as counsel's closing argument focused almost entirely on the heinous nature of Petitioner's crimes and his deficient nature as a person. Defense counsel in no way attempted to rehabilitate Petitioner in the eyes of the jurors who would eventually have to decide whether to recommend the death penalty. There is no evidence in the record suggesting that Petitioner in any way contributed or consented to counsel's outrageous remarks during closing arguments. Relying on Supreme Court precedent applying the standard for ineffective assistance of counsel, this Court reasoned that defense counsel's conduct was so deficient, prejudicial and indeed, egregious, that it overcame the high bar for habeas relief established by the Antiterrorism and Effective Death Penalty Act of 1996 ("AEDPA");[1] consequently, we remanded for a new mitigation phase trial.
Upon review of Musladin and Landrigan, we find that they are readily distinguishable, and therefore Petitioner remains entitled to habeas relief as a result of the ineffective assistance of counsel at the mitigation phase of his trial.
In Carey v. Musladin, a habeas petitioner sought a writ of habeas corpus contending that he had been denied a fair trial after trial spectators wore buttons to the trial which displayed a picture of the murder victim. 127 S.Ct. at 651. A state court held that the display of buttons picturing the victim did not deny the defendant his right to a fair trial. Id. The Ninth Circuit Court of Appeals reversed, finding that the state, court's decision was *854 "contrary to or an unreasonable application of, clearly established federal law as determined by the Supreme Court." The Ninth Circuit applied Estelle v. Williams, 425 U.S. 501, 96 S.Ct. 1691, 48 L.Ed.2d 126 (1976) (defendant forced to wear prison garb by the state denied right to a fair trial) and Holbrook v. Flynn, 475 U.S. 560, 106 S.Ct. 1340, 89 L.Ed.2d 525 (1986) (finding that the seating of "four uniformed state troopers" in spectators row immediately behind defendant constituted the denial of the right to a fair trial) to find that the spectators' conduct was so inherently prejudicial that it denied the defendant his right to a fair trial. Id. at 652. The Supreme Court reversed, noting that whether spectator conduct, as opposed to state sponsored courtroom practices, could violate a defendant's constitutional right to a fair trial was "an open question in our jurisprudence." Id. at 654. Indeed, at the time Musladin was decided, courts across the country held divergent views on the application of Williams and Flynn to spectator conduct. Id. (collecting cases). Consequently, the failure of the state court to extend Williams and Flynn to spectator conduct was not an "unreasonable application" of "clearly established" federal law. Id.
In our view, Musladin is readily distinguishable from Spisak. First, Musladin is factually inapposite. Musladin involved a habeas petition alleging an infringement on the right to a fair trial based upon spectator conduct whereas Spisak alleged constitutionally ineffective assistance of counsel as a result of counsel's arguments to the jury.
Second, unlike Musladin, our holding in Spisak did not address an undeveloped area of the law; rather, this Court's holding partially granting habeas relief relied on well-settled Supreme Court precedent regarding ineffective assistance of counsel, i.e., Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984) and Wiggins v. Smith, 539 U.S. 510, 123 S.Ct. 2527, 156 L.Ed.2d 471 (2003). The Supreme Court has been quite clear in applying precedent regarding ineffective assistance of counsel to the mitigation phase of trials. Federal law regarding ineffective assistance of counsel of the kind addressed in Spisak was therefore "clearly established."
Third, the fact that the Supreme Court has not squarely addressed a situation involving a counsel's deficient performance during closing arguments of the mitigation phase of a trial does not preclude this Court's finding that the state court unreasonably applied federal law as announced in Strickland. Indeed, as the Supreme Court recently noted in Panetti v. Quarterman, 551 U.S. ____, 127 S.Ct. 2842, 168 L.Ed.2d 662 (2007), "AEDPA does not `require state and federal courts to wait for some nearly identical factual pattern before a legal rule must be applied."' Id. at 2858 (quoting Musladin, 127 S.Ct. at 656 (Kennedy, J., concurring)). Accordingly, we may find the application of a principle of federal law unreasonable despite the "involve[ment of] a set of facts `different from those of the case in which the principle was announced.'" Id. (quoting Lockyer v. Andrade, 538 U.S. 63, 76, 123 S.Ct. 1166, 155 L.Ed.2d 144 (2003)); see also Smith v. Patrick, 508 F.3d 1256, 1259 (9th Cir.2007) ("Habeas relief is appropriate under the `unreasonable application' prong of section 2254(d)(1) when a state court violates the principle of clearly established federal law that has been determined by the Supreme Court. . . .") (emphasis original). Thus, this Court's holding in Spisak was consistent with the mandate of AEDPA that federal courts are not to disturb state court determinations unless the decision was "contrary to, or involved an unreasonable application of, clearly established Federal law as determined *855 by the Supreme Court of the United States." 28 U.S.C. § 2254(d)(1).
In Schriro v. Landrigan, the Supreme Court considered whether a habeas petitioner presented a colorable claim of ineffective assistance of counsel. 127 S.Ct. at 1937. In Landrigan, the petitioner alleged that he received ineffective assistance of counsel after his lawyer failed to offer mitigating evidence at sentencing and did not adequately investigate mitigating evidence. Id. at 1938. The Supreme Court, however, disagreed. Applying the Strickland standard, the Court found that defense counsel's performance was neither deficient nor did it prejudice the petitioner. Id. at 1944. The Court found that the petitioner could not demonstrate that his counsel was deficient in failing to offer mitigating evidence at sentencing because the petitioner: (1) prohibited mitigation witnesses from testifying regarding his difficult upbringing and family history of substance abuse; (2) told the trial judge that no mitigating evidence existed; and (3) interfered with the presentation of mitigation evidence. Id. at 1941-42. The petitioner even told the sentencing court "I think if you want to give me the death penalty, just bring it right on. I'm ready for it." Id. at 1943. Additionally, the Court found that the petitioner could not demonstrate prejudice as a result of defense counsel's failure to further investigate mitigating evidence. The Court noted that the mitigating evidence that would have been discovered was "weak" in comparison to the overwhelming aggravating evidence and duplicative of the evidence that the petitioner had instructed counsel not to introduce regarding his family history. Id. at 1944. Consequently, the petitioner was denied habeas relief as he could not make out a colorable claim of ineffective assistance of counsel.
In Spisak, however, the story is quite different. Unlike Landrigan, Defence counsel in Spisak was clearly deficient inasmuch as he described Petitioner as "undeserving of sympathy" and "demented." The evidence on the record demonstrates that counsel "was not functioning as the `counsel' guaranteed the defendant by the Sixth Amendment." Strickland, 466 U.S. at 687, 104 S.Ct. 2052. For example, during his closing argument at the mitigation phase of trial, counsel engaged in a "graphic and overly descriptive recounting of Defendant's, crimes. . . ." Spisak, 465 F.3d at 705. Unlike Landrigan, there is no evidence that Petitioner consented to this line of argumentation or prevented counsel from presenting a more persuasive case for leniency. Rather, it appears that counsel independently pursued, this course of conduct and left Petitioner to suffer the consequences of the prejudicial remarks. Indeed, the prejudice that occurred in this case is quite stark. Certainly, it is, one thing not to introduce mitigating evidence as in Landrigan, but it is quite another to lend credence to the aggravating evidence presented by the prosecution by, essentially describing one's own client as a monster. We remain convinced that had Spisak's counsel not demonized Spisak in his arguments to the jury, there is a reasonable probability that at least one juror would have had a different opinion of the proper outcome in this case.
For the reasons stated above, we reinstate our previous opinion in this matter, Spisak v. Mitchell, 465 F.3d 684 (6th Cir. 2006), and remand Petitioner's case to the district court for further proceedings consistent with our previous disposition.
IT IS SO ORDERED.
KAREN NELSON MOORE, Circuit Judge, concurring in part and dissenting in part.
I concur in the majority order reinstating the opinion of October 20, 2006, but *856 again dissent as to Issue 1 and reinstate my prior opinion as well. In Panetti v. Quarterman, 551 U.S. ____, 127 S.Ct. 2842, 168 L.Ed.2d 662 (2007), the Supreme Court clarified its holdings in Schriro v. Landrigan, 550 U.S. ____, 127 S.Ct. 1933, 167 L.Ed.2d 836 (2007), and Carey v. Musladin, 549 U.S. ____, 127 S.Ct. 649, 166 L.Ed.2d 482 (2006). Panetti solidifies my position in this case by clearly stating that "AEDPA does not `require state and federal courts to wait for some nearly identical factual pattern before a legal rule must be applied.'" Panetti, 127 S.Ct. at 2858 (quoting Musladin, 127 S.Ct. at 656 (Kennedy, J., concurring)). "Nor does AEDPA prohibit a federal court from finding an application of a principle unreasonable when it involves a set of facts `different from those of the case in which the principle was announced.'" Id. (quoting Lockyer v. Andrade, 538 U.S. 63, 76, 123 S.Ct. 1166, 155 L.Ed.2d 144 (2003)). A recent Ninth Circuit decision (generated after the Supreme Court vacated and remanded a case for it to address the effect (if any) of Musladin) noted, after citing Panetti, that "[h]abeas relief is appropriate under the `unreasonable application' prong of section 2254(d)(1) when a state court violates the principle of clearly-established federal law that has been determined by the Supreme Court." Smith v. Patrick; 508 F.3d 1256, 1259 (9th Cir.2007) (citing Williams v. Taylor, 529 U.S. 362, 120 S.Ct. 1495, 146 L.Ed.2d 389 (2000)). The constitutional principles derived from Chambers v. Mississippi, 410 U.S. 284, 302, 93 S.Ct. 1038, 35 L.Ed.2d 297 (1973), and Crane v. Kentucky, 476 U.S. 683, 690, 106 S.Ct. 2142, 90 L.Ed.2d 636 (1986), not their specific facts, remain key in this case. Because Spisak's entire defense centered on his alleged insanity, the Supreme Court of Ohio's decision not to allow evidence critical to this defense (and its refusal to submit the insanity defense to the jury) violated his right, clearly established in Chambers and Crane, to present evidence essential to his defense. Therefore, once again, I respectfully dissent from the majority's treatment of Spisak's insanity defense, and I reinstate my dissent.
NOTES
[1]  Under AEDPA, an application for a writ of habeas corpus will not be granted unless the prior state proceedings (1) "resulted in a decision that was contrary to, or involved an unreasonable application of, clearly established Federal law as determined by the Supreme Court of the United States;" or (2) involved "an unreasonable determination of the facts in light of the evidence presented in the State court proceeding." 28 U.S.C. § 2254(d)(1)-(2).
