OPINION
Petitioner-Appellant, Paul Blanton, appeals the district court’s dismissal of his petition for a writ of habeas corpus. Blan-ton is currently imprisoned by the state of Michigan and is serving two non-parolable life sentences for two first degree murder convictions, twenty-five to fifty years for a second degree murder conviction, and two years for possessing a firearm during the commission of a felony. We affirm because the state court decision was not an unreasonable application of federal law.
I. BACKGROUND:
According to the prosecution’s theory of the three murders, Blanton lolled Sharon Matthews, Johnifer Harris, and Marty Allen because he wanted to steal their drugs and money. Blanton’s version of events is to the contrary. He says Matthews and Harris began arguing in the apartment and Allen shot them. Blanton maintains that he then wrestled the gun from Allen, but when Allen came at him with a knife, he shot Allen. He says that when he checked on Harris and Matthews, he saw that Harris had fallen through the second-floor window and was lying on the ground below. He thought he saw Harris move for his weapon, felt threatened, and shot Harris himself. He then moved Matthews’s body toward the apartment stairs so as to obtain medical help for her, but when he decided she was already dead, he moved her body back to where she was shot. He claims he never shot Matthews, but he did shoot Allen and Harris in self-defense.
Blanton was allowed to introduce some testimony from Dr. Ronald DeBoer, a clinical psychologist who was experienced in treating the effects of trauma and who had been treating Blanton for several months. The testimony permitted at trial related to post-traumatic stress syndrome and selective amnesia, evidence intended to help the jury understand why Blanton’s statements to the police differed somewhat from each other and why Blanton might not recall all details of the incident. Blanton proffered, but was not allowed to introduce, testimony from Dr. DeBoer which related to his state of mind at the time of the incident. In DeBoer’s opinion, at the time of the incident Blanton experienced “derealization,” a disruption in the perception of traumatic events as they are occurring. This testimony was offered to show how Blanton could have honestly and reasonably believed that he needed to act in self-defense against Harris and Allen.1 Because the trial court thought that the testimony related to a diminished capacity defense, for which the required pretrial notice had not been given, it excluded the testimony.
Blanton appealed his conviction to the Michigan Court of Appeals, asserting among other things that he had been denied his federal constitutional right to fairly present his defense. The Michigan Court of Appeals found that the testimony from DeBoer regarding “derealization” did not relate to a diminished capacity defense, but held that the error in excluding the testimony for that reason was harmless because the evidence was cumulative to Blanton’s own testimony.
*714Defendant testified in his own behalf and related his version which supported his self-defense theory regarding Harris and Allen and claimed that he did not shoot Matthews. Dr. DeBoer did testify at trial concerning post-traumatic stress syndrome and selective amnesia and that he believed that defendant suffered from both of these disorders. Dr. De-Boer explained that defendant consistently held to the belief that his life was in danger and that he perceived his life was in danger.
Because defendant testified to events supporting his defense of self-defense, any opinion testimony by Dr. DeBoer would have been cumulative. The jury still had to determine defendant’s credibility and whether he had an honest and reasonable belief that his life was in danger under all the circumstances as they appeared to defendant. Accordingly, contrary to defendant’s argument, the trial court did not deny him his right to present a defense by excluding Dr. DeBoer’s testimony concerning his mental state at the time of the offenses. Defendant fully testified to his version of events and presented his claim of self-defense.
People v. Blanton, No. 122342 at 5 (Mich.Ct.App. June 1, 1994) (citations omitted). The Michigan Supreme Court denied Blan-ton’s application for leave to appeal, with one justice dissenting.
The district court for the Eastern District of Michigan dismissed Blanton’s writ of habeas corpus upon recommendation of a magistrate judge.
Petitioner ... argues that Magistrate Carlson erred in finding that the proposed evidence regarding derealization was offered for the limited purpose of supporting credibility, and was therefore not critical factual testimony. The court agrees with petitioner that the outcome of credibility determinations may be critical to a jury’s verdict, but Dr. De-Boer was allowed to testify that petitioner suffered from post-traumatic stress syndrome and selective amnesia at the time of the shooting. This testimony went directly to petitioner’s credibility, and supported his testimony in full. Thus, petitioner was never denied the right to bring forward witnesses to support either his theory of the case, or his credibility.
Blanton v. Elo, No. 96-CV-71991-DT at 4 (E.D.Mich. Aug. 27, 1997).2 This court granted a certificate of appealability as to one issue: whether the trial court denied Blanton’s due process and Sixth Amendment rights when it ruled his evidence of derealization was inadmissible.
II. DISCUSSION:
Before a writ may issue under 28 U.S.C. § 2254, a federal court must find that the state court’s adjudication of the claim:
(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) resulted in a decision that was based on an unreasonable determination of the facts in light of the evidence presented in the State court proceeding.
28 U.S.C. § 2254(d).
This court has adopted the rule that:
the unreasonableness of a state court’s application of clearly established Supreme Court precedent will not be “debatable among reasonable jurists,” *715Drinkard, 97 F.3d at 769, if it is “so offensive to existing precedent, so devoid of record support, or so arbitrary, as to indicate that it is outside the universe of plausible, credible outcomes,” O’Brien, 145 F.3d at 25.
Nevers v. Killinger, 169 F.3d 352, 362 (6th Cir.1999) (quoting Drinkard v. Johnson, 97 F.3d 751, 769 (5th Cir.1996), cert. denied, 520 U.S. 1107, 117 S.Ct. 1114, 137 L.Ed.2d 315 (1997), overruled on other grounds by Lindh v. Murphy, 521 U.S. 320, 117 S.Ct. 2059, 138 L.Ed.2d 481 (1997), and O’Brien v. Dubois, 145 F.3d 16, 25 (1st Cir.1998)). This court reviews the district court’s denial of habeas corpus relief de novo. See Herbert v. Billy, 160 F.3d 1131, 1135 (6th Cir.1998).
The issue in the instant case involves whether the trial court was required to receive evidence from Dr. DeBoer on Blanton’s derealization at the time of the events in order to satisfy Blanton’s due process and Sixth Amendment rights. The issue is not one of the state court’s “determination of the facts in light of the evidence,” § 2254(d)(2), and there is no clear “rule” enunciated by the Supreme Court on the admissibility of such evidence, so we will decide whether the state court decision “involved an unreasonable application” of clearly established Supreme Court precedent under § 2254(d)(1). See Nevers, 169 F.3d at 358-61.
Blanton relies primarily on Crane v. Kentucky, 476 U.S. 683, 106 S.Ct. 2142, 90 L.Ed.2d 636 (1986), as the “clearly established federal law” which the Michigan court has misapplied.
Whether rooted directly in the Due Process Clause of the Fourteenth Amendment or in the Compulsory Process or Confrontation clauses of the Sixth Amendment, the Constitution guarantees criminal defendants “a meaningful opportunity to present a complete defense.” California v. Trombetta, 467 U.S. [479,] 485, 104 S.Ct. 2528, 81 L.Ed.2d 413 [ (1984) ]. We break no new ground in observing that an essential component of procedural fairness is an opportunity to be heard. That opportunity would be an empty one if the State were permitted to exclude competent, reliable evidence bearing on the credibility of a confession when such evidence is central to the defendant’s claim of innocence. In the absence of any valid state justification, exclusion of this kind of exculpatory evidence deprives a defendant of the basic right to have the prosecutor’s case encounter and “survive the crucible of meaningful adversarial testing.” United States v. Cronic, 466 U.S. 648, 656, 104 S.Ct. 2039, 80 L.Ed.2d 657 (1984).
Crane, 476 U.S. at 690-91, 106 S.Ct. 2142 (some citations omitted). In Montana v. Egelhoff, 518 U.S. 37, 116 S.Ct. 2013, 135 L.Ed.2d 361 (1996), the Court explained its holding in Crane.
Our holding that the exclusion of certain evidence in that case violated the defendant’s constitutional rights rested not on a theory that all “competent, reliable evidence” must be admitted, but rather on the ground that the Supreme Court of Kentucky’s sole rationale for the exclusion (that the evidence “did not relate to the credibility of the confession,”) was wrong. Crane does nothing to undermine the principle that the introduction of relevant evidence can be limited by the State for a “valid” reason....
Egelhoff, 518 U.S. at 53, 116 S.Ct. 2013 (citations omitted). Among the “familiar and unquestionably constitutional eviden-tiary rules” which authorize the exclusion of relevant evidence is Federal Rule of Evidence 403, which provides that relevant “evidence may be excluded if its probative value is substantially outweighed by ... considerations of undue delay, waste of time, or needless presentation of cumulative evidence.” See id. at 42, 116 S.Ct. 2013.
Because Blanton’s defense required him to show the jury that he honestly and reasonably believed his life to be in dan*716ger, and because those circumstances were to be judged from Blanton’s perspective at the time of the shooting, Dr. DeBoer’s proffered testimony regarding derealization was “competent, reliable evidence ... central to the defendant’s claim of innocence.” See Crane, 476 U.S. at 690, 106 S.Ct. 2142. The Michigan Court of Appeals found no abuse of discretion in the exclusion of that testimony, however, because there was a justification for the ruling made: the testimony was cumulative. The court saw DeBoer’s proffered testimony as cumulative of Blanton’s own because both testimonies involved Blanton’s mental state at the time of the events surrounding his defense of self-defense.
We cannot conclude that the Michigan court’s decision to affirm the exclusion of the evidence could not be “debatable among reasonable jurists” because it is “so offensive to existing precedent, so devoid of record support, or so arbitrary, as to indicate that it is outside the universe of plausible, credible outcomes.” Nevers, 169 F.3d at 362. Under Crane and Egelhoff it is not error to limit relevant evidence for a valid state reason, including cumulativeness, and there is no clearly established Supreme Court precedent on when testimony is improperly excluded as cumulative. We therefore cannot say that the state court decision “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,” 28 U.S.C. § 2254(d)(1).
AFFIRMED.
