The appellant, Cornelious Perry, was convicted of aggravated assault in California Superior Court. Contending that the exclusion of two defense witnesses violated due process, Perry petitioned for a writ of habeas corpus in federal district court. The district court denied the petition, and Perry appeals. We affirm.
FACTS
A young woman, walking through Golden Gate Park at about 4:30 p.m., stopped to ask directions of a man who was jogging with a dog. The man gave her directions and then, against her wishes, began to walk with her. The man offered her some money, which she refused. He then grabbed her around the neck and began trying to pull her off the path. When the woman screamed and clung to tree branches, he banged her head against them. The screams attracted bystanders. The assailant fled. One citizen chased the assailant and, as the chase neared a police station, ran in to get help. Emerging, the citizen saw a man standing on the sidewalk with his dog. The citizen told the police that this *1449 was the man he had been chasing, and the police arrested him. The man was Perry.
The victim identified Perry as her assailant at the police station shortly after the attack and again at trial. She based her identification on Perry’s general appearance and on a distinctive scar on his forehead. Other witnesses also identified Perry as the man they had seen in the park shortly before the attack and again when he was running from the area after the screams were heard.
In his own defense, Perry testified that he had never entered the park that day. Perry sought to support his story by introducing evidence that another man, Wolfe, might have committed the assault and been confused with Perry. The evidence consisted of testimony of two witnesses who had been robbed and raped by Wolfe in the same area of the park. One attack had occurred exactly three years earlier, and the second only an hour before the assault with which Perry was charged. Both Perry and Wolfe are black, of similar height and weight, and had distinctive “sectionally braided” hair on the day of the assault. On that afternoon, Wolfe was wearing a brown leather jacket and blue jeans; Perry wore a light brown jacket and blue warm-up pants. Wolfe has been convicted of both previous attacks.
California Evidence Code section 352 governs the admission of such collateral evidence:
The court in its discretion may exclude evidence if its probative value is substantially outweighed by the probability that its admission will (a) necessitate undue consumption of time or (b) create substantial danger of undue prejudice, of confusing the issues, or of misleading the jury. 1
California cases supply a gloss on section 352 when evidence is advanced that a third party may have committed the crime. Under the so-called
“Mendez-Arline
” rule, evidence of third party culpability is inadmissible “if it simply affords a possible ground of suspicion against such person; rather, it must be coupled with substantial evidence tending to directly connect that person with the actual commission of the offense.”
People v. Green,
Three times during the course of the trial the judge considered whether to admit evidence of Wolfe’s acts. Perry argued that this evidence showed that a similar looking person was in the same area of the park at about the same time, and was committing assaults in a similar fashion. After viewing photographs of Perry and Wolfe, however, the judge decided that misidentification was unlikely: “Except for the race of the man, there is nothing similar.” The judge therefore excluded the testimony under Rule 352.
Perry was convicted and sentenced to three years’ imprisonment. The California Court of Appeals affirmed the conviction over a vigorous dissent.
People v. Perry,
I.
Perry argues that the application of California evidence law violated his sixth and *1450 fourteenth amendment rights. Generally, of course, the states are free to fashion rules of evidence and procedure for their own courts. The United States Constitution, however, imposes some limits on the state’s power to exclude evidence in criminal cases.
The sixth amendment guarantees the accused “compulsory process for obtaining witnesses in his favor.” This right is a part of the due process that the fourteenth amendment requires of the state.
Washington v. Texas,
The defendant’s right to present evidence, however, is not absolute. “In the exercise of this right, the accused, as is required of the State, must comply with established rules of procedure and evidence designed to assure both fairness and reliability in the ascertainment of guilt and innocence.”
Chambers,
Supreme Court decisions provide limited guidance in resolving this clash between state rules and the defendant’s right to introduce evidence. On several occasions, the Court has held that state evidentiary rulings were unconstitutional. Yet, in each case, the court has limited its rulings to the specific facts before it.
Green v. Georgia,
The Supreme Court seems to have applied a balancing test to resolve such conflicts, weighing the interest of the defendant against the state interest in the evidentiary rule.
See Chambers,
The selection of a balancing approach, however, does not end our inquiry; we must still determine what weight the various interests will carry when placed on the scales. The right to present a defense is fundamental.
Chambers,
Fundamental standards of relevancy, subject to the discretion of the court to exclude cumulative evidence and to insure orderly presentation of a case, require the admission of testimony which tends to prove that a person other than the defendant committed the crime that is charged. See Chambers v. Mississippi,410 U.S. 284 , 302,93 S.Ct. 1038 , 1049,35 L.Ed.2d 297 (1973); Pettijohn v. Hall,599 F.2d 476 , 482 (1st Cir.) cert. denied,444 U.S. 946 ,100 S.Ct. 308 ,62 L.Ed.2d 315 (1979); United States v. Robinson,544 F.2d 110 , 113 (2d Cir.1976), cert. denied,434 U.S. 1050 ,98 S.Ct. 901 ,54 L.Ed.2d 803 (1977); Holt v. United States,342 F.2d 163 , 165-66 (5th Cir.1965). The exclusion of this testimony was prejudicial, and we reverse the conviction on count II.
Id. at 953.
Although citing constitutional cases,
Armstrong
reviewed an application of the Federal Rules of Evidence by the federal district court. We reversed because the district court had made an error in applying those rules. Mention was made of neither the sixth amendment nor due process. Nothing in
Armstrong
supports a belief that the Federal Rules of Evidence are constitutionally required, or that the Constitution requires admission of all relevant evidence. For the same reason the petitioner’s reliance upon
United States v. Robinson,
The defendant’s general right to present evidence is undeniably strong; yet the state’s legitimate interest in reliable and efficient trials is also compelling.
See Younger v. Harris,
Two Supreme Court cases demonstrate the unusually compelling circumstances required to outweigh the strong state interest in administration of its trials. In
Chambers v. Mississippi,
In
Washington v. Texas,
The Texas rule was apparently grounded on the belief that accomplices would be inclined to lie in order to get each other acquitted.
Id.
at 21,
In each of these cases, the evidence was highly exculpatory: third party confessions, if believed, would
necessarily
exonerate the defendant of the primary offense. In each case, also, the evidence was crucial to the defense; no other avenues were available to prove the defendant’s story. From these precedents, the district court in this case concluded that only the exclusion of evidence that is both exculpatory and crucial can violate due process.
Thus, both the defendant and the state have important and legitimate interests; both must be evaluated and weighed. 3 The exclusion of significant defense evidence implicates constitutional values. When due process issues are presented, the court must balance the importance of the evidence against the state interest in exclusion. In evaluating the significance of the evidence, the court should consider all of the circumstances: its probative value on *1453 the central issue, its reliability, whether it is capable of evaluation by the finder of fact, whether it is the sole evidence on the issue or merely cumulative, and whether it constitutes a major part of the attempted defense. The weight of the state’s interest likewise depends upon many factors. The Court must determine the purpose of the rule, its importance, how well the rule implements this purpose, and how well the purpose applies in the case at hand. The court must give due weight to the substantial state interest in preserving orderly trials, in judicial efficiency, in excluding unreliable or prejudicial evidence.
Due process draws a boundary beyond which state rules cannot stray; it does not displace the law of evidence with a constitutional balancing test. State rules are designed not to frustrate justice, but to promote it. Our common rules of evidence — testimonial privileges, the hearsay rule — have been justified by long experience.
Chambers,
II.
We consider now the application of the balancing test to the facts at hand. We are faced with a California ruling which excluded evidence of possible relevance.
See
1 J. Wigmore, Evidence § 139 (3d ed. 1940). The
Mendez-Arline
rule is not a common rule of evidentiary law, but seems peculiar to California. It has been criticized by California judges.
See People v. Perry,
The state’s interest in application of its rule in this case, while not compelling, was significant. The asserted rationale of the
Mendez-Arline
rule is “to place reasonable limits on the trial of collateral issues ... and to avoid undue prejudice to the People from unsupported jury speculation as to the guilt of other suspects.”
People v. Green,
The second state interest — the avoidance of unsupported jury speculation as to the guilt of other suspects — is related to the first one. The danger of unsupported jury speculation follows from the injection of collateral issues into the trial. The jury is the proper body to weigh conflicting inferences of fact, but there clearly is some point at which evidence may be so lacking in probity and so productive of con *1454 fusion that it may constitutionally be excluded. The state had a legitimate interest here in avoiding confusion of the jury. The strength of that interest, however, depends upon how extraneous the excluded evidence actually was. To make that determination, we must look to the defendant’s side of the balance.
The connection of the proffered evidence to the defendant’s case is tenuous. The testimony concerning Wolfe would show that another black man, of roughly Perry’s height and weight, wearing braided hair and somewhat similar clothing was near the scene an hour before and had a history of sexual assaults. The identification of Perry, however, was strong. The victim positively identified Perry only minutes after the attack. Wolfe had no dog. Wolfe lacked the prominent forehead scar that Perry has, and (the trial judge found) does not resemble Perry in facial features. Wolfe was clean shaven, while Perry wore a moustache and chin whiskers. Finally, although both wore blue pants, Wolfe’s jeans were not likely to be mistaken for the warm-up pants worn by Perry. The evidence thus possessed only slight probative value on the reliability of the identification.
Perry’s case is therefore analogous to
United States v. Brannon,
Perry argues that his evidence still raised a significant question of identity similar to that faced in
Pettijohn v. Hall,
The First Circuit found that, although possibly irrelevant as impeachment of the victim’s identification, Griffin’s testimony was “critically relevant” to support Pettijohn’s contention of misidentification. Id. at 480. The court found the alleged unreliability of the recanted identification an insufficient reason to justify exclusion: “If the Supreme Court cases of Washington v. Texas, supra, and Chambers v. Mississippi, supra, mean anything, it is that a judge cannot keep important yet possibly unreliable evidence from the jury.” Id. at 481. The court held that the exclusion violated Pettijohn’s constitutional rights.
The differences between Pettijohn’s case and Perry’s are significant. In Pettijohn one of the two witnesses to the crime identified a person other than Pettijohn as the *1455 robber; here, no one has ever identified Wolfe as the assailant. Griffin’s testimony would show that a mistaken identification had occurred; the Wolfe testimony would show only that one could possibly have occurred. Perry’s case is thus considerably weaker than Pettijohn’s.
Perry’s case is also distinguishable from
United States v. Crenshaw,
Perry argues that evaluating the evidence is a task for the jury. Of course, the trial judge was not resolving an issue of credibility of witnesses. The issue was not credibility, but the probity of the evidence compared to its tendency to divert the trial and confuse the jury. Nevertheless, Perry’s argument is not without force. At some point, evidence of collateral crimes by others may become so closely connected with the issue at trial, because of the similarity of personal identifying characteristics, or of modus operandi, or because of proximity of time and place, that the evidence could not be kept from the jury. The trial judge would then be obligated to let the jury evaluate the evidence even if the judge would not have found that evidence convincing had he or she been sitting as the trier of fact. We conclude, however, that the evidence offered by Perry was not so closely connected to the issue of his guilt or innocence that its exclusion, based on its lack of probity and its tendency to confuse the jury, violated due process or the right of compulsory process.
In summary, Perry’s proffered evidence falls far short of the critical and reliable evidence considered in Chambers and Webb. It is also less weighty and central than the disputed evidence in Pettijohn and Crenshaw. While Perry’s evidence is not actually irrelevant, it is sufficiently collateral and lacking in probity on the issue of identity that its exclusion did not violate the sixth and fourteenth amendments. California may constitutionally require more cogent evidence than this before opening up collateral issues at trial.
The judgment of the district court is accordingly AFFIRMED.
Notes
. California Evidence Code § 352 is very similar to Federal Rule of Evidence 403. Rule 403 provides:
Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by consideration of undue delay, waste of time, or needless presentation of cumulative evidence.
