prosecution's failure to produce the polygraph examinations. The District Court denied the writ, concluding that respondent "fails . . . to show that evidence was withheld. The information withheld only possibly could have led to some admissible evidence. He fails to show that disclosure of the results of the polygraph to defense counsel would have had a reasonable likelihood of affecting the verdict." App. to Pet. for Cert. B5 (emphasis in original).
On appeal, the Ninth Circuit reversed. 34 F. 3d 870 (1994). The Court of Appeals noted that under Washington law polygraphic examinations are inadmissible in evidence, even for impeachment purposes. See id., at 875 (citing State v. Ellison, 36 Wash. App. 564, 676 P. 2d 531 (1984)). The court nevertheless reversed the District Court's denial of the writ, concluding that although the results would have been inadmissible at trial, the information was material under Brady. The court reasoned that "[h]ad [respondent's] counsel known of the polygraph results, he would have had a stronger reason to pursue an investigation of Rodney's story"; that he "likely would have taken Rodney's deposition" and that in that deposition "might well have succeeded in obtaining an admission that he was lying about his participation in the crime" and "would likely have uncovered a variety of conflicting statements which could have been used quite effectively in cross-examination at trial." 34 F. 3d, at 875-876.

If the prosecution's initial denial that polygraph examinations of the two witnesses existed were an intentional mis-statement, we would not hesitate to condemn that misrepresentation in the strongest terms. But as we reiterated just last Term, evidence is "material" under Brady, and the failure to disclose it justifies setting aside a conviction, only where there exists a "reasonable probability" that had the evidence been disclosed the result at trial would have been different.
