Portrait of Abe Fortas Abe Fortas Giles v. Maryland — Concurrence

A criminal trial is not a game in which the State's function is to outwit and entrap its quarry. The State's pursuit is justice, not a victim. If it has in its exclusive possession specific, concrete evidence which is not merely cumulative or embellishing and which may exonerate the defendant or be of material importance to the defense-regardless of whether it relates to testimony which the State has caused to be given at the trial-the State is obliged to bring it to the attention of the court and the defense.

But I do not accept the notion that only where the effect of withholding evidence is to allow perjured testimony to stand uncorrected is there a duty to disclose. In my view, a supportable conviction requires something more than that the State did not lie. It implies that the prosecution has been fair and honest and that the State had disclosed all information known to it which may have a crucial or important effect on the outcome.

Finally, the plurality overlooks that there is uncontested testimony that Joyce was plainly and pertinently confused at the preliminary hearing. The plurality's speculation that she may or may not have been confused at one stage of this lengthy proceeding can scarcely vitiate the firm finding of the Maryland courts that she was confused at another and more crucial stage, and that this confusion explained any discrepancies in her accounts of these events. In sum, I find the plurality's oblique efforts to cast doubt on the finding of the state courts entirely unpersuasive.
