UNITED STATES SUPREME COURT DECISIONS ON-LINE

The Government purportedly furnished petitioner, who has been convicted of income tax violations, all of his own conversations which had been overheard by unlawful electronic surveillance, and the District Court examined all the records in camera to ascertain if the Government had correctly identified petitioner's voice and had turned over all his conversations.

Held: Alderman v. United States, ante, p. 394 U. S. 165, requires an adversary proceeding only where in camera procedures are inadequate to safeguard a defendant's Fourth Amendment rights, but here it cannot be said that "the task is too complex, and the margin of error too great, to rely wholly on the in camera judgment of the trial court."

Certiorari granted; 398 F.2d 558, affirmed.
