Summary

Byron White Gregg v. United States — Opinion of the Court

Presentence reports are documents which the rule does not make available to the defendant as a matter of right. There are no formal limitations on their contents, and they may rest on hearsay and contain information bearing no relation whatever to the crime with which the defendant is charged. To permit the ex parte introduction of this sort of material to the judge who will pronounce the defendant's guilt or innocence or who will preside over a jury trial would seriously contravene the rule's purpose of preventing possible prejudice from premature submission of the presentence report.

Byron White Gregg v. United States — Opinion of the Court

Even if this record revealed that the judge had read the presentence report after the jury retired and before the return of the verdict, the judge could not have infected the jury with anything he learned from the report since there was no necessity or occasion for communicating with the jury once it began its deliberations, and the jury delivered its verdict immediately upon emerging from seclusion.
