United States v. Williams, 504 U.S. 36 (1992), was a U.S. Supreme Court case concerning the presentation of exculpatory evidence to a grand jury, ruling that the federal courts do not have the supervisory power to require prosecutors to present exculpatory evidence to the grand jury.

The question addressed by the court was whether a district court may properly dismiss an indictment when the prosecutor withheld “substantial exculpatory evidence” that could lead the grand jury to reject the indictment, but that does not necessarily rise to the level of prosecutorial misconduct, which would require the dismissal of an indictment.[2] The significance of the ruling lies not only in its definition of the duty of the prosecutor in regard to presenting exculpatory evidence before the grand jury, but also in its definition of the grand jury's accusatory role.[1]

The ruling protects prosecutors who withhold "substantial exculpatory evidence" in order to obtain an indictment, as the role of the grand jury is not to determine guilt, but rather to decide whether there is enough evidence of a crime; exculpatory evidence can be presented at trial. Justice Stevens' dissent focused on the argument that a prosecutor's failure to present substantially exculpatory evidence is a form of prosecutorial misconduct, but that nevertheless, the prosecutor need not "ferret out and present all evidence that could be used at trial to create a reasonable doubt as to defendant's guilt."[2]
