High Quality Content by WIKIPEDIA articles! United States v. Dominguez Benitez, 542 U.S. 74 (2004), was a United States Supreme Court case in which the Court ruled that, in a criminal proceeding in federal court, a defendant who does not alert the district court to a possible violation of Rule 11 of the Federal Rules of Criminal Procedure must show on appeal that the violation affirmatively affected his rights in order to obtain reversal of his conviction by guilty plea. Rule 11, which pertains to criminal prosecutions in United States federal courts only, governs the offering of plea bargains to criminal defendants and the procedures district courts must employ to ensure that the defendant knows of and properly waives his trial-related constitutional rights.
