In brief
Overview
According to United States, the United States v. Cotton et al. is a federal drug prosecution in which the respondents were charged under a superseding indictment that did not specify the exact quantity of cocaine involved.
Background and question before the Court
According to Justice Scalia, the Court heard arguments concerning whether errors at the grand‑jury stage that are cured at trial should affect the defendants’ substantial rights.
Justice Kennedy asked whether a sentencing error could simply be sent back to the trial judge for correction.
According to Justice O'Connor, justice O’Connor questioned whether the case required overruling *Ex parte Bain* and whether the issue was jurisdictional because the indictment lacked a specific quantity.
Justice Ginsburg asked whether the error in question qualified as a jurisdictional defect.
Justice Breyer warned that recognizing grand‑jury errors could open the floodgates to challenges of grand‑jury proceedings.
According to Chief Justice, chief Justice questioned whether second‑guessing the grand jury is any worse than second‑guessing a petty jury.
