United States v. Jorn

Background

The case involved the federal government and a man accused of willfully helping to prepare fraudulent income tax returns. He was originally charged with 25 counts. At the 1968 trial a jury was impaneled, the government dismissed 14 counts, and the remaining 11 tax returns were admitted by stipulation. Five taxpayers were to be government witnesses. After the first witness was called, defense counsel asked that the witnesses be warned about their right not to incriminate themselves. The judge warned the witness, then refused to let him testify until he had consulted a lawyer, expressed disbelief about earlier warnings, discharged the jury, and stopped the trial so the witnesses could consult attorneys. The defendant sought dismissal on double jeopardy grounds and the trial judge dismissed the information; the government appealed.

Reasoning

The Court addressed whether reprosecution was barred when a trial judge on his own motion declared a mistrial. Reviewing prior cases and the "manifest necessity" standard, the Court concluded the judge abused his discretion here. The judge acted abruptly, cut off the prosecutor, failed to consider a continuance or objections, and ignored assurances that witnesses had been warned. Because the mistrial was not justified under the governing standard, the Court held that retrying the defendant would violate the Fifth Amendment's double jeopardy protection, so the dismissal must stand.

Real world impact

The decision prevents retrial when a judge unjustifiably aborts a trial and strengthens protections for defendants against repeat prosecutions after improper mistrials. It puts pressure on trial judges to consider continuances and on prosecutors to ensure witnesses are warned before trial. The ruling will affect how judges handle sudden trial interruptions in criminal cases.

Dissents or concurrances

A dissent argued that an abuse-of-discretion finding alone should not always bar retrial when the mistrial benefitted the defendant and did not show prosecutorial harassment; the Chief Justice concurred reluctantly, agreeing the record showed an improper mistrial; two Justices questioned appellate jurisdiction but joined the judgment.
