Brock v. North Carolina

Background

Three striking mill employees were arrested after shots were fired into a watchman’s house. Two of them confessed and were tried and convicted first. The third man was then placed on trial; the State called the two convicted co-defendants as witnesses, but they refused to answer on the ground that their answers might incriminate them. The trial judge sustained that claim and, at the State’s request, withdrew a juror and declared a mistrial so the State could try the case later after the co-defendants’ appeals were resolved. After the co-defendants’ convictions were affirmed, the defendant was retried, convicted, and sentenced to two years.

Reasoning

The Court addressed whether making a defendant stand trial again after a judge-ordered mistrial denies the Fourteenth Amendment’s protection of due process. The majority relied on earlier cases that allow a trial judge discretion to declare a mistrial when necessary to serve the ends of justice. The Court concluded that the North Carolina practice of allowing a mistrial for that reason did not deny the fundamental essentials of a fair trial and therefore did not violate due process in this record. The judgment of the state court was affirmed.

Real world impact

The decision means state trial judges have room to declare mistrials and order new trials when they judge it necessary to secure justice, for example when key testimony is unavailable at the moment. Criminal defendants in state courts can be retried after such a mistrial without automatically winning a constitutional ban on retrial. The case turns on judge-by-judge, fact-by-fact assessments rather than a fixed rule.

Dissents or concurrances

A concurrence warned against successive retrials used to let prosecutors try again for convenience, while dissenting opinions argued that allowing a mistrial for the State’s benefit offends basic fairness and risks eroding protections against repeated prosecutions.
