United States v. MacDonald

Background

A former Army doctor, Jeffrey R. MacDonald, was investigated after his wife and two daughters were murdered at Fort Bragg in 1970. The Army initially charged him, but an internal investigation recommended dismissal and the Army dropped the charges; he was later honorably discharged. Civilian authorities reopened the inquiry, and a federal grand jury indicted him for three counts of first-degree murder in January 1975. The District Court denied his pretrial motions, including one seeking dismissal for violation of his Sixth Amendment right to a speedy trial, and the Fourth Circuit allowed an immediate appeal and ordered dismissal.

Reasoning

The Supreme Court considered whether a defendant can immediately appeal the denial of a speedy-trial dismissal before trial. The Court explained that pretrial appeals are generally barred to preserve finality and avoid piecemeal litigation. It contrasted speedy-trial claims with narrow, separable exceptions (for example, double jeopardy or bail). Because speedy-trial claims normally require factual development at trial to measure prejudice, they are not sufficiently “collateral” or final to permit immediate appeal. The Court held the court of appeals lacked jurisdiction and reversed.

Real world impact

The decision means defendants generally cannot stop a prosecution by seeking immediate appellate review of denied speedy-trial motions; they must raise the claim after trial or after the record is developed. The Supreme Court did not decide the merits of the speedy-trial claim here and returned the case to the lower court for further proceedings.
