McGuire v. United States

Background

McGuire, charged under the National Prohibition Act for possessing intoxicating liquor, was searched after a warrant issued by a federal commissioner. Revenue agents found several gallons of liquor. They destroyed most of it without court order but kept one quart of whiskey and one quart of alcohol as evidence. At trial those retained samples were admitted over McGuire’s objection. The Court of Appeals asked two questions about officer misconduct and evidence admissibility.

Reasoning

The Court asked whether destroying seized liquor made the officers trespassers from the start and whether that would bar the remaining samples. The opinion says the officers’ destruction was illegal, but the old rule of “trespass ab initio” is a civil fiction not meant to prevent the Government from using evidence. The Court distinguished officer liability from the Government’s right to evidence and held that admitting the preserved samples did not violate the Constitution. The answer to the admissibility question was No.

Real world impact

The decision means prosecutions can proceed using lawfully seized items still in the Government’s possession even if officers later act wrongly. It preserves the Government’s access to evidence while leaving open personal penalties for officers who destroy property. Defendants still have constitutional protections against unlawful invasions, but officer misconduct will not automatically force exclusion of otherwise properly seized evidence. It limits the reach of an old legal fiction so abusive conduct by officers does not automatically nullify prosecutions.

Dissents or concurrances

Justice Butler joined the Court’s result in a short concurrence, agreeing the samples should be admissible.
