Coolidge v. New Hampshire

1971-06-21

Headline: Court invalidates a prosecutor-issued search warrant and blocks car evidence, ruling that an investigating attorney cannot act as a neutral magistrate and limiting police seizures of parked vehicles without a judge.

Holding: The Court held the warrant invalid because the State Attorney General was the active investigator and not a neutral judge, and therefore the seizure and later searches of the parked car were unconstitutional and its evidence barred.

Real World Impact:

Makes warrants invalid if issued by investigators acting as magistrates.
Bars use of evidence from planned seizures of parked vehicles without a neutral judge.
Allows items voluntarily handed over by relatives to be admitted.

Summary

Background

A 14-year-old girl was found murdered and police investigated widely. Officers questioned Edward Coolidge and later took him in for further testing. While he was at the station, two officers spoke with his wife, who voluntarily handed over four guns and several garments. Weeks later the State Attorney General, who had led the investigation and would prosecute the case, signed a warrant to seize Coolidge’s 1951 Pontiac, which officers towed from his driveway and searched. Vacuum sweepings from the car and tests on the gun and clothes were admitted at trial and Coolidge was convicted.

Reasoning

The central question was whether the warrant and the subsequent seizures were constitutional. The Court said a magistrate must be “neutral and detached,” and the Attorney General who supervised the probe could not be treated that way, so the warrant was invalid. The Court also rejected the State’s fallback arguments: the search could not be justified as incident to arrest, by the automobile exception for fleeting searches, or by a plain-view rule, because the police planned the seizure and had time to get a neutral warrant. The Court found that the guns and clothes the wife handed over were admissible because she produced them voluntarily and not as an agent of the police.

Real world impact

The decision requires law enforcement to get warrants from impartial judicial officers rather than rely on investigators acting as magistrates. Evidence from planned seizures of parked vehicles or other items known in advance can be suppressed if proper neutral review is lacking. Voluntary family handovers of items remain likely admissible, depending on the circumstances.

Dissents or concurrances

Several Justices dissented or filed separate opinions arguing for broader police authority. Some said the car seizure and later searches were reasonable and should be admitted; one Justice argued the Fourth Amendment does not itself require excluding such evidence. Another Justice urged rethinking the Court’s exclusionary-rule decisions.
