Michael v. United States

1981-12-07

Headline: Court refuses to review dispute over warrantless installation of vehicle tracking 'beepers,' leaving Fifth Circuit rule allowing reasonable-suspicion installations in place while appeals courts remain divided.

Holding: The Court denied the petition for review, leaving the Fifth Circuit’s decision that reasonable suspicion can justify a warrantless beeper installation in place and leaving circuit conflicts unresolved.

Real World Impact:

Leaves split among federal appeals courts unresolved.
Fifth Circuit rule allowing beepers on reasonable suspicion remains effective there.
Law enforcement in different regions may follow different beeper rules.

Summary

Background

A man’s rented van had an electronic tracking device, or “beeper,” placed on its exterior by Drug Enforcement Administration agents without a warrant. The district court suppressed the evidence. The Fifth Circuit, sitting en banc, held that installing the beeper was permissible and that only reasonable suspicion — not probable cause — was needed. The Solicitor General opposed review, saying the issue might become moot if the defendant is acquitted.

Reasoning

The core question was whether agents may install a tracking beeper on a vehicle without a warrant and whether reasonable suspicion is enough. The Fifth Circuit said yes, citing a limited expectation of privacy in cars, minimal intrusion from the device, and the government’s interest in fighting illegal drug manufacture. The opinion notes that other appeals courts disagree: the First Circuit requires probable cause for attachment and monitoring, and the Sixth Circuit requires a warrant and probable cause. Some circuits have avoided deciding the issue because of consent, judicial authorization, or exigent circumstances in particular cases.

Real world impact

By declining to take the case, the Supreme Court left the Fifth Circuit’s rule intact in that region and left the split among federal appeals courts unresolved. That means law enforcement and defendants may face different rules depending on the appeals court handling a case. The denial is not a final ruling on the constitutional question and could be revisited later.

Dissents or concurrances

Justice White, joined by Justices Brennan and Powell, dissented from the denial and would have granted review to resolve the clear and recurring conflict among the circuits, echoing prior concerns by Justice Rehnquist.
