Lewis v. United States

Background

A man who sold marijuana from his apartment arranged two sales with an undercover federal agent who falsely identified himself as “Jimmy.” On December 3 and December 17, the agent called, was invited into the seller’s home, paid $50 each time, and received packages containing five and six small bags of marijuana. The seller was arrested, a judge denied a pretrial motion to suppress the evidence, a trial court convicted him, and a federal appeals court affirmed the convictions.

Reasoning

The Court asked whether the agent’s lying about his identity and entry into the home to buy drugs violated the Fourth Amendment’s protection of the home. The majority held it did not because the seller voluntarily invited the buyer into the home to conduct an illegal sale, and the agent only did what any private purchaser could do — accept the invitation, pay, and take the drugs. The Court distinguished earlier cases where officers secretly ransacked rooms, forcibly seized items, or eavesdropped; those facts involved intrusive searches or unwanted listening, which are different from an invited sale.

Real world impact

This decision allows law enforcement to use undercover buyers who misrepresent their identity when a suspect invites them in to buy illegal goods, and it upholds the admissibility of such purchases as evidence. At the same time, the Court made clear this does not authorize broad, general searches, secret ransacking, or covert eavesdropping inside a home.

Dissents or concurrances

Justice Brennan (joined by Justice Fortas) wrote separately, agreeing with the result but emphasizing that the apartment lost privacy protection only to the extent it was opened for business transactions with customers.
