442 U.S. 200 (1979)
Dunaway v. New York is a landmark decision in the jurisprudence of the Fourth Amendment, clarifying the limits of police authority concerning detaining individuals without probable cause.
Whether the police have the authority to detain an individual for interrogation without probable cause, thereby bypassing the protections provided by the Fourth Amendment against unreasonable seizures.
The Fourth Amendment requires that arrests be supported by probable cause, and the detention of a person for investigation without probable cause is considered an unreasonable seizure.
The Supreme Court held that the detention of Dunaway was an unreasonable seizure under the Fourth Amendment, as there was no probable cause to arrest him at the time of his detention.
Dunaway v. New York is significant as it fortified the requirement of probable cause for detentions equating to arrests, thereby extending Fourth Amendment protections. This case is critical for law students to understand the practical applications and constitutional underpinnings of lawful arrests and detentions. It reinforces the principle that protecting individual liberties must remain paramount in the face of law enforcement practices.
