United States v. Robinson, 414 U.S. 218 (1973)
United States v. Robinson is a pivotal case in the realm of criminal procedure, specifically concerning the Fourth Amendment rights related to searches incident to arrest.
Is the search of an individual incident to a full custodial arrest for a traffic violation, which uncovers contraband, consistent with the Fourth Amendment?
The Fourth Amendment allows a full search of the person incident to a lawful custodial arrest, irrespective of the offense, to preserve officer safety and prevent destruction of evidence.
The Supreme Court held that the officer's search of Robinson was a lawful search incident to a custodial arrest; thus, it did not violate the Fourth Amendment.
The significance of United States v. Robinson lies in its establishment of a clear rule regarding searches incident to arrest, reinforcing the practical and predictable nature of Fourth Amendment applications in arrest scenarios. The Court maintained a balance between protection from unreasonable searches and the pragmatic needs of law enforcement. For law students, this case serves as an example of how constitutional principles are operationalized within law enforcement practices, making it crucial for understanding subsequent cases that elaborate the contours of the Fourth Amendment.
