Summary
In Griffin v. Wisconsin, the Supreme Court upheld a warrantless search of a probationer's home under a Wisconsin regulation requiring reasonable grounds and supervisor approval. The Court treated probation supervision as a special need beyond ordinary law enforcement, allowing a limited departure from the usual warrant and probable-cause rules.
Legal Issue
Does the Fourth Amendment allow a warrantless search of a probationer's home, based on reasonable grounds and authorized by a probation regulation, without probable cause or a warrant?
Holding
Yes. The Supreme Court held that the search was reasonable under the Fourth Amendment because it was conducted under a valid Wisconsin regulation responding to the special needs of the probation system. Probation supervision may justify departures from the ordinary warrant and probable-cause requirements when the regulation requires reasonable grounds and supervisory approval.
Rule of Law
Probation does not erase the Fourth Amendment, but it can change what is reasonable. Under a valid probation rule, officers may search a probationer's home without a warrant when there are reasonable grounds tied to supervision.
