Date of Decision

21 June 1990


A warrantless entry by police officers into a person's home is not invalid under the Fourth Amendment if the police officers reasonably--but mistakenly--believe that a third party has the authority to give consent for the entry.


The Rodriguez decision made it possible for police to enter a person's home without a warrant, even if they are relying on the consent of a person who does not have authority to give consent for the entry. The decision has been criticized by many legal analysts for diluting Fourth Amendment protections against invasion by police
