To protect these rights, police officers are generally required to obtain an arrest warrant before a suspect can be arrested or a search warrant before a suspect or his property can be searched. One of the most highly protected areas under the Fourth Amendment is an individual’s home, and courts are extra cautious to ensure an individual’s rights are not infringed upon in his or her home. Two seminal Supreme Court decisions discuss the warrant requirements to arrest suspects in private dwellings. In New York v. Payton, the Supreme Court ruled that police can lawfully enter a suspect’s home with a valid arrest warrant and a reasonable belief that the suspect is inside. A later case, Steagald v. United States, held that the rule in Payton did not extend to the homes of third parties and held a search warrant, in addition to the arrest warrant, is necessary to enter a third party’s home. What did not appear to be answered was who has standing to challenge such a violation.
