Brigham City v. Stuart, 547 U.S. 398 (2006), is a United States Supreme Court case involving the exigent circumstances exception to the Fourth Amendment's warrant requirement. The Court ruled that police may enter a home without a warrant if they have an objectively reasonable basis for believing that an occupant is or is about to be seriously injured. The case involved the arrest of four adults seen restraining a juvenile, who punched one of the adults who was restraining him. The trial court granted the defendants' motion to dismiss, arguing that the warrantless entry was not supported by exigent circumstances; the Utah Court of Appeals and Utah Supreme Court both affirmed the trial court's ruling. However, the U.S. Supreme Court reversed and remanded the case on May 22, 2006. Background On July 23, 2001, at about 3:00 AM, four Brigham City police officers were dispatched to a loud house party. At the front door, the officers determined that knocking would not be productive and made their way down the driveway alongside the house to investigate. Through a slat fence they saw two minors drinking and entered the backyard, having probable cause to do so. While in the backyard, the officers saw a fight inside the house, which appeared to be four adults restraining a juvenile. At one point, the juvenile broke free and struck one of the occupants of the house in the nose with his hand. Two officers opened the screen door and "hollered" to identify themselves, but the occupants didn't notice. After entering the house, one officer shouted again to identify himself, this time alerting the occupants. The occupants then became upset at the presence of the officers in the residence without permission. The officers arrested the adults and charged them with contributing to the delinquency of a minor, disorderly conduct, and intoxication. The defendants filed a motion to suppress with the trial court. The trial court sided with the defendants, and the city twice appealed to the Utah Court of Appeals and the Utah Supreme Court, which both affirmed the trial court's ruling. Opinion of the Court The Supreme Court reversed the decision of the Utah Supreme Court, in a unanimous opinion delivered by Chief Justice John Roberts. Justice John Paul Stevens delivered a separate concurring opinion. Exigency The Court ruled that the officers' warrantless entry into the home was justified under the emergency aid exception to
