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 getting a warrant because their entry "was plainly reasonable under the circumstances." In ruling the officers' entry was supported by exigency, the Court cited Mincey v. Arizona , 437 U.S. 385 (1978), 393–394:
[W]arrants are generally required to search a person’s home or his person unless 'the exigencies of the situation' make the needs of law enforcement so compelling that the warrantless search is objectively reasonable under the Fourth Amendment." ... One exigency obviating the requirement of a warrant is the need to assist persons who are seriously injured or threatened with such injury. ... Accordingly, law enforcement officers may enter a home without a warrant to render emergency assistance to an injured occupant or to protect an occupant from imminent injury. Mincey, supra, at 392; see also Georgia v. Randolph , 547
The court found that "the officers had an objectively reasonable basis for believing both that the injured adult might need help and that the violence in the kitchen was just beginning."
"Knock and announce" rule
The Court found that "the manner of the officers' entry was also reasonable." The court found that after seeing the punch, one officer opened the screen door to the kitchen and yelled in "police." Upon nobody hearing him, he stepped into the kitchen and then announced himself again, which prompted the tumult to subside. The Court ruled that:
- ...the officer's announcement of his presence was at least equivalent to a knock on the screen door. Indeed, it was probably the only option that had even a chance of rising above the din. Under these circumstances, there was no violation of the Fourth Amendment’s knock-and-announce rule.
Also, the Court ruled that once the officers announced their presence, they were free to enter the house to deal with the tumult, as it would be pointless to stand at the door waiting for a response while people brawled inside.
Search and seizure is a procedure used in many civil law and common law legal systems by which police or other authorities and their agents, who, suspecting that a crime has been committed, commence a search of a person's property and confiscate any relevant evidence found in connection to the crime.
In criminal procedure law of the United States, an exigent circumstance allows law enforcement to enter a structure without a search warrant, or if they have a "knock and announce" warrant, allows them to enter without knocking and waiting for the owner's permission to enter. It must be a situation where people are in imminent danger, evidence faces imminent destruction, or a suspect's escape is imminent. Once entry is obtained, the plain view doctrine applies, allowing the seizure of any evidence or contraband discovered in the course of actions consequent upon the exigent circumstances.
Knock-and-announce, in United States law criminal procedure, is an ancient common law principle, incorporated into the Fourth Amendment, which requires law enforcement officers to announce their presence and provide residents with an opportunity to open the door prior to a search.
Section 8 of the Canadian Charter of Rights and Freedoms protects against unreasonable search and seizure. This right provides those in Canada with their primary source of constitutionally enforced privacy rights against unreasonable intrusion from the state. Typically, this protects personal information that can be obtained through searching someone in pat-down, entering someone's property or surveillance.
In United States law, the Aguilar–Spinelli test was a judicial guideline set down by the U.S. Supreme Court for evaluating the validity of a search warrant or a warrantless arrest based on information provided by a confidential informant or an anonymous tip. The Supreme Court abandoned the Aguilar–Spinelli test in Illinois v. Gates, 462 U.S. 213 (1983), in favor of a rule that evaluates the reliability of the information under the "totality of the circumstances." However, Alaska, Hawaii, Massachusetts, New York, Vermont, Oregon, and Washington have retained the Aguilar–Spinelli test, based on their own state constitutions.
Georgia v. Randolph, 547 U.S. 103 (2006), is a case in which the U.S. Supreme Court held that without a search warrant, police had no constitutional right to search a house where one resident consents to the search while another resident objects. The Court distinguished this case from the "co-occupant consent rule" established in United States v. Matlock, 415 U.S. 164 (1974), which permitted one resident to consent in absence of the co-occupant.
Hudson v. Michigan, 547 U.S. 586 (2006), is a United States Supreme Court case in which the Court held that a violation of the Fourth Amendment requirement that police officers knock, announce their presence, and wait a reasonable amount of time before entering a private residence does not require suppression of the evidence obtained in the ensuing search.
Search incident to a lawful arrest, commonly known as search incident to arrest (SITA) or the Chimel rule, is a U.S. legal principle that allows police to perform a warrantless search of an arrested person, and the area within the arrestee’s immediate control, in the interest of officer safety, the prevention of escape, and the preservation of evidence.
Welsh v. Wisconsin, 466 U.S. 740 (1984), was a 1983 case before the US Supreme Court determining that a warrantless home arrest without exigent circumstances violates the Fourth Amendment protection against unlawful search and seizure.
Schmerber v. California, 384 U.S. 757 (1966), was a landmark United States Supreme Court case in which the Court clarified the application of the Fourth Amendment's protection against warrantless searches and the Fifth Amendment right against self-incrimination for searches that intrude into the human body. Until Schmerber, the Supreme Court had not yet clarified whether state police officers must procure a search warrant before taking blood samples from criminal suspects. Likewise, the Court had not yet clarified whether blood evidence taken against the wishes of a criminal suspect may be used against that suspect in the course of a criminal prosecution.
The law of search and seizure in Pennsylvania is controlled by both the United States Constitution and the broader protections of the Pennsylvania Constitution. This article is concerned only with the protections provided by the Pennsylvania Constitution.
Ronald E. Nehring was a justice of the Utah Supreme Court. He was appointed to the court in 2003 by Utah Governor Michael Leavitt, and he retired in 2015.
Kentucky v. King, 563 U.S. 452 (2011), was a decision by the US Supreme Court, which held that warrantless searches conducted in police-created exigent circumstances do not violate the Fourth Amendment as long as the police did not create the exigency by violating or threatening to violate the Fourth Amendment.
Missouri v. McNeely, 569 U.S. 141 (2013), was a case decided by United States Supreme Court, on appeal from the Supreme Court of Missouri, regarding exceptions to the Fourth Amendment to the United States Constitution under exigent circumstances. The United States Supreme Court ruled that police must generally obtain a warrant before subjecting a drunken-driving suspect to a blood test, and that the natural metabolism of blood alcohol does not establish a per se exigency that would justify a blood draw without consent.
R v Fearon, 2014 SCC 77 is a leading section 8 Canadian constitutional law case, concerning the constitutionality of warrantless law enforcement searches of the contents of a cell phone incident to arrest.
United States v. Watson, 423 U.S. 411 (1976), was a case decided by the Supreme Court of the United States that decided that a warrantless arrest in public and consenting to a vehicle search did not violate the Fourth Amendment.
Birchfield v. North Dakota, 579 U.S. 438 (2016) is a case in which the Supreme Court of the United States held that the search incident to arrest doctrine permits law enforcement to conduct warrantless breath tests but not blood tests on suspected drunk drivers.
Mitchell v. Wisconsin, 588 U.S. ___ (2019), is a United States Supreme Court case in which the Court held that "when a driver is unconscious and cannot be given a breath test, the exigent-circumstances doctrine generally permits a blood test without a warrant."
Caniglia v. Strom, 593 U.S. ___ (2021), was a United States Supreme Court case related to the Fourth Amendment to the United States Constitution's "community caretaking" exception.
Lange v. California, 594 U.S. ___ (2021), was a United States Supreme Court case involving the exigent circumstances requirement related to the Fourth Amendment to the United States Constitution. The Court ruled unanimously that the warrantless entry into a home by police in pursuit of a misdemeanant is not unequivocally justified.
