R v Godoy, [1999] 1 S.C.R. 311 is a leading Supreme Court of Canada decision regarding the scope of police powers to enter into private dwellings without a warrant in order to protect lives. The Court affirmed that police have a common law duty to protect lives and that an anonymous 911 call is sufficient to invoke that duty, consequently, the police were justified in forcibly entering into the private home.
On June 1, 1992, a 911 operator received an "unknown trouble" call where the phone was disconnected before the operator heard any voice. The call was traced to Vincent Godoy's house and four police officers were dispatched to his house. The policy of the police is to treat "unknown trouble" calls as high priority. The officers talked with Godoy who told them that there was no problem. One officer asked if they could come inside. Godoy tried to close the door but the officer put his foot in the door and they all entered. The officers found a battered woman sobbing. They arrested Godoy for assault.
In the Ontario Court of Appeal, the court found that the police acted validly based on their common law duty to prevent serious injury and protect lives. The Supreme Court upheld the Court of Appeal's decision.
Chief Justice Lamer, for the Court, found that police possessed a general duty to protect lives even outside of criminal situations. Where there are reasonable and probable grounds the police are allowed entering a private dwelling in order to fulfill their duty. Here, the police could not have had reasonable and probable grounds based solely on the phone call. However, once they investigated further they were able to establish a reasonable and probable ground which allowed them to enter.

The Fourth Amendment to the United States Constitution is part of the Bill of Rights. It prohibits unreasonable searches and seizures and sets requirements for issuing warrants: warrants must be issued by a judge or magistrate, justified by probable cause, supported by oath or affirmation, and must particularly describe the place to be searched and the persons or things to be seized.
In United States criminal law, probable cause is the standard by which police authorities have reason to obtain a warrant for the arrest of a suspected criminal or the issuing of a search warrant. There is no universally accepted definition or formulation for probable cause. One traditional definition, which comes from the U.S. Supreme Court's 1964 decision Beck v. Ohio, is when "whether at [the moment of arrest] the facts and circumstances within [an officer's] knowledge and of which they had reasonably trustworthy information [are] sufficient to warrant a prudent [person] in believing that [a suspect] had committed or was committing an offense."
Terry v. Ohio, 392 U.S. 1 (1968), was a landmark U.S. Supreme Court decision in which the court ruled that it is constitutional for American police to "stop and frisk" a person they reasonably suspect to be armed and involved in a crime. Specifically, the decision held that a police officer does not violate the Fourth Amendment to the U.S. Constitution's prohibition on unreasonable searches and seizures when questioning someone even though the officer lacks probable cause to arrest the person, so long as the police officer has a reasonable suspicion that the person has committed, is committing, or is about to commit a crime. The court also ruled that the police officer may perform a quick surface search of the person's outer clothing for weapons if they have reasonable suspicion that the person stopped is "armed and presently dangerous." This reasonable suspicion must be based on "specific and articulable facts," and not merely upon an officer's hunch.
In common law, the curtilage of a house or dwelling is the land immediately surrounding it, including any closely associated buildings and structures, but excluding any associated "open fields beyond". In feudal times every castle with its dependent buildings was protected by a surrounding wall, and all the land within the wall was termed the curtilage. The term excludes any closely associated buildings, structures, or divisions that contain the separate intimate activities of their own respective occupants, with those occupying residents being persons other than those residents of the house or dwelling of which the building is associated.
R v Mann is a 2004 decision of the Supreme Court of Canada.
R v Feeney, [1997] 2 S.C.R. 13 is a leading decision of the Supreme Court of Canada on the right, under section 8 of the Canadian Charter of Rights and Freedoms against unreasonable search and seizure. The Court held that the police are not permitted to enter into someone's house without a search warrant.
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.
In United States constitutional law, expectation of privacy is a legal test which is crucial in defining the scope of the applicability of the privacy protections of the Fourth Amendment to the U.S. Constitution. It is related to, but is not the same as, a right to privacy, a much broader concept which is found in many legal systems. Overall, expectations of privacy can be subjective or objective.
South Dakota v. Opperman, 428 U.S. 364 (1976), elaborated on the community caretaking doctrine. Under the Fourth Amendment, "unreasonable" searches and seizures are forbidden. In addition to their law-enforcement duties, the police must engage in what the court has termed a community caretaking role, including such duties as removing obstructions from roadways to ensure the free flow of traffic. When the police act in this role, they may inventory cars they have seized without "unreasonably" searching those cars.
Wilson v. Arkansas, 514 U.S. 927 (1995), is a United States Supreme Court decision in which the Court held that the traditional, common-law-derived "knock and announce" rule for executing search warrants must be incorporated into the "reasonableness" analysis of whether the actual execution of the warrant is/was justified under the 4th Amendment. The high court thus ruled that the old "knock and announce" rule while not a hard requirement, was also not a dead letter.
Miazga v Kvello Estate, 2009 SCC 51 is a leading decision of the Supreme Court of Canada on how the tort of malicious prosecution applies to Crown attorneys and other public prosecutors. Specifically, the court held that there is no requirement for a public prosecutor to have a subjective belief that an accused person is actually guilty. Nor can there be a presumption of malice from a lack of reasonable and probable grounds.
R v Kang-Brown, [2008] 1 S.C.R. 456, 2008 SCC 18, is a constitutional decision by the Supreme Court of Canada on the limits of police powers for search and seizure. The Court found that police do not have the right to perform a sniffer-dog search of public spaces when such search is not specifically authorized by statute. In this case, a suspect's section 8 rights under the Canadian Charter of Rights and Freedoms ("Charter") were violated when a police officer stopped him at a bus station and sniffer-dog searched his bag finding drugs in his possession.
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.
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.
Navarette v. California, 572 U.S. 393 (2014), was a case in which the United States Supreme Court clarified when police officers may make arrests or conduct temporary detentions based on information provided by anonymous tips. In 2008, police in California received a 911 call that a pickup truck was driving recklessly along a rural highway. Officers spotted a truck matching the description provided in the 911 call and followed the truck for five minutes, but did not observe any suspicious behavior. Nevertheless, officers conducted a traffic stop and discovered 30 pounds (14 kg) of marijuana in the truck. At trial, the occupants of the car argued that the traffic stop violated the Fourth Amendment of the United States Constitution, because the tip was unreliable, and officers did not personally observe criminal activity. Writing for a majority of the Court, Justice Clarence Thomas held that the 911 call was reliable, and that officers need not personally observe criminal activity when acting upon information provided by an anonymous 911 call.
Lozman v. City of Riviera Beach, 585 U.S. ___ (2018), is a case in which the United States Supreme Court decided that the mere existence of probable cause for an arrest did not bar the plaintiff's First Amendment retaliatory arrest claim, but deferred consideration of the broader question of when it might. The case concerned a 42 U.S.C. § 1983 lawsuit filed against Riviera Beach by Fane Lozman, who had been arrested while criticizing local politicians during the public comments section of a City Council meeting. The city argued that under Hartman v. Moore he could not sue for retaliation, as they had probable cause to arrest him for the offense of disturbing a lawful assembly. Lozman conceded that they had probable cause, but argued that Hartman, a case about retaliatory prosecutions, did not extend to retaliatory arrests, and that instead Mt. Healthy City School District Board of Education v. Doyle allowed his suit.
Johnson v. United States, 333 U.S. 10 (1948), was a significant United States Supreme Court decision addressing search warrants and the Fourth Amendment. In this case, where federal agents had probable cause to search a hotel room but did not obtain a warrant, the Court declared the search was "unreasonable."
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.
R v Golden, 2001 SCC 83 is a landmark decision of the Supreme Court of Canada on limitations to the power of police officers to perform strip searches. The Court held that the common law rule allowing peace officers to perform warrantless searches incident to arrest must be limited in relation to strip searches, citing their heightened intrusiveness and impact on the Charter protected privacy interests of the accused.
R v Stairs, 2022 SCC 11 is a constitutional rights decision of the Supreme Court of Canada. The Court established new standards for searches of a person's home after they have been arrested. At issue in the case was whether the traditional common law power of Search Incident to Arrest, which allows police officers to engage in warrantless searches of lawfully arrested persons, was compliant with section 8 of the Charter of Rights and Freedoms as it related to searches of the home.
