Cameron Miranda
The Fourth Amendment of the US Constitution protects people from unlawful government searches and seizures. In the US, law enforcement officers are required to obtain a warrant before searching a person, their property, or seizing their personal effects. However, there are exceptions to this rule, such as when there is probable cause to arrest a person or when a person is being unlawfully restrained. In some cases, a third party with possessory rights to a property may give consent for law enforcement to search it. This is a complex area, as it implicates privacy rights, and the law is still developing in this area, particularly with the increasing use of digital storage technologies.

What You'll Learn
Third-party consent
In the United States, the Fourth Amendment protects people from unreasonable searches and seizures, and it requires warrants to be supported by probable cause. However, consent searches are an exception to the warrant requirement. While consent searches are typically voluntary, the law does not mandate that law enforcement officers disclose the voluntary nature of consent to the individual. The courts have ruled that evidence obtained through consent searches, even by undercover officers, can be used in criminal trials.
Historically, third-party consent was deemed sufficient when the third party had "common authority over or other sufficient relationship to the premises or effects sought to be inspected." Notable cases include United States v. Matlock (1974), where a woman consented to a search of a shared bedroom, and Frazier v. Cupp (1969), where a joint user of a duffel bag consented to a search. However, there are also cases where third-party consent was not sufficient, such as Chapman v. United States (1961) and Stoner v. California (1964).
More recently, the legal interpretation has evolved, and actual common authority is no longer a strict requirement. Instead, it is sufficient if the searching officer had a reasonable but mistaken belief that the third party had the authority to consent to the search. This evolution in interpretation is illustrated in cases like Fernandez v. California (2014), where the consent of one co-occupant was deemed sufficient despite the objection of another co-occupant who was arrested and removed from the premises.
It is important to note that consent must be truly voluntary and not obtained through coercion or deception. Courts will evaluate the circumstances under which consent was given to determine its validity. Additionally, the withdrawal of consent must be clear and unequivocal, although there are exceptions, such as airport screenings and prison visitor searches, where consent cannot be revoked once the search has begun.
The acquisition of third-party records by law enforcement is another aspect of third-party consent. This can include medical records, location data, and other sensitive information. While this practice is not new, the increasing prevalence of digital storage technologies has heightened concerns about privacy and the need for consistent regulations. Legislatures, courts, and administrative agencies are grappling with striking a balance between law enforcement needs and protecting privacy and freedom of expression.

Search warrants
A search warrant is a warrant signed by a judge or magistrate authorising a law enforcement officer to conduct a search of a certain person, a specified place, or an automobile for criminal evidence. Search warrants are usually a prerequisite for a search and are designed to protect individuals' reasonable expectation of privacy against unreasonable government physical trespass or other intrusion. Search warrants originate from the Fourth Amendment of the US Constitution, which protects people from unlawful government searches and seizures.
The Fourth Amendment states:
> "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrant shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
In the case of third-party premises, police officers can search the place of a person who is not suspected of a crime. A third party with possessory rights to the property may have the authority to consent to a search, but this consent must be given voluntarily. If consent is given under threats, it is invalid.
In the case of electronically stored information, Rule 41(e)(2)(A) of the Federal Rules of Criminal Procedure authorises police officers to search "electronic storage media" or "copying of electronically stored information" with a search warrant. Officers can copy seized material for later review.

Exigent circumstances
Another common exigent circumstance is when officers are in hot pursuit of a fleeing suspect, and they need to enter a residence to continue the pursuit. Additionally, exigent circumstances can apply when officers have probable cause to believe that evidence will be destroyed or removed during the time it takes to obtain a warrant.
It's important to note that the interpretation and application of exigent circumstances can vary across jurisdictions. Courts and law enforcement agencies must carefully balance the need for warrantless searches in exigent circumstances with individuals' privacy rights and freedoms of speech, association, and commerce.

Privacy considerations
The Fourth Amendment of the U.S. Constitution protects people from unlawful government searches and seizures, ensuring their right to privacy. Any search warrant must be supported by probable cause and must specifically describe the place to be searched and the items to be seized. Courts, legislatures, and administrative agencies are tasked with determining when law enforcement access to sensitive information, such as medical records and location data, should be allowed.
The level of privacy protection depends on the type of information and the institution holding it. Information maintained by third parties can be classified as highly private, moderately private, minimally private, or not private. This determination considers the current and evolving technology and the extent to which the initial transfer of information to a third party was voluntary.
The privacy considerations also extend to the data and records held by both private and public databases. These databases contain extensive personal information about individuals, most of whom are not involved in any unlawful activities. The challenge lies in developing principles to regulate access to this information, as the interests at stake vary depending on the nature of the information and expectations of its disclosure.
Furthermore, individuals have a legitimate expectation of privacy regarding their sensitive information held by third parties, such as banks, hospitals, and cellular phone providers. Courts have acknowledged that obtaining certain information, such as emails and long-term location tracking, may constitute a search under the Fourth Amendment. Therefore, a balance must be struck between law enforcement's need for access and the privacy rights of individuals.

Lawful arrest
The Fourth Amendment of the US Constitution protects people from unlawful government searches and seizures. Search warrants, which are usually required for a search to be lawful, must be supported by probable cause.
Law enforcement officers can search a third party's premises or vehicle incident to a lawful arrest. This includes the arrestee's home, their vehicle, and containers found within the vehicle. Officers can also search areas within the arrestee's immediate control to alleviate any threat posed by the arrestee, and this can be extended to a "protective sweep" of the entire premises if officers have a "reasonable belief" that there may be a threat posed by "unseen third parties in the house".
However, a search or seizure without a warrant as an incident to a lawful arrest is a strictly limited right. For example, in Trupiano v. United States, the Court reversed a conviction because the officers had time to obtain a search warrant but did not do so.
In the case of Birchfield v. North Dakota, the Court examined whether compulsory breath and blood tests administered to determine the blood alcohol concentration (BAC) of a driver arrested for suspected drunk driving were unreasonable under the Fourth Amendment. The Court concluded that warrantless breath tests incident to arrests for drunk driving are permitted because the privacy impact is slight, whereas blood tests raise more serious privacy concerns.
In summary, while a lawful arrest can provide a basis for law enforcement to search a third party's premises or vehicle, it is not a blanket authorisation, and the specific circumstances and scope of the search will be critical factors in determining its lawfulness.

Frequently asked questions
A search warrant is a warrant signed by a judge or magistrate authorizing a law enforcement officer to conduct a search on a certain person, a specified place, or an automobile for criminal evidence.
Law enforcement can search a third party without a warrant if they have the consent of the owner or a person with possessory rights to the property. In the case of a home with multiple residents, the consent of one resident may be enough, but not if another resident is present and objects to the search.
Exigent circumstances are situations where there is probable cause to fear the imminent destruction of evidence or the suspect's escape. In such cases, law enforcement may be able to conduct a warrantless search.
Yes, law enforcement can access third-party records, but this can infringe on the privacy of those whose information is contained in the records. The federal government and all fifty states regulate government access to and use of certain types of record information.
