The Fourth Amendment to the United States Constitution is part of the Bill of Rights. It prohibits unreasonable searches and seizures. In addition, it 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.
A search warrant is a court order that a magistrate or judge issues to authorize law enforcement officers to conduct a search of a person, location, or vehicle for evidence of a crime and to confiscate any evidence they find. In most countries, a search warrant cannot be issued in aid of civil process.
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. It is also the standard by which grand juries issue criminal indictments. The principle behind the standard is to limit the power of authorities to perform random or abusive searches, and to promote lawful evidence gathering and procedural form during criminal arrest and prosecution. The standard also applies to personal or property searches.
The Electronic Communications Privacy Act of 1986 (ECPA) was enacted by the United States Congress to extend restrictions on government wire taps of telephone calls to include transmissions of electronic data by computer, added new provisions prohibiting access to stored electronic communications, i.e., the Stored Communications Act, and added so-called pen trap provisions that permit the tracing of telephone communications . ECPA was an amendment to Title III of the Omnibus Crime Control and Safe Streets Act of 1968, which was primarily designed to prevent unauthorized government access to private electronic communications. The ECPA has been amended by the Communications Assistance for Law Enforcement Act (CALEA) of 1994, the USA PATRIOT Act (2001), the USA PATRIOT reauthorization acts (2006), and the FISA Amendments Act (2008).
Email privacy is a broad topic dealing with issues of unauthorized access and inspection of electronic mail. This unauthorized access can happen while an email is in transit, as well as when it is stored on email servers or on a user computer. In countries with a constitutional guarantee of the secrecy of correspondence, whether email can be equated with letters and has legal protection from all forms of eavesdropping comes under question because of the very nature of email. This is especially important as relatively more communication occurs via email compared to via postal mail.
Public records are documents or pieces of information that are not considered confidential and generally pertain to the conduct of government.
Section 8 of the Canadian Charter of Rights and Freedoms provides everyone in Canada with protection against unreasonable search and seizure. This right provides Canadians 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.
The USA PATRIOT Act was passed by the United States Congress in 2001 as a response to the September 11, 2001 attacks. It has ten titles, each containing numerous sections. Title II: Enhanced Surveillance Procedures granted increased powers of surveillance to various government agencies and bodies. This title has 25 sections, with one of the sections containing a sunset clause which sets an expiration date, December 31, 2005, for most of the title's provisions. This was extended twice: on December 22, 2005 the sunset clause expiration date was extended to February 3, 2006 and on February 2 of the same year it was again extended, this time to March 10.

A national security letter (NSL) is an administrative subpoena issued by the United States government to gather information for national security purposes. NSLs do not require prior approval from a judge. The Stored Communications Act, Fair Credit Reporting Act, and Right to Financial Privacy Act authorize the United States government to seek such information that is "relevant" to authorized national security investigations. By law, NSLs can request only non-content information, for example, transactional records and phone numbers dialed, but never the content of telephone calls or e-mails.
United States v. Grubbs, 547 U.S. 90 (2006), was a case decided by the Supreme Court of the United States involving the constitutionality of "anticipatory" search warrants under the Fourth Amendment to the United States Constitution. The Court ruled that such warrants, which are issued in advance of a "triggering condition" that makes them executable, are constitutional and do not need to describe that condition on their face.
In common law jurisdictions, legal professional privilege protects all communications between a professional legal adviser and his or her clients from being disclosed without the permission of the client. The privilege is that of the client and not that of the lawyer.
Zurcher v. Stanford Daily, 436 U.S. 547 (1978), is a United States Supreme Court case from 1978 in which The Stanford Daily, a student newspaper at Stanford University, was searched by police after they suspected the paper to be in possession of photographs of a demonstration that took place at the university's hospital in April 1971. The Stanford Daily filed a suit claiming that under the protection of the First and Fourth Amendments of the Constitution, the warrants were unconstitutional and that the searches should have fallen under the context of subpoenas. The Supreme Court ruled against The Stanford Daily; however, Congress later passed the Privacy Protection Act of 1980, which provides additional protections against searches and seizures to the press and individuals who disseminate information to the public, unless that individual is suspected of a crime or a life-threatening situation is present.
The Stored Communications Act is a law that addresses voluntary and compelled disclosure of "stored wire and electronic communications and transactional records" held by third-party internet service providers (ISPs). It was enacted as Title II of the Electronic Communications Privacy Act of 1986 (ECPA).
State v. Reid, 194 N.J. 386, 954 A.2d 503, was a criminal court case in which the New Jersey Supreme Court ruled that Internet service provider (ISP) subscribers have a reasonable expectation of privacy in the identifying information they provide to ISPs. This case has helped place New Jersey at the forefront of the states committed to providing their residents with broader privacy protections than those available under federal law.
United States v. Warshak, 631 F.3d 266 is a criminal case decided by the United States Court of Appeals for the Sixth Circuit holding that government agents violated the defendant's Fourth Amendment rights by compelling his Internet service provider (ISP) to turn over his emails without first obtaining a search warrant based on probable cause. However, constitutional violation notwithstanding, the evidence obtained with these emails was admissible at trial because the government agents relied in good faith on the Stored Communications Act (SCA). The court further declared that the SCA is unconstitutional to the extent that it allows the government to obtain emails without a warrant.
Doe v. Shurtleff, 628 F.3d 1217, was a United States Court of Appeals for the Tenth Circuit case assessing the constitutionality of Utah Code Ann. § 77-27-21.5, a law that requires sex offenders to register their internet identifiers with the state in order to "assist in investigating kidnapping and sex-related crimes, and in apprehending offenders." In this case, a convicted sex offender, appearing anonymously as John Doe, appealed a decision by the United States District Court for the District of Utah to vacate an order enjoining the enforcement of Utah Code Ann. § 77-27-21.5. Even though Doe did not dispute the state's interest in enacting such a statute, he believed that the statute's enforcement ran afoul of his:
In Maryland v. King, 569 U.S. 435 (2013), the United States Supreme Court decided that a cheek swab of an arrestee's DNA is comparable to fingerprinting and therefore, a legal police booking procedure that is reasonable under the Fourth Amendment.
The third-party doctrine is a United States legal doctrine that holds that people who voluntarily give information to third parties—such as banks, phone companies, internet service providers (ISPs), and e-mail servers—have "no reasonable expectation of privacy." A lack of privacy protection allows the United States government to obtain information from third parties without a legal warrant and without otherwise complying with the Fourth Amendment prohibition against search and seizure without probable cause and a judicial search warrant.
Carpenter v. United States, No. 16-402, 585 U.S. ____ (2018), was a landmark United States Supreme Court case concerning the privacy of historical cell site location information (CSLI). The Court held, in a 5–4 decision authored by Chief Justice Roberts, that the government violates the Fourth Amendment to the United States Constitution by accessing historical CSLI records containing the physical locations of cellphones without a search warrant.
