Search and seizure
In 1946, the Supreme Court of New Zealand heard a case that would define privacy rights for decades. The court ruled that everyone has the right to be secure against unreasonable search or seizure, whether of the person, property, or correspondence. This principle appears in Article 14 of Italy's Constitution and Section 21 of the New Zealand Bill of Rights Act 1990. Yet these protections vary wildly across nations. In some countries, constitutional guarantees exist on paper but are routinely ignored by state authorities. Courts have begun distinguishing between what is lawful versus what is reasonable, creating a gap where legal searches can still feel intrusive. The result leaves individuals with few remedies when evidence is seized without yielding any proof of wrongdoing.
A police officer in Wentworth, New South Wales, searched the vehicle of a suspected drug smuggler near the Victorian border in 1997. That operation, called Reciprocity, involved DEA investigators finding $5.6 million hidden in a ceiling compartment of a truck. Across the United Kingdom, stop-and-search powers differ depending on jurisdiction. English common law once used writs like arrestandis bonis ne dissipentur to seize goods likely to be mishandled during ownership disputes. Another writ, attachiamenta bonorum, allowed seizure of personal property to recover debts. Modern policing now allows officers to search people and places without making an arrest first. These procedures operate under different rules in England and Wales compared to Scotland, reflecting centuries of evolving legal traditions.
The text of the Fourth Amendment states that people shall be secure against unreasonable searches and seizures. In United States v. Jacobsen, the Supreme Court summarized this brief language into clear definitions of what constitutes a search or seizure. By 2012, justices clarified that the reasonable expectation of privacy test had been added to but not substituted for the common-law trespassory test. Property rights establish a baseline level of protection under this amendment. Courts have found that individuals do not possess a reasonable expectation of privacy in information transferred to third parties, such as writing on the outside of an envelope sent through mail. Garbage left outside the curtilage of a home also falls outside protected expectations, even if contents inside remain private.
Police may follow a suspect into a residence during hot pursuit of a fleeing felon if probable cause exists. This exigent circumstances exception requires officers to act quickly because evidence is in imminent danger of being removed or destroyed. Another scenario involves continuing danger where officers believe people needing assistance are present. The word automobile does not serve as a talisman making the Fourth Amendment disappear, according to Coolidge v. New Hampshire. Lowered expectations of privacy apply inside motor vehicles, yet warrants remain necessary unless specific exceptions arise. Consent from property owners can override warrant requirements if given voluntarily, though no clear test determines voluntariness beyond total circumstances assessment.
Evidence obtained through illegal searches cannot be used against defendants at trial under the exclusionary rule. Some narrow exceptions exist when police acted in good faith pursuant to a warrant they believed valid at the time. Courts analyze four doctrines: reasonableness, probable cause, judicial authority, and particularity. Only searches meeting all minimal measured requirements stand unchallenged in court. Probable cause demands an acceptable degree of justified suspicion before any search occurs. Particularity requirements appear directly in constitutional text and are scrutinized prior to warrant issuance by officiating judges or magistrates. State constitutions may provide additional protections beyond federal standards even if deemed reasonable under U.S. law.
In Federal Trade Commission v. American Tobacco Co., Justice Holmes ruled that general fishing expeditions into private papers violated the spirit and letter of the Fourth Amendment. The 1946 case Oklahoma Press Pub. Co. v. Walling distinguished between figurative constructive searches and actual seizure requiring warrants based on probable cause. Constructive searches involving corporate records do not apply the full Fourth Amendment since corporations lack certain individual rights. Supreme Court interpretation has evolved toward stronger government investigatory power regarding administrative subpoenas. This shift allows broader access to corporate documents while maintaining some limits on what constitutes unreasonable intrusion into business operations.
