The U.S. Constitution is the foundational legal document of the United States. It enumerates the powers that are held by the U.S. federal government and specifies that powers “not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people.” Thus, it serves as a barometer of which civil rights go to whom. Every piece of legislation in the United States must be justifiable under the Constitution, and legislation cannot conflict with any constitutional provision. The Constitution is composed of seven original articles and 27 amendments, with the first ten being known as the Bill of Rights. These amendments limit the power of government and safeguard individual liberty. Remarkably, the U.S. Constitution is the shortest written constitution that holds sway anywhere in the world. Despite this, however, it is notoriously challenging to interpret and implement. It is important for the average citizen to strive to understand the amendments and how they influence the rights of the individual, and the Fourth Amendment is arguably one of the most important.
What Does the Fourth Amendment Mean?
The Fourth Amendment reads as follows: “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 warrants 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.” Generally, this is understood as providing protection against “unreasonable” search and seizure by the government. To determine whether an instance is “reasonable,” authorities must balance the intrusion on an individual’s constitutional rights with what are called “legitimate government interests,” including safeguarding the public. In most cases, authorities must seek a warrant before executing search and seizure, but in some rare instances, such as chasing someone from the scene of a crime, they can explain their “probable cause” to a judge after taking action.

Important Fourth Amendment Cases
Judges use legal precedent to help them determine how to rule in any particular case, and this is just as true in constitutional law as it is in other areas. Many of the most important cases related to the Fourth Amendment are those that specify the situations under which a search is likely to be reasonable. Different rules apply to the home, private vehicles, schools, and one’s person. In fact, Fourth Amendment protections vary significantly based on where, and sometimes who, you are. For example, Payton v. New York, 445 U.S. 573 (1980) established that search and seizure conducted inside a home without a warrant is “presumptively unreasonable.” However, according to New Jersey v. TLO, 469 U.S. 325 (1985), school officials do not need a warrant to search their students. In some places, such as border crossings, all persons are subject to search.
