Due process places constitutional limits on government actions affecting life, liberty, or property.

Due process is one of the basic protections built into the U.S. Constitution. In simple terms, it means the government must follow lawful and fair procedures before it can deprive a person of life, liberty, or property.


The principle appears in both the Fifth and Fourteenth Amendments. The Fifth Amendment restricts the federal government, while the Fourteenth Amendment says that states may not deprive "any person" of life, liberty, or property without due process of law.


Where did due process come from?


The idea behind due process is much older than the United States.


Its roots are often traced to Magna Carta, issued in England in 1215. One of its lasting principles was that government could not imprison or punish a free person except according to lawful judgment and the "law of the land." The National Archives describes the Fifth Amendment's Due Process Clause as a direct descendant of this principle.


When the Bill of Rights was ratified in 1791, the Fifth Amendment established due process as a constitutional restriction on the federal government. Its language protects a "person," rather than only a citizen, from being deprived of life, liberty, or property without due process of law.

The concept behind due process has deep historical roots, including the Magna Carta's law-of-the-land principle.

How did the Fourteenth Amendment expand due process?


Originally, the Bill of Rights restricted the federal government rather than state governments. That constitutional landscape changed after the Civil War.


Ratified in 1868, the Fourteenth Amendment included its own Due Process Clause, specifically limiting state governments. Over time, the Supreme Court used the Fourteenth Amendment to apply most protections in the Bill of Rights to the states through a process known as incorporation.


As a result, many constitutional protections now limit government action at federal, state, and local levels.

Procedural due process can require safeguards such as notice and a meaningful opportunity to be heard, depending on the circumstances.

What does due process look like in practice?


One major part of due process is procedural due process. This concerns how government decisions are made.


When the government seeks to take away a protected liberty or property interest, due process can require safeguards such as notice and a meaningful opportunity to be heard. Exactly what procedures are required depends on the circumstances.


Due process is therefore not limited to criminal trials. It can also matter in civil and administrative proceedings when government action affects legally protected interests.


Courts also recognize substantive due process, a doctrine concerning whether certain government actions affecting protected liberties are constitutionally permissible regardless of the procedures used. The scope and application of that doctrine have been the subject of extensive legal and political debate.

The Fifth and Fourteenth Amendment Due Process Clauses use the term "person," making due process a protection that is not textually limited only to U.S. citizens.

Why does due process protect everyone?


The importance of due process becomes clearer when considering what could happen without it. Government officials could potentially impose serious consequences without giving affected people a meaningful opportunity to challenge the decision.


Due process places constitutional limits on that power. It requires government to operate within legal rules rather than relying solely on the discretion of individual officials.


Importantly, the Fifth and Fourteenth Amendments use the term "person" in their Due Process Clauses. The constitutional text therefore does not limit this protection simply to U.S. citizens, although the precise protections available can depend on the legal context.


Due process does not guarantee that every person will receive the outcome they want. Instead, it establishes a constitutional requirement that government respect applicable legal protections when taking actions that affect life, liberty, or property.


That principle is why due process remains fundamental to the American legal system. It helps ensure that government power is exercised through law and that people have protections when that power directly affects their lives.
