Due process is a requirement that legal matters be resolved according to established rules and principles, and that individuals be treated fairly. Due process applies to both civil and criminal matters.

In countries with developed legal systems, individuals expect that the rights enshrined in their constitutions will be applied to them fairly. This expectation—of due process—outlines the relationship individuals expect to have with their local, state, and federal governments; specifically, that the rights of the individual will not be violated.

History of Due Process

The origin of due process is often traced back to the Magna Carta, a 13th-century document that outlined the relationship between the English monarchy, the Church, and feudal barons. The document referred to as a charter (“Carta” means charter in medieval Latin), sought to address many economic and political grievances that barons had with the monarchy. In one of its clauses, the king promised that “No free man shall be seized or imprisoned, or stripped of his rights or possessions, or outlawed or exiled, or deprived of his standing in any other way, nor will we proceed with force against him, or send others to do so, except by the lawful judgment of his equals or by the law of the land.” The king was thus prevented from arbitrarily changing or ignoring laws, with the Magna Carta establishing the rule of law that the monarchy must follow.

The due process continued to be a part of British law for centuries after the signing of the Magna Carta, but the relationship between parliament and the courts limited its application in practice. The courts did not have the power of judicial review, which would have allowed them to determine whether government actions violated the rule of law, and thus could not always enforce due process. Judges could not be as assertive in defending due process in the face of parliamentary action, with the opposite holding true in the United States.

Due Process in the United States

In the United States, due process is outlined in both the Fifth and Fourteenth Amendments to the Constitution. Each Amendment contains a Due Process Clause, which prohibits the government from taking any action that would deprive a person of, “Life, liberty or property without due process of law." The Due Process Clause provides several types of protection: procedural due process, substantive due process, protection from vaguely written laws, and the incorporation of the Bill of Rights. Courts have taken an assertive approach to uphold due process, which has resulted in the executive and legislative branches of government adjusting how laws and statutes are written. Laws that are explicitly written not to violate the Flimdue process are those that are least likely to be struck down by the courts.

An example of due process is the use of the eminent domain. In the United States, the Takings Clause of the Fifth Amendment prevents the federal government from seizing private property without notice and compensation. While the use of an eminent domain is granted to the federal government, if it wants to use a parcel of land to build a new highway it will have to (typically) pay fair market value for the property. The Fifteenth Amendment extends the Takings Clause to state and local governments.
