due process of law
n. a fundamental principle of fairness in all legal matters, both civil and criminal, especially in the courts. All legal procedures set by statute and court practice, including notice of rights, must be followed for each individual so that no prejudicial or unequal treatment will result. While somewhat indefinite, the term can be gauged by its aim to safeguard both private and public rights against unfairness. The universal guarantee of due process is in the Fifth Amendment to the U.S. Constitution, which provides "No person shall…be deprived of life, liberty, or property, without due process of law," and is applied to all states by the 14th Amendment. From this basic principle flows many legal decisions determining both procedural and substantive rights.
