Procedural due process is the branch of due process doctrine concerned with how the state acts, rather than what it does. It demands that before a government deprives an individual of a protected interest in life, liberty, or property, it must provide fair procedures—typically including adequate notice, a meaningful opportunity to be heard, and a neutral decision-maker.
In United States constitutional law, the requirement is rooted in the Fifth Amendment (binding the federal government) and the Fourteenth Amendment (binding the states), both of which forbid deprivation "without due process of law." The U.S. Supreme Court's decision in Mathews v. Eldridge, 424 U.S. 319 (1976), established the dominant balancing test: courts weigh (1) the private interest affected, (2) the risk of erroneous deprivation under existing procedures and the probable value of additional safeguards, and (3) the government's interest, including administrative burden. Earlier, Goldberg v. Kelly, 397 U.S. 254 (1970), held that welfare recipients must receive an evidentiary hearing before benefits are terminated.
What process is "due" varies with context. A criminal defendant facing imprisonment is entitled to robust trial rights; a public employee facing dismissal or a student facing school suspension may be entitled to more limited procedures. The doctrine also requires a recognized "liberty" or "property" interest, which the Court has held arises from statutes, contracts, or established practices rather than mere expectations (Board of Regents v. Roth, 408 U.S. 564 (1972)).
Analogous principles appear in international human rights instruments. Article 14 of the International Covenant on Civil and Political Rights (1966) guarantees a fair and public hearing by a competent, independent, and impartial tribunal, and Article 6 of the European Convention on Human Rights (1950) sets out the right to a fair trial. While terminology differs—"natural justice" in Commonwealth systems, droits de la défense in French law—the core idea of procedural fairness is widely shared across legal traditions.
Example
In *Goldberg v. Kelly* (1970), the U.S. Supreme Court ruled that New York City could not terminate welfare benefits without first giving recipients an evidentiary hearing, applying procedural due process under the Fourteenth Amendment.
Frequently asked questions
Procedural due process concerns the fairness of the procedures used to deprive someone of a protected interest, while substantive due process limits what the government may do regardless of procedure, protecting certain fundamental rights from infringement.
