What Is Due Process?
The constitutional guarantee that the government cannot deprive you of life, liberty, or property without fair procedures and, in some cases, for substantive reasons. It is the legal requirement that the government play fair.
Quick Answer
The constitutional guarantee that the government cannot deprive you of life, liberty, or property without fair procedures and, in some cases, for substantive reasons. It is the legal requirement that the government play fair.
Full Explanation
Due process is guaranteed by the Fifth Amendment (applying to the federal government) and the Fourteenth Amendment (applying to state governments). Both say the government cannot deprive a person of 'life, liberty, or property, without due process of law.'
Courts have interpreted this to mean two things. Procedural due process requires the government to follow fair procedures before taking away something of value. The classic formula from Mathews v. Eldridge (1976) balances three factors: the private interest at stake, the risk of error under current procedures and the value of additional safeguards, and the government's interest (including the burden of additional procedures). At minimum, procedural due process generally requires notice and an opportunity to be heard.
Substantive due process is a broader and more controversial doctrine. It holds that certain fundamental rights are so important that the government cannot infringe on them at all — not even with perfect procedures. The Supreme Court has used substantive due process to protect rights not explicitly listed in the Constitution, including the right to privacy, contraception, marriage (including same-sex marriage), and decisions about child-rearing. Obergefell v. Hodges (2015) and many other landmark cases rest on substantive due process.
The level of scrutiny courts apply depends on what right is at stake. Fundamental rights and suspect classifications get strict scrutiny; other regulations get rational basis review.
Real-World Example
If the government wants to fire a tenured public school teacher, it must provide the teacher with notice of the charges and an opportunity to respond before termination. Simply firing the teacher without explanation violates procedural due process because the teacher has a protected property interest in continued employment.
In Mathews v. Eldridge (1976), the Supreme Court addressed whether Social Security disability recipients were entitled to a hearing before their benefits were cut off. The Court said written submissions without an oral hearing were sufficient, weighing the government's interest in efficiency against the recipient's interest in continued benefits.
Why It Matters for Law Students
Due process is one of the most important concepts in constitutional law, criminal procedure, and administrative law. It sets the floor for fair government action in virtually every context — criminal trials, civil hearings, school discipline, benefit termination, and more. The procedural/substantive distinction and the levels of scrutiny are tested constantly on the bar exam.
