Due Process of Law Explained
No principle in American constitutional law is more fundamental than the guarantee that the government must follow fair procedures before depriving a person of life, liberty, or property. The Due Process Clause, appearing in both the Fifth and Fourteenth Amendments, is the Constitution’s most direct expression of the ideal of fundamental fairness. But due process means more than just fair procedures — it also protects certain substantive rights from government interference, regardless of the procedures used.
The Due Process Clause of the Fifth Amendment applies to the federal government, while the Due Process Clause of the Fourteenth Amendment applies to the states. Both provide that no person shall be “deprived of life, liberty, or property, without due process of law.” This seemingly simple command has generated an extraordinarily rich and complex body of constitutional law, touching nearly every aspect of the relationship between the individual and the state.
Procedural Due Process
Procedural due process requires the government to provide fair procedures when it deprives a person of life, liberty, or property. The precise procedures required depend on the nature of the interest at stake and the circumstances of the deprivation.
The Mathews Test
The Supreme Court established the modern framework for procedural due process claims in Mathews v. Eldridge (1976). Under Mathews, courts balance three factors: the private interest that will be affected by the government action, the risk of erroneous deprivation through the procedures used and the probable value of additional or substitute procedural safeguards, and the government’s interest, including the fiscal and administrative burdens that additional procedures would entail.
The Mathews test applies to a wide range of government actions, from welfare benefit terminations to parental rights proceedings to immigration hearings. The test is flexible, recognizing that the requirements of due process vary depending on the context. In some situations, due process may require a full evidentiary hearing before the deprivation occurs; in others, a post-deprivation hearing with notice and an opportunity to be heard may suffice.
What Constitutes Liberty or Property
Due process protections apply only when the government deprives a person of life, liberty, or property. The Court has given these terms broad construction. Liberty includes not only freedom from physical restraint but also the right to contract, to engage in common occupations, to marry, to establish a home, and to bring up children. Property includes not only real and personal property but also government benefits and entitlements that a person has a legitimate claim of entitlement to receive.
The distinction between a deprivation of liberty or property and a mere unilateral expectation has been important in many cases. In Board of Regents v. Roth (1972), the Court held that a nontenured college professor had no property interest in continued employment beyond the term of his contract, and therefore no right to a hearing before nonrenewal. In contrast, in Perry v. Sindermann (1972), the Court held that a professor with de facto tenure had a property interest that entitled him to procedural protections.
Notice and the Opportunity to Be Heard
The core requirements of procedural due process are notice and an opportunity to be heard. The notice must be reasonably calculated to apprise interested parties of the pendency of the action and afford them an opportunity to present their objections. The opportunity to be heard must be meaningful — it must occur at a meaningful time and in a meaningful manner.
The right to be heard includes the right to present evidence, to call witnesses, to cross-examine opposing witnesses, and to be represented by counsel. The extent of these rights varies depending on the context, but the fundamental requirement is that the affected person have an opportunity to present their case to a neutral decision-maker.
Substantive Due Process
Substantive due process protects certain fundamental rights from government interference, even when the government provides fair procedures. This branch of due process is among the most controversial areas of constitutional law, raising fundamental questions about the role of the judiciary in protecting unenumerated rights.
The Rise and Fall of Lochner
The modern debate over substantive due process begins with Lochner v. New York (1905), where the Court struck down a state law limiting bakers’ working hours as a violation of the liberty of contract protected by the Due Process Clause. The Lochner era, which lasted until the late 1930s, saw the Court invalidate numerous economic regulations as violations of substantive due process. The Court eventually repudiated Lochner in West Coast Hotel Co. v. Parrish (1937), holding that the Constitution does not protect the freedom of contract from reasonable economic regulation.
The demise of Lochner did not end substantive due process, but it shifted its focus from economic liberties to personal rights. The Court began to identify certain fundamental rights that are “implicit in the concept of ordered liberty” and protected from government interference.
Fundamental Rights Under Substantive Due Process
The Court has recognized several categories of fundamental rights protected by substantive due process. These include the right to marry (Obergefell v. Hodges, 2015), the right to procreate, the right to custody of one’s children, the right to direct the education and upbringing of one’s children, the right to bodily integrity, and the right to refuse medical treatment.
The most controversial substantive due process decision remains Roe v. Wade (1973), which held that the right to privacy encompasses a woman’s right to choose abortion. The Court overruled Roe in Dobbs v. Jackson Women’s Health Organization (2022), holding that the right to abortion is not a fundamental right protected by the Due Process Clause. The decision returned the abortion question to the political process, allowing states to regulate or prohibit abortion as their legislatures see fit.
The Subjectivity Criticism
Critics of substantive due process argue that it invites judges to impose their own policy preferences under the guise of constitutional interpretation. Justice Scalia was a prominent critic, arguing that the Due Process Clause is a guarantee of fair procedure, not a source of unenumerated substantive rights. Proponents respond that substantive due process is necessary to protect fundamental liberties that the framers could not have specifically enumerated and that the Constitution would be incomplete without it.
Due Process and the Incorporation Doctrine
The incorporation doctrine is itself rooted in the Due Process Clause. The Supreme Court has held that the Fourteenth Amendment’s Due Process Clause incorporates most of the protections of the Bill of Rights against the states, making them applicable to state and local governments. This process of selective incorporation has brought virtually all of the provisions of the Bill of Rights within the protection of the Due Process Clause.
The question of which rights are incorporated has been resolved through a case-by-case determination of whether a particular right is “fundamental to our scheme of ordered liberty.” The right to privacy, while not explicitly mentioned in the Constitution, has been recognized as a fundamental right protected by substantive due process.
Due Process and Civil Commitment
The Due Process Clause imposes important limits on the government’s power to confine individuals civilly. The Supreme Court has held that civil commitment requires proof by clear and convincing evidence that the individual is mentally ill and poses a danger to themselves or others. In Addington v. Texas (1979), the Court held that the clear and convincing evidence standard strikes the appropriate balance between the individual’s liberty interest and the state’s parens patriae interest in protecting those who cannot protect themselves.
The Court has also addressed the due process rights of individuals subject to civil commitment for sexual predator treatment. In Kansas v. Hendricks (1997), the Court upheld a state law providing for civil commitment of sexually violent predators, holding that the law served a legitimate non-punitive purpose and provided adequate procedural protections. The decision distinguished civil commitment from criminal punishment, emphasizing that the Due Process Clause does not prohibit preventive detention in all circumstances.
The procedural protections required in civil commitment proceedings under the Due Process Clause include the right to notice, the right to be present, the right to present evidence, and the right to counsel. Some states also provide additional protections, such as jury trials and periodic review of continued confinement, though these are not constitutionally required.
Due Process and the Incorporation Doctrine
What is the difference between procedural and substantive due process? Procedural due process concerns the fairness of government procedures — notice, hearing, and impartial decision-making. Substantive due process concerns the content of government actions — whether they interfere with fundamental rights regardless of the procedures used. Both are grounded in the same constitutional text but protect different interests.
Can due process rights be waived? Yes, due process rights can be waived, but the waiver must be knowing, intelligent, and voluntary. Courts scrutinize waivers of constitutional rights carefully, particularly in the criminal context. In civil contexts, parties may agree to alternative dispute resolution procedures, thereby waiving their right to a full judicial hearing.
What happens when the government violates due process? The remedy for a due process violation depends on the context. In criminal cases, violations may result in suppression of evidence, dismissal of charges, or reversal of a conviction. In civil cases, the remedy may be an injunction requiring the government to provide adequate procedures, an order reinstating a terminated benefit, or money damages under 42 U.S.C. § 1983.
Does due process require a trial in every case? No. Due process is flexible and requires only those procedures that are appropriate in light of the interests at stake and the circumstances of the case. Many government decisions, such as the denial of a driver’s license or the suspension of a student from school, may be made with less formal procedures than a full trial.
Conclusion
The Due Process Clause is one of the Constitution’s most important and versatile provisions. Its dual guarantees of procedural fairness and substantive protection of fundamental rights provide a crucial safeguard against government overreach. As the nation continues to debate the scope of constitutional liberty, the Due Process Clause will remain at the center of the most significant questions in American constitutional law.
