Due process and equal protection are both constitutional rights, but they answer different questions. Due process limits government’s power to take away life, liberty or property, and equal protection limits differences in treatment that government cannot justify.

Neither is reserved for citizens; the Fourteenth Amendment’s guarantees cover “any person.” Nor does a violation require a discriminatory law, because a fair-looking rule that officials enforce unequally can violate equal protection. What counts as a fair procedure depends on the setting: the Supreme Court has required a hearing before welfare benefits end but not before Social Security disability benefits do, where the recipient can respond first and is assured a hearing before the decision is final.

Two protections ask different questions

The Fifth Amendment forbids depriving any person of life, liberty or property without due process of law. The Fourteenth Amendment repeats that due process command for states and also prohibits denying any person within their jurisdiction equal protection of the laws.

When government cuts off a benefit, the due process question is whether the person had a protected claim to it and a fair chance to contest the loss. When government draws a line based on race, the equal protection question is what justifies the line.

The Fifth Amendment applies to federal action and has no equal protection clause; the Fourteenth, which has one, applies only to the states. Even so, in its May 17, 1954 decision in Bolling v. Sharpe, the Supreme Court ruled that segregated District of Columbia public schools violated Fifth Amendment due process. It reasoned that discrimination may be so unjustifiable that it violates due process.

So federal officials are also bound by constitutional equality requirements.

Government action can violate a neutral law’s promise

The Fourteenth Amendment reaches governmental action rather than merely private conduct, however wrongful that private conduct may be. Private discrimination can come within its reach when there is sufficient state involvement, a determination that depends on the facts and circumstances.

The key is governmental responsibility, not whether the unfair treatment arrived in a newly enacted law.

In Yick Wo v. Hopkins, decided May 10, 1886, the Supreme Court said discriminatory administration of a municipal laundry ordinance could violate the Constitution. It was admitted in the case that the petitioner and 200 of his countrymen were denied permission to keep operating their laundries, while all but one of the applications from people who were not Chinese were granted.

The Supreme Court explained that a rule fair on its face still violates equal protection when public authorities administer it to create unjust distinctions among people in similar circumstances.

The protections belong to persons, including noncitizens

Yick Wo explains that the Fourteenth Amendment protects all persons within the territorial jurisdiction of the United States, regardless of race, color or nationality. Due process and equal protection are therefore not only for American citizens, but not every immigration procedure gets the same constitutional treatment.

In Department of Homeland Security v. Thuraissigiam, the Supreme Court applied a long-standing rule: a noncitizen seeking initial admission to the United States is requesting a privilege and has no constitutional rights regarding the application. The Supreme Court rejected the argument that being apprehended 25 yards inside the country changed that initial-entry rule.

By contrast, in Landon v. Plasencia, the Supreme Court said a returning resident was entitled to due process in her exclusion hearing under the circumstances of that case. Here, the returning resident was a permanent U.S. resident coming back from a brief trip abroad, and the exclusion hearing was the procedure then used to decide whether she could enter the country. It remanded the case, sending it back to the appeals court to consider whether she had received due process. The entry rule cannot be turned into a blanket claim that everyone who lacks citizenship also lacks due process.

In Mathews v. Diaz, the Supreme Court explained that federal regulation of noncitizens’ entry and residence involves different equal protection considerations from a state’s treatment of noncitizens. State laws that draw distinctions based on citizenship status, called alienage classifications, generally receive strict scrutiny, the highest standard of review a court uses. But distinctions tied to certain self-government positions involving policymaking or authority over others need only satisfy rational basis review, a lower standard.

What a fair process requires

Before any process is owed, a person must have a protected interest in life, liberty or property at stake. Under Board of Regents v. Roth, a property interest in a benefit takes more than a desire for it or a one-sided expectation of it. A person must have a legitimate claim of entitlement, grounded in existing rules or understandings such as state law. Protected liberty includes freedom from physical restraint and can also include interests recognized by common law or statute.

Under Mullane v. Central Hanover Bank & Trust Co., notice must be reasonably calculated to tell interested parties that a proceeding is pending and give them a chance to object, with a reasonable time to appear.

To decide how much process is required, Mathews v. Eldridge looks to three factors: the private interest affected; the risk of a mistaken decision under the procedures used and the likely value of added safeguards; and the government’s interest, including the cost and administrative burden of more procedure.

An evidentiary hearing is an opportunity to present evidence to contest the decision. In Eldridge, the Supreme Court concluded that an evidentiary hearing was not required before Social Security disability benefits ended, given that the claimant could respond before any action and was assured a hearing and judicial review before the denial became final. For the welfare benefits at issue in Goldberg v. Kelly, the Supreme Court required a hearing before termination, with adequate notice and an effective opportunity to defend orally and confront adverse witnesses.

In rare emergencies, when quick action is needed to prevent imminent harm to the public and the private interest is reasonably judged less important, government may act with no notice and no opportunity to defend, subject to a later full hearing.

When property is lost because a government employee, without authorization, failed to follow procedures that are themselves adequate, due process may be satisfied by a court remedy that the person must start; a remedy for lost property does not necessarily provide adequate process for a loss of liberty. Mere official negligence causing unintended loss or injury does not itself implicate the Due Process Clause.

Some rights limit the result itself

Substantive due process protects fundamental personal rights against governmental interference, beyond the question of what procedure was followed. A hearing cannot, by itself, make a restriction on a protected fundamental right lawful.

The Fourteenth Amendment’s due process clause also makes many Bill of Rights protections apply to states, a doctrine called incorporation. Rights the Constitution does not list face a separate test. In Dobbs v. Jackson Women’s Health Organization, the Supreme Court said the clause guarantees some unenumerated rights, those not mentioned in the Constitution, but any such right must be deeply rooted in the nation’s history and tradition and implicit in the concept of ordered liberty. The 2022 Dobbs decision overruled Roe v. Wade and Planned Parenthood v. Casey and held that the Constitution does not protect a right to abortion.

The Dobbs majority expressly limited its decision to abortion and said it should not be understood to cast doubt on precedents that do not concern abortion. Other substantive due process precedents protect interracial marriage, parents’ direction of their children’s upbringing and same-sex marriage.

Different treatment requires a constitutional justification

Equal protection does not require identical treatment in every circumstance: the mere fact that a law classifies people, treating one group differently from another, does not make it invalid.

The standard a court applies depends on the kind of distinction, and it changes both how strong the justification must be and who carries the burden. A classification that burdens a fundamental right can trigger strict scrutiny.

Under Washington v. Davis, a government policy that is neutral on its face is not unconstitutional solely because it affects one race more than another; there must also be a racially discriminatory purpose. Discriminatory purpose can be inferred from the totality of relevant facts, including whether a law bears more heavily on one race than another.

Criminal justice shows enforceable protections and limits

Under In re Winship, due process requires proof beyond a reasonable doubt of every fact necessary to constitute the charged crime before conviction. Equal protection reaches a different part of the trial: jury selection.

Batson v. Kentucky prohibits prosecutors from excluding prospective jurors solely because of race or an assumption that jurors of that race cannot impartially consider the prosecution’s case. A Batson challenge has three steps. The defense makes an initial showing that prospective jurors were removed because of race; the prosecutor gives race-neutral reasons; and the defense gets a chance to show that those reasons are a pretext, with the trial court deciding whether they disguise discrimination.

In Flowers v. Mississippi on June 21, 2019, the Supreme Court held that the trial court committed clear error in concluding that the state’s removal of a Black prospective juror was not motivated in substantial part by discriminatory intent. It reversed the Mississippi Supreme Court’s judgment and remanded the case. On May 28, 2026, in Pitchford v. Cain, the Supreme Court reversed the U.S. Court of Appeals for the Fifth Circuit and remanded because the Mississippi trial court prevented defense counsel from pursuing the Batson argument at its third step.

These rulings show one way the Equal Protection Clause is enforced in criminal justice, and one measure of whether it has been effective: it can overturn a judgment when a court’s review of jury selection falls short. They do not show that racial discrimination has disappeared from the system, and sending a case back does not decide a defendant’s guilt.

Turning a broader disparity into proof about a particular decision can be a substantial obstacle. In McCleskey v. Kemp, a defendant relied on a statistical study to argue that Georgia’s capital punishment system violated the Equal Protection Clause. The Supreme Court said he had to prove that the decisionmakers in his own case acted with discriminatory purpose, and it found the study insufficient to establish that.

Turning a concern into a constitutional claim

Start by identifying the government actor, the interest taken away, the procedure used and any distinction the government made. For unequal treatment, separate evidence that results differed from evidence of the discriminatory purpose a court may require.

A federal civil rights law, 42 U.S.C. § 1983, allows a lawsuit against a person who, under color of state law, deprives someone of rights secured by the Constitution and federal laws. The phrase under color of state law covers action under a statute, ordinance, regulation or custom of a state, a territory or the District of Columbia; the statute does not name action by federal officials under federal law. Section 1983 is a route into court; it does not by itself prove a violation or decide what relief is available.

Qualified immunity can protect government officials from individual civil liability unless they violated a clearly established right that a reasonable official would have known about. Section 1983 also limits orders against judges: for acts taken in a judicial capacity, a court may not order a judge to act or stop acting unless a declaratory decree, a court’s formal statement of legal rights, was violated or declaratory relief was unavailable.
