What Is Due Process? The 5th and 14th Amendments and the Rights They Protect

It has been used to protect rights ranging from fair trials to abortion — and the Supreme Court's 2022 Dobbs decision showed that substantive due process rights can disappear as well as be created.
- Due process is guaranteed by the 5th and 14th Amendments — requiring fair legal procedures (procedural due process) and protecting fundamental rights (substantive due process).
- Substantive due process is the constitutional basis for rights not explicitly mentioned in the text — including privacy, contraception, same-sex marriage, and (formerly) abortion rights.
- Dobbs v. Jackson (2022) overruled Roe v. Wade by rejecting substantive due process protection for abortion — raising questions about other rights recognized under the same doctrine.
- Procedural due process protections have been invoked in Trump immigration enforcement cases — courts ruling that certain deportation processes violated due process requirements.
Procedural vs. Substantive Due Process
| Type | Question It Answers | Examples |
|---|---|---|
| Procedural Due Process | Did the government follow fair procedures before depriving someone of life, liberty, or property? | Right to notice of charges, right to a hearing, right to present evidence before license revocation or property seizure |
| Substantive Due Process | Does the government have the right to take this action at all, regardless of procedure? | Right to marry, right to contraception, right to same-sex intimacy, formerly: right to abortion |
| Incorporation Doctrine | Which Bill of Rights provisions apply to states via 14th Amendment due process? | Nearly all Bill of Rights protections now incorporated against states through selective incorporation |
2025-26: Due Process in an Era of Aggressive Executive Action
The Trump administration's use of the Alien Enemies Act of 1798 to deport Venezuelans without individual immigration hearings triggered immediate due process challenges. Federal courts in 2025 halted some deportations, ruling that individuals must have an opportunity to contest their removal. The Supreme Court's role in defining how much process is due for non-citizens is central to the 2025-26 immigration fights.
With Roe and Casey overturned in Dobbs (2022), abortion polling now depends entirely on state law. As of 2026, 14 states have near-total bans and another 6 have significant restrictions. The political battle has shifted to state ballot measures — abortion rights measures won in 7 of 10 states that voted on them in 2022-24. Congress has not passed either a federal ban or a federal protection.
DOGE's rapid elimination of federal contracts, grants, and agency functions in 2025 generated procedural due process litigation from affected contractors and employees. Courts have to determine whether grants, contracts, and government employment constitute protected "property" or "liberty" interests requiring pre-deprivation notice and hearing. Several preliminary injunctions were issued in early 2025 on exactly these grounds.
Frequently Asked Questions
What process is due before the government fires a public employee?
For government employees with a property interest in their job — typically those who can only be fired "for cause" under statute or contract — the Supreme Court held in Cleveland Board of Education v. Loudermill (1985) that the government must at minimum provide oral or written notice of the charges, an explanation of the evidence, and an opportunity for the employee to respond before termination. A full post-termination hearing may satisfy more elaborate process requirements. Trump administration mass firings in 2025 triggered Loudermill-based litigation.
What rights does substantive due process still protect after Dobbs?
The Dobbs majority specifically stated it was not disturbing Griswold (contraception), Lawrence (same-sex intimacy), or Obergefell (same-sex marriage). But Justice Thomas's concurrence called for reconsidering all three. Congress passed the Respect for Marriage Act in 2022 to protect same-sex and interracial marriage in federal law. The substantive due process doctrine itself remains valid law — Dobbs did not eliminate it, it held only that abortion was not a right "deeply rooted in this Nation's history and tradition."
Does due process apply to non-citizens?
Yes. The Supreme Court has consistently held that the Due Process Clause of the 14th Amendment protects "persons," not just citizens. Undocumented immigrants and non-citizens physically present in the United States are entitled to due process protections. However, the scope of required process for immigration proceedings is different from criminal proceedings — Congress has significant constitutional latitude to set immigration procedures, and courts have allowed expedited removal without full hearings in many circumstances.
