Every few years, an old American argument returns with a new headline: What if a state just refuses to go along with the Supreme Court? In recent weeks, that question flared up again after reports that a Hawaii state judge, speaking publicly, suggested the state should “defy” the Court.
It is a tempting idea if you are furious at a ruling. It is also the kind of idea that sounds more plausible than it is, largely because the Constitution never uses the phrase “judicial supremacy.”
But the Constitution does build a system in which federal law prevails over state law, federal courts decide federal questions, and Supreme Court judgments bind the parties before the Court. That is the core reality behind the more familiar slogan: states do not get to veto the Supreme Court.

What people mean by judicial supremacy
“Judicial supremacy” is shorthand for a practical rule of American government: when the Supreme Court decides a federal question in a case and announces a controlling rule, lower courts are expected to follow that rule in later cases, and officials cannot treat the Court’s judgments as optional.
Two clarifications matter.
- The Supreme Court is not supreme over politics. People can criticize it. Elected officials can campaign against its reasoning. Congress can change statutes when the issue is statutory, not constitutional.
- The Supreme Court is supreme in the courtroom. Its judgments are final within the judicial branch. Lower courts follow its precedents under the doctrine of vertical stare decisis, and parties subject to an order must comply unless the order is stayed or later reversed.
The Constitution does not say, “the Supreme Court gets the last word.” Instead, the last word emerges from how Article III, the Supremacy Clause, and long-settled judicial practice fit together.
The Supremacy Clause
Start with the constitutional text states cannot evade: Article VI, the Supremacy Clause.
It says the Constitution, federal laws made pursuant to it, and treaties are “the supreme Law of the Land,” binding judges in every state, even when state constitutions or statutes point the other direction.
Notice what that does and does not do.
- It does: make valid federal law superior to conflicting state law. States cannot “nullify” federal law by declaring it void inside their borders.
- It does not: spell out every detail of who decides every federal dispute. The federal judiciary’s authority to decide cases comes from Article III and statutes Congress has enacted to implement it.
So when someone says “a state will defy the Supreme Court,” the immediate constitutional problem is that states are bound by federal law, and the Supreme Court is the court of last resort when it has jurisdiction over a federal question.
Article III and judicial review
Article III creates “one supreme Court” and authorizes Congress to establish lower federal courts. It grants the federal judiciary power over categories of cases, including those arising under the Constitution and federal laws.
The Constitution never explicitly says “courts may strike down unconstitutional laws.” But the logic of judicial review was articulated early and has become foundational: deciding a case often requires deciding which law controls, and unconstitutional laws cannot control.
That is the core of Marbury v. Madison (1803), which did not invent judicial review out of thin air so much as formalize what a written constitution implies. If the Constitution is higher law, courts must apply it when lower laws conflict.
Once that is true, the next step is structural. The Supreme Court’s interpretations bind lower courts in later federal-question cases, not because the Constitution contains a “supremacy” slogan, but because a judicial hierarchy cannot function if every court is free to treat the top court as advisory.
Can a state ignore a decision?
It depends what “ignore” means, because not every Supreme Court opinion binds every state official in the same way.
1) A Supreme Court judgment binds the parties
If the Court issues an order against a state official or state agency, that order must be followed unless it is stayed (paused) or later reversed. Disobeying a court order is not a political disagreement. It can lead to contempt sanctions.
2) A Supreme Court precedent binds lower courts
State courts, when deciding federal questions, must follow Supreme Court precedent. Federal district courts and federal circuit courts must as well. A state judge who says “we will not follow the Supreme Court” is not describing a lawful option. They are describing a refusal to apply controlling law. The Court made this point bluntly in Cooper v. Aaron (1958), rejecting the idea that states may disregard the Court’s constitutional rulings.
3) An opinion does not rewrite state law overnight
When the Court announces a constitutional rule, states often have to change laws, policies, and procedures to avoid future violations. That process can be slow, messy, and full of good-faith confusion. But implementation friction is different from open defiance.
If a state refuses
The Constitution does not send a magical enforcement squad the moment a governor or judge announces resistance. Enforcement is legal, procedural, and sometimes painfully incremental. But it is real.
Injunctions and enforcement
Most modern compliance fights play out through injunctions, court orders telling officials to do something or stop doing something. If an official refuses, the federal court can impose escalating consequences.
- Contempt of court: A judge can hold officials in civil contempt, imposing fines until compliance occurs. In extreme cases, courts can order coercive detention, though that is rare and politically explosive.
- Attorney’s fees and damages: In many civil-rights contexts, prevailing plaintiffs can recover attorney’s fees under statutes such as 42 U.S.C. § 1988. Separate damages actions may be available depending on the claim and immunity doctrines.
- Structural remedies: Courts can require reporting, monitoring, or specific operational changes when a constitutional violation is ongoing and systemic.
Federal versus state courts
If a state court refuses to follow Supreme Court precedent on a federal issue, litigants can seek review, and the Supreme Court can reverse. If the issue is a state official’s ongoing conduct, plaintiffs can often file directly in federal court seeking prospective relief against the responsible officials.
The role of the executive branch
In the hardest cases, enforcement can implicate executive power. The Justice Department can bring suits to enforce federal rights and can intervene in major compliance disputes. Historically, federal troops and federal marshals have been used in extreme confrontations, but those are the outliers that prove the rule: defiance is not a “state option,” it is a constitutional crisis.
States’ rights and disagreement
States have real constitutional powers. They run elections, license professions, operate courts, and police most criminal law. They also retain broad authority under the Tenth Amendment, which reserves powers not delegated to the federal government.
But “states’ rights” is not a right to ignore federal law. The federal system is built on dual sovereignty, not state supremacy. When federal law is valid and on point, it displaces contrary state law.
One important nuance is often confused with “defying” the Court: the anti-commandeering doctrine. Under cases such as Printz v. United States (1997) and Murphy v. NCAA (2018), the federal government generally cannot force states to use state officials or state legislatures to administer or enforce a federal regulatory program. That is not nullification. It is a limit on how the federal government may implement federal law. Federal law can still be enforced by federal actors, and state officials still must comply with binding federal court orders directed at them.
There are lawful forms of resistance and disagreement, and they matter because they are how our system stays democratic instead of merely hierarchical:
- Legislative revision: If the Supreme Court interpreted a statute, Congress can often amend the statute.
- New litigation: States can bring new cases that test the boundaries of a precedent or ask the Court to reconsider it.
- Constitutional amendment: If the issue is truly constitutional and the Court’s interpretation is widely rejected, Article V provides a path, intentionally difficult, to change the text.
What states cannot do is declare, unilaterally, that Supreme Court decisions are optional.
Nullification and resistance
The United States has seen versions of this conflict before, and the pattern is consistent.
- Nullification theory: The idea that states can nullify federal law was argued in the early republic and resurfaced repeatedly. It never became accepted constitutional doctrine.
- Desegregation resistance: After Brown v. Board of Education (1954), some state officials attempted “massive resistance.” In Little Rock, federal authority ultimately backed enforcement. The long delay in compliance is a reminder that legal supremacy is not the same as instant social change, but the constitutional outcome was not in doubt.
When a state “defies” the Court, what follows is not a new, parallel constitutional order. What follows is litigation, injunctions, sanctions, and mounting institutional pressure until compliance occurs or higher authorities step in.
So can Hawaii defy the Court?
Not lawfully, not if we mean defy in the literal sense: refusing to follow binding federal judgments or instructing state courts to ignore controlling Supreme Court precedent on federal questions.
If a Hawaii court or official actually tried to treat a Supreme Court federal-question ruling as nonbinding, the pathway would be familiar. The losing party would seek review through the normal appellate process, and if there is an ongoing federal-rights violation, plaintiffs could sue responsible state officials in federal court for prospective relief. The fight would not be resolved by speeches. It would be resolved by orders.
States can disagree. They can criticize the Court. They can pursue lawful avenues to narrow, distinguish, or overturn precedents through new cases. They can lobby Congress and the public. They can even gamble that enforcement will be slow.
But the Constitution’s architecture is clear: under Article VI, federal law is supreme. Under Article III, federal courts decide federal cases. And in a system with one Supreme Court, final has to mean something.
FAQ
Is the Supreme Court above the Constitution?
No. The Court is bound by the Constitution, but it is the highest court empowered to interpret it in cases properly before it. That difference is why Americans debate the Court’s reasoning while still accepting that its judgments are binding.
Can a state judge refuse to apply Supreme Court precedent?
Not on a federal question. State judges are bound by the Supremacy Clause to apply federal law as interpreted by the Supreme Court. A refusal can be corrected on appeal and can trigger federal litigation depending on the context.
What if a state legislature passes a law contradicting a ruling?
The law can be challenged and enjoined. Passing the law may be politically expressive, but if it conflicts with controlling constitutional doctrine, courts can block its enforcement against affected parties.
What happens if a governor refuses to comply with an order?
The federal court can hold responsible officials in contempt, impose fines, and issue additional enforcement orders. In extreme scenarios, enforcement can escalate through federal executive action, but most disputes are resolved through the courts and political pressure long before that.
Does supremacy mean states must enforce federal law?
No. Under the anti-commandeering doctrine, states generally cannot be required to use state officials to administer federal programs. But states still cannot block federal enforcement, and state officials still must comply with binding federal court orders directed at them.
