State lawmakers are moving again on a question that should not be complicated: when a case is heard in an American courtroom, what law governs?
The answer is supposed to be simple. The U.S. Constitution is supreme. State constitutions and duly enacted statutes come next. Judges may consider contracts, arbitration agreements, and in some cases foreign law principles where American law allows it. But none of that can override basic constitutional rights.
That last part is where the fight begins. And it is why legislation often described as American Laws for American Courts keeps returning in statehouses.
What these bills are trying to do
The core idea is narrow. A state court should not enforce any foreign law, legal code, or private agreement if doing so would violate rights protected by the U.S. Constitution or the state constitution.
That means due process. Equal protection. Free exercise. Free speech. Property rights. Parental rights where recognized under state law. The ordinary guarantees that are supposed to follow an American citizen into an American courtroom.
In practice, supporters say the bills are aimed less at day-to-day judicial chaos than at edge cases most voters never see until the damage is done. Family law disputes. International custody fights. Foreign forum-selection clauses. Arbitration provisions in contracts. Probate and estate matters involving overseas legal systems. Immigration-adjacent civil disputes. The kinds of cases where a judge may be asked to recognize a foreign judgment or defer to a legal framework that does not treat men and women equally, does not honor religious liberty as Americans understand it, or does not give the same procedural fairness required here.
That is not theoretical. American courts already deal with questions involving foreign judgments and choice-of-law provisions. Usually, the system handles them through existing conflict-of-laws rules and public policy exceptions. Usually.
Usually is doing a lot of work there.
Why states say existing law is not enough
Opponents often argue that courts already have tools to reject foreign law when it violates public policy. That is true, as far as it goes. Judges are not helpless. They can and do refuse enforcement in some circumstances.
But supporters of these bills make a different point. If constitutional supremacy is the rule, why leave it to implication? Why rely on scattered case law, judicial discretion, or the willingness of a litigant to spend years and tens of thousands of dollars appealing a bad ruling?
Legislatures write rules precisely so citizens do not have to guess.
This is a familiar problem in conservative legal politics. The establishment answer is often that the guardrails already exist somewhere in the casebooks. Then an ordinary family discovers those guardrails are expensive, slow, and unevenly applied. That is not much comfort if you are the one in court.
A statute can do what a press release cannot. It can tell a trial judge, in plain English, that no foreign legal principle is enforceable in that courtroom if it would deny a constitutional right.
That is clarity. And clarity matters.
The constitutional argument
The legal foundation here is not exotic. The Supremacy Clause governs federal constitutional authority. State judges are bound by the U.S. Constitution. State constitutions provide additional protections in many jurisdictions. American courts have long recognized limits on enforcing foreign judgments or agreements that offend public policy.
So the conservative case is not that foreign law is secretly taking over the republic. The conservative case is that sovereignty requires clean lines. A nation confident in its own legal order does not blur those lines for the sake of fashionable internationalism or elite discomfort with asserting American constitutional norms.
Courts can recognize facts arising abroad. They can interpret contracts with international components. They can respect lawful arbitration. But they cannot treat constitutional guarantees as optional terms and conditions.
They should not have to be reminded. Yet here we are.
The criticism these bills face
Critics usually raise three objections.
First, they say the bills are unnecessary because existing doctrine already protects litigants. As noted, that argument depends on trusting every court to get every hard case right without clear statutory direction. Voters have heard versions of that promise before.
Second, they say the legislation can be drafted too broadly and create confusion in ordinary business disputes involving foreign contracts. That is a fair drafting concern. A sloppy bill can invite litigation. Legislatures should define terms carefully and make clear that the target is not all foreign law, but only any application that would violate constitutional or statutory rights.
Third, some critics argue the bills are really aimed at one religion and risk becoming a symbolic culture-war device. Legislatures should avoid that trap. The cleanest version of the policy does not name a religion, a country, or a legal tradition. It states a neutral rule: no foreign law or tribunal outcome may be enforced in a way that strips an American of rights guaranteed under state or federal law.
That is not bias. That is self-government.
Why this matters beyond the courtroom
This issue lands because it touches a broader conservative concern that runs through immigration, education, and administrative law. Who decides? By what authority? Under what rules? And can the citizen see the line of accountability?
If the answer in a legal proceeding becomes murky, public confidence drops fast. The average citizen may not know the details of conflict-of-laws doctrine. He does know whether the system sounds like it belongs to him.
That is the larger policy implication. When institutions hesitate to say plainly that constitutional rights come first, they invite distrust they later pretend to find irrational.
And there is another point. A legal system that will not clearly defend its own first principles becomes easier to bend in other areas. If judges and lawmakers grow comfortable treating foundational rights as negotiable in one corner of the law, that habit does not stay contained there. It spreads.
You can see the same instinct in agency rulemaking, in campus speech codes, in compelled pronoun fights, in selective religious-liberty exceptions, and in local zoning games that somehow always burden the politically weak. The details differ. The habit is the same. Rights for some people become balancing tests. For others, they remain rights.
The better way to write these laws
If states are going to act, they should do it carefully.
Use religion-neutral language.
Limit the statute to cases where applying foreign law would violate a right guaranteed by the U.S. Constitution, the state constitution, or state statute.
Make clear that lawful international commerce and ordinary contract interpretation can continue unless constitutional protections are impaired.
Preserve judicial discretion to recognize foreign judgments that do not conflict with public policy.
Provide a clear cause of action or defense so citizens can raise the issue early, before years of litigation pile up.
That is how you turn a talking point into an enforceable rule.
A simple standard
The standard should be easy enough for any voter to understand. In an American court, the Constitution wins. Not sometimes. Not after an expensive appeal. Not unless a judge decides the violation is minor. It wins.
That is the whole point of constitutional government. Rights do not depend on geography, fashion, or whether a well-connected lawyer can dress up a foreign legal principle in respectable language.
State legislatures moving on this issue are responding to a real concern, even when the immediate case count is small. The number matters less than the principle. You do not wait for a larger breach before locking a door you know should have been shut.
Conservatives should insist on precision, not panic. But they should also insist on saying the obvious out loud. The courtrooms funded by American taxpayers exist to apply American law under the American constitutional order.
If a state bill does that cleanly, pass it. If it does not, fix it and pass it anyway. Because the longer institutions act embarrassed by constitutional supremacy, the more voters will suspect those institutions no longer believe in it.
