The Problem Gets a Name
Several state legislatures are taking concrete action to prevent foreign legal systems from influencing their courts. They are doing this because it is happening. Judges cite international law, foreign court decisions, and treaty obligations in ways that bypass the legislative process entirely. No vote. No public debate. Just a citation.
This is not a distant threat. It happens regularly enough that legislatures are writing it down and making it explicit: American courts answer to American law, made by American voters through their representatives.
What the Legislation Actually Says
The approach varies by state, but the principle is consistent. Some legislatures are amending statutes to prohibit judges from citing foreign legal systems as binding authority in interpreting state law. Others are clarifying that international treaties do not override state constitutional provisions without explicit legislative action. A few are going further, establishing that state sovereignty includes the power to reject any foreign legal principle applied within state borders.
The mechanism matters. These are not gestures. They are legislative statements with teeth—directing judges where they can and cannot look when interpreting the law.
Why This Matters in Practice
Consider what happens now. A judge faces a constitutional question about privacy rights, religious exercise, or property. The judge looks to the Constitution. The judge also might look to decisions from foreign courts, international human rights doctrines, or treaty language. If that foreign material supports the judge's preferred outcome, it becomes part of the reasoning. The legislative body that wrote the law never voted. The people never debated it. It arrived through the judiciary dressed in the language of international consensus.
This is not how law is supposed to work in a republic. Law flows from the consent of the governed, expressed through elections and representation. When a judge imports a foreign principle into an American case, the judge is replacing that democratic process with deference to foreign authority.
Legislatures are correct to name this problem. They should go further and prevent it.
The Federalism Question
This also matters for federalism. States have retained sovereignty over family law, property law, and most criminal procedure. When a state legislature establishes that state courts cannot defer to foreign legal systems on these questions, it is reasserting that sovereignty against a kind of judicial imperialism—not from Congress, but from international norms.
The federal courts already have limits on this. The Supreme Court has signaled skepticism of importing foreign law into constitutional interpretation. But the Supreme Court cannot supervise every state court decision. If state legislatures want to make their own position clear, they should do it directly and publicly.
What Constitutional Authority Supports This
States have explicit power here. The Tenth Amendment reserves powers not delegated to the federal government to the states and the people. States control the organization and jurisdiction of their own courts. States define their own property law, family law, and most contract law. A state legislature can certainly tell its courts that foreign legal systems are not a valid source of authority in interpreting state law.
The Constitution does not require American judges to treat foreign law as persuasive, and it certainly does not require them to treat it as binding. A legislative clarification stating that foreign legal systems are not valid authority in state court proceedings is a straightforward exercise of state sovereignty.
The Transparency Argument
There is a secondary benefit here that matters as much as the legal principle. When a judge cites a foreign case or international norm, that citation becomes part of the written record. It is transparent. Everyone can see it. This is not secret. But it is also not debated. The legislature did not authorize it. The electorate did not vote on it.
By writing the rule clearly into statute, legislatures force the conversation into the open. If judges believe foreign law should influence their decisions, they can make that argument. The legislature can respond. The public can weigh in. That is how law is supposed to work.
What Comes Next
Expect more states to follow. Texas has moved in this direction. Other states have signaled interest. The movement will accelerate because the underlying principle is sound: American courts should answer to American law made through American processes.
Legislatures should also consider going further. Beyond prohibiting foreign legal systems as authority, states could require that all major judicial opinions cite only sources found in American law, American precedent, or explicit statutory authorization. That might sound like overreach. It is not. It is the legislature doing its job: defining the authority structure of the courts it created.
Mark the next legislative session in your state. If your house and senate have not explicitly stated that your courts answer to your laws, and not to foreign legal systems, that is a conversation that needs to happen. Write your representative. It is a small thing on the legislative docket. It is a large thing for the principle that law in a free country flows from the people who live under it.
