Is It Legal?
What happens to pending federal court cases?
They are wound down or transferred under rules set in the separation agreement. Pending cases are one of the most ordinary items on the transition agenda, and the answer is the same one every negotiated separation reaches: nothing is dropped, and the rules are agreed in advance so no one is caught by surprise.
This is routine transition work, not a legal cliff
The image of every federal case in Texas vanishing overnight is a scare, not a scenario. Real separations do not work that way. When governments separate, they negotiate exactly how in-progress matters are handled, who finishes them, in which forum, and under which law. The Quebec framework that Canada's own Supreme Court endorsed lists this kind of question, the rights and interests of affected parties, among the standard subjects a separation negotiation settles. It is expected, it is planned for, and it is resolved by agreement rather than left to chance.
Cases sort by what they actually are
The cleanest way to think about pending cases is to ask what each one is really about. A criminal prosecution for conduct that is also a crime under Texas law has a natural home in the Texas criminal courts and can be continued there. A civil dispute between private parties can move to the Texas civil courts, which already hear the full range of civil matters. A matter that is purely an artifact of federal law, or one in which the United States itself is a party, may be wound up in the remaining U.S. system or resolved as part of the separation terms. The sorting is logical, and Texas has a court for every category.
Texas courts can hear all of it
The reason this works is that Texas courts are courts of general jurisdiction. Unlike federal courts, which are limited to the specific kinds of cases the U.S. Constitution allows, Texas trial courts can hear essentially any controversy. That general competence is exactly what a national judiciary needs, and Texas already has it. There is no type of pending dispute that an independent Texas would lack the courts to finish.
The rules are set up front so nobody loses their day in court
The whole purpose of negotiating this in advance is to protect the people whose cases are in progress. A litigant in the middle of a lawsuit, a defendant awaiting trial, a family in a custody fight, all of them need to know their matter will be heard, not erased. So the transition agreement fixes the continuity rules before independence takes legal effect: which court inherits which case, how deadlines and appeals are handled, how records move. Predictability is the goal, and predictability is achievable because both governments want the same thing, an orderly handoff.
Rights travel with the case
Whatever forum a case lands in, the protections around it continue. An independent Texas operates under the Texas Constitution and its Bill of Rights, which guarantees due process and open courts. Moving a case from a federal courtroom to a Texas courtroom does not strip a party of fundamental rights. It changes the letterhead on the building, not the guarantee of a fair hearing.
The bottom line
Pending federal cases are transferred or wound down under rules agreed in the separation, sorted by what each case actually is. Texas courts can hear every category, the continuity rules are set in advance so no one loses their day in court, and due-process protections travel with the case. This is standard transition work, and it has standard solutions.
