Relating to the authority of the legislature or a state court to declare certain federal actions to be unconstitutional federal actions, including the effect and enforcement of such a declaration.

HB 97, titled the "Texas Sovereignty Act," proposes that the Texas legislature or state courts may declare specific federal actions unconstitutional if they exceed powers delegated to the federal government under the U.S. Constitution. The bill argues that all powers not explicitly granted to the federal government by the Constitution are reserved to the states or the people, and it specifically limits federal authority over intrastate commerce. If enacted, the declaration would be made by Texas state entities, though the bill does not specify how such a declaration would be enforced or its legal effect on federal law. The measure directly affects Texas state government bodies (legislature and courts) and could influence how Texas responds to federal policies it deems overreaching.
