John Catron,
Permoli v. Municipality Number 1 of New Orleans…
“ What Congress may not forbid Massachusetts to do, it may not forbid Louisiana to do. If Congress may not extend over Massachusetts the provisions of the ordinance of 1787, or any portions thereof, neither can it over Louisiana, or retain them there after Louisiana became Massachusetts's equal, and had the power to decide for herself. If they are retained there they derive their exclusive obligation and force from Louisiana's adoption, and not from the authority of Congress. They have thus become laws of Louisiana, and have ceased to be laws of the United States. ”
