What recourse does a supporter of a law have if the United States Supreme Court has found the law unconstitutional?
Appeal the case to the United States Senate; if two thirds of the Senate votes to affirm the law, the Court ruling is overturned.
Ask the President of the United States to veto the ruling; then, unless Congress overturns the veto, the Court’s ruling is nullified.
There is no recourse once the Supreme Court has ruled, other than to pass a similar law in the hopes that future Courts defy stare decisis.
Ask the United Nations to overturn the Court ruling; as a global lawmaking body, it overrules federal decisions, as per the Supremacy Doctrine.
