The correct answer is: the Supreme Court, through a new case.
The Supreme Court has the authority to overturn its own precedents when it decides a new case that conflicts with a previous ruling. This can happen if the Court finds that the previous decision was incorrect or if circumstances have changed significantly since the original ruling.
While Congress can pass legislation to address issues related to Supreme Court decisions, they cannot overturn a Supreme Court ruling directly. The President cannot change Supreme Court decisions through executive orders, and states cannot overturn federal Supreme Court precedents through popular vote.
