What can case law be revoked by?

Case law can be revoked or overruled by higher courts through judicial decisions, particularly when a court finds that a previous ruling was incorrectly decided or is no longer applicable due to changes in law or societal norms. Additionally, legislative bodies can effectively revoke case law by enacting statutes that alter or clarify the legal principles established in prior court decisions. Finally, constitutional amendments can also override case law if they change the legal landscape significantly.
