What is legal citation checker?
A legal citation checker tells you whether a case is still good law, meaning it has not been reversed, overruled, or seriously questioned by later courts. Casesearch shows a treatment signal on every authority, followed, questioned, or overruled, and links you to the later opinions that treated it, so you confirm a precedent is alive before relying on it in a brief.
