Who Protects Us From Our Guardians?

Assuming that judicial review of democratically-enacted laws is here to stay–and one commentator refers to the doctrine of judicial review as “an irreversible reality of American law”–how are we to protect ourselves from an abuse of judicial review?

If the Court is our Guardian against Legislative Tyranny, who (or what) is our Guardian against Judicial Tyranny?

Does the fact that the Constitution is a written Constitution protect us, because the Court is bound by the Written Constitution? Does it depend upon whether the Court is faithful to the original meaning of the ratified text of the Constitution?
