Judicial estoppel

• abstract: In the practice of law, judicial estoppel (also known as estoppel by inconsistent positions) is an estoppel which precludes a party from taking a position in a case which is contrary to a position they have taken in earlier legal proceedings. Although, in the United States, it is only a part of common law and therefore not sharply defined, it is generally agreed that it can only be cited if the party in question successfully maintained its position in the earlier proceedings and benefited from it.
