A doctrine barring evidence about a fact or issue that was subject to prior adjudication from being offered in a subsequent arbitration. This concept is similar to, but different from, res judicata, which involves a contention that the case (and dispute itself) has been the subject of previous resolution and cannot be tried anew. Both principles differ from double jeopardy, a concept borrowed from criminal law that precludes an employer from seeking to discipline an employee twice for the same misconduct.
