Kompetenz-kompetenz
Kompetenz-kompetenz, or competence-competence, is a jurisprudential doctrine whereby a legal body, such as a court or arbitral tribunal, may have competence, or jurisdiction, to rule as to the extent of its own competence on an issue before it. The concept arose in the Federal [Constitutional Court of Germany]. Since then, kompetenz-kompetenz has often been important in international arbitration.
