Concept:
The German phrase "Kompetenz-Kompetenz" (Competence-Competence) refers to the authority of an arbitral tribunal to determine its own scope of authority, specifically whether it has the jurisdiction to hear the dispute in question.
Step 1: The functional necessity of this principle.
Without this principle, every time a party questioned whether the tribunal had the legal right to preside over a specific dispute (jurisdictional challenge), the proceedings would have to halt and wait for a national court to intervene. This would lead to massive delays and allow parties to misuse jurisdictional challenges to obstruct the process.
Step 2: Operationalizing Kompetenz-Kompetenz.
This principle grants the tribunal the "competence to determine its own competence." The tribunal can receive evidence and arguments regarding its jurisdiction and issue a preliminary ruling. While this ruling can often be reviewed by a court later, it allows the arbitration to proceed efficiently in the first instance.
Step 3: Conclusion.
It is the power of the arbitral tribunal to rule on its own jurisdiction, which is a vital safeguard for the autonomy and efficiency of arbitration.
