Can an international arbitration tribunal decide on its own jurisdiction?

The international arbitral tribunal has the power to decide on its own jurisdiction, including on the exceptions relating to the existence or validity of the arbitration agreement. For this purpose, an arbitration clause that is part of a contract will be considered as an independent agreement from the other terms of the contract. The decision of the arbitration tribunal deciding that the contract is null shall not ipso jure imply to the nullity of the arbitration clause.
