Article 23

1. Any Contracting State may submit to an international arbitration tribunal any dispute concerning the Organisation or an employee of the European Patent Office or an expert performing functions for or on its behalf, in so far as the Organisation or the employees and experts have claimed a privilege or an immunity under this Protocol in circumstances where that immunity has not been waived.

2. If a Contracting State intends to submit a dispute to arbitration, it shall notify the Chairman of the Administrative Council, who shall forthwith inform each Contracting State of such notification.

3. The procedure laid down in paragraph 1 of this Article shall not apply to disputes between the Organisation and the employees or experts in respect of the Service Regulations or conditions of employment or, with regard to the employees, the Pension Scheme Regulations.

4. No appeal shall lie against the award of the arbitration tribunal, which shall be final; it shall be binding on the parties. In case of dispute concerning the import or scope of the award, it shall be incumbent upon the arbitration tribunal to interpret it on request by either party.
