3. Arbitration Ad-hoc
As a principle, ad-hoc arbitration stipulated in the Treaties would be held by three arbitrators. Each party would appoint one arbitrator whereas the third to be appointed by the other two should in most cases be national of a third country which keeps diplomatic relations with both contracting states. Some of the Treaties stipulate the third arbitrator to be appointed by a respected international institution. Many of the Treaties explicitly refer to UNCITRAL arbitration rules (http://www.uncitral.org/english/texts/arbitration/arb-rules.htm).
