Article 27 of the GCC Common Excise Tax Agreement outlines the procedure for resolving disputes between Member States. The primary mechanism stipulated is amicable resolution, requiring states to first endeavour to settle any disagreements concerning the Agreement's application or interpretation through mutual discussion and negotiation. Should these diplomatic efforts fail to produce a settlement, the Article provides a secondary recourse. By mutual agreement, the disputing Member States may refer the matter to arbitration. The specific procedures and rules governing such arbitration are not predefined within the Agreement but are to be mutually agreed upon by the parties involved in the dispute.
