‘In light of the foregoing, on the proper construction of the Arbitration Agreement (contained in Article 22 of the GSPC), as a matter of applicable Iranian law, the determination of the existence and/or extent of CGC’s liability to CNGC under the terms of the CGC-CNGC GSA were not matters within the scope of the Arbitration Agreement. Whether and to what extent CGC was liable to CNGC were controversies that arose out of and related to a separate contract between separate parties and, on the true construction of the Arbitration Agreement in accordance with Iranian law, they were not matters that arose out of or related to the GSPC. They were not therefore matters which could be submitted to the Arbitration in accordance with the Arbitration Agreement within the meaning of Section 30(1)(c) of the Act. As a matter of Iranian law, the Tribunal exceeded its substantive jurisdiction, and its determination as to the existence and/or amount of CGC’s alleged liability to CNGC under the CGC-CNGC GSA are void and/or of no effect. In this regard NIOC relies upon the Expert Report on Iranian law of Dr Ali Mohammad Mokarrami dated25 October 2021 .’
