Peaceful settlement of inter-state energy disputes: applicable law, defence arguments, and remedies in the ICC arbitration between Iraq and Turkey

Abstract At this critical juncture in the energy transition dominated by debates over armed conflicts, advisory opinions on climate changes, and investor-State arbitration, it is critical to also consider developments in the peaceful settlement of inter-State energy disputes. One central dispute between the Republic of Iraq and the Republic of Turkey arose out of the Crude Oil Pipeline Agreement for the supply and purchase of crude oil. Iraq filed a request for arbitration in May 2014 under the International Chamber of Commerce Rules of Arbitration. The Tribunal awarded Iraq nearly United States Dollars (USD) 1.5 billion. The Tribunal’s unanimous final award in 2023 discusses fascinating aspects of international energy transactions, including the choice of domestic law in a treaty dispute, defences under the law of treaties, a putative norm of jus cogens to prevent genocide, and possible remedies in an inter-State pipeline arbitration.
