The Swiss Supreme Court has rejected an appeal from Russia’s Gazprom, upholding a 2025 arbitration ruling that orders the energy giant to pay $1.4 billion to Ukraine’s state energy firm, Naftogaz. This decision pertains to a debt incurred for gas transportation services, along with interest and arbitration costs.

In a statement, Naftogaz emphasized the importance of the Swiss court’s role in affirming the validity of the arbitral award. The court’s decision represents a definitive rejection of Gazprom’s arguments, further cementing Naftogaz’s legal position in the long-standing energy dispute.

Naftogaz CEO Serhiy Koretskyi has expressed commitment to enforcing the ruling, signaling ongoing efforts to secure the stipulated payments from Gazprom. The development marks a significant moment in the ongoing energy disputes between Ukraine and Russia.
