Kazakhstan has been formally notified of an arbitration appeal filed by international stakeholders against a substantial environmental penalty. The appeal challenges a 2.3 trillion tenge ($4.6 billion) fine imposed in 2023 on the North Caspian Operating Company (NCOC), the operator of the giant Kashagan offshore oil field. The notice states the appeal was lodged with the Washington, D.C.-based International Centre for Settlement of Investment Disputes (ICSID) on February 9.

Legal Proceedings and Government Response

The case names several high-ranking Kazakh officials as respondents, including the Prime Minister and the ministers of national economy, environment and natural resources, energy, and justice. The Kazakh Justice Ministry has stated it will provide legal support to the Environmental Ministry, which is leading the government's defense. International law firm Squire Patton Boggs is also listed as a representative for Kazakhstan in the ICSID filing.

Basis of the Environmental Fine and Domestic Litigation

The dispute originates from a fine levied by a regional department of the Environmental & Natural Resources Ministry. The authorities alleged that NCOC significantly exceeded its permitted limits for sulphur storage in 2022 and failed to act on prior warnings to move the sulphur from open-air storage pads to mitigate environmental harm. This penalty has been contested in Kazakh courts since its imposition. In the latest domestic ruling, a special administrative court in Astana rejected an NCOC appeal in December 2023, upholding the full fine but permitting a further appeal to a higher court.

Parties to the Arbitration and Legal Framework

The arbitration has been initiated by the foreign shareholders of NCOC. According to ICSID records, they are represented through wholly-owned subsidiaries. These include subsidiaries of Shell, Eni, TotalEnergies, ExxonMobil, China National Petroleum Corporation (CNPC), and Inpex. Five of these shareholder entities are incorporated in the Netherlands, with ExxonMobil's subsidiary based in the Bahamas and Inpex's in Japan. The appeal is filed under the Energy Charter Treaty, which Kazakhstan ratified in 1995. The case also invokes bilateral investment treaties between Kazakhstan and France (1998) and between Kazakhstan and the Netherlands (2002).
