A special court in Kazakhstan has overturned its earlier ruling allowing Ukraine’s state oil and gas company Naftogaz to collect a $1.4 billion international arbitration award from Russia’s Gazprom.

In May, a court at the Astana International Financial Centre (AIFC) recognized and upheld a Swiss International Commercial Court (ICC) arbitration award in favor of Naftogaz.

Shortly after, Kazakhstan’s justice ministry said it would not enforce that decision, arguing that it has “no legal connection to the country.”

On Tuesday, an AIFC judge threw out the special court’s original ruling on the basis that it had no jurisdiction to enforce the award. Naftogaz and Gazprom were told to submit written arguments on costs within 14 days.

The underlying commercial dispute stems from a 2019 contract covering Russian natural gas transit through Ukraine. Following Russia’s invasion in 2022, transit through the Sokhranivka distribution station in the eastern Luhansk region was suspended, though deliveries continued through the Sudzha entry point.
