"A decision by the arbitration court is expected within the first half of next year, while a decision on the gas delivery contract is expected sooner, by the end of the first quarter," Naftogaz Business Development Director Yuriy Vitrenko said in an interview with Hromadske.tv.
In June 2014, Gazprom switched Ukraine to a prepayment system for gas supplies over its massive gas debt. The same month, Naftogaz appealed to the Arbitration Court in Stockholm, seeking a retroactive revision of its 2009-19 natural gas transit contract with Russia.
Naftogaz's total claims to Gazprom stand at $26.6 billion, according to the Ukrainian’s company latest data.
In June, Naftogaz sent a proposal to Gazprom to sign an addendum to the existing contract that would allow the Russian company to resume gas deliveries to Ukraine.
