KIEV, April 8 – Naftogaz Ukrayiny could challenge an intermediate decision by the tribunal of the Arbitration Institute of the Stockholm Chamber of Commerce on a claim by Swiss-based RosUkrEnergo gas trader against JSC Naftogaz Ukrayiny for payment by the Ukrainian company of $197 million to the plaintiff in the Svea Court of Appeal, according to lawyers polled by Interfax-Ukraine.

"The Swedish Arbitration Act of 1999 foresees certain possibilities to challenge decisions in courts of appeal within the jurisdiction of the place the arbitration hearing was held. If the place of the arbitration hearings is not indicated, the decision could be challenged in the Svea Court of Appeal in Stockholm," a lawyer of the Pavlenko and Poberezhniuk law firm, Anna Kombikova, said.
