NJSC Naftogaz Ukrainy is justified in demanding double compensation from Russia's OAO Gazprom (for losses resulting from anti-monopoly violations in gas transit, the first deputy head of Anti-monopoly Committee of Ukraine, Maria Nizhnik, told journalists in Kyiv on Friday.

"If the Committee establishes facts of violations of anti-monopoly provisions, the organization whose rights are violated, in this case Naftogaz Ukrainy, can file in court for compensation that is equal to the sum twice the damage," she said.

The amount of the damage done to Naftogaz on this score is not subject to disclosure, she said, adding that Naftogaz would independently justify the figure and file for it.

The ongoing litigation between Naftogaz and Gazprom now in Stockholm arbitration is being conducted "on a similar, but not completely identical question," Nizhnik said. "There it concerns violations of provisions of the agreement [the transit contract]," she said.

The Anti-monopoly Committee earlier said it was fining Gazprom UAH 85.966 billion ($3.5 billion) for abusing its monopoly position on Ukraine's natural gas transit market.
