KYIV, Dec 17 - A number of investors in the renewable energy sector have already made internal decisions to go to international arbitration if the Constitutional Court of Ukraine recognizes feed-in tariffs on the submission of people's deputies as unconstitutional, lawyer Timur Bondarev, the managing partner of Arzinger law firm, representing the interests of the industry, has said.

"Our company already has at least about ten investors who have made an internal decision to apply to international arbitration if feed-in tariffs are declared unconstitutional," Bondarev said at a press conference at the Interfax-Ukraine agency, adding that one company has already filed a claim in connection with this issue to the Ministry of Justice of Ukraine.
