Bashneft, one of Russia's largest oil producers, is suspected of colluding with LUKOIL and illegally obtaining a license for the Trebs and Titov oil fields. State Duma deputy Sergei Karginov has appealed to the government seeking a return of the oil fields to public control. Bashneft stated that Karginov's information is false and damages the company's business reputation and the investment climate in Russia in general. Bashneft President, Alexander Korsik, has claimed that the allegations have been made in an attempt to manipulate the company's share prices. Bashneft shareholders have filed a lawsuit with the Moscow Commercial Court seeking to invalidate an order that registered the development license for the oil fields in the name of Bashneft's subsidiary, Bashneft-Polyus.
