MOSCOW (Reuters) - A Russian court has ordered a new hearing into a $13 billion lawsuit brought against BP (BP.L) by minority shareholders in its Russia's venture, TNK-BP TNBP.MM, over a failed deal between BP and Rosneft (ROSN.MM), a BP lawyer said on Monday.
The Federal Arbitration Court in the Siberian city of Tyumen has ordered a new hearing in a lower court, lawyer Konstantin Lukoyanov told Reuters. The original suit was thrown out last year.
"Today's decision casts doubts over the domestic court system's ability to create a predictable and effective legal environment," Lukoyanov said, adding it "inflicts substantial damage on Russia's investment climate".
The ruling comes amid renewed hostilities between TNK-BP's co-owners, BP and a quartet of billionaire investors, that escalated last Friday when BP said it would seek to sell its stake after receiving expressions of interest.
A spokesman for the AAR consortium, which represents the shareholder quartet, declined to comment. The group had previously denied being a party to the minority shareholders' lawsuit against the British major.
The minority shareholders claimed that TNK-BP suffered financial losses because it had been excluded from a planned strategic alliance unveiled last year between BP and Rosneft.
No date for the hearings has been set.
