LONDON/MOSCOW (Reuters) - Russian tycoon Oleg Deripaska got a boost on Wednesday in a long-running battle for control of Norilsk Nickel when a high court judge ruled fellow investor Roman Abramovich did not have the right to sell shares in the miner to a third businessman.
Deripaska, who controls aluminum giant Rusal (0486.HK), wants to stop Abramovich from selling Norilsk Nickel (Nornickel) (GMKN.MM) shares to Russian businessman Vladimir Potanin, saying that would violate a 2012 shareholder agreement.
At London’s High Court, Judge Stephen Phillips ruled such a sale by Abramovich, the owner of England’s Chelsea soccer club, breached the terms of that shareholder pact.
He found Abramovich’s company Crispian “was and is precluded under the framework agreement from disposing of shares”.
The judge added the court was adjourned pending applications, including for permission to appeal.
Potanin said in March he purchased a 2 percent stake in Nornickel from Abramovich for about $800 million.
The deal increased Potanin’s holding in the miner to 32.9 percent, but the court said previously the sale could be reversed if the London court ruled in favor of Rusal.
“Rusal is pleased with today’s London court ruling. This completely vindicates Rusal’s decision to challenge the notice,” Rusal said.
Interros, which manages Potanin’s assets, declined to comment. A spokesman for Abramovich was not immediately available for comment.
Rusal, which has been hit by U.S. sanctions since April, holds a 27.8 percent stake in Nornickel. Nornickel competes with Brazil’s Vale (VALE3.SA) for the rank of the world’s top nickel producer and is also the world’s largest palladium producer.
Deripaska and Potanin have periodically been at loggerheads since Rusal, the world’s largest aluminum producer outside China, bought a stake in Nornickel just before the 2008 global financial crash.
Abramovich stepped in as a “white knight” minority shareholder in 2012 to act as a buffer between Potanin and Deripaska.
Deripaska made his first public appearance since being made a target of U.S. sanctions to give evidence to the hearings in May that preceded Wednesday’s judgment.
The judge has yet to detail his reasons, which he said would be published “at a later date”.
