MOSCOW, June 18 (RAPSI) - Hearings in Russian airline Aeroflot's fraud case against deceased oligarch Boris Berezovsky have been postponed owing to the fact that an administrator has not yet been appointed to Berezovsky's estate, Aeroflot's lawyers told RAPSI Tuesday.

The airline sued Berezovsky and its former deputy director general Nikolai Glushkov alleging large-scale fraud. In 2007, Berezovsky and Glushkov were held jointly and severally liable to pay nearly 215 million ($6.8 million) rubles in damages to the company. 

In 2011, Aeroflot sought an adjustment for inflation. 

The initial sum was around 215 million rubles ($6.8 million). Following the inflation adjustment, it was increased to upwards of two billion rubles.

Aeroflot then turned to the English courts for enforcement.

The London High Court decided last October to grant a summary judgment dismissing the airline's action against the two businessmen, finding that the enforcement of the judgment would breach the principle of res judicata, which precludes the double-litigation of a given topic. 

Aeroflot appealed the decision and a hearing was expected to be held this week. However, it has been postponed until November, as an administrator has not yet been appointed to Berezovsky's estate.

Berezovsky left Russia in 2000, soon after criminal proceedings were launched against him. He never returned to his homeland and was granted political asylum in the UK in 2003. He was found dead in his Berkshire home last March. 

During the inquest into the businessman's death, detective inspector Mark Bissell of the Thames Valley police said Berezovsky had aligature around his neck when his bodyguard found him on the bathroom floor. This led to allegations that Berezovsky might have been killed. It was widely reported in late March, however, that police had not found any evidence implicating third-party involvement.
