MOSCOW, December 14 - RAPSI, Natalia Belova. A shareholder of Baltiysky Zavod shipyard has challenged the court decision to hear the Central Bank's lawsuit to take recourse over the shipyard's shares behind closed doors, the court told the Russian Legal Information Agency (RAPSI/rapsinews.com).

It has yet to be found out whether Nano-Stroy's appeal was accepted or not, a source in the court said.

According to earlier reports the court decided to hear the case behind closed doors after the case was classified. The court adjourned hearings until December 15.

The Central Bank seeks to levy execution on 88.32 percent in Baltiysky Zavod shipyard pledged on July 15, 2010 as a security for Mezhprombank's loans worth 32 billion rubles ($1 billion).

In November the court appointed Ernst & Young to appraise the shipbuilder's shares at the request of the Central Bank, although Nano-Stroy preferred Deloitte & Touche.
