MOSCOW, November 3 - RAPSI, Alyona Yegorova. A commercial court will hear on December 13 a major Moscow department store's lawsuit against the antimonopoly service, the court told the Russian Legal Information Agency (RAPSI) on Thursday.

The court held a preliminary hearing on Thursday and found that the case is prepared for the primary hearings.

The TsUM department store filed a lawsuit after the antimonopoly watchdog ordered it in October 2010 to remove an advertisement reading: "-30%; -50%; SALE." The watchdog maintained that its use of English as a foreign language had the potential to mislead customers.

TsUM was ordered to stop using the ad.

The case has gone through three instances.

Founded in 1885, TsUM is the oldest department store in Moscow. TsUM carries more than 1,000 brands of fashionable apparel, perfumery and jewelry.

TsUM's major shareholder is the Mercury Group, which trades luxury goods.
