Russia's consumer rights society is suing the venue in Moscow where German pop-rock act Tokio Hotel's appearance was canceled last month.

The consumer rights society (OZPP) filed a law suit with Moscow's Meshchansky court against the Olimpiisky sports center, where they show was scheduled to be held on March 10, OZPP said in a statement published on its Web site.

"Audiences were not notified about the cancelation in advance", the organization said, adding that people who had tickets have not been reimbursed so far. OZPP also said that it is suing the venue rather than the promoter, Top Concert, because it was the only company mentioned on the tickets.

According to OZPP, the exact number of people who purchased tickets at between 1,500 roubles ($52) and 22,000 roubles ($759) is not known, but there are "several thousand" who should be reimbursed.

In accordance with the Russian law, OZPP cannot claim a particular sum of money in damages from Olimpiisky, but if the court upholds the claim, everyone who purchased a ticket will have to be reimbursed by the venue.

Top Concert - a major player in the Russian live market, which also promoted shows by Prodigy, a-ha and Franz Ferdinand - put the blame on the cancelation of Tokio Hotel's Moscow show and another scheduled to be held in St Petersburg on March 8 on the artist's management. The company would not respond to Billboard.biz's request for comments regarding OZPP's law suit.

Meanwhile, the Russian business daily Kommersant reported that Top Concert has renewed negotiations with Tokio Hotel's management and that the band's show in Moscow might still take place later this year.
