Russia’s Federal Antimonopoly Service (FAS) has joined cellular operator Vimpelcom in a lawsuit against the recent spectrum awards in the country’s Far East Federal District. Vimpelcom launched the legal action after it won just three of the 24 available concessions in a frequencies tender run by the Ministry of IT and Communications (MinSvyaz) last month. Vimpelcom claims the bidding rules were unfair and were biased towards new entrants such as Summa Telecom, which won twelve of the 15 auctions in which it bid. MinSvyaz maintains its auction rules were fair. The Moscow Arbitration Court has delayed the beginning of the lawsuit until mid-October, CNews reports.
