MOSCOW, March 19 - RAPSI. The Ninth Commercial Court of Appeals will hear on April 23 an appeal in the dispute between the Radio Technical and Information Systems (RTI-Systems) and the antimonopoly service.

The Moscow Commercial Court upheld in February the antimonopoly watchdog's decision to place RTI-Systems on the questionable (mala fide) supplier list. The company filed a lawsuit seeking to cancel the watchdog's decision but lost the case.

RTI-Systems then filed an appeal against the court decision.

The company was placed on the list upon the Service for State Registration, Cadastral Records and Cartography's request.

The service accused the company of evading the signing of a contract for R&D works although it won the bid in 2011. RTI-Systems agreed to provide security equal to 30 percent of the initial contract value before the tender was signed, but failed to do so in a timely manner.

Founded in 2000, RTI-Systems works in radio communications, aerospace control systems and power engineering.
