Bulgaria’s Commission on Protection of Competition (CPC) has determined that telecoms operator Vivacom (registered as Bulgarian Telecommunications Company [BTC]) had violated Article 21 of the Law on Protection of Competition. The anti-trust regulator disclosed that fixed line operator Eastern Telecommunications Company (ITC) accused BTC of abusing its dominant position by terminating an interconnection agreement between the two companies and imposing a contractual clause which aimed to only amend the relationship with ITC, thus putting ITC at a disadvantage to its competitors. The CPC pointed out that an analysis has shown that BTC had acted differently in similar cases and that BTC’s decision to amend the interconnection agreement was dictated by its dominant market position. The watchdog highlighted that BTC has the right to submit written objections and provide evidence within 30 days in order to gain access to the case file; the company may also request a hearing in open court. However, CPC’s Determination No. 119 (dated 4 February 2015) is not subject to appeal.
