The radio-taxi market is a market where customers through internet facilities can book a taxi to reach their desirable destiny within a reasonable price charged by the aggregator. By using the internet platform, the aggregator enterprises have engaged several taxi owners and drivers and the enterprises are providing these e-taxi services to the consumers. The competition commission, dealt with information alleging anti-competitive-agreement and abuse of dominance when Meru Cabs, one of the radio-taxi service providers, filed information against Uber and OLA too. Commission was of the view that Uber did not do any unfair practice but competition appellate tribunal, the appellate body made an opposite view contrasting to commission. The paper tries to analyse the abuse of collective dominance created by OLA and Uber in the radio-taxi market in India. The paper also highlights the international scenario and laws related to collective dominance in the European market.
