Mexican antitrust body Cofeco (CFC) has ratified a ruling declaring the dominant positions of América Móvil's (NYSE: AMX) fixed-line operator Telmex and mobile unit Telcel in the switch termination market, local paper El Universal reported.
The resolution allows telecoms regulator Cofetel to implement an asymmetric regulatory regime.
The antitrust body began the procedure after Mexican supreme court SCJN determined that it must accept petitions for reconsideration filed by Telmex and Telcel. This is the first of five reviews CFC will have to make after the SCJN resolution to determine Telmex's and Telcel's dominance in the local market.
In 2009, CFC declared that Telmex and Telcel held dominant positions in the local market, and then ratified the resolution in 2010.
