Victory in intermediate rates of mobile telephony for Telefónica Group in the Supreme Court of Justice, 2012

Represented Telefónica Group, one of the largest telecommunications conglomerates in the world. The Mexican Supreme Court of Justice determined that the mobile completion rates that the Secretariat of Communications and Transportation had set for Telefónica Group should be cancelled. The Supreme Court judgment set a precedent for the telecommunications sector in Mexico, since it recognized the full independence of the defunct Federal Telecommunications Commission from the Secretariat of Communications and Transportation in interconnection issues.

Federal Court declared unconstitutional the Fundamental Technical Plan of Interconnection and Interoperability

Represented Telefónica Group against several provisions of the above general regulation issued by the defunct Federal Telecommunications Commission, which were declared unconstitutional.
