 In line with the nature of the dispute, the Court held public deliberations and opened up witness & expert testimony in an unprecedented way.The Instituto Mexicano de la Radio (Grupo IMER) did not agree with this law because they claimed that if approved, all the radio stations of this group, as well as the television stations Once TV, Canal 22, Edusat and TV UNAM would be forced off the air.All the stations of the Grupo IMER then proceeded to broadcast the same song all day.
