 The title is a " National " title which means that non @-@ Mexican citizens are prohibited from challenging or holding the championship . As it is a professional wrestling championship , it is not won legitimately ; it is instead won via a scripted ending to a match . The fact that the championship is a " trios " championship means that it 's restricted to Tag teams with three members . The championship is generally not allowed to be defended in any other type of match than a regular match , as is the case for all the Mexican National titles . The commission has been inconsistent on enforcing the rules , in one case they stripped Psicosis of the Mexican National Middleweight Championship for defending it in a hardcore match , in another case they allowed the Mexican National Heavyweight Championship to change hands in a Steel cage match . On occasion single fall title matches have taken place , for example when promoting CMLL title matches in Japan , conforming to the traditions of the local promotion .
