The title has been declared vacant twice because one of the champions (El Canek and Silver King respectively) left CMLL, and four times due to a major injury to one of the champions. On one occasion CMLL held up the championship, vacating the championship until a rematch between the teams of Místico/Héctor Garza and Averno/Mephisto, a match that Místico and Héctor Garza won to become two-times champions.
