official definitions have at times been overlooked for certain champions. One example of this was when Mephisto, officially listed as , won the CMLL World Welterweight Championship, a weight class with an upper limit. With twelve CMLL-promoted championships labelled as "World" titles, the promotional focus shifts from championship to championship over time with no single championship consistently promoted as the "main" championship; instead CMLL's various major shows feature different weight divisions and are most often headlined by a Lucha de Apuestas ("Bet match") instead of a championship match. From 2013 until June 2016, only two major CMLL shows have featured championship matches: Sin Salida in 2013 and the 2014 Juicio Final show featuring the NWA World Historic Welterweight Championship. Championship matches usually take place under best two-out-of-three falls rules. On occasion, single-fall title matches have taken place, especially when promoting CMLL title matches in Japan, conforming to the traditions of the local promotion, illustrated by Jushin Thunder Liger winning the championship during New Japan Pro-Wrestling's Wrestling Dontaku 2010 in a single-fall match. Tournaments 1991 In 1991, CMLL held an eight-man, one-night tournament to crown the first ever CMLL World Middleweight Champion. In the end, Blue Panther won the championship by defeating El Satánico. 1992 Due to a large number of wrestlers leaving the company in the summer of 1992, the middleweight championship was vacated, forcing CMLL to hold a tournament. They opted to start out with a 16-man battle royal elimination match as a means to qualify for the final match the following week. Negro Casas and El Dandy outlasted a field of wrestlers that consisted of Guerrero Maya, Águila Solitaria, Ponzona, Guerrero del Futuro, Plata, Espectro de Ultratumba, Espectro Jr., Oro, Javier Cruz, Kung Fu, Kato Kung Lee, Ringo Mendoza, Bestia Salvaje and Último Dragón. The following week El Dandy defeated Casas to start his first of three championship reigns.
