1956. The NWA ceased to acknowledge Burke as the Women's World champion in 1954, and instead acknowledged June Byers as champion after a controversial finish to a high-profile match between Burke and Byers that year. Upon Byers's retirement in 1964, The Fabulous Moolah, who won a junior heavyweight version of the NWA World Women's Championship (the predecessor to the WWE Women's Championship) in a tournament back in 1958, was recognized by most NWA promoters as champion by default. Intergender For most of its history, men and women rarely worked against each other in professional wrestling, as it was deemed to be unfair and unchivalrous. Andy Kaufman used this to gain notoriety when he created an Intergender Championship and declared it open to any female challenger. This led to a long (worked) feud with Jerry Lawler. Cathy Davis sued the New York State Athletic Commission (NYSAC) in 1977 because she was denied a boxing license because she was a woman, and the case was decided in her favor later that year, with the judge invalidating New York State rule number 205.15, which stated, "No woman may be licensed as a boxer or second or licensed to compete in any wrestling exhibition with men." In his opinion the judge cited the precedent set by Garrett v. New York State Athletic Commission (1975), which "found the regulation invalid under the equal protection clauses of the State and Federal Constitutions". The NYSAC filed an appeal of the ruling, but later dropped it. In the 1980s, mixed tag team matches began to take place, with a male and female on each team and a rule stating that each wrestler could only attack the opponent of the same gender. If a tag was made, the other team had to automatically switch their legal wrestler as well. Despite these restrictions, many mixed tag matches do feature some physical interaction between participants of different genders. For example, a heel may take a cheap shot at the female wrestler of the opposing team to draw a negative crowd reaction. In lucha libre, cheap shots and male-female attacks are not uncommon. Intergender singles bouts were first fought on a national level in the 1990s. This began with Luna Vachon, who faced men in ECW and WWF. Later, Chyna became the first female to hold a belt that was not exclusive to women when she won the WWF Intercontinental Championship. Intergender
