 The current rules for the Ultimate Fighting Championship were originally established by the New Jersey Athletic Control Board.The "Unified Rules of Mixed Martial Arts" that New Jersey established has been adopted in other states that regulate mixed martial arts, including Nevada, Louisiana and California.These rules are also used by many other promotions within the United States and are mandatory for those states that have adopted the Unified Rules, and so have become the standard "de facto" set of rules for professional mixed martial arts across North America and Europe.
