First, all available contracts start with the same basic premises and find that WWE is a licensed combat promotion with global operations that can allow a wrestler, who is himself duly licensed, to introduce himself and attract public attention. After this introduction, 14 sections are described below. As with other professional wrestling promotions, WWE shows are not legitimate competitions, but a performance theatre based solely on entertainment with storyline controlled, scripted and partly choreographed matches, although matches often contain moves that can expose actors to the risk of injury or even death if not performed properly. This was first recognized in 1989 by WWE owner Vince McMahon to avoid taxes from sports commissions. Since the 1980s, WWE has publicly described its product as sports entertainment and recognized the product`s roots in competitive sport and theatre. On May 23, 2012, Total Nonstop Action Wrestling (TNA, now an impact fight) sued former collaborator Brian Wittenstein and WWE. The complaint argued that Wittenstein had violated a confidentiality agreement and had shared confidential information with the WWE, which was a comparative advantage in negotiations with fighting talent under contract with TNA. He was then hired by the WWE, after which TNA claimed that Wittenstein had violated the agreement by downloading confidential TNA trade secrets and passing that information on to WWE. Although WWE fired Wittenstein and informed TNA officials of the disclosure of the information, TNA stated that WWE had access to the information three weeks before and during the disclosure. WWE used secret contract information and attempted to put its talent in violation of the Tennesse Uniform Trade Act.  The appeal was formally withdrawn by TNA on 15 January 2013 following a « Notice of Voluntary Nonsuit », which does not provide for a decision on the merits of the appeal and allows TNA to reappear at a later date.  On May 23, 1999, Owen Hart died in Kansas City, Missouri, during the Over the Edge Pay-Per View, in a stunt gone wrong. WWF broke Kayfabe by constantly repeating to TV commentator Jim Ross to viewers who were live on the payment, that what had just been revealed was not a wrestling angle or a plot and that Hart was seriously injured, underscoring the seriousness of the situation.
 While several attempts were made to resuscitate him, he died of his wounds. The cause of death was later revealed as internal bleeding due to musculoskeletal trauma. WWF management decided to continue the event in a controversial manner.  Later, Jim Ross announced Hart`s death to viewers during payment, but not to the crowd in the arena.  While the show continued, it was never published commercially by WWF Home Video.
