An mma sparring match, on private phttps://www.lawguru.com/answers/askroperty, not sanctioned by any athletic commission. Closely monitored by a single referee (who has no qualification beyond a vast knowledge of the sport), adhering to all the rules of a sanctioned event, even extra precautions. Both of the participants being between the ages of 14 and 17, who must orally agree to the following question before each of the three rounds begins, "You both understand that you are fighting of your own free will, and the match will stop at any moment that you signal that you would like it to end?". And who also have had the predetermined rules thoroughly explained to them before they are allowed to fight. Can anyone help me out with the legality of this situation?
