Rugby union match officials are responsible for enforcing the rugby union laws of the game during a match and imposing sanctions on individuals who do not follow the rules. "Every match is under the control of match officials who consist of the referee and two touch judges or assistant referees." Further officials can be authorised depending on the level and form of the game. When the game of rugby union was developed at Rugby school, there were no official rugby referees. It was not until many years later when the game begun to spread internationally that an official was included. Before the creation of rugby referees, the captains from both teams would set the rules down before the game began. The two captains would arbitrate the game together as it went on. Interestingly, this is where the advantage'' law comes from in rugby union. This was because a team''s captain was not likely to complain or stop play if his side actually benefited from the other team''s infringement.
