The referee have discretionary power to stop the game for any infringement of the laws and to suspend or terminate the game whenever by reasons of the elements, interference by spectators or other cause, he deems such stoppage necessary. If any player behaves in a displeased manner, the referee can suspend him from further participation in the game. In both the cases he call submit a detailed report to the competent authority within the stipulated time. The referee cannot allow anybody other than the players and linesmen to enter the field without his permission.

He can stop the game if a player has seriously injured and immediately resume the game as soon as the player is removed from the field. He can send off the field any player who is guilty of violent conduct, serious foul play or the use of foul and abusive language.
