(6) No contest. A bout may be terminated by the referee inside the scheduled distance owing to a material happening outside the responsibility of the boxers, or the control of the referee, such as the ring becoming damaged, the failure of the lighting supply, exceptional weather conditions, etc. In such circumstances the bout shall be declared “no contest” and in the case of championships, the jury shall decide the necessary further action.
(7) Win by walkover. Where the boxer presents themselves in the ring
fully attired for boxing and the opponent fails to appear after the
opponent’s name has been called out by the public address system,
the bell sounded and a maximum period of two minutes has elapsed,
the referee shall declare the first boxer to be the winner by a
walkover. The referee shall first inform the judges to mark their
score cards accordingly, collect them and then summon the boxer to
the center of the ring. After the decision is announced, the referee
raises the boxer’s hand as the winner.

The official in charge or tournament administrator should endeavor to inform the affected boxer as soon as possible.
