21.7 What the opposing team must do at a penalty kick
Must run from the mark. The opposing team must immediately run towards their own goal line until they are at least 10 metres away from the mark for the penalty kick, or until they have reached their goal line if that is nearer the mark.
Must keep running. Even if the penalty kick is taken and the kicker’s team is playing the ball, opposing players must keep running until they have retired the necessary distance. They must not take part in the game until they have done so.
Kick taken quickly. If the penalty kick is taken so quickly that opponents have no opportunity to retire, they will not be penalised for this. However, they must continue to retire as described in 21.7(b) above or until a team-mate who was 10 metres from the mark has run in front of them, before they take part in the game.
Interference. The opposing team must not do anything to delay the penalty kick or obstruct the kicker. They must not intentionally take, throw or kick the ball out of reach of the kicker or the kicker’s team mates.
Sanction: Any infringement by the opposing team results in a second penalty kick, 10 metres in front of the mark for the first kick. This mark must not be within 5 metres of the goal line. Any player may take the kick. The kicker may change the type of kick and may choose to kick at goal. If the referee awards a second penalty kick, the second penalty kick is not taken before the referee has made the mark indicating the place of the penalty.
