10.3 REPEATED INFRINGEMENTS
(a) Repeatedly offending. A player must not repeatedly infringe any Law. Repeated infringement is a matter of fact. The question of whether or not the player intended to infringe is irrelevant.
Sanction: Penalty kick
A player penalised for repeated infringements must be cautioned and temporarily suspended.
(b) Repeated infringements by the team. When different players of the same team repeatedly commit the same offence, the referee must decide whether or not this amounts to repeated infringement. If it does, the referee gives a general warning to the team and if they then repeat the offence, the referee cautions and temporarily suspends the guilty player(s). If a player of that same team then repeats the offence the referee sends off the guilty player(s).
Sanction: Penalty kick
A penalty try must be awarded if the offence prevents a try that would probably otherwise have been scored.
(c) Repeated infringements: standard applied by referee. When the referee decides how many offences constitute repeated infringement, the referee must always apply a strict standard in representative and senior matches. When a player offends three times the referee must caution that player.
The referee may relax this standard in junior or minor matches, where infringements may be the result of poor knowledge of the Laws or lack of skill.
