What if a referee assaulted a player? Life ban? well maybe not, but he would never referee a game of rugby again
I am aware of two cases where a referee physically hit a player.
In both situations the referees were suspended immediately by their Society, pending hearings.
In one case (serious assault with little provocation) the referee resigned shortly after the incident and was found guilty
in absentia and banned from all rugby refereeing for life (he was also banned by his County Soccer Refs Association too, based on his rugby pitch incident).
In the other, there had been major provocation by a player, including the first blow. Unfortunately the referee did a lot more than protect himself and injured the player (police action was taken but never got to court). The referee was found guilty of "behaviour un-becoming" and "assaulting a player" - as he had lost all credibility, the Society (and RFU in support) withdrew him from any future Society appointments and both his NFC qualification and CRB clearance was withdrawn by the RFU. He took Coaching Course and has since become a decent 2nd XV coach at his local club.
Neither referee was a Hampshire Society member at any time.
