"The WRFU judicial review officer considered all facts presented, and along with the WRFU, agreed the issue of the red card was more than sufficient penalty on this occasion.
"The referee was absolutely correct in law, and justifiably suspended the member for repeat infringement, following a number of individual and team warnings for same breaches.
"Therefore, no further action is required, of which all parties have been notified."
The incident was called a "strange postscript late in the game" by Chronicle sports editor Jared Smith, where "referee Mark Wilson sent off Cullinane captain and standout No8 Reggie Boult for impeding the ball at the breakdown by "bridging".
"Wilson had already handed out a yellow card to another Cullinane forward for a similar offence earlier in the second half, along with a St Patrick's forward for rough obstruction after Cullinane had been awarded a penalty on the tryline.
"Wilson had called Boult over for a final warning about his team's bridging before the dismissal, with Boult bending down to demonstrate his players were staying on their feet, but using their hands on the ground to steady themselves, which he interpreted to be legal," Smith wrote.
Cobb said the red carding was justified because in fact it was the sixth card issued to Cullinane after four team infringement warnings and an individual yellow card to another player.
"There has to be a clear message that there are consequences for repeat infringing."
Cobb said the sending off of Boult was considered enough.
"We took into consideration this was the player's actual first infringement for that game, and the fact he was on the back of a number of team warnings.
"We consider the red carding was enough, there was no element of foul play or foul language."
