Common sense prevails.
However, regardless of the circumstances, this is entirely irrelevant:
"A character reference from Wasps coach Lee Blackett was provided to the panel. He is a very experienced international player, playing over 100 Super Rugby games for the Hurricanes, including many as captain. He has played over 50 games for Wasps and is currently team captain. He has won eight international caps for England."
A character reference from his own head coach??? How is that even admissible as part of the process? And with all that experience, some would say he ought to know better than a young lad fresh out of the academy getting pinged for the same. In this instance it's academic as a ban was rightly deemed disproportionate, but there will be (and have been) other more serious cases where such information would be taken into account. Nonsense.
