That is how you interpret it, but that is not what it says and therefore they are allowed to ban Nutty from the coming 4 NWL events without breaking any rule.
Well, if we're going to follow the same obstinate line. There is no rule that says Nutty cannot play. Therefore he can play (they are the same thing, one is doubly negated of course). They are now changing that rule for 4 matches, however, rule changes by policy only take effect at the change of the season. So there you have it. As you say, this is driving it to the absurd though, since as I said. Implicitly the organizers (when acting in their capacity as organizers) are to act in a way defined by the rules.
If the organizers see the breach of common courtesy as severely enough such a punishment is fully acceptable.
How did you hallucinate this statement up? You may be a douche for not holding the door open for someone, but that does not make you liable to be punished. You may be a douche if you smoke indoors, but that does not make you liable to be punished. However, if there's a law forbidding indoor smoking, you're both a douche and liable to be punished. See the difference?
It's not about a second chance even to be honest, or being misunderstood, or forgiving or forgetting. It's the simplicity of the lack of rule. He is acting within the rules so there's nothing to forgive. People are of course allowed to remember and resent him for doing it of course. I mean, if you really are hellbent on clamping down on this you still have to let Nutty pass, change the rule. (And even then the rule would only take effect next season if it was to be congruent with previous promised rule changes)
