Whatever the rules say is legitimate?
Let me turn that question around for you: do you think it should be a state requirement that one respects the police in order to run a private business?
You can “turn it round” as many times as you like.
If he breached what the rules currently allow, then his license doesn’t get renewed.
And to repeat myself again, you have no idea what he said, or about who, you don’t know what the rules say either.
So come back when you have all the relevant information and ask me the same question ?
Maybe it will be clearer then what’s happened.
Until then you/we are just guessing, and I can’t really see the point in that to be honest.
