Well, do the same thing by which bachelors are kicked out from the society. Get your Society head and people together and ask them to evict him citing that bachelors/ divorced/ single people are not allowed. Works equally well if he eats non veg and others don’t. Basically, use society rules or laws to get him out.
From what I know, fighting cases is never about following or not following laws but always about an ambiguity or vagueness in a law which can be manipulated. Find a loophole and gather people for your case.
