If your landlord does something that they would normally be within their rights to do in retaliation to you enforcing some other provision in your agreement, then it is illegal. I'd bet that this was not the kind of statute that they could override in a lease agreement. I wonder if such a clause is actually enforceable. Are there any actual cases where this clause was invoked?
