My ds is immune to any sort of behaviour management whatsoever. He talks back and has a will of iron. Once when I was desperate and exhausted and so so fed up at the end of a very long day he once again committed a serious offence. I marched downstairs and smashed his lego structure up. It had taken him a week to complete and he was devastated. He has not committed that particular offence since.
Not really something to be proud of but it did have the desired effect. He does whatever it is he wants to do and then relies on talking his way out of it afterwards.
As a result I set strict boundaries but let the little stuff go. I definetely choose my battles. He is very confrontational and enjoys a good row!
