Where do they get these people???
You should give the job card to the developer or landowner (who has more clout than you) and send him down to City Hall and demand a written correction with applicable code sections OR sign the card. I promise you something will happen.
The bigger the developer the more power he or she has. I see it happen all the time.
The only way to get rid of this guy is by continued documented complaints that he is not doing his job. It won't be easy and it will require persistence.
You decide if it's worth it.
