Yeah truthfully I'm surprised his license got suspended - sanctioned maybe, w/ cease & desist order on illegally practicing land surveying. But based on his ridiculous certification sounds like it couldnt have happened to a more deserving d-bag. But yes, as Wilheld said, anything having to do with legal boundary determination or establishment and associated records thereof (stamping maps / plats) falls under the legal authority of professional surveying - not civil / structural engineering.
