What is being said here is basically the tautological truth that official government acts are indeed the official government acts, generally with some mechanism such as signing, publishing in an official gazette or something like that. Not that government can define reality. Your Trump example in the other post is the most interesting because Trump actually created confusion on this point, by tweeting random stuff about acts that he then would never follow the proper channels for etc.
