Ah. Well, this is one limited case I think it is actually true. I don't think this applies to the vast majority of situations.
When looking at the code I noticed plenty of guidelines and restrictions on who can/can not set speed limits and to what level, so no, "they" cannot just set it to any amount they please. I also noticed restrictions on setting the limits. I may look back at it later when I have time.
That's my point, actually, that the State must prove the speed limit is a prudent guideline of safety, and this is normally done with an engineering survey. If that doesn't exist, there is no "teeth" to the limit and it's considered a speed trap.
To tl;dr, the speed limit has to be backed with a traffic engineering survey. If it isn't, the limit can be contested, and so can tickets resulting from it.
