I could at least pretend that might happen if there was only one kind of engineer. But someone that incompetent at hiring might also hire the wrong kind of engineer. The rule doesn't do anything to help.

Just to expand, I've never heard of an engineer from the wrong field signing off on a document (e.g. an EE signing off on a structure), but here's a lesser example of unskilled practice and the corresponding disciplinary action: https://www.apega.ca/assets/PDFs/discipline-decisions/18-011...
