Once again, the law contradicts common sense
Same thing happens all the time. A word is used, and has a known meaning. The law comes along and redefines it.. wrongly.
For example, what would you describe as a competent person? Someone who knows what they're doing and generally doesn't cock up?
Nope, in the electrical industry in the UK it means you can be ludicrously bad at your job, but if you're a member of a few select bodies, you are legally 'a competent person'
The law is an ASS (the north american definition, on the grounds it spews a load of shite)
With respect to TFA, anyone who carries out engineering is, by literal definition, an engineer. Licensing be buggered
