Re: Didn't the UK create these rules?
No civil servant in the UK is employed by an elected representative either. That is the point of an independent civil service. This is not the USA where huge swaithes of the civil service are political appointees.
If you care to watch Yes Minister/Yes Prime Minister you will see British civil servants do reasonable job of countering the wishes of the electors too.
The reason that sections of the British press refer to EU civil servants with the pejorative description of unelected is because it suits their rabid anti EU stance.
