On the topic of laws being not created by our parliament, most of our own laws that govern us have never been passed by Parliament. They are created by Statutory Instrument. Statutory instruments cover everything: from
the Criminal Procedure Rules, to the laws relating to the construction and use of motor vehicles (loads, lighting) etc, to the laws governing Heathrow Airport and much else, practically every area of life involving any law has some Instrument covering it. And these Instruments often create offences punishable by the criminal courts.
This is termed delegated legislation. It is not created by Parliament, but by bureaucrats in the relevant government department, the minister merely signing it. The one limit; the power to annul within 40 days,is almost never exercised by Parliament. The last instance of an instrument being annulled by the Commons was in 1979, and was about rules governing paraffin, and earlier instances are very rare.
Nearly all such Instruments are created because an Act of Parliament gives the minister the power to make them, this power being expressed in very broad terms e.g the minister shall make regulations concerning airports, or road traffic or whatever. What regulations are made pursuant to that is entirely a matter for the civil servants who draft them to be signed off by the minister
So next time someone complains about bureaucrats in Brussels, they might consider how undemocratic, though convenient, are the laws made by our bureaucrats
