Politicians do not make the rules.
Politicians collectively put forward rules which are debated and passed by Parliament and the House of Lords.
Once a law is passed by Parliament, judges than pass judgement on the rule and application of the law.
What you say is precisely the problem. A handful of politicians lead by Theresa May and her cabinet wishes to negotiate behind closed doors, making up rules on all our behalf, introducing change of law without Parliament getting a look in.
I also think it is abominable that politicians and media acting remarkably in contempt of court with their outrageous remarks belittling British democracy.
The circus is really in town tonight with Guy Fawkes night.
