You want your government to have a final say. Good luck. The operation of power of both right and left shows the evil that can be perpetrated.
I know there are good Tories who don't believe this stuff. Who won't overthrow something that we did as a nation.
The GRA is primary legislation and can be revised.
Do not listen to the whistlers on immigration and rejection of the ECHR.
They want power for themselves. They will tell you that it's all what the people want. But if you want that, you don't want law that applies fairly, or away from the judiciary.
Law is what separates us from pure power; in this country it gives freedom of speech, a fair trial, freedom from torture and basic rights to life so that governments could not persecute minorities, pick on racial characteristics or sexual preference. It means I can't lawfully be taken away by secret police as is possible in many other countries in the world. And it means that the government, if it wishes to impinge on my rights must justify that in law.
If you are a liberal person you will see this stuff for what it is. I am with the people who ask for answers and what would be better.
This is not some sort of left wing conspiracy. It was done out of a recognition that government, left or right, abuse their power.
