The concept of an independent judiciary, rather than legislative supremacy began with the Massachusetts Constitution, and may be an innovation by John Adams. As some may NOT know, in England, there is no constitution. The law is whatever the Parliament passes.
So, if the English parliament votes to eliminate “the right to avoid self incrimination” – this is legal and binding on the courts.
In the United States, “constitutional supremacy”, in this case the 5th Amendment, mean that our congress and our legislature cannot void that particular provision without first amending the constitution.
That all being said, imagine a state of emergency being declared HERE, and the entire United States Supreme Court locked up for declaring that unconstitutional.
Standing up for the principal of an independent judiciary in Pakistan is standing up for democracy everywhere.
