Hmmm...
You'll be begging my pardon for misunderstanding or lack of knowledge.
As such applies to the U.S. systems, I was always under the impression that legislative-bound "laws" [especially of the Constitutional variety] can only be introduced, changed or rescinded by the respective legislative body or indirectly the voting population.
The judicial branch merely rules upon or resolves legal disputation.....yet, in practice, seems to be commonplace to revoke or repeal writs created and voted upon by the legislative bodies [the people's representatives]. Any judgement, ruling or legal opinion doesn't reverse the course of the law. It's just interpreted........correct??
If any judicial rulings [or executive rulings] can overturn legislative laws, why bother with a legislative branch?
For you American systematic and constitutional scholars - please educate me.
