After Scalia's Death, UK Should Focus on Its High Court

Of course, our Supreme Court has a much narrower jurisdiction than America’s. The UK Supreme Court cannot overturn primary legislation (that is, Acts of Parliament), though it can strike down secondary legislation in some cases. Though the UK Supreme Court can declare legislation incompatible with the European Convention on Human Rights, it is up to the government whether it accepts that declaration and how it proceeds. By contrast, the US Supreme Court can revoke any legislation on grounds of it being unconstitutional.
