The State Legislatures can make any law, let's say a gun law, outside the jurisdiction of their state courts. CONgress can also make laws outside the jurisdiction of Federal Courts. Its called Jurisdiction stripping.
The Federal and State Legislatures could do this to overcome activists Judges but they do not for this reason: they agree with with the activist Judges but can't let the rubes at home know that.
I prefer Violation of Due Process. :-)
