Is the SCOTUS held by lower court stare decisis? No, so why are they hesitant to deal with a multiple issue case?
There is a hierarchy. If the 9th Circuit (for instance) decides a certain way that prescedent is valid for that specific circuit. IANAL, but that’s my best knowledge. Obviously when the Supes decide its supposed to be valid for all.
This is not a multiple issue case. It's about handguns banned in a city that allows rifles and shotguns kept in the home if they are disassembled or lacked.
The Cert by the SCOTUS is to answer this question only. Nothing more, nothing less.
Each one of the laws we have to change will need it's own challenge, one that can win in the SCOTUS. Heller is a first step.
We are not going to get it all this time around. No matter how hard anyone wishes it.
