The one judge who said that the Seventh Circuit decision is not binding on state courts is right, but for the wrong reasons. He is right only because the 7th has not yet issued an injunction barring enforcement of the carry ban. If and when it does so, you can bet your bippy that the decision will be binding on all state government, including the courts.
Which leaves an interesting question. We are down to a couple of months before the decision becomes final, and it won't if Illinois passes a carry bill. So what is the status? I haven't heard anything in weeks other than that hearings were being scheduled.
