Let's clear up some things...
Lisa Madigan (Il AG) has petitioned the court for more time to decide to file for en banc (a rehearing before the entire court, instead of the 3 judge panel). The court agreed and gave her until Jan 8th to file... or not. Meanwhile, the 90 day clock to file a petition before the Supreme Court is running.
Judge Posner did not order the Il Legislature to provide a CC law. In a 2-1 decision, the panel found the Il carry laws unconstitutional, reversed the lower (district) courts and remanded the cases back to them with the mandate to enter a declaration of the laws unconstitutionality and issue a permanent injunction.
However, the appeals court stayed its mandate for 180 days to allow the Il Legislature to pass appropriate legislation to allow carry in some constitutional form.
The assumption of many, is that this will be a CC law, instead of simple open carry (something none of the Chicago elite wants - they want that less than some CC law).
Whether or not you get a law like NY/MD or even CA, is up in the air. Whether or not the panel will accept such a law is up in the air (given the criticism by Judge Posner in the Kachalsky decision).
That's where you (in Il) stand, at the moment.
