The 180 days runs out in June. Hearings on a new law are ongoing in Springfield. The proposal on the table, as I understand it, is a NRA backed "shall issue" plan with permits being issued by the Illinois State Police, and no opt out for Chicago--state pre-emption.
The only thing left to find out is whether Madigan will file for cert. I don't know when her time runs on that, but she had originally stated her intent to do so. Obviously, if a bill is signed into law, any such petition would be moot. Further, filing for cert will not stop the clock on the 180 days for the injunction unless she files for and gets a stay.
