An interesting observation. So what happens to someone who gets caught carrying in Illinois tomorrow, or today for that matter. The 7th has said that Illinois' failure to have provisions for any form of carry is unconstitutional. If it's unconstitutional, then the law is unenforceable. The legislature has 180 days to enact a carry statute, but the current law isn't constitutional for another 180 days, it's unconstitutional NOW.
The CA7 gave a stay for the current law until either 180 days is up, or another law is drafted (whichever comes first). Even though technically they called the law unconstitutional, it is still illegal to carry during the stay.
