In December, the Seventh Circuit Court of Appeals held in a 2-1 decision that an Illinois ban on carrying a weapon in public is unconstitutional.
In striking the law, Judge Richard Posner said that Illinois had to provide the court with more than merely a rational basis for asserting that its sweeping ban was justified by an increase in public safety. The court, however, stayed its ruling for 180 days to allow the Illinois legislature to craft a new gun law.
The decision was controversial, particularly after the Sandy Hook school shooting that happened only three days later, but controversy isn't enough to guarantee en banc rehearing. Last week, the Seventh Circuit declined to reconsider its decision.
