The Chicago Tribune reports that the move is aimed at challenging the decision by a three-judge panel of the court, which ruled 2-1 that the state's longtime ban violated the Second Amendment.
If the court accepts the petition, the case would be reviewed by all 10 appellate judges. If the court rejects the petition, Madigan would have to decide whether to appeal to the U.S. Supreme Court.
"In ruling that Illinois must allow individuals to carry ready-to-use firearms in public, the 7th Circuit Court’s decision goes beyond what the U.S. Supreme Court has held and conflicts with decisions by two other federal appellate courts." Madigan said in a statement issued today. "Based on those decisions, it is appropriate to ask the full 7th Circuit to review this case."
December's decision set a 180-day deadline for the Illinois legislature to draft and enact new laws relating to carrying ready-to-use firearms in public. Today’s petition by the attorney general does not affect that deadline.
