A federal appeals court on Thursday upheld a dismissal of a lawsuit challenging the assault rifle ban in Cook County, Ill.

The 7th U.S. Circuit Court of Appeals found that the suit was too similar to a previous failed suit against the city of Highland Park, which is about 25 miles north of Chicago, according to The Chicago Tribune.

The three-judge panel wrote that the plaintiffs “have not come forward with a compelling reason to revisit our previous decision” in the Highland Park case, according to the Tribune.
