HARTFORD, Conn. (AP) Connecticut's new gun law is being challenged again in court, with a national industry group claiming the legislation was passed illegally without proper public input or adequate review by state legislators.

The National Shooting Sports Foundation Inc. filed the lawsuit Monday in U.S. District Court against Gov. Dannel P. Malloy and other top state officials. The organization wants a judge to strike down the law as invalid.

The General Assembly passed emergency legislation in April expanding Connecticut's assault weapons ban and background check requirements in the wake of the Sandy Hook Elementary School shooting.

But foundation senior vice president and general counsel Lawrence Keane says there was no emergency or statement of facts given that would allow the bill to bypass the traditional public hearing process.

The Attorney General's Office has not been served and declined to comment.
