OMAHA, Neb. (AP) — The Nebraska Supreme Court has upheld a finding that Omaha firefighters  can’t legally participate in roadside collections for charities on city time using city-owned uniforms and equipment.

The ruling targets so-called “boot drives,” in which uniformed firefighters ask people at traffic intersections, malls and supermarkets to drop money in firefighters’ work boots to go to organizations like the Muscular Dystrophy Association.

In 2010, the Nebraska Accountability and Disclosure Commission issued an opinion saying the practice violated state law.

The state firefighters union and Muscular Dystrophy Association challenged that finding, and the Lancaster County District Court dismissed the action, saying the court lacked jurisdiction to review a commission advisory opinion.

The Nebraska Court of Appeals agreed, and on Friday, the state’s high court upheld the dismissal for lack of jurisdiction.
