The legal battle over the city of Seattle’s landmark law that lets drivers for services like Uber and Lyft unionize will continue after a federal appeals court kicked a lawsuit over the legislation back down to a lower court.

The Ninth Circuit Court of Appeals reversed a decision from U.S. District Judge Robert Lasnik last year to dismiss a lawsuit from the U.S. Chamber of Commerce last year, sending the case back down to U.S. District Court. The ordinance has been tied up in a variety of lawsuits for more than two years and hasn’t been able to go into effect.

Uber spokesman Caleb Weaver said in response to the ruling Friday that “the court’s decision is a win for rideshare drivers, riders, and the entire Seattle community.”
