The Tennessee Court of Appeals on Friday ruled that the Nashville vote that created a civilian board with the power to investigate police was legitimate, rejecting the police union's challenge and clearing the way for the board to begin work.

In the ruling, the Court of Appeals sided with the Davidson County Circuit Court, which threw out the challenge in September. Nashville voters in November approved the formation of a community oversight board while the appeal was pending.

Advocacy group Community Oversight Now gathered signatures to put the issue on the Nov. 6 ballot.
