CHATTANOOGA (WRCB) - Some residents of Elder Mountain are questioning a vote to de-annex the area from the city of Chattanooga.

They're taking legal action.

The de-annexation's passing came down to one vote on the August 3rd ballot. But, some residents claim there were errors.

Only residents of Elder Mountain were allowed to vote.

Those filing the suit claim a list of names the city provided to the Election Commission was inaccurate not listing some eligible voters and listing some who were ineligible.

City Council members approved the de-annexation saying the city doesn't offer enough services to Elder Mountain.

Some residents say they depend on city salting on the mountain road during the winter.
