Carl Redus is the only candidate who filed paperwork to run for the city's top post.
A special judge ruled the election won't be until 2016, but Redus points to a law that changes the election date to this year.
That law says a city with a population under 50,000 people will vote for mayor during the mid-term election. It's the same law Redus argued in court back in 2012, but a judge said the law does not specify changing the election date when there is a population decrease.
The Jefferson County Election Commissioner, who worked as Redus' chief of staff, supports his old boss.
Current Mayor Debe Hollingsworth said she sought an opinion from the secretary of state that the election will be in 2016.
