CHICAGO (CBS) — Cook County Circuit Court Clerk Dorothy Brown has been booted from the ballot for mayor of Chicago, four days after a hearing officer at the Chicago Board of Election Commissioners determined she didn’t have enough valid signatures on her nominating petitions.

The board voted Tuesday to remove Brown for the ballot, according to spokesman Jim Allen. The decision leaves 14 candidates on the ballot.

A hearing officer last week determined Brown was more than 900 signatures short of the 12,500 required to appear on the ballot for the Feb. 26 election.

Two other mayoral candidates, Cook County Board President Toni Preckwinkle and businessman Willie Wilson, had challenged Brown’s petitions. Wilson withdrew his challenge last week, but Preckwinkle did not.

Tech entrepreneur Neal Sales-Griffin also had faced a challenge from Wilson. Although Wilson also withdrew that challenge, a hearing officer ruled the board would have to consider it, due to evidence Sales-Griffin did not have sufficient valid signatures.

The board voted Wilson’s challenge was not in good faith, and kept Sales-Griffin on the ballot.

These are the 14 candidates who will appear on the ballot:

• Former Chicago Board of Education President Gery Chico,
• Former White House chief of staff and Commerce Secretary Bill Daley,
• Attorney and policy consultant Amara Enyia,
• Former Ald. Bob Fioretti,
• Illinois State Rep. La Shawn Ford,
• South Side attorney Jerry Joyce,
• Former City Council candidate John Kolar,
• Former federal prosecutor and Chicago Police Board President Lori Lightfoot,
• Former Chicago Police Supt. Garry McCarthy,
• Illinois State Comptroller Susana Mendoza,
• Cook County Board President Toni Preckwinkle,
• Former Chicago Public Schools CEO Paul Vallas.
• Tech entrepreneur Neal Sales-Griffin,
• Businessman Willie Wilson.
