Ala. Code § 45-58-231.37: Rehearings.

An employee or appointing authority aggrieved by a decision of the board on the original hearing shall be entitled to a rehearing of the issue before the board as provided herein. The aggrieved employee or appointing authority shall make written request upon the board within five days of an adverse decision at the original hearing and the board, within 30 days of receipt of a request for rehearing, shall hold the rehearing in substantially the same manner as the original hearing to review its earlier decision. If, on rehearing, the employee or appointing authority is aggrieved by the board’s decision the employee or appointing authority may appeal the decision to the Circuit Court of Shelby County in equity within 30 days from the rendition of the decision by the board. Review by the court shall be without a jury and be confined to the record, and to a determination of the questions of law presented.
