29 CFR 825.403 Appealing the assessment of a penalty for willful violation of the posting requirement.

(a) An employer may obtain a review of the assessment of penalty from the Wage and Hour Regional Administrator for the region in which the alleged violation(s) occurred. If the employer does not seek such a review or fails to do so in a timely manner, the notice of the penalty constitutes the final ruling of the Secretary of Labor.

(b) To obtain review, an employer may file a petition with the Wage and Hour Regional Administrator for the region in which the alleged violations occurred. No particular form of petition for review is required, except that the petition must be in writing, should contain the legal and factual bases for the petition, and must be mailed to the Regional Administrator within 15 days of receipt of the notice of penalty. The employer may request an oral hearing which may be conducted by telephone.

(c) The decision of the Regional Administrator constitutes the final order of the Secretary.
