29 C.F.R. § 24.106

(a) Any party who desires review, including judicial review, of the findings and order must file any objections and/or a request for a hearing on the record within 30 days of receipt of the findings and order pursuant to § 24.105(b). The objection and/or request for a hearing must be in writing and state whether the objection is to the findings and/or the order. The date of the postmark, facsimile transmittal, email communication, or electronic submission will be considered to be the date of filing; if the objection is filed in person, by hand-delivery or other means, the objection is filed upon receipt. Objections must be filed with the Chief Administrative Law Judge, U.S. Department of Labor, in accordance with 29 CFR part 18, and copies of the objections must be served at the same time on the other parties of record, the OSHA official who issued the findings and order, the Assistant Secretary, and the Associate Solicitor, Division of Fair Labor Standards, U.S. Department of Labor.

(b) If a timely objection is filed, all provisions of the order will be stayed. If no timely objection is filed with respect to either the findings or the order, the findings and order will become the final decision of the Secretary, not subject to judicial review.
