D.C. Mun. Regs. r. 3-5522
A motion for reconsideration, rehearing, or re-argument of a final decision in a contested case proceeding pursuant to § 5517 shall be filed by a party within ten (10) days of the order having become final. The motion shall be served upon all other parties. The Board shall not receive or consider any motion for reconsideration, rehearing, or re-argument of a final decision in a contested case proceeding that is filed prior to the order having become final.
A motion for reconsideration, rehearing, or re-argument shall state specifically the respects in which the final decision is claimed to be erroneous, the grounds of the motion, and the relief sought.
Within seven (7) days after a motion has been filed and served, any other party may file a response in opposition to or in support of the motion.
Neither the filing nor the granting of the motion shall stay a decision unless the Board orders otherwise.
A motion for reconsideration, rehearing, or re-argument shall not be a prerequisite to judicial review.
