If you receive a written denial from ATF, you may either file a request for reconsideration with the ATF Office of Chief Counsel Litigation Division or you may file suit in an appropriate U.S. District Court. Either option must be exercised no later than six months after the date of mailing of the written denial. A request for reconsideration should include a written explanation as to why the matter should be reconsidered, such as new or additional evidence. A request for reconsideration gives ATF another six months to adjudicate your claim. If a request for reconsideration is subsequently denied, you may file suit in an appropriate U.S. District Court no later than six months after the date of mailing of the subsequent denial. If ATF has not adjudicated your request for reconsideration within six months, you may elect to treat the request as having been denied and file suit in an appropriate U.S. District Court.
