The Department of Revenue seeks a writ of prohibition to prevent the Division of Administrative Hearings (“DOAH”) from proceeding with Sheraton’s rule challenge to a repealed rule. The Department contends that section 120.56, Florida Statutes does not authorize a rule challenge to a rule that is no longer in existence, and therefore, DOAH is acting in excess of its jurisdiction. We agree and grant the petition. Because the court is confident that DOAH will promptly comply with this opinion, the court withholds formal issuance of the writ.
