A person who is adversely affected or aggrieved by an order passed or regulation adopted by the Commissioner under this title may appeal to a court of competent jurisdiction in accordance with the Maryland Rules. The filing of an appeal does not stay an order or regulation of the Commissioner. However, after giving the Commissioner notice and an opportunity for a hearing, the court in which the appeal is pending may stay an order or regulation of the Commissioner on the conditions that the court considers proper. The conditions may include a requirement to post security. A court shall hear the appeal promptly. A regulation that the Commissioner adopts under this subtitle: is prima facie lawful and reasonable; and may not be held invalid because of a technical defect, if there is substantial compliance with this title.
