A. Any person whose rights, duties, or privileges, including matters relating to licenses, shellfish planting grounds, or fishing stands, have been or may be affected by any action or inaction of the Commission or Commissioner without a formal hearing may demand in writing a formal hearing of his complaint. The Commission shall hold a hearing on the complaint as soon as practicable. All known interested parties shall be afforded an opportunity to be heard before the Commission. All persons who have noted their interest with the Commission shall be informed of the hearing by first class mail at least five days prior to the scheduled date of the hearing. The notice shall indicate the time and place of the hearing and the issues involved. All parties shall have the opportunity to present evidence and argument. The proponents for any regulation or matter shall be heard first, then the opponents. The Commissioner, if present, or any member of the Commission, in his absence, shall preside over the hearing. The rules of evidence shall apply insofar as possible. Depositions may be taken and read as in actions at law.
