(a) This section shall apply to all licenses administered by the Department of Conservation and Natural Resources or any division thereof.

(b) In the event any license for the same privilege is made available at a lesser price and reasonable notice of its availability has not been given to the public, a person, firm or corporation will be entitled to a refund equal to the amount of the reduction of the license fee; and any person, firm or corporation who, by mistake, purchases any duplicate license or pays an amount in excess of that required by law for the license shall be entitled to have the money incorrectly paid refunded as hereinafter provided, less any amount paid as an issuance fee or other fee to any probate judge, license commissioner, special agent or other person authorized to issue such licenses.

(c) Any amount charged by a probate judge, license commissioner, special agent or other person authorized to issue such licenses as an issuance fee or other fee that is in excess of the legal and proper issuance fee must be refunded by the probate judge, license commissioner, special agent or other person charging said illegal fee.

(d) All applications for refund must be made within one year from the date of such erroneous or excessive payment.

(e) The Commissioner of the Department of Conservation and Natural Resources or his duly authorized agent, upon receiving an application for refund and satisfactory proof of duplicate or excessive payment for a license fee, shall authorize refund of the money incorrectly paid, less any legal and proper issuance fee retained by the judge of probate, license commissioner, special agent or other person authorized to issue such licenses. The amount of such refund shall be paid by warrant out of the fund into which it was originally paid in the State Treasury.
