Whenever the Treasurer deems that it will increase the salability or the price of the notes to obtain, prior to or after sale, a legal opinion, other than that of the Attorney General, as to the validity or tax-exempt nature of the notes, the Treasurer may obtain that legal opinion. Payment for those legal services shall be made from the proceeds of the sale of the notes.
