A license to act as a stevedore will be issued only upon a verified application submitted on a form furnished by the commission. Each application for a stevedore license shall be accompanied by a personal character information form furnished by the commission, completed and verified by the applicant, by each member of a partnership, and, if the applicant is a corporation, by each officer, each director and each natural person holding, directly or indirectly, five percent or more of any class of capital stock. The commission may, upon examination, require such additional evidence and information as may be required to establish the character of the real parties in interest.
