If by reason of any cause beyond control, and through no fault or neglect of any licensee, and while such licensee is not in default, it should become impossible, impracticable or inadvisable for a licensee to hold or conduct racing upon any date or dates licensed by the Commission, the Commission in its discretion and at the request of the licensee shall have power to return the fees paid by the licensee for racing upon the days upon which it is impossible, impracticable or inadvisable for the licensee to hold or conduct racing. The decision of the Commission in this regard shall be final.
