Every person making application for license to hold a race meet, under the provisions of this chapter shall file an application with the commission which shall set forth the time, the place, the number of days such meet will continue, and such other information as the commission may require. The commission shall be the sole judge of whether or not the race meet shall be licensed and the number of days the meet shall continue. No person who has been convicted of any crime involving moral turpitude shall be issued a license, nor shall any license be issued to any person who has violated the terms or provisions of this chapter, or any of the rules and regulations of the commission made pursuant thereto, or who has failed to pay to the commission any or all sums required under the provisions of this chapter. The license shall specify the number of days the race meet shall continue and the number of races per day, which shall include not less than six nor more than eleven live races per day, and for which a fee shall be paid daily in advance of five hundred dollars for each live race day for those licensees which had gross receipts from parimutuel machines in excess of fifty million dollars in the previous year and two hundred dollars for each day for meets which had gross receipts from parimutuel machines at or below fifty million dollars in the previous year; in addition any newly authorized live race meets shall pay two hundred dollars per day for the first year: PROVIDED, That if unforeseen obstacles arise, which prevent the holding, or completion of any race meet, the license fee for the meet, or for a portion which cannot be held may be refunded the licensee, if the commission deems the reasons for failure to hold or complete the race meet sufficient. Any unexpired license held by any person who violates any of the provisions of this chapter, or any of the rules or regulations of the commission made pursuant thereto, or who fails to pay to the commission any and all sums required under the provisions of this chapter, shall be subject to cancellation and revocation by the commission. Such cancellation shall be made only after a summary hearing before the commission, of which three days' notice, in writing, shall be given the licensee, specifying the grounds for the proposed cancellation, and at which hearing the licensee shall be given an opportunity to be heard in opposition to the proposed cancellation.
