The licensing agency after notice and opportunity for a hearing to the applicant or licensee is authorized to deny, suspend or revoke a license in any case in which it finds that there has been a substantial failure to comply with the requirements established under this chapter. Such notice shall be effected by registered mail, or by personal service setting forth the particular reasons for the proposed action and fixing a date not less than thirty (30) days from the date of such mailing or such service, at which time the applicant or licensee shall be given an opportunity for a prompt and fair hearing. On the basis of any such hearing, or upon default of the applicant or licensee, the licensing agency shall make a determination specifying its findings of fact and conclusions of law. A copy of such determination shall be sent by registered mail or served personally upon the applicant or licensee. The decision revoking, suspending or denying the license or application shall become final thirty (30) days after it is so mailed or served, unless the applicant or licensee, within such thirty (30) day period, appeals the decision to the chancery court in the county in which such facility is located in the manner prescribed in Section 43-11-23, Mississippi Code of 1972. The procedure governing hearings authorized by this section shall be in accordance with rules promulgated by the licensing agency. A full and complete record shall be kept of all proceedings, and all testimony shall be recorded but need not be transcribed unless the decision is appealed pursuant to Section 43-11-23, Mississippi Code of 1972. Witnesses may be subpoenaed by either party. Compensation shall be allowed to witnesses as in cases in the chancery court. Each party shall pay the expense of his own witnesses. The cost of the record shall be paid by the licensing agency provided any other party desiring a copy of the transcript shall pay therefor the reasonable cost of preparing the same.
