§ 401. Licenses. 1. When licensing is required by law to be preceded by notice and opportunity for hearing, the provisions of this chapter concerning adjudicatory proceedings apply. For purposes of this act, statutes providing an opportunity for hearing shall be deemed to include statutes providing an opportunity to be heard.

2. When a licensee has made timely and sufficient application for the renewal of a license or a new license with reference to any activity of a continuing nature, the existing license does not expire until the application has been finally determined by the agency, and, in case the application is denied or the terms of the new license limited, until the last day for seeking review of the agency order or a later date fixed by order of the reviewing court, provided that this subdivision shall not affect any valid agency action then in effect summarily suspending such license.

3. If the agency finds that public health, safety, or welfare imperatively requires emergency action, and incorporates a finding to that effect in its order, summary suspension of a license may be ordered, effective on the date specified in such order or upon service of a certified copy of such order on the licensee, whichever shall be later, pending proceedings for revocation or other action. These proceedings shall be promptly instituted and determined.

4. When the hearing seeks the revocation of a license or permit previously granted by the agency, either party shall, upon demand and at least seven days prior to the hearing, disclose the evidence that the party intends to introduce at the hearing, including documentary evidence and identification of witnesses, provided, however, the provisions of this subdivision shall not be deemed to require the disclosure of information or material otherwise protected by law from disclosure, including information and material protected because of privilege or confidentiality. If, after such disclosure, a party determines to rely upon other witnesses or information, the party shall, as soon as practicable, supplement its disclosure by providing the names of such witnesses or the additional documents.
