(e) A proposed decision in an administrative hearing shall be in a form that may be adopted as the final decision by the agency with authority to make the final decision. The proposed decision is a public record, except as otherwise provided by statute. A copy of the proposed decision shall be served by the office on each party in the case or on the attorneys representing those parties in the hearing. Unless the office has established a shorter time period or another statute has established a different time period, within 30 days after the proposed decision is served, a party may file with the agency a proposal for action under (1) — (5) of this subsection. The agency with authority to make a final decision in the case retains agency discretion in the final disposition of the case and shall, within 45 days after the date the proposed decision is served or at the next regularly scheduled meeting that occurs at least 45 days after the proposed decision is served, do one or more of the following:
- (1) adopt the proposed decision as the final agency decision;
- (2) return the case to the administrative law judge to take additional evidence or make additional findings or for other specific proceedings, in which case the administrative law judge shall complete the additional work and return the revised proposed decision to the agency within 45 days after the original decision was returned under this paragraph;
- (3) exercise its discretion by revising the proposed enforcement action, determination of best interests, order, award, remedy, sanction, penalty, or other disposition of the case, and adopt the proposed decision as revised;
- (4) in writing, reject, modify, or amend a factual finding in the proposed decision by specifying the affected finding and identifying the testimony and other evidence relied on by the agency for the rejection, modification, or amendment of the finding, and issue a final agency decision;
- (5) in writing, reject, modify, or amend an interpretation or application in the proposed decision of a statute or regulation directly governing the agency's actions by specifying the reasons for the rejection, modification, or amendment, and issue a final agency decision.
