Minn. Stat. § 14.61

§ Subdivision 1. Filing of exceptions. In all contested cases the decision of the officials of the agency who are to render the final decision shall not be made until the report of the administrative law judge as required by sections 14.48 to 14.56 , has been made available to parties to the proceeding for at least ten days and an opportunity has been afforded to each party adversely affected to file exceptions and present argument to a majority of the officials who are to render the decision. This section does not apply to a contested case under which the report or order of the administrative law judge constitutes the final decision in the case.

§ Subd. 2. Closure of record.

The agency shall notify the parties and the presiding administrative law judge of the date when the hearing record closed. In all contested cases where the report or order of the administrative law judge constitutes the final decision in the case, the hearing record must close as ordered in writing by the presiding administrative law judge.
