Minn. Stat. § 14.08
(a) One copy of a rule adopted under section 14.26 must be submitted by the agency to the chief administrative law judge. The chief administrative law judge shall request from the revisor certified copies of the rule when it is submitted by the agency under section 14.26. Within five working days after the request for certification of the rule is received by the revisor, the revisor shall either return the rule with a certificate of approval of the form of the rule to the chief administrative law judge or notify the chief administrative law judge and the agency that the form of the rule will not be approved.
If the chief administrative law judge disapproves a rule, the agency may modify it and the agency shall submit one copy of the modified rule, approved as to form by the revisor, to the chief administrative law judge.
