Every rule proposed by any administrative agency must be submitted to the attorney general for an opinion as to its legality before final adoption, and the attorney general promptly shall furnish each such opinion. The attorney general may not approve any rule as to legality when the rule exceeds the statutory authority of the agency or is written in a manner that is not concise or easily understandable or when the procedural requirements for adoption of the rule in this chapter are not substantially met. The attorney general shall advise an agency of any revision or rewording of a rule necessary to correct objections as to legality.
