Since 1976, Minnesota has had an independent Office of Administrative Hearings that employs Administrative Law Judges to conduct contested case hearings for other state agencies. ALJs are experienced attorneys who are hired under civil service requirements. The ALJ is responsible for maintaining an orderly proceeding, which is a component of a fair hearing. A number of cases have listed the essential elements of a fair administrative hearing, usually including: the right to be heard; the right to the production of witnesses and documents; the taking of evidence; the examination and cross-examination of witnesses; the right to present argument; and a decision on the merits.
The ALJ is directed by the APA to conduct all hearings in a fair and impartial manner. An agency decision may be vacated and a rehearing required if the ALJ expresses an opinion on the merits during the hearing, comments unfavorably on the evidence of a party, intimidates or discredits witnesses, makes rash statements showing bias, or otherwise exhibits a partisan nature. An administrative order based on a hearing that was so unfair as to deprive a party of the opportunity to fairly present his or her evidence cannot stand. Because the final agency decision must be based on the hearing record, an ALJ has an affirmative responsibility to assure that a full and accurate record is developed at the hearing, especially where a party is unrepresented by counsel. Accordingly, the ALJ must often protect the rights of an unrepresented party by assuring that the party’s case is developed, while at the same time not engaging in advocacy activity on behalf of the unrepresented party. This does not mean, however, that the ALJ is required to assume all the duties of counsel for an unrepresented party, such as the exclusion of objectionable evidence.
