(b) An agency shall consider not using a dispute resolution proceeding if
(1) a definitive or authoritative resolution of the matter is required for precedential value, and such a proceeding is not likely to be accepted generally as an authoritative precedent;
(2) the matter involves or may bear upon significant questions of Government policy that require additional procedures before a final resolution may be made, and such a proceeding would not likely serve to develop a recommended policy for the agency;
(3) maintaining established policies is of special importance, so that variations among individual decisions are not increased and such a proceeding would not likely reach consistent results among individual decisions;
(4) the matter significantly affects persons or organizations who are not parties to the proceeding;
(5) a full public record of the proceeding is important, and a dispute resolution proceeding cannot provide such a record; and
(6) the agency must maintain continuing jurisdiction over the matter with authority to alter the disposition of the matter in the light of changed circumstances, and a dispute resolution proceeding would interfere with the agencys fulfilling that requirement.
