The petition must be served as required under 220 CMR 1.05(1).(d)Answers to Petitions. A party may file an answer to a petition no later than five days after the petition is filed.(e)Action on Petitions. The Commission, or the presiding officer, shall rule on all such petitions and may grant a person leave to intervene as a party in the whole or any portion of a proceeding or may allow a person who is not a party to make limited appearance by making an oral or written statement of his position on the issue, or by such other participation as the Commission or the presiding officer may determine. Such grant may be conditioned on such terms as the Commission or presiding officer may direct. No grant of such leave to intervene or participate shall be deemed to constitute an expression by the Department that the person allowed to participate is a party in interest, who may be aggrieved by any final decision, order, or ruling, unless the grant explicitly so states.Amended by Mass Register Issue 1315, eff. 6/17/2016.
