The Presiding Officer may issue, vacate, modify and enforce subpoenas requiring the attendance and testimony of witnesses and/or the production of documents or other evidence in accordance with the following provisions.
A subpoena may be issued in the name of the Authority by the Presiding Officer, for purposes of providing testimony or evidence at any hearing, only upon motion to all Parties and, as applicable, to any proposed non-party witness. The motion shall demonstrate, with particularity, the need for the particular witnesses' testimony, the connection between the witnesses' personal knowledge and the factual disputes in the proceeding, the reason that the evidence cannot be adduced through stipulation or through other witnesses more competent and/or percipient than the person as to whom a subpoena is sought, and such other information as will assist the Presiding Officer in a determination that the evidence sought to be adduced through the witness will not be unduly duplicative of other evidentiary sources not requiring subpoenaed testimony, and that the subpoena is not sought for purposes of harassment or oppression.
A subpoena, whether for purposes of discovery or a hearing, shall be subject to such terms and scope as the Presiding Officer may deem appropriate. Every subpoena shall show on its face the name and address of the requesting Party. The Authority may prescribe the form of subpoena but, insofar as practicable, such form shall adhere to the form used in civil cases before the state courts of Massachusetts.
