The Board may continue the hearing to a new date for additional testimony. All scheduled submissions from all parties must be delivered to and stamped in at the Board office with the requisite number of copies. Upon motion of the Chair or any commissioner, the Board may vote to close the hearing and to permit no further testimony. In appropriate cases, the Chair may permit the record to remain open until a given date for submissions of written evidence. The Chair may also permit technical and other minor revisions to be accepted after the hearing is closed but before the vote. Factors the Board will consider in determining whether the revision is technical or minor include: whether the revision would have any material impact on the Board's findings, whether the revisions were discussed at a public session by the Board, or whether the revision is essentially an administrative correction.
