150. Before being sent to the parties, awards may be scrutinised by ACAS to check for clerical or computational mistakes, errors arising from accidental slips or omissions, ambiguities, or errors of form. Without affecting the arbitrator’s liberty of decision, ACAS may refer the award back to the arbitrator (under the provisions below) in order to draw his or her attention to any such point.
151. The arbitrator may, on his or her own initiative or on the application of a party or ACAS:
(i)correct the award so as to remove any clerical or computational mistake, or error arising from an accidental slip or omission, or to clarify or remove any ambiguity in the award, or
(ii)make an additional award in respect of any part of the claim which was presented to the arbitrator but was not dealt with in the award.
152. In so far as any such correction or additional award involves a new issue that was not previously before the parties, this power shall not be exercised without first affording the parties a reasonable opportunity to make written representations to the arbitrator.
153. Any application by a party for the exercise of this power must be made via the ACAS Arbitration Section within 28 days of the date the award was despatched to the applying party by ACAS.
154. Any correction of the award shall be made within 28 days of the date the application was received by the arbitrator or, where the correction is made by the arbitrator on his or her own initiative, within 28 days of the date of the award.
155. Any additional award shall be made within 56 days of the date of the original award.
156. Any correction of the award shall form part of the award.
