9E+WWhere an order under section 120 of this Act adds a licensing district or part of a licensing district to a licensing planning area, and the order provides for the appointment of additional members of the licensing planning committee by the licensing justices or a local planning authority having jurisdiction in the added district or part, the order may vary the provisions of the original order constituting the district so as to limit the right of the additional members to vote as members of the licensing planning committee to such matters relating to the added district or part of a district as the order may specify.
