85.—(1) If the Court's opinion is not that mentioned in paragraph 83(1) or 84(1) it must—N.I.
(a)decide whether the difference between the original unit and the new unit is such that the support of the union (or unions) within the new unit needs to be assessed, and
(b)inform the parties of its decision.
(2) If the Court's decision is that such support does not need to be assessed—
(a)the Court must issue a declaration that the union is (or unions are) recognised as entitled to conduct collective bargaining on behalf of the new unit;
(b)so far as it affects workers in the new unit who fall within the original unit, the declaration shall have effect in place of any declaration that the union is (or unions are) recognised as entitled to conduct collective bargaining on behalf of the original unit;
(c)the method of collective bargaining relating to the original unit shall have effect in relation to the new unit, with any modifications which the Court considers necessary to take account of the change of bargaining unit and specifies in the declaration.
