87.—(1) Subject to Article 86(5), a person constructing or proposing to construct a water main or service pipe may appeal to the Authority where the water undertaker—
(a)has refused an application under Article 86;
(b)has offered to grant such an application on terms to which that person objects; or
(c)has failed, before the end of two months from the making of such an application, either to refuse the application or to give notice to the applicant of the terms on which it is prepared to grant the application.
(2) On the hearing of an appeal under this Article, the Authority may—
(a)uphold the refusal of the undertaker to grant the application or to modify the terms offered; or
(b)on behalf of the undertaker, refuse the application or enter into any agreement into which the undertaker might have entered on the application.
(3) Where the Authority makes an agreement under paragraph (2)(b) on behalf of a water undertaker, it may do so on such terms as it considers reasonable or, as the case may be, on the terms offered by the undertaker subject to such modifications as it considers appropriate for ensuring that the terms of the agreement are reasonable.
(4) An agreement entered into on behalf of a water undertaker under paragraph (2)(b) shall be deemed, for the purposes of this Order, to have been entered into under Article 86.
(5) In deciding on an appeal under this Article, the Authority may include such incidental, supplemental and consequential provision (including provision requiring either party to pay a sum in respect of the costs or expenses incurred by the Authority) as it thinks fit, and any such provision as to costs or expenses shall be enforceable as if it were a money judgment within the meaning of the Judgments (Enforcement) (Northern Ireland) Order 1981(NI 6).
