Sch 4 para 4
(1) In this paragraph an “existing order” means any order under Article 18 or 21 of the Order of 1980 or Article 4 or 13 of the Order of 1984 which— (a) is in force immediately before the commencement of the repeal of that Article; or (b) was made or granted after that commencement in proceedings brought before that commencement. (2) Subject to sub-paragraphs (3) and (4), nothing in this Order prevents an existing order from remaining in force or affects the enforcement of such an order. (3) Nothing in this Order affects any application to vary or discharge an existing order, but the court may, if it thinks it is just and reasonable to do so, treat the application as an application for an order under this Order. (4) The making of an order under this Order between parties with respect to whom an existing order is in force discharges the existing order.
