Family proceedings – Orders in family proceedings. The court's power pursuant to r 4.1(6) of the Family Procedure Rules 2010, SI 2010/2955, to vary or revoke an order could be appropriately exercised where, among other things, there had been a material change of circumstances. Consequently, having confirmed that he had jurisdiction, the judge exercised that power to vary an earlier order he had made in proceedings under Sch 1 to the Children Act 1989 in circumstances where, since that order had been made, there had been an order in proceedings pursuant to s 8 of that Act that the child should live no longer live with his mother in the UK but with his father in Canada.
