Notable Cases
Des Pallieres v Des Pallieres [2021] 4 WLR 96 (Court of Appeal)
DP v DP [2020] EWHC 3188 (Fam) (High Court)
The appeal concerned an application made for registration of a French order made (in error) under BIIA which governs parental responsibility when the wife’s intention was to issue enforcement proceedings for maintenance. For three years neither party realised this error or the court’s lack of jurisdiction. Upon it being noted the wife applied for the court to rectify the error and substitute registration for that under the Maintenance Regulation under FPR 4.1(6). The husband opposed the application on the basis that the court did not have jurisdiction under r.4.1(6) to do what was being proposed and that all orders made for enforcement of maintenance were thus void.
M v P (the Queen's Proctor Intervening) [2019] 2 FLR 813
Highly publicised case before Sir James Munby led by Janet Bazley QC opposing an application by the Queen's Proctor to strike out (on the basis of it being void) the decree of divorce in circumstances where the petitioner initially by mistake relied upon the wrong facts in his petition, the court having missed the error then granted decrees nisi and absolute. The parties remarried before the error was identified by the court.
Mills v Mills [2018] 4 All ER 612 [2018] UKSC 38
Appeal before the Supreme Court which was highly publicised. This appeal was from the Court of Appeal's decision in circumstances where the ex-wife had received a lump sum in the financial proceedings to allow her to rehouse and had depleted all of this capital. Led by Frank Feehan QC.
The Court of Appeal had allowed the ex-wife's appeal and increased her maintenance order to include all of her rent. The Supreme Court found that the judge at first instance had justified the maintenance award made and why there be no further increase to include her full rental costs on the basis of her financial mismanagement.
Mills v Mills [2017] EWCA Civ 129
Appeal by the ex-wife from decision of the judge at first instance on application to vary the maintenance order under s. 31 of the MCA in respect of a joint lives maintenance order. Led by Frank Feehan QC. The ex-husband applied to discharge the maintenance order and the ex-wife applied to increase the quantum to include her full rental costs. Neither application was granted at first instance. The Court of Appeal increased the maintenance level to include all of the ex-wife's rental costs.
Application for retrospective leave to remove the children from the jurisdiction in circumstances where the mother had abducted them and return orders had been made which she breached. The circumstances had now changed as the children had now been living abroad for a number of years and were settled.
LM and DR (Return to Non-Convention Country) [2016] EWHC 1943 (Fam)
Abduction case before MacDonald J under the inherent jurisdiction led by Richard Harrison QC. The father had abducted the child, obtained a prohibited steps order and opposed the child's return. Application for return to Azerbaijan granted.
Leading James Chegwidden before Mrs Justice Roberts, this was the father's application for the children to be circumcised (on non-medical grounds) and for permission to take them on holiday to France and to Algeria. These applications were refused.
In the Matter of JL and AO (Babies Relinquished for Adoption) [2016] 4 WLR 40; [2017] 1 FLR 1545
One of two cases before Baker J (as was) where the parents were not English but were working in this jurisdiction and had requested that their baby be adopted in England. Led by Frank Feehan QC. The issues included whether their greater family in their country of origin be informed of the situation (contrary to their wishes), whether the baby be sent to their country of origin where further decisions be made and whether care orders be made. Baker J gave leading guidance.
Guerroudj v Rymarczyk [2016] 1 FLR 1349
This was an appeal in the Court of Appeal in respect of a transfer of tenancy case under Part VI of the Family Law Act 1996. The appeal was in respect of the judge's decision to set aside a previous order transferring the tenancy to him and then transferring the tenancy instead to his ex-girlfriend given his back problems and her assertions that the local authority were likely to rehouse him and not her given his disabilities.
