L v M (R and another intervening) (Case C-656/13) EU:C:2014:2364; [2014] WLR (D) 480
‘Article 12(3) of Council Regulation (EC) No 2201/2003 allowed, for the purposes of proceedings in matters of parental responsibility, the jurisdiction of a court of a member state which was not that of the child’s habitual residence to be established even where no other proceedings were pending before the court chosen. Article 12(3)(b) meant that it could not be considered that the jurisdiction of the court seised by one party of proceedings in matters of parental responsibility had been “accepted expressly or otherwise in an unequivocal manner by all the parties to the proceedings” where the defendant in those proceedings subsequently brought a second set of proceedings before the same court and, on taking the first step required of him in the first proceedings, pleaded the lack of jurisdiction of that court.’
