In  EWHC 960 (Ch) New Look Secured Issuer and New Look Ltd, Smith J at H applies the standing rules on jurisdiction over the scheme and other companies which I also signalled in Algeco and Apcoa (with further reference in the latter post). Against the scheme companies jurisdiction is straightforward: they are England incorporated. Against the scheme creditors, English courts apply the jurisdictional test viz the Brussels I Recast (‘a’) Regulation arguendo: if it were to apply (which the English Courts have taken no definitive stance on), would an English court have jurisdiction? Yes, it is held: under Article 8 (anchor defendants). (Often Article 25 is used as argument, too).
At 48 Smith J signals the ‘intensity’ issue: ‘In some cases it has been suggested that it may not be enough to identify a single creditor domiciled in the United Kingdom, and that the court should consider whether the number and size of creditors in the UK are sufficiently large: see Re Van Gansewinkel Groep,  EWHC 2151 (Ch) at ); Global Garden Products at ; Re Noble Group Ltd  EWHC 3092 (Ch) at  to .’ Smith J is minded towards the first, more liberal approach: at 49. He refers to the liberal anchoring approach in competition cases, both stand-alone (think Media Saturn) and follow-on (think Posten /Bring v Volvo, with relevant links there).
At 51 he also discusses the ‘substantial effects’ test and classifies it under ‘jurisdiction’:
‘As well as showing a sufficient jurisdictional connection with England, it is also necessary to show that the Schemes, if approved, will be likely to have a substantial effect in any foreign jurisdictions involved in or engaged by the Schemes. This is because the court will generally not make any order which has no substantial effect and, before the court will sanction a scheme, it will need to be satisfied that the scheme will achieve its purpose: Sompo Japan Insurance Inc v Transfercom Ltd,  EWHC 146 (Ch); Re Rodenstock GmbH,  EWHC 1104 (Ch) at -; Re Magyar Telecom BV,  EWHC 3800 (Ch) at .’
This is not quite kosher I believe. If, even arguendo, jurisdiction is established under Brussels Ia, then no ‘substantial effects’ test must apply at the jurisdictional stage. Certainly not vis-a-vis the scheme companies. Against the scheme creditors, one may perhaps classify it is a means to test the ‘abuse’ prohibition in Article 8(1)’s anchor mechanism.
A useful reminder of the principles. And some doubt re the substantial effects test.
