I thought I had but seemingly had not, flagged Bob Wessels’ timely alert to  COMP 039 Colin King (Supreme Court of Gibraltar). The judgment first of all looks at the temporal scope of application of the Regulation, holding correctly that it is not the filing for bankruptcy which is relevant but rather the time of actual openings of those proceedings. Further, it makes correct application of the various presumptions and definitions vis-a-vis natural persons.
Not a shocking judgment but one which is a good read for a gentle introduction to COMI. And as Bob notes, it was not quite the first to apply the new EIR.
