Background - what was the application and why was it needed?

The UK's Supreme Court ("UKSC") has handed down its judgment following the hearing of the appeal in the case of Sevilleja v Marex Financial Limited [2020] UKSC 31 ("Marex"). The appeal was against the decision of the Court of Appeal to find that the rule of reflective loss applied to 90% of Marex's claim, which was brought in its capacity as a creditor.

The appeal was unanimously allowed by UKSC and it confirmed the rule did not extend to creditors.
