The Defendant unsuccessfully challenged the jurisdiction of the English Court. The Commercial Court decision was subsequently appealed to the Court of Appeal and, then, the Supreme Court. All seven justices of the Supreme Court ruled in favour of our client in a judgment described as “one of the most important company and commercial law decisions of the last thirty years” overturns the long standing approach to the “reflective loss” rule (The Times).
