In a decision reached reached this week, the antitrust court found that Apple s UK arm was not responsible for deciding which apps may or may not be supplied through the App Store, so a case against the company could not continue. In my view, that is a significant factor in favour of the US as the appropriate forum, Justice Peter Roth said in his decision. It is clear from even a cursory reading of the judgment of 9 October 2020, and hardly surprising, that many of the same issues of substance which arise under UK competition law arise under US antitrust law.
