This judgement was pronounced by the London High Court not by the “UK’s top court” which is the UK’s supreme court.
And no, the ECJ does not even entertain such ideas as yours — It is not possible to appeal against the decisions of national courts in the ECJ, but rather national courts refer questions of EU law to the ECJ. However, it is ultimately for the national court to apply the resulting interpretation to the facts of any given case.
Seems I’ve heard where the UK ruling on something is appealed to a higher authority outside the UK and that, by itself, proves the UK can be “ruled” by Europeans, not Brits.
