In America, AFAIK, if the court wanted to declare that, as the article claims, "Irish law is [not] in compliance with [EU charter] Article 107", it would be forced to strike down the whole law; for example, Brown v.

That the court can declare the law invalid as applied to Apple while retaining it for every other company in Ireland is clearly a violation of the ideal of fair treatment, if not the rule of law in the first place.
