The General Court's decision in Apple’s Irish tax case confirmed that the European Commission is competent to review national tax rulings for whether they confer a selective advantage on a tax payer. Further, the GCEU validated the legal tests on which the Commission relied in reaching its State aid decision. However, the GCEU found that the Commission had failed in its assessment of the specific facts of this case and in particular failed to show the existence of a selective advantage. It therefore annulled the Commission’s decision. Given that the GCEU ruled in favour of the Commission on virtually all points of law but censured the Commission on questions of fact, the Commission’s appeal to the CJEU is likely to face significant challenges on both admissibility and substance.
