The annotated case concerns an unsuccessful attempt to challenge the Annex to the guidelines, comprising a catalogue of industries eligible for receiving State aid due to the risk of carbon leakage. The appellants’ operations were not included in this list. In its judgment, the Court ruled on the two main pleas: inadequate statement of reasons and error in not considering the applicants as interested parties in a situation where, although no individual Commission’s decision has been issued based on the guidelines yet, the fact of not being included in the Annex prevents them from receiving State aid. The commentary delves into the appellants’ line of reasoning, explaining the attempt to ‘force-fit’ arguments concerning the infringement of law into an issue that falls within the realm of policy. Moreover, the analysis assesses a potential opening left by the Court: challenging individual decisions that authorise aid for other undertakings, evaluating its viability in the context of the most recent developments in case law.
