Grounds of appeal and main arguments

The appellant raises a single ground of appeal:

According to the appellant, the General Court misinterpreted and misapplied Article 107(1) TFEU, because it considered that the Commission could not have ruled out the existence of an advantage on the basis of application of the market economy operator test in relation to DEI’s recourse to arbitration with Mytilinaios, but should have examined whether the tariff determined by the arbitration tribunal in fact reflected the market price, because the arbitration tribunal should supposedly have been treated in the same way as an ordinary State court.

Owing to that error of law, the General Court erred in finding that the Commission should have entertained doubts within the meaning of Article 4(4) of Regulation 2015/1589, (1) on the basis of which it should have opened a formal investigation procedure under Article 108(2) TFEU regarding the tariff fixed by the arbitration tribunal.
