The Court sets aside the judgment of the General Court of the European Union in Greece and Ellinikos Chrysos v Commission (T‑233/11 and T‑262/11, EU:T:2015:948) in so far as, by that judgment, the General Court failed to respond to Ellinikos Chrysos AE Metalleion kai Viomichanias Chrysou's argument based on the purpose for which the expert report on the appraisal of the mines in Cassandra (Greece) had been drawn up during 2004. The Court dismisses the appeal as to the remainder.
