19Following an ex post financial audit, ERCEA concluded that staff costs in the amount of EUR 245 525.43 were ineligible and decided to claim reimbursement of that sum from Aristotle University, issuing a debit note to that end. Aristotle University challenged the validity of that debit note before the General Court. By judgment of 17 January 2019, Aristoteleio Panepistimio Thessalonikis v ERCEA (T‑348/16 OP, EU:T:2019:14), the General Court held that the claim formulated in the ERCEA debit note, seeking reimbursement from that university of an amount of EUR 245 525.43, was unfounded up to an amount of EUR 233 611.75 corresponding to eligible costs. That judgment was subsequently upheld by the Court, on appeal, in the judgment of 14 January 2021, ERCEA v Aristoteleio Panepistimio Thessalonikis (C‑280/19 P, EU:C:2021:23).
