By the decision at issue, the Secretary-General of the Parliament considered that a sum of EUR 78 838.21 had been unduly borne by that institution in connection with the use of A for the period from 22 May 2015 to 22 November 2016 and that it should be recovered from TC pursuant to Article 68(1) of the Implementing Measures. On 31 March 2021, the Director-General for Finance, in his capacity as authorising officer by delegation, therefore issued the debit note, ordering the recovery of that sum from TC and requesting him to pay the sum by 30 May 2021 at the latest. On 31 March 2021, the Director-General for Finance notified TC of the decision at issue and the debit note. The action before the General Court and the judgment under appeal 34 By application lodged at the Registry of the General Court on 24 May 2021, TC brought an action for annulment of the decision at issue and the debit note. In support of that action, he relied on five pleas in law.
