131Thirdly, although the composition of the two amounts corresponding to Mr Alberto Spagnolli’s ‘net salaries’ is part of the fictive incomes (amount A) indicated in Notice No 3, being the amount equal to EUR 7 722.61 and the amount equal to EUR 8 084.74, does not appear in Notice No 3, the decision rejecting the complaint of 4 March 2016 or in the Commission’s statement in defence, such an omission, in both Notice No 3 and the other notices, did not prevent the applicants from understanding and therefore challenging, within the time limit, that is to say, in the action for annulment of Notice No 3 in Case T‑568/16, the method of calculation applied by the Commission, consisting of cumulating the salary of the surviving spouse and that of the deceased spouse. Both the adoption of the decision to recover undue payments and the communication of the details of the calculations of the fictive salaries indicated in the different notices cannot be held to be new facts allowing the applicants, who omitted to avail themselves in due time of the remedies available to them to challenge an act adversely affecting them, to put forward new grounds of annulment of Notice No 3, thereby circumventing the time limit for bringing an action against that notice.
