84As regards the applicant’s argument that there is already a debate about the additional pension scheme, given the controversy about its creation and funding, or that, even without such a debate, it would be necessary to have the MEPs’ names in order to encourage a debate to arise, the applicant is merely relying on arguments that relate to the purpose of his application for access to documents. Those arguments do not establish that it is necessary for him to have the data at issue transferred, no link to the appropriateness or proportionality of the measure requested being apparent, as required by EU case-law (see, to that effect, judgment in Dennekamp v Parliament, cited in paragraph 4 above, EU:T:2011:688, paragraph 34). In addition, the existence of a debate about the scheme, or, more specifically, about the advantageous nature of the scheme for MEPs at the expense of public funds tend, like the various matters of fact alluded to by the applicant, to show that he already has precise information on the rules and operation of the scheme that may enable him to encourage or develop the public debate he seeks to initiate with regard to the sound management of the scheme and to the financial risks to the EU budget. In addition to the absence of proof of the necessity of the transfer of the personal data at issue, it must be noted that those various matters put forward by the applicant himself do not militate in favour of the proposition that it would be necessary to know the names of the MEPs participating in the scheme in order to denounce its allegedly adverse effects on public funds.
