—

order the Commission to pay the costs.

1.

First plea in law, alleging that Articles 18 to 20 of Annex VIII to the Staff Regulations of Officials of the European Union (‘the Staff Regulations’) are unlawful because they are in breach of the principle of equal treatment and discriminate on the grounds of age, the nature of the legal relationship of a couple’s life together, and disability.

2.

Second plea in law, alleging an error of law in applying Articles 18 and 20 of Annex VIII to the Staff Regulations, in that the Commission should have interpreted those provisions as referring to living together as a married couple, whether the couple is married, in a civil partnership, or cohabiting.

3.

Third plea in law, alleging an error in interpreting the concept of a spouse for the purpose of the system applicable to the survivor’s pension, on the ground that the evolution of Western society calls for a broad interpretation of that concept.

4.

Fourth plea in law, alleging a manifest error of assessment resulting from a failure to take account of the applicant’s individual situation. The applicant argues in that regard, first, that he lived with his wife for more than 19 years and, second, that their marriage lasted 4 years, 7 months and 8 days.
