Since 2003, the European Parliament used soft-law self-obligation tools such as resolutions to regulate the implementation of gender mainstreaming through a policy plan in all its policies, in the parliamentary committees, in delegations, and in the administration. The main responsibility for implementing gender mainstreaming was appointed to the Women’s Rights and Gender Equality Committee (FEMM) while the role of the other committees should consist of fulfilling the resolutions in their area of expertise. In this paper I explore how the new EP and its committees comply with self-obligations. The paper rests upon analyzing the set-up of the new EP structures such as the political groups, the bureau, the committees, and the delegations.
