The previous model had been declared illegal by the European Court of Justice, as it discriminated against the children of residents of neighboring countries working in Luxembourg.

Hansen was member of the parliamentary committees on petitions, agriculture, viticulture, rural development and consumer protection; national education, children and youth; higher education, research, media, communications and space; environment; family and integration; health, equal opportunities and sports, covering only sports on the later.

As leader of the opposition, she became chairwoman of the parliamentary control committee of the State Intelligence Service, and member of the Conférence des Présidents and the Bureau, the two bodies responsible for the organization of Parliament.
