Gender Identity Law In 2011, Di Tullio introduced a bill that would expand the right to self-determination for transgender people; the bill was drafted with support from the Federación Argentina de Lesbianas, Gays, Bi y Transexuales (FALGBT). Di Tullio's bill was introduced at the same time as two other similar bill projects were introduced in the Chamber, the other two by
Diana Conti (with support from the Comunidad Homosexual Argentina) and by opposition deputies Silvana Giúdici and Miguel Ángel Barrios. The three bills were eventually reformulated into one, which was passed by the Chamber on 30 November 2011.

Argentine Senate in
Buenos Aires Province; the list was headed by
Cristina Fernández de Kirchner and seconded by
Jorge Taiana. Unidad Ciudadana came second in the general election, with 37.31% of the vote. In the electoral system for the upper house, this meant that only Fernández de Kirchner was elected as the senator for the minority. Taiana filled the vacancy left by Fernández de Kirchner being elected
