Notes:

The Gender Parity in Political Representation Act (Ley 27.412) stipulates what is known as a zebra system for the lists of candidates to the Chamber of Deputies, the Senate and the Mercosur Parliament. The lists must alternate between men and women candidates from start to finish for both titular and substitute candidates. Lists that do not comply with this requirement will not be validated.

The Organic Act on Political Parties (Ley 23.298) further stipulates that, in cases where the principle of gender parity is breached, political parties may lose their political and legal personality.

Sources: Article 60 bis of the National Electoral Code (Código Electoral Nacional) and article 50 (h) of the Organic Act on Political Parties (Ley 23.298) as amended by the Gender Parity in Political Representation Act (Ley 27.412). The latter Act was adopted by the Chamber of Deputies on 22 November 2017, enacted by the President of the Republic (Decreto No. 1035) on 14 December 2017, and published in the official journal (BORA) on 15 December 2017.
