During his 2019–2023 term, Igon formed part of the parliamentary commissions on Human Rights and Guarantees, Energy and Fuels, Labour Legislation, Mining, Internal Security, Addiction Prevention, and Maritime Interests (the latter two of which he served in as secretary).[1] He was a supporter of the legalisation of abortion in Argentina, voting in favour of the two Voluntary Interruption of Pregnancy bills debated by the Argentine Congress in 2018 and 2020, the last of which passed the Chamber and became law in 2021.[5][6]
