Noble was a vocal advocate for the overthrow of President Yrigoyen, whose high-handed style of governing put him in a precarious situation following the Wall Street Crash of 1929. The regime that deposed the aging Yrigoyen in a coup in September, 1930, gave way to elections the following year, for which the new regime organized the Concordance, a coalition of the National Autonomist Party (the conservative party in power during most of the 1880-1916 era) with centrist Radical Civic Union figures opposed to Yrigoyen and amenable Socialists. Having been part of the latter group since 1927, Noble joined the ticket and was elected to the Chamber of Deputies (lower house of congress). Representing the city of Buenos Aires until 1936, he introduced a number of progressive bills that became law, including needed anti-abuse reforms to rural Argentina's Justice of the Peace system and the landmark Law 11723, the basis for Argentina's Law of Intellectual and Artistic Property.
