In the 1912 parliamentary elections, he ran as a candidate for deputy for Santiago, being elected for the legislative period 1912–1915.^[2] In his tenure, he was an effective collaborator in the Commission of Foreign Relations and Colonization, in the study of projects that he had to sponsor or let pass laws, for example, navigation with Austria; the embassy of the United States; reform of the consular law and others that were of utmost importance.^[2]
