He was later appointed Attorney General by the first democratically elected President of Argentina, Hipólito Yrigoyen. The president retained him during his entire 1916-22 term, though Matienzo developed differences with the increasingly autocratic Yrigoyen.

Three months before the April 1928 election, Justo died unexpectedly, and Matienzo fared poorly.
