 With Moscovici, Șerban Voinea, and Iacob Pistiner, Flueraș represented the PSD to the 1924 Congress of the Labor and Socialist International in Marseille.When the authoritarian regime of King Carol II was imposed in 1938, he supported the change and remained active in the guilds established by the new corporatist structure of the National Renaissance Front (as a member of the Upper Economic Council and the Senate).A potential target of Iron Guard reprisals during the National Legionary State, Flueraș survived the Legionnaires' Rebellion, and, upon the Guard's defeat, sent a congratulatory telegram to "Conducător" Ion Antonescu.
