Fascist and conservative sectors of the army plotted openly for a regime change, as did Standard Oil of New Jersey, who opposed both the president's efforts to curb oil smuggling from Salta Province to Bolivia, as well as the existence of YPF itself. On 6 September 1930, Yrigoyen was deposed in a military coup led by General José Félix Uriburu. This was the first military coup since the adoption of the Argentine constitution. After the "coup d'état" Enrique Pérez Colman, Minister of Finance in the Yrigoyen cabinet; General Moscini, former Director of oil fields; General Baldrich and a number of Yrigoyenist deputies were arrested by the provisional government of General Uriburu.
