After the Tsar had been dethroned, the Finnish Parliament had to decide whether the highest authority in the country had passed on to the Russian Provisional Government, the Finnish Parliament or the Finnish Senate. The question led to serious strife between the right-wing and the left-wing elements of the Parliament. Kallio initially supported the socialists in demanding said power to the Parliament, but disapproved of their cooperation with Russian Bolsheviks and Mensheviks, and ultimately voted against the bill they had drafted. Nonetheless, the socialist proposal passed, which the Russian Provisional Government saw as an affront to their power, and Alexander Kerensky consequently dissolved the Parliament on September 8. Kallio and the Socialist Senators resigned from the Senate, which continued to operate under the leadership of E. N. Setälä.
