He went underground and the SR Central Committee sent him to the Volga region and to the Urals to attend the State Meeting in Ufa and organize an uprising against the Bolsheviks.

After Alexander Kolchak's coup on 18 November 1918, Vol'skii issued an appeal "To all the peoples of Russia," in which he announced the election of a Committee, responsible for the Congress of the All-Russian Constituent Assembly.

The SR Central Committee reacted negatively to the idea of negotiations and labelled the actions of the Ufa delegation as a betrayal of the party.

At the end of October, the SR Central Committee decided to dissolve the People's group, and its leaders received a final warning with the threat of expulsion from the party.

Other members of the Central Bank proposed to expel Vol'skii from the MPSR and conduct a party investigation in the case of the Political Center.

In March 1922, the GPU exposed the Political Center and other material from the state's investigation of the party, seized during a year of searches and arrests.
