 But in July, a Moscow congress of Ukrainian Bolsheviks rescinded the resolution, and the Ukrainian party was declared a part of the Russian Communist Party.Skrypnyk worked for the Cheka secret police during the winter of 1918–19, then returned to Ukraine as People's Commissar of Worker-Peasant Inspection (1920–21), and Internal Affairs (1921–22).During debates leading up to the formation of the Soviet Union in late 1922, Skrypnyk was a proponent of independent national republics, and denounced the proposal of the new General Secretary, Joseph Stalin, to absorb them into a single Russian SFSR state as thinly-disguised Russian chauvinism.Lenin temporarily swayed the decision in favour of the republics, but after his death, the Soviet Union's constitution was finalized in January 1924 with very little political autonomy for the republics.
