In Russia, Stalin abolished the soviets (A.K.A worker’s councils, kinda like mega unions) in the Soviet union.
Are you referring to the constitution of 1936, which established 4 layers of representative councils (local, regional, national, union) as Stalin dissolving the Soviets?
why do you think that is worse
why do you blame it on Stalin? Seems like a thing that was written and implemented pretty democratically.
