Constitution of the Soviet Union
Claiming themselves to be at a "lower stage of communism" (i.e. "socialism", in line with Vladimir Lenin’s terminology), the Soviet Union adapted the formula as: "From each according to his ability, to each according to his work (labour investment)". This was incorporated in Article 12 of the 1936 Constitution of the Soviet Union, but described by Leon Trotsky as "This inwardly contradictory, not to say nonsensical, formula".
