Unlike the fixed nature of liberal democratic constitutions, a Marxist–Leninist constitution is ever-changing. Andrey Vyshinsky, a Procurator General of the Soviet Union during the 1930s, notes that the "Soviet constitutions represent the sum total of the historic path along which the Soviet state has traveled. At the same time, they are the legislative basis of subsequent development of state life." That is, the constitution sums up what already has been achieved. This belief is also shared by the Communist Party of China which argued that "the Chinese Constitution blazes a path for China, recording what has been won in China and what is yet to be conquered." A constitution in a communist state has an end. The preamble of the 1954 Chinese constitution outlines the historical tasks of the Chinese communists, "step by step, to bring about the socialist industrialisation of the country and, step by step, to accomplish the socialist transformation of agriculture, handicraft and capitalist industry and commerce."
