Unified state power

Unified state power is a Marxist–Leninist principle on communist state power that was developed in opposition to the fusion and separation of powers, and creates the institutional framework to practice democratic centralism in the state. It holds that popular sovereignty is expressed through a single representative organ, the supreme state organ of power (SSOP), at the apex of a pyramid-like state structure and which exercises legislative, executive, judicial, and all other forms of state power. Lower-level state organs of power are not autonomous polities but administrative extensions of the SSOP within a single hierarchy. Central decisions bind subordinate levels, while local organs are accountable both to their electors and to superior organs, a system known as dual subordination. This produces a uniform flow of power from the SSOP to subordinate organs, with local discretion allowed only within jurisdiction delegated by higher law enacted by the SSOP.

The SSOP's relationship to the communist state constitution and laws is fundamental. The constitution, adopted by the SSOP, is the fundamental law binding all state organs. It does not permanently restrict the SSOP's sovereign rights, since such limits are self-imposed and may be altered through constitutional amendment. Communist state constitutions set out broad principles on sovereignty and the structure of the state—while leaving specific details to statutes and secondary norms. Socialist legality, the Marxist–Leninist concept of lawful governance, requires conformity to the constitution. However, it rejects independent or autonomous institutions, such as constitutional courts exercising judicial review, that would stand above the SSOP. Instead, legality is safeguarded through political oversight by representative organs, supervision by the supreme procuratorial organ, and electoral accountability through controlled elections.

A key feature is the unity of legislative and executive powers. Drawing on the Paris Commune and the Soviet model, representatives both make law and oversee its execution. The SSOP establishes a division of labour that delineates jurisdictions among the supreme executive and administrative organ (the government), the supreme judicial organ, and other state organs within the unified state apparatus, but this does not create co-equal branches. Each organ operates under the law within an order established by the SSOP, remaining inferior and subordinate to it, and all are overseen by the SSOP with none standing above it. This is reinforced by the leading role of the communist party, which coordinates the unified state apparatus formally through cadre appointments to state positions and party discipline, and informally through party groups embedded in state institutions. The party guides policy while affirming that the state remains the legal locus of sovereignty. Unified power continues to be a cornerstone of governance in the communist states of China, Cuba, Laos, North Korea and Vietnam.
