Fusion of powers is a feature of some parliamentary forms of government where different branches of government are intermingled, typically the executive and legislative branches. It is contrasted with the separation of powers found in presidential and semi-presidential forms of government where the legislative and executive powers are in origin separated by popular vote. Fusion of powers exists in many, if not a majority of, parliamentary democracies, and does so by design. However, in all modern democratic polities the judiciary does not posses legislative or executive powers.
