Austria's federal constitution defines Austria to be a presidential democracy: the executive branch of government is supposed to be headed by the president and not to be answerable to the legislative branch. In practice, however, Austria's federal administration as such has comparatively little scope and would be almost totally paralyzed should the National Council fail to support it. While the executive branch has the theoretical authority to dissolve a hostile National Council, constitutional convention prevents this power from being exercised. Austria accordingly functions as a parliamentary democracy: for all intents and purposes, the cabinet is subject to approval by the National Council, the president being little more than a figurehead.
