An enabling act is a piece of legislation by which a legislative body grants an entity which depends on it for authorization or legitimacy of power to take certain actions. For example, enabling acts often establish government agencies to carry out specific government policies in a modern nation. The effects of enabling acts from different times and places vary widely.
