The categories of law distinguish between National Legislation and Devolved Units' Legislation. National/federal governments enact national/federal legislation is legislation that is applicable in the entire country. Devolved units of government are units of government that are separate and distinct from national/federal governments. Because they are lesser units of government, national/federal laws give them the power to enact legislation. As a result, the laws they enact only apply to certain thematic areas that the national government has devolved to them to govern, oversee and enforce. Examples of devolved units of government include provinces, regions, states, counties and other local government units.
