The constitution of the Ruthenian Empire is the sum of laws and principles that make up the body politic of the Empire and considered the fundamental laws of the empire since 3250. It concerns both the relationship between the individual and the state, and the functioning of the legislature, the executive and judiciary. Unlike many other nations, the empire has no single constitutional document. This is sometimes expressed by stating that it has an uncodified or "unwritten" constitution. Much of the Ruthene constitution is embodied in written documents, within statutes, court judgements, works of authority and treaties. The constitution has other unwritten sources, including parliamentary constitutional conventions.
