A constitution is the rulebook that every other law has to obey — it says who may exercise power, how, and where that power stops. This category works through constitutional law the way it is taught the world over, staying with the general principles rather than the quirks of any one country. Start with the basics: what a constitution is, how power is split between the branches of government, and what the rule of law demands. Level up to the rights and liberties a constitution guarantees against the state. Then finish with the machinery that keeps it all honest — judicial review, the supremacy of the constitution over ordinary statutes, and the ways a constitution is amended.
