A revision in 1848 instituted a system of parliamentary democracy. In 1983, a major revision of the Constitution of the Netherlands was undertaken, almost fully rewriting the text and adding new civil rights. The text is sober, devoid of legal or political doctrine and includes a bill of rights. It prohibits the judiciary to test laws and treaties against the constitution, as this is considered a prerogative of the legislature. There is no constitutional court in the Netherlands, except for the Constitutional Court of Sint Maarten which only governs the Sint Maarten legislature. The Kingdom of the Netherlands also includes Aruba, Curaçao and Sint Maarten: there is an overarching instrument of the entire kingdom that has constitution characterisics: the Statute of the Kingdom of the Netherlands.
