The Constitution of the Netherlands Antilles (Dutch: Staatsregeling van de Nederlandse Antillen) was proclaimed on 29 March 1955 by Order-in-Council for the Kingdom.
Its proclamation was specifically mandated by article 59(4) of the Charter for the Kingdom of the Netherlands, which had been enacted on 15 December 1954.
The region is still part of the Kingdom of the Netherlands and hence has no autonomy over issues including defence, foreign policy, citizenship and extradition.
The Netherlands Antilles consists of five islands: Bonaire, Curaçao, Saba, St. Eustatius and St. Maarten.
On that date, Bonaire, Saba and St. Eustatius continued as so called 'gemeentes', which means that they became part of the country of the Netherlands.
