The Charter for the Kingdom of the Netherlands (in Dutch: Statuut voor het Koninkrijk der Nederlanden; in Papiamentu: Statuut pa e Reino di Hulanda) describes the political relationship between the four countries that constitute the Kingdom of the Netherlands: Aruba, Curaçao, and Sint Maarten in the Caribbean and the Netherlands (for the most part) in Europe. It is the leading legal document of the Kingdom. The Constitution of the Netherlands and the Basic Laws of the three other countries are legally subordinate to the Charter. The first version of the Charter, which described the relationship between the Netherlands, Suriname, and the Netherlands Antilles, was signed by Queen Juliana on 15 December 1954.
The four countries mentioned in the Charter are the Netherlands, Aruba, Curaçao, and Sint Maarten. The Charter stipulates that the Netherlands is governed according to the provisions of the Constitution for the Kingdom of the Netherlands and that Aruba, Curaçao and Sint Maarten are governed according to their respective Basic Laws.
Until 1954 the Constitution for the Kingdom of the Netherlands was the leading document of the Kingdom. It remains, however, the document in which, according to Article 5 of the Charter, the institutions of the Kingdom are regulated. These institutions, as regulated in the Constitution for the Kingdom of the Netherlands, govern the Netherlands proper. The Charter itself gives additional regulations for these institutions for the purposes of the Kingdom as a whole. The Netherlands is the only one of the four countries which conducts its business internally and externally as the Kingdom of the Netherlands.
