12 December 1980
In application of Article 24 in connection with Article 15 of the Convention the Kingdom makes the reservation that its authorities shall apply its internal law if the creditor and the debtor are both nationals of the Kingdom of the Netherlands and if the debtor has his habitual residence in the Kingdom.
The Kingdom of the Netherlands consisted of three parts: the Netherlands, the Netherlands Antilles and Aruba. The Netherlands Antilles consisted of the islands of Curaçao, Sint Maarten, Bonaire, Sint Eustatius and Saba. With effect from 10 October 2010, the Netherlands Antilles ceased to exist as a part of the Kingdom of the Netherlands. Since that date, the Kingdom consists of four parts: the Netherlands, Aruba, Curaçao and Slnt Maarten. Curaçao and Sint Maarten enjoy internal self-government within the Kingdom, as Aruba and, up to 10 October 2010, the Netherlands Antilles do. These changes constitute a modification of the internal constitutional relations within the Kingdom of the Netherlands. The Kingdom of the Netherlands will accordingly remain the subject of international law with which agreements are concluded. The modification of the structure of the Kingdom will therefore not affect the validity of the international agreements ratified by the Kingdom for the Netherlands Antilles. These agreements, including any reservations made, will continue to apply to Curaçao and Sint Maarten. The other islands that have formed part of the Netherlands Antilles - Bonaire, Sint Eustatius and Saba - became part of the Netherlands, thus constituting "the Caribbean part of the Netherlands". The agreements that applied to the Netherlands Antilles will also continue to apply to these islands; however, the Government of the Netherlands will now be responsible for implementing these agreements.
The reservation [of 12 December 1980] is confirmed for Curaçao, Sint Maarten and the Caribbean part of the Netherlands (the islands of Bonaire, Sint Eustatius and Saba). The reservation remains valid for the European part of the Netherlands and Aruba.
