While the three islands are considered to be land of the Netherlands, they are not a part of the European Union, therefore not subject to European Union Law. They are considered to be an overseas country and territory. Bonaire's non-governmental organization, Nos Ke Boneiru Bèk ("We Want Bonaire Back"), is against the current constitutional relationship with the Netherlands. With reference to Bonaire's 2004 referendum, the organization is of the opinion that such an arrangement was never the choice of the people. The Dutch Minister of Home Affairs and Kingdom Relations, Ronald Plasterk, replied to the organization confirming that only the "Island Councils in the Caribbean Netherlands have the authority to decide on holding a constitutional referendum, not the Dutch government." In response, the organization gathered more than 3,500 signatures in 2013 favouring a new referendum.

Plasterk responded by advising Finies that preparations for the evaluation of the public entity structure had begun for 2015, but a "possible change of the constitutional relations is not part of that evaluation". The new referendum took place on 18 December 2015. 65% of the turnout voted that they were not happy with the current relationship between Bonaire and the Netherlands. Geography Bonaire lies about off the coast of Venezuela on the continental shelf of South America, and is thus geologically considered a part of the continent. Geologists believe that Bonaire was formed relatively recently. As the nearby continental shelf (now located near Montserrat, and the cause of the volcanic activity on that island) moved through the area, it forced a large mass of rock to the ocean surface and created the islands of the Lesser and Greater Antilles, including Bonaire. As the seabed rose a vast coral reef grew on what is now dry land. These corals were eventually exposed to air and perished, becoming surface limestone deposits over the millennia. Vast amounts of coral skeletons may be seen along the shoreline and across the interior of Bonaire. The island is essentially
