a conference was held by the governments of the Netherlands, Aruba and the Netherlands Antilles to discuss future constitutional reform and the dissolution of the Netherlands Antilles. In 2006, Sint Maarten and Curaçao chose autonomy, and Bonaire, St. Eustatius and Saba opted for a closer relationship with the Netherlands. Constitutional referendums and dismantlement of the Netherlands Antilles was scheduled to take place in 2010. Bonaire's announced referendum scheduled for 26 March 2010 was canceled in February 2010. The governor of the Dutch Antilles, Frits Goedgedrag, decided to cancel it because it probably contravened international law since part of the population was barred from voting. European Dutch nationals were only allowed to vote if they arrived on the island before 1 January 2007. The referendum was postponed to September and then October 2010. Eventually the referendum was held on 17 December 2010, with 84% voting in favor of becoming part of the Netherlands. However, as the 35% voter turnout rate was below the required 51%, the results of the referendum were declared invalid. Judicial Institution and Prison The Judicial Institution (JI) of the Dutch Caribbean (Justitiële Inrichting Caribisch Nederland), based on Bonaire, is located in Kralendijk. Since 10 October 2010, the centre has been under the responsibility of the Department of Judicial Institutions (DJI), the agency of the Dutch Ministry of Justice and Security for the execution of sentences and custodial measures. The Bonaire site is both a House of Detention and a Judicial Institution. Since 6 December 2010 there is capacity for 76 men, women and juveniles. The name in Papiamento is Institushon Hudisial Karibe Hulandes, Boneiru site. Economy Tourism Bonaire's economy is mainly based on tourism, taking advantage of its warm, dry climate and natural environment. The island caters to scuba divers and snorkelers, as the surrounding coral reefs are well preserved and easily accessible from the shore. Bonaire has been widely recognized for many years in the diving community as one of the world's best shore diving destinations. Bonaire's Marine Park offers a total of 86 named dive sites and is home to over 57 species of soft and stony coral and more than 350 recorded fish species. Most resorts and hotels have an on-site dive shop, and other accommodations are affiliated with a dive operation. The license plates carry the logo Diver's Paradise (in English). Lac Bay, in the southeastern part of the island, attracts wind surfers
