The government’s accounting office is questioning sums of RD$137 million and US$61,838 of the funds used to build the airport at La Isabela. The government invested RD$957.5 million and US$4.7 million in the airport facility, which has never been used and is now useless, making it the costliest white elephant in the Dominican Republic. As a result of the audit, the accounting office has requested the District Attorney for Santo Domingo to investigate 13 former officials and contractors of the airport. The audit spanned the period from April 1999 to March 2004. Among the individuals who have been subpoenaed are former officials of the Ministry of Public Works in the administrative, financial and supervisory areas. In the construction of the project, according to the accounting office, the government was bilked in various ways: higher than normal payments for various jobs; payments made in dollars by incorrect means, and payments made to bogus creditors. The office also pointed to discounts that exceed the legal limits for supervisory work, excessive prices for the land and payments for insurance and bonds that were never contracted.
