 Main achievements of his government
 After an alleged corruption scandal he was incarcerated in October 2004. He was released from jail and was placed under house arrest.
 Calderon Fornier was accused of receiving money from the Finnish firm Instrumentarium in exchange of contracts for the firm with the Caja Costarricense del Seguro Social (CCSS). His trial started on 3 November 2008, and the hearings finished in September 2009. In spite of the charges, he officially announced his candidacy for the Presidency of Costa Rica in 2010 elections.  On 5 October 2009 Calderón was sentenced to five years in prison. He walked out of the court room and notified the press that he would appeal the sentence and that he was not running for president in order to focus on his appeal.
 Calderon Fournier's co-defendants received varied sentences. Walter Reiche (an executive from Costa Rican firm Corporación Fischel) was sentenced to serve four years of prison. Eliseo Vargas García, former CEO of CCSS was sentenced to serve a five-year term in prison. Gerardo Bolaños Alpízar, a former member of the CCSS board was sentenced to three and a half years in prison; the same sentence as Juan Carlos Sánchez Arguedas, an executive of CCSS, and Marvin Barrantes, CEO of Corporación Fischel.
 On 11 May 2011 Calderon Fournier's appeal was rejected by the tribunal (the so-called Sala III). The judges confirmed the previous sentence. However, they reduced the term to serve in prison from five years to three. According to the Costa Rican law, he can be expected not to serve this time in prison. Calderon's wife, Mrs. Gloria Bejarano Almada, who currently serves as a deputy at the Asamblea Legislativa (congress of the country) and who is a member of the parliament's directorate, was sentenced to pay US$70,000 to the Costa Rican government for her participation in the scandal. According to the ruling, Mrs. Bejarano Almada obtained an economic profit in the scandal. On 13 April, the Costa Rican newspaper La Nación informed that Finland's attorney general will press charges against three executives from the Finnish firm Instrumentarium. The three executives will be charged of crimes connected with corruption and fraud related to a loan of $39.5 million granted by the Finnish government to the Caja Costarricense de Seguro Social (the Costa Rican agency in charge of public hospitals) and intended to finance the purchase of medical equipment. According to the Finnish attorney general, the accused executives, who worked for Instrumentarium Medko Medical, later acquired by General Electric, distributed a total of $8.7 million to Costa Rican partners and public servants in kick-backs. The attorney general believes that the trial could begin by September, 2012 and that a sentence would be pronounced early 2013.
