Former president Miguel Ángel Rodríguez is going on trial again along with seven other former public employees.
The Poder Judicial said Tuesday that the Juzgado Penal de Hacienda has ordered the opening of a new trial.
The case involves the reinsurance premiums paid by the Instituto Nacional de Seguros to a large London firm to cover the activities of the Instituto Costarricense de Electricidad. Insurance firms typically use reinsurance to spread out their risks.
Other defendant include the former head of the state insurance company and employees of both state agencies.
Prosecutors charge that some of the money was diverted and ended up in the hands of officials here.
No date has been set for the trial, which will be open to the public. A judicial panel at one point threw out the case, but prosecutors appealed successfully to have it reinstated, They said they were informed of the judicial ruling Tuesday afternoon.
