Prosecutors accuse Mr Iliescu and Mr Voiculescu or "directly spreading misinformation through televised appearances and press releases, contributing to the institution of a generalized psychosis".
Their statements increased the risk of "instances of friendly fire, chaotic shooting and contradictory military orders", prosecutors said.
Their actions are also blamed for the mock trial that resulted in the summary execution of the communist dictator Nicolae Ceausescu and his wife Elena on 25 December 1989.
