Paris' chief prosecutor demanded the court hand down an 18-month suspended sentence plus a 45,000-euro fine to former Prime Minister Dominique de Villepin for his alleged role in the Clearstream affair.
He also recommended sentences for former head of EADS Jean-Louis Gergorin and IT expert Imad Lahoud in the case. He called for two years in prison including 6 months suspended for Lahoud, and 3 years including 18 months suspended for Gergorin.
Earlier in his summing up, Mr Marin insisted that the trial, pitting de Villepin against President Nicolas Sarkozy, was not politically motivated.
"It is not opinions or political opponents who are on trial here, but defendants," said Paris prosecutor Jean-Claude Marin during his closing arguments in the month-long hearings.
"This trial is the trial of unacceptable methods," said Marin, "of behaviours on the part of certain men who believe the end justifies the means." added Mr Marin.
De Villepin is charged with plotting to smear Sarkozy and wreck his chances for the presidency in 2004.
At the time both men were jostling to succeed President Jacques Chirac.
Once Chirac's preferred heir, de Villepin is charged with complicity to slander and using forgeries, dealing in stolen documents and breach of trust.
Sarkozy's name was on the list. He alleges the scandal was fabricated to tarnish him during his campaign for the party's nomination ahead of the 2007 vote, which he won.
They also asked for former Arthur Andersen intern Florian Bourges, who passed on Clearstream documents to Robert, to be convicted of breach of trust but not theft.
Judges are not expected to reach a verdict before January.
