public works. The Urba affair became public in 1989 when two police officers investigating the Marseille regional office of Urba discovered detailed minutes of the organisation's contracts, which showed a division of proceeds between the party and elected officials. Although the minutes proved a direct link between Urba and corrupt payments to politicians, an edict from the office of François Mitterrand (even though he himself was listed as a recipient) prevented further investigation. The François Mitterrand election campaign of 1988 was directed by Henri Nallet, who then became Justice Minister and therefore in charge of the investigation at national level. In 1990 François Mitterrand declared an amnesty for those under investigation, thus ending the affair. Socialist Party treasurer Henri Emmanuelli was tried in 1997 for corruption offences, for which he received a two-year suspended sentence. Wiretaps From 1982 to 1986, François Mitterrand established an "anti-terror cell" installed as a service of the President of the Republic. This was an unusual set-up, since such law enforcement missions against terrorism are normally left to the National Police and Gendarmerie, run under the cabinet and the Prime Minister, and under the supervision of the judiciary. The cell was largely staffed by members of these services, but it bypassed the normal line of command and safeguards. Three thousand conversations concerning 150 people (7 for reasons judged to be contestable by the ensuing court process) were recorded between January 1983 and March 1986 by this anti-terrorist cell at the Elysée Palace. In one of its first actions, the cell was involved in the "Irish of Vincennes" affair, in which it appeared that members of the cell had planted weapons and explosives in the Vincennes apartment of three Irish nationals who were arrested on terrorism charges. Most markedly, it appears that the cell, under illegal presidential orders, obtained wiretaps on journalists, politicians and other personalities who may have been an impediment for François Mitterrand's personal life. The illegal wiretapping was revealed in 1993 by Libération; the case against members of the cell went to trial in November 2004. It took 20 years for the affaire to come before the courts because the instructing judge Jean-Paul Vallat was at first thwarted by the affaire being classed a defence secret, but in December 1999 the Commission consultative du secret de la défense nationale declassified part of the files concerned. The judge finished his investigation in 2000, but it
