Xavière Tiberi received 200,000 French Francs for a report on francophonie for the general council of the Essonne département. This 36-page long report, possibly written after the payment as a justification, was extremely poorly written (contained numerous spelling and grammatical mistakes, for instance).
In 1998, a justice-ordered search of Jean and Xavière Tiberi's apartment on the Place du Panthéon showed that they possessed illegal firearms. They were not prosecuted in exchange for the destruction of the weapons.
The above actions are sometimes referred to by the press as Corsican mores
On November 9, 2004, Xavière Tibéri and Aurélie Filipetti, an elected official from the French Green Party, wrangled after a tense district council meeting. Each of them accused the other one of assault or threats. Mrs Tibéri had a head trauma, which she claimed was caused by Mrs Filipetti pushing her over; she filed a complaint.
