William Bourdon

In 2017, Bourdon was among the co-founders of The Platform to Protect Whistleblowers in Africa (PPLAAF), an organization whose aim is to defend whistleblowers, as well as strategically litigate and advocate on their behalf where their disclosures speak to the public interest of African citizens.

In 2014, he briefly joined the "Nouvelle Donne" party.

In 2012, William Bourdon again grew closer to the Socialist Party and was part of François Hollande's campaign team.

En 2009, William Boudon defended André Barthélemy, president of "Agir Ensemble pour les Droits de l'Homme" before the criminal court of Bobigny for "direct incitement of rebellion" and "deliberately impeding the movement of an aircraft", for having opposed the manner in which two Congolese nationals were escorted back to the border.

In April 2009, he participated in a campaign meeting for the European elections of the Europe Écologie movement coalition (led by Daniel Cohn-Bendit) along with Eva Joly. He proclaimed: "I want to be free of everybody. I do not want to be part of any system."

On October 25, 2007, he filed a defamation complaint "avec constitution de partie civile" against Jeune Afrique and its editor-in-chief, François Soudan, on behalf of Moussa Koussa, head of the Libyan foreign intelligence service. The complaint was voluntarily withdrawn April 10, 2009.

In March 2007, William Bourdon appealed to voters to vote for presidential election candidate Ségolène Royal in a petition published by the Nouvel Observateur.

In 2006, he defended Sud-PTT trade unionist Cyril Ferez who, he said, "took a real beating from 15 or so CRS officers (riot police) for quite a while" during a demonstration against a controversial law concerning work and education. He also defended Yildune Lévy, a close friend of Julien Coupat in the sabotage of SNCF overhead power lines, two French detainees held at Guantánamo sentenced by French justice, or the People's Mujahedin of Iran.

In Sénégal in 2000 Bourdon filed a criminal complaint and charges of torture and crimes against humanity against Hissène Habré in the name of the FIDH. In December 2008, after the failure of complaints against Omar Bongo, Denis Sassou Nguesso, and Teodoro Obiang Nguema Mbasogo, Sherpa and Transparency international filed a complaint against person or persons unknown on the conditions under which a lot of movable and fixed assets were acquired in France by these African heads of state. In 2005 he defended, Motassim Bilal " Hannibal " Kadhafi, son of Colonel Mouammar Kadhafi, sentenced May 23, 2005 by the 10th Chamber of the Tribunal correctionnel de Paris to four months imprisonment, suspended, for domestic violence.

The arrêt of the chambre d'accusation [fr] of Paris, the investigative arm of the court of appeal, on October 20, 2000 authorized the complaint of the victims of UTA Flight 772 against Muammar Gaddafi. Considering that "originally absolute, the immunity of heads of state has, since the end of the Second World War, had limits," William Bourdon declared in an interview with Libération that the arrêt might create "confusion", since only three crimes have universally justified lifting presidential immunity: genocide, crimes against humanity and war crimes: "Terrorism is a very subjective crime. If one reasons in this manner, Yasser Arafat could be pursued," observed Maître Bourdon, underlining that terrorism and narcotics trafficking were deliberately omitted when the International Criminal Court (ICC) was created. In keeping with this point, the parquet général asked the Court of Cassation to pronounce for the first time on the controversial question of the immunity of heads of state. This motion does not require suspending the current investigation.

William Bourdon was Under Secretary-General (1994–1995), then Secretary-General of the Fédération internationale des droits de l'homme from 1995 to 2000. In October 2001, he founded Sherpa, whose goal is to "defend the victims of crimes committed by economic operators." He is also currently the organization's president. Sherpa is housed on the premises of France Libertés [fr] ; William Bourdon is a member of the Conseil d'administration (administrative council) of France Libertés and is the longtime lawyer of Danielle Mitterrand.

William Bourdon was also the lawyer for Transparency International, Survie and the Fédération des Congolais de la Diaspora (FCD). He is close to associations who provide help to foreign nationals without proper papers, such as Cimade, for whom he acted as an observer in 1992.

William Bourdon distinguished himself in criminal law in the 1980s, for example with the defence of prostitutes in the Jobic affair, a police commissioner accused of procuring before finally being released.
