William JULIÉ is a bilingual English French Avocat specializing in:

– Criminal law / Extradition  / White Collar crime 

– INTERPOL / Red Notice / Crisis Management

– Human Rights

– Corporate Counsel and Arbitration

He was admitted to the Paris Bar in 2000 and established his own practice in 2002. His dual nationality and his fluency in English has enabled him to develop an extensive domestic and international network, generating a substantial body of work in Human Rights and international criminal law.

After his BA in international law and his MA in public law from the University of Paris-Sorbonne (Paris I), William specialized in criminal law and criminology, obtaining a doctoral certification (Doctorat d’Etudes Approfondies) in European criminal justice policy, directed by Professor Myriam Delmas Marty, also at the University of Paris-Sorbonne.

As a young Avocat, he worked alongside Henri Leclerc (President of the French Human Rights League), Eric Plouvier (founder of Human Rights Certification) and Dominique Tricaud, specialized in high-profile UK & US extradition cases. The experience gained during these years strengthened William’s commitment to criminal defense and upholding human rights, both nationally and internationally.

William’s expertise was rapidly tuned, thanks to several politically sensitive cases he handled soon after establishing his own practice.

The first concerned the music industry and resulted, in 2002, in his participating in negotiations with Jacques Lang, the then Culture Minister in Lionel Jospin’s Government, to draft a bill prohibiting open-air electronic music gatherings.

Another was the historic Outreau pedophile ring trial in 2004 and the subsequent 2006 Parliamentary Enquiry into miscarriages of justice in the said case, before which William testified.

He was furthermore involved in several anti-terrorist cases in relation to ETA, Al Qaida, the Ultra Left, and more recently to the so-called Islamic State (domestic recruitment networks for djihad fighters). He also defends victims of terrorism, including the November 2015 Paris attacks.

In his daily practice William has for years handled a considerable volume of high profile crime cases, examples of which follow.

Between 2006 and 2008, subsequent to the Simon Price 35 million pound cocaine haul in the UK, he entirely nullified all proceedings regarding the seizure of properties in France.

In 2010 he obtained the transfer back to France and immediate release of Emmanuel Henning, sentenced in GB for a 54 million pound mobile phone carousel fraud.

In 2012, he represented one of the prime suspects in the Tobago Clipper case, an extended network importing South American cocaine (almost 4 tonnes), in which his client was acquitted.

Since 2013 he has also dealt with embezzlement cases related to works of art or excisable products such as alcohol and tobacco, especially in Northern France, Spain, Portugal and Switzerland.

More recently, he has advised sportsmen as to their transfers, disciplinary procedures and career orientations. He has also established quality contacts within the music and event management industries (Mixed Martial Arts, Rap and R&B Music, etc.).

In the political sphere, he has represented several civil servants in misappropriation of public funds cases, as well as town councillors in electoral disputes and controversy with the press (Puteaux Town Council). He also advised members of the diplomatic corps at the Syrian and Tunisian Embassies in Paris, as well as prominent persons close to the President of the Senegalese Republic and the City of Dakar Council. More recently, he has been involved in high profile cases in the Middle-East, specifically in Lebanon, the United Arab Emirates, Saudi Arabia, Jordan, Irak, Pakistan, South America, Hong Kong and Russia.

In Human Rights and Extradition matters, he handles cases in and outside the EU, including the USA, China, Africa, India and many other countries in the world. He has established successful and ongoing collaboration with various Human Rights and extradition lawyers worldwide.

Since 2017, he has set up a special group within the firm specialised in INTERPOL and Red Notice issues that focuses on all levels of legal action, including public relation and lobbying advice and interacting with leading governmental investigating or intelligence services.
