the lawyers


Jean-Yves Le Borgne
After studying law at the Université Panthéon-Assas, Jean-Yves Le Borgne was admitted to the Paris Bar in 1973. Elected Secrétaire de la Conférence in 1977, he quickly became a specialist in courtroom hearings and pleadings and has since developed a widely-recognized expertise in criminal law.
Since the early 1990s, he has established himself as a key player in the defense of white-collar crime, and has distinguished himself in sensitive cases, bringing his expertise to bear on political and business figures. He was elected member of the Paris Bar Council in 1992, then Vice-President of the Paris Bar in 2010; the first to hold this position in the history of the French Bar. He was also President of the Criminal Defense Lawyers Association (2003).
An Officer of the Legion of Honor and the National Order of Merit, his commitment to the public service is also reflected in his reflections on reforming the justice system and the judiciary, notably in his two books La garde à vue, un résidu de barbarie (Le Cherche Midi, 2011) and Changer la justice (PUF, 2017). He is also the author of Accusés Levez-Vous (Plon-Gründ, 2022), an illustrated anthology of criminal justice.
