A prominent legal proceeding commenced in Paris on Monday as Joël Guerriau, a 68-year-old former French senator, stands trial for allegedly drugging fellow parliamentarian Sandrine Josso with intent to commit sexual assault. The case has drawn national attention to drug-facilitated crimes in France, echoing the groundbreaking Gisèle Pelicot trial that previously captivated the nation.
According to court documents, Guerriau faces multiple charges including drug possession, administration of mind-altering substances, and attempted sexual assault. The incident occurred when Josso, a 50-year-old centrist lawmaker, visited Guerriau’s Paris apartment under the presumption of celebrating his reelection. Having maintained a professional friendship for years, Josso accepted champagne that she later discovered contained MDMA.
Josso described experiencing immediate physical distress including heart palpitations and sensations resembling cardiac arrest. Her testimony reveals she identified a suspicious packet in Guerriau’s hand before promptly leaving the premises via taxi and seeking hospital treatment. Medical examinations confirmed MDMA presence in her bloodstream.
The defense team contends the incident resulted from a ‘handling error,’ claiming Guerriau had prepared the substance for personal use during a depressive episode and accidentally served the tainted glass. They maintain no assault intention existed. Despite remaining in office for nearly two years post-charges, Guerriau resigned in October while denying any connection between his resignation and legal proceedings.
This case occurs against the backdrop of France’s evolving legal landscape regarding sexual violence. The recent Pelicot trial, which convicted 51 men for systematic assaults under chemical submission, prompted legislative reforms. In October 2025, France adopted a consent-based definition of rape, eliminating previous requirements for proving violence or coercion.
Josso has emerged as a significant advocate against drug-facilitated crimes, collaborating with Pelicot’s daughter and co-authoring parliamentary reports on chemical submission assaults. The trial outcome could set important precedents for similar cases, with Guerriau potentially facing up to 15 years combined imprisonment for drug and assault charges.
