Diane Bandon-Tourret

Diane Bandon-Tourret is an attorney at the Paris Bar and a partner at LexCase, where she leads the firm's health industries and health products department. At the Corporate INTL Global Awards 2025, LexCase was recognised as Healthcare Enforcement Law Firm of the Year in France, an accolade that reflects the depth of its regulatory and contentious work for the life sciences and healthcare sectors, a field in which Ms Bandon-Tourret is one of the country's most established practitioners.

Ms Bandon-Tourret has led LexCase's healthcare industries team since 2019, having previously been an Of Counsel at the firm. Over the course of her career she has practised in both French and Anglo-Saxon law firms, including Courtois Lebel, Bird & Bird and SEA Avocats, and she holds a Master's degree in medical and pharmaceutical liability law. She also teaches health products law at the Catholic University of Lille, and has been repeatedly recognised among the leading practitioners in the Life Sciences category by the Who's Who Legal directory, a mark of the peer esteem in which her work is held.

Her practice is built around the regulated activities of the health industries. She advises pharmaceutical laboratories, medical device manufacturers, cosmetics and food-supplement companies, biotechs and contract research organisations, acting both in advisory work and in litigation. Her expertise covers the areas where regulation and enforcement bite hardest: market authorisation and access, pricing, the promotion and advertising of health products, anti-corruption and transparency compliance within the sector, and the sensitive question of product withdrawals. This is precisely the terrain of healthcare enforcement, where companies must navigate the demands of regulators such as the ANSM and manage the legal consequences when products, claims or conduct are challenged.

LexCase itself is a French firm operating from four offices in Paris, Lyon, Marseille and Bordeaux, and it describes its ethos through the idea of lawyers as entrepreneurs, offering a complete legal service to support clients' projects at regional, national and international level. Within that structure, the health industries and health products practice stands out as a recognised centre of expertise, supported by a steady flow of specialist commentary on regulatory developments affecting medical devices, health-product advertising and the sanctions imposed by health authorities. The firm's broader standing is reflected in its recognition by directories including Best Lawyers, The Legal 500, Chambers and Partners and Décideurs Magazine.

What distinguishes Ms Bandon-Tourret's contribution is the way she pairs technical regulatory knowledge with practical experience of enforcement and dispute. Health-sector clients face an environment in which a single regulatory decision, advertising challenge or compliance failure can carry significant financial and reputational consequences, and in which the rules are constantly evolving under both French and European influence. Her ability to advise on the regulatory framework before problems arise, and to defend clients robustly when they do, gives the practice a rounded capacity that spans prevention and response.

Through her leadership of LexCase's health industries team, Diane Bandon-Tourret has helped establish the firm as a trusted adviser to companies operating at the demanding frontier of healthcare regulation and enforcement in France. The Corporate INTL Global Awards 2025 recognition as Healthcare Enforcement Law Firm of the Year affirms the strength of that practice and the confidence it commands among life sciences clients. For pharmaceutical, device, biotech and consumer-health businesses seeking counsel that understands both the science-driven regulatory landscape and the realities of enforcement, the firm offers experienced, sector-focused representation grounded in years of specialist practice.
