COMPAGNIE DES EXPERTS DE JUSTICE DE LYON

What COMPAGNIE DES EXPERTS DE JUSTICE DE LYON does

The Compagnie des Experts de Justice de Lyon is a Loi 1901 non-profit professional association founded on May 4, 1959 and headquartered at 74 rue de Bonnel, 69003 Lyon, France. It groups more than 650 court-approved judicial experts (auxiliaires de justice) inscribed on the official lists of the Cour d'appel de Lyon and the administrative courts, covering nine specialty branches: agriculture, arts & culture, construction, economics & finance, industry, health, criminalistics, interpretation & translation, and environment. The association is administered by an elected board led by President Dr Pierre PADZUNASS (elected April 23, 2026), Treasurer Philippe MOREL, and Secretary General Arnauld RAYÉ, supported by 17 staff members.

Its three core offerings are: (1) the Répertoire des Experts de Justice — a searchable online directory of expert witnesses by name or specialty code; (2) the Centre de Formation des Experts — France's first training center for judicial expertise, delivering initial formation, common core training, and branch-specific continuing education (e.g., a 2-day, 16-hour course in September 2026 priced at 450 EUR per participant); and (3) Location de Salle — a video-conferencing-equipped meeting room rental at the headquarters, accommodating up to 15 people for expert evaluations.

The business model combines recurring membership subscriptions from individual expert members with per-seat training fees and ancillary room-rental income. Distribution is regional, serving the Cour d'appel de Lyon jurisdiction and adjacent courts in Chambéry, Grenoble, Dijon, and Riom, with mutual partnerships established with the corresponding regional expert associations. The primary end-users are French courts, lawyers, parties to legal proceedings, and prospective judicial experts preparing for registration under Decree 2023-468. The organization is not a technology company; its core technology is the curated human directory and in-person training infrastructure rather than any software platform.

Direct peers

• Compagnie des Experts de Justice de Riom: Companion Compagnie des Experts de Justice serving the Riom jurisdiction in Auvergne. Already a minor strategic partner of the Lyon Compagnie; structurally identical as a French regional association of judicial experts.
• Compagnie des Experts de Justice de Grenoble: Regional judicial experts association covering the Grenoble court of appeal. A formal partner of the Lyon Compagnie; comparable in scope and operating model within a neighboring French jurisdiction.
• Compagnie des Experts de Justice de Bordeaux: Regional judicial experts association covering the Bordeaux court of appeal. Provides the same directory, training, and member services as Lyon but in southwestern France; another directly comparable peer.
• Compagnie des Experts de Justice de Paris: Paris-based peer association of court-approved judicial experts. Same legal and professional mission as the Lyon Compagnie (directory of experts, training, networking), but serving the largest French court of appeal jurisdiction; the most comparable direct peer in terms of structure, activities, and member base.
• Compagnie des Experts des Savoie (Chambéry): Companion judicial experts company based in Chambéry covering the Savoie area. Listed as a regional partner with mutual collaboration; equivalent in form and function to the Lyon Compagnie.
• Compagnie des Experts de Justice de Marseille: Regional Compagnie des Experts de Justice serving the Marseille court of appeal jurisdiction. Operates a directory, training programs, and member services analogous to those of Lyon; an obvious functional peer in a different metropolitan geography.

Regional players

• Expert Witness Institute (UK): UK professional body representing expert witnesses; provides a directory, training, and accreditation analogous to what the Lyon Compagnie offers. Comparable in mission even though it operates under a different legal regime (English courts rather than French cours d'appel).

Broad incumbents

• Société Française d'Expertise Judiciaire: France-wide learned society working on methodologies and standards for judicial expertise. Broader and more academic than the Lyon Compagnie but operates in the same ecosystem of court-appointed technical expertise.
• Compagnie Nationale des Experts de Justice (CNCEJ): National federation of French judicial expert companies. CNCEJ is the umbrella body that the Lyon Compagnie is affiliated with (visible on its website footer); it operates broadly across France, defining national standards and representing the profession at the federal level rather than running a regional directory.

Others

• LexisNexis Expert Directory / Westlaw Expert Witness Index: Commercial legal information providers offering expert witness directories as part of their broader legal research platforms. Not a peer in terms of business model but an adjacent competitive force that lawyers use in parallel to regional Compagnie directories.
