Summary of Update:
On 18 February 2026, the French Constitutional Council upheld Article 1 of Law No. 2026‑122 extending the scope of legal privilege to consultations prepared by in‑house counsel, following its adoption by the French Senate on 14 January 2026 after many years of debate.
The protection is limited to legal consultations, defined as "a personalised intellectual service aimed at providing an opinion or advice based on the application of a legal rule". The protection applies subject to four cumulative conditions being met, which relate to the in‑house counsel’s qualifications, ethical training, the express labelling of the document as “confidential – legal consultation – in‑house counsel,” and its circulation being strictly limited to senior management of the company, its controlling entity, or the entity advising the management of the employing company.
Where these conditions are satisfied, consultations prepared by in‑house counsel are immune from seizure by public authorities in civil, commercial, or administrative proceedings. However, the competent administrative authority may, within a period of 15 days, bring the matter before the Judge of Freedoms and Detention, either to challenge the applicability of legal privilege or to seek its waiver where the consultation is alleged to have facilitated or encouraged breaches of regulatory requirements.
From a competition law standpoint, several limitations warrant emphasis. Firstly, this protection does not apply in criminal proceedings and therefore does not extend to criminal investigations into anticompetitive conduct under article L.420-6 of the French Commercial Code. Secondly, the French Constitutional Council has expressly clarified that this protection is inapplicable to inspection procedures carried out directly by the EC or by another EU authority acting under its investigative powers, or, where such powers have been delegated, by the departments of a national authority.
Notably, this law was adopted shortly after the EC's publication of a competition law brief discussing the extension of legal privilege to in-house counsel. In that brief, the EC underlined that this would most likely hamper the effectiveness of EU competition law investigations and proceedings. As early as 2023, when the law was under discussion, a French deputy mentioned the existence of a letter from the EC's former Executive Vice‑President, Margrethe Vestager, emphasising that the measure would not be enforceable against the FCA when applying Articles 101 and 102 TFEU.
Additional implementing conditions, in particular those relating to the law’s entry into force, will be specified by decree. Notwithstanding the significance of this legislative development, its practical impact on competition proceedings remains uncertain, given that most investigations are primarily conducted under EU law (Articles 101 and 102 TFEU).
Sector Relevance: General.
Why it matters / Key takeaways
While legal privilege now covers legal consultations prepared by in‑house counsel, subject to conditions, its practical application in FCA investigations conducted under EU law remains to be clarified.
