Judgment summary
The case concerns a request for a preliminary ruling from the Cour administrative (Luxembourg) on the interpretation of Article 17(1) and (4) and Article 18(1) of Directive 2011/16/EU on administrative cooperation in taxation, and on Article 7 and Article 52(1) of the Charter of Fundamental Rights of the European Union (para 1).
The dispute arose after the Luxembourg Inland Revenue, acting on a request from the Spanish tax authorities under Directive 2011/16, ordered F SCS, a Luxembourg law firm, to provide all documentation concerning legal services it had rendered to a Spanish company, K, in connection with corporate acquisitions (paras 22-23). F SCS refused, invoking legal professional privilege, and was subsequently fined for non-compliance (paras 24-28).
The referring court asked the Court of Justice, in essence, whether legal advice on company law matters is protected by Article 7 of the Charter, whether Directive 2011/16 is valid in light of Articles 7 and 52(1) of the Charter despite not itself defining limits on lawyer-client confidentiality, and whether Luxembourg's Article 177 of the AO (General Tax Law), which largely removes privilege for tax-related legal advice, is compatible with the Charter (paras 33-41).
Background
F SCS is a law firm incorporated as a limited partnership in Luxembourg (para 2). Following a request for information based on Directive 2011/16 from the Spanish tax authorities, on 28 June 2022 the Luxembourg Inland Revenue issued a decision ordering F to provide all available documentation and information concerning services it provided to K, a Spanish company, in connection with the acquisition of a business and of a majority shareholding in another Spanish company, covering the period from 1 January 2016 to 31 December 2019 (paras 22-23).
F responded by email of 8 July 2022 that it had acted as legal counsel for the group and was prevented by legal professional privilege from disclosing the information (para 24). After further correspondence, in which F maintained on 8 August 2022 that its instructions concerned company law rather than tax matters (para 26), the Luxembourg Inland Revenue issued a further decision on 19 August 2022 again ordering disclosure on pain of a fine (para 27), and on 16 September 2022 imposed that fine for non-compliance (para 28).
F brought actions before the Tribunal administratif seeking annulment of both decisions, and the Ordre des avocats du barreau de Luxembourg (OABL) sought to intervene in support of F (para 29). The Tribunal administratif dismissed the action and found the OABL's application to intervene inadmissible ratione temporis by judgment of 23 February 2023 (para 30). On appeal, the Cour administrative held, by judgment of 4 May 2023, that both the action and the intervention were admissible, and referred six questions to the Court of Justice (paras 31-41).
Core dispute
The dispute centred on whether a decision ordering a lawyer to disclose all documentation and information relating to legal advice given to a client, for the purposes of an exchange of information on request under Directive 2011/16, interferes with the right to respect for lawyer-client communications under Article 7 of the Charter, irrespective of the area of law concerned (paras 33-35, 46).
A further issue was whether Directive 2011/16 is itself invalid in light of Articles 7 and 52(1) of the Charter, given that, beyond Article 17(4), it contains no provision expressly permitting interference with lawyer-client confidentiality in the context of exchange of information on request, nor any provision defining the scope of such a limitation, while Article 18(1) refers the matter to national law (paras 36-37, 53).
Finally, the referring court asked whether, and under what conditions, national legislation such as Article 177 of the AO, which largely excludes legal professional privilege for advice given by lawyers in tax matters (save where the client faces a risk of criminal prosecution), and its application in the decision at issue, comply with Article 7 and Article 52(1) of the Charter (paras 37-40, 65).
Court findings
On the first two questions, the Court held that legal advice given by a lawyer, whatever the area of law to which it relates, enjoys the strengthened protection guaranteed by Article 7 of the Charter to communications between lawyers and their clients (para 51). A decision requiring a lawyer to provide all documentation and information relating to his or her relations with a client concerning such advice therefore constitutes an interference with that right (para 52).
On the third and fourth questions, the Court found nothing to affect the validity of Directive 2011/16 in light of Articles 7 and 52(1) of the Charter. The directive merely determines reciprocal obligations between Member States for exchange of information on request and leaves it to each Member State to ensure, in its national information-gathering procedures, that Article 7 of the Charter is respected and that any limitation is 'provided for by law' within the meaning of Article 52(1) (paras 59-61).
On the fifth and sixth questions, the Court held that Article 177 of the AO, by excluding the content of advice given by lawyers in tax matters almost entirely from strengthened privilege protection, renders that protection devoid of substance in that branch of law (para 72). The decision at issue, presupposing that non-applicability of privilege authorised the tax authorities to demand F's entire file, further extended that infringement (para 72). Such a provision and its application, far from being confined to exceptional situations, infringe the essence of the right guaranteed by Article 7 of the Charter and constitute an unjustifiable interference (paras 73-74).
Outcome
The Court ruled, first, that Article 7 of the Charter must be interpreted as meaning that legal advice given by a lawyer in company law matters falls within the strengthened protection of lawyer-client communications, so that a decision requiring disclosure of all related documentation and information constitutes an interference with that right.
Second, the examination of the third and fourth questions disclosed nothing capable of affecting the validity of Directive 2011/16 in light of Article 7 and Article 52 of the Charter.
Third, Article 7 and Article 52(1) of the Charter preclude a decision such as that at issue, based on national legislation under which advice and representation by a lawyer in tax matters do not enjoy the strengthened protection of Article 7, except where there is a risk of criminal prosecution against the client.
Major issues / areas of contention
- Whether legal advice given by a lawyer on company law matters falls within the strengthened protection of lawyer-client communications under Article 7 of the Charter, regardless of the area of law involved.
- Whether a tax authority decision compelling a lawyer to disclose an entire client file, including a detailed description of transactions and communications, constitutes an interference with Article 7 of the Charter.
- Whether Directive 2011/16/EU is invalid under Articles 7 and 52(1) of the Charter for not itself expressly permitting or defining the scope of any interference with lawyer-client confidentiality in the context of exchange of information on request.
- Whether Article 18(1) of Directive 2011/16 permits Member States' domestic law to govern the scope of a lawyer's duty of cooperation as a third-party information holder, including limitations reflecting legal professional privilege.
- Whether Luxembourg's Article 177 of the AO, which withdraws legal professional privilege for advice given by lawyers in tax matters (save where the client risks criminal prosecution), infringes the essence of the right guaranteed by Article 7 of the Charter.
