The Court of Appeal has ruled that breaching anti-money laundering regulations does not automatically amount to professional misconduct. Dentons UK and Middle East LLP v SRA [2026] EWCA Civ 508 establishes that there is an inherent threshold of seriousness in all SRA Principles — and that the Solicitors Disciplinary Tribunal is entitled to dismiss a disciplinary charge even where a regulatory breach has been proved. For every compliance team in England and Wales, this decision defines the line between a regulatory failing and a finding of misconduct.

What Happened
The case concerns Dentons UK and Middle East LLP, which inherited a client relationship with a politically exposed person following its 2013 merger with the Paris-based firm Salans LLP. The client — referred to as “Client A” in the proceedings, and identified in press reporting as Jahangir Hajiyev, former chairman of the state-owned International Bank of Azerbaijan — was classified by Dentons as high risk. An internal intelligence note described him as “supremely unlikely” not to have benefited from approximately $1 billion that had gone missing from the bank he chaired.
Despite this assessment, the firm continued to act for Client A in 38 matters between 2013 and 2017, including the purchase of an £8 million UK property. The firm relied on assurances from a former Salans partner — who was not SRA-regulated — regarding the client’s source of wealth. In 2016, Client A was sentenced to 15 years’ imprisonment for crimes including embezzlement. Two years later, his wife became the subject of the UK’s first unexplained wealth order, brought by the National Crime Agency in respect of properties valued at over £22 million.
The SRA charged Dentons with three breaches of the SRA Principles 2011 and the SRA Code of Conduct 2011, centred on the firm’s failure to carry out adequate source-of-wealth and source-of-funds checks as required by Regulation 14 of the Money Laundering Regulations 2007.
Three Courts, Three Answers
The case has produced a different result at each level, reflecting a genuine and unresolved tension in the regulatory framework.
The Solicitors Disciplinary Tribunal (March 2024) found that Dentons had breached the Money Laundering Regulations — the firm’s source-of-wealth checks were inadequate. But the Tribunal concluded that this breach was not sufficiently serious or culpable to amount to professional misconduct under the SRA Principles. It dismissed the disciplinary allegations and made no order against the firm.
The High Court (March 2025) allowed the SRA’s appeal. Lang J held that any breach of the Money Laundering Regulations automatically constituted a breach of Principle 7 (“You must comply with your legal and regulatory obligations”) and Outcome 7.5 (“you comply with legislation applicable to your business, including anti-money laundering… legislation”). On this reading, once a regulatory breach was proved, the question of seriousness was relevant only to sanction, not to whether there had been misconduct at all. Lang J quashed the Tribunal’s decision and remitted the entire case to a fresh panel.
The Court of Appeal (27 April 2026) allowed Dentons’ appeal in part. Bean LJ (Vice-President of the Court of Appeal, Civil Division), Jeremy Baker LJ, and Zacaroli LJ rejected the SRA’s interpretation and held that there is an inherent threshold of seriousness in all SRA Principles — including Principle 7. The case was remitted to the SDT, but only on the Principle 7 and Outcome 7.5 charges. The Court of Appeal upheld the Tribunal’s dismissal of the other allegations.
The Legal Reasoning
The central question was whether the words of Principle 7 — “You must comply with your legal and regulatory obligations” — meant that any breach of any legal obligation, however minor, automatically constituted a disciplinary violation.
The Court of Appeal rejected what it called the “grammatical interpretation” advanced by the SRA. It identified two fundamental objections.
First, treating every regulatory breach as automatic misconduct would represent a dramatic departure from the common law understanding of professional discipline. Lord Denning MR’s formulation in In re a Solicitor [1972] 1 WLR 869 — that misconduct requires a considerable level of seriousness — has stood for over fifty years. The SRA’s interpretation would collapse the distinction between a technical regulatory infringement and conduct warranting professional sanction.
Second, the interpretation would produce anomalous results within the SRA’s own framework. As the Court observed, it would be illogical that an allegation of failing to provide a proper standard of service (Principle 5) should require an assessment of seriousness, while a failure to comply with any legal provision (Principle 7) — however trivial — would automatically establish a disciplinary violation. The Principles must be read consistently.
The Court reconciled the two Divisional Court authorities that had been in apparent tension. In SRA v Leigh Day [2018] EWHC 2726 (Admin), the Divisional Court had held that a breach of a core Principle required sufficient seriousness and culpability. In Beckwith v SRA [2020] EWHC 3231 (Admin), the court appeared to take a stricter approach. The Court of Appeal held that the two cases were not in conflict: Beckwith involved breaches of Principles 2 and 6, which inherently involve evaluations of seriousness (integrity, public trust), while Leigh Day established the general proposition that seriousness must be assessed.
The Court’s conclusion, at paragraph 120, set out the test going forward: the question for the SDT in any case is whether the conduct in question would be considered sufficiently serious by competent and reputable solicitors to be categorised as professional misconduct.
What Happened to the Charges
The practical outcome was a split decision.
The Court of Appeal upheld Lang J’s quashing of the Tribunal’s decision on the Principle 7 / Outcome 7.5 charge (failure to comply with anti-money laundering legislation). That charge is remitted to a fresh SDT panel for reconsideration — but under the seriousness test, not the automatic-breach test. The new panel must decide whether Dentons’ admitted failure to carry out adequate source-of-wealth checks was sufficiently serious to amount to professional misconduct.
The Court of Appeal allowed Dentons’ appeal against the remittal of the Principle 6 (public trust) and Principle 8 (run your business effectively) charges. The Tribunal had dismissed those charges, and the Court of Appeal held that the Tribunal was entitled to do so.
The result is that Dentons returns to the Tribunal on a single charge, with the seriousness threshold firmly in play. The firm is not “cleared” — it retains a published finding that it breached the Money Laundering Regulations — but the disciplinary question remains open.
Why This Matters
The significance of Dentons extends well beyond one firm’s AML compliance. The decision establishes three propositions of general importance.
First, legal breaches and disciplinary breaches are not the same thing. A firm can be found to have breached a statutory or regulatory requirement without that breach amounting to professional misconduct. This preserves the distinction between regulatory compliance (which may be enforced by the relevant regulator under its own enforcement powers) and professional discipline (which requires a qualitative assessment of the conduct’s seriousness).
Second, the seriousness threshold applies to all SRA Principles. The Court of Appeal rejected the argument that some Principles carry an inherent seriousness requirement while others are strict liability. Principle 7 is not a strict-liability gateway through which the SRA can bring any regulatory breach to the Tribunal without establishing that the breach was serious enough to warrant disciplinary proceedings.
Third, the SDT’s evaluative function is protected. The Tribunal is not a rubber stamp. It retains the jurisdiction — and the duty — to assess whether proved conduct crosses the threshold of professional misconduct. The High Court’s approach, which would have required the Tribunal to find misconduct wherever a regulatory breach was established, has been rejected.
The Counterpoint: What Dentons Does Not Do
The decision has drawn criticism from anti-corruption organisations and AML enforcement advocates, and the counterarguments are serious.
Spotlight on Corruption, which has tracked the case closely, has argued that the Tribunal’s original finding — that Dentons’ AML failures were “not serious” despite involving a high-risk client who was subsequently imprisoned — demonstrates a fundamental failure to appreciate the importance of source-of-wealth checks in preventing money laundering through UK property transactions. The SRA’s own enforcement guidance identifies property as the main vulnerability in the legal sector for money laundering risk.
The concern is that Dentons creates a gap: firms that breach AML requirements may face regulatory findings but escape disciplinary consequences, particularly where the breach is characterised as “inadvertent” or the firm cooperated with the investigation. The SRA did not challenge the Tribunal’s factual finding that Dentons’ breach was inadvertent and committed in good faith — a strategic decision that limited the grounds of appeal but left those findings intact.
The Doughty Street Chambers analysis by Peter Caldwell KC and Natalie Lucas identifies the core tension: the SRA’s increasingly exacting regulatory expectations (including the February 2026 updated sanctions guidance and the OFSI Strategy 2026–29) are raising the standard of expected conduct, while Dentons preserves a judicial threshold that limits the disciplinary consequences of falling short. Practitioners are caught between rising expectations and an enduring requirement of proportionality.
The Broader Regulatory Context
The decision lands at a moment of significant regulatory activity on multiple fronts.
The SRA published updated guidance on complying with the UK sanctions regime in February 2026, which places considerable weight on the adequacy of firms’ systems and controls and makes clear that failure to follow the guidance may be treated as an aggravating factor in enforcement proceedings. OFSI’s Strategy 2026–29 signals a move toward more proactive, intelligence-led enforcement and greater coordination between regulators and law enforcement.
The SRA’s December 2025 thematic review of compliance officers found that only 1 out of 36 COLPs interviewed could describe all of their regulatory obligations — a finding that sits uncomfortably alongside the increased expectations. The review also found that most firms had no formal AI usage policy and that many COLPs were unaware of the confidentiality implications of submitting client material to external platforms — a concern that intersected with the Upper Tribunal’s ruling in Munir v SSHD [2026] UKUT 81 (IAC) on AI and privilege waiver.
The combined effect is a regulatory environment where expectations are rising faster than many firms’ compliance infrastructure can keep pace. Dentons provides an important safeguard — not every failure will amount to misconduct — but the safeguard is cold comfort for firms whose systems cannot demonstrate a coherent, risk-based approach to compliance.
Practical Implications for Firms
For compliance teams, the decision creates both protection and obligation.
The seriousness threshold is a shield, not a sword. Firms cannot rely on Dentons to justify complacency about AML compliance. The case establishes that not every breach is misconduct, but it does not establish that AML breaches are inherently unserious. The remittal of the Principle 7 charge means that a fresh Tribunal panel may still find Dentons’ conduct to be sufficiently serious. Firms should not read this decision as permission to cut corners.
Systems and documentation remain critical. The new SRA sanctions guidance, combined with the OFSI strategy, makes clear that regulatory scrutiny will focus on whether the firm can demonstrate a coherent, risk-based approach. The SDT will assess seriousness by reference to the systems in place, the firm’s awareness of the risk, and the steps taken (or not taken) in response. A firm that identifies a client as high risk, receives intelligence suggesting serious criminality, and then relies on the assurances of a single non-regulated individual is in a weak position on seriousness regardless of the legal threshold.
Inadvertence is relevant but not determinative. The Tribunal’s finding that Dentons’ breach was “inadvertent and committed in good faith” was not challenged by the SRA on appeal. The Court of Appeal did not express a view on whether inadvertence should reduce seriousness. A fresh panel may take a different view — particularly given the facts that the firm had identified Client A as high risk at the outset and had received explicit intelligence about the missing $1 billion.
The “competent and reputable solicitors” test is now the standard. Paragraph 120 of the judgment provides the formulation: would competent and reputable solicitors consider this conduct sufficiently serious to be categorised as misconduct? This is not an abstract legal test — it is an evaluative judgment that the Tribunal must make by reference to the standards of the profession. Firms preparing for regulatory proceedings should frame their submissions around this test.
Dentons is a Court of Appeal authority and is binding on the SDT and the High Court. The seriousness threshold is now settled law unless and until the Supreme Court says otherwise. The SRA’s grammatical interpretation of Principle 7 has been decisively rejected.
Looking Forward
Three developments are worth monitoring.
First, the remitted hearing before a fresh SDT panel. The new panel must apply the seriousness threshold to the same facts and decide whether Dentons’ admitted AML breach crosses the line. The outcome will be the first practical application of the Dentons test and will signal how the Tribunal interprets “sufficient seriousness” in an AML context.
Second, the SRA’s response. The regulator may seek permission to appeal to the Supreme Court, although the Court of Appeal’s reasoning — grounded in longstanding common law principle and the internal coherence of the SRA’s own framework — is robust. Alternatively, the SRA may recalibrate its enforcement approach, focusing on cases where the seriousness of the breach is beyond argument.
Third, the interaction with the new sanctions guidance. The SRA’s February 2026 guidance positions itself as a benchmark against which firms’ conduct will be judged. A firm that falls short of the guidance’s expectations may face a stronger seriousness argument precisely because the guidance establishes what competent and reputable solicitors are expected to do. In this sense, the guidance and Dentons may prove complementary rather than contradictory: the guidance raises the bar for what counts as serious, while Dentons preserves the requirement that seriousness must be assessed.
