The High Court has said the regulator cannot force solicitors to hand over privileged documents. The SRA is now taking the question straight to the top court, and the answer will shape how every solicitor is investigated.

Legal professional privilege is one of the first concepts you meet as a law student, and one of the last you fully understand. A new case shows exactly why. The question is simple: when the regulator investigates a solicitor, can it demand documents that belong to the client and are protected by privilege?

The High Court has said no. The Solicitors Regulation Authority has said it will not leave it there.

The case is Carter-Ruck Solicitors and another v Solicitors Regulation Authority [2026] EWHC 2416 (KB). It arose from an SRA investigation that began in September 2023 into the media law firm Carter-Ruck and one of its partners, over work they did for the businessman Mohamed Amersi.

Carter-Ruck had acted for Mr Amersi in a defamation claim against a former MP, which the High Court struck out in June 2023. The Court of Appeal refused permission to appeal. The former MP then said she would complain to the SRA about the firm's conduct. Carter-Ruck strongly rejected any suggestion of misconduct, and Carter-Ruck, the partner and Mr Amersi all deny any wrongdoing. The SRA's investigation has not produced any finding against them.

The SRA served three notices under section 44B of the Solicitors Act 1974, a power that allows it to require regulated persons to produce documents and information. Some of the material it wanted was protected by Mr Amersi's legal professional privilege. He declined to waive it.

Carter-Ruck and Mr Amersi asked the court for a declaration that section 44B does not entitle the SRA to compel production of privileged material. The SRA asked for the opposite declaration.

Mr Justice Butcher ruled in favour of Carter-Ruck. He held that the SRA cannot use section 44B to require production of material subject to a client's privilege where the client has not waived it.

The reasoning matters, because it applies far beyond this dispute. Legal professional privilege is not just another confidentiality duty. It is a fundamental right, and the court said it can only be overridden by express statutory wording or by necessary implication. Section 44B contains no express override, and the judge was not persuaded that the SRA had cleared the high bar of necessary implication.

The SRA argued that its statutory purpose would be frustrated if it could not see privileged documents. The judge accepted that the power might be impeded, but not that it would be stultified, because there would still be many cases where the SRA could investigate effectively. He also observed that the SRA's own position had at times been equivocal, which was not enough to override the right.

One other point is worth knowing. The High Court was bound by the Court of Appeal's earlier decision in the Sports Direct case, which shaped how it approached the question.

The SRA has said the ruling could hamper investigations, and that the point is important to the effective regulation of the profession. The High Court has granted it permission to appeal and issued a leapfrog certificate, which allows it to seek permission directly from the Supreme Court rather than going through the Court of Appeal first.

A leapfrog certificate is only available where a case raises a point of law of general public importance, and the trial judge recognised that this one does. The SRA must now ask the Supreme Court for permission. If permission is refused, it can still go to the Court of Appeal.

The practical stakes are significant. At the time of one commentator's analysis, the SRA was handling investigations linked to 1,844 reports of potential misconduct, and some of those depend on access to material that the High Court says it cannot compel. Investigations into abusive litigation are an obvious example. The Carter-Ruck investigation itself began in that area.

There is a tension here that is worth understanding rather than picking a side on. Clients are protected, because privilege belongs to them and cannot be taken from them by a regulator without their agreement. At the same time, a regulator that cannot see the documents may struggle to establish what a solicitor did on a client's behalf. Mr Amersi's own response to the appeal was that privilege properly belongs to the client, while the SRA says the question goes to the effective regulation of the profession.

If you are a paralegal or trainee, it is easy to treat privilege as a topic for the exam. This case shows it as a live constraint on how regulators work.

Three practical lessons come out of it. First, privilege belongs to the client, not to you or your firm, and only the client can waive it. Second, you cannot assume a regulator's wide investigative powers automatically reach privileged material, because the courts require clear words to cut across a fundamental right. Third, the position may change again. The Supreme Court may decide differently, and Parliament can always legislate to give the SRA the power expressly.

In an interview, this is a strong example of how regulation and fundamental rights collide. You can explain the High Court's reasoning, identify the SRA's counter argument, and note that the final answer is still to come.

For now, the law is that a client's privilege stands unless the client waives it, even when a regulator is asking. Whether that remains true is a matter for the Supreme Court, if it grants permission. Whatever it decides, it will tell every solicitor how much of their client's confidence they can be forced to disclose to their own regulator.
