Receiving an adverse judgment in the lower courts can be an incredibly discouraging experience for any litigant. Whether you are an individual navigating a complex personal dispute or a corporate entity defending your commercial interests, a decision that feels fundamentally unjust can leave you questioning the efficacy of the English legal system.

However, it is vital to recognise a foundational reality of civil litigation: judges are human, and lower courts make errors. The English appellate framework exists precisely to serve as a corrective safety valve. Under Part 52 of the Civil Procedure Rules (CPR), the High Court and Court of Appeal possess the power to set aside, vary, or remit decisions that are “wrong” or “unjust because of a serious procedural or other irregularity.” Winning an appeal, however, requires far more than simply re-arguing the merits of your original case. It demands a meticulous, highly technical evaluation of where the lower court departed from established legal principles or procedural boundaries.

An example of this is today’s High Court decision handed down in the Chancery Division: Arran Coghlan & Anor v Lexlaw Limited [2026] EWHC 1512 (Ch). This case serves as a case study in appellate advocacy, demonstrating how holding a lower court judge strictly to the rules of procedure can dismantle an irregular judgment and revive litigation.

The Core Legal Threshold: When Can an Order Be Reversed?

It is critical to understand the legal standard an appellant must clear. An appellate court will not intervene merely because it might have weighed the evidence differently or arrived at a alternative conclusion within a permissible band of judicial discretion.To succeed, an appellant must typically show that the lower court judge committed:

An Error of Law: Misinterpreting a statute, misapplying a binding precedent, or introducing an incorrect legal test.

A Serious Procedural Irregularity: Violating the rules of natural justice, failing to give adequate reasons, or crucially deciding the application based on arguments or legal theories that were never properly raised or pleaded by the parties.

As the Coghlan v Lexlaw case illustrates, when a lower court judge wrongly attempts to rescue a poorly formulated case by straying outside the formal boundaries set by the parties’ statements of case, they commit a reversible error.

Case Study: Arran Coghlan & Anor v Lexlaw Limited

1. The Genesis of the Dispute

The background of the matter involves a highly contentious multi-layered legal dispute. The Appellant is a specialist firm of solicitors that had previously been instructed by the Respondents (Arran Coghlan and Claire Burgoyne) to act on their behalf in a substantial professional negligence action. Lexlaw had been retained under a hybrid Conditional Fee Agreement (CFA) dated 16 May 2018 having taking over conduct from a previous solicitors firm.

In February 2020, the Respondents terminated the CFA and instructed yet another new firm of solicitors, to take over the professional negligence claim. At the point of termination, Lexlaw asserted that substantial unpaid basic fees were due, alongside contingent success fees that would crystallise upon a “win”. To protect their commercial entitlement, Lexlaw exercised a solicitor’s lien over the client file and an equitable lien over the fruits of the litigation.

Crucially, Lexlaw issued a formal “Lien Letter” to BLM Law, who were the opposing solicitors in the underlying professional negligence case, putting them on clear notice of their equitable lien over any future settlement or judgment proceeds. The former clients retaliated by launching a wide-ranging lawsuit against Lexlaw (the “Lien Claim”). They asserted that merely protecting these legal costs through the Lien Letter amounted to a series of actionable wrongs, specifically alleging:

Alleged Defamation: This aspect has already been dismissed on a trial of this preliminary issue by High Court order of His Honour Judge Lewis who rejected such argument wholesale (see a summary of that decision on Legal Futures).

“It said nothing about the claimants’ character and would not have lowered or tended to lower the claimants in the estimation of right-thinking people generally,”  – His Honour Judge Lewis

Alleged Breach of Confidence: Disclosing confidential details (simply that monies would be payable on success). The judge noted that the claim was left entirely “unparticularised” and on the pleaded facts, it was impossible to understand how sending a standard Lien Letter could legally constitute a breach of the continuing duty of confidence.

Alleged Breach of Fiduciary Duty: Allegedly trying to compromise the clients’ position (of which there is no evidence). Similar to the confidentiality claim, the judge pointed out that the claimants provided no explanation or particulars showing how asserting a lien constituted a breach of fiduciary duty. Since the solicitor-client retainer had already been terminated when the letter was sent, the firm was no longer bound by an active fiduciary duty to advance the clients’ position. The judge found it impossible to see how trying to protect legally entitled fees amounted to an actionable breach of fiduciary duty on the face of the pleadings.

Alleged Breach of GDPR / Data Protection Act 2018: Unlawfully processing personal data through the publication of the letter (when it has been lawful to send such a Lien Letter for 200 years in England & Wales). The judge rejected the notion that the letter was an unlawful processing of personal data simply because the exact sum owed might be disputed. The lower court judge had allowed themselves to be swayed by unpleaded arguments regarding the financial accuracy of the lien amount. Mr Justice Edwin Johnson reaffirmed that a solicitor is legally entitled to write to a third party to assert an equitable lien, and flaws or disputes over the exact bill amount do not suddenly render the processing of data unlawful under the GDPR.

2. The Lower Court’s Overstep

Confronted with these improper allegations, and having emphatically won the preliminary issue that there was no defamation and given the Claimants wanted to continue to fight the remaining claims, Lexlaw took robust procedural action. Recognising that the claimants’ statements of case were legally deficient and structurally flawed, Lexlaw issued an application for summary judgment and/or to strike out the claims under CPR 3.4(2). They argued that the claims lacked any real prospect of success and were unparticularised.

The application came before His Honour Judge Monty KC in the County Court at Central London on May 29, 2025. In a surprising turn, HHJ Monty KC dismissed Lexlaw’s application. The judge found that the confidentiality, fiduciary duty, and GDPR elements of the claim were “reasonably arguable” for the purposes of avoiding summary judgment.

The judge reached this conclusion by relying on a nuanced interpretation of the CFA’s specific clauses regarding payment timelines and the validity of the underlying invoices – arguments that the claimants had not actually articulated or properly pleaded within their formal Particulars of Claim.

The Judge also appeared to be drawn to misleading arguments by Coghlan’s counsel that if the amount in the Lien Letter was wrong then this would amount to wrongdoing. This superficial analysis fails to recgnise the very existence of the Solicitors Act 1974, in particular with reference to assessment of solicitors’ bills, which means that no solicitor’s bill can ever be a liquidated debt and is never certain in sum and by a procedure of assessment can be reduced, even down to nil. Hence a solicitor’s bill can never form the basis of a statutory demand, bankruptcy or winding-up petiiton. Furthermore, the readership of the Lien Letter were solicitors who would always be cognisant of the 1974 Act and its potential implication on the potential amount of the lien.

3. The Turning Point in the High Court

Lexlaw refused to accept this flawed decision. They successfully obtained permission to appeal, bringing the matter before Mr Justice Edwin Johnson in the High Court (Chancery Division). In a rigorous judgment handed down on June 18, 2026, Mr Justice Edwin Johnson overturned the lower court’s refusal to grant summary judgment. The High Court identified a profound procedural error in how the County Court judge had treated the statements of case:

Judges Cannot Decide Cases on Unpleaded Grounds: The High Court observed that the confidentiality and fiduciary duty claims, as originally written in the formal Particulars of Claim, were left entirely unparticularised. It was accepted as standard practice that a solicitor exercising a lien is legally entitled to write to a third party to assert it. The lower court judge had essentially constructed a hypothetical case based on an unpleaded interpretation of the CFA to find the claim arguable. Mr Justice Edwin Johnson stated:

“The Judge made his decision to refuse the grant of summary judgment… on the basis of a case which was not pleaded… In my view, the Judge was not entitled to take this course.”

Witness Statements are Not Statements of Case: The Respondents attempted to argue that any gaps in their pleadings were filled by the narrative evidence contained in the client’s witness statements. The High Court emphatically rejected this. Witness statements exist solely to identify relevant matters of fact; they cannot act as a substitute for formal, legally binding pleadings.

4. The Result

Because the County Court judge had detached his ruling from the actual statements of case, the High Court ruled the order unsustainable. Rather than allowing a procedurally compromised decision to stand, the High Court set aside the lower court order and remitted the entire summary judgment application back to the Central London County Court. This mandatory remittal forces the lower court to hear the application properly alongside the claimants’ lagging draft amendment applications.

Key Takeaways for Litigants Facing an Unfair Judgment

This second published decision in the Coghlan v Lexlaw litigation battle highlights critical rules that apply to any litigant evaluating whether to launch an appeal:

A. Pleadings Form the Boundaries of a Lawsuit

In English civil procedure, a court is strictly bound by the statements of case (the Particulars of Claim and Defence). A judge cannot act as a rogue advocate. If an opponent has a weak case, and the judge “saves” them by dreaming up a legal theory that was never formally pleaded, that judgment is highly vulnerable to being struck down on appeal.

B. Gaps Cannot Simply Be “Patched Over” Later

You cannot initiate a vague claim via a Part 7 Claim Form and hope to retroactively inject substance into it via witness statements or oral arguments during a interim hearing. Appellate courts demand precision. If the lower court overlooks a fatal lack of detail in your opponent’s case, an appeal is your mechanism to enforce adherance to civil procedure rules.

C. Acting Swiftly is Paramount

The window to appeal an interim order or a final judgment is unforgivingly brief (often just 21 days under CPR 52.12 unless the lower court specifies otherwise). Meticulous analysis must begin the moment the judgment is handed down.

Strategy and Reality: Is an Appeal Right for You?

Appealing a judicial error is a highly strategic endeavor. It requires evaluating the commercial reality of your position:

The Cost-Benefit Analysis: Grounding an appeal requires specialized appellate counsel who can isolate exact errors of law or procedure. You must balance the costs of the appeal against the financial or reputational impact of letting a flawed lower court order stand.

Correcting the Record: Beyond the immediate financial stakes, allowing an erroneous judgment to remain unchallenged can create damaging judicial precedents for your business operations or personal standing.
