More on the Horizon: Setting Aside Judgments Obtained by Fraud in England and Wales

Why It Matters

The rulings tighten the pathway for overturning fraudulent judgments, exposing corporations to significant liability and offering redress to victims of systemic scandals.

Key Takeaways

• Fraud can overturn judgments despite finality principle
• New, material evidence required; due‑diligence not mandatory
• Fraud need not be sole cause, just operative
• Separate claim needed; cannot use CPR 3.1(7) revocation
• Judgment may be set aside even if other party innocent

Pulse Analysis

The legal landscape surrounding fraudulent judgments in England and Wales is undergoing a subtle but consequential shift. While the doctrine traces back to the Court of Appeal’s 1956 Lazarus Estates ruling—‘fraud unravels everything’—the past two years have witnessed an unprecedented number of applications to unwind judgments tainted by deception. Central to this resurgence is the Post Office Horizon scandal, where hundreds of sub‑postmasters, including Lee Castleton, were wrongfully prosecuted based on faulty IT evidence. Castleton’s attempt to overturn a 2007 judgment and the associated bankruptcy order illustrates how legacy cases are being re‑examined under modern standards of fairness.

Recent appellate pronouncements have sharpened the criteria for success. The Supreme Court’s 2019 Takhar judgment confirmed that claimants need not demonstrate that the fraud was undiscoverable with reasonable diligence; instead, they must present new, material evidence that the fraudulent act was an operative cause of the original decision. The Royal Bank of Scotland and Finzi cases further stress that the evidence must be genuinely new and not merely a repackaging of information already available at trial. Importantly, the courts have ruled that a separate cause of action is required—CPR 3.1(7) cannot be invoked to simply revoke the order.

The practical ramifications are far‑reaching. If Castleton’s claim succeeds, it could trigger a cascade of challenges from other postmasters and parties who suffered similar injustices, compelling corporations to reassess risk management and settlement strategies. Legal practitioners will need to advise clients on gathering fresh evidence and navigating the high materiality hurdle, while insurers may see premium adjustments for fraud‑related coverage. Moreover, the willingness of higher courts to intervene underscores a broader judicial commitment to preserving the integrity of the legal process, even at the expense of finality. Stakeholders across the UK legal and corporate sectors should monitor the outcome closely.
