When “without prejudice” correspondence attacks! (Morris v Williams) – Lexology
Understanding the Limits of Without Prejudice Correspondence
The High Court’s decision in Morris v Williams [2025] EWHC 218 (KB) serves as an important reminder that even correspondence marked “without prejudice save as to costs” are not immune from disclosure where the content falls within an established exception to the general rule.
Background: A Dispute Over Fundamental Dishonesty
The case arose from a road traffic accident, where the defendant alleged that the claimant had acted in a fundamentally dishonest manner. In the course of negotiations, the claimant’s solicitors made a Calderbank offer in a letter marked “without prejudice save as to costs”. Crucially, the letter included an offer by the claimant not only to pay the defendant a sum of money, but also to admit that he had been “fundamentally dishonest in respect of some of the representations made in respect of this claim”. However, this admission was expressly conditional on the creation of a non-disclosure agreement to prevent any third-party disclosure.
The defendant rejected the offer and subsequently sought to adduce the letter into evidence. The central argument was that the admission of dishonesty constituted “unambiguous impropriety” a recognised exception to the without prejudice rule.
The Court’s Decision: Crossing the Line into Impropriety
District Judge Dodsworth, sitting at the High Court in Sunderland, considered the principles underpinning the without prejudice doctrine and its exceptions. Citing Merrill Lynch v Raffa [2001] ILPr 31, he concluded that the claimant’s letter “crossed the line” into unambiguous impropriety. At paragraph 21, the judge explained:
“This is an example where the public policy arguments in favour of litigating disputes with full disclosure trump the policy argument in allowing parties to speak candidly and with protection of the contents of the discussions, to encourage settlements.”
The letter, while styled in settlement terms, amounted to an express admission of dishonesty. The attempt to confine that admission within a confidentiality agreement did not prevent the court from scrutinising the substance of the communication.
Implications for Litigants and Legal Advisers
This judgment underscores the need for extreme care when drafting without prejudice correspondence – particularly where it involves admissions, concessions, or factual assertions that might later be relied upon in open court.
Had the letter merely acknowledged the potential evidential difficulties with parts of the claim, or stated that the claimant’s case could be perceived as exaggerated, it is likely that it would have remained protected. However, the explicit admission of dishonesty, although conditional, rendered the letter admissible and ultimately detrimental to the claimant’s case.
Key Takeaways for Practitioners
- The “without prejudice” label does not offer blanket protection. Content matters.
- The “unambiguous impropriety” exception can apply where a party seeks to use the cloak of confidentiality to admit to misconduct.
- Conditional admissions especially those hinging on non-disclosure does not necessarily shield correspondence from judicial scrutiny.
Practitioners should take particular care when negotiating in cases involving allegations of dishonesty, fraud, or misconduct.
Conclusion
Morris v Williams is a cautionary tale about the limits of confidentiality in legal negotiations. It highlights the tension between encouraging candid settlement discussions and preserving the integrity of the litigation process. For litigants or legal advisers, the message is clear: when in doubt, temper the content of without prejudice letters and avoid any language that could later be construed as an admission crossing the threshold of impropriety.
