In Jones & Ors v Lydon & Ors [2021] EWHC 2322 (Ch), the court confirmed that, where a series of communications is expressed to be made on a "without prejudice" basis, a party must express a clear intention to move the discussions onto an open footing before without prejudice privilege will cease to apply.
A simple failure to label a single communication in the series as "without prejudice", in circumstances where that communication clearly represents a continuation of the prior without prejudice discussions, will not constitute a sufficiently clear statement of intent for these purposes.
