If you've spent any time in a commercial dispute, you've seen the words. At the top of a letter, in the subject line of an email, sometimes apparently at random in correspondence that doesn't obviously involve any negotiation at all. Without Prejudice.

It sounds authoritative. It sounds protective. And in the right circumstances, it is. In the wrong circumstances — which is a significant proportion of the circumstances in which it actually gets used — it means nothing at all.

### Where the confusion starts

Litigants in person, and occasionally people who should know better, attach "Without Prejudice" to correspondence because it sounds legal. It has the weight of formality about it. The assumption is that labelling a document without prejudice provides some kind of protection — that it can't be used against them, or that it demonstrates they're approaching things sensibly.

None of that is what without prejudice actually means. Putting the words at the top of an email does not make the email without prejudice. The label is not the rule.

### What it actually means

The without prejudice rule is a rule of evidence. It protects from disclosure, in litigation, genuine attempts to negotiate a settlement of a dispute. The rationale is that parties should be able to explore compromise without fear that their concessions will be used against them if negotiations fail and the matter proceeds to trial.

The key word is genuine. The protection applies to communications that are a genuine attempt to settle — offers, counter-offers, admissions made in the course of negotiation, proposals for resolution. It does not apply simply because the words appear on the document.

A letter that makes a demand, sets out a legal position, or threatens proceedings is not without prejudice merely because it says it is. A letter that contains a genuine offer of settlement, even if it doesn't use the words, may well be protected. The substance governs, not the label.

### What it doesn't cover

The without prejudice rule is subject to exceptions that are worth knowing.

It doesn't protect communications where there is no dispute in existence, or no dispute that the parties are genuinely trying to resolve. Correspondence before a dispute has crystallised, or in relation to matters that aren't actually in contention between the parties, doesn't attract the protection.

It doesn't cover unambiguous impropriety. A communication that contains a threat, a misrepresentation, or an attempt to obtain an improper advantage can be admitted in evidence notwithstanding the without prejudice label.

And it doesn't prevent the court from seeing the correspondence for the limited purpose of establishing that a settlement was reached — or, in some circumstances, that it wasn't. Without prejudice communications can be admitted to prove the existence and terms of an agreement. The protection is against using the content of negotiations against a party; it doesn't extend to concealing the fact that a concluded agreement exists.

### Without prejudice save as to costs

This is a distinct and important variation. A without prejudice save as to costs communication — most commonly a Part 36 offer, which I've written about separately — is protected from disclosure during the substantive hearing but can be referred to when the court deals with costs after judgment. It is specifically designed to allow parties to make offers that influence the costs consequences of litigation without affecting the merits hearing.

Understanding the difference between without prejudice and without prejudice save as to costs is practically important. They're not interchangeable, and using one when you mean the other can have unintended consequences.

### The practical position

If you're in a commercial dispute and you want to make a genuine offer of settlement that is protected from use at trial, the communication needs to be a genuine attempt to negotiate — the label alone won't do it. If you receive a without prejudice communication, the question of whether it's actually protected depends on its substance, not its heading.

And if you're a litigant in person adding the words to correspondence because they sound impressive — they don't. They just tell the other side that you've heard the phrase without fully understanding it.

Without prejudice communications in live disputes need to be handled carefully — getting it wrong can have real consequences for your position. If you want to talk through how to approach a settlement negotiation, I'm happy to help you think it through.
