As is well known the general rule is that “without prejudice” negotiations which have previously taken place between the parties to a legal action are not admissible as evidence in Court. The reason for this, of course, is that it is in the public interest that people who are in dispute with each other should have the ability to speak entirely freely when trying to resolve the issues which are dividing them, without fear that what they say might later be used against them in court if they fail to reach a settlement. Exceptions to the general rule are few - there is for example an exception where the exclusion of what was communicated in without prejudice negotiations would act as a cloak for perjury or blackmail.
In an important case last February the Court of Appeal stressed the point that exceptions to the general rule are very limited. By a 2 to 1 majority the Court of Appeal held that the general rule is so important that “the policy of protecting without prejudice communications [is] stronger than the policy of providing the judge with every conceivable help to arrive at a just solution”. It therefore held that evidence of what was said in pre-trial “without prejudice” negotiations which had resulted in an out of court settlement was not admissible in a subsequent dispute as to what exactly had been agreed in that settlement. While all parties accepted the general rule and the reason for it, it had been argued that in the interests of justice there should be an exception where evidence of what had taken place in without prejudice negotiations was required only to help a judge decide the meaning of an out of court settlement which had resulted from the negotiations.
The case in point had nothing to do with employment law. However the principle it established was of such general importance, including importance in relation to out of court settlement of employment disputes, that an appeal to the Supreme Court was allowed.
The Supreme Court has now unanimously overruled the Court of Appeal.
In the case in question two companies, Oceanbulk and TMT, had entered into a written “Settlement Agreement” in relation to a disputed invoice. Prior to entering this agreement there were extensive discussions about the outstanding amount. Agreement was reached but subsequently Oceanbulk sued TMT claiming that it had defaulted on its obligations. The new dispute centred on the parties’ different interpretations of what a particular clause in the Settlement Agreement meant. TMT argued that the clause was the result of a particular line of negotiation. Although the negotiations were “without prejudice” TMT wanted to adduce details of them in evidence to demonstrate that its interpretation of the clause was in accordance with what both parties had intended it to mean. The High Court agreed with TMT but, as noted above, the Court of Appeal disagreed.
Now, at end October 2010, the Supreme Court has unanimously overruled the Court of Appeal and restored the original judgment of the High Court.
The Supreme Court has ruled that an “interpretation exception” should be recognised as an exception to the general “without prejudice” rule on the basis that “justice clearly demands it” – but was at pains to explain that the exception must not be extended “beyond evidence which is admissible in order to explain the factual matrix or surrounding circumstances to the court whose responsibility it is to construe the agreement…”.
In the Supreme Court Lord Phillips succinctly summed up the position as follows:-
“The principle to be derived from this appeal can be shortly stated. When construing a contract between two parties, evidence of facts within their common knowledge is admissible where those facts have a bearing on the meaning that should be given to the words of the contract. This is so even where the knowledge of those facts is conveyed by one party to the other in the course of negotiations that are conducted ‘without prejudice’.”
The lesson for employers and employees is clear: if a dispute goes to an employment tribunal it is only in very exceptional circumstances that the tribunal will hear evidence of what went on in “without prejudice” negotiations.
