If, on the other hand, a party is referring to extrinsic evidence in the form of pre-contractual negotiations as an aid to interpret a particular clause or expression used in the contractual document, that would be allowed. That would not run afoul of the parol evidence rule (see s 94(f) of the EA) or the “entire agreement” clause in clause 21 of the Loan Agreement (see Lee Chee Wei at [41]). However, it is important to bear in mind that the reference to the pre-contractual negotiations must not only satisfy the three requirements for the admission of extrinsic evidence as set out in Zurich Insurance, but it is also limited to assisting in the interpretation of a term, a clause, a phrase, a sentence or some other expression, that the parties have used in the contractual document. Hence, the party seeking to rely on the extrinsic evidence in the form of pre-contractual negotiations for the purpose of interpretation must be clear in identifying the particular term, clause, phrase, sentence or expression, that the extrinsic evidence seeks to elucidate in terms of the meaning to be ascribed to it (see Sembcorp Marine Ltd v PPL Holdings Pte Ltd and another and another appeal [2013] 4 SLR 193 at [72]–[74]). Otherwise, the reference to the pre-contractual negotiations would often stray into attempts to persuade the court to re-write the contract by the introduction of terms that are not found in the written document (see Zurich Insurance at [122]).
