Panduan turut diberikan dalam kes Asiapools (M) Sdn Bhd v IJM Construction Sdn Bhd [2010] 3 MLJ 7 yang memutuskan bahawa – [50] In construing a written contract, like the present case at hand, the professed object of the court is quite simple. It is to discover the mutual intention of the parties (Pioneer Shipping Ltd and others v BTP Tioxide Ltd and International Fina Services AG, Katrina Shipping Ltd and Tonen, Tanker Kabushiki Kaisha, (the ‘Fina Samco’) [1995] 2 Lloyd’s Rep 344 (CA) at p 350). And the intention of the parties must be ascertained from the documents itself. Thus, the parties themselves cannot give direct evidence to show that their intention were at variance with the provisions of the contract document (Prenn v Simmonds [1971] 1 WLR 1382 (HL) at p 1385; Hyundai Merchant Marine Co Ltd v Gesuri Chattering Co Ltd, (the ‘Peonia’) [1991] 1 Lloyd’s Rep 100 (CA) at p 102; British Movietonews Ld v London and District Cinemas Ld [1952] AC 166 (HL); and Zoan v Rouamba [2000] 1 WLR 1509 (CA) at p 1523). The task of the court is quite simple. It is to construe the contractual term without any preconception as to what the parties intended (Pagnan SpA v Tradax Ocean Transportation SA [1987] 1 All ER 81 at p 88, which was affirmed on appeal vide [1987] 3 All ER 565). [51] When the minds of the parties are expressed in an unambiguous manner, the principles of construction which are at best only a guide in the search for the intention of the parties cannot be relied upon to override the declared intention of the parties unequivocally expressed in the contract document (K Appukuttan Panicker and another v SKRAKR Athappa Chettiar AIR 1966 Kerala 303). And where the intention of the parties is clear from the language which they have used in the agreement, like the present case at hand, and the words contained therein are clear and unambiguous, there is no scope for drawing upon hypothetical considerations or supposed intentions of the parties (The Union of India v Kishorilal Gupta and Bros AIR 1959 Supreme Court 1362). According to the case of James Miller and Partners Ltd v Whitworth Street Estates (Manchester) Ltd [1970] AC 583; [1970] 1 All ER 796 (HL), once a contract has been considered it must be interpreted without reference to pre-contractual negotiations or subsequent dealing between the parties. The reason for this approach is easily discernible. It is purely to preserve the certainty given by written contracts.
