To begin with, and as already observed, when faced with an action requiring the interpretation of a written document, our role is to carefully analyze it to determine the true intentions of the parties involved. That exercise should not admit of external factors that will cloud the same, but we must limit ourselves to the four corners of the agreement. Indeed, we should not be seen to be re-writing the parties’ agreement for them, that will be an irregular usurpation. As observed by Justice Francois in the case of Allan Sugar (Products) Ltd v Ghana Export Co Ltd [1982-83] GLR 922: “It is no function of the court to rewrite an agreement for the parties by inserting terms that would have been beneficial but were overlooked especially when such an interpolation would amount to an interference with a third party’s bargain.”
