Principle Statement

It is settled law that where parties are ad idem on the terms of a contract, the function of the court is to give effect to the terms without more as it is the duty of the court to give effect to the intention of the parties. In the instant case, the contract is in writing, exhibit C, and the court is faced with the construction of clause 8(C) supra. The question that consequently arises is not what the parties have intended to do by entering into exhibit C but what is the meaning of the words as used in clause 8(C).
