(i) As a matter of objective fact, the company executed the deed of guarantee solely in its own right.
(ii) The question of capacity in which the company executed the deed of guarantee and indemnity is a matter to be determined objectively and not on the basis of the subjective intentions of the parties; and is a matter of construction to be decided by reference to all the circumstances in the case.
(iii) There is no presumption that a company is acting in any capacity other than on its own behalf when it contracts with another party and, therefore, no rule that a company is, without more, presumed to be acting in capacities other than its personal right when it contracts with another company.
(iv) Where a company known to have only acted in the past in a trustee capacity, claims to have acted in its own right, and in so doing to have given a worthless guarantee, that company faces an evidential burden if it is to establish that a contract which defies commercial logic in such a manner is one which has been accepted on that basis by the other party to the contract.
(v) Once it is accepted that extrinsic evidence must be adduced to resolve a factual question, ie, in what capacity a party entered into a certain contract, there is no logical reason why that evidence should be confined either temporally, or as to oral or documentary evidence. The only restriction which needs to be imposed is that which encompasses the traditional rules concerning the admissibility of evidence.
(vi) Extrinsic evidence, when led to establish the capacity in which a party has executed a contract, is not being led in order to construct the terms of the contract. Such evidence was not concerned with the actual intentions of the parties as to the meaning of the written terms of the contract but to a matter which was in common contemplation but was otherwise embodied in the terms of the written agreement and was, therefore, admissible.
(vii) A conclusion that the company did not execute the deed of guarantee and indemnity as trustee, but only personally, would not be one which would destroy the effect of the deed, although the efficacy of the deed as a source of funds in the event of default but the borrower would be limited unless the company later came into funds in its own account.
