“The duty of the court is to construe the words used by the parties in the agreement. The courts do not have powers to interfere in contracts and impose terms arbitrarily, However, courts may imply a term in order to fill a gap left by the parties in the terms expressly agreed upon which fail to regulate their respective rights and inabilities in the situation that had arisen”.
“It is the duty of the court to state whether and when frustration has occurred; in other words, to determine the existence of frustration. Frustration occurs whenever the court recognizes that without default of either party a contractual obligation has become incapable of being performed”.
“Frustration occurs wherever the law recognizes that without default of either party, a contractual obligation has become incapable of being performed because the circumstances in which performance is called for would render it radically different from what was undertaken by the contract”
“We are inclined to accept the views of Viscount Simon and LordWright as being the correct statement of the law that the doctrine of frustration may in certain circumstances apply to a lease. We think that it may tantamount to injustice to deny a tenant the benefit of frustration in cases where, owing to circumstance of an intervening event or change of circumstances so fundamental as to be regarded by the law as striking at the root of the agreement, it has become impossible for the tenant to enjoy the fruits of his lease and at the same time to expect him on account of the abstract estate concept to honour his obligations under the lease. Such denial may also suffer injustice to a landlord who finds himself in the same situation as the landlord. ” Per BELLO, J.S.C. (Pp. 17-18,paras. G-C)
