“the replaced cable found corroded and with broken wires out of limits.”
“Would a prudent owner have required that the defect should be made good before sending his ship to sea, had he known of it. If he would the ship was not seaworthy.”
“Would a prudent operator of an aircraft have required that the defect should be made good before permitting the aircraft to fly, had he known of it. If he would the aircraft was not airworthy.”
“Conclusive Proof Delivery by Lessee to Lessor of the Certificate of Acceptance will be conclusive proof as between Lessor and Lessee that Lessee has examined and investigated the aircraft, that the aircraft and the aircraft documents are satisfactory to lessee and that Lessee has irrevocably and unconditionally accepted the aircraft for lease hereunder without any reservations whatsoever (except for any discrepancies which may be noted in the certificate of acceptance).”
"…frustration occurs whenever the law recognises 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 a thing radically different from that which was undertaken by the contract. Non haec in foedera veni. It was not this that I promised to do."[1] 85. Lord Simon said: "
“111. In my judgment, the application of the doctrine of frustration requires a multi-factorial approach. Among the factors which have to be considered are the terms of the contract itself, its matrix or context, the parties' knowledge, expectations, assumptions and contemplations, in particular as to risk, as at the time of contract, at any rate so far as these can be ascribed mutually and objectively, and then the nature of the supervening event, and the parties' reasonable and objectively ascertainable calculations as to the possibilities of future performance in the new circumstances. Since the subject matter of the doctrine of frustration is contract, and contracts are about the allocation of risk, and since the allocation and assumption of risk is not simply a matter of express or implied provision but may also depend on less easily defined matters such as "the contemplation of the parties", the application of the doctrine can often be a difficult one. In such circumstances, the test of "radically different" is important: it tells us that the doctrine is not to be lightly invoked; that mere incidence of expense or delay or onerousness is not sufficient; and that there has to be as it were a break in identity between the contract as provided for and contemplated and its performance in the new circumstances. 112. What the "radically different" test, however, does not in itself tell us is that the doctrine is one of justice, as has been repeatedly affirmed on the highest authority. Ultimately the application of the test cannot safely be performed without the consequences of the decision, one way or the other, being measured against the demands of justice. Part of that calculation is the consideration that the frustration of a contract may well mean that the contractual allocation of risk is reversed. A time charter is a good example. Under such a charter, the risk of delay, subject to express provision for the cessation of hire under an off-hire clause, is absolutely on the charterer. If, however, a charter is frustrated by delay, then the risk of delay is wholly reversed: the delay now falls on the owner. If the provisions of a contract in their literal sense are to make way for the absolving effect of frustration, then that must, in my judgment, be in the interests of justice and not against those interests. Since the purpose of the doctrine is to do justice, then its application cannot be divorced from considerations of justice. Those considerations are among the most important of the factors which a tribunal has to bear in mind.”
