(1) Where a contract has become impossible of performance or been otherwise frustrated, and the parties thereto have for that reason been discharged from the further performance of the contract, subsections (2) to (6) shall, subject to section 16, have effect in relation thereto.
(2) All sums paid or payable to any party in pursuance of the contract before the time when the parties were so discharged (in this Act referred to as "the time of discharge") shall, in the case of sums so paid, be recoverable from him as money received by him for the use of the party by whom the sums were paid, and, in the case of sums so payable, cease to be so payable:
Provided that, if the party to whom the sums were so paid or payable incurred expenses before the time of discharge in, or for the purpose of, the performance of the contract, the Court may, if it considers it just to do so having regard to all the circumstances of the case, allow him to retain or, as the case may be, recover the whole or any part of the sums so paid or payable, not being an amount in excess of the expenses so incurred.
(3) Where any party to the contract has, by reason of anything done by any other party thereto in, or for the purpose of, the performance of the contract, obtained a valuable benefit (other than a payment of money to which subsection (2) applies) before the time of discharge, there shall be recoverable from him by the said other party such sum (if any), not exceeding the value of the said benefit to the party obtaining it, as the Court considers just, having regard to all the circumstances of the case and, in particular-
(a) the amount of any expenses incurred before the time of discharge by the party benefited in, or for the purpose of, the performance of the contract, including any sums paid or payable by him to any other party in pursuance of the contract and retained or recoverable by that party under subsection (2); and
(b) the effect, in relation to the said benefit, of the circumstances giving rise to the frustration of the contract.
(4) In estimating, for the purposes of subsections (1) to (3), the amount of any expenses incurred by any party to the contract, the Court may, without prejudice to the generality of the said subsections, include such sum as appears to be reasonable in respect of overhead expenses and in respect of any work or services performed personally by the said party.
(5) In considering whether any sum ought to be recovered or retained under subsections (1) to (4) by any party to the contract the Court shall not take into account any sums which have, by reason of the circumstances giving rise to the frustration of the contract, become payable to that party under any contract of insurance unless there was an obligation to insure imposed by an express term of the frustrated contract or by or under any enactment.
(6) Where any person has assumed obligations under the contract in consideration of the conferring of a benefit by any other party to the contract upon any other person, whether a party to the contract or not, the Court may, if in all the circumstances of the case it considers it just to do so, treat for the purposes of subsection (3) any benefit so conferred as a benefit obtained by the person who has assumed the obligations as aforesaid.
(1) Section 15 shall apply to contracts whether made before or after the coming into force of this Act.
(2) Section 15 shall apply to contracts to which the Government is a party in like manner as to contracts between subjects.
(3) Where any contract to which section 15 applies contains any provisions which, upon the true construction of the contract, is intended to have effect in the event of circumstances arising which operate, or would but for the said provision operate, to frustrate the contract, or is intended to have effect whether those circumstances arise or not, the Court shall give effect to the said provision and shall only give effect to section 15 to such extent, if any, as appears to the Court to be consistent with the said provision.
(4) Where it appears to the Court that a part of any contract to which section 15 applies can properly be severed from the remainder of the contract, being a part wholly performed before the time of discharge, or so performed except for the payment in respect of that part of the contract of sums which are or can be ascertained under the contract, the Court shall treat that part of the contract as if it were a separate contract and had not been frustrated and shall treat section 15 as only applicable to the remainder of that contract.
(5) Section 15 shall not apply-
(a) to any charterparty, except a time charterparty or a charterparty by way of demise, or to any contract (other than a charterparty) or the corresponding provisions of any written law for the carriage of goods by sea;
(b) to any contract of insurance, save as is provided by subsection (5) thereof; or
(c) to any contract to which section 7 of the Sale of Goods Act 1893 of the United Kingdom [56 and 57 Vict.c.71] (which avoids contracts for the sale of specific goods which perish before the risk has passed to the buyer) or the corresponding provisions of any written law applies, or to any other contract for the sale, or for the sale and delivery, of specific goods, where the contract is frustrated by reason of the fact that the goods have perished.
