“(1) Subject to the remaining sub-clauses of this clause 10 neither the Seller nor the Buyer shall be responsible for any failure to fulfil their respective obligations under this Agreement (other than payment of money due) if fulfilment has been delayed, interfered with, curtailed or prevented by: (a) Act of God, fire, any consequences of war, invasion, act of foreign enemy, hostilities, (whether war has been declared or not), civil war, rebellion, revolution or insurrection; (b) Any strike, lock-out or labour dispute whether or not the Seller, its suppliers or the Buyer as the case may be, are party thereto or would be able to influence or procure the settlement thereof; (c) Tropical storm, hurricane, earthquake, flooding resulting from heavy rainfall or any other natural disaster; (d) Any curtailment, failure or cessation of supplies of crude oil or refined petroleum products from any of the Seller or its suppliers’ sources of supply or Seller’s leased storage facilities on St Croix, USVI, which are in fact sources of supply or storage for the purposes of this present Agreement; (e) Any compliance with any order, demand or request of any international, national, port of transportation, local or other authority or agency relating to health or safety regulations; and (f) Any other circumstances which are not within the reasonable control of the Buyer or the Seller or its suppliers. (2) If by reason of any causes referred to in paragraph (1) (a) to (c), (d), (e) and (f) of this clause, either the availability from any of the Seller’s or its suppliers’ sources of supply of crude oil or refined petroleum products or the Seller’s leased storage facilities on St Croix, whether deliverable under this Agreement or not, or the normal means of transport of such crude oil or products, is delayed, hindered, interfered with, curtailed or prevented, then the Seller shall be at liberty to withhold, reduce or suspend the deliveries hereunder to such extent as the Seller may in its absolute discretion think fit and the Seller shall not be bound to purchase or otherwise make good shortages resulting from such causes. (3) A request for Performance Relief shall be made in writing and shall specify the reason for the request with supporting documents. In addition to the foregoing, in all requests for Performance Relief the nonperforming party must prove that the party took all reasonable steps to minimise delay or damages caused by foreseeable events, that the party substantially fulfilled all non-excused obligations, and that the other party was timely notified of the likelihood or actual occurrence of an event described in this clause 10. (4) For the purpose of this clause, the Seller's suppliers shall mean any body or person by whom, directly or indirectly the refined petroleum products to be purchased and sold hereunder are supplied, stored and/or transported to the Seller. (5) The Buyer shall be free to purchase from other suppliers on its account, any deficiencies caused by the operation of this clause.”
“The waiver in issue in this case is one arising from a conscious business decision made by a corporation engaged in business across states, territories and nationalities … to continue to supply products to a major statutory corporation with which it had contracted, notwithstanding a circumstance which entitled it to terminate the contract and relieve itself of its obligation to supply the agreed products … at the agreed price. In so doing, it jettisoned the alternative course of action … when the opportunity to do so presented itself. There can be no argument that in making this election the [Seller] was fully aware of the facts giving rise to its right to continue to supply the agreed products to the [Buyer] under the contract or to terminate the contract. Although the point was argued by the [Seller], the trial judge found as a fact that the [Seller] had clearly and unequivocally communicated its choice to the [Buyer] (by words and deeds) not to exercise the right to terminate which had become available to it upon the closure of the Hovensa storage facility.”
“in a situation where a person is entitled to alternative rights inconsistent with one another. If he has knowledge of the facts which give rise in law to these alternative rights and acts in a manner which is consistent only with his having chosen to rely on one of them, the law holds him to his choice even though he was unaware that this would be the legal consequence of what he did.”
“[Election] generally requires knowledge of the facts giving rise to the choice on the part of the party electing, and knowledge of the choice having been made on the part of the other party. Those are the conditions which make the doctrine mutually fair. It typically arises where the parties to a contract have to know where they stand. Thus the choice has either to be communicated unequivocally by the party electing to the other party or else the objective circumstances have to be such that the effluxion of time by itself constitutes that communication. Since the election is the choice of the party electing, it is his conduct which is decisive. Once made the election is final and irrevocable.”
“when ordering repayment the House is unravelling the practical consequences of orders made by the courts below and duly carried out by the unsuccessful party. The result of the appeal to this House was that, to the extent indicated, orders made in the courts below should not have been made. This result could, in some cases, be an idle exercise unless the House were able to make consequential orders which achieve, as nearly as is reasonably practicable, the restitution which this result requires. This requires that the House should have power to order repayment of money paid over pursuant to an order which is subsequently set aside. It also requires that in suitable cases the House should have power to award interest on amounts ordered to be repaid. Otherwise the unravelling would be partial only. This power seems to me to fall squarely within that range of powers which are necessarily implicit if a court of law possessed of appellate functions is to carry out its prescribed functions properly. It is, as such, a power derived from what is usually referred to as the inherent jurisdiction of the court. It is a power equally possessed by the Court of Appeal consequential upon orders made by it. The only surprising aspect of this power is that its existence has not previously arisen for decision.”
“it was in the power, and it became the duty, of the court at Hong Kong to do everything, and to make every order which was fairly and properly consequential upon the reversal of the original judgment by this tribunal.”
“[the petitioners] will by reason of an act of the court have paid a sum which it is now ascertained was ordered to be paid by mistake and wrongfully. They will recover that sum after the lapse of a considerable time, but they will recover it without the ordinary fruits which are derived from the enjoyment of money. On the other hand, those fruits will have been enjoyed, or may have been enjoyed, by the person who by mistake and by wrong obtained possession of the money under a judgment which has been reversed. So far, therefore, as principle is concerned, their Lordships have no doubt or hesitation in saying that injustice will be done to the petitioners, and that the perfect judicial determination which it must be the object of all courts to arrive at, will not have been arrived at unless the persons who have had their money improperly taken from them have the money restored to them, with interest, during the time that the money has been withheld.”
“This survey shows that the principle on which the courts have for centuries acted is that when an erroneous judgment or order is overturned, whether by means of appeal or by any other procedure, the court will achieve a just result by requiring anything that has been taken from him by the other party by virtue of the wrong decision to be restored. … The principle is, as it was in the reign of the first Elizabeth (Eyre v Woodfine (1590) Cro Eliz 278), one of restitution or restoration. The court is seeking to restore to one party what it has wrongly taken from him and given to the other. It does not seek to restore the successful party to his former position by awarding damages to compensate him for loss flowing from the erroneous judgment or order.”
“It is then settled that a successful appellant can compel the respondent to restore all benefits gained through the judgment which has been reversed. The appellant has a right of ‘restitution’ of money paid by him, and to property transferred which is still in the defendant's possession, under a judgment now reversed.”
