| ||1. Hardship defined
This Article defines hardship as a situation where the occurrence of events fundamentally alters the equilibrium of the contract, provided that those events meet the requirements which are laid down in sub-paragraphs (a) to (d).
2. Fundamental alteration of equilibrium of the contract
Since the general principle is that a change in circumstances does not affect the obligation to perform (see Article 6.2.1), it follows that hardship may not be invoked unless the alteration of the equilibrium of the contract is fundamental. Whether an alteration is “fundamental” in a given case will of course depend upon the circumstances.
1. In September 1989 A, a dealer in electronic goods situated in the former German Democratic Republic, purchases stocks from B, situated in country X, also a former socialist country. The goods are to be delivered by B in December 1990. In November 1990, A informs B that the goods are no longer of any use to it, claiming that after the unification of the German Democratic Republic and the Federal Republic of Germany and the opening of the former German Democratic Republic to the international market there is no longer any market for such goods imported from country X. Unless the circumstances indicate otherwise, A is entitled to invoke hardship.
a. Increase in cost of performance
In practice a fundamental alteration in the equilibrium of the contract may manifest itself in two different but related ways. The first is characterised by a substantial increase in the cost for one party of performing its obligation. This party will normally be the one who is to perform the non-monetary obligation. The substantial increase in the cost may, for instance, be due to a dramatic rise in the price of the raw materials necessary for the production of the goods or the rendering of the services, or to the introduction of new safety regulations requiring far more expensive production procedures.
b. Decrease in value of the performance received by one party
The second manifestation of hardship is characterised by a substantial decrease in the value of the performance received by one party, including cases where the performance no longer has any value at all for the receiving party. The performance may relate either to a monetary or a non-monetary obligation. The substantial decrease in the value or the total loss of any value of the performance may be due either to drastic changes in market conditions (e.g. the effect of a dramatic increase in inflation on a contractually agreed price) or the frustration of the purpose for which the performance was required (e.g. the effect of a prohibition to build on a plot of land acquired for building purposes or the effect of an export embargo on goods acquired with a view to their subsequent export).
Naturally the decrease in value of the performance must be capable of objective measurement: a mere change in the personal opinion of the receiving party as to the value of the performance is of no relevance. As to the frustration of the purpose of the performance, this can only be taken into account when the purpose in question was known or at least ought to have been known to both parties.
3. Additional requirements for hardship to arise
a. Events occur or become known after conclusion of the contract
According to sub-paragraph (a) of this Article, the events causing hardship must take place or become known to the disadvantaged party after the conclusion of the contract. If that party had known of those events when entering into the contract, it would have been able to take them into account at that time. In such a case that party may not subsequently rely on hardship.
b. Events could not reasonably have been taken into account by disadvantaged party
Even if the change in circumstances occurs after the conclusion of the contract, sub-paragraph (b) of this Article makes it clear that such circumstances cannot cause hardship if they could reasonably have been taken into account by the disadvantaged party at the time the contract was concluded.
2. A agrees to supply B with crude oil from country X at a fixed price for the next five years, notwithstanding the acute political tensions in the region. Two years after the conclusion of the contract, a war erupts between contending factions in neighbouring countries. The war results in a world energy crisis and oil prices increase drastically. A is not entitled to invoke hardship because such a rise in the price of crude oil was not unforeseeable.
Sometimes the change in circumstances is gradual, but the final result of those gradual changes may constitute a case of hardship. If the change began before the contract was concluded, hardship will not arise unless the pace of change increases dramatically during the life of the contract.
3. In a sales contract between A and B the price is expressed in the currency of country X, a currency the value of which was already depreciating slowly against other major currencies before the conclusion of the contract. One month thereafter a political crisis in country X leads to a massive devaluation of its currency of the order of 80%. Unless the circumstances indicate otherwise, this constitutes a case of hardship, since such a dramatic acceleration of the loss of value of the currency of country X was not foreseeable.
c. Events beyond the control of disadvantaged party
Under sub-paragraph (c) of this Article a case of hardship can only arise if the events causing the hardship are beyond the control of the disadvantaged party.
d. Risks must not have been assumed by disadvantaged party
Under sub-paragraph (d) there can be no hardship if the disadvantaged party had assumed the risk of the change in circumstances. The word “assumption” makes it clear that the risks need not have been taken over expressly, but that this may follow from the very nature of the contract. A party who enters into a speculative transaction is deemed to accept a certain degree of risk, even though it may not have been fully aware of that risk at the time it entered into the contract.
4. A, an insurance company specialised in the insurance of shipping risks, requests an additional premium from those of its customers who have contracts which include the risks of war and civil insurrection, so as to meet the substantially greater risk to which it is exposed following upon the simultaneous outbreak of war and civil insurrection in three countries in the same region. A is not entitled to such an adaptation of the contract, since by the war and civil insurrection clauses insurance companies assume these risks even if three countries are affected at the same time.
4. Hardship relevant only to performance not yet rendered
By its very nature hardship can only become of relevance with respect to performances still to be rendered: once a party has performed, it is no longer entitled to invoke a substantial increase in the costs of its performance or a substantial decrease in the value of the performance it receives as a consequence of a change in circum¬stances which occurs after such performance.
If the fundamental alteration in the equilibrium of the contract occurs at a time when performance has been only partially rendered, hardship can be of relevance only to the parts of the performance still to be rendered.
5. A enters into a contract with B, a waste disposal company in country X, for the purpose of arranging the storage of its waste. The contract provides for a four-year term and a fixed price per ton of waste. Two years after the conclusion of the contract, the environ¬mental movement in country X gains ground and the Government of country X prescribes prices for storing waste which are ten times higher than before. B may successfully invoke hardship only with respect to the two remaining years of the life of the contract.
5. Hardship normally relevant to long-term contracts
Although this Article does not expressly exclude the possibility of hardship being invoked in respect of other kinds of contract, hardship will normally be of relevance to long-term contracts.
6. Hardship and force majeure
In view of the definitions of hardship in this Article and force majeure in Article 7.1.7, under the Principles there may be factual situations which can at the same time be considered as cases of hardship and of force majeure. If this is the case, it is for the party affected by these events to decide which remedy to pursue. If it invokes force majeure, it is with a view to its non-performance being excused. If, on the other hand, a party invokes hardship, this is in the first instance for the purpose of renegotiating the terms of the contract so as to allow the contract to be kept alive although on revised terms.
7. Hardship and contract practice
The definition of hardship in this Article is necessarily of a rather general character. International commercial contracts often contain much more precise and elaborate provisions in this regard. The parties may therefore find it appropriate to adapt the content of this Article so as to take account of the particular features of the specific transaction.
