Contractual limitations on damages are of critical importance, allowing parties to better assess and control business risks arising from a commercial transaction. It is thus no surprise that some form of damage limitation is found in many commercial contracts today. Yet, despite their prevalence, contractual limitations on damages give rise to difficult questions that go to the heart of the legal system, such as how to balance the parties’ freedom to contract against provisions of mandatory law, and the weight to be given to the respective interests of creditors and debtors.
Contractual limitations on damages are agreements whereby the parties limit or exclude the availability of damages that would otherwise be available under statutory law. They differ from more general ‘exemption clauses’ or ‘liability limitations’ (Haftungsbegrenzungen) – clauses that absolve a party, whether in whole or in part, from liability under a contract or for a related tort, or that qualify that liability – in that they relate specifically, and exclusively, to damages. Clauses that go beyond a limitation of damages, for example, because they exclude the coming into being of a contractual duty in the first place, are not the subject of this chapter.
After first considering some general aspects relating to contractual limitations on damages (see ‘General Aspects of Contractual Limitations on Damages’, infra) we will address the different forms that such limitations generally take (see ‘Forms of Contractual Limitations on Damages’, infra). While the scope of the chapter does not allow for an in-depth analysis of how contractual limitations on damages are dealt with under different legal systems, key differences in the approaches to such limitations will nevertheless be highlighted and should be understood as red flags to keep in mind when confronted with such provisions in practice.
General aspects of contractual limitations on damages
Agreements on contractual limitations on damages and their incorporation
A contractual limitation on damages needs to be agreed upon by the contracting parties. It thus requires a contractual relationship between the creditor and the debtor.
As long as there is consensus on the content, provisions containing contractual limitations on damages can normally be included in a contract without further ado.
In general, contract terms can also be implied, and be incorporated through the conduct of the parties. However, reading a limitation of damages into a contract on the basis of party conduct will rarely be done in practice, and requires a previous course of dealings between the parties on the same terms. In particular, mere personal relationships or the existence of goodwill will generally not suffice to assume a limitation of liability.
Limitations on damages are frequently contained in general terms and conditions (GTCs). GTCs are contract terms that are pre-formulated by one party for a large number of contracts. They are only effectively included in an agreement where the contract itself refers to them. In civil law systems, the contracting party needs to have the possibility to take note of the GTCs that were pre-formulated by the other party, whereas in other systems it suffices for the written agreement referring to the GTCs to be signed for them to be binding. In civil law systems, any GTC provisions that are considered so unusual that they could not reasonably have been expected will not be considered to be a valid part of the agreement and are thus invalid. On the other hand, common law systems frequently require a showing of fraud or misrepresentation for a party to be able to escape the consequences of its signature. Similarly, where a party claims to have misunderstood the GTCs, it will have to satisfy the court that the document is radically different from that which the party intended to sign and that the mistake was not due to carelessness. Some civil law countries, and in particular German law, govern in detail the limitations of liability allowed in standard terms (see ‘Limits of contractual limitations on damages’, infra).
Interpretation/construction of contractual limitation on damages
Contractual limitations on damages are interpreted in the same manner as other contractual provisions, with the aim being to determine the parties’ actual intent. There exist a number of methods that aim at arriving at the contractual intent.
The starting point is usually the wording used by the parties, but the purpose of the agreement and the organisation of the various provisions of an agreement are also considered and may prevail over a strict interpretation of the wording. For example, an exemption clause may be so broad and general in scope that to apply it literally would create an absurdity or defeat the main purpose of the contract into which the parties have entered. The courts will then need to ascertain the meaning to give effect to the agreement of the parties.
In the Anglo-Saxon tradition, the contra proferentem rule and the rule that exclusion clauses need to be interpreted strictly are also frequently applied. In Internet Broadcasting Corp Ltd and (t/a NETTV) v. MAR/LLC, the High Court held that there is a presumption, which appears to be a strong presumption, against exemption clauses being construed so as to cover deliberate, repudiatory breaches. Similarly, in Bovis Construction (Scotland) Ltd v. Whatlings Construction Ltd, the House of Lords ruled that a clause that limited liability should state ‘clearly and unambiguously the scope of the limitation and would be construed ‘with a degree of strictness’, albeit not to the same extent as an exclusion or indemnity clause’.
Special consideration is required where an agreement provides for both a warranty and limitation of liability. In such a case, interpretation of the agreement may lead to the conclusion that one of the clauses prevails, for example, where the warranty is contained in the main text of the agreement and the limitation of liability in the annexed standard terms. On the other hand, where a party gives a warranty without at the same time also assuming liability for a breach of the warranty, the warranty may be considered to be consistent with the limitation of liability.
Burden of proof
It is for the party seeking to rely on the exemption clause to show that the clause, on its true construction, covers the obligation or liability that it purports to restrict or exclude.
Limits of contractual limitations on damages
Party autonomy and contractual freedom are not unlimited. Limitations of liability and of damages are a well suited example to illustrate the boundaries placed on contractual freedom by mandatory law. Statutory limitations to contractual agreements limiting the availability of damages are common in virtually all countries.
In Germany, parties cannot agree in advance to exclude liability for unlawful intent. If contained in standard terms, an agreement to exclude liability for negligence will be considered invalid in the event of a violation of essential duties. Swiss law is more rigid, as it provides that any agreement purporting to exclude or limit liability for unlawful intent or gross negligence in advance is void. The court also has discretion to invalidate an advance exclusion of liability for minor negligence in certain cases. Even narrower restrictions exist for consumer contracts and GTCs.
In New York, the courts have a policy against limiting liability in contracts in cases of grossly negligent conduct as well as purely intentional wrongdoing.
In England, the Unfair Contract Terms Act 1977 (UCTA) restricts the operation and legality of some contract terms. The UCTA contains a number of restrictions to limitations of liability; these restrictions mainly concern the liability for death or personal injury resulting from negligence. In addition, the UCTA applies a reasonableness test, requiring that any term ‘shall have been a fair and reasonable one to be included having regard to the circumstances which were, or ought reasonably to have been, known to or in the contemplation of the parties when the contract was made’.
Contractual limitations on damages that exceed the statutory limits are not effective. Depending on the applicable law and the type of contractual limitation involved, the limitation on damages may be rendered absolutely ineffective or it may be partially effective, in particular, only insofar as the term does not exceed the limits of mandatory law or satisfies the requirement of reasonableness in the common law system.
Consequences of contractual limitation on damages
Contractual limitations on damages that are validly agreed upon and that do not go beyond the limits described above are valid and serve to limit the availability of damages. In particular, a claim for damages does not exist to the extent it has been effectively excluded. On the other hand, a primary duty to perform will not be affected by contractual limitations on damages.
Forms of contractual limitations on damages
Liquidated damages/penalty clauses
Common law jurisdictions distinguish clearly between liquidated damages and penalties. Liquidated damages are an amount contractually stipulated as a reasonable estimation of the actual damages to be recovered by one party if the other party breaches the agreement. Traditionally, courts have upheld liquidated damages clauses.
On the other hand, penalty clauses are contractual provisions that assess against a defaulting party an excessive monetary charge unrelated to actual harm. Penalty clauses are generally considered unenforceable. In the words of Atiyah:
It not infrequently happens that contracts provide for what is to happen in the event of a breach by the parties, or by one of them. Such provisions may be perfectly simple attempts to avoid future disputes, and to quantify the probable amount of any loss. That is unobjectionable. But sometimes clauses of this kind are not designed to quantify the amount of the probable loss, but are designed to terrorize, or frighten, the party into performance. For example, a contract may provide that the promisor is to pay £5 on a certain event, but if he fails to do so, he must then pay £500. Now a clause of that kind is called a penalty clause by lawyers, and for several hundred years it has been the law that such promises cannot be enforced. The standard justification for the law here is that it is unfair and unconscionable to enforce clauses which are designed to act in terrorem.
Although the parties’ choice of ‘penalty’ or ‘liquidated damages’ in their contract will serve as prima facie evidence of the term actually stipulated, the expression used by the parties will not be conclusive. Rather, the court will have to determine whether the payment stipulated in fact constitutes a penalty or liquidated damages. To assist this task of construction, various tests have been suggested. For example, a payment obligation will be considered to constitute a penalty where the sum stipulated is extravagant and unconscionable when compared with the greatest loss that could conceivably have followed from the breach.
There is no such general exclusion of penalty clauses in civil law countries. Quite to the contrary, in Switzerland as well as in Germany and Austria, a penalty can be promised for non-performance or defective performance of a contract, and unless otherwise agreed, the creditor may then compel performance or claim the penalty. In fact, the Swiss Federal Supreme Court has even confirmed that a contractual penalty may be agreed for the purpose of punishing one of the parties. The penalty is payable even if the creditor has not suffered any loss or damage. The parties are free to determine the amount of the contractual penalty. However, under Swiss, German and Austrian law, the court may reduce penalties that it considers excessive in its discretion.
Liquidated damages and penalty clauses are thus treated differently in various legal systems. This circumstance should be carefully considered when drafting an agreement, but also later on if any such clause is in dispute.
Stipulation of a maximum amount of damages/limitation clauses
Clauses limiting the amount of damages, also called limitation clauses, are generally admissible in common law. Pursuant to Ailsa Craig Fishing Co Ltd v. Malvem Fishing Co Ltd:
Clauses of limitation are not regarded by the courts with the same hostility as clauses of exclusion: this is because they must be related to other contractual terms, in particular to the risks to which the defending party may be exposed, the remuneration which he receives, and possibly also the opportunity of the other party to insure.
There is even case law holding that the principle of strict construction is not applicable when considering the effect of clauses merely limiting damages. The modern view, however, seems to be that the general approach to interpretation, which is to ascertain the objective intention of the parties, also applies to limitation clauses. Under English law, a clause providing for a maximum amount of damages will be valid if the limitation is considered to be reasonable. With regard to contract terms that restrict damages to a specified sum of money, the UCTA provides that regard shall be had in particular to (a) the resources that the person seeking to restrict damages could expect to be available to him or her for the purpose of meeting the liability should it arise; and (b) how far it was open to him or her to cover himself by insurance. The contract value and the turnover of the party seeking to restrict damages are also taken into consideration.
In civil law systems, caps on damages are generally valid, albeit only to the extent the cap does not violate the statutory limits to limitations of damages. Moreover, in some civil law jurisdictions, such restrictions will be examined to ensure that they do not unduly restrict damages in such a manner as to exclude coverage of the actual damages incurred.
Clauses stipulating a maximum amount of damages are thus generally admissible, although they may nevertheless be subject to substantial restrictions, particularly in certain civil law systems.
Exclusion of a particular damage type
Contractual limitations of damages may also limit the availability of certain types of damages.
Damages arising from death or personal injury can hardly ever be excluded. For example, under English law, the UCTA provides that ‘[a] person cannot by reference to any contract term or to a notice given to persons generally or to particular persons exclude or restrict his liability for death or personal injury resulting from negligence’. Similarly, under Swiss law, clauses excluding liability for personal injury are ineffective. If liability for personal injury cannot be exluded, damages for personal injury cannot – following the argument a maiore ad minus – be excluded either. It may thus be preferable to make a reservation for damages arising out of personal injury when drafting clauses limiting the availability of damages.
On the other hand, loss or damage that does not result directly or naturally from the breach of contract can generally be excluded, unless the limitation exceeds the mandatory limits. These damages are referred to as consequential damages or indirect damages.
Under English law, case law provides guidance with regard to what is considered a consequential loss or damage and to what extent a clause excluding consequential loss or damage is effective. For example, in British Sugar Plc v. NEI Power Projects Ltd the relevant clauses provided that ‘[t]he seller will be liable for any loss damage cost or expense incurred by the purchaser arising from the supply of any such faulty goods or material or any goods or materials not being suitable for the purpose for which they are required save that the seller’s liability for consequential loss is limited to the value of the contract’. The value of the contract was £106,000, while the damages claimed for the breach were £5 million. The Court of Appeal stated that the clause simply limited the liability for loss and damage not directly arising from the breach to an amount equal to the value of the contract. Similarly, in Deepak Fertilisers & Petrochemical Group v. Davy McKee (London) Ltd the clause explicitly excluded ‘indirect or consequential damages’ and ‘loss of profits’. The court considered the lost profits as damages that flow directly from the breach. However, since the clause expressly excluded lost profits, these could not be recovered. English courts also frequently give consideration to Hadley v. Baxendale to determine which damages directly follow from a breach.
In civil law countries, the terminology is less clear. In Switzerland, the distinction between direct and indirect damages is made on the basis of the length of the causal chain involved. On the other hand, under German law, indirect damages are damages affecting an asset other than the object of the contract that was breached. The boundaries placed on limitations on damages by statutory law also apply to any types of damages that are excluded. For example, under Swiss law, the governing principle is that damages for gross negligence cannot be excluded. Accordingly, even if the contract excludes consequential damages, any consequential damages arising from gross negligence will still be owed. Similarly, exclusions of indirect damages under German law will be invalid to the extent that they are contained in GTCs and seek to exclude any damages arising out of a violation of essential duties.
In sum, it seems that exclusions of a particular type of damage are not an effective means of managing risk contracts subject to civil law, as these systems tend to prescribe a mandatory liability for damages arising from gross negligence or wilful misconduct. To the extent that the damages arise from simple negligence or without fault, these may be excluded as a whole, without there being a need to limit the exclusion to consequential damages. On the other hand, common law systems tend to accept exclusions of different types of damages, as long as such exclusions are reasonable, and in fact, it may be precisely the exclusion of consequential damages but not direct damages that may render an exemption clause reasonable.
Modifications with regard to other aspects
Further clauses may also have the effect of limiting damages. For example, the parties may agree to shorten the time limit for the notification of a breach of contract or shorten the statutory limitation periods to the extent permissible under the applicable law. The parties may also modify the statutory burden of proof or the standard of proof. For example, under Swiss law, an obligor who fails to discharge an obligation must make amends for the resulting loss or damage unless he or she can prove that he or she was not at fault. The parties can amend this principle by agreeing that the injured party needs to prove that the obligor was at fault, which may – as the case may be – have the effect of a limitation on damages.
These examples show that the position of the creditor may be affected by clauses modifying the modalities of liability. Such clauses, if admissible under the applicable law, may have the same effect as contractual limitations of damages in the strict sense.
Limitation of damages owed by third parties
A different issue is whether contractual limitations can operate to protect a person who is not a party to the contract.
Common law tradition generally considers that the principle of privity of contract prevents a contractual agreement from granting benefits to third parties or imposing burdens upon them. Based on this principle, courts have traditionally considered that third parties cannot claim the benefit of an exemption clause between two contracting parties since they are not a party to said contract. These decisions have been considered to be too rigid, in particular, between businessmen. In Scruttons Ltd v. Midland Silicones Ltd, the argument was made that the contracting party, in addition to contracting on his or her own behalf, is also contracting as an agent for the third party to whom the provisions should apply. The situation has become clearer with the enactment of the Contracts (Rights of Third Parties) Act 1999. Section 1(6) of said act provides that ‘[w]here a term of a contract excludes or limits liability in relation to any matter references in this Act to the third party enforcing the term shall be construed as references to his availing himself of the exclusion or limitation.’
In civil law systems, the parties to an agreement are generally allowed to limit their liability for any loss or damage caused by an associate to whom the performance of an obligation or the exercise of a right arising from a contractual obligation is delegated. However, the majority view is that such clauses do not exclude the liability of the associate himself (based on tort, etc.).
In sum, it seems that clauses limiting damages owed by third parties tend to be more effective under common law.
The above explanations demonstrate that the general concepts regarding how contractual limitations of damages can be agreed, how they are interpreted, who bears the burden of proving such limitations, and the consequences of such limitations are similar even in diverse legal traditions.
On the other hand, the enforceability of contractual limitations on damages varies quite heavily between the common law and the civil law traditions. While the common law system tends to apply a reasonableness test, civil law countries generally focus on the degree of fault and consider agreements purporting to exclude liability for unlawful intent and gross negligence in advance to be ineffective. This difference is crucial for the availability of several forms of contractual limitations on damages.
Differences in the approach towards contractual limitations on damages emerge in almost all forms of such limitations on damages that have been assessed above.
Liquidated damages and penalty clauses are generally permissible in civil law systems, with the caveat that excessive penalties may be reduced by courts. On the other hand, penalty clauses, to the extent they provide for a monetary charge unrelated to the actual harm, are considered ineffective in the common law tradition.
Stipulations of a maximum amount of damages are effective in the common law tradition if the limitation is reasonable. In civil law systems, caps on damages are only admissible if they do not restrict the damages to an extent that is not admissible under statutory law; in other words, in case of wilful intent or gross negligence, a cap may not be effective.
Clauses that exclude a particular type of damages generally face the same differences in approach. One exception to this rule are damages arising from death or personal injury, which can hardly ever by excluded. On the other hand, the common law tradition generally considers the exclusion of consequential damages to be valid, as long such exclusions are reasonable. But in civil law, exclusions of a particular type of damage do not seem to be very effective, since such limitations may not overcome the mandatory liability for damages arising from gross negligence and wilful misconduct.
A further possibility that should be taken into consideration are clauses that modify the liability with regard to other aspects, such as the statutory limitation periods, which may have the same effect as contractual limitations on damages.
With regard to limitation of damages owed to third parties, it seems that the common law tradition allows third parties to avail themselves of the contractual limitation of liability, while this does not seem to be the case in civil law systems.
In sum, no general statement can be made about which law system is more favourable towards contractual limitations on damages. Rather, the individual contractual limitation sought or in dispute must be assessed under the applicable law. And depending on the importance of contractual limitation on damages, the law applicable should be chosen with a view to maximising the enforceability of such limitations.
