General principles of insurance
1.1 Contract formation
1.1.1 General rules
The rules of law governing contracts of cargo insurance are those that govern the formation of most other commercial contracts. Accounting for about 30 per cent of world trade in terms of value, âcargo carried by air forms only one element in the complex logistical chain that accompanies the sale and shipment of goods generallyâ.1 That is true, firstly, of contract formation,2 which occurs when the offer of one party, typically the applicant for insurance, is accepted by the other party, the insurer. Commonly, however, the applicant obtains a prior quotation from the insurer which, in the language of contract law, is not an offer but an âinvitation to treatâ. If then the applicant âacceptsâ the quotation by completing the insurerâs application form on that basis, the form is the offer to be accepted (or not) by the insurer.
If indeed the insurer is not willing to accept that offer, that may be the end of the matter. Alternatively the insurer may respond with a counteroffer,3 which may then be accepted by the applicant. However, sometimes the applicant may meet the counteroffer with a further offer for acceptance (or rejection) by the insurer, and this process continues until the offer of one or other is accepted or rejected (the end of the matter).
This process, in the format of offer and acceptance, although common and useful,4 is not essential or exclusive for testing whether a contract has been agreed.5 Sometimes a contract, in particular a non-standard contract, is the product of negotiations. However, the traditional offer and acceptance analysis remains the safest approach unless there is clear evidence that a different outcome was intended.6
1.1.2 Terms
In any case, for an enforceable contract the terms must indicate:
- (i) the identity of the parties;
- (ii) the type of cover intended;
- (iii) the limits of the cover;
- (iv) the period of the cover;
- (v) the events covered;7
- (vi) particularly for air cargo insurance, the limits â whether the aggregate limit or the limit per claim.
Other terms, although important and essential to the business efficacy of the insurance, may be implied.8
1.1.3 Particular forms
On to this skeleton of essential terms parties may well construct a more detailed statement of their intention. Sometimes they negotiate a construct that is entirely specific to the case, but often parties draw on appropriate standard market terms. In particular, in cases of air cargo insurance they may turn to the work of the Aviation Insurance Clauses Group (AICG) for non-binding standard wordings, clauses and variants for use in aviation insurance policies.9
The AICG arose in 2005 when the European Commission announced that:
Following an investigation by the Commission, leading European aviation insurers have undertaken to reform their practices as regards the operation of aviation insurance in order to promote more competition and transparency. The reforms foresee inter alia greater transparency in key industry committees based in London, including one that establishes standard wordings for aviation insurance policies and clauses.
As a result, the AICG was established later in 2005 by the Lloydâs Market Association and the International Underwriting Association of London.
Contracts with AICG clauses are concluded in London at Lloydâs, where some degree of negotiation usually precedes final agreement, and which has particular features.10 Today, it is possible to conclude contracts electronically by placing risks in the market by data interchange using ACORD standards.11 Such innovations, however, do not alter the basic legal analysis of the conduct of business at Lloydâs.
1.1.4 Applications
Many contracts of insurance are concluded simply by the insurerâs acceptance of an application for insurance submitted by the person seeking insurance, on a form drafted and made available to applicants by the insurer. Where this is the case, the statements made in the form, statements about the applicantâs circumstances and thus about the risk to be insured, are important. They are usually representations of fact, which, if untrue, entitle the insurer to rescind the resulting contract of insurance. Further, if there is a statement that the form describes as a âbasis clauseâ, what the applicant states in the application might become a term of the contract itself; and again if untrue or unfulfilled, entitle the insurer to refuse a claim.12
Unless the parties know what they are committing themselves to, the courts are slow to infer intention to contract and hence slow to infer that an alleged offer is indeed an offer in law, unless the offer (and hence the contract) is certain in content. Uncertainty arises in two ways: in what the parties have said â ambiguity (below, (a)), and in what the parties have not said â incompleteness (below, (b)). However, gaps can sometimes be filled with implied terms or settled indirectly (below (c)).
1.1.4 (a) Ambiguity
Courts cannot give effect to intention that is unclear; and they will not guess what the parties might (or should) have intended;13 however some courts take the more flexible view that it is sufficient that the reasonable businessman would have understood the main terms of the transaction.14 In any event, courts will not rewrite contracts.15
1.1.4 (b) Incompleteness and implied terms
In principle, an incomplete application cannot be an offer, if what is missing is an essential term,16 of the kind listed above (1.1.2) such as the amount of insurance.17However, some terms essential to the business efficacy of the insurance, such as the duration of cover, are likely to be implied. Other terms, such as the geographical limits of cover, may or may not be implied according to the case. That is true of war risks.18 Premium rates will be implied where the particular risk is a standard risk for which there is an ascertainable market rate,19 as will terms about the mode of payment.20
Implied terms are sometimes categorised according to their source. For instance (a) they may be implied from previous dealings between the particular parties;21 or (b) they may be implied from the custom of the insurance industry, provided that they are certain (ascertainable),22 well established in the industry and contrary neither to law nor to the express terms of the contract.23 Finally (c) it is assumed that people know that insurers have standard terms,24 so that the application of the person seeking insurance is presumed to be on the basis of the insurerâs standard terms (if any) for the kind of risk proposed,25 provided that sufficient awareness of the terms can also be presumed.26 However, the law requires extra and special notice of unusual and onerous terms, especially restrictions on cover, if they are to be part of the contract.27
1.1.4 (c) Terms settled indirectly
Courts give effect to terms that have not been settled by the parties themselves and stated in the contract but incorporated in the contract by reference,28 such as the AICG clauses mentioned above. The reference may be not only to the market but to a nominated person to settle the matter.29
In this connection, the practice in the London subscription market should be noted, whereby on the basis of a leading underwriter agreement, a risk is first and mainly assessed by a leading underwriter,30 and other subscribers to the risk (followers) authorise the leader to settle outstanding issues (including terms) concerning the risk.
1.1.5 Finality
If it is to be accepted and become the basis of an enforceable agreement, any offer to contract must indicate a real willingness to be bound on the part of the offeror: a matter of construction of the offer, bearing in mind the context in which it is made. There is a presumption that a document, such as an insurance application, which looks like a firm contract offer is indeed intended as such, which is rebuttable, however, where there is reason to infer otherwise. For example, the circumstances in which the application is made may be such that it is contrary to commercial...
