Integration is a notion of art in contract law. As opposed to a non-integrated or partially integrated agreement, a fully integrated agreement replaces all previous agreements, oral or written, between the parties and, in most cases, a fully integrated agreement cannot be supplemented by additional terms. The question of whether entire contractual clauses allow the parties to exclude claims based on misrepresentation and/or implied conditions has been the subject of much dispute. However, a recent court of appeal, AXA Sun Life vs. Campbell Martin, provided useful guidance for formulating such clauses to ensure that no implied terms or pre-contractual negotiations are construed as part of the contract. AXA has appointed representatives to sell products under general retainer agreements containing a number of standard clauses. When the agreements were terminated, the question arose as to whether the entire contractual clause in any termination agreement was effective to exclude claims based on allegations: the (second) reformulation of contracts reminds us, however, that an agreement or any form of writing “cannot prove its own existence”. A whole agreement clause is relevant evidence and strong evidence that the courts must consider, but it is not conclusive. The courts only have to determine whether an agreement is complete and incorporated in the event of ambiguity as to the agreement or certain conditions, or in the event of disagreement or dispute between the parties. .
