The Parol rule of evidence is sometimes mistakenly seen as an aid to the interpretation of contracts. There is no such thing. The Parol rule of evidence “only determines the terms of the agreement that a court considers a “contract” between the parties. It is not a rule of interpretation. Rather, it defines the purpose of the interpretation. 5 The Supreme Court (by a majority of 4:1) accepted the appeal of that decision. Lord Sumption, who gave the main verdict, stated that “I think the law should and makes a contractual provision that requires that certain formalities must be respected for variation.” He noted that the reasons for non-compliance with the non-oral clauses were “totally conceptual” and that there was “no conceptual inconsistency between a general rule authorizing informal contracting and a specific rule that gives effect to a contract requiring the letter of amendment.” Note that the conduct of the benefit cannot be technically denied, since it is conduct after the formation of the contract.21 This raises a simple but fundamental point about the merger clauses and the Parol rule of evidence: they apply only to things that occur before or at the same time as the contract.22 Even a well-developed merger clause does not exclude an amendment after creation. In general, “[d]arties to a contract” cannot, even under an explicit provision of this treaty, take the power to amend, modify or unload it by a subsequent agreement. 23 This does not mean that clauses without oral amendment are all unnecessary – some statutes make them effective, at least to some extent.24 But sometimes non-oral amendment clauses are accompanied by merger clauses, as if they were taking on the same legal concept. They are not and, to avoid confusion, merger clauses and non-oral amendment clauses should be defined in separate provisions.
Similarly, the statute of limitations for an appeal may be shorter for an oral contract than for a written contract. The most important rule for merger clauses is a rule. In the event of a dispute, non-compliance with a merger clause may open the door to the admission of all possible evidence of ancillary agreements and non-contractual undertakings that your client likely tried to omit from the contract. This could give a judicial license for ferrets by the design history of the contract (for example. B emails and TEX messages exchanged by the parties prior to the conclusion of the contract). This is something that might be difficult to explain to a client. A merger clause can act as a kind of silver ground floor that automatically transforms a partially integrated agreement into a fully integrated agreement. The inclusion of a merger clause in the contract is “likely to conclude whether the agreement is fully integrated.” 7 This means that a merger clause “[t]he additional terms” can then be excluded, even if the omission [of the written agreement] would have been obvious in the absence of such a clause. 8 As one court put it: “The purpose of a merger clause is to require the full application of the Parol rule to prohibit the introduction of extrinsious evidence, to amend, amend or contradict the terms of the letter.” 9 As a general rule, evidence of fraud is also permitted in the case of a fully integrated agreement with a fusion clause for garden varieties. However, if the contract contains an anti-reliance clause, “which states that the contracting parties did not rely on statements or assurances that are not contained in the document itself”25, it seems, most – but not all – of the courts that have ruled on the issue assert that claims of fraud are excluded from the inducement.26 You should not characterize the letter as merely an indication of the total or final agreement of the parties.11 You should not use the language used by the courts.
