It is firmly established by a long line of cases ... that the parties to an agreement may vary some of its terms by a subsequent agreement. They may, of course, rescind the earlier agreement altogether, and this may be done either expressly or by implication, but the determining factor must always be the intention of the parties as disclosed by the later agreement.
22 By reference to these authorities, the present facts reveal, in my view, a variation of the earlier agreements as to the method of payment to an authorised supplier. Otherwise, the arrangements between the parties concerning the ordering, processing of orders and payment of commission, remained unchanged.
23 The first respondent purported to terminate the agreements on the basis that the applicant had breached clause 4(a). There was little evidence in the present application to suggest that the purported termination was valid except for the conversation deposed to by the second respondent during which the second respondent referred to the applicant's desire to run concurrently "two distributorships" involving the first respondent and Ranbuild. Clause 8 of the agreements provided in part for the surrendering of all intellectual property and other documents relating to the Multibuild concept by the applicant to the first respondent. In addition, clause 8 required the applicant, upon termination, to immediately cease to exploit any intellectual property owned or developed by the first respondent and used by the applicant: refer clauses 8(a)(i) and (ii). These requirements were repeated in the letter of 27 February 2004. There was, however, no evidence before me to show the applicant had complied or was capable of complying with these requirements, either wholly, or partially, or if partially, to what extent. Access to the Multibuild system continued because of the way it had been set up.
24 The second respondent, in his affidavit said that notwithstanding the system's inability to prevent orders being received electronically and recorded (during a 30-day cycle) that no orders would be processed by the first respondent if a distributor's agreement had been terminated without his express instructions. An examination of the agreements admitted into evidence, however, reveals no such requirement.
25 The onus is on the respondents as the parties seeking relief on the notice of motion to satisfy the Court that the agreements were terminated prior to 3 March 2004: Sanpine v Koompahtoo Local Aboriginal Land Council [2005] NSWSC 365 (22 April 2005) at [174] [175] [176]. In Southern Foundries (1926) Limited v Shirlaw [1940] AC 701 at 729 per Lord Wright the proposition is expressed as a requirement to justify the determination of the contract.
26 What the evidence suggests is the following:
