61 However, an examination of the defences reveals that, although the first defendant concedes in its defence that a contract of insurance existed, it maintains that the Policy insured Petch and his partner Harding pursuant to the terms of the Law Institute Insurance Package against certain perils for the period from 19 May 1986 to 19 May 1987. All other allegations made by the plaintiffs as to the contract of insurance, including the allegation that there was a variation of the contract in or about August 1986 to include cover for Imaging, are denied. This denial is critical because, as revealed in the particulars to paragraph 8 of the amended statement of claim, in or about August of 1986 Mr Evans, in conversations he is alleged to have engaged in with Petch and Fahnle of Imaging, is said to have agreed that Imaging was to be covered under the Policy. The amended statement of claim, in reliance on these particulars in paragraph 8, then alleges in paragraph 9 that, with effect from about August 1986 or thereabouts, a variation of the contract of insurance was implemented pursuant to which Imaging was insured under the Policy. Sun Alliance denies this allegation in its defence.
