The first appellant (M.B. Ziko (Pvt) Ltd) purchased a property known as Amsterdam Portion of Odar in 1996 with a loan from Founders Building Society. On 7 May 1998, the first appellant sold the same property to the first respondent (Cestaron Investments) for $7,000,000. Under the sale agreement, the purchase price was payable in instalments: $1,051,181 upon signing (to be forwarded to Founders Building Society to obtain the title deed), $2,500,000 after obtaining the original title deed, and the balance in six monthly instalments. The second appellant (Manase & Manase Legal Practitioners) acted as the first respondent's agent to obtain the title deed and later as selling agent for the second respondent (Kilberry Investments), which had been ceded development rights by the first respondent. The second appellant obtained the original title deed and wrote to the first respondent on 15 July 1998 confirming possession and absence of encumbrances. The first respondent paid $1 million of the $2,500,000 due under clause 2(b). After demands for the outstanding $1,500,000 went unpaid, the first appellant cancelled the agreement on 30 September 1998. The respondents then sought court intervention, claiming the cancellation was unlawful because they had not obtained the original title deed as required by clause 2(b).
