Michelle and Tanaka are very good friends, each, worth millions of dollars. On 01 February 2019, Michellle made a signed written offer to sale part of a farm to Tanaka. They both agree that Tanaka will think about the offer. On 01 May 2019, Tanaka signed to accept the offer but did not communicate such acceptance to Michelle. Tanaka maintains she accepted the offer but Michelle is rejecting such a claim and had already sold the farm to Joseph on 2 May 2019. With reference to relevant case law, discuss whether and when in terms of our South African law, Tanaka accepted the offer. Would your answer be different if Tanaka had either posted, or faxed, or emailed, or telephoned Michelle at 4pm on 6pm on 1 May 2019?
