Please use relevant case law in NSW Australia to assist. John and Kelly discussed on phone about the purchase of John's property situate at 73 Lynn Street, Victoria. John, anxious to finalise the deal sends a DocuSign agreement for the sale of land to Kelly for her consideration and consent. Kelly is unwilling to use a DocuSign (electronic document) land agreement and asserts that DocuSign fails to meet the formalities requirements for a valid contract.

i. Advise John and Kelly on the veracity of Kelly's assertion.

ii. Assuming the land transaction between John and Kelly was finalised solely on the basis of the telephone discussion, what would be the consequences if Kelly decided not to follow through with the oral agreement.
