ISSUES: 1. Is Beehun binded to Kuey Teow? 2. Can Beehun sell his house to his aunty? SOLUTION: 1. According to general principal S4 (1), communication of acceptance is effective only when it is communicated. According to the case of ENTORES LTD V MILES FAR EAST CORPORATION, the court ruled that when a contract is made by post, acceptance is only complete when the offeree has put the letter into the mail box. Therefore, the offeror is not binded to the offeree until the accpetance is made. We can conclude that the postal rule applies to email from the case of Chwee Kin Keong V Digilandmall.com Pte Ltd whereby the court ruled that unlike fax or a telephone call, email is not instantaneous. Emails are processed through servers, routers and internet service providers. Similarly to the case above, Beehun is not binded to Kuey Teow until Kuey Teow accepts the offer and sends the acceptance to Beehun. Acceptance by email, similar to acceptance by post only makes Beehun binded to Kuey Teow once he sends the email. Therefore, Beehun is not binded to Kuey Teow when he sold the house to his Aunty. According to Section 4(2) (a), communication of acceptance is complete when it is transmitted to the offeree and according to section 4(2) (b), acceptance is complete when offeror knows it. This can be seen in the case of Byrne V Vantienhoven, the judge made a verdict that when an offer is made and accepted through post, contract was completely concluded once the letter of acceptance had been posted, even though the letter did not reach its destination. Application: However, due to the fact that Kuey Teow only sent his email after the house was sold, Beehun is not binded to Kuey Teow because the offer was accepted by a different party, in this case, his aunty. 2. If Kuey Teow had sent the email on the day instructed, Beehun would be binded to him and not be able to sell the house to his aunty. Based on the case of Byrne V Vantienhoven, the judge ruled that when an offer is made and accepted through post, contract was completely concluded once the letter of acceptance had been posted, even though the letter did not reach its destination. We can apply this same verdict when using e mail, where if Kuey Teow had emailed Beehun before he sold the house to his aunty, Kuey Teow has sufficient elements to sue Beehun for breaching the contract. Thefore, Beehun can sell his house to his aunty, and Kuey Teow cannot do anything about it.
