Whatever the case was, it seemed that either the plaintiff or defendants, if not both, (and their respective counsel) were labouring under mistakes of sorts when the Consent Judgment was recorded. First, they were mistaken as to effect of s 49A of the HDB Act on the agreement reached between the parties. Section 49A provided that no owner of an HDB flat shall, within the prescribed MOP, by contract, agreement or otherwise, sell or agree to sell the flat except with the prior written consent of the HDB. Section 49A(1) had to be interpreted to include an agreement to sell that was made during the MOP, even if the sale was intended to take place after the completion of the MOP. Otherwise the words “agree to sell” in that provision would be otiose, since the word “sell” in the same provision already encompassed a sale within the MOP. Any such agreement, made without the HDB’s prior written consent, would be null and void by virtue of s 49A(3). As explained during the second reading of the Housing and Development (Amendment) Bill in 1998, when section 49A was introduced, the “amendment aims to curb speculation by providing that Sales and Purchase Agreements entered into before the seller has occupied the flat for the minimum occupation period shall be void” [emphasis added] (Singapore Parliamentary Debates, Official Report (12 October 1998) vol 69 at col 1063). In the light of this, the Consent Judgment should not have been recorded in 2013 to give effect to an agreement which was null and void under s 49A of the HDB Act.
