Per the Court:
(1) It is a fundamental principle of land law that a party who seeks to terminate a contract for breach of an essential stipulation, must itself be ready, willing and able to complete. [33]-[35]
McNally v Waitzer [1981] 1 NSWLR 294 at 296; Malouf v Sterling Estates Development Corporation Pty Ltd [2002] NSWSC 920 at [36]; Sterling Estates Development Corporation Pty Ltd v Malouf [2003] NSWCA 278; 58 NSWLR 685; Carrapetta v Rado [2012] NSWCA 202; 16 BPR 30, 997 at [25]; Kraguljac v A & B Property Developments Pty Ltd (No 2) [2012] SASC 1 at [92].
(2) The Vendor had a contractual obligation to provide to the Purchaser on settlement documents of title, including an executed transfer in registrable form. Where, as here, a purchaser has the contractual obligation to serve the transfer on the vendor but the transfer served was not in an appropriate form for execution by the vendor, the vendor is not entitled merely to execute the transfer in the form in which it is served where doing so would prevent it being a registrable instrument. [51]
(3) A vendor who fails to provide to the purchaser at settlement a transfer in registrable form, will not be ready willing and able to complete the contract. [36]-[46]
(4) Where a notice to complete has been served, the time for completion, thus made essential, will be binding on both parties. [39]
Halfpenny v Wilson (1967) 87 WN (1) (NSW) 547; Falconer v Wilson [1973] 2 NSWLR 131 at 145.
(5) A vendor not ready willing and able to complete, is not entitled to terminate for the purchaser's purported failure to complete. [48], [59]
(6) A purchaser will not be entitled to terminate where its own non-essential breach contributed to the vendor's breach of an otherwise essential term. However, the application of the "prevention principle" does not convert a purchaser's non-essential breach into an essential breach. [58]
Trollope & Colls v North West Metropolitan Regional Hospital Board [1973] 1 WLR 601 at 607; Champion Homes Sales Pty Limited v DCT Projects Pty Limited [2015] NSWSC 616 at [156].
(7) The equitable doctrine expounded in Tanwar Enterprises Pty Ltd v Cauchi [2003] HCA 57; 217 CLR 315 is appropriately conceptualised as relief against unconscientious reliance by a vendor on their right of termination, as opposed to relief against forfeiture of the purchaser's equitable interest.
