25 Special Condition 41 of the contract provides:
"The vendor warrants that the right of way affecting the part of the land noted on title number A769744 will be extinguished prior to completion of the matter and in the event that the vendor fails to extinguish the said easement then the purchaser shall be at liberty to rescind to the contract whereby the provision of clause 19 hereof shall apply."
26 The Defendant says that the Plaintiffs insisted on a construction of Special Condition 41 which was wrong and insisted to such a degree as to evidence an intention to accept performance of the contract only in accordance with its erroneous construction so that the Plaintiffs repudiated the contract. The Defendant says that it has validly terminated the contract because of the Plaintiffs' wrongful repudiation.
27 It is to be noted that Special Condition 39 of the contract required completion within twenty-one days after notice from the vendor's solicitor of registration of a plan of subdivision. Notice was given on 8 December 2005. The parties agree that completion was due under Special Condition 39 on 29 December 2005. Time was not made of the essence in any respect under the contract. Special Condition 29 provided that time could be made of the essence by a fourteen day notice to complete. No such notice was given by either side. The assertions of the parties about the contract and their construction of it in their solicitors' correspondence have to be viewed against this background.
28 The Defendant says that the Plaintiffs insisted upon a construction of Special Condition 41 to the effect that it entitled the Plaintiffs to compel the Defendant to remove the right-of-way referred to and to proceed to completion. The Defendants say that, on the true construction of Special Condition 41, the Plaintiffs had only two rights if the Defendant failed to remove the right-of-way before completion, namely, to rescind the contract or to affirm the contract and proceed to completion as if the contract no longer contained Special Condition 41, that is, without the benefit of the Defendant's warranty as to removal of the right-of-way.
29 Although the Defendant's construction of Special Condition 41 is arguable, I do not think it is correct. In my opinion, affirmation of the contract by the Plaintiffs would be an affirmation of the entire contract, including Special Condition 41. All that would have happened by the affirmation is that the Plaintiffs would have lost the right to rescind conferred by Special Condition 41, but they would not lose any other rights conferred by the contract including the rights conferred by the warranty contained in Special Condition 41.
30 A party to a contract may demonstrate that he or she refuses to be bound further by that contract if he or she persistently maintains an untenable construction of the contract on a matter of essential substance: see, e.g. Summers v Commonwealth (1918) 25 CLR 144, at 152; Green v Sommerville (1979) 141 CLR 594, at 611. But it is a general principle of the law of contract that the Court will not readily infer from a party's insistence on a wrong construction of a contract that he or she is unwilling to perform it according to its true construction: see Green v Sommerville at p 611, per Mason J.
31 If a party to a contract clearly demonstrates that he or she will only perform the contract in accordance with an untenable construction that conduct is called a renunciation or repudiation of the contract. The innocent party is then put to an election whether to affirm the contract and claim damages or to terminate the contract. An election to terminate must be clear and unequivocal: see Holland v Wiltshire (1954) 90 CLR 409, at 413, 416, 419, 422; and, see generally, Ryder v Frohlich [2004] NSWCA 472, at paras 102-120 per McColl JA.
32 Mr Smallbone relies on a number of letters from the Plaintiffs' solicitors as demonstrating a persistent maintenance of an untenable construction of the contract, namely, the letters of 13 December, 14 December, two letters of 22 December 2005, and 3 April 2006. In the 3 April 2006 letter, the Plaintiffs' solicitors say:
"If the transaction settles without your client complying with clause 41 and others to extinguish the right of way then our clients specifically reserve their rights against any and all parties to sue for damages with respect to such failure."
