National Australia Bank Limited v Sayed (No 4)

The case of National Australia Bank Limited v Sayed (No 4) involved a dispute between the bank, as the plaintiff, and Sayed, the defendant, concerning the enforceability of an in principle agreement reached between the parties. The case was heard in the Supreme Court of Victoria. The bank sought specific performance of the in principle agreement, which the Court of Appeal had previously determined was not binding. The central legal issues the court had to address were whether the in principle agreement was binding, whether the bank had repudiated or abandoned the agreement, whether there was laches or unconscionable delay on the part of the bank, and whether the principles of res judicata and issue estoppel applied.

The court analysed the nature of the in principle agreement and determined that it was not binding due to the absence of a formal deed of settlement and release. The court examined the conduct of the bank to ascertain whether it had repudiated or abandoned the agreement. The court concluded that the bank had not repudiated the agreement but had instead elected not to rely on it. The court also considered whether the bank's delay was unconscionable or amounted to laches, finding that there was no such delay. Furthermore, the court explored the applicability of res judicata and issue estoppel, concluding that there was no abuse of process amounting to issue estoppel, and that the bank had not elected to rely on the in principle agreement.

The court found that the in principle agreement was not binding and that there was no laches or unconscionable delay on the part of the bank. The principles of res judicata and issue estoppel did not apply, and there was no abuse of process amounting to issue estoppel. The bank's additional conduct did not give rise to an estoppel. The court dismissed the bank's claim for specific performance.
