National Australia Bank v McFarlane

National Australia Bank sued McFarlane for malicious prosecution and collateral abuse of process, with the case being heard in the Federal Court of Australia. The dispute arose from the bank's actions in pursuing legal proceedings against McFarlane for breach of contract, which were subsequently dismissed. McFarlane argued that the bank's actions constituted malicious prosecution and collateral abuse of process. The court was tasked with determining whether the elements of each tort were satisfied and whether McFarlane was entitled to injunctive relief.

The court first examined the elements of malicious prosecution, which include the initiation of proceedings, absence of probable cause, malice, and the termination of proceedings in the plaintiff's favour. The bank argued that it had probable cause to initiate proceedings against McFarlane, as there was evidence to support a claim for breach of contract. However, the court found that the bank's actions were not reasonable or prudent, and that it had acted with malice. The court also found that the proceedings were terminated in McFarlane's favour, as the court dismissed the bank's claim. The court then examined the elements of collateral abuse of process, which include the existence of a primary proceeding, an act done in the course of that proceeding, and that act being done with malice and without probable cause. The court found that the bank's actions in pursuing legal proceedings against McFarlane constituted an act done in the course of a primary proceeding, and that it was done with malice and without probable cause.

The court found in favour of McFarlane, awarding damages for both malicious prosecution and collateral abuse of process. The court also granted McFarlane injunctive relief, preventing the bank from pursuing further legal proceedings against him without first obtaining the court's approval. The court emphasised the importance of conducting legal proceedings with due care and attention, and the potential consequences of acting without probable cause or with malice. The final orders included the payment of damages by the bank to McFarlane and the granting of injunctive relief to McFarlane.
