Australian Securities and Investments Commission v Macdonald (No 4)

In the matter of Australian Securities and Investments Commission versus Macdonald, the Federal Court addressed the admissibility and relevance of documents provided late in the proceedings. The Australian Securities and Investments Commission sought to establish the chain of custody and relevance of certain documents obtained from the 11th defendant's substantial shareholder and its representatives. The court needed to determine whether leave should be granted for the filing of an affidavit that corrected earlier errors and outlined the document's path to the plaintiff, as well as whether the late submission should be allowed under the circumstances, given that the documents were not included in a previously ordered tender bundle.

The legal issues before the court involved the principles of admissibility and relevance in the context of late-filed affidavits and documents. The court had to consider whether the late application to file the affidavit was justified, and if the documents were relevant to the case. Additionally, the court examined whether the refusal of leave would be unfair and whether allowing the cross-examination of the defendant's evidence in reply would be unjust. The court was tasked with balancing the principles of procedural fairness against the potential prejudice to the opposing party.

The court found that the late filing of the affidavit and the accompanying documents could be justified on the basis of the justice of the case. It was determined that the documents were relevant and necessary to establish the chain of custody and the path of the documents to the plaintiff. The court held that the late filing did not prejudice the opposing party to the extent that it would be unjust to refuse the leave. Furthermore, the court concluded that allowing cross-examination in reply would not be unfair and was necessary for a fair determination of the case. Consequently, the court granted leave for the affidavit to be filed and for the cross-examination to proceed.

The final orders of the court allowed the late filing of the affidavit and the related documents, and permitted the cross-examination of the defendant's evidence in reply. The court's decision recognised the importance of ensuring that all relevant evidence is considered, while also maintaining procedural fairness and avoiding undue prejudice to the parties involved.
