Murden v NM Superannuation Pty Ltd as trustee of the AMP Super Fund

In the case of Murden v NM Superannuation Pty Ltd as trustee of the AMP Super Fund, the applicant sought leave to amend his statement of claim to include a defence of "change of position" in relation to a payment received. The application was made shortly before the matter was set for a five-day hearing in February 2025, and the proposed amendments were deemed critical to the applicant’s case. The primary legal issue before the court was whether the applicant should be granted leave to amend his pleadings at such a late stage in the proceedings. The court was also required to consider the potential impact of such an amendment on the trial, other litigants, and the efficient use of court resources.

The court denied the application, highlighting several key factors. Firstly, the proposed amendment sought to introduce a new defence that required substantial new evidence and potentially new witnesses, which would necessitate adjourning the five-day trial. Secondly, the applicant had ample time to identify and plead the necessary claims but failed to do so without explanation. The court found this unexplained delay, especially after being warned of the need for amendments, to be a significant factor against granting leave to amend. The court balanced the applicant's need to present his best case against the broader considerations of fairness to the respondents, the impact on other litigants, and the efficient use of court resources. Ultimately, the court concluded that the applicant had had sufficient opportunity to plead his case correctly and that the absence of any explanation for the delay weighed heavily against granting leave to amend.

The court's decision was grounded in the principles of fairness and efficient case management. It acknowledged the importance of allowing parties to present their best case but also emphasised the need to maintain a fair and orderly process. The court's refusal to grant leave to amend was a reflection of the need to balance the applicant's rights with the broader interests of justice and the efficient administration of the court system. The final orders included dismissing the application, requiring the applicant to pay the respondents' costs, and extending certain deadlines related to the filing of a Court Book and other procedural matters.
