Sino Iron Pty Ltd v Mineralogy Pty Ltd

The case of Sino Iron Pty Ltd v Mineralogy Pty Ltd was heard before the Federal Court of Australia. The dispute involved an application by Mineralogy to amend its defence and introduce a counterclaim, with only nine working days remaining until the scheduled trial date. Sino Iron opposed the application, particularly on the grounds that some proposed amendments posed a serious threat to the trial dates and risked vacating them.

The court was required to determine whether Mineralogy's application should be allowed, considering the potential impact on the trial schedule and the respective positions of both parties. Key issues included the nature and timing of the proposed amendments, the extent of prejudice to both parties, and the availability of any undertakings that could mitigate the prejudice. The court considered the history of numerous changes to the pleadings by Mineralogy, and the lack of a satisfactory explanation for the late introduction of some amendments.

The Federal Court found that while some minor amendments could be allowed, other categories of amendments would pose a significant threat to the trial dates, potentially leading to lengthy delays. Despite Sino Iron's opposition, Mineralogy offered certain undertakings that aimed to alleviate much of the prejudice to Sino Iron. The court acknowledged the prejudice to Sino Iron if the trial was vacated but also recognised the need for some flexibility in the proceedings to ensure justice. Ultimately, the court allowed the application in part, granting permission for certain amendments but denying others that would risk vacating the trial dates.
