Austral Mining Construction Pty Ltd (In Liquidation) v NZI Capital Corporation Limited

This case concerns an application for special leave to appeal to the High Court of Australia. The applicant, Austral Mining Construction Pty Ltd (In Liquidation), sought leave to appeal a decision of the Full Court. The first respondent was NZI Capital Corporation Limited, and the second respondent was Sogelease Australia Limited, which indicated it would abide by the Court's decision. The dispute revolved around a bill of sale and its effect on the applicant's claim to title.

The primary legal issue before the High Court was whether a particular bill of sale constituted an "instrument" as defined by the *Bills of Sale and Other Instruments Act 1955-1986* (Qld). If it was such an instrument, the applicant's failure to comply with section 19 of the *Bills of Sale Act* would prevent it from gaining title. A secondary issue concerned the interpretation of the term "debenture" and whether the Full Court's construction was consistent with previous authorities, potentially causing difficulties in other contexts.

The applicant argued that the Full Court's decision on the definition of "instrument" had broader implications for the application of various provisions of the *Bills of Sale Act* to standard form bills of sale given by companies. The applicant contended that the Full Court's interpretation of "debenture" was out of line with prior case law. The Court noted that if the applicant failed on the primary question of whether the bill of sale was an instrument under the relevant Act, the other questions would not arise. The applicant conceded that registration under the *Bills of Sale Act* was unnecessary due to the provisions of the *Companies Code*. The Full Court's judgments, while unanimous in conclusion, adopted different approaches, particularly in their reliance on established authorities concerning the nature of debentures.
