## Facts

- Macquarie Infrastructure Investment Management Ltd prepared and circulated a prospectus seeking public investment in a Sydney toll road project.
- The prospectus included statements and projections about expected traffic volumes and road usage.
- Truth About Motorways Pty Ltd, a community group opposing or scrutinizing the project, alleged the prospectus was misleading about projected traffic and risk disclosure, contrary to Trade Practices Act 1974 (Cth) provisions (including s 52).
- The group was not an investor, did not plan to invest, and alleged no personal financial loss from the prospectus.
- The group sought declaratory and injunctive relief (including corrective advertising) and also pursued a writ of prohibition aimed at restraining conduct connected with the securities issue.

## Issues

1. Whether proceedings brought by a plaintiff without a “direct or special interest” can constitute a constitutionally cognizable “matter” within Chapter III federal jurisdiction when a statute grants standing to seek relief.
2. Whether the Trade Practices Act validly confers standing on “any other person” to seek declarations and injunctions for alleged misleading or deceptive conduct, including by a non-investor community group.
3. Whether Chapter III requires “reciprocity of right and duty” or a traditional special-interest requirement as a precondition to standing and federal jurisdiction.

## Decision

- The High Court upheld the constitutional validity of the Trade Practices Act provisions conferring standing on “any other person” to seek injunctive and declaratory relief for contraventions.
- The Court held that the proceeding involved a Chapter III “matter” despite the applicant’s lack of a direct financial stake or special interest.
- Truth About Motorways fell within the statutory grant of standing and could maintain the action; federal jurisdiction existed to hear the claim.
- The Court indicated that, even where standing exists, discretionary control over remedies remains available to prevent inappropriate use of proceedings.

## Legal Principles

- A constitutionally cognizable “matter” may exist where there is a real controversy about alleged breach of a statutory norm and a claim for judicial determination through remedies such as injunctions or declarations.
- Chapter III does not impose a universal requirement that a plaintiff show a traditional private-law “special interest” or “reciprocity of right and duty” if Parliament has validly conferred a right to seek relief.
- Broad statutory standing provisions allowing “any other person” to apply for injunctions and related remedies can be constitutionally valid and effective.
- Standing analysis in statutory enforcement contexts is closely connected to the statutory remedial scheme; lack of personal loss does not necessarily defeat a claim for statutory injunctive or declaratory relief.
- Courts retain discretion to refuse relief where the connection to the controversy is too slight, where there is abuse of process, or where relief would not serve the statutory purpose.

## Conclusion

The High Court confirmed that Parliament may confer wide standing to seek declarations and injunctions to enforce statutory prohibitions on misleading or deceptive conduct, and that such litigation can involve a Chapter III “matter” even when the applicant lacks a direct or special interest, subject to judicial discretion over remedies.
