Oppression is not unlawfulness: Federal Court reinforces boundary between breach of duty and statutory oppression

The Federal Court has usefully confirmed the relationship between breaches of fiduciary duty and claims of statutory oppression under s 232 of the Corporations Act 2001 (Cth).

In Our Jim & Felicja Superfund Pty Ltd as trustee for the Jim & Felicja Superannuation Fund v Lindenfels Pte Ltd [2026] FCA 307, we acted for the first defendant, Lindenfels Pte Ltd (Lindenfels), in successfully defending the proceedings.

Although the comprehensive dismissal of the proceedings turned primarily on the facts of the case and the specific contracts in question, the Court’s judgment provides two notable takeaways regarding the boundary between breach of duty and statutory oppression, namely:

1. proof of a breach of duty does not shift the onus to the defendant to establish that the impugned conduct was not unfair — the burden remains on the plaintiff asserting oppression throughout; and
2. whether conduct is oppressive is not materially assisted by any inquiry into whether that conduct is otherwise unlawful or in breach of a fiduciary duty. 

Practical implications 

This decision reinforces that oppression and breach of duty are distinct causes of action serving different purposes. 

An attempt to bootstrap an oppression claim by establishing a breach of fiduciary or statutory duty will not necessarily assist a claimant. The essential criterion remains commercial unfairness, and it must be independently established on its own terms. 

Parties defending oppression claims should be alert to attempts to conflate the two. They can take comfort that the court will assess impugned conduct through the prism of whether it was, objectively, commercially unfair to the members in question.

The who's who

The claim was brought by minority shareholders of Batchfire Resources Pty Ltd (Batchfire) – a coal mining company which acquired the Callide coal mine in 2016 – against its majority shareholder Lindenfels and a former director. 

Although factually dense, the plaintiffs’ claim was grounded in alleged breaches of fiduciary duty by Batchfire’s marketing agent in the sale of Batchfire’s export coal at an alleged undervalue. The marketing agent was a related entity of Lindenfels.

The alleged relationship between unlawfulness and oppression

The plaintiffs submitted that once the alleged breaches of duties were established, the evidentiary burden shifted to the defendants to demonstrate that the conduct was not unfair and oppressive. 

The plaintiffs also argued that unfairness would be "more readily established" where unlawful conduct had occurred.

The Court's findings

Halley J rejected both propositions.

On onus, his Honour held that the burden of proof always rests on the party asserting oppression. A plaintiff who proves breaches of fiduciary or statutory duties does not thereby shift the onus to the defendant to prove the conduct was not unfair. 

On the relevance of unlawfulness, the court found that the ultimate question in every oppression case is whether the impugned conduct was oppressive or unfairly prejudicial to or unfairly discriminatory against members of a corporation. While the conduct may also be unlawful, his Honour did not accept that any such determination elevates the seriousness of the conduct for the purposes of determining whether it was oppressive. The impugned conduct must be considered through the lens of the principles governing oppression and a finding that conduct was unlawful does not require or even assist the court in that assessment.

Importantly, the court also affirmed that the converse holds true: conduct may be oppressive even if it is entirely lawful.
