What happened: A Queensland court ordered a class action plaintiff to pay $630,000 in security for costs across seven defendants before an insider trading case can proceed
Who's involved: Blue Dog Group (plaintiff shareholder) v Credit Suisse Equities, Argonaut Securities, Euroz Hartleys, Oasis Investments entities, and individual defendants
What's at stake: $630,000 in security for costs; the underlying class claim alleges $33,352,000 in losses, with one defendant putting the class quantum at $580 million
Why it matters: The ruling details how courts size security across defendants with different cost profiles in complex securities class actions - directly relevant to D&O and PI reserving
Where it stands: Proceedings stayed until the plaintiff pays; disclosure phase paused; parties to agree on costs and disclosure orders by October 8, 2026
A company that says it lost more than $33 million when Blue Sky Alternative Investments collapsed has been told to put up $630,000 in cash before its insider trading class action can take another step.
The Supreme Court of Queensland handed down the ruling on September 29, 2026, in a case that spans eight defendants, three brokerages, two offshore investment funds, and two individuals who have each claimed the right not to give evidence that might incriminate them.
Blue Dog Group, a former shareholder of the now-delisted Blue Sky, brought the class action alleging that shares were sold short using inside information in the days before the publication of a critical research report on March 28, 2018. According to the claim, that report valued Blue Sky shares at "77% lower than current prices." Within days, the share price fell from around $11.47 to $5.62 at close on April 5, 2018. Blue Sky was later suspended from the ASX in May 2019 and went into receivership.
The defendants include Credit Suisse Equities (Australia), Argonaut Securities, and Euroz Hartleys - brokers alleged to have executed short sales on behalf of two Oasis Investments entities. The class action alleges the brokers acted with knowledge of inside information, or in circumstances where they could reasonably have worked it out. One defendant submitted the total quantum of the class claim is as high as $580 million.
The court ordered Blue Dog Group to pay security ranging from $70,000 to $200,000 per defendant, with the Credit Suisse entity's share the largest at $200,000. The plaintiff had already paid $375,000 in a first tranche of security to cover the earlier pleadings phase - but every defendant's evidence showed that amount was spent.
The ruling turned on a simple problem: the plaintiff did not hand over financial statements, management accounts, or any detail about who was funding the litigation. When the defendants asked for that information, the plaintiff's solicitor confirmed it would provide security "where it ought to do so" - but gave no financials. No litigation funder is involved. The defendants' only recourse for costs is against the plaintiff itself.
The court found there was "reason to believe" Blue Dog Group would not be able to pay the defendants' costs if ordered to. The plaintiff did not seriously contest this.
Two individual defendants have each claimed the privilege against self-incrimination - essentially, the right to stay silent to avoid exposing themselves to potential criminal liability. Court orders have already excused them from parts of their pleading and document production obligations on that basis.
The plaintiff argued this should reduce or eliminate those defendants' entitlement to security. The court disagreed. Claiming the privilege does not disqualify a defendant from seeking security, and the position the plaintiff advocated "appears to be at odds with the privilege and could operate to undermine" it. Both individuals were awarded security: $90,000 and $70,000 respectively.
The court was blunt about the plaintiff's approach to how much security should be ordered. Blue Dog Group proposed amounts as low as roughly 10% of one defendant's estimated recoverable costs. The court called this an "unfortunate 'race to the bottom'" and said the plaintiff's figures could not properly be called a realistic estimate of recoverable costs, or fair security against the risk of non-payment.
The plaintiff's costs expert was given "little weight." The court found his report was general in nature, based on limited understanding of the proceeding, and in some respects at odds with the evidence. The court preferred the defendants' solicitors' evidence on the scope of the document review ahead, noting that the plaintiff had refused to agree to a narrower, category-based approach to disclosure - which would have reduced costs - and could not now complain about the scale of the exercise.
Blue Dog Group also argued for a "public interest" reduction, contending that insider trading laws serve market integrity and that the case therefore deserved special treatment on costs. The court acknowledged the public interest in prohibiting insider trading but noted the plaintiff's case is about obtaining monetary relief, not an altruistic outcome. A regulator could bring a public interest case, the court observed. That is not what happened here.
The proceeding is now stayed until Blue Dog Group pays the $630,000. The parties have until October 8, 2026, to agree on disclosure orders and costs.
For D&O and professional indemnity claims teams tracking multi-defendant securities class actions, the ruling provides a detailed worked example of how courts calculate security across defendants with different cost structures and legal teams - including the still-uncommon scenario of defendants asserting self-incrimination privilege in a civil proceeding.
The decision is an interlocutory ruling on security for costs. The underlying insider trading allegations have not been tested in court, and no court has made any finding on the merits of the class action.
