The Supreme Court of Queensland has stayed an insider trading class action after ordering the plaintiff to post $630,000 in security for costs across seven defendants, finding there was reason to believe the company could not meet an adverse costs award.

As reported by Insurance Business Australia, the plaintiff, Blue Dog Group, never produced financial statements or management accounts despite repeated requests from the defendants about who was funding the case. The plaintiff's solicitor offered only general assurances that security would be provided "where it ought to do so."

Notably, no litigation funder is involved in the proceeding. That absence is central to the outcome: with no funder standing behind the claim, the defendants' costs exposure ran to the plaintiff company's own balance sheet, which was never disclosed. The court found there was reason to believe Blue Dog could not pay the defendants' costs — a proposition the plaintiff did not seriously contest.

The proceedings have been stayed and disclosure paused until security is posted.

The decision is a reminder that funding transparency cuts both ways. Defendants increasingly press for disclosure of funding arrangements as a route to security applications, and an unfunded corporate plaintiff that declines to open its books may find that silence treated as evidence of impecuniosity. For claimants without institutional backing, the practical effect is that a security order can stop a class action before the merits are reached.

More than 1,000 additional claimants in England and Wales have joined a group action against cryptocurrency exchange Binance and its founder Changpeng Zhao, bringing the total to roughly 2,700 consumers globally. KP Law, which is running the claim, describes it as the first of its kind in the United Kingdom.

As reported by The Law Society Gazette, the announcement coincided with the Financial Conduct Authority opening its authorisation gateway for the UK's new crypto asset regulatory regime, which comes into force on 25 October 2027. Binance is expected to apply under that regime.

The claim was filed in the High Court in June, and claims issued now exceed £250 million. Claimants allege that Binance sold high-risk leveraged and derivative products — including leverage, futures and options — to UK users without FCA authorisation between late 2019 and early 2020. They contend those products are specified investments under the Financial Services and Markets Act 2000, which may only be sold by authorised persons.

Binance has more than 300 million customers worldwide. Individual claimants are reported to have lost sums ranging from tens of thousands to millions of pounds.

KP Law partner Hannah Sharp noted that Binance Markets Limited was barred from carrying on regulated activity in the UK in 2021.

No litigation funder is identified in connection with the claim. Opt-in group actions of this scale nonetheless depend heavily on book-building and costs cover, making the financing arrangements behind the claim a point of interest as the case progresses.
