The Financial Services Authority (FSA) has brought cases against Arch Financial Products and the company's chief executive Robin Farrell and chief operating officer Robert Addison.
All three cases have been referred to the Upper Tribunal, though no date has been set for a hearing.
Farrell said in a statement: "We fundamentally disagree with the FSA's approach in this matter and this is why the cases have been referred to the Upper Tribunal."
Addison declined to comment, and the FSA did not respond to requests for comment.
The three cases are in addition to other legal action being taken against the firm, Addison and Farrell regarding the failed Arch Cru absolute return fund range.
In July an £160m claim was issued by SPL - which administers the Arch Cru fund range as it is being wound down - against Addison and other former directors Peter Radford and Neal Meader, and former administrators Bordeaux Services.
In April, Farrell was hit with a £27m claim by SPL that he "acted dishonestly in assisting Arch in relation to each of Arch's breaches of its fiduciary duties".
Farrell denies the claims.
In January it was revealed Arch is being sued for £150m by the board of 18 Guernsey-listed investment vehicles for not exercising a fundamental care of assets and failing to account for "substantial secret profits".
A High Court writ claims Arch ignored conflicts of interest by using money from the cells to buy shares in Arch and Cru Investment Management, which marketed the funds in the UK
