Hogan had $34 million stashed in a Swiss bank account for the Carthage Trust, which was run by the Geneva financial services firm Strachans for almost two decades, reports The Sydney Morning Herald.
Australian clients of the financial services company had been named in the Australian Taxation Office's $430 million Wickenby tax probe in 2004, and Egglishaw is believed to be the mastermind behind the tax evasion scheme.
Hogan vows to "take every step possible in every country possible" to hold Egglishaw responsible for his lost millions. There is already an international arrest warrant on the corrupt advisor, nicknamed "the bowler hat Englishman," for setting up elaborate corporate tax havens.
Legal documents filed by Hogan's lawyer Schuyler Moore in California District Court claim Eggishaw "absconded with or spent all" the cash. Moore wrote to Egglishaw's lawyer in Geneva to say the firm is "aiding and abetting" the advisor's criminal actions.
"The Carthage Trust's beneficiary [Hogan] is not going to stand idly by in the face of this theft, and he is going to take every step possible in every country possible to hold Egglishaw, Strachans, you, and your firm liable and brought to account."
