Fraud and Ponzi Schemes

Harley represented more than seventy investors, who collectively lost $190 million investing with Ft. Lauderdale lawyer Scott Rothstein, who ran a Ponzi scheme, based on selling fictitious structured settlements. Typical recoveries in these cases range from 10 -30%. Harley and his team recovered over 95% of losses, and their attorney’s fees.

Corporate Disputes

Harley successfully represented a New York investor, and his closely held corporation, in a $2.5 billion dispute with his CEO (and nephew) over entitlement to the proceeds of the sale of his oil and gas venture. After the sale, the CEO sued in multiple courts, arguing entitlement to half the proceeds, on the theory that he was a general partner of the venture. Harley and his team defeated the claims entirely, while obtaining sanctions against the CEO for discovery abuses, and recovering a favorable monetary settlement of the counterclaim.

Legal Malpractice Defense

Harley successfully represented a large Florida law firm, which was sued for malpractice relating to a resort development. He successfully argued that the claim was legally defective, resulting in a resolution of the claim, which included a public statement by the plaintiff admitting the law firm had done nothing wrong and affirming that the legal services rendered by the law firm were excellent.

Class Actions

On behalf of 700,000 physicians, and their medical societies, including Texas Medical Association, the California Medical Association and others, Harley acted as co-lead counsel in a national class action against the major HMOs including Aetna, Cigna, Humana and others for systematically denying doctors reimbursement for services provided to patients by down coding medical services through the use of their computerized reimbursement procedure. The case resulted in the recovery of billions of dollars both in actual cash payments to the doctors, and improved reimbursement procedures and dispute resolution methods.
