Representative Matters

  • Representation of the Official Stanford Investors Committee (“OSIC”) in long-running litigation arising out of R. Allen Stanford’s Ponzi scheme, one of the largest financial frauds in U.S. history. Friedman Kaplan and co-counsel prosecuted investor and estate claims in Texas federal court against five banks for, among other things, aiding and abetting violations of the Texas Securities Act and knowing participation in Stanford’s breach of fiduciary duty. OSIC’s recovery of $1.6 billion in settlements follows years of vigorous litigation involving complex issues of U.S., Canadian, English, and Swiss law, extensive motion practice, and nearly a hundred fact and expert depositions in the U.S. and abroad.

  • Representation of a holding company of car dealerships in defense of a breach of contract and related tort claims brought by minority members and former officers in New York Supreme Court.
  • Representation of Caesars Entertainment Corporation in defense of federal and chancery court lawsuits brought by various creditor groups alleging that certain transactions violated the terms of bond issuances and the Trust Indenture Act. 
  • Representation of asset management companies in the Northern District of Illinois in defense of claims brought by an index provider for trademark infringement, trade secret misappropriation, breach of contract, tortious interference, and fraud.
