Shown below is a selection of Jonathan’s engagements.

  • Successful representation of former officers of a US public company specializing in innovative green energy technology against a liquidating trustee's claim of securities fraud. A statute of limitations argument under the discovery prong of the Supreme Court's 2010 Merck v. Reynolds decision persuaded the court that dismissal of Katten's clients was warranted; the US Court of Appeals for the Second Circuit unanimously affirmed.
  • Representation of a Cayman Islands fund defendant in a shareholder derivative complaint alleging breach of fiduciary duties. The case raised unique questions under Cayman Islands law that had only been addressed by a handful of US courts, and never by a federal or state appellate court. Successfully persuaded the judge to dismiss the action for lack of standing under Cayman Islands law, and crafted the brief that won affirmance in a case of first impression among US appellate courts.
  • Representation of a financial institution seeking recovery against principals of a borrower under a "bad boy" guaranty; Katten obtained summary judgment and the decision was affirmed on appeal.
