Securities, Investment Company and Derivative Litigation

  • Obtained the dismissal under the Securities Litigation Uniform Standards Act of 1998 (“SLUSA”) of three putative class actions alleging breach of fiduciary duty by the independent trustees of closed-ended investment companies in connection with the redemption of hundreds of millions of dollars in auction rate preferred shares. An appeal taken in one of the cases resulted in a ground-breaking decision of the United States Court of Appeals for the Seventh Circuit applying SLUSA to state law claims purporting to allege breach of fiduciary duty notwithstanding the absence of express allegations of fraud and plaintiff’s disavowal of any intention to assert a claim based upon misstatements or omissions of fact. Mr. Rotunno successfully opposed a petition for certiorari which sought Supreme Court review on the ground that the Seventh Circuit’s decision assertedly created a conflict among the federal Circuit Courts of Appeal.
