  Notable Representations

  • Successfully represented Switzerland-based Chartwell Asset Management in SEC Insider Trading case.  In February 2012, after pursuing months of discovery, the SEC dismissed its claims against Chartwell.  The SDNY directed that over $9 million deposited with the court be returned to Chartwell with interest.
  • Represented Isidoro Garbarino in notable Customs prosecution in SDNY.  Obtained sentence of time served for Mr. Garbarino even though he had been a fugitive for more than 20 years.
  • Counsel of record in United States Supreme Court for the New York Counsel of Defense Lawyers in an amicus brief supporting petitioner in Alleyne v. United States.
  • Represented internet advertising firm Betawave in a securities class action brought by private equity firm Sunrise Equity Partners.  Claims arose from the PIPE transaction which took Betawave public.  Plaintiffs first filed in federal court, but we convinced Plaintiffs to voluntarily dismiss. Sunrise re-filed in state court and Justice Kornreich granted Betawave's motion to dismiss with prejudice.
  • Represented Google and Twitter in Second Circuit in matter involving applications of the “hot news misappropriation” doctrine.
  • Represented Joint Provisional Liquidators of the Bermuda hedge fund Parkcentral Global Hub in a matter adverse to JPMorgan Chase.  Successfully overturned ex parte pre-judgment attachment of more than $200 million.

  • Represented Intuit in a case brought by Muriel Siebert & Co. after the dissolution of a joint discount on-line brokerage.  Siebert sought over $44 million in damages, claiming fraud, breach of fiduciary duty and breach of contract.  After we defeated a motion to disqualify Quinn Emanuel (which went all the way to the New York Court of Appeals in a published decision, 8 N.Y.3d 505) and narrowed much of Siebert's claim on a motion to dismiss, Siebert agreed to dismiss its suit against Intuit with prejudice. Intuit paid nothing to Siebert.
