Experience

  • In the Financial Oversight Board and Management Board for Puerto Rico, Case No.17-BK-4780-LTS (D.P.R.), involving the disputed confirmation of a proposed plan of adjustment concerning $8 billion in defaulted bonds issued by the Puerto Rico Electric Power Authority (PREPA), successfully conducted key cross-examinations of the Board’s experts at trial.
  • In Citibank, N.A. v. OWS Administration, LLC, 227 A.D.3d 601 (1st Dep’t 2024), on behalf of a large group of bondholders with collective investment in excess of $300 million, argued appeal and obtained reversal of lower court judgment concerning the interpretation of the bond indenture.
  • Achieved trial victory on behalf of Mar-Bow Value Partners (Jay Alix) against worldwide consulting giant McKinsey & Co, Inc. Mar-Bow prevailed without presenting a single affirmative witness, with Michael conducting some of the key cross-examinations. The victory was the culmination of a multi-pronged, multi-jurisdictional effort to bring McKinsey into compliance with bankruptcy disclosure laws which it had been flouting for decades.
  • In Zohar CDO 2003-1 v. Patriarch et al., No. 17-cv-0037-WHP (S.D.N.Y.), obtained dismissal at the pleading stage of nearly a dozen claims brought against MBIA for hundreds of millions of dollars by investor Lynn Tilton and her affiliate, Patriarch Partners. In granting MBIA’s motion, the Court found that Tilton and Patriarch had “made significant use of creative license” in pleading their claims, and that “[w]hen viewed under the bright light of context,” the alleged “misstatements and omissions reveal themselves as nothing more than ... smoke-and-mirrors.”
  • In Tilton v. MBIA, Inc., et al., 68880/2015 (Westchester Comm. Div.), a dispute over a $103 million CLO transaction, served as co-trial counsel and conducted critical cross-examination of Plaintiff’s CLO expert. The case settled on favorable terms for the client just before submission to the jury.
  • In Cappel v. JenCap Holdings LLC et al., C.A. No. 2020-0598-PAF, obtained trial victory in Delaware Chancery Court enforcing informational rights on behalf of investor in post-merger company managing over $7 billion in insurance premiums.
  • Obtained judgment in favor of client Kingsland Holdings Limited, which is serving as Independent Third Party in exercising remedies of United Airlines, Inc. associated with contracts effectuating loan obligations in excess of $500 million (loan secured by shares of Colombia-based Avianca Holdings SA); judgment allows Kingsland to move toward a foreclosure sale on the Avianca Holdings SA shares securing the loan obligations.
  • Securing dismissal of a civil RICO case seeking in excess of $100 million in damages against the third largest beverage alcohol distributor in the US, and obtaining affirmance of the dismissal on appeal to the Second Circuit. In addition, aggressively pursued offensive strategy, including successful claims for advancement and indemnification of legal fees against the plaintiff.
  • Securities fraud and related claims for private equity fund, resulting in summary judgment in excess of $100 million, $725,000 in discovery sanctions against defendant and award of attorney fees.
  • In Bank of New York Mellon Trust Co., NA v. Morgan Stanley Mortgage Capital, Inc., obtained high eight-figure settlement on eve of trial for leading real estate investment company damaged by breach of environmental warranty concerning securitized commercial mortgage loan.
  • Breach of contract and business tort action for former president of AIG Global Real Estate; claims pertained to profit shares in all AIG real estate investments worldwide and reached favorable settlement the evening before trial in the Southern District of New York.
  • In NML Capital, Ltd. v. Republic of Argentina, No. 12-105-cv(L), represented consortium of financial firms holding more than $1 billion in Argentinian exchange bonds; obtained stay from the US Court of Appeals for the Second Circuit enabling the Republic’s exchange bondholders to receive $3 billion in payments.
  • Litigated specific performance and breach of contract case for private equity fund arising out of defendant’s refusal to close on sale of company; court entered summary judgment in favor of client, resulting in favorable settlement.
  • Co-tried and obtained multimillion-dollar award for executive who conceived and introduced the Refco / Thomas H. Lee leveraged buyout.
  • Represented private equity firm in securities fraud case in New York federal court; replaced client’s existing counsel after original complaint was dismissed, developed new claims, survived motions to dismiss, and obtained favorable eight-figure settlement. Defended co-founders of prominent social media firm in case by former associate claiming stock valued in the nine figures; won critical motion for injunctive relief by plaintiff, resulting in ruling that plaintiff was unlikely to succeed on the merits.
