Representing clients in class and derivative actions, Bill's approach is to minimize his clients’ overall cost through careful strategic planning, dispositive motions and aggressive negotiation. Only three of the many securities class actions he has defended have resulted in any settlement payment by his client or its carrier. Of his nearly 100 motions to dismiss securities class, mass or derivative actions since 1996, more than 90 percent were granted in their entirety (most with prejudice), while others were granted in part or led to a successful motion for summary judgment.

John Ansbro Partner

New York

John litigates a wide range of commercial disputes, including financial services litigations involving RMBS, disputes in the wind and solar power industries across a host of contractual issues, construction disputes, long-term take-or-pay and liquidated damages disputes, force majeure, bankruptcy litigation, insurance recovery, and commercial real estate foreclosure.

These include force majeure matters across jurisdictions and industries, including Energy & Infrastructure, Pharmaceuticals, Financial Services, Real Estate, Hospitality, and Retail.

John litigates significant, high stakes matters. For example, in 2017 on behalf of his client Hemlock Semiconductor Corp., in a case of first impression in Michigan, on appeal John won the dismissal of an attempt by a Japanese conglomerate to avoid $1.4 billion in purchase obligations on the theory that alleged acts by the Chinese Government constituted an “act of government” under the parties’ force majeure provision. The Michigan Bar Journal declared it one of the top 10 business cases of 2010-2019. In 2019, one of the very few RMBS actions to be tried, John was trial counsel for Credit Suisse Securities USA in a $700 million dispute in the Supreme Court of New York. At trial he handled the defense expert in the critical area of loan underwriting.
