- In 2014, obtained the reversal by the Second Circuit Court of Appeals of a U.S. District Court ruling in a cost-recovery action brought under the federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).

The decision clarified a number of important land use issues left unanswered by a 30-year-old Court of Appeals decision and cleared the way for our client to continue its quarrying operations for decades to come.
- In 2008, litigated the enforceability of the attorney approval contingency clause in a form residential real estate contract utilized throughout upstate New York. In a decision hailed by real estate brokers and attorneys throughout the state, the New York Court of Appeals agreed that the attorney approval contingency clause could be exercised for any reason the attorney deemed appropriate and that no justification for that decision need be given.
