Representative Matters

  • Represented a developer and financer of solar energy projects in disputes in both the U.S. District Court for the District of New Jersey and the Superior Court of New Jersey arising from three municipal project financings for the design and construction of dozens of solar power electric generating facilities on government-owned properties in Morris, Somerset, and Sussex counties. Successfully obtained a judgment discharging more than $40 million in Municipal Mechanics’ Liens levied against public project funds and then secured an affirmance of that decision following an expedited appeal. Defeated multiple attempts to freeze tens of millions of dollars in proceeds from solar renewable energy certificates, section 1603 grants from the U.S. Department of the Treasury, and revenue derived from the sale of solar electricity.  Negotiated extremely complex global settlement agreements that resolved disputes with the engineering, procurement, and construction contractor, county improvement authorities, and county governments.

  • Represented one of the world’s largest banks in an action brought in the U.S. District Court for the Southern District of New York to recover an unpaid investment banking fee.  Negotiated a settlement following motion practice in which the court struck several of the adversary’s affirmative defenses and dismissed the adversary’s counterclaim against the firm’s client for breach of contract.

  • Represented major mattress retailer in a putative class action alleging violations of both the New Jersey Consumer Fraud Act and the New Jersey Truth-in-Consumer Contract, Warranty and Notice Act. Negotiated a favorable class-wide settlement prior to resolution of the plaintiff’s motion for class certification.

  • Co-authored, and served as counsel of record for, an amicus brief filed in the Supreme Court of the United States on behalf of a group of eleven members of the U.S. Senate and four members of the U.S. House of Representatives in the most closely watched case of the 2013-2014 Supreme Court term.

  • Appointed by the U.S. Court of Appeals for the Third Circuit to serve as counsel for an inmate challenging the conditions of his confinement in a Delaware state prison.  Among other things, the suit challenges a prison policy that requires all isolation inmates to be strip searched every eight hours, regardless of whether they have any opportunity to obtain contraband.
