Strategic approach to complex issues

Zack's litigation practice encompasses a wide range of high-stakes matters for clients across industries, including financial services, manufacturing, real estate, technology, health care and energy. His experience spans commercial contract disputes, real estate litigation, employment matters, financial services disputes, antitrust litigation and complex fraud litigation.

Zack has served as lead counsel for one of the world’s largest industrial gas companies in litigation against the Russian Federation's state-owned gas company. The case stemmed from the unlawful seizure of assets in Russia, raising novel geopolitical issues involving global sanctions and the property rights of foreign businesses.

Zack is well-versed in handling complex financial fraud litigation, such as matters stemming from the Madoff bankruptcy. These cases require navigating international corporate restructuring, cross-border discovery and multiparty coordination.
