  • U.S. Sugar Litigation. Ongoing – Acting as lead counsel for U.S. Sugar Corporation in defending a putative class action alleging that the industry's practice of burning sugar cane fields before harvesting causes personal injury and primary damage.
  • Secured a trial victory for Nicor in a suit brought by the City of Evanston, IL alleging that contamination caused by Nicor migrated into the city and contaminated its water mains, putting the health of the city's 77,000 residents at risk. The city demanded an injunction that would require Nicor to conduct a detailed study and to prepare to replace miles of aging city water mains at a cost of hundreds of millions of dollars. After a two-week trial that included more than 10 experts, a federal trial court ruled in favor of Nicor, determining that there was no evidence that the water mains were contaminated by Nicor and no evidence that the city's water posed a risk to its residents.
