Cases Tried or Otherwise Taken to Judgment

Trial counsel for Pratt & Whitney in environmental tort cases involving more than $1 billion in alleged property damage and personal injury claims arising out of the declaration of a "cancer cluster" in a neighborhood near Pratt & Whitney's West Palm Beach facility.

Slawson Exploration Co. v. Department of Interior (D.N.D.)

The Department of the Interior has since issued a final agency order denying a Native American tribe's challenge to Slawson's drilling permits.
