His broad litigation practice encompassed environmental law, and defense of toxic tort, consumer product, asbestos, and pharmaceutical products liability claims.

Mr. Leone had special expertise in environmental litigation and counseling, including issues relating to Superfund, natural resource damages, hazardous waste, hazard communication, groundwater, surface water, wetlands, clean air, state environmental laws, and environmental auditing.  He also litigated parallel tort actions seeking personal injury, property damage, and/or medical monitoring damages.  He has successfully defended such cases whether filed individually, as part of a mass tort, or as a class action.

Mr. Leone served as counsel for Norfolk Southern in Avondale Mills v.

Mr. Leone’s litigation experience also included representing a large manufacturer in multiple state CERCLA enforcement actions, Natural Resource Damage recovery actions, and related personal injury/property damage cases in New York, North Carolina, and South Carolina.  He defended Consumer Product Safety Act litigation, including penalty cases and one that was resolved through an unprecedented joint industry-wide/CPSC mediation.  He also defended numerous clients in asbestos personal injury and property damage claims, including a client’s Havner challenges in connection with the consolidated Texas statewide asbestos docket and defense of civil conspiracy and other collective liability claims.
