Toxic Tort & Environmental Litigation


Liskow & Lewis represents national and local companies in a broad range of toxic tort, environmental and worker exposure cases.

Typical toxic tort cases involve personal injury and/or property damage claims from chemical spills or industrial releases. These matters may range from a single worker alleging occupational exposure to noise resulting in hearing loss to thousands of consolidated or class action claimants alleging exposure to chemicals or substances.

Our firm represents clients in cases involving tort allegations arising out of damage to land from industrial and oil and gas operations. We also represented potentially responsible parties in CERCLA cost recovery and in private toxic tort claims involving Louisiana “Superfund” sites.

Our lawyers have been active in thousands of cases involving plaintiffs who claim to have been occupationally exposed to asbestos, silica, benzene, carbon monoxide, hydrogen sulfide, vinyl chloride and other substances on the job. These claims sometimes date as far back as the 1930s.

Because Louisiana courts apply the law at the time of the alleged exposures to such cases, the attorneys in this area are skilled in applying pre-comparative fault principles as well as current comparative fault laws. Many of these occupational exposure cases also involve claims for medical monitoring.

The firm’s primary clients in this area include employers, executive officers, premises owners, and certain equipment manufacturers and others who may be defendants in occupational disease litigation.

Criminal Defense

Over the last three decades, our firm has successfully defended corporate and individual clients in a wide range of matters involving state and federal air, water and hazardous waste laws.

Our environmental criminal defense practice group combines the talents of our environmental lawyers with the experience of the firm’s white collar criminal lawyers. We help clients with internal investigations, search warrant response planning, compliance programs, grand jury investigations and the defense of criminal charges.

For companies involved in criminal investigations, we advocate communicating early with prosecutors to effect a speedy and successful resolution. When charges are unavoidable, our lawyers are adept at handling procedural and substantive environmental regulatory defenses.


We frequently represent individuals and companies facing significant environmental liabilities in coverage litigation against insurance carriers.

Our lawyers handle coverage actions and issues involving pollution exclusions, owned property exclusions, waste disposal exclusions, late notice, policy triggers, occurrences and damages.

When clients face complex environmental insurance coverage disputes, our lawyers represent them in state and federal courts at both the trial court and appellate levels.

The interpretation of insurance policies varies from state to state, and even within courts of the same state. Because of our reputation and experience in this area, out-of state counsel, on behalf of clients, seek our advice on the selection of appropriate forums and legal analysis of coverage issues.
