Representative Experience

  • Representation of a global energy client adverse to a significant landowner in coastal Vermilion Parish.  The plaintiffs sought more than $119 million in compensatory damages, plus punitive damages, for alleged negligence, unreasonable and excessive use of mineral lease rights, strict liability, and willful and wanton conduct in connection with handling and storage of wastes.  Plaintiffs claimed that our client had violated environmental regulations, which they claimed resulted in widespread contamination of soil, groundwater, and sediment that required hundreds of acres of wetlands to be excavated, among other remedies.  Plaintiffs also claimed that the alleged environmental contamination had infiltrated crabs and other seafood, making these products unsafe for human consumption.  After a three-week trial in 2015, the jury adopted the environmental remediation plan presented by our client and found that our client had not engaged in any negligent or willful conduct and had not exceeded any of its rights under the applicable mineral and surface leases.
