Bill was lead counsel for Lumber Liquidators, the nation’s largest specialty retailer of hardwood flooring, in over 130 class action cases in 28 states, a U.S. Consumer Product Safety Commission investigation, a California Air Resources Board enforcement action, and several state attorney general investigations. These matters arose from a 60 Minutes report alleging that the Company’s laminate flooring exposed consumers to excessive amounts for formaldehyde. Morrison successfully defended Lumber Liquidators in a trial based on California’s chemical warning law, Prop. 65, resolved the U.S. CPSC investigation without the need for a traditional recall, and resolved the remaining class action matters on favorable terms.
In the largest environmental bankruptcy in recent years, Bill was the lead environmental counsel for Debtor Maxus Energy Corporation. Maxus declared bankruptcy as it faced nearly $14 billon of environmental liabilities flowing from several legacy contaminated sites, including remediation of the Pasaaic River Superfund Site in New Jersey, the largest site in the United States.

Won a victory for client LAWA in a trial against a supplier that breached a contract to provide LAWA with highly specialized Airport Rescue Firefighting (ARFF) vehicles. After years of delay, and after receiving millions of dollars in payment from LAWA, the supplier delivered defective trucks that not only failed to meet LAWA’s performance, safety, and regulatory requirements, but put the safety of airport firefighters and the traveling public at risk. The supplier also asserted claims against LAWA. During trial, the 12-member jury unanimously found in favor of our client, finding that LAWA was not liable for breach of contract or good faith and fair dealing claims brought by the plaintiff.
In a scientifically intensive trial, Bill led the development of experts in toxicology, food consumption, geology, agriculture, and food safety required to defend 10 major baby food and fruit juice brands from claims that they had excessive levels of lead in their products. After a four-week trial, the judge entered judgment in favor of the defense, finding that levels in the products fell below the threshold required by California’s Proposition 65 — one of the most significant trial court decisions in the statute’s 25-year history. The California Court of Appeal upheld the trial court’s decision.

Bill represented The Coca-Cola Company in a lawsuit filed by the California Attorney General and Los Angeles City Attorney alleging unfair competition, defective design, public nuisance, and violation of Proposition 65, stemming from the unauthorized sale of Mexican Coca-Cola in California.
