About David

David Byrne has been with Beasley Allen since February 2001.  He is a principal and trial attorney in the firm’s Mass Torts Section, handling claims against pharmaceutical and medical device companies.

At present, David works on federal litigation related to defective hip replacement devices and state court cases involving contaminated baby food products.


David earned his undergraduate degree from The Citadel in 1989 and his law degree from the Cumberland School of Law in 1992.

Following graduation, David served as a Deputy Alabama Attorney General and as a law clerk to U.S. District Judge Robert Varner and Alabama Court of Criminal Appeals Judge John M. Patterson. He then entered private practice with another Montgomery, Alabama law firm before joining Beasley Allen.

Notable Cases

Since joining the firm’s Mass Torts Section, David has been actively involved in litigation related to hormone replacement therapy medication, transvaginal mesh devices, hip replacement devices, Xarelto blood-thinning medication, baby food heavy metal contamination, and benzene-contaminated sunscreen products. David previously served as a trial attorney in the firm’s Toxic Torts Section where he handled numerous complex environmental cases in state and federal courts throughout the United States.  During that time, he handled cases involving wide-ranging topics such as drinking water contamination, toxic air emissions, contaminated waste-water discharges, toxic exposure, improper landfill activities, petroleum spills, medical monitoring claims, and soil and groundwater contamination.

California Hormone Replacement Therapy Class Action

David served as co-lead class counsel in a California federal court case involving Wyeth Pharmaceuticals and its hormone replacement therapy medications Premarin, Prempro, and Premphase. In September 2020, the court approved a $200 million class settlement that provided substantial relief to affected consumers throughout California.

J&J Sunscreen Class Action (MDL 3015)

Davis was appointed class co-counsel in the Johnson & Johnson Aerosol Sunscreen Multidistrict Litigation Proceeding (MDL No. 3015). This MDL involved benzene-contaminated sunscreen sprays sold by Johnson & Johnson under the company’s Neutrogena and Aveeno product lines. In February 2023, the U.S. District Court for the Southern District of Florida (the MDL court) granted final approval of a nationwide class action settlement agreement. Among other things, the settlement compensated consumers for their qualifying purchases of the affected products and imposed testing restrictions on Johnson & Johnson that will help prevent future benzene contamination problems.

BP Oil Spill

David was actively involved in litigation related to the BP Oil Spill disaster. During the BP Oil Spill litigation, David assisted the State of Alabama and numerous counties and cities in Alabama and northwest Florida that suffered damage.

Tennessee Valley Authority Coal Ash Spill

David also served as co-lead counsel in the federal trial against the Tennessee Valley Authority over the company’s catastrophic release of more than 1 billion gallons of coal ash sludge from an impoundment at its Kingston Fossil Plant. The verdict for the plaintiffs in that case provided enormous monetary relief to hundreds of area residents.  Additionally, more than $1 billion has been spent on clean-up costs at the site since the date Beasley Allen filed its original lawsuit.

New Jersey Water PFOA Contamination

Further, David served as co-lead class counsel in a New Jersey federal court case involving PFOA contamination of public and private drinking water supplies near the DuPont Chambers Works facility in Deepwater, NJ. In 2011, the Court approved a class settlement that provided water filtration systems and other relief to over 15,000 residents.

Carbon Black Pollution in Alabama and Oklahoma

David also served as co-lead trial counsel in cases involving carbon black pollution in Alabama and Oklahoma that resulted in a $20 million-plus verdict and other significant settlements for several municipalities, businesses, and local residents.

Anniston Alabama PCB Contamination

In 2003, David was involved in the landmark $700-million toxic tort settlement with Solutia, Monsanto and Pharmacia over PCB contamination in Anniston, Alabama — the largest environmental settlement in the country at the time.

Other Cases

Additionally, David has assisted clients in obtaining multi-million dollar settlements or verdicts in other types of cases involving food-product franchises, the Federal Tort Claims Act, accounting malpractice, motor vehicle franchise disputes, consumer fraud, the funeral services industry, premises liability, and insurance agent contract disputes.
