American Tort Reform Association releases report on scientific claims in mass tort litigation

The American Tort Reform Association released a report on Jan. 31 documenting how a coordinated network of trial lawyers, researchers, and advocacy groups uses manufactured scientific claims to drive mass tort litigation against vaccine manufacturers and other industries.

The topic is significant as it addresses the intersection of legal strategies, scientific research, and public health policy. The report alleges that certain parties create the appearance of scientific consensus to support lawsuits in areas such as acetaminophen litigation, vaccine safety disputes, and climate attribution science. According to ATRA’s report titled The Trial Lawyer Playbook: The Junk Science Play, "researchers, labs, and expert witnesses create the appearance of scientific consensus to funnel claims into courtrooms. The report highlights three active areas: acetaminophen litigation, vaccine safety disputes, and climate attribution science," according to ATRA’s report.

Political donations from major trial law firms are also highlighted in related findings. Eight major trial law firms identified by the Alliance for Consumers gave roughly $25 million in political donations from 2017 through 2024. In 2024 alone, the firms donated $4 million, with 99% going to Democratic candidates or aligned committees, the AFC reported.

Financial impacts of tort litigation are also noted. The U.S. tort system cost $529 billion in 2022, equal to 2.1% of GDP and $4,207 per American household. If trends continue, ILR projects costs could approach $1 trillion by 2030, putting additional pressure on biotech and pharmaceutical companies according to the U.S. Chamber of Commerce Institute for Legal Reform (ILR).

The American Tort Reform Association is described as a national coalition of businesses, municipalities, and professional organizations that advocates for civil justice reform. It publishes an annual "Judicial Hellholes" report ranking jurisdictions by litigation climate and has tracked regulation-by-litigation practices since its founding in 1986.
