Missouri’s Top 20 Law Firms 2023: Armstrong Teasdale
Staff Report//December 15, 2023//

Armstrong Teasdale’s appellate team includes Tom Weaver, Jeff McPherson and former Missouri Supreme Court Judge William Ray Price Jr., among others.
Among the numerous examples of their high-profile cases, they won a ruling in the Court of Appeals Eastern District in 2020 that slashed about half of a $4.69 billion verdict against Johnson & Johnson on claims that its talcum power products caused cancer.
In 2019, they won a Missouri Supreme Court ruling that plaintiffs can’t use the state’s joinder rules to establish venue where it otherwise wouldn’t exist, affecting several mass tort cases with out-of-state plaintiffs filed in St. Louis.
In 2014, the firm won a partial victory in a tough case in the Eastern District, which, due to a legal error in the jury instructions, threw out two thirds of a $358.5 million award regarding lead poisoning from a Missouri smelter.
