Walt Cubberly is a partner at Williams Hart & Boundas, LLP in Houston, and among the city’s injury lawyers he stands apart for a reason that is easy to verify: when some of the most closely watched injury litigation in the country needed leadership, courts picked him. California judges appointed Cubberly co-lead counsel in both the Uber and Lyft coordinated sexual-assault proceedings (the Uber JCCP and Lyft JCCP), placing him at the front of litigation on behalf of the many women pursuing claims against both rideshare giants. Judges do not hand that kind of responsibility to attorneys who have not already proven they can carry it.
At his core, Cubberly is a courtroom lawyer. He is open about the fact that he loves trying cases to juries, because a jury is the one force with genuine power to make a large corporation answer for the harm it causes. That philosophy produced a concrete result in Kelly Martel v. Monsanto Company, where the jury returned a multi-million dollar verdict for Ms. Martel after concluding that Monsanto and the maker of its surfactant caused her non-Hodgkin’s lymphoma. Winning a case like that means translating dense scientific and corporate evidence into a story twelve ordinary people find true — a skill no settlement mill develops.
His academic and professional pedigree is unusually strong for a plaintiff’s lawyer. Cubberly earned his bachelor’s degree from the University of Texas at Austin in 2004, where he was a Liberal Arts Scholar, then graduated magna cum laude from the University of Houston Law Center in 2009 — tenth in his class, inducted into the Order of the Coif and the Order of the Barons, and honored with the Lex Award for Constitutional Law. After law school, he spent the 2009–2010 term clerking for Justice Phil Johnson of the Texas Supreme Court, an inside education in how appellate judges actually decide cases that very few injury attorneys ever receive. He has published scholarship on constitutional adjudication in state courts, and he is admitted to federal district courts spanning Texas, California, Missouri, and Pennsylvania — a footprint that matches a genuinely national practice.
Cubberly is the kind of lawyer to call when the defendant is big and the stakes are high: a dangerous product, a corporation that put profit ahead of safety, or a survivor of sexual assault connected to a rideshare platform. He represents people going up against companies with deep pockets and large defense teams, and his record shows he does not blink at either.
