Often, the facts of a lawsuit are unclear. One strategy that lawyers often use to prove their version of events is to use an expert witness to corroborate their side’s story. Expert witnesses are individuals who possess knowledge in a field or area that the average person knows little to nothing about. Frequently, both sides in a lawsuit end up utilizing experts who often times have differing opinions about the facts surrounding the lawsuit. But how does a judge or jury determine which expert is correct? Recently, the Fifth Circuit Court of Appeal for the State of Louisiana addressed these questions in a workers’ compensation case.
David Allensworth worked for two different companies, Gulf South Systems (“GSS”) and Grand Isle Shipyard (“GIS”) as a cleaner, cleaning storage tanks containing gasoline, crude oil, diesel fuel, and condensate. One day, Mr. Allensworth visited an urgent care center with complaints of abdominal pain and weight loss. A CT scan revealed a large abdominal mass which was later diagnosed as non-Hodgkin’s lymphoma. A cause of non-Hodgkin’s lymphoma is toxic exposure to benzene with is contained in crude oil and gasoline. Mr. Allensworth filed a lawsuit against GSS and GIS for workers’ compensation benefits claiming that his exposure to benzene while working for the companies caused his non-Hodgkin’s lymphoma. Workers’ compensation pays for an employee’s medical expenses and lost wages when an employee is injured on the job.
At trial, Mr. Allensworth submitted the sworn statement of Dr. Jack Saux as an expert oncologist. Dr. Saux concluded that Mr. Allensworth’s non-Hodgkin’s lymphoma was caused by toxic exposure to benzene, which most likely happened when Mr. Allensworth cleaned his employers’ storage tanks. GIS and GSS countered with its own medical expert, who testified that though there is some association between benzene and lymphoma, there is no evidence that benzene exposure caused Mr. Allensworth’s non-Hodgkin’s lymphoma. The Workers’ Compensation Judge (“WCJ”) concluded that Mr. Allensworth did not prove that his disease was a result of his employment. In doing so, the WCJ noted that Dr. Saux based his opinion on Mr. Allensworth’s statement in which Mr. Allensworth claimed he only wore a regular shirt and overalls while cleaning the tank. It was based only on this statement, and not on an examination, that Dr. Saux concluded that exposure to benzene from Mr. Allensworth’s job likely caused Mr. Allensworth’s disease. The WCJ also noted that the testimony of GIS and GSS’s expert stated that Mr. Allensworth did wear protective equipment when cleaning the tanks.
