Mason v. Texas Employers' Insurance Ass'n
Charlie Mason, a 53-year-old truck driver, died of a heart attack while working a night shift in freezing weather. His widow filed a worker's compensation claim, asserting the heart attack was an occupational disease or an accidental injury resulting from his strenuous work conditions and long hours. The jury determined Mason had a heart attack but found it did not occur in the course of his employment. The appellate court affirmed the trial court's 'take nothing' judgment, finding no error in the jury instructions regarding the definition of 'occupational disease' or the refusal to include a specific definition of 'accidental injury'.
