In SEPTA v. Workers’ Comp. Appeal Bd. (Hansel), Employer petitioned for review of a decision that granted Claimant’s fatal claim petition related to the suicide of her husband (Decedent). Employer argued the Workers’ Compensation Judge (WCJ) erred in concluding that Decedent’s suicide was unintentional and, therefore, not compensable. Employer also argued that the WCJ erred in not applying what is known as the mental-mental standard, which requires a showing of abnormal working conditions in connection with Decedent’s psychiatric illness. The Pennsylvania Commonwealth Court affirmed, holding that there was substantial evidence to support the WCJ’s findings. Also, the Court found that the mental-mental standard was inapplicable.
