17.02 EXPLANATORY: Jones Act--Causation is a legal term used in maritime law that applies when a seaman is injured on the job. It requires employers to provide a safe working environment and equipment, and if the seaman is injured or killed due to the employer's negligence, then the employer is liable for compensating the seaman or his/her dependents. There are two types of causation that can be used to prove liability under the Jones Act—actual causation and proximate causation. Actual causation requires demonstrating that the employer's negligence was the cause of the injury, whereas proximate causation requires demonstrating that the employer's negligence was the proximate cause of the injury.
