KRS 342.680: Presumptions in the case of death or of physical or mental inability to

testify.

In any claim for compensation, where the employee has been killed, or is physically or

mentally unable to testify as confirmed by competent medical evidence and where there is

unrebutted prima facie evidence that indicates that the injury was work related, it shall be

presumed, in the absence of substantial evidence to the contrary, that the injury was work

related, that sufficient notice of the injury has been given, and that the injury or death was

not proximately caused by the employee's intoxication or by his willful intention to injure

or kill himself or another.
