Subsection 17(2) is quite clear:
' ...if the employee dies without leaving dependants, compensation is not payable in respect of this injury'
Refer to Part 1.11 [2] for explanation of the meaning of 'dependants'.
Note that a 'dependant' as defined by S4(1) of the SRCA must be 'dependent' upon the employee for economic support.
