If damages recoverable by a person in respect of an injury or death as a result of an accident to which Division 1 of Part 10 applies were reduced or an amount recoverable by a person by way of indemnity in respect of an injury or death was reduced by reason that the person who was injured or died was partly responsible for the injury or death, the amount payable to the Commission under section 105 is reduced by the amount that bears, in relation to the amount paid by the Commission, the same proportion as the amount by which the damages recovered were, or the amount recovered by way of indemnity was, reduced bears to the damages or amount by way of indemnity that would have been recovered if the person who was injured or died had not been partly responsible for the injury or death.
