 if the tortfeasor that the claimant chose to sue was found to have only contributed 20% of the total increase in risk, then the claimant was awarded damages at 20% of the total loss that he is reckoned to have suffered as a result of the mesothelioma.This meant that if the claimant wanted to be compensated for his full loss, he had to separately sue all tortfeasors.Section 3 effectively reversed the House of Lords decision in "Barker" by making all tortfeasors jointly and severally liable for the mesothelioma so that a claimant can recover compensatory damages for their full loss from any individual tortfeasor that materially increased the risk of mesothelioma.
