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. If a claimant does so, then the sued tortfeasor has the right to claim a contribution from any and all other tortfeasors that also materially increased that risk, proportionate to the extent by which each tortfeasor increased that risk.
