URGENT REPORT: City of Petaluma v. WCAB (Lindh): Apportionment to Risk Factors

In 2004, the Legislature made a diametric change to the law on apportionment. Labor Code § 4663 was amended to allow apportionment to causation. Under this statute, employers are only liable for the percentage of permanent disability directly caused by the injury arising out of and in the course of employment.
