Stanley Marsh (Marsh) petitions this court to review the lawfulness of an opinion of the Workers Compensation Appeals Board (WCAB). (Lab. Code, § 5950; Cal. Rules of Court, rule 57.) We are called upon to determine the applicability of the new apportionment provisions enacted by the 2004 workers compensation reform legislation under Senate Bill No. 899 (SB 899) to a decision pending before the WCAB on reconsideration.
