REYNA I. SANCHEZ vs. UNILEVER, INSURANCE COMPANY OF THE STATE OF PENNSYLVANIA, ALBERTO CULVER COMPANY, ACE AMERICAN INSURANCE
The WCAB granted reconsideration and rescinded the WCJ's decision to allow further proceedings. The employer's stipulation of employment for the entire cumulative trauma period was invalid as they only represented one insurer. Crucially, the date of injury must be determined under Labor Code § 5412 to establish liability under § 5500.5 for the correct employer(s). The applicant's election against Unilever was permissible under § 5500.5(c), and any future awards for jointly liable employers must be joint and several.
