Which filing invokes the WCAB's jurisdiction for an injury occurring in 2007?

• A. Notice of injury
• B. Application of adjudication of claim
• C. Petition for temporary relief
• D. Request for mediation

Answer: (B)

In California workers’ compensation, the WCAB gains jurisdiction when a formal case is started with a filing that initiates the adjudication. That vehicle is the Application for Adjudication of Claim. This pleading lays out the injured worker, the employer/insurer, the injury, and the compensation sought, and it triggers service, hearings, and the Board’s authority to decide the claim.

A Notice of Injury is simply notifying the employer and insurer about the accident and does not itself create a WCAB case. A Petition for Temporary Relief is a request for interim benefits within an existing adjudication, not the act that starts the Board’s jurisdiction. A Request for Mediation is a pathway to settlement and, by itself, does not instantiate the formal adjudication of the claim.
