In 2007, which document invokes the jurisdiction of the Workers' Compensation Appeals Board (WCAB)?

• A. Dwc-1
• B. Letter of representation
• C. Declaration of readiness to proceed
• D. Application for adjudication

Answer: (D)

The key idea is that the WCAB’s authority over a claim begins the moment a formal case is started. In California workers’ compensation, that formal start comes from filing an Application for Adjudication. This pleading lays out who’s involved, the injury, and the issues to be decided, and once it’s filed the WCAB gains jurisdiction to hear the case, issue notices, set hearings, and move the matter forward.

The other documents don’t start the case. A Declaration of Readiness to Proceed (often seen as a later procedural step to move toward a hearing) signals that the parties are ready to proceed but does not create jurisdiction. A letter of representation is simply notice that an attorney represents a party and has no effect on initiating the dispute. So, the document that invokes WCAB jurisdiction is the Application for Adjudication.
