For an injury in 2007 what invokes the jurisdiction of the WCAB?

• A. Letter of Representation.
• B. Application for Adjudication of Claim.
• C. DWC-1.
• D. Declaration of Readiness to Proceed.

Answer: (B)

Invoking the WCAB’s jurisdiction happens when someone files the formal claim with the board—the Application for Adjudication of Claim. This petition starts the case and gives the Workers’ Compensation Appeals Board authority to hear and decide it. The injury date (2007) doesn’t change that rule. A Letter of Representation only tells the WCAB who will represent a party; it doesn’t start proceedings. A Declaration of Readiness to Proceed is used later to move an already active case toward a hearing, not to initiate the case. The form often used to file the application is the DWC-1, but the essential action is filing the Application for Adjudication of Claim.
