Duty to assist:

BVA Citation Nr: 0723526

The Board notes that, as a general rule, VA has a duty to 
assist a claimant in developing the facts pertinent to his or 
her claim, and to notify him or her of the evidence necessary 
to complete an application for benefits. The Veterans Claims 
Assistance Act of 2000 (VCAA), which became law on November 
9, 2000, redefined the obligations of VA with respect to the 
duty to assist and included an enhanced duty to notify a 
claimant as to the information and evidence necessary to 
substantiate a claim for VA benefits. However, the United 
States Court of Appeals for Veterans Claims (Court) has held 
that the VCAA does not apply to claims of CUE in prior Board 
decisions or in prior rating decisions. See Parker v. 
Principi, 15 Vet. App. 407, 412 (2002); Livesay v. Principi, 

15 Vet. App. 165, 178-79 (2001).
