Benefit of Doubt:

BVA Citation Nr: 0711173

The regulations provide that it is the defined and 
consistently applied policy of the VA to administer the law 
under a broad interpretation, consistent, however, with the 
facts shown in every case. When after careful consideration 
of all procurable and assembled data, a reasonable doubt 
arises regarding service origin such doubt will be resolved 
in favor of the claimant. By reasonable doubt is meant one 
which exists because of an approximate balance of positive 
and negative evidence which does not satisfactorily prove or 

disprove the claim. 38 C.F.R. § 3.102 (2006).
