Again, I'll answer as a lawyer, and then I'll try to move on to comprehensive things.
Benefit of the doubt is basically an onus of evidence rule that lies in many aspects of the legislation dealing with veterans affairs. In a nutshell, the legislator is saying forget the normal rules of preponderance in civil cases. In other words, in civil cases when you're a plaintiff, the evidence you bring forward has to be preponderant. It has to be higher than that of the individual you're suing or pursuing a case against.
What the benefit of doubt does in the situation of a tie, say, where the evidence is relatively equal on both sides, is that the legislator says you go to the vet; forget the normal preponderance issue as being determinative of whether or not you win your case.
To try to write that into a bill of rights might be just too complex to do, to my mind, unless you understand these various preponderance issues. I think it would be more useful to simply reiterate the principle that from an evidentiary point of view, the proposition that somebody brings to the table when they're presenting their case, there is a presumption that the evidence is there to grant. In other words, it's the bill of rights itself that is the message, versus that simple evidentiary rule.
So I think it's a question of choice. If you want to build a very complex evidentiary preponderance rule into the bill of rights, or simply state in the bill of rights that this is done in order to make sure that the veteran has available to him every recourse possible and imaginable, and that the system is to deal with the claim or the representation accordingly, I think it's probably more efficient from a perception point of view and a practical point of view also.
