The VA "reasonable doubt doctrine" is confusing. Its not the same as in a criminal trial. The standard is When there is an approximate balance of positive and negative evidence regarding any issue material to the determination of a matter, the Secretary shall give the benefit of the doubt to the claimant.
Instead of "reasonable doubt" doctrine, it should be called the "benefit of the doubt" doctrine. A much more accurate term.
Your better off arguing facts with the VA then trying to argue law...your claim needs to present enough evidene so that it passes the VA's standard (quoted above in bold)
To win this, you must supply some evidence that, when weighed against all the evidence in your case, forces the VA to give you the "benefit of the doubt". Evidence is evidence. Your statement is evidence. The statement from the corpsman is evidence.
You do need to link the event to the medical condition...I am not a doctor so do not know if this condition can present later (more than one year later) or not...but if it can...if its possible that the event in the Navy
caused this but it simply took awhile to present...if you can show the event, and show you the condition now, I think you pass the test.
Let me know if you have more questions
