The Department of Veterans Affairs found a vet disabled. Social Security doesn't think they need to give any explanation why they disagreed and found him not disabled. In fact, to my ears, they sound a bit arrogant about it. This may sound reasonable to some at Social Security. Those of us who represent claimants think the agency has picked a fight it probably won't win in federal court. If you think it's clear that the agency will win on this issue, I'd suggest you take a step back and try to look at this from the perspective of a federal judge. And saying that federal judges just don't understand Social Security doesn't get you anywhere.
By the way, yes, I know, this guy probably got some bad advice. Overestimating the strength of one's hand can be a problem for both sides.
