Let's say you're an attorney and you have evidence that a particular Administrative Law Judge (ALJ) is prejudiced against a certain group of people. I'm not talking about suspicion or an opinion or belief. I'm talking about specific evidence. I'm not talking about a specific case but let's say you make a Freedom of Information Act request for statistics on the rate at which an ALJ is approving claims depending upon the race of the claimant. You fight the agency for months, if not years, but eventually get the statistics showing a huge disparity. You get a hearing scheduled before this ALJ with a person whose disability claims the agency rarely approves. You file a motion asking for the ALJ to recuse himself or herself attaching the evidence showing the pattern of discrimination. The ALJ refuses. The ALJ goes on to deny the claim but makes sure to remove from the file all the evidence that you submitted showing the pattern of discrimination so the Appeals Council and a federal court can't see it. Can an ALJ do this? Sure, under a recent change to Social Security's HALLEX manual, the ALJ is supposed to remove from the file any evidence you submit concerning the ALJ. If the attorney submits an affidavit to the Appeals Council concerning the ALJ's behavior in the case, that must also be removed from the file.
