For many months, correspondence to the ALJ assigned to hear a case, had to be addressed, “Dear Administrative Law Judge.” Why was it not addressed to the Judge by name? Social Security had adopted a policy of keeping secret the identity of the ALJ until you appeared at the hearing office for the hearing. So, you had to address correspondence to the title, and not to the Judge. It was a foolish, unncessary policy, from the start, always, and will be for the next 16 days.
On April 20, the rule of the secret judge evaporates, as it should, forever.
You will again know the name of the Administrative Law Judge assigned to hear your case, in advance of your hearing. You will know what to expect and it will be one fewer thing to worry about.
