Not a lawyer, but have had experience with administrative law judges. Despite the title, they are NOT judges, and are not part of the judicial branch of government. In the Social Security Administration, for example, after you apply for disability benefits, and are rejected, and appeal, and are rejected again (which is what usually happens if there is any doubt), the Social Security administrative law judge hears the next appeal (and usually overturns the decision appealed to them). Administrative law judges are a part of the bureaucracy, and limits on them have no bearing on limitations of judicial review.
As I was telling Tex I could not recall any specific cases, but something
came to mind. Dornan may have mentioned the Railroad act in his
discussion of the subject. Can't say with certainty though.
