The Supreme Court has agreed to hear Carr v. Saul and Davis v. Saul, two cases presenting the issue of whether the federal courts can consider Lucia objections to Administrative Law Judges (ALJs) having heard cases before the Social Security Administration when those objections had been raised administratively. The Supreme Court held in Lucia v. SEC that ALJs were unconstitutional since they had not been appointed by the agency head. Since that time they have been.
My opinion is that it's nuts to expect claimants to have raised Lucia objections when the Social Security Administration's stated position was that it wouldn't consider Lucia objections. It's also nuts because the Supreme Court had previously held that it was not necessary to raise other sorts of objections in Social Security cases administratively before raising them in the federal courts.
It's possible but I imagine unlikely that the new Solicitor General for the Biden Administration could decide to settle these cases before they're heard.
