Yesterday, as I write this, the Biden Admin announced this:
Executive Order on the Establishment of the Presidential Commission on the Supreme Court of the United States | The White House
The commission will have at most 36 members. "Members of the Commission shall be distinguished constitutional scholars, retired members of the Federal judiciary, or other individuals having experience with and knowledge of the Federal judiciary and the Supreme Court of the United States (Supreme Court)."
What this commission is to be doing:
(a) The Commission shall produce a report for the President that includes the following:
(i) An account of the contemporary commentary and debate about the role and operation of the Supreme Court in our constitutional system and about the functioning of the constitutional process by which the President nominates and, by and with the advice and consent of the Senate, appoints Justices to the Supreme Court;
(ii) The historical background of other periods in the Nation’s history when the Supreme Court’s role and the nominations and advice-and-consent process were subject to critical assessment and prompted proposals for reform; and
(iii) An analysis of the principal arguments in the contemporary public debate for and against Supreme Court reform, including an appraisal of the merits and legality of particular reform proposals.
(b) The Commission shall solicit public comment, including other expert views, to ensure that its work is informed by a broad spectrum of ideas.
(c) The Commission shall submit its report to the President within 180 days of the date of the Commission’s first public meeting.
Very general, and no mention of specific proposals, like term limits or expanding the Court.
