What it's about

The Court granted the Department of Commerce’s request for a stay and directed the government to file an expedited petition seeking further review, so the Department prevailed on the immediate request.

This was a procedural step in litigation over the 2020 Census citizenship question, not a final decision on the broader dispute.

Question presented

Whether this Court should grant extraordinary mandamus relief to halt discovery in district court litigation regarding the 2020 Census.

What the Court decided

Holding

The application for stay (18A375) presented to JUSTICE GINSBURG and by her referred to the Court is granted in part and denied in part. The application is granted as to the order of the United States District Court for the Southern District of New York dated September 21, 2018, which is stayed through October 29, 2018 at 4 p.m. The application is denied as to the orders of the United States District Court for the Southern District of New York dated July 3,2018 and August 17, 2018. If the applicants file a petition for a writ of certiorari or a petition for a writ of mandamus with respect to the stayed order by or before October 29, 2018 at 4 p.m., the stay will remain in effect until disposition of such petition by this Court. Should the petition be denied, this stay shall terminate automatically. In the event the petition is granted, the stay shall terminate upon the sending down of the judgment of this Court. The denial of the stay with respect to the remaining orders does not preclude the applicants from making arguments with respect to those orders. Justice Gorsuch, with whom Justice Thomas joins, concurs in part and dissents in part. (Detached opinion )

From the opinions

“Normally, judicial review of an agency action like this is limited to the record the agency has compiled to support its decision.”

— Justice Gorsuch(dissent)

What's next

The Department of Commerce could file a petition for Supreme Court review or a mandamus petition (a request for an order directing the lower court to act) by October 29, 2018, at 4 p.m. A timely filing would keep the pause in place until the Court finished acting on it; if the Court denied (refused) the petition, the pause would end automatically.
