The Supreme Court’s October 1 miscellaneous order set up a heavy fall docket: justices granted review in Rhoney v. Barbosa da Cunha on mandatory immigration detention and in Missionaries of St. John, Inc. v. Frederic on a Religious Land Use and Institutionalized Persons Act zoning question, SCOTUSblog and Reuters report. Separately, the Court denied a stay application tied to Thornell v. Jensen, clearing the way for a receiver to begin running Arizona prison healthcare around October 19, with Ninth Circuit merits argument still set for December 7, Arizona Mirror and SCOTUSblog’s case page note.

The detention case will test how far the administration can mandate custody for certain noncitizens pending removal proceedings — a core Trump second-term enforcement pillar. The RLUIPA grant is limited to the religious-zoning question presented. On Arizona, Justice Elena Kagan’s chambers handled the stay paperwork; the denial means the district court’s receivership machinery can start while the appeal continues. Prisoner-rights groups call the receiver overdue after years of inadequate care findings; state officials warn of cost and control losses.

Backstory: October’s “long conference” leftovers often reshuffle the argument calendar into 2027. Overnight packages the grants and the Arizona stay denial as confirmed order-list facts — not argued merits outcomes.

Rhoney’s detention question sits at the center of Trump’s interior-enforcement agenda; a government win would harden mandatory custody rules that immigrant-rights clinics say swell ICE bed demand already under GAO scrutiny. The RLUIPA zoning grant is narrower but watched by churches and mosques fighting local permit dens. Arizona’s receiver start date around Oct. 19 is the near-term operational deadline on Thornell.
