The Washington Post is reporting this as breaking news a few minutes ago:
The Trump administration moved to reallocate the money earlier this year, after Congress denied the president’s full request for border wall construction funds. The Sierra Club and a coalition of border communities sued, arguing that President Trump had violated federal law.
I haven’t found this elsewhere; I’ll be monitoring and updating as soon as I know more.
More info as of 5 minutes ago: It’s 5-4, unsigned ruling.
The application for stay presented to JUSTICE KAGAN and by her referred to the Court is granted. Among the reasons is that the Government has made a sufficient showing at this stage that the plaintiffs have no cause of action to obtain review of the Acting Secretary’s compliance with Section 8005. The District Court’s June 28, 2019 order granting a permanent injunction is stayed pending disposition of the Government’s appeal in the United States Court of Appeals for the Ninth Circuit and disposition of the Government’s petition for a writ of certiorari, if such writ is timely sought. Should the petition for a writ of certiorari be denied, this stay shall terminate automatically. In the event the petition for a writ of certiorari is granted, the stay shall termi-nate when the Court enters its judgment.
Short translation: Plaintiffs did not have proper standing to challenge the transfer of funds. It appears that the House was not a party to the suit, though it filed a brief in support.
I find the phrase “among the reasons” peculiar and unnerving.
