Finally, the Supreme Court stops Trump

Friends,

Some good news to end the year on. The Supreme Court today blocked Trump from sending the National Guard into the Chicago area — finally setting a limit to Trump’s executive power.

The decision was 6 to 3, with Roberts, Kavanaugh, and Barrett joining the three liberal justices in a majority. Alito, Gorsuch, and Thomas dissented.

The court said that Trump had “failed to identify a source of authority that would allow the military to execute the laws in Illinois,” and, presumably, other states.

Trump had said he needed the troops to protect federal immigration agents at a detention facility.

Existing law allows a president call on the military if there is a foreign invasion or “danger of a rebellion,” or if the president is unable to execute federal laws with “regular forces.”

Trump’s Justice Department argued that “regular forces” means federal civilian law enforcement, such as Immigration and Customs Enforcement officers. And protests in Illinois prevented the president from enforcing immigration laws using ICE officers alone.

But a majority of the court found that the term “regular forces” refers to the nation’s standing military — and the authority to call the National Guard into federal service is meant as a backstop for the Army, Navy and other “regular” military forces.

The court noted that a president’s ability to use the military this way is limited to “exceptional” circumstances. That’s because another federal law, known as the Posse Comitatus Act, sharply restricts the use of the standing military to conduct domestic law enforcement.

Bingo.

Because the decision came in the form of an unsigned order on the court’s emergency docket, that’s about all we can know of the court’s logic.

But this is a big deal.

Trump has won short-term rulings in more than 20 other emergency appeals this year — allowing him to follow through on an array of policies that lower courts had blocked (such as laying off thousands of federal workers, ending programs that had allowed immigrants to remain in the country legally, and terminating research grants and foreign aid).

Trump’s Justice Department had argued that this case “falls in the heartland of unreviewable presidential discretion.”

Wrong. The Supreme Court just put up a fence limiting that heartland. And finally a bulwark constraining a president’s power.

It’s about time.
