Joshua Braver Challenges Broad Judicial Deference in Insurrection Act Cases

What changed

Professor Joshua Braver argues that the history of laws governing domestic military deployments points against giving presidents broad judicial deference. His argument challenges the Ninth Circuit’s “highly deferential” approach in the case over Donald Trump’s 2025 federalization of California’s National Guard and extends to the broader debate over the Insurrection Act.

Why it matters

The Ninth Circuit struck down the federalization, but its reasoning may matter almost as much as the result. By giving the president significant leeway to judge conditions on the ground, the court adopted a standard that related cases involving Portland and Chicago also echoed.

That creates a sharp legal tension. Congress wrote statutes governing when the military can be used domestically, including 10 U.S.C. §12406 and the Insurrection Act. Braver’s point is that courts should not treat presidential judgment as nearly conclusive when deciding whether those statutory conditions exist.

The stakes are larger under the Insurrection Act, which is described as the more powerful tool for domestic deployment. If courts grant the president “very significant deference,” the practical boundary may shift from what the statute permits to what the president says the situation requires.

My read is that the central question is not whether courts should respect the executive branch during a crisis. It is whether statutory limits mean anything if the president’s factual assessment receives almost automatic weight. The final legal effect of the Ninth Circuit’s ruling, and how the Supreme Court will handle the deference issue, remain unsettled.
