The Trump administration has spent nearly two years testing how far executive power can stretch before something snaps. On Tuesday, in a Los Angeles courtroom, something finally did—though the snap was more procedural creak than constitutional thunderclap.

U.S. District Judge André Birotte Jr. ruled that Bill Essayli, the U.S. Attorney for the Central District of California, has been "unlawfully serving" in his role because he was never confirmed by the Senate. The decision disqualifies Essayli from the case at hand—a prosecution that will now need to find new leadership—and raises uncomfortable questions about every action his office has taken since he assumed the post.

The Appointments Clause, briefly explained

The Constitution is admirably clear on this point: "principal officers" of the United States require Senate confirmation. U.S. Attorneys, who wield enormous prosecutorial discretion over federal cases in their districts, have traditionally been understood as principal officers. Essayli, a former Republican state assemblyman and reliable Trump ally, was installed without that confirmation. The administration's apparent theory was that he could serve indefinitely in an "acting" capacity, a workaround that has become increasingly popular across the executive branch.

Judge Birotte disagreed. His ruling doesn't mince words: Essayli's service is "unlawful," full stop. The judge stopped short of voiding every prosecution Essayli's office has touched, but the implication hangs in the air like smoke after a controlled burn.

Why this matters beyond one courtroom

The Central District of California covers Los Angeles, Orange County, and five other counties—roughly 20 million people and some of the most consequential federal prosecutions in the country. Essayli's office has been active in immigration enforcement, public corruption cases, and the administration's broader campaign against sanctuary policies. If his authority was defective from day one, defense attorneys across the district now have a potent new argument.

More broadly, the ruling is a reminder that the Senate confirmation process, however creaky and politicized, exists for a reason. The Framers wanted principal officers to face at least a modicum of scrutiny before wielding federal power. The Trump administration's preference for acting officials—across agencies, not just Justice—has systematically avoided that scrutiny. Judge Birotte's decision suggests courts may not tolerate the practice indefinitely.

The limits of the victory

Still, one should not overstate what happened Tuesday. The ruling applies to one case in one district. Essayli remains in his office, at least for now, and the Justice Department will almost certainly appeal. The Supreme Court's conservative majority has shown little appetite for constraining executive authority, and the Appointments Clause has not exactly been a growth area for constitutional litigation. The administration could also simply nominate Essayli for Senate confirmation, daring Democrats to block him and reaping the political benefit either way.

Our take

This is a win for constitutional formalism, which is another way of saying it is a win for the boring but essential idea that process matters. Bill Essayli may be a perfectly capable prosecutor; that is beside the point. The question is whether the executive branch can staff itself with loyalists while bypassing the one check the Constitution explicitly requires. For one afternoon in Los Angeles, the answer was no. Whether that answer holds—or spreads—will depend on judges less willing to look away, and a Senate less willing to be ignored.
