What a Federal Judge's Ruling on an Acting U.S. Attorney Appointment Means

A federal judge ruled that Alina Habba's appointment as acting U.S. attorney violated federal law

On January 15, 2025, U.S. District Judge Loren AliKhan in New Jersey found that Alina Habba's appointment to serve as acting U.S. attorney for the District of New Jersey was unlawful. The judge determined that the appointment violated the Federal Vacancies Reform Act, a law that sets strict rules about who can temporarily fill senior government positions when they become vacant.

Habba had been appointed to the role without meeting the requirements the law sets out. Specifically, the judge found she lacked the necessary qualifications: she had not been a federal judge, had not held the position of U.S. attorney before, and had not been confirmed by the Senate to a position in the Department of Justice. The ruling did not remove her from the position immediately, but it established that the appointment itself was legally invalid.

This case matters because it clarifies how the Vacancies Reform Act actually works in practice, and it shows what happens when a federal agency appoints someone to a temporary senior role without following the law's requirements.

Key Takeaways

• The Federal Vacancies Reform Act limits who can serve as acting U.S. attorney and requires them to meet specific prior experience or confirmation standards.
• A federal judge found Alina Habba did not meet those standards because she had never been a federal judge, a U.S. attorney, or a Senate-confirmed Department of Justice official.
• The ruling does not automatically end the appointment but establishes that it violated federal law and may affect cases or decisions made under her authority.
• This decision could influence how the Department of Justice fills acting positions in the future and may prompt review of other temporary appointments made under similar circumstances.

What the Federal Vacancies Reform Act actually requires

The Federal Vacancies Reform Act, passed in 1998, exists to prevent the executive branch from filling high-level positions indefinitely without Senate confirmation. It allows agencies to appoint someone to act in a vacant senior role for a limited time, but only if that person meets one of three conditions.

First, the person must have been a federal judge. Second, they must have previously held the position that is now vacant (in this case, U.S. attorney for that district). Third, they must have been confirmed by the Senate to a position in the same agency — in this case, the Department of Justice. Alina Habba met none of these conditions. She was a private attorney and Trump campaign lawyer, not a judge, not a former U.S. attorney, and not a Senate-confirmed DOJ official.

The law also sets time limits. An acting appointment can last up to 210 days, with some exceptions that can extend it. The point is to prevent an agency from treating a temporary role as a permanent one without going through the Senate confirmation process.

Why Judge AliKhan ruled the appointment unlawful

The judge's reasoning was straightforward: the statute says what it says. Habba did not fit any of the three categories of people who can legally serve as acting U.S. attorney. The Department of Justice had appointed her anyway, which meant the appointment violated the plain language of the law.

The judge also noted that the purpose of the Vacancies Reform Act is to ensure that temporary appointments do not become a way around the Senate confirmation process. Allowing someone without the required background to serve as acting U.S. attorney would undermine that purpose.

This was not a close call or a matter of interpretation. The law sets out specific requirements, and Habba did not meet them. The judge applied the law as written.

What happens to cases and decisions made under her authority

The ruling creates uncertainty about the legal status of actions taken while Habba served as acting U.S. attorney. Any decision, prosecution, or official action she took in that role could potentially be challenged on the grounds that she lacked the authority to make it.

This does not automatically void everything she did. Courts will likely examine each case individually. Some decisions might stand if they would have been made the same way by a lawfully appointed acting U.S. attorney. Others might be overturned or sent back for reconsideration. Defendants in cases she prosecuted may file motions arguing that her lack of authority means the charges should be dismissed.

The Department of Justice may also review pending cases and decisions to determine which ones need to be reconsidered or reassigned to a lawfully appointed official.

How this affects future acting appointments in the Justice Department

This ruling serves as a reminder to the Department of Justice that the Vacancies Reform Act is enforceable and that courts will strike down appointments that do not meet the statute's requirements. It does not change the law itself, but it reinforces what the law actually means.

Going forward, the DOJ will need to ensure that anyone appointed to act as U.S. attorney meets at least one of the three statutory conditions. This may limit the pool of candidates available for temporary appointments, particularly when the department wants to appoint someone from outside the traditional career path.

The ruling also signals that similar challenges could be brought against other acting appointments in the federal government if they do not comply with the Vacancies Reform Act. Agencies across the executive branch may review their own temporary appointments to ensure they meet the law's requirements.

What the broader legal landscape looks like

Courts have been increasingly willing to enforce the Vacancies Reform Act in recent years. This is not the first time a judge has found an acting appointment unlawful, and it likely will not be the last. The statute has become a tool that challengers use to contest the authority of temporary officials.

The ruling also reflects a broader tension in administrative law: how much flexibility should the executive branch have in filling positions quickly, and how much should the Senate confirmation process constrain that flexibility? The Vacancies Reform Act tries to strike a balance, but that balance is tested whenever an agency appoints someone who does not fit the statute's categories.

This case is one data point in an ongoing conversation about presidential power, Senate oversight, and the proper way to fill vacant government positions.

Frequently Asked Questions

Does this ruling mean Alina Habba has to leave her position immediately?

The judge's ruling established that the appointment was unlawful, but it did not automatically remove her from the position. The Department of Justice could appeal the decision, or the position could be filled through a different legal mechanism. The practical effect depends on what the DOJ does next.

Can people who were prosecuted by Habba use this ruling to get their cases dismissed?

Possibly. Defendants can argue that Habba lacked the authority to prosecute them because her appointment was unlawful. A court would then decide whether that lack of authority is grounds for dismissal or whether the case can proceed under a lawfully appointed U.S. attorney. Each case will be different.

What does the Federal Vacancies Reform Act actually say about who can serve as acting U.S. attorney?

The law says the acting official must be either a federal judge, someone who previously held that same position, or someone confirmed by the Senate to a position in the Department of Justice. Alina Habba met none of these requirements, which is why the judge found her appointment unlawful.

Could the Department of Justice reappoint Habba in a different way?

Only if they found a legal basis for doing so under the Vacancies Reform Act. Since she does not meet any of the three statutory categories, a reappointment would likely face the same legal challenge. The DOJ would need to appoint someone who meets the law's requirements.

Does this ruling affect other acting appointments in the Trump administration?

Not directly, but it establishes a precedent that courts will enforce the Vacancies Reform Act. Other acting appointments could be challenged if they do not meet the statute's requirements. The ruling serves as a warning that temporary appointments must comply with federal law.
