No. The National Guard cannot refuse to federalize. Once the President issues a lawful order calling Guard members into federal service under Title 10, command shifts to the federal military chain by operation of law, a governor’s objection carries no legal weight, and individual Guard members who disobey face court-martial under the Uniform Code of Military Justice. The Constitution, federal statutes, and Supreme Court precedent all point the same direction, and they have for decades.
That doesn’t mean governors have never resisted. Several have. But resistance is a political posture, not a legal defense, and the distinction matters enormously for any Guard member trying to figure out where their obligations actually run.
The Moment Command Transfers
Guard service happens in one of three duty statuses, and the status determines who gives orders.
- State Active Duty: the governor activates Guard members under state law for a local emergency. They are state employees, paid by the state.1National Guard Bureau. National Guard Duty Statuses
- Title 32: the federal government pays, but the governor keeps command. Routine training and many domestic missions fall here.2Office of the Law Revision Counsel. 32 USC Chapter 3 – Personnel
- Title 10: the President activates Guard members for federal service. Command transfers entirely to the federal chain. Guard members become functionally identical to active-duty soldiers or airmen.3Office of the Law Revision Counsel. 10 USC 12405 – National Guard in Federal Service: Status
Title 10 activation strips the governor of authority over the affected Guard members. There is no formal gubernatorial approval step, no veto, no delay mechanism. From the moment they are required to respond to the federal call, they belong to the federal chain of command.
Where the President’s Authority Comes From
Article I, Section 8 of the Constitution gives Congress the power to call forth the militia to enforce federal laws, suppress insurrections, and repel invasions, and to organize, arm, and discipline the militia when in federal service.4Legal Information Institute. Article I Section 8 Clauses 15 and 16 – The Militia Congress has translated that power into two main statutory tools.
The Insurrection Act (10 U.S.C. §§ 251–253) gives the President three pathways to federalize the Guard. Section 251 lets a state request federal help against insurrection. Section 252 lets the President federalize units from any state, without any state’s consent, when rebellion or obstruction prevents enforcement of federal law through the courts.5Office of the Law Revision Counsel. 10 USC 252 – Use of Militia and Armed Forces to Enforce Federal Authority Section 253 lets the President act unilaterally when domestic violence or conspiracy deprives people of constitutional rights and the state fails to protect them.6Office of the Law Revision Counsel. 10 USC 253 – Interference with State and Federal Law Two of the three pathways require no state approval.
Separately, 10 U.S.C. § 12406 authorizes the President to call the Guard into federal service when the United States is invaded or in danger of invasion, when there is rebellion or danger of rebellion, or when the President cannot execute federal laws with regular forces alone.7Office of the Law Revision Counsel. 10 USC 12406 – National Guard in Federal Service: Call This provision was invoked in June 2025, when the President ordered at least 2,000 Guard personnel into federal service to protect federal personnel and property.8The White House.

The Supreme Court Settled This in 1990
Governors challenged federalization authority directly and lost. In Perpich v. Department of Defense, several governors argued that the federal government could not send their Guard units on training missions abroad without gubernatorial consent. The Supreme Court ruled unanimously against them, holding that Congress may authorize the National Guard to be ordered to active federal duty for training outside the United States without either the consent of a state governor or a declaration of national emergency.9Oyez. Perpich v. Department of Defense
The Court’s reasoning rested on the dual-enlistment system in place since 1933. Every Guard member simultaneously belongs to a state militia and a federal reserve component. When the President activates them for federal duty, their state militia status is effectively suspended, and the governor has no legal mechanism to block it because the federal enlistment operates independently. Justice Stevens, writing for the unanimous Court, held that Article I’s plain language “establishes that Congress may authorize members of the National Guard of the United States to be ordered to active federal duty” without gubernatorial approval.10Library of Congress. Perpich v. Department of Defense, 496 U.S. 334 (1990)
A governor who refuses a federalization order today is making a political statement, not asserting a legally defensible right.
What Governors Can and Cannot Do
History bears the settled law out. In 1957, Arkansas Governor Orval Faubus deployed his state’s National Guard to block nine Black students from entering Little Rock Central High School in defiance of a federal desegregation order. President Eisenhower responded with Executive Order 10730, federalizing the entire Arkansas National Guard and deploying the 101st Airborne Division.11National Archives. Executive Order 10730 – Desegregation of Central High School (1957) The same Guard members who had been blocking the school entrance were, the next day, under presidential command. Faubus’s opposition became legally irrelevant the moment the order took effect.
After Hurricane Katrina in 2005, the Bush administration pressed Louisiana Governor Kathleen Blanco to sign a memorandum federalizing her state’s Guard. She refused, and the President chose not to force the issue. The Guard operated under state command throughout the response. That episode is often cited as a governor “blocking” federalization, but it wasn’t: the President had the authority and declined to use it. Political cost, not legal limit, drove the outcome.
The one area where governors have won in court is the flip side of the question. In Abbott v. Biden (2023), the Fifth Circuit sided with Texas Governor Greg Abbott, holding that the Department of Defense could not punish non-federalized Guard members who refused the military’s COVID-19 vaccine mandate. The court held that the Constitution’s text, history, and tradition “foreclose the President’s efforts to impose such punishments” on Guard members who had not been called into federal service.12Justia Law. Abbott v. Biden, No. 22-40399 (5th Cir. 2023)
That ruling actually reinforces the federalization framework rather than undermining it. Federal authority over Guard members depends on actually calling them into federal service. Without that call-up, the President cannot reach into state Guard ranks to discipline anyone. With it, the legal picture flips completely.
What Happens to a Guard Member Who Refuses
A governor’s political objections don’t shield individual Guard members from their own legal obligations. Once a federal call-up order is issued, Guard members are required to report, and from the moment they are required to respond they fall under the Uniform Code of Military Justice.3Office of the Law Revision Counsel. 10 USC 12405 – National Guard in Federal Service: Status
Under UCMJ Article 90, a service member who willfully disobeys a lawful command of a superior commissioned officer faces court-martial. In peacetime, punishment is at the court-martial’s discretion and can include confinement, forfeiture of pay, and reduction in rank. In time of war, the maximum penalty is death.13Office of the Law Revision Counsel. 10 USC 890 Art. 90 – Assaulting or Willfully Disobeying Superior Commissioned Officer
The most damaging outcome for most people is a dishonorable discharge, which only a general court-martial can impose. Federal law bars anyone discharged by sentence of a general court-martial from receiving VA benefits, including disability compensation, pension, healthcare, and education benefits.14Office of the Law Revision Counsel. 38 USC 5303 – Certain Bars to Benefits A dishonorable discharge also follows a person into civilian life, appearing on background checks and disqualifying them from many jobs.
For a Guard member weighing what to do when a federalization order arrives during a public standoff between their governor and the President, the legal picture is not ambiguous. Whatever the governor says publicly, the obligation runs to the federal chain of command once the activation order takes effect, and the penalties for treating that obligation as optional are severe and lasting.
