Congress' Power To Deny Martial Law: Explained

There is much debate over whether the president has the power to declare martial law. Some scholars believe the president has the executive power to do so, while others believe the president needs congressional authorization to impose martial law in a civilian area. Congress has several checks on the executive branch, including the impeachment power, and has the legislative power to declare war. While the Constitution does not define martial law, its use throughout history has defined its application and limits.

Congress may be the only governmental branch that can legally declare martial law

Articles I and II of the Constitution give each branch some control over America's military forces. Congress has several checks on the executive branch, including the impeachment power. Congress has also passed a multitude of laws related to domestic military deployment, giving the president considerable authority to use troops domestically in ways short of martial law.

State officials do have the power to declare martial law, but their actions under the declaration must abide by the U.S. Constitution and are subject to review in federal court.

The president does not have the power to declare martial law

The Constitution does not grant the president “conclusive and preclusive” power over the issue of domestic military deployment. Instead, it gives most of the relevant authority to Congress. Therefore, under Youngstown, the president would not have the constitutional authority to override the restrictions Congress has put in place, and a unilateral declaration of martial law would not survive a legal challenge. There are no existing federal statutes that authorize the president to declare martial law.

The Posse Comitatus Act, enacted by Congress in 1878, prevents the United States military "from participating in civilian law enforcement activities." Its enactment strengthened the separation of powers between Congress and the president.

While the president can call the military into action to help local governments after a natural disaster, like a hurricane, its help is usually limited. When the federal or state governments declare martial law, they suspend all local laws, civil authority, and, sometimes, local judiciaries. In their place, the commanding officer substitutes temporary laws and military tribunals.
