Martial Law: Can States Take This Extreme Measure?

The concept of martial law is not well-defined and has been imposed at least 68 times in limited, usually local areas of the United States. In the US, martial law occurs when the military assumes temporary control over various civilian authorities, usually in times of war, natural disaster, or civic dispute. While the US President and Congress have the power to impose martial law, the law surrounding the concept is complicated and unsettled. The US Constitution does not define martial law and does not specify who can declare it. The Supreme Court has never clearly stated whether the federal government has the power to declare martial law, and if so, whether the president could unilaterally declare it or whether it would require congressional authorization. State officials may declare martial law, but their actions under the declaration must abide by the US Constitution.

Who can declare it?

The law surrounding the concept of martial law is complicated and unsettled. The US Constitution does not define martial law, nor does it specify who can declare it. In the United States, martial law usually refers to a power that, in an emergency, allows the military to take the place of the civilian government and exercise jurisdiction over civilians in a particular area.

The US President does not have the power to impose martial law. The Posse Comitatus Act, enacted in 1878, forbids US military involvement in domestic law enforcement without congressional approval. The legislation does not include authorization for the president to impose martial law, and the Supreme Court has never explicitly stated that the federal government has the power to declare it. However, the 1952 ruling in Youngstown Sheet & Tube Company v. Sawyer could be used by a court to determine whether a president’s martial law declaration exceeded their authority.

The US Congress has the authority to regulate the domestic deployment of the military and has enacted comprehensive legislation in that area. Congress could, therefore, provide authorization for the president to impose martial law. However, it has not done so, and the Supreme Court has not conclusively decided that the federal government is constitutionally empowered to declare martial law.

State officials can declare martial law, and in nearly every state, the governor has the power to impose it within the borders of the state. States have declared martial law far more frequently than the federal government.

What does it mean?

The meaning of martial law is a complicated and unsettled area of law. There is no established definition of martial law, and the Supreme Court has never explicitly stated whether the federal government has the power to declare it. The Constitution does not define martial law, and it does not specify who can declare it.

Martial law usually refers to a power that, in an emergency, allows the military to take the place of the civilian government and exercise jurisdiction over civilians in a particular area. It can be imposed when civil rule fails, and military authority temporarily replaces it in a time of crisis. It has been declared in times of war, natural disaster, and civic dispute. In the United States, martial law has been imposed at least 68 times, mostly by states rather than the federal government.

In the US, both the US President and the US Congress have the power, within certain constraints, to impose martial law since both can be in charge of the militia. However, the Posse Comitatus Act of 1878 forbids US military involvement in domestic law enforcement without congressional approval. The Insurrection Act of 1807 allows the president to deploy the military to put down rebellions and help local law enforcement. The scope and limits of martial law remain unclear until Congress and state legislatures enact new laws to better define them.

The Supreme Court has held that individual states have the power to declare martial law, and such a declaration is valid if authorized by the constitution or laws of the state. State officials may also declare martial law, but their actions must abide by the US Constitution.

What are the limits?

The exact scope and limits of martial law in the United States remain unclear. While the US Constitution does not define martial law and does not specify who can declare it, it does state that "The Privilege of the Writ of Habeas Corpus shall not be suspended, unless when in Cases of Rebellion or Invasion the public Safety may require it." This means that even under martial law, the government cannot suspend or violate constitutional rights.

Martial law has been imposed at least 68 times in limited, usually local areas of the United States. It has been declared twice for war or invasion, seven times for domestic war or insurrection, eleven times for riot or civil unrest, 29 times for labour dispute, four times for natural disaster, and fifteen times for other reasons.

While the Supreme Court has held that states can declare martial law, it has never specifically held that the president can. The Posse Comitatus Act, passed by Congress in 1878, prevents the US military from participating in civilian law enforcement activities without congressional approval. The Insurrection Act of 1807 allows the president to deploy military forces to put down rebellions within the United States and deploy the military to help local law enforcement deal with domestic violence.

The concept of martial law is further complicated by the fact that there is no established definition. Different people have used the term to describe a wide variety of actions, practices, or roles for the military. As a result, the exact scope and limits of martial law remain unclear until Congress and state legislatures enact new laws that better define them.

What's the history?

The history of martial law in the United States is a complex and, at times, confusing topic. While there is no universal definition, it often refers to the use of the military for law enforcement, with the military replacing the civilian government and exercising jurisdiction over civilians in a particular area. The term "martial law" has been used to describe a wide variety of actions, practices, or roles for the military, and its exact scope and limits remain unclear.

The first declaration of martial law in the US was in New Orleans by General Andrew Jackson during the War of 1812. It was declared in response to the Battle of New Orleans and lasted from December 12, 1814, to March 13, 1815. This decision was unpopular, and Jackson was fined $1,000 for having a critical reporter arrested. Martial law was also declared during the Illinois Mormon War, when Joseph Smith, the founder of Mormonism, was charged with attempting to overthrow the government. Smith declared martial law in Nauvoo, calling on the Nauvoo Legion, a city militia of about 5,000 men, to protect the city from outside violence.

Martial law has been declared more than 60 times in US history, mostly by state and local officials. Notable instances include the Great Chicago Fire of 1871, the 1906 San Francisco earthquake, the Omaha race riot of 1919, the 1920 Lexington riots, the 1934 West Coast waterfront strike, and during the Civil Rights Movement in response to the Cambridge riot of 1963. Hawaii was under martial law from 1941 to 1944 following the Japanese attack on Pearl Harbor.

The legal basis for martial law is found in the Constitution, which gives Congress the authority to regulate the domestic deployment of the military. However, the specific laws governing martial law are complicated and unsettled. The Supreme Court has never clearly stated whether the federal government or the president has the power to declare it unilaterally. While Congress might be able to authorize a presidential declaration, this has not been conclusively decided. State officials do have the power to declare martial law, but their actions must abide by the US Constitution and are subject to review in federal court.

Can it be challenged?

The legality of martial law is a complex and unresolved issue. The US Constitution does not define martial law or specify who can declare it. While the US President is the Commander-in-Chief of the armed forces, the Constitution does not explicitly authorise the President to declare martial law. The Supreme Court has also never explicitly stated whether the federal government or the President can declare martial law.

However, the Supreme Court has held that individual states have the power to declare martial law, and such a declaration is valid if authorised by the Constitution or state laws. This power is more clearly established for states, but there are still significant limits. For example, the Posse Comitatus Act of 1878 forbids US military involvement in domestic law enforcement without congressional approval. Additionally, martial law declarations are subject to judicial review, and individuals detained under martial law can petition for a writ of habeas corpus.

The scope and limits of martial law remain unclear, and Congress and state legislatures have been urged to enact new laws to better define them. The absence of clear legislation leaves the concept open to competing interpretations and potential abuse of power.

While the President may not have the authority to declare martial law, they can still deploy the military domestically in certain situations. The Insurrection Act allows the President to deploy the military to address rebellions and support local law enforcement in dealing with civil violence.

In summary, the legality of martial law is a grey area, and while states have greater clarity on their power to declare it, there are limits and checks in place. The President's ability to deploy the military domestically, even without declaring martial law, is also a concern.
