The concept of martial law and its implementation have been a topic of debate and discussion throughout American history. While the Constitution does not explicitly define or grant the president the power to declare martial law, several presidents and state governors have imposed or approved it. The Supreme Court has also never specifically ruled on the president's authority to declare it. The power to declare martial law is a complex and contentious issue, with scholars and legal experts offering differing interpretations of the Constitution's war powers. The lack of a clear definition of martial law and the sparse legal precedent make it a challenging area of law to navigate.

The US Constitution and martial law
The US Constitution does not define martial law, nor does it specify who can declare it. However, the document does divide war powers between Congress and the president, requiring the commander-in-chief to be a civilian. This suggests that the president does not have “conclusive and preclusive" authority over the domestic use of the military and, therefore, cannot declare martial law unilaterally.
Throughout history, the federal and state governments have declared martial law over 60 times, with the president imposing or approving it on several occasions. For example, in 1863, President Lincoln imposed Congressionally authorized martial law on Kentucky, Maryland, and Missouri, suspending habeas corpus and civil rights. The Supreme Court later ruled that Lincoln's imposition of martial law was unconstitutional in areas where local courts were still operational.
While the Supreme Court has never explicitly ruled that the president can declare martial law, modern interpretation allows the president and state officials to declare "degrees of martial law in specific circumstances." Some scholars argue that the president has the executive power to do so, while others believe congressional authorization is required. Thus, Congress may be the only governmental branch that can legally declare martial law, with the president acting according to its authorization.
State officials have also declared martial law in response to violent civil unrest, natural disasters, and, more frequently, to break labor strikes. These declarations must abide by the US Constitution and are subject to review in federal court.
In summary, while the US Constitution does not explicitly address martial law, it implies that the president does not have the sole authority to declare it. The power to impose martial law lies with Congress, and state officials can also declare it under certain circumstances.

Supreme Court rulings on martial law
In the United States, the Constitution does not define martial law and does not specify who can declare it. While the Supreme Court has held that states can declare martial law, it has never explicitly ruled that the president can. Therefore, it is unclear whether the president can legally declare martial law. However, throughout history, several presidents have imposed or approved declarations of martial law.
The Supreme Court's decision in Luther v. Borden (1849) established that during wartime, "supreme political authority" allows for the valid and constitutional use of martial law. Additionally, scholars argue that the Constitution's enumerated war powers grant both Congress and the president the authority to declare martial law.
In the Philippines, the Supreme Court upheld the constitutionality of President Rodrigo Duterte's declaration of martial law in Mindanao in 2017. The Court voted 11-3-1 to dismiss the petitions against martial law, with the majority agreeing that the proclamation was legal and necessary to address security threats. However, critics warned that Duterte might abuse his power and there were concerns about the lack of a factual basis for the declaration.
In summary, while the Supreme Court has acknowledged the validity of martial law under certain conditions, it has not explicitly authorized the president to declare it. The power to declare martial law remains ambiguous, with some scholars and legal interpretations suggesting congressional authorization is required for a presidential declaration.

Presidential power to declare martial law
The Constitution of the United States does not define martial law and does not specify who can declare it. The Supreme Court has never explicitly ruled that the president can declare martial law, and neither the Constitution nor federal law explicitly authorises the president to do so. However, several presidents throughout history have imposed or approved declarations of martial law.
Some scholars argue that the president has the executive power to declare martial law. They base this argument on the Constitution's enumerated war powers, which give both Congress and the president some control over America's military forces. Additionally, during wartime, "supreme political authority" may allow for the valid and constitutional use of martial law.
However, others disagree and believe that the president requires congressional authorisation to impose martial law in a civilian area. According to this view, Congress may be the only governmental branch that can legally declare martial law, and the president can only act according to its authorisation. Furthermore, the Posse Comitatus Act and other federal laws restrict the president's ability to deploy the military for civilian law enforcement, further limiting the president's ability to declare martial law unilaterally.
While the legal questions surrounding martial law remain complex and unsettled, it is clear that the president's power to declare martial law, if any, is subject to significant constraints and is not an unlimited authority.

State governor's authority during martial law
While the US Constitution does not define martial law, and it is unclear whether the president can declare it, state governors have historically been able to impose or approve declarations of martial law.
According to national security law scholar Joseph Nunn, martial law is a "dramatic departure from normal practice in the United States". Federal laws usually prevent the military from acting within the country. However, the president can call the military into action to help local governments after a natural disaster. 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, giving the military commander virtually unlimited authority to govern an area.
Throughout history, martial law has been imposed at least 68 times in limited, usually local areas of the US. 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.
State governors can declare martial law whenever it is authorized by state law, and federal courts are likely to defer to a state governor’s decision that doing so was necessary. However, the exact scope and limits of martial law remain unclear until Congress and state legislatures enact new laws that better define them. The Supreme Court precedent is too old, sparse, and inconsistent to provide any certainty around martial law.
In summary, while the president's authority to declare martial law is unclear, state governors have historically had the power to impose or approve declarations of martial law, and their authority to do so is backed by state law and federal courts. However, the exact scope and limits of their authority are unclear and subject to interpretation.

Martial law and civilian government
The concept of martial law and who can declare it is a complicated and unsettled area of law. The US Constitution does not define martial law, nor does it specify who can declare it. The Supreme Court has never explicitly ruled that the president can declare martial law, and legal scholars disagree on whether the president has the power to do so. Some believe the president has the executive power to declare it, while others argue that congressional authorization is required.
Martial law 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. When martial law is declared, local laws, civil authority, and sometimes local judiciaries are suspended, and a military commander assumes virtually unlimited authority to govern the area.
While the president is the Commander-in-Chief of the Army, Navy, and Militia of the United States, the Constitution does not grant the president conclusive and preclusive authority over the domestic use of the military. Congress has placed clear restrictions on the president's ability to use the military domestically, and a unilateral declaration of martial law by the president would violate these rules. However, Congress has granted the president considerable authority to use troops domestically in ways short of martial law, such as through the Insurrection Act.
State officials, including governors and legislatures, have the power to declare martial law, and they have done so throughout history. However, their actions under a declaration of martial law must abide by the US Constitution and are subject to review in federal court.
