Martial law is a state of emergency where civilian rule is replaced by military authority. It is usually invoked in times of war, rebellion, or natural disaster. While the power to declare martial law varies by country, in the United States, both the President and Congress have the power to impose martial law, and in nearly every state, the governor can also impose it within their state's borders. However, the President's authority to declare martial law is disputed, with some arguing that Congress must authorize it. Throughout history, martial law has been declared over 60 times in the United States and has been used in various countries like India, Indonesia, Iran, Syria, Taiwan, Ukraine, and the United Kingdom.

What You'll Learn

US President and Congress
In the United States, martial law refers to instances when a region, state, city, or the entire country is placed under the temporary control of a military body. This usually occurs when civilian authority over an area has ceased to function, such as during a war, rebellion, insurrection, or natural disaster.
The US Constitution does not define martial law, nor does it specify who can declare it. However, it is clear that both the US President and the US Congress have the power to impose martial law, within certain constraints. While the President has the authority to use troops domestically to assist in civilian law enforcement activities, the Posse Comitatus Act of 1878 forbids US military involvement in domestic law enforcement without congressional approval. This Act strengthens the separation of powers between Congress and the President. Additionally, Congress has passed a wide variety of laws that regulate when and where the military may be used domestically, further limiting the President's ability to act without congressional authorization.
Despite these constraints, several US Presidents throughout history have imposed or approved declarations of martial law. This ambiguity and the breadth of the President's statutory authority highlight the need for Congress to pass clearer legislation defining the scope and limits of presidential powers regarding martial law.
While the exact scope and limits of martial law are unclear due to sparse and confusing legal precedents, Congress might be able to authorize a presidential declaration of martial law. However, this has not been conclusively decided, and the Supreme Court has never specifically held that the President can declare martial law.

US State Governors
In the United States, martial law refers to instances when a region, state, city, or the entire country is placed under the temporary control of a military body. This occurs when civilian authority has ceased to function, is completely absent, or has become ineffective.
While the US Constitution does not specify who can declare martial law, state governors have the power to impose it within their state borders. Throughout history, state governors have imposed or approved declarations of martial law. For example, in May 1961, Governor Patterson of Alabama declared martial law in response to peaceful civil rights activists challenging racial segregation in the South. In June 1970, martial law was imposed in Isla Vista, California, following student protests against the Vietnam War.
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. While the president has the authority to use troops domestically to assist in civilian law enforcement, it is unclear whether they can legally declare martial law without congressional authorization. Congress has passed various laws, such as the Posse Comitatus Act and the Insurrection Act, that regulate the domestic use of the military and limit the president's ability to declare martial law.

Indian Supreme Court
The Indian Constitution does not explicitly define the term "martial law". However, Article 34 of the Constitution of India, 1950, provides for indemnifying individuals for acts performed to maintain order during martial law in areas where it is declared. This implies that martial law can be invoked in India. Nevertheless, it does not outline a clear process or grounds for declaring martial law.
The Indian Supreme Court has played a significant role in interpreting and upholding certain rights related to martial law. In the case of Puttaswamy vs. Union of India, the Supreme Court affirmed that specific rights, such as life and liberty, are inherent and cannot be infringed upon by the state. Additionally, the Court recognised the inherent right of courts to issue writs.
The Supreme Court has also provided clarity on the suspension of the writ of habeas corpus during martial law. In the case of A.D.M. Jabalpur vs. S. Shukla (1976), the Court observed that martial law does not automatically result in the suspension of habeas corpus. Instead, it emphasised the restricted nature of martial law, indicating that it involves the military taking over specific situations rather than a blanket suspension of civil rights.
While India has never officially declared martial law since independence, it has relied on constitutional emergency provisions outlined in Articles 352 (national emergency), 356 (state emergency), and 360 (financial emergency) to manage extraordinary situations. These provisions have faced criticism for their potential overreach, particularly during the Emergency of 1975-1977.
In summary, while the Indian Supreme Court does not have the explicit power to declare martial law, it plays a crucial role in interpreting and safeguarding citizens' rights during periods of emergency and potential martial law scenarios.

British Raj
During the British Raj, martial law was imposed in India by the British Empire. The British Empire commonly resorted to martial law when facing insurgencies in its colonies.
Martial law was declared in the Defense of India Act, 1915, and the Defense of India Act, 1939. It was also declared in most of Punjab during 1919 in response to the Amritsar Massacre, which was caused by the controversial Rowlatt Act. The Government of India believed that the disturbances in Punjab were not sporadic riots but organised uprisings with an anti-government and anti-British bias. The simultaneous cutting of railway and telegraph lines, deliberate destruction of government property, and attacks on public buildings pointed to a common purpose. The declaration of martial law in Punjab suspended the functions of the ordinary Criminal Courts of Judicature, and the Governor-General was empowered to direct the immediate trial by courts-martial of persons owing allegiance to the British Government.
Martial law was also imposed in Ireland by the British authorities during the Easter Rising in 1916, the Irish War of Independence, and the Irish Civil War. Lord Wimborne, the Lord Lieutenant of Ireland, declared martial law to maintain order in the streets of Dublin. This was later extended to the whole country with the consent of the United Kingdom government.
Martial law refers to the temporary imposition of direct military control over civilian administration during emergencies, such as war, rebellion, or natural disasters. It involves the suspension of civilian laws and rights, with the military taking over functions such as policing, judicial processes, and governance. While it can restore order in chaotic situations, martial law risks violating fundamental rights and eroding democratic norms.

Ukrainian President
The Ukrainian President is the head of state and is responsible for conducting strategic oversight of the armed forces during martial law. The President can issue a decree to impose martial law, which must be approved by the Verkhovna Rada (Ukrainian legislature).
On February 24, 2022, Ukrainian President Volodymyr Zelensky issued Decree No. 64/2022 on the Introduction of Martial Law in the entire territory of Ukraine. The Verkhovna Rada approved the decree, allowing the imposition of martial law for an initial period of 30 days. This decision was made in response to the military aggression of the Russian Federation and was based on a proposal by the National Security and Defense Council. The decree stated that Ukraine's defense, public safety, and state interests must be ensured, as prescribed by the Law on the Legal Regime of Martial Law.
The Ukrainian President has the authority to extend martial law as needed. For example, on November 9, 2023, President Zelensky signed laws extending martial law and general mobilization by 90 days, following Russian missile strikes on Ukrainian civilian targets. The extension was passed by the Verkhovna Rada on November 8 and demonstrated the ongoing need for heightened security measures.
During martial law in Ukraine, certain constitutional rights and freedoms may be temporarily restricted. This includes restrictions on freedom of movement, stricter ID checks, and the prohibition of male citizens aged 18-60 from leaving their permanent residency without approval. The government also gains the right to control the media, ban the sale of weapons and alcoholic beverages, regulate medicine production, and seize radioactive materials.
The Ukrainian President plays a crucial role in activating and overseeing martial law, ensuring the country's defense and the protection of its citizens' rights during extraordinary circumstances.
