The Insurrection Act, established in 1807, permits the U.S. President to deploy federal military forces domestically to suppress rebellion and enforce civilian law. Invoking this Act temporarily suspends the prohibition against federal troops conducting civilian law enforcement. The President can activate the Act when federal law cannot be enforced through normal judicial proceedings due to unlawful obstructions or rebellions. The Act has been invoked approximately 30 times since 1808, notably during the 1950s and 60s for school integration and the 1992 Los Angeles riots.
Martial law involves the imposition of military control over civilian functions. It is distinct from the Insurrection Act, which uses the military to enforce civilian law. The U.S. Supreme Court has stated that martial law lacks a precise definition and is not explicitly defined in the Constitution or by Congress. Historically, martial law has been declared in limited circumstances, such as during the Civil War and after the 1941 attack on Pearl Harbor.
"Plenary authority" refers to broad, often extensive power. Within the context of federal law, the President has certain powers, such as calling National Guard units into federal service when regular forces are insufficient. However, this authority is not limitless due to the system of checks and balances among the legislative, executive, and judicial branches. Title 10 of the U.S. Code outlines the constraints on military and presidential powers.
President to deploy federal military forces domestically to suppress rebellion and enforce civilian law.
The Posse Comitatus Act of 1878 generally prohibits the use of the military for domestic law enforcement, except under the Insurrection Act. The Act restricts the direct active use of military personnel for civilian law enforcement purposes. The National Guard, when under state authority, is not subject to these restrictions, but the Act applies when it is federalised.
The National Guard is a state-based military force with federal responsibilities. It responds to domestic emergencies and supports military operations overseas. Comprising over 430,000 members across all states and U.S. territories, the Guard is typically mobilised by governors but can be federalised by the President under certain conditions. The National Guard has been deployed in various instances, including the 2020 protests and the 1992 Los Angeles riots.
