These terms defy simple definitions after decades of interpretation by the courts.<\/p>\n<p>We explain what they are:<\/p>\n<h2 id=\"what-is-the-insurrection-act\">What is the Insurrection Act?<\/h2>\n<p>This 1807 law allows the US president to deploy federal military personnel domestically to suppress rebellion and enforce civilian law.<\/p>\n<p>Invoking the Insurrection Act temporarily suspends another US law that forbids federal troops from conducting civilian law enforcement. A president can invoke the law after determining that \u201cunlawful obstructions, combinations, or assemblages, or rebellion\u201d against the federal government make it \u201cimpracticable to enforce\u201d US law \u201cby the ordinary course of judicial proceedings\u201d, the law says. In those cases, the Insurrection Act would allow the president to direct federal troops to enforce US laws or stop a rebellion.<\/p>\n<p>The law is broadly written and does not define terms such as \u201cinsurrection\u201d or \u201crebellion\u201d. The US Supreme Court ruled in 1827 that the president has exclusive power to decide whether a situation represents an acceptable reason to invoke the law.<\/p>\n<p>Chris Edelson, an American University assistant professor of government, previously said the law provides \u201climited authority\u201d for the president to use the military to respond to \u201cgenuine emergencies \u2013 a breakdown in regular operational law when things are really falling apart\u201d.<\/p>\n<p>The Insurrection Act has been formally invoked about 30 times in the US since 1808, including when southern governors refused to integrate schools in the 1950s and 60s and during the 1992 Los Angeles riots, after four white police officers were acquitted in the roadside beating of Rodney King, a Black man.<\/p>\n<h2 id=\"what-is-martial-law\">What is martial law?<\/h2>\n<p>People sometimes conflate martial law with the Insurrection Act. Martial law\u00a0typically refers\u00a0to imposing military law on civilians, while the Insurrection Act uses the military to impose civilian law. Martial law is more stringent and has fewer protections than civilian law, experts said.<\/p>\n<p>The Supreme Court wrote in a 1946 ruling that the term martial law \u201ccarries no precise meaning\u201d and that it was not defined in the Constitution or in an act of Congress. Legal experts say, because of this, it is not clear whether the US president has a legal path to declaring martial law in the way that it is commonly understood.<\/p>\n<p>Still, it has been declared in the past. The US imposed\u00a0martial law\u00a0in Hawaii\u00a0after the 1941 Japanese attack on Pearl Harbor, and President Abraham Lincoln\u00a0declared\u00a0martial law in certain parts of the country during the\u00a0Civil War.<\/p>\n<p>The Supreme Court held in 1866 that martial law could be imposed only if civilian courts were not functioning.<\/p>\n<p>The court \u201cmore or less found that martial law could only be declared in an active war zone\u201d, said Chris Mirasola, University of Houston Law Center assistant professor. \u201cThe circumstances within which presidents have invoked martial law and that the Supreme Court has understood martial law are incredibly narrow. It would require an active hostility on US territory that prevents civilian legal proceedings from occurring.\u201d<\/p>\n<p>Trump, who has shown a willingness to challenge constitutional precedent, has continued to muse about using military powers against civilians. Trump told top US military commanders on September 30 that the military could be used against the \u201cenemy within\u201d and suggested that some cities could be used as military \u201ctraining grounds\u201d.<\/p>\n<h2 id=\"what-is-plenary-authority\">What is plenary authority?<\/h2>\n<p>\u201cPlenary authority\u201d is defined by the Legal Information Institute at Cornell Law School as \u201cpower that is wide-ranging, broadly construed, and often limitless for all practical purposes\u201d.<\/p>\n<p>The term made headlines when White House Deputy Chief of Staff Stephen Miller started to say that Trump has \u201cplenary authority\u201d to deploy National Guard troops to US cities in an October 6 CNN interview. Miller abruptly stopped talking, and CNN said the disruption was due to a technical glitch. But social media users said Miller froze because he mentioned plenary authority.<\/p>\n<p>When the show returned, Miller finished his answer, saying he was \u201cmaking the point that under federal law, Title 10 of the US Code, the president has the authority anytime he believes federal resources are insufficient to federalise the National Guard to carry out a mission necessary for public safety\u201d.<\/p>\n<p>Although the president has broad powers under the Constitution, like issuing pardons for federal crimes, he does not have limitless power. The US government is divided into three branches \u2013 legislative, executive and judicial \u2013 in order to have checks and balances.<\/p>\n<p>Title 10 of the US Code outlines the role of the country\u2019s armed forces and constrains what the military is allowed to do and what orders the president can lawfully issue.<\/p>\n<p>It does not include terms like \u201cplenary authority\u201d or \u201cplenary power\u201d. Instead, it says when the president \u201cis unable with the regular forces to execute the laws\u201d and the US faces a foreign invasion, a rebellion, or danger of rebellion, the president \u201cmay call into Federal service members and units of the National Guard of any state\u201d.<\/p>\n<p>A judge in Oregon has twice blocked the Trump administration from deploying National Guard troops to Portland; a federal appeals court also blocked the administration from deploying the guard to Chicago, saying troops can remain federalised for now but cannot be deployed.<\/p>\n<p>Trump officials say the guard is needed to protect Immigration and Customs Enforcement (ICE) officers and federal facilities. Trump previously cited section 12406 of Title 10 when he called for National Guard troops to be sent to Los Angeles during immigration protests in June. A federal judge ruled in <a href=\"http:\/\/www.aljazeera.com\/news\/2025\/9\/2\/us-judge-declares-trumps-military-deployment-to-los-angeles-illegal\">September<\/a> that the deployment violated the law. The administration is\u00a0appealing.<\/p>\n<h2 id=\"what-is-the-posse-comitatus-act\">What is the Posse Comitatus Act?<\/h2>\n<p>The\u00a0Posse Comitatus Act, passed in\u00a01878, generally prevents the use of the military as a domestic police force on US soil, with exceptions for the Insurrection Act.<\/p>\n<p>The phrase \u201cposse comitatus\u201d refers to a group of people called upon by a county sheriff to maintain peace and suppress lawlessness. Think of Western movie depictions of posses of townspeople gathering to catch fugitives. \u201cThe Posse Comitatus Act is so named because one of the things it prohibits is using soldiers rather than civilians as a posse comitatus,\u201d the Brennan Center for Justice, a nonprofit policy institute, wrote in 2021.<\/p>\n<p>As the Posse Comitatus Act has been interpreted by the courts, civilian law enforcement officials cannot make \u201cdirect active use\u201d of military personnel, including using federal military forces, over their citizens to \u201cregulatory, prescriptive, or compulsory authority,\u201d according to the Congressional Research Service.<\/p>\n<p>The Posse Comitatus Act does not apply to the National Guard when it is under state authority and the command of a governor; the law\u2019s restrictions apply when the National Guard is federalised by the president. This means the National Guard generally cannot conduct arrests, searches or seizures unless there is an exception, such as the Insurrection Act.<\/p>\n<p>The only National Guard exception is the District of Columbia\u2019s, which is\u00a0solely\u00a0under federal control.<\/p>\n<h2 id=\"what-is-the-national-guard\">What is the National Guard?<\/h2>\n<p>The National Guard is a state-based military force with certain federal responsibilities. It often responds to domestic emergencies, such as natural disasters and civil unrest, and can support US military operations overseas.<\/p>\n<p>More than 430,000 National Guard members serve in units in all 50 states, the District of Columbia, and the US territories of Guam, Puerto Rico and the US Virgin Islands.<\/p>\n<p>The National Guard typically operates as a part-time reserve force that can be mobilised for active duty by governors. The guard also helps train foreign allies in more than 100 countries under the State Partnership Program.<\/p>\n<p>A president, in some cases, can federalise and take control of a state\u2019s National Guard over the objection of governors for domestic missions and to serve in wars overseas, but it rarely happens without governors\u2019 consent. When the National Guard is federalised, its troops are subject to the same restrictions as federal troops.<\/p>\n<p>The National Guard has been federally mobilised in the US <a href=\"http:\/\/www.aljazeera.com\/news\/2025\/8\/25\/when-and-why-has-the-national-guard-been-deployed-in-the-us-before\">several times<\/a>, including in response to the <a href=\"http:\/\/www.aljazeera.com\/news\/2020\/6\/1\/george-floyd-mapping-us-national-guard-deployments\">2020 protests<\/a> over the murder of George Floyd; the 1992 Los Angeles riots; and civil unrest following the 1968 assassination of Martin Luther King Jr.<\/p>\n<p>The Ohio National Guard\u2019s 1970 deployment to antiwar protests at Kent State University resulted in troops shooting students, killing four people and injuring nine others.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>When asked whether United States President Donald Trump would invoke the Insurrection Act, Vice President JD Vance said this week that Trump is \u201clooking at all his options\u201d.
