Martial Law: Mass Deportations And Human Rights

Former US President Donald Trump has long threatened to carry out the largest deportation operation in American history, and has invoked the Alien Enemies Act, a 1798 wartime law, to deport people to El Salvador. While the Act does not authorize military deployment, Trump has indicated that he will also invoke the Insurrection Act, which is a statutory exception to the Posse Comitatus Act, to deploy the military for mass deportations. The Posse Comitatus Act prohibits federal armed forces from executing laws or participating in civilian law enforcement activities. The ACLU and the New York Civil Liberties Union have challenged Trump's use of the Alien Enemies Act, and a federal court in New York has granted an injunction blocking removals under the Act for people within its judicial district.

The Alien Enemies Act

The Act permits the president to target immigrants without a hearing and based solely on their country of birth or citizenship. It has been used to detain and deport citizens of an enemy nation, and in the case of World Wars I and II, it was used to target German, Austro-Hungarian, Japanese, and Italian immigrants based on their ancestry.

The Act does not authorize military deployment or participation in law enforcement. However, when combined with the Insurrection Act or other authorities, it could permit the militarized deportation of immigrants lawfully in the country.

In 2024, President Trump invoked the Alien Enemies Act to carry out mass deportations, particularly targeting Latino immigrants who were undocumented or involved in criminal drug activity. Trump's use of the Act was blocked by a federal court in New York, which ruled that the presidential proclamation exceeded the scope of the Act as there was no "war," "invasion," or "predatory incursion."

The invocation of the Act by Trump was seen as a dangerous attempt to consolidate power and claim unilateral authority to decide who is an "enemy." It raised concerns about the potential abuse of emergency powers to unfairly target people based on their nationality, ancestry, or political ideology.

The Insurrection Act

The Act is a statutory exception to the Posse Comitatus Act, which generally prohibits the use of the military for domestic law enforcement. The Insurrection Act can be invoked when there is civil unrest or rebellion that has overwhelmed law enforcement. The Act does not define key terms such as "insurrection", "rebellion", or "domestic violence", leaving the interpretation of these terms to the president's discretion.

The use of the Insurrection Act for mass deportations is controversial and may be subject to legal challenges. Critics argue that the Act is not meant to be used for immigration enforcement and that it could lead to violations of civil liberties. The potential for abuse of power is a significant concern, and there have been calls for the Act to be overhauled or repealed.

The Posse Comitatus Act

While the Posse Comitatus Act generally prohibits the use of the military for domestic law enforcement, there are statutory exceptions. The most notable exception is the Insurrection Act, which allows the president to use the military to suppress rebellions, enforce federal laws, or protect civil rights when a state government is unable or unwilling to do so. Another exception is the Enforcement Acts, which President Dwight D. Eisenhower used to send federal troops to Little Rock, Arkansas, during the 1957 school desegregation crisis. Additionally, the Coast Guard, while part of the armed forces, is not bound by the Posse Comitatus Act as it has explicit statutory authority to perform law enforcement duties.

The National Guard is rarely covered by the Posse Comitatus Act, as they typically report to their state or territory's governor and can participate in law enforcement if allowed by state law. However, when National Guard personnel are federalized, they become subject to the Act until they return to state control. An example of this exception occurred during the 2020 George Floyd protests in Washington, D.C., when National Guard troops were called in to suppress protests without invoking the Insurrection Act.

Expansion of the expedited removal program

The Trump Administration expanded the scope of expedited removal in July 2019 to include aliens anywhere in the US for less than two years. This was reinstated in 2025, at the beginning of Trump's second term. The expansion was challenged in court by the ACLU and reversed by the Biden Administration in March 2023.

The expansion of the expedited removal program puts undocumented community members at greater risk of being put in a rapid deportation process without the right to appear in front of an immigration judge or fight their case. This includes any deportable alien encountered anywhere in the country who has been present in the US for less than two years.

The program primarily targets non-citizens who arrive at designated ports of entry or are apprehended within 100 miles of the border within 14 days of arrival. With the expansion, non-citizens across the US who were not admitted by immigration authorities and have been in the country for up to two years now face the risk of fast-tracked deportation.

The expedited removal program has raised concerns about the lack of due process, threatening individuals and families who have already established their lives and built communities in the US. It has been criticized for prioritizing speed over justice, stripping away protections that ensure vulnerable populations are treated with dignity and respect under US and international law.

To protect themselves, individuals should be aware of their rights, including the right to remain silent, not open the door, and not answer questions from ICE or CBP. They should also carry evidence of having been in the US for longer than two years and evidence of lawful entry or current lawful status.

Use of the National Guard

The use of the National Guard to carry out mass deportations has been a topic of discussion and concern during Donald Trump's presidency. Trump has repeatedly pledged to crack down on illegal immigration and has indicated that he will declare a national emergency and invoke the Insurrection Act and the Alien Enemies Act to carry out the largest deportation operation in American history.

The National Guard can be used for immigration enforcement with the approval of a state's governor. They can detain individuals, while other branches of the military can offer logistical support. The 287(g) program, added to the Immigration and Nationality Act in 1996, allows the Department of Homeland Security (DHS) to deputize state and local law enforcement to carry out immigration raids. While it has never been used to deputize members of the military, there are concerns that the Trump administration intends to use this program to involve the National Guard in immigration enforcement.

The Posse Comitatus Act prohibits federal armed forces from participating in civilian law enforcement activities unless authorized by Congress or the Constitution. This includes the National Guard if it has been called into federal service. However, the Insurrection Act is considered the primary exception to the Posse Comitatus Act, allowing the President to federalize and deploy the National Guard and active-duty armed forces anywhere in the country.

While the Alien Enemies Act does not authorize military deployment, when combined with the Insurrection Act, it could permit the militarized deportation of immigrants lawfully in the country under certain conditions. Trump's use of these acts would be unprecedented and has been criticized as an abuse of power and a violation of civil liberties.

It is important to note that the use of the military in immigration enforcement is not without precedent. In 2019, Trump declared a national emergency to redirect military funds to construct the US-Mexico border wall. More recently, President Joe Biden used a national emergency declaration to deploy the National Guard to the southern border for drug enforcement. However, it is unclear if Trump's advisors have comprehensively determined which authorities might be available for mass deportations.
