Immigrants' Rights

Through litigation, legislation, public advocacy, and outreach, the ACLU of Massachusetts defends the constitutional rights of all people, regardless of where they came from.

The ACLU of Massachusetts is fighting back against cruel federal immigration practices and local anti-immigrant policies, and fighting for the rights of all Massachusetts residents to feel safe and free in their communities.

In the last decade, U.S. Immigration and Customs Enforcement (ICE) has detained and deported millions of people from the United States, no matter costs to civil rights and family unity.

The ACLU has been at the forefront of several major legal struggles on behalf of immigrants’ rights, focusing on challenging laws that deny immigrants access to the courts, impose indefinite and mandatory detention, and discriminate on the basis of nationality. In 2014, we won a federal class action lawsuit challenging the government’s overuse of “mandatory” immigration detention to imprison non-citizens – many of them longtime, lawful permanent residents – without bond while their immigration cases are pending. As of January 2015, thanks to a court order in this case, many people have been released from immigration detention and reunited with their families.

In addition, we challenge constitutional abuses that arise from immigration enforcement at the federal, state, and local levels. In 2017, the ACLU of Massachusetts contributed to a case addressing whether local and state officials who hold undocumented immigrants on “ICE detainer” are in violation of the Massachusetts state constitution and the U.S. Constitution. In a landmark ruling, the Supreme Judicial Court decided that our state and local law enforcement do not have the legal authority to detain people on ICE detainers alone.

When President Trump took office and began to enact his cruel anti-immigrant agenda, we were among his foremost challengers in the courts. In early 2017, our attorneys rushed to Boston’s Logan Airport to defend the rights of people subjected to the first Muslim travel ban. We secured one of the first rulings country to temporarily block this unlawful policy. Later, we filed major lawsuits challenging the “Remain in Mexico” program, reuniting families separated at the border from their loved ones. When the Biden administration continued to uphold this Trump-era policy, we continued to litigate to reunite families and end the policy once and for all. No matter who is in power, we will fight relentlessly for the rights of immigrants and asylum seekers.

Some of our most important cases challenged unlawful immigration policies that pre-dated Trump. In 2019, we secured a landmark victory to end a 20-year practice in New England of detaining immigrants by default, without a fair bond hearing. This ruling allowed potentially thousands of immigrants to be with their families while their cases proceed. The victory was affirmed with a 2021 ruling in a similar ACLU case at the First Circuit. In 2021, we also filed a lawsuit challenging the government’s practice of withholding records that may aid immigrants in the defense of their cases.

In Massachusetts, dozens of cities have implemented policies limiting local collaboration with federal deportation efforts. While each locality has decided for itself the scope of those limitations, the ACLU of Massachusetts – bolstered by its community partners and supporters – has worked in cities and towns to help immigrants feel safer and more welcomed. We advocated successfully for the Biden administration to end its ICE contract with the Bristol County Sheriff’s Department, which was notorious for reports of civil rights violations. We have also called for an end to 287(g) agreements, which deputize local law enforcement to act as federal immigration agents across Massachusetts. Finally, we filed lawsuits to protect detained immigrants who were at risk of contracting COVID-19.

After 20 years of advocacy, the ACLU helped to pass a historic bill permitting all qualified drivers to apply for a license, regardless of immigration status. Shortly thereafter, we defeated an effort to repeal the law at the ballot box. Our work didn’t stop there: The ACLU continues to bolster efforts to ensure the new law lives up to its promise through effective privacy regulations, public education, and outreach.

On Beacon Hill, we continue to advocate for statewide measures that expand and uphold the civil liberties and civil rights of immigrants, and combat public and private discrimination against them.

Guerrero Orellana v. Hyde et al

In September 2025, the American Civil Liberties Union of Massachusetts, together with the ACLU’s Immigrants’ Rights Project, the ACLU of New Hampshire, the ACLU of Maine, the law firm Araujo and Fisher, the law firm Foley Hoag, and the Harvard Immigration and Refugee Clinic, filed a class action lawsuit in federal court to challenge the widespread denial of bond hearings to people detained by U.S. Immigration and Customs Enforcement. As the complaint demonstrates, this denial upends decades of settled law and established practice in immigration proceedings. The complaint alleges that the U.S. Department of Homeland Security and the Department of Justice recently and abruptly began to misclassify people arrested by ICE inside the United States. DHS and DOJ started systematically reclassifying these people from the statutory authority of 8 U.S.C. § 1226, which usually allows for the opportunity to request bond during removal proceedings, to the no-bond detention provisions of 8 U.S.C. § 1225, which does not apply to people arrested in the interior of the United States and placed in removal proceedings. This case is brought on behalf of Jose Arnulfo Guerrero Orellana and a putative class of similarly situated individuals. Mr. Guerrero Orellana has been living in the United States for over a decade. He brings this case to vindicate his own right to a bond hearing — where an immigration judge can determine whether his detention is justified to protect the community or ensure his appearance in court — and that of thousands of other detainees in Massachusetts, Rhode Island, Maine, and New Hampshire who will be denied the opportunity to seek release on bond under the new legal ruling adopted by the executive branch. The complaint alleges that the government's new policy violates constitutional and statutory due process rights as well as the Administrative Procedure Act.
