Massachusetts Draws a Line Against ICE as New PROTECT Act Reshapes Policing 

Mariachi music filled a crowded community center in Chelsea as Massachusetts Gov. Maura Healey signed one of the country’s most expansive state immigration laws. For the families gathered inside La Colaborativa, the ceremony carried significance far beyond politics. 

In Chelsea, where more than 40 percent of residents were born outside the United States, immigration enforcement is not an abstract national debate. It can determine whether a parent takes a child to school, a patient visits a clinic or a witness appears in court. 

The Promoting Rule of Law, Oversight, Trust and Equal Constitutional Treatment Act, commonly called the PROTECT Act, took effect immediately after Healey signed it on August 5, 2026. The law limits how Massachusetts institutions and law enforcement agencies may participate in federal civil immigration enforcement. 

“The law I’m signing today is a public safety law,” Healey said during the signing ceremony. She argued that residents should not be afraid to send their children to school, seek medical treatment, report crimes or appear in court. 

The law does not remove Immigration and Customs Enforcement from Massachusetts or prevent federal agents from enforcing federal immigration law. Instead, it establishes strict conditions governing where civil immigration arrests may occur and how state and local authorities may assist. 

A Courthouse Visit Should Not Become a Trap 

One of the law’s central provisions prohibits civil immigration arrests inside or on the grounds of state courthouses without a judicial warrant or court order. 

That distinction matters because ICE commonly uses administrative warrants issued by immigration officials rather than judges. The PROTECT Act requires authorization from a judge or magistrate before a civil immigration arrest may occur at a protected location. 

Supporters say courthouse arrests can discourage victims, witnesses and defendants from participating in the justice system. Someone who fears detention outside a courtroom may avoid reporting abuse, seeking a restraining order or appearing in a pending case. 

Lisa Maya Knauer, a University of Massachusetts Dartmouth anthropologist who works with immigrant communities, said courthouse protections were among the law’s most important provisions. 

“That’s where people have the most anxiety right now,” Knauer said when discussing the effect of courthouse immigration arrests. She said the fear surrounding such arrests had reduced some residents’ willingness to report crimes. 

The law extends similar protections to public schools, child care facilities, hospitals, clinics and doctors’ offices. Civil immigration arrests generally cannot occur at those locations without a warrant signed by a judge or magistrate. 

Schools and child care facilities must also establish procedures for responding when immigration agents arrive. Those plans will include identifying designated staff members, verifying warrants, documenting encounters and notifying families when appropriate. 

Places of worship were included in earlier proposals but were removed from the final legislation. 

Local Police Will Face Firm Limits 

The PROTECT Act draws a clearer boundary between local policing and federal immigration enforcement. 

State and local officers generally cannot ask about a person’s immigration or citizenship status during an ordinary encounter unless the information is relevant to a criminal investigation. They are also restricted from using public personnel, facilities, or other resources to conduct federal civil immigration enforcement. 

The law codifies the Massachusetts Supreme Judicial Court’s 2017 decision in Lunn v. Commonwealth. That ruling found that Massachusetts officers lacked authority to hold someone solely based on a federal civil immigration detainer after the person would otherwise be eligible for release. 

The new statute also restricts future agreements established under Section 287(g) of federal immigration law. Those agreements allow ICE to delegate certain immigration enforcement responsibilities to trained state or local officers. 

The law does not impose an absolute ban on every new 287(g) agreement. New agreements require gubernatorial approval, and the Massachusetts Department of Correction’s existing agreement with ICE remains exempt. 

That distinction is important because Massachusetts is limiting local participation without claiming the authority to abolish a federal immigration program. 

The final 43-page version of the PROTECT Act also requires state officials to publish multilingual guidance explaining how schools, police agencies and other institutions should respond to civil immigration enforcement. 

The Human Cost Behind the Legislation 

Chelsea City Manager Fidel Maltez said fear surrounding immigration enforcement had already changed daily life in the city. 

“We in the city have seen the cost of that fear: empty classroom seats, neighbors who have left the state, businesses that have shuttered, and trust broken between residents and our institutions that are meant to protect them,” Maltez said at the Chelsea ceremony. 

For immigrant parents, one of the law’s most personal provisions concerns what happens to their children if a caregiver is detained or deported. The act allows parents to arrange guardianship in advance, giving a trusted adult legal authority to care for a child if the parent suddenly becomes unavailable. 

The provision could prevent families from having to make critical decisions during the first chaotic hours after a detention. A designated guardian may be able to handle school, medical, and travel matters that someone holding a temporary caregiver affidavit could struggle to manage. 

Employers also receive new responsibilities. Businesses must notify workers within 48 hours after receiving notice of a federal inspection of employment eligibility records, commonly known as an I-9 audit. 

The law further requires certain authorities to process certifications connected to U and T visa applications within established periods. Those visas may be available to qualifying victims of specified crimes or human trafficking who assist law enforcement. 

Supporters argue that these provisions will encourage residents to report crimes and cooperate with police without believing that asking for help will automatically expose them to civil immigration enforcement. 

Critics Warn of a Public Safety Risk 

Republican lawmakers, federal officials and immigration enforcement supporters argue that the law could make cooperation between agencies more difficult. 

Brian Shortsleeve, a Republican candidate for governor, accused Healey of placing politics ahead of public safety. He argued that transferring a person to federal custody at a courthouse may be safer than requiring ICE agents to locate that individual elsewhere. 

“When politicians bar local law enforcement from working with the Department of Homeland Security, our law enforcement officers have to have a more visible presence so that we can find and apprehend the criminals let out of jails and back into communities,” a department spokesperson said in a response to the new Massachusetts restrictions. 

The criticism requires context. The law does not prohibit cooperation in criminal investigations, invalidate judicial warrants or prevent ICE from operating in Massachusetts. Its principal restrictions concern civil immigration enforcement and the use of state or local resources. 

Supporters maintain that public safety suffers when residents are too frightened to call police, attend court or seek medical treatment. Critics counter that limiting cooperation may force federal officers to conduct arrests in less controlled public settings. 

The disagreement is expected to continue as state institutions begin applying the law alongside existing federal immigration authority. 

A Law That Will Be Tested Beyond the Signing Room 

The PROTECT Act creates a state legal claim for people whose federal constitutional rights are violated by government officials, including federal immigration officers. Successful plaintiffs may pursue remedies in Massachusetts courts, although federal officials may still raise applicable legal defenses. 

The measure also directs agencies to document encounters with immigration officers and provide public information in multiple languages. It establishes a commission to examine the continuing needs of immigrant communities across Massachusetts. 

Still, a statute cannot immediately remove the anxiety that has settled over many families. Helena DaSilva Hughes, president of the Immigrants’ Assistance Center in New Bedford, welcomed the law but questioned whether it would quickly reassure residents who fear federal enforcement. 

“It gives a real positive message, but at the same time I’m not sure that it is going to ease the anxieties of our immigrant families,” she said while discussing what the legislation could mean for local families. 

That uncertainty may be the law’s first real test. Massachusetts has drawn a firm legal boundary, but its effectiveness will depend on how police departments, schools, hospitals, courts and federal agents respond when the next difficult encounter occurs. 

At the Chelsea ceremony, La Colaborativa Executive Director Gladys Vega captured the immediate change in simpler terms: “Before, they were coming and we didn’t have anything to hit them with. Now, we have the law.”
