The last and most contested provisions of Massachusetts' PROTECT Act took effect on Tuesday, November 3, 2026 — the same day the state's voters were choosing between the governor who signed the law and the challenger who campaigned against parts of it. From today, most civil arrests, including immigration arrests, are prohibited inside Massachusetts courthouses and on courthouse grounds without a judicial warrant or court order; people held in the state's detention facilities gain new rights to legal access, information in their own language and notice of transfers; and state agencies face hard deadlines — 45 days, or 14 business days in urgent cases — to answer crime victims seeking U and T visa certifications. Governor Maura Healey signed the act on August 5, 2026, as Chapter 163 of the Acts of 2026. Because the Legislature designated it an emergency law, much of it took effect immediately, a second tranche followed on September 4, and the courthouse, detention and visa provisions were deliberately held to November 3 — today.

The law's full name explains its pitch: An Act Promoting Rule of Law, Oversight, Trust and Equal Constitutional Treatment — PROTECT. It is among the broadest state laws in the country limiting cooperation with federal civil immigration enforcement, and it does not hide what it is doing. It restricts where civil immigration arrests can happen, limits what state and local police, sheriffs and court staff may do for federal immigration officers, creates enforceable rights for people in detention, and gives residents new ways to sue officials — including federal immigration agents — in state court. What it does not do, its own defenders stress, is abolish federal immigration enforcement: Congress controls federal immigration law, and a judicial warrant or a criminal arrest still opens every door the act closes to a civil arrest.

What changes at the courthouse today
From November 3, the act prohibits civil immigration arrests inside courthouses and on courthouse grounds — defined broadly to include courthouse steps, plazas, walkways and contiguous parking areas controlled by the judicial branch — without a judicial warrant. The word 'judicial' is the hinge of the whole provision. U.S. Immigration and Customs Enforcement (ICE) usually relies on administrative warrants and detainers issued inside the executive branch; under the Massachusetts law, those papers are not enough at a courthouse — the warrant or order must come from a judge or magistrate. The protection is aimed at everyone who has business before a court: defendants, witnesses, victims and family members, any of whom can now attend a hearing without a civil immigration arrest waiting in the corridor — unless a judge has signed for it, or the arrest is a criminal one, which the act does not touch.

New rights for people held in detention
The November 3 provisions also rewrite what happens after an arrest, inside Massachusetts state and county detention facilities. Facilities must now give detained people written information, in their primary language, explaining their right to legal counsel, their right to decline interviews with state or federal law enforcement or consular officials, and how to contact a lawyer. They must provide confidential attorney-client telephone communications and free, regular and reasonable video access for legal consultations. They must keep records that let authorised lawyers and designated contacts locate a detained person, update those records after any transfer, and make reasonable efforts to notify counsel and designated contacts within six hours after a transfer. A public phone number must let callers confirm custody, and transportation to court hearings must be provided and documented. For families — including the state's Punjabi and South Asian immigrant families — the transfer-notice and custody-confirmation rules answer the most common fear in any detention case: not knowing where a detained relative has been taken.

Two family-facing tools in the act deserve plain statement. Parents can now pre-arrange standby guardianship for their children in case they are detained or deported by ICE, so a child's care does not wait on an emergency court filing. And employers must tell their employees within 48 hours of receiving notice of an I-9 audit of employment-authorisation documents by ICE — a provision that reaches directly into workplaces across the state. Alongside them, the U and T visa certification deadlines that start today are meant to end the open-ended waits that crime victims — whose cooperation prosecutors often need — faced when asking an agency to certify their status.

What was already in force: sensitive locations and the cooperation limits
The courthouse rule completes a map of protected places the act drew in its earlier phases. Most civil arrests, including immigration arrests, already require a judicial warrant or court order in public K-12 schools, charter, vocational-technical and agricultural schools; in child-care centres, family day cares and group care facilities licensed or funded by the Department of Early Education and Care; in health-care facilities, including the nonpublic areas of hospitals, community health centres, substance-use-disorder programmes and nursing homes; and on state property, including nonpublic areas of state buildings and land. Before the act, Governor Healey's Executive Order 650 had already prohibited ICE from making warrantless civil arrests in nonpublic areas of state facilities and prohibited the use of state property for immigration-enforcement staging, with added guidance for higher-education campuses and places of worship.

The cooperation limits, in force since September 4, are the act's other pillar. State and local officials cannot ask about a person's immigration or citizenship status without a reason connected to a specific criminal matter; they cannot detain or hold someone for an ICE pickup without a judicial order; and no one may be held solely on an immigration detainer beyond the time they would otherwise be eligible for release — language that writes into statute the Massachusetts Supreme Judicial Court's decision in Commonwealth v. Lunn. Police departments, sheriffs' departments and the courts generally may not share a person's nonpublic personal information, custody status or advance notice of release with federal immigration authorities, except where federal or state law requires it, a judicial warrant, court order or treaty allows it, or a permitted intergovernmental agreement covers it. State and local agencies are barred from entering new agreements under section 287(g) of the federal Immigration and Nationality Act — the programme that deputises local officers for federal immigration enforcement — except in narrow circumstances. Joint guidance for implementing the law has been issued to every police department, including dispatch and records staff, by the Executive Office of Public Safety and Security, the Municipal Police Training Committee and the Massachusetts Chiefs of Police Association.

Accountability — and the sheriffs' pushback
The act arms its own enforcement. People can now sue government officials, including ICE agents, in Massachusetts state court for violating their federal constitutional rights, according to the administration's overview. The Attorney General — currently Andrea Joy Campbell — can sue if federal troops interfere with voting or if ICE arrests anyone in a protected location, including a courthouse. The Healey-Driscoll administration and the Attorney General have also opened an official portal, at mass.gov/fedmisconduct, where residents can report suspected misconduct by federal immigration enforcement agents, with photographs and video. A new state commission on immigration matters, created by the provisions taking effect today, will study and recommend on immigration questions for three years — including funding for immigration legal defence and protecting other safe spaces such as playgrounds, summer camps and public libraries; one of its seats is appointed by the Massachusetts Sheriffs' Association.

That seat exists because the sheriffs are the act's loudest institutional critics. Twelve Massachusetts sheriffs, including Bristol County Sheriff Paul Heroux and Plymouth County Sheriff Joseph McDonald, wrote to Governor Healey on October 22 asking her to change the part of the law that bars jails from giving federal immigration agents advance notice when some people held before trial are released, the State House News Service reported. The law does allow advance notice in one carved-out case: when a person completes a sentence for listed serious offences, including violent felonies causing serious bodily injury, sex offences, serious class A or class B drug offences, some firearms offences and abuse offences. The sheriffs' concern is the pretrial category, and they named three routes to a change — a new law, a regulation or an administrative step. The dispute reached the governor's race on October 27, when Republican candidate Mike Minogue accused Healey of ignoring the sheriffs and Healey said she would keep talking with them. Massachusetts voters delivered their own verdict on that argument today, in a race whose polls closed at 8 p.m.

It does not ban every courthouse arrest: criminal arrests proceed as before, and a civil arrest backed by a judicial warrant or court order is lawful anywhere in the state. It does not — and, its analysts note, cannot — repeal federal immigration law or strip federal officers of powers federal law gives them. What it controls is Massachusetts' own officers, buildings, jails and information, and the places where a civil arrest may happen without a judge's signature.
What happens next
Implementation is now the story. Police and court officers across Massachusetts work from the joint state guidance; detention facilities must be running the intake, language-access, video-access and six-hour transfer-notice systems from today; and agencies answering U and T visa certification requests are on the 45-day clock for the first time. The courthouse provisions will be tested case by case — legal analysts who have tracked the act note that courthouse warrant records, which the chief justice's office must keep and publish, will show by next July 1 how the rule worked in its first months. The sheriffs have promised to keep pressing for their amendment, the new commission has three years to report, and a federal legal challenge to the act — the standard next step for a state law this broad against a federal enforcement programme — remains a live possibility that no filing had yet settled as of today. For Awaaz Punjab's readers in Massachusetts, the practical takeaways start now: a court date is no longer, by itself, an immigration-arrest risk without a judge's warrant; a detained relative must be findable through the facility's custody line; and suspected misconduct by a federal agent has an official state reporting address.
