Massachusetts Legislature Advances PROTECT Act to Limit Local Immigration Enforcement Cooperation
Why It Matters
Massachusetts lawmakers are working to finalize legislation that would restrict how state and local law enforcement agencies cooperate with federal immigration authorities. The PROTECT Act has cleared both chambers of the Massachusetts Legislature and now heads to a conference committee to resolve differences between the House and Senate versions before it can reach Gov. Maura Healey’s desk.
Supporters argue the bill is especially timely given a recent report indicating that Massachusetts law enforcement agencies have been regularly coordinating with federal immigration officials — a practice the legislation is designed to curtail.
What Happened
The Massachusetts House passed the PROTECT Act by a wide margin in late March. The Senate followed earlier this month with its own version of the bill. The two chambers must now reconcile their competing versions through a conference committee before sending a final bill to the governor.
The legislation would require that individuals in custody be informed of their right to legal counsel and their right to refuse conversations with federal authorities absent an attorney. It would also designate courthouses as protected spaces where immigrants — including those with lawful standing contesting minor civil matters — could appear without risk of immigration enforcement action.
Additionally, the bill would prohibit police officers from asking about immigration status unless compelled by law or a judicial warrant.
By the Numbers
- Nearly 20% of Massachusetts residents are immigrants — the seventh-highest share among all U.S. states.
- Immigrants in Massachusetts contribute an estimated $20 billion in annual tax revenue.
- Illegal immigrants account for roughly $1.4 billion of that annual tax contribution, according to figures cited by the bill’s advocates.
- Counties with sanctuary policies report median incomes approximately $4,400 higher and poverty rates more than two percentage points lower than non-sanctuary counties, according to research cited in support of the legislation.
The Policy Debate
Proponents of sanctuary-style policies contend they make immigrant communities more willing to report violent crimes and cooperate with local police, ultimately improving public safety. They also point to economic data suggesting that communities with such policies tend to outperform those without them on key measures.
Critics counter that limiting cooperation between local agencies and federal immigration enforcement undermines national immigration law and creates jurisdictional conflicts. Opponents have pointed to instances where individuals with criminal records were shielded from federal detainer requests under sanctuary policies. Research on sanctuary policies and crime rates has produced mixed findings, and the political debate over their effectiveness remains active at both the state and federal levels.
Advocates note that even in sanctuary jurisdictions, local police typically work with Immigration and Customs Enforcement in cases involving felony convictions or judicial arrest warrants — meaning the PROTECT Act would not fully sever law enforcement cooperation with federal authorities.
A recent federal court ruling involving Colorado’s sanctuary policies affirmed their legality, a development supporters of the Massachusetts bill have cited as further grounding for moving forward. Massachusetts lawmakers interested in related policy tradeoffs have also been examining the state’s approach to energy costs; some critics argue Massachusetts progressives have been slow to prioritize affordability in adjacent policy debates.
Zoom Out
The Massachusetts bill reflects a broader national pattern in which Democratic-led states have moved to codify limits on local immigration enforcement cooperation, often in direct tension with federal enforcement priorities under the current administration. Several states, including California, Illinois, and New York, have enacted similar laws in recent years.
At the federal level, the Trump administration has pushed to expand cooperation between local law enforcement and ICE, including through financial incentives and legal pressure on jurisdictions that resist. That tension has produced ongoing litigation in multiple states and raised unresolved constitutional questions about the extent of federal authority to compel local enforcement participation.
Massachusetts, with one of the country’s largest immigrant populations, sits at the center of that national debate. The state has been experiencing net population outflows in recent years, and immigration has helped offset some of that demographic pressure — a point raised by supporters of the PROTECT Act. Former Massachusetts Congressman Barney Frank, a longtime advocate for immigrant communities, shaped much of the state’s progressive policy tradition on civil liberties issues that now informs debates like this one.
What’s Next
A House-Senate conference committee will work to align the two versions of the PROTECT Act. If conferees reach agreement and both chambers approve the final version, the bill will move to Gov. Healey, who has not yet publicly announced her position on the reconciled measure. The current legislative session sets the timeline for how quickly that process can move.
