NY Gov. Hochul Signs First State Statutory 287(g) Ban and ICE Mask Prohibition Into Law

New York Governor Kathy Hochul signed a package of immigration protection measures into law on May 29, 2026, establishing what appears to be the first state statutory ban on 287(g) formal cooperation agreements between local governments and ICE enacted during the second Trump administration. The law also prohibits local jails from holding detainees on ICE civil detainer requests, bans ICE agents from wearing masks during enforcement operations, and protects sensitive locations — hospitals, schools, childcare centers, polling places, and churches — from ICE enforcement without a judicial warrant. Hochul signed the measures as part of a budget compromise; the legislation fell short of the broader “New York for All Act” that would have banned both formal and informal ICE cooperation. State Senator Julia Salazar indicated advocates would continue pushing for stronger protections in the remaining session. A Pace University Law professor warned that some provisions may face constitutional preemption challenges.

The NY signing directly counters the 287(g) escalation pattern that is one of the core structural mechanisms of the Trump detention-pipeline buildout: 287(g) agreements nationwide rose from approximately 135 in January 2025 to 1,427 by February 2026 — a tenfold increase in 13 months. New York’s statutory ban is a novel state-level instrument, distinct from executive sanctuary policies, because it requires legislative override to reverse and creates a legal record for preemption litigation. The mask-ban and sensitive-location provisions are also novel resistance mechanisms with no direct precedent in prior state sanctuary legislation. The law represents the most significant blue-state legislative action against the ICE enforcement apparatus in the sweep window, extending the documented red-vs-blue state ICE enforcement divide into statutory form. Cross-reference with the Hochul/Mullin federal-state cooperation tensions and the Delaney Hall hunger strike (2026-05-26–delaney-hall-newark-hunger-strike-geo-group-protests-pepper-ball-clashes-sen-andy-kim) — New Jersey and New York are both in the ICE enforcement confrontation zone.
