As the Mamdani administration expands sanctuary protections, the City Council is setting up its own oversight structure
Oversight in the Shadow of Enforcement
In February 2026, Mayor Zohran Mamdani signed Executive Order 13, a sweeping directive that reaffirmed New York City’s sanctuary city status, banned ICE from entering city-owned properties without a judicial warrant, required major agencies to appoint privacy officers, and established an Interagency Response Committee to coordinate the city’s response in the event of a federal immigration crisis. The order was welcomed by immigrant advocacy organizations as a meaningful step toward protecting the approximately 500,000 undocumented immigrants who call New York City home. But the City Council, operating in its constitutionally defined oversight role, has moved to establish its own parallel review process — ensuring that the executive order is not merely a declaration of intent but a set of enforceable commitments subject to public accountability. The City Council’s oversight committee on sanctuary city compliance, according to reporting by City and State New York, is examining whether city agencies are actually following through on the protections the mayor has announced.
What the Executive Order Requires
Under EO 13, each major city agency had 14 days to appoint a privacy officer and conduct “Know Your Rights” training for staff on how to interact with federal immigration authorities. Agencies are required to certify compliance with sanctuary protections limiting information sharing. City property — including schools, hospitals, shelters, parking lots, and other public spaces — is designated as off-limits to federal authorities without a judicial warrant. The order also directs core agencies to develop and distribute training for city employees on how to respond when federal agents arrive seeking access to city facilities. The Mayor’s Office has distributed more than 30,000 multilingual flyers and booklets to faith institutions across the city explaining immigrants’ rights under both city law and the Constitution.
Why Council Oversight Matters
The history of sanctuary city implementation in New York City is not reassuring. Under Mayor Eric Adams, whose cooperation with the Trump administration’s immigration enforcement became a political scandal, city agencies were found to have shared information with federal authorities in ways that violated sanctuary protections. The Department of Correction’s cooperation with ICE on Rikers Island became a flashpoint in the 2025 mayoral race. The City Council’s move to establish its own review process reflects an institutional determination that compliance cannot be left entirely to the executive branch. “The Trump administration is waging a lawless and unaccountable campaign of terror against immigrants across the country and right here in New York City,” Mamdani said at the time he signed the executive order. The Council’s oversight posture suggests that even an administration that shares those values needs to be held to its own standards. The New York Civil Liberties Union has published a detailed civil rights agenda for the 2026 City Council session that includes specific recommendations for strengthening sanctuary law enforcement and creating a private right of action for violations. The New York Immigration Coalition praised EO 13 as a critical step forward while calling on the City Council to pass the New York City Trust Act, which would allow individuals harmed by sanctuary law violations to sue the city for damages.
