Maryland House approves limits on local cooperation with federal immigration detainers after hours of debate

The Maryland House of Delegates passed House Bill 1017 on third reading on March 27, 2026, after extended floor questioning of the bill’s sponsors and opponents. The bill—titled in the House as “correctional services, private immigration detention facilities, zoning requirement”—prohibits private entities from operating private detention facilities in Maryland and narrows routine cooperation by state and local correctional facilities with federal immigration authorities to specified, convicted individuals. The clerk announced the final tally: “There being 95 votes in the affirmative and 36 votes in the negative,” the bill was declared passed.

Supporters said the bill creates a single statewide standard that preserves criminal prosecutions and prevents non‑convicted people from being deported before they face trial and, if convicted, serve state sentences. “We want to process them on the crime that we have evidence of,” the committee chair said on the floor, stressing the bill’s focus on convicted offenders and on ensuring victims see prosecutions through.

Opponents warned the proposal raises operational uncertainties and could clash with federal practices. Members repeatedly questioned whether the federal government could still build a facility in Maryland and then later contract operations to a private firm—a scenario the floor leader and sponsors said would create a statutory conflict the state could not authorize. One delegate asked whether a federal facility that later used private contractors to staff operations would be treated as a private detention center under the bill; sponsors replied that the bill bars private entities from obtaining local approval to operate private jails but cannot block federal facilities or wholly control federal contracting decisions.

The debate turned to procedural mechanics: the bill requires state correctional facilities to provide written notice to federal immigration authorities within 48 hours of release for individuals who meet the bill’s convicted‑offender thresholds, while asking local jails to avoid routine inquiries into citizenship or place of birth except as needed for booking. Several members raised a drafting and practice concern: routine booking and fingerprinting feed the federal CJIS database, and that booking often includes country or place‑of‑birth information. A member stated that “information that is pertinent to a routine booking procedure” remains permitted under the bill’s exceptions, a point sponsors used to say the measure does not bar ordinary booking practices.

Members also debated whether administrative detainers (civil requests from federal immigration authorities) should be enough to hold or prolong detention absent judicial authorization; sponsors said the bill was crafted to require a higher threshold—conviction or judicial warrant—before full cooperation. The minority leader and other members argued the change could hamper federal terrorism or serious‑crime investigations in which federal agencies might need immediate access; supporters replied that federal law enforcement retains means to pursue proven threats, including judicial warrants, and that the bill’s protections primarily prevent deportations of non‑convicted people for minor offenses.

Several members asked about the law’s readiness for emergency enactment and whether counties that previously cooperated extensively with ICE would face penalties if they had earlier contacts; committee leaders said the provision creating a statewide policy was intended to replace a patchwork of local practices but acknowledged questions of timing and operational implementation remain for agencies and courts.

The House rejected an amendment that would have renamed the measure (the amendment failed on a 91‑negative vote), then adopted the underlying motion and recorded the final passage vote. The bill’s sponsors said judges should still consider immigration status where relevant in bail and detention hearings, and they emphasized the bill’s stated intent to safeguard due process before deportation.

What happens next: HB 1017 will be sent to the Senate or the Governor as required under the legislative calendar (procedural steps depend on cross‑chamber action already taken). Implementing regulations, guidance to sheriffs and corrections departments, and potential litigation over federal‑state conflicts were all raised as likely near‑term follow‑ups on the floor.
