Anthony Brown’s Office Signals Legal Trouble Ahead for Maryland’s Police Mask Ban

By MDBayNews Staff

Maryland Attorney General Anthony Brown’s office is quietly warning Democratic lawmakers that their push to ban face coverings for law enforcement officers could collide with the U.S. Constitution—particularly when it comes to federal immigration agents.

The advisory opinion, dated January 21, 2026, issued by the Office of the Attorney General and signed by Assistant Attorney General Natalie R. Bilbrough, reflects the legal position of Attorney General Anthony Brown’s office.

The letter to Delegate Nicole A. Williams, Bilbrough analyzed Senate Bill 1 (SB 1), a proposal that would make it a crime for law enforcement officers to wear face coverings while performing official duties, subject to limited exceptions.

While Bilbrough stops short of calling the bill outright unconstitutional, her message is unmistakable: Maryland can regulate its own police—but it cannot dictate how federal officers do their jobs.

A Narrow Green Light, Followed by a Red Flag

Bilbrough’s letter opens with a careful affirmation of state authority. She notes that the General Assembly has broad police powers to regulate state and local law enforcement and even criminalize certain conduct when tied to public safety.

On that narrow point, Bilbrough concludes SB 1 is “not clearly unconstitutional” as applied to state and local officers.

But that reassurance quickly evaporates when the bill’s reach extends beyond Maryland’s jurisdiction.

According to Bilbrough, applying SB 1 to federal agents—such as Immigration and Customs Enforcement (ICE)—would “likely be unconstitutional” under the Supremacy Clause and the doctrine of intergovernmental immunity, which prohibits states from regulating federal operations.

Federal Law Trumps Symbolic State Action

The letter walks through established Supreme Court precedent, making clear that states may not interfere with federal functions, even indirectly. Bilbrough points out that:

• Federal immigration enforcement is an exclusively federal responsibility.
• Maryland cannot impose criminal penalties on federal officers performing lawful federal duties.
• Even cooperative agreements under Section 287(g) of federal immigration law do not give states authority to override federal operational standards.

In plain terms: Maryland can pass a law banning masks for its own officers—but it cannot arrest, prosecute, or otherwise regulate ICE agents for doing their jobs.

Bilbrough also notes that there is currently no federal requirement that ICE officers wear masks, which complicates—but does not solve—the constitutional problem. Even without a direct conflict, a state law that burdens federal enforcement could still be struck down if it interferes with federal objectives.

Legal Exposure—and Political Cover

Bilbrough’s conclusion is measured but revealing. While SB 1 may survive a facial constitutional challenge, she warns that enforcement against federal officers would likely fail in court and expose the state to litigation—much like similar efforts in other states.

That warning matters politically.

Democratic lawmakers backing SB 1 have framed the proposal as a transparency and accountability measure. But Bilbrough’s letter underscores a familiar pattern in one-party states: legislation driven by messaging rather than enforceable law, with courts left to clean up the aftermath.

The result is a bill that may satisfy activist demands but delivers little in practice—except legal risk and taxpayer-funded court fights.

A Pattern of Symbolism Over Substance

Bilbrough’s analysis highlights a broader issue in Annapolis: a willingness to test constitutional boundaries when it serves a political narrative, even when legal experts inside state government are signaling caution.

If SB 1 advances in its current form, Maryland lawmakers will do so fully aware that the state cannot enforce the law as written against federal officers—and that any attempt to do so would almost certainly fail.

That raises an uncomfortable question for supporters of the bill: is this about public safety and accountability—or about scoring political points in a deeply blue state where legal consequences are someone else’s problem?
