Maryland Bans 287(g) — But Sheriffs Aren’t Backing Down. Now Comes the Legal War.

By Michael Phillips | MDBayNews

Maryland is about to test the limits of federalism — and taxpayers may be the ones footing the bill.

Gov. Wes Moore is expected to sign legislation ending Maryland’s participation in federal 287(g) agreements — the partnerships that allow local law enforcement agencies to cooperate directly with Immigration and Customs Enforcement (ICE) in identifying and processing certain undocumented immigrants in custody.

But there’s a problem.

Sheriffs in nine Maryland counties have already said cooperation with ICE will not stop.

They plan to formally comply with the state law by terminating the agreements — while continuing to cooperate with federal immigration authorities in what they describe as “informal” or otherwise lawful ways.

Translation: This fight is far from over.

What Is 287(g), Really?

Section 287(g) of the Immigration and Nationality Act allows the federal government to deputize trained local officers to perform limited federal immigration enforcement functions.

Participation is voluntary.
Termination is voluntary.

And here’s the key: cooperation with federal authorities outside of 287(g) is still legal under federal law.

So when Maryland bans formal agreements, it doesn’t automatically outlaw all communication or cooperation between sheriffs and ICE. It just ends the structured, signed partnership.

Which raises the obvious question:

What happens if a sheriff continues cooperating anyway?

The Constitutional Collision Course

There are three legal principles about to collide:

1. Federal Supremacy

Under the Supremacy Clause of the U.S. Constitution, federal immigration law preempts conflicting state law. Immigration enforcement is a federal power.

2. Anti-Commandeering Doctrine

States cannot be forced by the federal government to enforce federal law (see Printz v. United States). But they also cannot obstruct federal enforcement.

3. State Authority Over Local Officials

Sheriffs in Maryland are state constitutional officers. The state legislature can regulate aspects of their duties — but only within constitutional limits.

Now here’s where it gets messy.

If Maryland prohibits formal cooperation agreements but a sheriff continues to voluntarily share information with ICE, honor federal detainers within legal bounds, or communicate about individuals in custody — is that illegal under state law? Or protected under federal supremacy?

Expect lawsuits to answer that.

What Could Actually Happen to a Sheriff?

Here are the realistic legal scenarios:

• State Civil Enforcement

Maryland’s Attorney General could attempt to sue a county or sheriff for violating state law if they continue prohibited cooperation.

• Injunctions

A court could issue an injunction ordering compliance.

• Budget Leverage

The state could attempt to restrict funding streams tied to compliance.

• Federal Counter-Suits

Counties or sheriffs could file suit arguing that the state law unlawfully interferes with federal immigration enforcement or violates constitutional principles.

• Declaratory Judgment Actions

Expect at least one sheriff to seek a court ruling clarifying what level of cooperation remains lawful.

This won’t be resolved in press conferences. It will be resolved in federal court.

The Political Theater vs. The Legal Reality

Democratic lawmakers frame the bill as protecting civil liberties and preventing local law enforcement from acting as immigration agents.

But sheriffs argue something simpler:

If someone is already in jail for a crime and ICE wants to know about it, why would local authorities refuse to communicate?

Ending 287(g) doesn’t deport anyone by itself. It just changes the mechanism.

So what’s really happening here?

Symbolic politics colliding with operational law enforcement.

And the timing is hard to ignore. With national immigration debates escalating, Maryland Democrats appear eager to stake out ideological territory — even if it triggers a multi-layered legal fight.

The Likely Outcome

Here’s the blunt assessment:

1. Formal 287(g) agreements will end.
2. Informal cooperation will continue in some counties.
3. Activist groups will pressure the Attorney General to enforce the ban aggressively.
4. At least one county will challenge the state in court.
5. Taxpayers will pay for both sides.

Meanwhile, federal immigration enforcement will continue regardless of Annapolis messaging.

The Bigger Question

If immigration enforcement is a federal responsibility, and local cooperation is voluntary, what exactly is Maryland trying to accomplish?

Is this about public safety?

Or is it about political positioning?

Because if the end result is years of litigation, strained state-county relations, and uncertainty for law enforcement officers trying to follow the law — then the only certainty is more chaos.

Maryland may have just invited a constitutional showdown.

And once that starts, it won’t be resolved by hashtags.
