 Department of Justice sues Philadelphia over law banning masked federal agents and unmarked vehicles

 The Department of Justice has filed a lawsuit against the city of Philadelphia and several high-ranking local officials, challenging a municipal ordinance that prevents law enforcement officers from wearing facial coverings or utilizing unmarked vehicles to hide their identities. The federal government characterized the measure as unconstitutional, arguing that Philadelphia, Mayor Cherelle Parker, District Attorney Larry Krasner, and City Solicitor Renee Garcia are undermining constitutional order by attempting to restrict federal agencies from carrying out their duties.

The lawsuit asserts that long-standing legal precedent firmly establishes that local and state governments hold no authority to regulate the operations of the federal government. Federal attorneys noted the irony of Philadelphia—the birthplace of federal sovereignty principles—enacting legislation that seeks to impose criminal and civil liabilities on federal officers based on how they execute their assignments.

Approved by the Philadelphia City Council on April 23 and formally adopted on May 8 as part of an "ICE Out" legislative package, the local law bans all municipal, state, and federal personnel from wearing masks, face coverings, or any attire that obscures identity, outside of highly limited exceptions. The ordinance also bars the intentional hiding of badges, name tags, and labels, forbids the use of unidentified vehicles during official tasks, and mandates that officers immediately identify themselves to anyone being arrested or detained. Non-compliance is classified as criminal concealment.

Supporters of the ordinance, including local council members, have argued that public accountability is a vital component of democracy, especially concerning entities granted policing powers. Local prosecutors had previously issued stark warnings that federal agents violating the masking ban would face arrest, detention, and prosecution under local law.

In its legal challenge, the federal government argues that the municipal bill directly violates the Supremacy Clause of the U.S. Constitution, which dictates that federal law overrides conflicting state and local statutes. This legal strategy mirrors ongoing federal challenges against similar masking restrictions enacted in California and New Jersey. In the California case, a federal appeals court issued an injunction blocking the state's ban, concluding that the administration would likely succeed because state laws cannot directly regulate the conduct of the United States.

The filing of the lawsuit follows closely on the heels of another federal legal victory involving Philadelphia, in which an appeals panel ruled that federal Interior Department officials have the authority to modify a historical exhibit detailing enslaved individuals at the city's early presidential home.
