U.S. District Judge Chad Kenney issued a preliminary injunction Thursday blocking Philadelphia from enforcing its mask ban and related restrictions against federal law enforcement officers, the latest in a string of federal court losses for cities and states that tried to dictate how federal agents carry out immigration operations.
The ruling came just days before Philadelphia's ordinance, Bill No. 260060, was set to take effect on Tuesday. The Justice Department had sued the city last month, calling the measure a "blatantly unconstitutional" attempt to regulate federal agents. Judge Kenney agreed, grounding his decision in the Supremacy Clause, the constitutional provision that establishes federal law trumps state and local law when the two conflict.
Philadelphia joins California and Virginia on a growing list of jurisdictions that passed laws targeting masked federal officers only to see those laws blocked by federal courts. The pattern is clear: progressive cities keep passing these measures, the DOJ keeps suing, and federal judges keep ruling the same way. The Constitution hasn't changed. The outcome hasn't changed. But the political impulse to obstruct federal immigration enforcement apparently hasn't changed either.
Philadelphia City Council passed Bill No. 260060 earlier this year as part of a larger legislative package. The measure would have banned covered officers, local, state, and federal, from wearing masks or shielding their identities while on duty and interacting with the public. Officers would have been required to wear visible badges and use marked vehicles in certain circumstances.
Exceptions carved out room for medical masks, religious coverings, certain tactical equipment, and hazardous conditions. But the core prohibition applied broadly. Officers who violated it could face civil and criminal penalties.
The council passed the bill amid a national debate over masked immigration agents conducting enforcement operations in communities. In Minneapolis in January, masked immigration agents were documented shooting people, including two U.S. citizens. That incident fueled calls across several blue-state legislatures to restrict how federal officers identify themselves.
Philadelphia Mayor Cherelle Parker, a Democrat, declined to sign the bill. Her city solicitor's office informed her it presented significant legal problems. But Parker did not veto it, either. She allowed it to become law in May without her signature, a move that let the measure take effect while keeping her fingerprints off it.
Judge Kenney did not mince words. As Fox News Digital reported, the judge wrote that the city council had overstepped a constitutional boundary that has been settled for more than two centuries:
"When the Philadelphia City Council voted to pass Bill No. 260060... it attempted to sidestep the Constitution's clear mandate and disregarded this fundamental principle of law that has informed American jurisprudence for over 200 years."
Kenney went further, spelling out what endorsing Philadelphia's position would mean in practice:
"Endorsing the City of Philadelphia's position would mean... municipalities could decide whether to pass their own laws regulating how, when, where, and whether federal law enforcement officers can conceal their identities."
He called the ordinance what it was.
"This type of direct regulation of the federal government by a municipality is blatantly impermissible."
That language leaves little room for ambiguity. A city cannot tell federal agents how to dress, what vehicles to drive, or whether to display their names during enforcement operations. The Supremacy Clause exists precisely to prevent that kind of local interference with federal authority.
In an unusual move, Judge Kenney singled out Mayor Parker for her decision not to sign the bill. He said she had "acted with civic wisdom and courage to stand up for the Constitution and follow the rule of law where it led."
That's notable. Parker is a Democrat in a deep-blue city. She didn't veto the measure. But she recognized, or at least her lawyers recognized, that the bill was legally doomed. Her refusal to sign it put her at odds with her own city council and with the progressive base that pushed for the restrictions.
Whether Parker deserves credit for quiet constitutional fidelity or criticism for not vetoing a bill she knew was legally defective is a fair question. She threaded a political needle. The judge chose to reward the result rather than scrutinize the method.
Philadelphia's loss is not an isolated event. It fits a pattern that has played out across multiple states this year.
In February, a federal judge halted a California law that prohibited federal officers from wearing masks while on duty. On Tuesday, just two days before the Philadelphia ruling, a federal judge blocked a new Virginia law barring federal law enforcement from wearing masks. The DOJ has also sued New Jersey to block a similar mask ban targeting federal officers.
In every case where a court has ruled, the result has been the same: the local or state restriction gets blocked. The legal reasoning is the same, too. The Supremacy Clause does not bend because a city council or state legislature disagrees with how the federal government enforces immigration law.
The Justice Department, in a statement to Reuters, made clear it intends to keep pressing the issue. The DOJ said it "will keep fighting jurisdictions that try to obstruct President Trump's immigration enforcement with policies that endanger agents and public safety."
Every one of these lawsuits costs taxpayer money. Philadelphia's city attorneys had to defend a bill their own solicitor's office flagged as legally problematic. California, Virginia, and New Jersey have spent, or will spend, public resources defending measures that federal courts have consistently struck down.
The city councils and state legislatures passing these laws know the legal landscape. They have watched the same Supremacy Clause arguments succeed in courtroom after courtroom. Yet they keep passing the same kind of legislation, often as part of broader packages designed to signal resistance to federal immigration enforcement.
The bills serve a political purpose. They tell a progressive constituency that local leaders are "doing something" about masked federal agents. But the doing amounts to nothing once a federal judge applies settled constitutional law. The only tangible product is legal fees and a court order saying what everyone already knew.
Fox News Digital reached out to both the city and the Justice Department for comment on Thursday's ruling. The DOJ's statement to Reuters spoke for itself. Philadelphia's response, if any, was not reported.
The preliminary injunction blocks enforcement of the ordinance against federal officers while the underlying lawsuit proceeds. Whether Philadelphia will appeal remains an open question. So does the status of the DOJ's lawsuit against New Jersey.
But the trajectory is unmistakable. Federal courts have now blocked these mask-ban laws in California, Virginia, and Philadelphia. No jurisdiction has successfully enforced one. The constitutional principle at stake, that cities cannot regulate how federal officers conduct federal operations, is not novel or contested in serious legal circles. It is bedrock.
Progressive officials can keep passing these bills. Federal judges will keep blocking them. And taxpayers in those cities will keep footing the bill for legislation that was never designed to survive a courtroom, only a press conference.
