A US federal judge on Thursday prevented Philadelphia’s “ICE OUT” mandate from taking effect, holding that the law requiring Immigration and Customs Enforcement (ICE) agents to remove masks and display badges sidesteps a “clear constitutional mandate.” Trump-appointed Judge Chad Kenney’s ruling temporarily blocks the enforcement of the bill, which was set to go into effect on Tuesday, while the suit is pending. The ruling signals how federal courts will apply constitutional preemption doctrine to local sanctuary-city ordinances nationwide.
What changed
Bill No. 260060 is a piece of a seven-bill legislative package introduced in January of this year to counteract “violent” federal immigration enforcement, protect civil rights, and strengthen Philadelphia’s “Welcoming City” policies. The contested portion of the package requires all ICE agents to remain maskless, use marked vehicles, and identify themselves upon request. An officer could face up to 90 days in jail plus a fine for violating the ordinance.
Philadelphia Mayor Cherelle Parker signed six of the seven bills into law, but declined to sign Bill 260060, citing an advisory letter from City Solicitor Renee Garcia that expressed concerns over the legality of the bill, particularly on the city’s ability to regulate the conduct of federal agents when carrying out their duties under federal law. Despite her hesitation to sign, she did not veto the bill, instead allowing it to become law without her signature.
On June 18, 2026, the DOJ sued the city of Philadelphia, as well as Parker’s administration, seeking a preliminary injunction. U.S. District Judge Chad Kenney, at the request of U.S. President Donald Trump’s administration, issued a preliminary injunction barring Philadelphia from enforcing key provisions of the law against federal officers before they are scheduled to take effect on Tuesday.
Kenney cited the Supremacy Clause in his order, emphasizing that no state has the power to impede upon, burden, or change the directives of federal agents operating according to constitutional laws enacted by Congress. Kenney wrote that “this type of direct regulation of the federal government by a municipality is blatantly impermissible.”
Why it matters
For immigration practitioners and clients in Philadelphia, this ruling eliminates a key local-law tool that could have constrained ICE enforcement tactics. Had the ordinance taken effect, you could have advised clients that ICE agents entering homes or public places must display badges, use marked vehicles, and operate unmasked—creating friction and potential grounds to challenge an encounter or arrest on state-law grounds.
That defense is now blocked. Federal agents can continue to wear masks, and “facial coverings reduce the risk of officers’ personal identities being shared publicly, which helps ensure that officers’ privacy and safety, and that of their family members, remains intact,” according to ICE’s Philadelphia field office.
More broadly, federal judges have blocked similar mask-prevention legislation in California and Virginia, and the DOJ is awaiting a verdict in its suit against New Jersey. This pattern suggests courts will consistently strike down municipal attempts to impose operational restrictions on federal agents, even when wrapped in local public-safety or transparency language.
Way forward
-
Audit your local-ordinance defenses. If you have advised clients on sanctuary-city protections or local anti-masking rules, verify whether those rules remain enforceable in light of this ruling and similar decisions in other jurisdictions.
-
Document ICE operations carefully. With mask bans blocked, ICE agents will continue anonymous operations. If representing a client arrested by masked federal agents, preserve all evidence of the encounter (vehicle descriptions, witness names, timeline) for potential Fourth Amendment or state-law claims.
-
Monitor Philadelphia’s broader “ICE Out” package. The six bills Mayor Parker did sign—on raid restrictions, info-sharing bans, and citizenship-status discrimination—remain in effect. Understand which parts of the package survive and how they affect local police interaction with ICE.
-
Track similar litigation nationwide. Many major cities are attempting to establish themselves as “ICE-Free Zones.” As courts resolve these cases, the boundaries of what cities can do to restrict federal immigration enforcement will become clearer. Adjust client advice accordingly.
