Case Summary

The State of Maryland brought this action seeking declaratory and injunctive relief under the Administrative Procedure Act (APA), 5 U.S.C. § 701 et seq., and the National Environmental Policy Act (NEPA), 42 U.S.C. § 4321 et seq., to halt the government's unlawful decision to establish a massive immigration detention facility in Washington County, Maryland.  On January 16, 2026, Defendants U.S. Department of Homeland Security (DHS) and U.S. Immigration and Customs Enforcement (ICE) purchased a v…

The State of Maryland brought this action seeking declaratory and injunctive relief under the Administrative Procedure Act (APA), 5 U.S.C. § 701 et seq., and the National Environmental Policy Act (NEPA), 42 U.S.C. § 4321 et seq., to halt the government's unlawful decision to establish a massive immigration detention facility in Washington County, Maryland.  On January 16, 2026, Defendants U.S. Department of Homeland Security (DHS) and U.S. Immigration and Customs Enforcement (ICE) purchased a vacant commercial warehouse just outside of Williamsport, Maryland —a town with a population of just over 2,000 individuals—with the intention of converting it into an immigration detention facility outfitted with 1,500 beds. The plaintiff alleged that converting the Williamsport Warehouse into a massive immigration detention facility will have predictable impacts on the environmental, economic, and public health and safety interests of the State of Maryland. Among other things, the construction of the detention center is likely to harm the state’s natural resources and environment—including a waterway that is a tributary to the Potomac River and important habitat to State protected species. Further, public reporting of conditions in detention facilities around the country reveals concerning evidence of a measles outbreak, sewage problems, and generally unsanitary conditions—alarming data that would implicate State public health authorities as well.

Accordingly, the state of Maryland brought this suit in the District of Maryland seeking a declaration that the construction of the immigration facility is unlawful and a court order enjoining the government from purchasing the warehouse for the purpose of converting it into an immigration detention facility. The case was assigned to U.S. District Judge Brendan Abell Hurson.

On March 10, 2026, the plaintiff state filed a motion for an ex parte temporary restraining order, which asked the court to restrain and enjoin the defendants from proceeding with construction activities to convert the Williamsport Warehouse into an immigration detention facility during the length of the order. The plaintiff also asked the court to require the defendants to file a status report describing the steps of their compliance with the order. 

The next day, on March 11, the court granted the temporary restraining order. The court first found that the plaintiff was likely to succeed on the merits because the defendants were likely required under NEPA to issue an environmental impact statement or conduct an environmental assessment because their plans constituted a major federal action and a final agency action. Next, the court found that the State was likely to suffer irreparable harm in the absence of a TRO because it showed significant evidence that the construction necessary to convert the warehouse into an ICE facility posed a serious risk to the nearby watersheds and ecosystem, which would affect several state-listed endangered species. The court finally found that the balance of the equities and public interest supported the issuance of a TRO because the irreparable harm the plaintiff faced and the risk of harm to human health and the environment outweighed the slight inconvenience of a delay in construction. Consequently, the court granted the TRO, which restrained the defendants from proceeding with converting the Warehouse for a period of fourteen days. The court additionally ordered the defendants to file a status report within forty-eight hours of the order describing their compliance. 2026 WL 691507

On March 19, 2026, plaintiffs filed a motion for a preliminary injunction. Similar to the TRO, the PI sought to enjoin the Defendants from the construction activities required to convert the Williamsport Warehouse, or to utilize the warehouse as an immigration detention facility, and to continue the requirement of status reports. The court held a hearing on the motion on April 15, 2026, and granted the motion that same day. In a memorandum opinion issued April 17, 2026, the court detailed its reasoning, noting that the case is a “crystal-clear example” of a federal agency failing to comply with the requirements of the National Environmental Policy Act. The court first concluded that the plaintiffs are likely to succeed on the merits of their claims, finding that the decision of the Defendants not to conduct an environmental assessment and to subject the project to a categorical exclusion was likely arbitrary and capricious in violation of the APA. Second, the court reasoned that the plaintiffs showed the requisite irreparable harm as the conversion of the warehouse would pose environmental harm from the necessary excavation required to upgrade the facility or from the sewage backups and overflows that would occur from a line currently designed to accommodate 4 toilets having to serve a 1,5000 person detention center. Last, the court found the balance of the equities and public interest to favor the plaintiffs as the preservation of the status quo of immigration enforcement in Maryland outweighs the potential harm caused by compromising environmental due process with a project that may be found to violate NEPA. The court therefore enjoined the Defendants from the construction and renovation of the Williamsport warehouse for the purposes of operation as a detention and processing facility for the pendency of this lawsuit.  

As of June 2026, the case is ongoing; per status reports, the parties continue to confer on the installation of a security fence
