Case Summary

Amidst the increased immigration enforcement actions, the State of New Jersey, at the direction of Governor Mikie Sherill barred federal immigration officers from “entering, accessing, or using nonpublic areas” of state-owned property to enforce civil immigration law, and prohibiting federal immigration officers from using state-owned property as a “staging area, processing location, or operations base” to enforce civil immigration law. New Jersey executive branch departments and agencies were …

Amidst the increased immigration enforcement actions, the State of New Jersey, at the direction of Governor Mikie Sherill barred federal immigration officers from “entering, accessing, or using nonpublic areas” of state-owned property to enforce civil immigration law, and prohibiting federal immigration officers from using state-owned property as a “staging area, processing location, or operations base” to enforce civil immigration law. New Jersey executive branch departments and agencies were instructed not to permit to 'or consent to federal immigration officers entering, accessing, or using nonpublic areas of State property for the purpose of facilitating federal enforcement of civil immigration law.”

In response, the United States government brought this suit in the District of New Jersey, alleging that the New Jersey order obstructs immigration enforcement in violation of the Supremacy Clause. They further alleged the order constitutes unlawful discrimination against and regulation of the federal government in violation of the doctrine of Intergovernmental Immunity. The government requested a declaration that the New Jersey order is invalid and a permanent injunction prohibiting New Jersey from enforcing the order. The case has been assigned to Judge Georgette Castner.

This case is ongoing.
