United States v. New Jersey
Overview
Overview
The Trump administration challenged New Jersey Governor Mikie Sherrill's executive order which prevents federal immigration officer from using non-public areas of state owned property as operation bases to enforce civil immigration law.
The Issue
Issue
Whether New Jersey's executive order prohibiting federal immigration officers from using non-public areas of state-owned property as operational bases for civil immigration enforcement is preempted by federal law under the Supremacy Clause.
The Rules
Rule
Federal immigration enforcement authority derives from Congress's delegated power under the Immigration and Nationality Act. State laws and executive orders are preempted when they directly conflict with or obstruct the exercise of valid federal authority, though states retain sovereign control over state property.
The Application
Analysis
New Jersey's executive order restricts federal immigration officers' access to state property, potentially impeding federal civil immigration enforcement operations. The Trump administration contends this state action unconstitutionally obstructs federal authority; New Jersey asserts the executive order is a legitimate exercise of state control over state assets.
The Conclusion
Conclusion
The case remains active before Judge Georgette Castner in the District of New Jersey following its February 2026 filing, with no ruling yet issued on the preemption question.
