Legal Analysis of Executive Authority Over Immigration Enforcement Priorities

This opinion examines the scope of executive authority to establish immigration enforcement priorities, including the legal basis for prosecutorial discretion in removal proceedings. It analyzes the Take Care Clause, the Immigration and Nationality Act's provisions on removal, and relevant Supreme Court precedent including Arizona v. United States.

The opinion discusses the distinction between setting enforcement priorities and categorically declining to enforce statutory mandates, analyzing the legal boundaries of executive discretion. It reviews the history of enforcement priority memoranda from prior administrations and their judicial treatment.

The opinion concludes that the executive has broad but not unlimited discretion to establish enforcement priorities, provided those priorities do not amount to an abdication of the statutory duty to enforce immigration law. It recommends specific criteria for establishing defensible enforcement priority categories.
