Whether Texas and Louisiana had Article III standing to challenge DHS's immigration-arrest priorities on the ground that federal non-enforcement would impose costs on the States.
Holding
No. The States lacked Article III standing because their asserted injury did not present the kind of dispute that federal courts traditionally may resolve by ordering the Executive Branch to make more arrests or initiate more enforcement actions.
Reasoning
Article III requires an injury in fact that is traceable to the defendant and redressable by judicial relief. Although monetary costs ordinarily qualify as injuries, the Court explained that an asserted injury must also be legally and judicially cognizable. History, tradition, and precedent help identify which disputes fit within the federal judicial power.
The States sought an order requiring DHS to change its arrest policy so that it would arrest more noncitizens. The Court found no historical practice or precedent supporting suits by parties who are neither prosecuted nor threatened with prosecution to compel the government to prosecute or arrest others. Instead, Linda R. S. v. Richard D. establishes that a private party ordinarily has no judicially cognizable interest in another person's prosecution, a principle that also applies to executive immigration enforcement.
The separation of powers reinforces that conclusion. Decisions about how aggressively to enforce the law, whom to arrest, and which cases to pursue are generally committed to the Executive under Article II. Immigration enforcement additionally implicates foreign-policy considerations, as well as ordinary public-safety judgments.
Courts also lack workable standards for evaluating whether the Executive has made enough arrests. The Executive never has sufficient resources to arrest, detain, remove, or prosecute every possible violator, and it must continually allocate finite resources as public-safety and public-welfare conditions change. All five administrations since the relevant immigration statutes took their present form had relied on enforcement priorities because of those limits.
The Court emphasized the narrowness of its ruling. A different standing analysis might arise in a selective-prosecution case, where Congress specifically authorizes defined injured plaintiffs to seek judicial enforcement, where the Executive wholly abandons statutory responsibilities, where non-enforcement is coupled with conferral of legal benefits or status, or where a policy concerns continued detention of people already arrested. None of those circumstances was presented here.
The Court did not decide whether the DHS guidelines actually complied with §§1226(c) and 1231(a)(2). It held only that federal courts were not the proper forum for these States to seek an order compelling additional arrests. Congress and voters retain political tools, including oversight, appropriations, legislation, confirmations, and elections, to influence enforcement policy.
