Sovereign Preemption State Standing

Abstract

When does a state have standing to challenge the executive branch’s alleged under-enforcement of federal law? The issue took on importance during the Obama administration, with “red states” suing the executive branch over numerous issues, including immigration and health care. The question of standing looks to remain critical during the Trump administration, only with the political orientation of the actors reversed. This Article argues in favor of sovereign preemption standing, under which a state would enjoy Article III standing to sue the federal government when (i) the federal government preempts state law, yet (ii) the executive branch allegedly under-enforces the federal law that Congress enacted to fill the regulatory gap to which the preemption gave rise. Sovereign preemption state standing arises naturally out of the function of states in the federal system. It is grounded upon parens patriae injury — that is, injury to the state’s ability to protect its citizens against harm. The federal government can properly preempt state law, on the logic that it then assumes from the state the obligation to protect the state’s citizens from harm. Where the executive branch then fails adequately to enforce federal law, it leaves the state’s citizens unprotected. The state then has Article III standing to sue the federal government on behalf of its citizenry.The universe of cases where sovereign preemption state standing operates is not large, which should assuage concerns over opening the floodgates of state-federal litigation. Moreover, prudential doctrines can be overlaid such that more cases would be screened out. Alternatively, sovereign preemption state standing also can be construed somewhat more broadly so that it applies not only to the setting of executive branch under-enforcement, but to the setting of horizontal federal disagreement in general — i.e., to the setting of executive branch over-enforcement as well.
