Whether an agency’s decision not to initiate investigative or enforcement proceedings is judicially reviewable under APA § 701(a)(2).
Holding
Generally no. An agency decision not to enforce is presumptively committed to agency discretion by law and therefore unreviewable under APA § 701(a)(2), unless Congress has supplied meaningful standards limiting that discretion.
Reasoning
The APA ordinarily permits review of final agency action, including a failure to act, but § 701(a)(2) excludes action “committed to agency discretion by law.” Under Citizens to Preserve Overton Park, this exception applies where a statute supplies no meaningful legal standard by which a court can judge the agency’s exercise of discretion.
The Court distinguished affirmative agency action from agency nonenforcement. In Overton Park, the agency had affirmatively approved a highway project under a statute containing concrete criteria. By contrast, a decision not to enforce ordinarily presents no comparable statutory benchmark for deciding which possible violations the agency must pursue.
Nonenforcement choices require agencies to balance matters particularly within their competence: whether a violation occurred, the likelihood of success, the agency’s overall enforcement policies, competing priorities, and limited resources. Agencies cannot pursue every technical violation, and courts are poorly positioned to reorder an agency’s enforcement priorities.
A refusal to enforce also resembles a prosecutor’s decision not to bring a case, an area traditionally entrusted to the Executive. Moreover, nonenforcement usually does not itself impose coercive burdens on a person’s liberty or property, while an actual enforcement action can later be reviewed for compliance with statutory limits.
The presumption is rebuttable. Congress may restrict enforcement discretion by establishing substantive priorities, mandatory duties, or otherwise meaningful standards. Dunlop v. Bachowski illustrated that point: the statute required the Secretary of Labor to investigate a union member’s complaint and to file suit upon specified findings, leaving a court standards against which to review the refusal.
