What are the facts?
The Association of Data Processing Service Organizations (ADAPSO), representing companies that sold data-processing services, challenged a ruling by the Comptroller of the Currency (William B. Camp) that permitted national banks to provide data-processing services to other banks and to nonbank customers as incidental to the "business of banking." ADAPSO alleged that the ruling would subject its members to direct economic harm by authorizing national banks—powerful potential competitors—to enter the data-processing market. Substantively, ADAPSO contended that the Comptroller's ruling exceeded statutory limits: (1) the National Bank Act, 12 U.S.C. § 24 (Seventh), which confines national banks to the "business of banking" and its incidental powers, and (2) the Bank Service Corporation Act (BSCA), particularly § 4, 12 U.S.C. § 1864, which they read as restricting the scope of bank-related service activities and barring the provision of nonbanking services to the general public. ADAPSO sought declaratory and injunctive relief under the APA, § 10, claiming that the Comptroller's ruling was unlawful. The lower courts dismissed the suit for lack of standing, reasoning that ADAPSO and its members lacked a legally protected interest sufficient to challenge the ruling. The Supreme Court granted certiorari.
What is the legal issue?
Do competitors of national banks have standing under § 10 of the Administrative Procedure Act to challenge the Comptroller of the Currency's ruling permitting national banks to offer data-processing services to nonbank customers, based on alleged economic injury and statutory limits on bank activities?
What rule applies?
Under § 10 of the Administrative Procedure Act (5 U.S.C. § 702), a person is entitled to judicial review if they are (1) suffering injury in fact—economic or otherwise—and (2) their interests are arguably within the zone of interests to be protected or regulated by the statute underlying the agency action. The older "legal interest" test is not the proper standard for standing; the question is not whether the plaintiff will prevail on the merits, but whether the plaintiff is an appropriate party to invoke judicial review of the challenged action.
What did the court hold?
Yes. ADAPSO's members alleged injury in fact from increased competition, and their interests are arguably within the zone of interests protected or regulated by the National Bank Act and the Bank Service Corporation Act. Accordingly, they have standing under the APA to seek review of the Comptroller's ruling.
What is the reasoning?
The Court, per Justice Douglas, reframed the standing inquiry in APA cases. First, it recognized that economic injury—such as the competitive harm alleged by ADAPSO—constitutes a concrete injury in fact sufficient to satisfy Article III. The plaintiffs plausibly alleged that the Comptroller's ruling would permit national banks to enter their market and divert business, a real-world, non-speculative injury traceable to the agency action and remediable by its invalidation. Second, turning to the statutory dimension of APA standing, the Court explained that § 10 of the APA grants review to a person "adversely affected or aggrieved within the meaning of a relevant statute." This means courts must ask whether the plaintiff's interests are at least arguably within the "zone of interests" that the relevant statutes seek to protect or regulate. Here, the National Bank Act's limitation of national banks to the "business of banking" and the BSCA's restrictions on bank service corporations indicate a congressional concern with confining bank activities and preventing certain encroachments into nonbanking domains. Although these statutes do not expressly create a right in data-processing companies, the constraints they impose on banks arguably encompass the competitive interests of entities facing bank encroachment. Third, the Court rejected the prior "legal interest" test, which had asked whether the plaintiff possessed a substantive legal right that the agency action invaded. That test collapsed standing into the merits. Instead, the proper standing analysis separates threshold justiciability from ultimate merits: even if the plaintiffs ultimately lose on whether the statutes prohibit the Comptroller's ruling, they can still be proper parties to bring the challenge. The Court therefore concluded that ADAPSO satisfied both injury in fact and the zone-of-interests requirement and could proceed to litigate the lawfulness of the Comptroller's action. The case was remanded for consideration of the merits.
Why is this case significant?
Data Processing marks the modern starting point for standing in APA cases. It establishes that competitor economic injury is a cognizable injury in fact and introduces the influential zone-of-interests test, significantly broadening who may challenge agency action. For law students, it is essential both doctrinally and methodologically: it clarifies the separation between standing and merits, shows how statutory purposes shape who can sue, and sets the stage for later refinements (e.g., Lujan's traceability/redressability and Lexmark's reclassification of the zone-of-interests inquiry as a matter of statutory cause-of-action scope rather than purely prudential standing). The case is also a staple in understanding judicial review of agency action and the role of competitors in enforcing statutory limits on regulated entities.
What specific statutes did the plaintiffs rely on to challenge the Comptroller's ruling?
They relied on two: (1) the National Bank Act, 12 U.S.C. § 24 (Seventh), which restricts national banks to the "business of banking" and its incidental powers, and (2) the Bank Service Corporation Act (BSCA), particularly § 4, 12 U.S.C. § 1864, which limits the business activities of bank service corporations and reflects Congress's concern with preventing banks from engaging in nonbanking services for the general public. Plaintiffs argued the Comptroller's ruling exceeded these statutory limits.
Did the Supreme Court decide whether national banks may lawfully provide data-processing services to nonbank customers?
No. The Court addressed only standing. It held that plaintiffs could proceed with their challenge under the APA, then remanded for the lower courts to consider the merits—i.e., whether the Comptroller's ruling actually violated the National Bank Act or the BSCA.
How did the case change the law of standing?
It rejected the restrictive "legal interest" test and established that (1) a concrete injury in fact—economic or otherwise—is sufficient for Article III, and (2) plaintiffs must show their interests are arguably within the zone of interests the relevant statute protects or regulates. This two-part framework broadened access to judicial review of agency action, especially for competitors.
What is competitor standing, and how does this case support it?
Competitor standing recognizes that parties may be injured when the government unlawfully authorizes competitors to enter a market or grants them advantages, causing economic harm. Data Processing confirms that such economic harm is an injury in fact, enabling competitors to challenge agency actions that allegedly violate statutory constraints.
How does Data Processing relate to later cases like Lujan and Lexmark?
Data Processing contributed the injury-in-fact and zone-of-interests concepts. Lujan v. Defenders of Wildlife later refined Article III standing by emphasizing injury in fact, causation, and redressability. Lexmark International v. Static Control clarified that the zone-of-interests inquiry is fundamentally a matter of statutory interpretation—who has a cause of action under the statute—rather than a purely prudential bar. Still, Data Processing's articulation remains a touchstone in APA standing analyses.
Does the zone-of-interests test require that the statute expressly protect the plaintiff?
No. The test is generous: the plaintiff's interests need only be arguably within the statute's protective or regulatory ambit. Direct conferral of rights is unnecessary; what matters is whether the statute's purpose and constraints plausibly encompass the plaintiff's interests. Data Processing applied this approach to conclude that limits on bank activities arguably encompass competitors affected by unlawful bank entry into nonbanking markets.
