Standing to sue

Why can a court refuse to rule on a plain injustice because the person raising it was not the one harmed?

An agency is plainly ignoring the statute that governs it. A citizen who has read the statute and can prove the breach brings the case. The court dismisses it without reaching the merits: you are not the right person to ask. Nothing in that outcome touches whether the breach occurred.

It looks like evasion dressed as procedure, and sometimes it is. But before accepting that, notice what a court actually is. It has no inspectors and no research staff, it cannot go looking for cases, and it learns only what two opposed parties choose to place before it. Given that machine, the question changes shape. It is no longer "is this injustice real?" but "does this claimant supply what the machine needs in order to decide well — and what entitles a court to decide it at all?"

Take the first half. Adversarial fact-finding has one engine: two parties who each want to win. Everything the court will ever know arrives because someone had a reason to dig it up, and every weak argument is exposed because someone had a reason to attack it. An injured claimant supplies that engine; a claimant who merely disapproves supplies an interest in the question, which produces a thinner record and a softer fight. Injury also converts an abstraction into facts. "The agency is misreading the statute" can be argued forever; "the misreading closed my road, and here is what followed" gives a court something concrete to rule on, and confines the ruling to what those facts require.

Now the second half, usually left out. A court's ruling does not stay with the parties — it becomes precedent, binding people who were never in the room. So a rule about who may sue is also a rule about who may set law for everyone. Open the door to anyone and the governing reading of a statute is fixed by whoever files first, typically the most motivated organisation, on the facts most convenient to it, possibly on a dispute constructed for the purpose. Requiring a real injury lets the question mature until a case arrives that puts it in its true form.

There is a constitutional layer as well. A complaint that "the government is not following the law", felt equally by every citizen, is not a dispute between parties; it is a grievance about governance, and routing such grievances through courts hands the judiciary a general supervisory power over the elected branches. American doctrine builds this in explicitly: the constitution grants federal courts only "cases" and "controversies", and the modern three-part test — a concrete and particularised injury in fact, traceable to the defendant, redressable by the relief sought — was set out in that form in Lujan v. Defenders of Wildlife in 1992. Whether so strict a version is required, or is largely a twentieth-century construction, is genuinely argued among scholars.

Then follow the consequence honestly, because it is severe. The doctrine sorts by how concentrated a harm is, not how large. A harm falling on one person is litigable; the same harm spread thinly over sixty million may be enormous in total and unactionable in every instance. That is why diffuse environmental damage and mass surveillance are hardest to bring: in Clapper v. Amnesty International in 2013, plaintiffs challenging a surveillance programme were turned away for failing to show they had actually been monitored — a fact the programme's secrecy prevented them from knowing. The doctrine's virtue and its worst failure are one feature seen from two sides.

Notice what legal systems then do about that. They invent standing where diffusion would otherwise silence a real harm: class actions aggregate small injuries into a large one, statutes write in citizen-suit provisions, relator actions let a private party sue on the state's behalf, attorneys general sue for their residents. England takes a looser route, asking only whether an applicant has a "sufficient interest", which admits public-interest challenges directly. The requirement is real, but it is treated as a design parameter rather than a law of nature.

Standing is not a judgement that the claim is weak, and a dismissal for want of standing decides nothing about the merits — the same claim can be brought by a properly injured plaintiff the next day and win.

Nor does the requirement track who is most affected. Courts routinely accept plaintiffs with trivial injuries — a few dollars, an aesthetic interest in a river — because the injury is doing a structural job, not a moral one: guaranteeing a real dispute, a concrete record and a motivated opponent. A small genuine injury does that; a large sense of outrage does not.

It is worth separating this from two nearby ideas in this collection. The separation of powers asks how authority is divided between branches; standing is one of the valves by which a judiciary limits its own jurisdiction, which is why courts enforce it against themselves. And the puzzle of imperceptible harms is moral — whether an undetectable contribution can be wrong at all; standing is procedural and concedes the wrong entirely, asking only who may bring it. The two meet in a bleak place: harms too diffuse to perceive are usually also too diffuse to sue over.

• How class actions convert many unlitigable injuries into one litigable claim, and what they lose in doing so.
• Why third-party standing is occasionally allowed — a doctor asserting a patient's rights — and what the exception reveals about the rule.
