THE COURTS

Certification Is the Case

Whether a thousand claims proceed as one is decided before any of them is examined, and the decision usually ends the matter either way.

Ruth Okonkwo covers the federal courts and the litigation that shapes them. She follows cases from the first complaint rather than from the ruling.

A claim too small to bring alone is not a claim anybody brings. If the loss is forty dollars, no lawyer takes it and no person pursues it, whatever the merits.

The aggregation device exists to solve that, by allowing many identical small claims to be tried once, and it is the only mechanism that makes such wrongs reachable at all.

The rulemaking authority under which the procedure was written contains an instruction that has quietly done most of the work in this area for decades.

Rules of procedure may not abridge, enlarge or modify any substantive right, which sounds like a technical boundary and is in fact the central battleground.

Because a procedure that determines whether a claim can be brought at all is doing something very hard to distinguish from determining whether the right exists.

The opt-out structure is the feature that makes the whole thing constitutionally interesting and is barely discussed outside the specialist literature.

Certification is the moment this becomes concrete. Before it, there is a proposed group; after it, either a single case worth defending seriously or a handful of claims worth nothing.

A person is in the group unless they take a step to leave it, and taking that step requires knowing the case exists and understanding what leaving costs.

The decision therefore ends most disputes in one direction or the other, which is why it attracts far more litigation effort than the underlying conduct ever does.

Almost nobody does either, so membership is determined in practice by inertia, and the judgment binds people whose only participation was failing to act.

A denied certification is rarely appealed to a conclusion, because the individual claims that remain cannot justify the cost of appealing.

A granted certification is rarely tried, because the aggregate exposure makes trial an unacceptable risk for the defendant regardless of the merits.

So the procedure produces very few judgments about whether the conduct was lawful, which is the thing everybody assumes litigation is for.

The published opinions bear this out. The body of law is overwhelmingly about the requirements for certification rather than about the wrongs alleged.

Commonality is the requirement doing the most work, and it asks whether the members' claims share a question capable of being answered once for everyone.

That is a real requirement with an obvious rationale, and it is also the point at which a defendant argues that every claimant's circumstances differ.

They always do differ, in some respect. The question is whether the differences matter, and reasonable judges answer it differently on similar facts.

The caseload figures show these proceedings as a small share of filings and a disproportionate share of judicial attention, which is what you would expect.

The settlement dynamic is where the criticism has most force, and the criticism is largely fair.

A settlement resolving thousands of claims is negotiated by lawyers on both sides, approved by a judge, and accepted by claimants who mostly never learn it happened.

Recovery per person is frequently trivial while fees are substantial, and defending that arrangement on the basis that the claimants would otherwise have received nothing is true and unsatisfying.

The response that the point is deterrence rather than compensation is more honest, and it concedes that the mechanism is a regulatory instrument wearing the clothes of private litigation.

The description of what the federal courts handle places all of this within ordinary civil jurisdiction, which understates how unlike ordinary litigation it is.

An ordinary case is a dispute between parties who chose to be there. This is a proceeding that binds thousands of people who were never asked and mostly never told.

Notice requirements exist to address that and work poorly, because a notice reaching someone about a forty dollar claim is a notice they have no reason to read.

None of which is an argument against the device. Without it, an entire category of conduct becomes effectively lawful because no individual injury is worth pursuing.

It is an argument for candour about what the procedure is: a way of enforcing standards when the alternative is no enforcement, decided at a stage before anyone examines the standard.
