Substantiation: What a Claim Must Prove Before It Is Made

The rule is short. An advertiser must have the proof before the advertisement runs. The Federal Trade Commission treats an objective product claim as carrying an implied representation that the advertiser possessed a reasonable basis for it at the time of dissemination. Fail that, and the claim is deceptive whether or not it later turns out to be true.

The rule is prior, not eventual

Section 5 of the Federal Trade Commission Act, codified at 15 U.S.C. 45, prohibits unfair or deceptive acts or practices in or affecting commerce. Section 12, at 15 U.S.C. 52, adds a separate prohibition on disseminating a false advertisement for a food, drug, device, service or cosmetic. Neither section uses the word substantiation. The requirement comes from the Commission's reading that every objective claim implies the advertiser had support for it.

That timing point decides most disputes. A company that runs a durability claim and then commissions the testing has already made an unsupported claim, and the testing does not retroactively supply the basis. The practical consequence is that the substantiation file has to be closed and dated in the company's own records before the copy is released, and it has to cover the claim as consumers will read it rather than the claim as the copywriter intended it.

Materiality is assumed for most performance, price, safety and efficacy claims. The Commission's deception statement treats a claim as material where it is likely to affect a consumer's choice or conduct regarding the product. Express claims are presumed material. That presumption removes an element the advertiser might otherwise contest.

How much proof the claim demands

There is no single quantum. The Commission weighs the type of product, the consequence of a false claim, the benefit of a truthful claim, the cost of developing substantiation, and the amount of substantiation that experts in the field consider reasonable. A claim about the fit of a garment and a claim about a device that filters drinking water are not held to the same file.

Two categories recur. A general performance claim requires a reasonable basis: evidence sufficient to satisfy a person familiar with the field that the claim is true. A health, safety or efficacy claim requires competent and reliable scientific evidence, which the Commission describes as tests, analyses, research or studies conducted and evaluated in an objective manner by qualified persons, using procedures generally accepted in the profession to yield accurate and reliable results.

When the advertisement names its own evidence

An establishment claim is one that tells the consumer what proof exists. "Clinically proven," "laboratory tested to withstand," "studies show" and a cited head-to-head trial all fall inside it. Where the advertisement names the evidence, the advertiser must hold that evidence in the form named. A reasonable basis of some other kind will not do.

The distinction has a sharp edge. A non-establishment claim can sometimes be supported by a body of evidence considered as a whole, including surveillance data and accepted professional consensus. An establishment claim referring to clinical testing must be supported by clinical testing on the advertised product, and a claim referring to two studies must be supported by two. The same discipline runs through nutrient content and health claims on labels, where the permitted wording is fixed in advance and the evidence standard is set by rule rather than by the advertiser.

What the substantiation file holds

A usable file names the claim, in the exact words that will appear, and pairs it with the document that supports it. Test reports should identify the method, the sample size, the operator and the conditions. Where a survey supports a claim, the questionnaire and the sampling frame belong in the file, because a leading question destroys the result. Where a third party performed the work, the engagement terms and the laboratory's accreditation belong there too.

Files decay. A claim that was supported when the product launched may be unsupported after a component change, a formulation change or a supplier change, and the advertisement usually keeps running. Assign the file to a named owner, and tie its review to the engineering change process rather than to a marketing calendar. The same reasoning governs how the net impression of an advertisement is fixed, which is the subject of express and implied claims and the net impression.

Records held for other regulators frequently do the work. A carrier advertising transit performance can draw on the operating and safety records it already keeps, and a company advertising service coverage through intermediaries should hold the contracts, in the way described under broker bonding and double brokering duties. A food company's specification records support both a label and an advertisement, as with the identity, net quantity and ingredient rules on a food label.

The consequence of running unsupported

The Commission may proceed administratively toward a cease and desist order, or in federal court. Civil penalties attach where a respondent violates a final order or, under 15 U.S.C. 45(m), where a party acted with actual knowledge that a practice was unfair or deceptive as determined in a prior Commission order. Monetary relief for consumers is pursued under the authorities the Commission has available, and orders routinely impose recordkeeping and compliance reporting for years.

Orders also travel. A negotiated order commonly binds the individual officers named in it, covers products beyond the one at issue, and requires the respondent to hold substantiation of a specified type for any future claim in the covered category. That fencing-in provision converts a general legal standard into a specific contractual duty, and the penalty for breaching it is calculated per violation.

The state route runs alongside. Every state has a statute prohibiting deceptive trade practices, most of them enforced by the attorney general and many of them permitting private suit with fee shifting. A single national campaign can therefore draw federal, state and competitor challenges from the same set of facts, each with its own standard of proof.
