Advertising Claims Substantiation

3. Types of Claims Requiring Substantiation

A. Burden of Proof

The advertiser, not the consumer, must prove the claim is true.

B. Evidence Must Pre-Exist

Substantiation must exist before publication, not created after complaint.

C. Claims Interpreted from Consumer Perspective

Courts assess how an average consumer understands the claim.

D. Puffery vs Factual Claim

Puffery (“world’s tastiest”) → allowed

Objective measurable claim (“reduces cholesterol by 30%”) → requires proof

Small print cannot correct a misleading main message.

5. Consequences of Non-Substantiation

Advertisement withdrawal orders

Monetary penalties

Product recall (in serious cases)
