Literal falsity refers to a statement that is outright false and not subject to interpretation, meaning it can be easily proven wrong. In the context of advertising claims, when a statement is literally false, it does not accurately reflect the product or service being advertised, making it a key aspect in determining false advertising under relevant laws. Establishing literal falsity is essential for bringing forward a legal claim regarding deceptive practices, as it indicates that the advertisement misleads consumers in a clear and direct manner.
