False Advertisement Law and Legal Definition
The term false advertisement means “an advertisement, other than labeling, which is misleading in a material respect; and in determining whether any advertisement is misleading, there shall be taken into account (among other things) not only representations made or suggested by statement, word, design, device, sound, or any combination thereof, but also the extent to which the advertisement fails to reveal facts material in the light of such representations or material with respect to consequences which may result from the use of the commodity to which the advertisement relates under the conditions prescribed in said advertisement, or under such conditions as are customary or usual.
No advertisement of a drug shall be deemed to be false if it is disseminated only to members of the medical profession, contains no false representation of a material fact, and includes, or is accompanied in each instance by truthful disclosure of, the formula showing quantitatively each ingredient of such drug.
In the case of oleomargarine or margarine an advertisement shall be deemed misleading in a material respect if in such advertisement representations are made or suggested by statement, word, grade designation, design, device, symbol, sound, or any combination thereof, that such oleomargarine or margarine is a dairy product, except that nothing contained herein shall prevent a truthful, accurate, and full statement in any such advertisement of all the ingredients contained in such oleomargarine or margarine.” (15 USCS § 55)
