Under the Consumer Protection (Fair Trading) Act, it is an unfair practice for a retailer to make false or misleading claims.
Likewise, one of the general principles of the Singapore Code of Advertising Practice is that of truthful presentation.
From SCAP: II. General Principles 5. Truthful presentation:
5.1 Advertisements should not mislead in any way by inaccuracy, ambiguity, exaggeration, omission or otherwise. More specifically, advertisements should not:
- Misrepresent any matter likely to influence consumers’ attitude to any product, advertiser, or promoter;
- Misrepresent any information to mislead consumers into believing any matter that is not true, such as the source of the product, quality of the product, obligation (or non-obligation) in using a trial product, and others;
- Mislead consumers about the price of goods or services;
- Underestimate the actual total price to be paid;
- Mislead consumers to overestimate the value or mislead consumers regarding the conditions on the terms of payment such as hire purchase, leasing, instalment sales and credit sales; or
- Mislead consumers regarding the terms or guarantee, delivery, exchange, return, repair and maintenance; and mislead consumers regarding the extent of benefits for charitable causes.
5.2 If a presentation (such as a speech, documentary and newsreel) is substantially an advertisement, it should be clearly stated as an advertisement.
- Advertisements should not misuse research results or quotations from technical and scientific publications.
- Statistics should not be so presented so as to imply a greater validity that they really have.
- Scientific terms should not be misused; scientific jargon and irrelevancies should not be used to make claims appear to have any scientific basis which they do not possess.
