Perhaps the most important comes from Section 13 (1) (a) of the Consumer Protection Regulations.
This says that “any supplier who offers a commodity or service to a consumer fails to meet minimum standards and specifications if … the commodity sold … is not of merchantable quality”. “Merchantable quality” is defined in the Regulations as “fit for the purposes for which commodities of that kind are usually purchased, as it is reasonable to expect in light of the relevant circumstances”.
