The term “boycotting” refers to the conduct of a business making or establishing agreements with other businesses not to do transactions with a certain enterprise in order to achieve the purpose of hurting such a certain enterprise or depriving such a certain enterprise of its capacity to participate in market activities in the future. Such conduct is subject to the regulation against practices “causing another enterprise to discontinue supply, purchase or other business transactions with a particular enterprise for the purpose of injuring such particular enterprise” prescribed in Subparagraph 1 of Article 20 of the Fair Trade Act. In general, each business may act according to it own profit considerations and decide to refuse transactions with any other enterprise. However, when a business is boycotted by other businesses and rendered unable to compete with other businesses, the intrinsic nature of competition is twisted. Therefore, boycotting is subject to the Fair Trade Act.
