Though in general, each business may decide with whom they wish to transact, there are some situations when a refusal to deal may be considered an unlawful anti-competitive practice, if it prevents or reduces competition in a market. The unlawful behaviour may involve two or more companies refusing to use, buy from or otherwise deal with a person or business, such as a competitor, for the purpose of inflicting some economic loss on the target or otherwise force them out of the market. A refusal to deal (also known as a group boycott) is forbidden in some countries which have restricted market economies, though the actual acts or situations which may constitute such unacceptable behaviour may vary significantly between jurisdictions.
