It is prohibited for a group of competitors to agree to refuse to do business with one or more customers or suppliers to the extent that it would disrupt the latter from conducting business in a market.
For example, the following agreements between competitors are prohibited:
- Not to supply to certain customers;
- Not to purchase from certain suppliers;
- To make the supply or purchase of goods subject to certain mutually agreed conditions.
Instructions to a supplier or customer to behave in these ways is equally prohibited if such instructions are coordinated with competitors.
