What is a Horizontal Restraint of Trade?
While there are several established types of horizontal restraint, any situation that meets the following elements may be illegal.
- Agreement - Was there an agreement between or among market participants?
-
Restraint- Was there an identifiable restraint of trade? If so, was the restraint:
- Naked with no pro-competitive justification? If so, it is per se illegal.
- Naked with a pro-competitive justification? Then apply the quick-look rule of reason.
- Not a naked restraint? Then the rule of reason applies.
Remember, there is no requirement that a business have extensive market power for conduct to be illegal under 1.
