Contents

Place in the Framework

Per se illegality developed for restraints that courts view as so predictably anticompetitive that detailed market analysis is unnecessary.

Core Questions

  • What experience or judicial confidence justifies categorical treatment?
  • How do courts avoid extending per se rules to unfamiliar or integrated collaborations?
