This document discusses issues related to extraterritorial remedies in competition law. It notes the tension between a competition agency's mandate to protect domestic consumers and implications for foreign sovereign interests when imposing remedies with extraterritorial effect. The document proposes several principles for use of extraterritorial remedies, including that they only be used in exceptional circumstances when substantial domestic harm cannot otherwise be remedied, jurisdictional preconditions are met, remedies are no broader than necessary, and comity considerations are taken into account.
