This publication addresses the question of extraterritoriality (extraterritorial jurisdiction) in the area of competition law. It examines whether or not domestic competition legislation applies to foreign entities that may not be present in the forum, but whose conduct harms or may harm local consumers or producers. It also analyzes existing enforcement track record and hurdles involved in such cases. Transnational conduct can take the form of price-fixing among foreign producers, an abuse of dominant position, or a merger between foreign firms.
