Effects Doctrine
A doctrine, developed mainly by the American courts in anti-trust cases, asserting jurisdiction over acts of foreign nationals committed abroad but having effects in the American marketplace; an extended form of the objective territorial principle. Source: Irwin Law The effects doctrine is a principle enabling a forum to assert jurisdiction over parties not present within a state but whose conduct outside the state’s territory affects the local market. The effects doctrine is frequently mistakenly equated with extraterritoriality. However, extraterritoriality is a wider concept. It also includes situations when part of the conduct in question occurred within its territory or when piercing of the corporate veil enables to assert jurisdiction over a foreign parent due to the local presence of a subsidiary.
