Having its roots in the public international law field of “diplomatic protection”,1 yet not forming part of customary international law,2 the doctrine of “genuine and effective link” pertains to a test of genuine connection and closeness between a legal or natural person and its home State, in order for such person to be able to invoke the nationality of that State.
In investment treaty law, the “genuine and effective link” doctrine has not been directly discussed in the context of jurisdiction ratione materiae, but it can conceivably be linked to the issue of ownership and control in International Investment Agreements (“IIAs”), and may be relevant in determining whether there exists a required link between an investment and an investor.
II. Permutations of the "genuine and effective" link doctrine in other issues
A. Jurisdiction ratione personae
In international investment law, direct reference to this doctrine has only been made in the context of jurisdiction ratione personae, with respondent States objecting to purported investors invoking the nationality of a State with which they have no actual connection.3 Investment tribunals have so far unanimously rejected such contentions.4
B. Law of the sea
In the context of the United Nations Convention on the Law of the Sea (“UNCLOS”), a variation of this doctrine is used to establish the nationality of ships, in that “[t]here must exist a genuine link between the State and the ship”.5
III. Genuine and effective link between investment and investor
To qualify as a “protected investment”, a putative investment must be linked to a qualifying investor, namely, an investor that satisfies the ratione personae jurisdictional requirements of a particular IIA.6 In other words, an investment must be genuinely and effectively linked to an investor, and, by extension, to that investor’s home State.
IV. Treaty practice
Certain IIAs contain specific wording to that effect, by defining “investments” as those that are “owned or controlled, directly or indirectly” by a qualifying investor.7 Only a few of those clarify the meaning of ownership or control.8 The majority of older IIAs are silent on the type of link required.9
V. Indirect investment
While, in principle, investments can be structured through several corporate layers of subsidiaries and other affiliates (“indirect investment”), for the purposes of establishing a genuine and effective link between the investment and the investor, ownership or control must be established in each layer.10 Investment claims with only a “remote connection to the affected company” must be cut off in the sense that they do not comport with the host State’s consent to arbitration.11
VI. Portfolio investment
With seemingly only two exceptions12 — and save for contrary treaty language13 — investment tribunals generally consider that holding shares in a company without holding a stake for management purposes (“portfolio investment”) is a legitimate “investment” activity;14 and, by extension, that it constitutes a “genuine and effective link” between an investment and an investor.
