On his blog, Bill Schabas raises a fascinating issue regarding the territorial scope of application of the Rome Statute of the ICC:
On 11 March 2010, the United Kingdom informed the Secretary-General that it wished that its ratification of the Rome Statute of the International Criminal Court ‘be extended to the following territories for whose international relations the United Kingdom is responsible: Anguilla, Bermuda, British Virgin Islands, Cayman Islands, Falkland Islands, Montserrat, Pitcairn, Henderson, Ducie and Oeno Islands, St Helena, Ascension and Tristan da Cunha, Sovereign Base Areas of Akrotiri and Dhekelia, Turks and Caicos Islands’. The declaration added that the United Kingdom ‘considers the extension of the aforesaid Statute … to take effect from the date of deposit of this notification…’
The Argentine government then quite quickly objected to the UK declaration, because of their long-standing dispute over the Falklands/Malvinas. This has been the Argentine practice for quite some time (see, e..g, the similar UK and Argentine declarations with regard to the ICCPR (at the very end of the page)). But more interesting, as Bill notes, is the issue of the territorial scope of UK obligations:
Did the United Kingdom leave anything out of its declaration? What about Diego Garcia, which is part of the Chagos Archipelago in the British Indian Ocean Territory. After expelling the inhabitants of the islands, the British then essentially handed over the base to the United States, which uses it as a kind of a fixed aircraft carrier. Is the Diego Garcia military base subject to the Rome Statute because it forms part of the ‘territory’ of the United Kingdom? Or does the recent declaration attempt to confirm that it is not subject to the jurisdiction of the Court, because the United Kingdom has not made a declaration to that effect?
Aside from jurisdiction over territory, there is also the issue of responsibility for arrest and other cooperation obligations under the Rome Statute. By its declaration, was the United Kingdom suggesting that it was not previously responsible for cooperation with the Court with respect to the territories listed in the declaration?
The formulation of the UK’s declaration certainly indicated that hitherto it considered itself bound by the Rome Statute only with respect to its metropolitan territory. But was this indeed the case? Or did the UK have all of the Rome Statute obligations conditioned by territory with regard to, say, Bermuda, from the moment of ratification? And what of the territorial jurisdiction of the ICC?
Up until the end of its empire after the Second World War the UK had a rather stringent policy of including so-called colonial clauses in the multilateral treaties to which it was a party. Thus, for example, it had the negotiating power to have such clauses included in the ECHR and the Genocide Convention. The UK was motivated in this partially by a policy desire to avoid assuming burdensome obligations for territories in which it did not want to apply them, and partially by a constitutional convention that it needed the assent of its dependencies for the extension of treaties to them. The UK’s efforts were resisted, however, in respect of other treaties, such as the ICCPR. With regard to those treaties, the UK employed the practice of filing a declaration that would specify the territories to which the the treaty would apply – as with the ICCPR, and now the Rome Statute.
(For general background on all of this (and some fantastic scholarship), see Brian Simpson’s Human Rights and the End of Empire (OUP, 2004), as well as L. Moor and AWB Simpson, ‘Ghosts of Colonialism in the European Convention on Human Rights’, (2006) 76 BYBIL 121.)
Now, the big question is whether such declarations have any effect – and in particular, whether the UK’s declaration with regard to the Rome Statute has such an effect. What these declarations try to do is to avoid the application of Article 29 VCLT, which reads ‘unless a different intention appears from the treaty or is otherwise established, a treaty is binding upon each party in respect of its entire territory.’
As explained by the ILC in its Draft Articles on the Law of Treaties, the ‘entire territory’ bit encompasses all territories over which a state has title, and not just its metropolitan territory. Art. 29 thus creates a rebuttable presumption that a treaty applies to all of the territories that belong to a state party.
Now, Art. 29 doesn’t explicitly deal with declarations of territorial scope as those routinely used by the UK. The Draft Articles do say, however, that:
One Government [I imagine the UK, but I haven't checked] proposed that a second paragraph should be added to the article providing specifically that a State, which is composed of distinct autonomous parts, should have the right to declare to which of the constituent parts of the State a treaty is to apply. Under this proposal the declaration was not to be considered a reservation but a limitation of the consent to certain parts only of the State. The Commission was of the opinion that such a provision, however formulated, might raise as many problems as it would solve. It further considered that the words “unless a different intention appears from the treaty or is otherwise established” in the text now proposed give the necessary flexibility to the rule to cover all legitimate requirements in regard to the application of treaties to territory.
So what are then we to do with the UK’s declarations? First, it does not regard them as reservations, but as ‘limitations on its consent’ only to parts of its territory. But isn’t a reservation precisely a limitation on state consent? A mere interpretative declaration cannot as such have direct effect on state obligations, as this territorial declaration purports to. Second, Art. 120 of the Rome Statute explicitly forbids any reservations. Third, whatever their nature, they might reflect the UK’s intention, but they certainly do not reflect that of the other parties, which is the Art. 29 VCLT criterion. Finally, and quite oddly, unless I am mistaken from my quick skim of the UN treaty collection, the UK made the ICC declaration only some 12 years after it ratified the Statute. How can this affect the consent that it had already given? It is only if a general rule existed to the effect that states can vary the territorial scope of their obligations via declarations – but as we have seen the ILC was quite explicitly opposed to such a rule, and the instability it potentially brings seems very much undesirable, and unsupported by state practice.
Then again, Denmark also made a similar declaration with respect to the Faroe Islands and Greenland, which it later withdrew, as did the Netherlands. No state objected to such declarations in principle, which might be taken as a inference that they are permissible, and would thus serve to rebut the Art. 29 VCLT presumption. This is, in short, quite a vexing little problem – and one that I doubt the Court will ever have the opportunity to resolve.
