Militating perhaps even more strongly in favor of a stay
are “considerations of comity,” which “are particularly resonant here, given
that resolving this case mandates addressing a conflict between decades-old treaties and newly
minted EU case law.”
Id. at 40. As discussed above, this Court would
need to come down on one side or the other of an extremely high-stakes war of interpretation between
the EU and several of its member states on one side and several ICSID tribunals and investors on the
other. Indeed, as Spain points out, there is yet another open front in this conflict: there are
currently three cases pending before the CJEU which raise the question whether
Achmea’s reasoning applies to arbitration initiated under Article 26 of
the ECT. Def.’s Reply at 11; Hindelang Decl. ¶ 13. As mentioned above, ICSID may not view
the ultimate decision of the CJEU as binding on its arbitral jurisdiction, but the CJEU’s
decision may provide further persuasive authority to guide this Court’s eventual resolution of
these sensitive international questions.
4 Meanwhile, there are at least six other actions to enforce
arbitral awards against Spain currently pending in this District, and it is no coincidence that all
of them have been stayed pending resolution of annulment proceedings.
