As to the second objection (
ratione
materiae, investment), the Respondent submits that this objection can be decided on the basis
of the Claimants’ arguments submitted in their Memorial on Jurisdiction alone, that it concerns
questions which can be decided before the merits stage, and that it only requires a very basic
examination of the facts already presented and a taking of evidence is not necessary.
20 The Claimants, again, state
that it “is so intertwined with the merits that it would not be efficient or fair to
bifurcate”.
21 The Claimants
argue that examination of experts and witnesses would be needed, and that the Respondent has made
references to some paragraphs of the Claimants’ expert reports and witness statements.
22 Nonetheless, even under the
assumption that hypothetical efficiency could prevail over the preferential character of jurisdictional
objections –
quod non, on the basis of the record as it currently stands,
the Claimants’ statements are not persuasive in this regard. The very few referred paragraphs seem
to be mentioned just as support (not to rebate them) by the referring Party and, without entering into
undue speculation, the fact is that, having both the Respondent and the Claimants already submitted the
first round of pleadings on jurisdiction: (i) the Respondent’s Memorial on Jurisdiction
is not accompanied by any expert reports or witness
statements; and (ii) the Claimants’ Memorial on Jurisdiction
is not
accompanied either by any additional expert reports or witness statements.
