Costs of arbitration / Apportionment / Apportionment of fees of expert appointed by the Arbitral Tribunal

'The Arbitral Tribunal considers that Claimant N° 2 fails in all his claims.

The Arbitral Tribunal considers that while those of Claimant company N° 1 are all allowed in principle, this company, to a large extent, fails as regards their quantum.

The Arbitral Tribunal therefore estimates that all arbitration costs, other than those of the expert, should be shared fifty-fifty.

Such an apportionment is however unwarranted for the fees and costs resulting from the intervention of [the expert appointed by the Arbitral Tribunal].

Indeed Defendant fails in principle under all headings of the claims submitted by Claimant No. 1, and the expert's intervention was only made necessary by the means of defense adopted by Defendant.'
