Question juridique clé
Whether the appeal against the arbitral rectification addendum is admissible
Solution extraite
The appeal was formally admissible as to timeliness and standing, but all substantive grievances were inadmissible because they targeted the original award or lacked proper reasoning.
Motifs extraits
A rectification addendum is accessory to the original award and may be challenged only for defects relating to the rectification itself, not to reopen issues already covered by the original award.
