Question juridique clé
Whether the complaint could rely on the alleged violation of the disposition principle and Art. 90(1)(b) OG.
Solution extraite
The complaint was not entered on in this respect because it attacked a factual/legal assessment rather than the parties' power to dispose of the dispute; such a challenge could only be raised by appeal.
Motifs extraits
The court held that the objection concerned the factual characterization of the parties' agreement, not the disposition principle itself, and was therefore outside the scope of state-law review.
