Questão jurídica principal
Whether the public-law appeal was admissible despite the subsidiary nature of the remedy and the foreign-law question involved.
Decisão extraída
The appeal was admissible as a public-law appeal against an incidental jurisdictional decision, and the foreign-law issue could be reviewed in that procedural posture.
Fundamentação extraída
The contested decision concerned competence; the complaints targeted constitutional and cantonal-procedure issues, and the Saudi-law question formed the core of the arbitration-exception dispute rather than a matter reserved to appeal in reform.
