Questão jurídica principal
Whether the arbitral tribunal had jurisdiction despite the respondent's temporary deregistration and later re-registration.
Decisão extraída
The tribunal's jurisdiction was upheld; under the applicable foreign law, re-registration retroactively restored the respondent's legal capacity throughout the period of deregistration.
Fundamentação extraída
The Court held that the foreign law governed the respondent's capacity to be a party. Because the re-registration had retroactive effect, the respondent was deemed never to have ceased to exist. The appellant's reliance on Swiss procedural timing rules was irrelevant, and the attack based on alleged abuse of rights lacked factual support.
