Questão jurídica principal
Whether the public-law appeal against recognition of party-plaintiff status was admissible immediately.
Decisão extraída
No. The contested cantonal decision was incidental and caused no irreparable legal harm; it could only be challenged together with the final decision.
Fundamentação extraída
A decision granting a third party party-plaintiff status is incident and, under Article 87 OJ, is not separately appealable absent irreparable legal damage. The appellant showed no special circumstance justifying immediate review.
