Kernrechtsfrage
Whether the subsidiary constitutional complaint was admissible and the student had standing to challenge the non-promotion decision.
Extrahierter Entscheid
The complaint was admissible only as a subsidiary constitutional complaint, and standing existed only to invoke violations concerning the definitive admission criteria under § 9 PromotionsR/ZH; no standing existed regarding discretionary exceptional admission under § 13.
Extrahierte Begründung
The cantonal decision was a final decision not open to ordinary federal appeal. Because § 9 creates a legal entitlement when its conditions are met, the student could complain of arbitrariness as to that provision. By contrast, § 13 is a discretionary 'special case' clause and does not confer an enforceable right.
