Questão jurídica principal
Whether the federal appeal was admissible as an ordinary public-law appeal or only as a subsidiary constitutional complaint
Decisão extraída
The ordinary public-law appeal was excluded; the filing was treated as a subsidiary constitutional complaint, but only constitutional grievances expressly raised in the brief were examinable.
Fundamentação extraída
Because the dispute concerned a provisional licence withdrawal tied to a control-drive result, and the main matter itself was not open under Art. 83 lit. t BGG, only the subsidiary constitutional complaint was available. The challenged cantonal decisions were interlocutory, yet immediately reviewable due to irreparable harm.
