Key legal question
Whether the federal complaints against the cantonal decisions were admissible despite the political character of the school-closure decision.
Extracted holding
The complaints were admissible as direct appeals against a cantonal final decision with predominantly political character; however, the attacks on the municipal council decisions themselves were inadmissible because those decisions had been replaced by the cantonal rulings.
Extracted reasoning
The case fell under public law; the cantonal decisions were final in practice under Solothurn law, and Art. 86(3) BGG allowed direct appeal because the matter was predominantly political. The devolutive effect excluded separate challenge of the municipal decisions.
