Questione giuridica chiave
Whether the public-law constitutional appeal against the cantonal regulation was admissible.
Decisione estratta
The appeal was admissible insofar as the contested norm directly regulated the appellants' legal position and no cantonal abstract review remedy existed.
Motivazione estratta
The regulation was a general cantonal norm affecting the appellants' employment relations; the appellants had standing as potentially affected teachers; the appeal was timely; the main prayer to annul the entire regulation was insufficiently reasoned and therefore inadmissible.
