Questione giuridica chiave
Whether the public-law appeal was sufficiently reasoned under Art. 90 al. 1 let. b OJ.
Decisione estratta
The appeal met the minimum reasoning requirements because the challenged interpretation, if arbitrary, would necessarily make the result arbitrary as well.
Motivazione estratta
The complaint targeted the cantonal court's interpretation of the admissibility provision; if that interpretation were unsustainable, the appellant would be wholly deprived of review of the costs ruling, which suffices for the arbitrariness attack.
