Questione giuridica chiave
Whether the public-law appeal was sufficiently reasoned to allow review of arbitrariness under Art. 9 of the Constitution.
Decisione estratta
The appeal did not contain a sufficient legal reasoning showing why the cantonal judgment was manifestly unsustainable; references to earlier submissions were inadmissible.
Motivazione estratta
In a public-law appeal the Federal Court examines only properly reasoned constitutional grievances. Bare references to other pleadings do not satisfy Art. 90 OG, and the appellant failed to substantiate arbitrariness.
