Questione giuridica chiave
Whether the late-filed cantonal appeal period should be reinstated
Decisione estratta
Reinstatement was denied because the late filing resulted from a law office error or staff overload, which is not an excusable impediment.
Motivazione estratta
Time limits serve orderly administration of justice; reinstatement is available only for an unexcused inability to act in time. The failure was attributable to counsel or his staff, not to an unavoidable hindrance.
