Questione giuridica chiave
Whether the state-law appeal was admissible without exhausting the cantonal remedies available against the guardianship decision.
Decisione estratta
The appeal was inadmissible because a further cantonal complaint to the Kleiner Rat of Graubünden was still available and could also have raised the alleged federal-law violation.
Motivazione estratta
For complaints alleging violation of federal rules on legal capacity, as for complaints alleging denial of justice, the appellant must first exhaust the cantonal instance chain. The Federal Court reviews only whether the limits set by federal law were exceeded; therefore the higher cantonal authority must decide first.
