Questão jurídica principal
Whether the civil-law appeal was admissible despite the low amount in dispute because of a legal question of principle.
Decisão extraída
The appeal was inadmissible because the value in dispute was only CHF 4,500 and the appellants had not properly challenged the first-instance decision required to invoke a legal question of principle.
Fundamentação extraída
When the cantonal appeal court reviews only arbitrariness, a party relying on Art. 74(2)(a) BGG must also challenge the first-instance judgment and engage with its reasoning; this was omitted.
