Question juridique clé
Whether the cantonal court acted arbitrarily in treating the municipal claim as timely after extending the lawsuit deadline.
Solution extraite
No arbitrariness was shown; the deadline was an extendable claim period, not a peremptory appeal period.
Motifs extraits
Art. 154 Abs. 3 ZPO/GR allows the magistrate either to decide or set a deadline to sue; under Art. 60 Abs. 1 ZPO/GR only appeal deadlines and expressly peremptory deadlines are non-extendable.
