Questão jurídica principal
Whether the appeal remained admissible despite the sale of the disputed condominium units.
Decisão extraída
No current and practical interest remained because the canton-court judgment had already been executed by the sale of the units.
Fundamentação extraída
A federal appeal requires an actual, practical interest. Once the challenged exclusion order and sale obligation had been carried out through the transfer of the units, the dispute was no longer live.
