Questão jurídica principal
Whether the reform appeal against the cantonal remand decision was admissible under Art. 50 OJ
Decisão extraída
Yes. The challenged ruling was incidentally final on the rejected claims, and immediate federal review could avoid lengthy and costly expert proceedings on the remaining claim.
Fundamentação extraída
A different cantonal outcome would have fully ended the dispute; the ordered expertise concerned old and specific repair defects and would likely be time-consuming and expensive.
