Questione giuridica chiave
Whether the federal appeal against the cantonal remand judgment was admissible as a final decision or under Art. 93 LTF.
Decisione estratta
The challenged remand judgment was an incidental decision and did not satisfy the requirements for immediate federal review.
Motivazione estratta
The decision did not end the dispute but only required a new allocation of remediation costs. No irreparable prejudice was shown, and neither the continuation of proceedings nor higher costs were sufficient. The case was also not unusually complex or costly so as to justify immediate review.
