Key legal question
Whether the denial of access to the liability-file was an appealable final decision or an interlocutory decision requiring Art. 93 BGG conditions.
Extracted holding
The access ruling was interlocutory because it formed part of the pending liability proceedings and did not end them.
Extracted reasoning
The request was not an autonomous data-protection procedure; the applicable law was the procedural law of the liability case. Therefore the cantonal judgment was an interlocutory decision subject to Art. 93 BGG.
