Question juridique clé
Whether the insurer could appeal the cantonal remand decision immediately under Art. 93 BGG.
Solution extraite
The remand decision was an independently appealable interim decision because it imposed materially binding instructions and caused irreparable prejudice to the insurer.
Motifs extraits
The insurer was compelled to issue a new decision despite disputing ongoing liability; its discretion was significantly curtailed and the decision could not later effectively be challenged.
