Questão jurídica principal
Whether the cantonal decision on the wage basis for the widow's pension was an appealable intermediate decision.
Decisão extraída
Yes. It was an intermediate decision whose confirmation would otherwise expose the insurer to a potentially unlawful payment order that could not later be corrected.
Fundamentação extraída
The ruling fixed a binding legal premise for the later pension decision; if not reviewable now, the insurer could suffer irreparable prejudice because the claimant would likely not challenge a favorable final decision.
