Key legal question
Whether the withholding of earlier administrative files violated the right to be heard and file-completeness requirements.
Extracted holding
Yes. The earlier files could be relevant to determining the insured person's hypothetical work status, so withholding them from the cantonal court seriously breached the right to be heard.
Extracted reasoning
The scope of file inspection depends on the objective relevance of documents to the decisive facts. Because the dispute concerned a hypothetical status change, earlier files from the first pension claim could shed light on that issue and had to be submitted.
