Questione giuridica chiave
Whether the compensation office could rely on a hypothetical income in the supplementary benefits calculation without properly warning the insured person when extending the deadline for submissions.
Decisione estratta
The office could not simply decide on the file without having first warned the insured person that failure to comply with the final deadline would lead to a decision on the existing record.
Motivazione estratta
Art. 40(2) ATSG is a protective rule: when an authority sets a deadline for a specific act, it must also threaten the consequences of non-compliance. The office gave deadline extensions for the reasoning and work-search proof, but did not clearly announce that it would decide on the file if the deadline expired unused.
