Questione giuridica chiave
Whether child allowances must be included in presumptive lost earnings for pension over-coverage calculation.
Decisione estratta
No. Under the applicable pension regulations, presumptive lost earnings are based on AHV-wage income, which does not include child allowances.
Motivazione estratta
The regulation's wording was clear: the reference to the AHV wage fixes the benchmark, and child allowances are excluded from AHV wage income. The court found no basis to apply the contra proferentem rule or to infer that the regulation adopted the statutory over-insurance rule for mandatory benefits.
