Questione giuridica chiave
Whether the revision criteria justified terminating the quarter invalidity pension.
Decisione estratta
The pension could not be revoked because the earning-capacity assessment was not changed in a rent-relevant way; the insured remained entitled to a quarter pension beyond 2011-12-31.
Motivazione estratta
The Federal Court held that the use of statistical wage level 3 was not justified on the findings. No sufficient basis showed that the insured had acquired the broader professional skills required for the total economy wage or could draw on special abilities to earn more than before; the proper reference remained level 4, so no rent-relevant change was established.
