Key legal question
Whether the revision-based cancellation of the long-standing half invalidity pension was lawful.
Extracted holding
The pension could not be fully cancelled on the basis applied by the IV office; the appeal was dismissed and the cantonal judgment remained in force.
Extracted reasoning
The court held that the hypothetical career without disability must be assessed on the basis of all circumstances up to the revision date. The insured's interim advancement and the employer's confirmation of a possible career to team leader made it sufficiently probable that a higher valid income should be taken into account.
