Key legal question
Whether the claimant was entitled to a full invalidity pension instead of a three-quarter pension.
Extracted holding
No. The calculated invalidity degree remained below the threshold for a full pension, even assuming the highest permissible wage deduction.
Extracted reasoning
The lower authorities' income comparison based on the regional medical service assessment was not shown to be arbitrary; at most, the invalidity degree would reach 67%, which is insufficient for a full pension.
