Kernrechtsfrage
Whether the pension revision and reduction from half to quarter pension were justified.
Extrahierter Entscheid
No. The court held that the insured person still had a right to a half invalidity pension and that no revision ground existed.
Extrahierte Begründung
The decisive factor was the hypothetical valid income. Based on the claimant's career development, the court found it overwhelmingly likely that she would have followed the same path in good health and would be working as a care assistant. Because her medical incapacity remained unchanged, the earlier half pension remained justified; a numerical income comparison was unnecessary.
