Kernrechtsfrage
Whether the disability pension had to be increased due to a relevant health deterioration
Extrahierter Entscheid
The court found no proven relevant deterioration since the 2009 revision decision; the half pension remained unchanged.
Extrahierte Begründung
The 2014 and 2017 multidisciplinary expert reports were convincing and consistently found no material change in health or work capacity. In an adapted job, full work capacity remained medically sustainable.
