Kernrechtsfrage
Whether the revision-based increase of the disability pension should be granted from 1 February 2007 instead of 1 July 2010
Extrahierter Entscheid
The pension increase was not proven earlier than 1 July 2010; the appeal against the later start date failed.
Extrahierte Begründung
The court held that a lasting psychiatric deterioration was not established with sufficient probability, while a relevant somatic worsening due to multiple sclerosis was only proven from the first relapse in April 2010. The prior income assessment was final and could not be challenged again.
