Kernrechtsfrage
Whether revision was warranted under Art. 121 lit. d BGG for overlooked material facts in judgment 9C_569/2009.
Extrahierter Entscheid
No revision ground was shown because the cited materials were not overlooked in a legally relevant sense and did not concern an overlooked decisive fact.
Extrahierte Begründung
The court noted that its prior judgment already proceeded from the same legal framework; the applicant mainly challenged the legal assessment and the scope of the remittal, not any omitted decisive factual element.
