Key legal question
Whether early retirement at age 58 required a new, lower valid income and thus justified pension revision from 1 October 2015.
Extracted holding
Because early retirement in this highly qualified occupation was generally dictated by safety reasons, the valid income had to be reassessed on the basis of a different post-retirement activity. That constituted a revision ground if it led to a substantial change.
Extracted reasoning
The court distinguished safety-based early retirement from socially motivated early retirement. Only the former allows reliable inferences that the insured would no longer remain in the former job and would likely change occupation.
