Key legal question
Whether the revision reducing the disability pension to a quarter pension as of 2005-10-01 was lawful.
Extracted holding
The reduction was upheld because the insured person's state of health had improved and the degree of invalidity was correctly reassessed.
Extracted reasoning
The court found no error in the revision assessment; the comparison-of-income method remained applicable and the cantonal judgment correctly applied the relevant rules on invalidity revision.
