Question juridique clé
Whether the revision-based reduction of the disability pension from a full to a half pension as of 1 October 2004 was lawful.
Solution extraite
The record was insufficient to determine the claimant's work capacity throughout the relevant period, so the reduction could not be upheld.
Motifs extraits
The medical evidence did not adequately clarify the impact of tinnitus, headache complaints, and the later scrotal pain condition on work capacity; a broader interdisciplinary assessment was required before deciding the pension entitlement from 1 October 2004.
