Question juridique clé
Whether the conditions for revising the disability pension were met under the applicable social insurance rules.
Solution extraite
Yes. The office was entitled to revise the pension ex officio because the causal health condition could improve and the file showed a relevant change in circumstances.
Motifs extraits
The court held that the administration had repeatedly reviewed the case and gathered sufficient information. The decisive issue was whether the insured's condition had materially changed, not whether the original grant had been correct.
