Question juridique clé
Whether the invalidity pension could be suspended during inpatient measure enforcement under Art. 21(5) ATSG.
Solution extraite
Yes. Suspension is sufficient if the person's social dangerousness made the measure necessary; it need not have been the sole or predominant reason.
Motifs extraits
The measure was clearly based on non-negligible social dangerousness, and no additional factual clarification was required.
