Kernrechtsfrage
Whether R. established a new support residence in St. Gallen after leaving B./SG.
Extrahierter Entscheid
Yes. The police registrations and circumstances showed a new support residence in St. Gallen, despite temporary stays and clinic admission.
Extrahierte Begründung
Support residence follows the factual center of life and is ordinarily based on actual presence and intent to remain. For persons with addiction, unstable housing and weak social ties are not decisive. The presumed residence arising from registration was not rebutted by the canton.
