Kernrechtsfrage
Whether the insured had established residence in Y. before 1 November 2004 for premium purposes
Extrahierter Entscheid
He had not shown a residence change to Y. before 1 November 2004; the insurer could rely on the cantonal premium applicable to A. until then.
Extrahierte Begründung
Residence under Art. 13 ATSG and Art. 23 ff. ZGB depends on the center of life relations, not merely declared intention. The available evidence showed only temporary stays and late registration; the cantonal court could give decisive weight to the municipal registration.
