Question juridique clé
Whether the appellant could challenge affiliation to the insurer and the duty to remain insured in 2007.
Solution extraite
The affiliation was valid and the appellant remained insured; a person domiciled in Switzerland is subject to compulsory health insurance, and he could not escape that duty.
Motifs extraits
The factual findings were not manifestly incorrect. The constitutional objections did not help because federal law is binding and compulsory insurance applies to Swiss residents.
