Art. 1 and Art. 3 Federal Act of 25 June 1891; scope ratione materiae of the federal domicile definition; public-law residence control and tax matters excluded. The Act governs only specified civil-, family- and inheritance-law consequences of domicile and residence. Its statutory concept of domicile applies directly only where a relationship falling within the Act is at issue. It does not determine domicile for police regulation of settlement and stay, nor for taxation. A complaint based solely on Art. 3 is therefore inadmissible or, at any rate, unfounded in public-law disputes; a later challenge remains reserved if a cantonal measure is used for fiscal purposes (consid. 2-3).
