Questão jurídica principal
Whether the appellant had a Swiss domicile for purposes of security for costs under Art. 99(1)(a) CPC.
Decisão extraída
He did not establish an effective Swiss domicile; mere registration or re-registration was insufficient.
Fundamentação extraída
The relevant domicile is the actual civil-law domicile under Art. 23 CC, assessed by objective, third-party-visible circumstances. The record showed only that he had left B. and no facts proved a new center of life in C. or elsewhere in Switzerland.
