Key legal question
Whether a Swiss-resident independent worker is exempt from AVS/AI insurance because the activity lasted less than three months.
Extracted holding
No. The short-duration exemption under Art. 1a(2)(c) LAVS applies only if the person is not domiciled in Switzerland.
Extracted reasoning
The respondent was domiciled in Switzerland before, during, and after the activity; therefore he remained compulsorily insured under Art. 1a(1)(a) LAVS and could not rely on the short-duration exemption.
