Key legal question
Whether a self-employed person domiciled in Switzerland can invoke the short-duration exemption from AVS coverage under Art. 1a para. 2 let. c LAVS.
Extracted holding
No. The short-duration exemption applies only if the person is not domiciled in Switzerland; Swiss domicile entails mandatory AVS/AI coverage.
Extracted reasoning
The wording and purpose of Art. 1a para. 2 let. c LAVS, read with Art. 1a para. 1 LAVS, show that the exemption is tied to lack of Swiss domicile. The respondent was domiciled in Switzerland before, during and after the activity.
