Key legal question
Whether the appellant had to be insured in Switzerland as a person without gainful activity and pay AVS/AI/APG contributions for 2000-2005.
Extracted holding
The lower factual findings on her professional status in France were incomplete; the case had to be sent back for additional investigation before a final ruling on Swiss affiliation and contributions could be made.
Extracted reasoning
The absence of affiliation with the French fund alone did not prove lack of gainful activity because the relevant French status was optional until end-2005. A competent French institution had to clarify whether she was engaged in gainful activity and how that activity was qualified during the whole relevant period.
