Key legal question
Whether the Free Movement Agreement applies to a person with both Swiss and EU citizenship.
Extracted holding
Yes. If a person holds both Swiss citizenship and the citizenship of an EU member state, the Free Movement Agreement applies; the Foreign Nationals Act applies only subsidiarily or if it is more favorable.
Extracted reasoning
Dual citizenship does not exclude the FZA. Domestic law governs only where the agreement contains no divergent rule or where it grants a more advantageous status.
