Art. 46 BV; Art. 2 der Uebergangsbestimmungen; domicile principle and standing to complain of cantonal sovereignty. The domicile rule of Art. 46 BV was not yet directly applicable absent the implementing federal legislation foreseen by the Constitution; until such legislation, no individual may derive a justiciable claim from that provision. A complaint alleging encroachment upon a canton’s sovereignty is reserved to the affected canton itself; a private party lacks standing to invoke such a public-law grievance.
