Question juridique clé
Whether the municipal property tax levied by Waldkirch and Niederbüren constituted unconstitutional double taxation.
Solution extraite
No. Only St. Gallen and its municipalities claimed tax power over the property located in their territory; no competing taxation by another canton existed.
Motifs extraits
Double taxation in the federal sense requires competing tax claims by several cantons over the same taxpayer and object. Here only the St. Gallen real estate was taxed in St. Gallen.
