Kernrechtsfrage
Whether the public-law appeal against the Grand Council's decision was admissible under political rights review.
Extrahierter Entscheid
Yes. The Federal Supreme Court had jurisdiction to review the cantonal authority's mandatory ex officio control of initiative validity, and the voter had standing as an elector.
Extrahierte Begründung
Cantonal law required the Grand Council to examine manifest conflicts with higher law ex officio; citizens thus have a right to proper review and may challenge the decision by way of political-rights appeal.
