Question juridique clé
Whether the complaint was premature and which procedural law applied after the Erwahrungsbeschluss.
Solution extraite
The complaint was premature when filed, but the relevant federal procedural regime was the BGG because the Erwahrungsbeschluss was issued in 2007; the filing is treated as a public-law complaint under the BGG.
Motifs extraits
For referendable cantonal enactments, abstract constitutional review begins only upon publication of the official confirmation of enactment, not upon parliamentary adoption or referendum publication. Because that confirmation occurred after 1 January 2007, the BGG applied.
