Question juridique clé
Whether the abstract challenge to the new cantonal law was admissible despite the referendum period and prematurity.
Solution extraite
The filing was not inadmissible for prematurity; the appeal could be examined on the merits because premature filing usually only suspends the case.
Motifs extraits
For referendum-subject normative acts, the federal time limit runs from promulgation, not initial publication; premature filing does not bar review.
