Kernrechtsfrage
Whether the public law appeal was admissible for all appellants despite missing valid powers of attorney and a withdrawn canton-level appeal
Extrahierter Entscheid
Many appellants lacked valid authorization; one appellant's 1998 appeal was already withdrawn in cantonal proceedings, so the appeal was inadmissible for those persons.
Extrahierte Begründung
Under Art. 30 para. 2 OJ, defects not cured after notice lead to non-consideration; the file also showed a prior withdrawal for one appellant.
