Art. 63 Ziff. 4 Abs. 2 O.G.; appeal admissibility against enforcement decisions: Federal Court jurisdiction by appeal extends only to cantonal judgments deciding a material civil claim, whether in ordinary or expedited proceedings. Decisions rendered in enforcement proceedings are excluded from appeal, even if formally styled as judgments. A bankruptcy opening is an enforcement measure and does not determine a substantive right; an appeal directed against such a decision is therefore inadmissible.
