Key legal question
Whether the cantonal ruling rejecting the res judicata objection was directly challengeable by reform appeal
Extracted holding
No. The cantonal judgment was an incidental decision under Art. 50 OJ, and the appellant did not show the exceptional conditions for immediate reform appeal.
Extracted reasoning
The decision did not concern jurisdiction under Art. 49 OJ. Immediate review of an incidental decision is possible only exceptionally when a final decision can be obtained at once and the evidence procedure would otherwise be excessively burdensome; the appellant failed to demonstrate this.
