Kernrechtsfrage
Whether the refusal to recuse the cantonal judges violated the constitutional right to an impartial tribunal.
Extrahierter Entscheid
No. Prior participation in earlier decisions on the same matter did not, by itself, justify an appearance of bias in the later revision proceedings.
Extrahierte Begründung
The Court held that prior involvement creates concern only if the concrete legal question no longer appears open. Rehearing by the same judges in revision is not per se incompatible with Art. 30 BV or Art. 6 ECHR, and the appellant showed no specific prejudice.
