Key legal question
Whether the cantonal court president and clerk had to recuse themselves because they had earlier issued the supervisory instruction in the same matter.
Extracted holding
Yes. Their earlier supervisory instruction and later appellate review concerned the same legal questions, so prior involvement created an appearance of bias.
Extracted reasoning
A judge or clerk who has already taken a detailed supervisory position on the same concrete dispute cannot later review the implementing decision on appeal; this is especially true where the lower authority merely followed the instruction without independent reassessment.
