Key legal question
Whether the cantonal court had to examine additional recusal grounds first raised in written observations.
Extracted holding
No. The recusal request had to comply with the formal requirements of Art. 47 CPC/VD, and the additional grounds were not properly filed in that form.
Extracted reasoning
A court does not violate the right to be heard when it limits review to recusal requests made in the legally prescribed form; the appellants failed to show arbitrariness in applying the formal rule.
