Question juridique clé
Whether the challenge to the April 10, 2012 decision refusing to set aside the partial judgment based on Art. 51 ZPO was admissible and whether Art. 51 ZPO applied intertemporally.
Solution extraite
Art. 51 ZPO did not apply to this pending case; the refusal concerning recusal was an appealable interlocutory decision, but the request to annul the earlier partial judgment under Art. 51 ZPO was not available.
Motifs extraits
Because the proceedings had begun before 1 January 2011, former cantonal procedural law governed until final judgment. Art. 405 ZPO did not extend to an Art. 51 ZPO request in this setting; that provision covers ordinary appeal remedies against decisions, not a special request against procedural acts during pending proceedings.
