Question juridique clé
Whether the cantonal appeal was admissible against the refusal to order another institution than the SPMi to prepare the social report.
Solution extraite
The appeal was inadmissible insofar as it challenged the refusal to treat the matter as a reviewable recusal decision or as an incident causing irreparable harm.
Motifs extraits
A preventive recusal request against an entire service can be abusive and therefore inadmissible; in any event, the appellant failed to show a legally irreparable prejudice from the evidentiary order.
