Motifs extraits
An order requiring security for costs is an interim decision. Such decisions are only appealable exceptionally under Art. 93 BGG, and the burden to establish admissibility lies with the appellant. The appeal contained no argument on admissibility, and no qualifying irreparable legal harm was evident.
