Question juridique clé
Whether the Federal Court could hear an appeal against the cantonal stay order in Lugano exequatur proceedings.
Solution extraite
Yes, the appeal was admissible against the interim stay order, and no irreparable harm was required because the complaint alleged undue delay/denial of justice.
Motifs extraits
A stay of opposition proceedings is an incidental measure. Where the appellant complains of unjustified procrastination of proceedings, the irreparable-harm requirement of Art. 93(1)(a) LTF is waived.
