The appeal is inadmissible because the challenged matter concerns a non-final interlocutory decision and the appellants did not show a non-reparable harm or any other ground for immediate review under Art. 93 BGG.
Motivazione estratta
The underlying stay of proceedings was an interlocutory order; the revision and non-entry decisions relating to it were likewise interlocutory. The appellants failed to demonstrate the conditions for appealability under Art. 93 BGG.
