Question juridique clé
Whether the appellants had standing to challenge the partial closure order
Solution extraite
A.________ SA had standing because the seized documents were taken in its offices; B.________ SA also had standing as owner of the premises. The other companies were not clearly shown to be directly affected.
Motifs extraits
Only persons personally and directly affected may appeal. For searches, standing belongs to the owner or tenant of the premises; mere mention in seized documents is insufficient.
