Question juridique clé
Whether the appeal remained admissible despite the seizure order having already exhausted its effects.
Solution extraite
No; the appellants lacked a current and practical interest because the posters related only to a vote that had already taken place.
Motifs extraits
The challenged provisional measure had fully produced its effects once the referendum was over. The exception for issues capable of repetition did not apply, because the situation concerned a specific campaign and a sufficiently likely recurrence in identical circumstances was not shown.
