Question juridique clé
Whether the cantonal decision annulling the conciliation leave-to-sue was itself reviewable and correct
Solution extraite
The cantonal court had no competence to review or annul the leave-to-sue; the respondent had no appeal against it.
Motifs extraits
An authorization to proceed is not an appealable decision; its validity is examined by the court seized of the merits when assessing admissibility. The cantonal court therefore wrongly entertained the challenge and could not order the authorization set aside.
