Question juridique clé
Whether the prior federal judgment was incomplete and had to be rectified under Art. 129 LTF regarding cantonal costs and expenses.
Solution extraite
The dispositive was incomplete because the court had inadvertently failed to decide the cantonal costs and expenses after modifying the appealed decision; rectification was therefore justified.
Motifs extraits
When the Federal Court modifies the challenged decision, it may reallocate previous-instance costs or remand that question. Here, the omission to address the cantonal costs and expenses made the dispositive incomplete within Art. 129(1) LTF.
