Key legal question
Whether the public law appeal could seek instructions beyond mere annulment and whether a second exchange of briefs was required
Extracted holding
The appeal is cassatory in principle; requested instructions were not admissible, and no second exchange of briefs was warranted because no new relevant arguments were raised in the response.
Extracted reasoning
A public law appeal generally allows only annulment. A second written exchange is exceptional and depends on the content of the response, not on case complexity. The appellant did not show new arguments requiring a reply.
