Question juridique clé
Whether the withdrawal of already granted legal aid was lawful despite no changed circumstances.
Solution extraite
Legal aid may be withdrawn only if the entitlement no longer exists because circumstances changed after the initial grant, and the withdrawal is in principle only prospective; no such change was shown here.
Motifs extraits
The same documents were already known when legal aid was granted. The cantonal court identified no new evidence or post-decision change in prospects. A retroactive withdrawal is exceptional and not justified on the facts.
