Whether the Geneva enforcement office could revoke a levy report after the complaint deadline on the ground of nullity.
No. After the complaint period had expired, revocation was only possible if the earlier act was absolutely null; the 15 December 2008 act was not null.
A later ex officio reconsideration is admissible only while the complaint period runs, or, exceptionally, when the act is void under Art. 22 LP. Here, once a certificate of loss had been issued, third-party participation interests were not at risk, so the prior act was at most contestable, not void.
