Question juridique clé
Whether the supervisory authority's 26 July 2000 letter withdrawing the earlier partial-liquidation instruction was valid and had to be notified to interested destinaries and the new employer.
Solution extraite
The withdrawal had supervisory character and had to be communicated also to the destinaries and the new employer; the late appeal was therefore not time-barred.
Motifs extraits
A supervisory decision on partial liquidation remains such even if reconsidered; non-service cannot prejudice parties. Destinaries and the new employer were directly affected and could challenge it once they learned of it.
