Question juridique clé
Whether the licence-withdrawal decision was deemed validly served on 22 March 2002 under the postal service fiction.
Solution extraite
Yes. Because the administrative proceedings had already created a duty to ensure delivery, the uncollected registered notice was deemed served at the end of the collection period.
Motifs extraits
After the hearing letter and the driver's own contact with the authority, a procedural relationship existed and he had to ensure receipt of official acts; the cantonal court's application of service fiction was not arbitrary.
