Question juridique clé
Whether denial of receipt of the pickup notice defeats proof of valid service of a decision sent by registered mail or court delivery
Solution extraite
A bare denial of having received the pickup notice is not enough to prevent proof of valid service when the decision was sent by registered mail or court delivery.
Motifs extraits
Service by court delivery or registered mail is established by the mailing method itself; the addressee's mere assertion that the notice was not received does not by itself rebut valid service.
