Key legal question
Whether mere denial of receiving the pickup notice defeats proof of valid service when a decision is sent by registered or court mail.
Extracted holding
No. If service is made by court post or registered mail, a mere denial of having received the pickup notice is insufficient to prevent proof of valid service.
Extracted reasoning
The court held that the service method itself creates a sufficient basis for proof of delivery; the addressee's unsupported denial does not rebut that proof.
