Kernrechtsfrage
Whether the objection decision of 14 May 2008 was validly served on the appellant's representative.
Extrahierter Entscheid
The court held that service was sufficiently proven because the decision was addressed to the lawyer previously notified as representative and was collected from the PO box by an authorized person.
Extrahierte Begründung
Once a representation relationship has been notified to an authority, the authority may generally rely on its continuation until a revocation is communicated. The lower court's finding that the registered letter was collected by an entitled person was an assessment of evidence based on common experience, not a burden-of-proof error.
