Key legal question
Whether the Department validly notified the order requiring an advance of costs, so that the appeal deadline for payment expired.
Extracted holding
The order was validly notified by postal service; the appellant failed to rebut the presumption of delivery, so the advance-cost deadline expired without payment.
Extracted reasoning
Track-and-trace data and the original envelope showed postal notification and expiry of the holding period; the authority had no duty to attempt re-service after the item was returned.
