Under section 33(3) VwGVG, the restoration application must be made within two weeks after the obstacle has ceased. The application therefore needs a coherent chronology: when did the event begin, why did it prevent timely action, when did it cease and when was the party able to act again?
The date on which the obstacle ceased should not merely be asserted. Depending on the case, relevant material may include service records, medical confirmation, technical logs, proof of absence or documented communications. The suitable evidence depends on the specific event. Do not infer a binding final date from an online result.
