Reasoned and speaking appellate GST orders must address material grounds of appeal and cited precedents; merely confirming an ex parte demand for lack of satisfactory evidence fails to exercise appellate jurisdiction. Where original adjudication occurred ex parte and objections concerning notice, relied-upon documents, and hearing remain unresolved, remand for fresh original adjudication preserves the appellate remedy. Fresh proceedings require identification and access to relied-upon documents, a reasonable opportunity to respond, an effective personal hearing, and reasoned findings based on evidence. Non-participation without sufficient cause permits determination on the existing record, but not without reasons.
