Natural justice obligations require clear, reasoned speaking orders and transparent show cause procedure to reduce litigation and ensure compliance. Guidelines require GST adjudication orders to be clear, concise and legally sound, delivering speaking orders that set out facts, statutory provisions applied, evidence analysis, and reasons for acceptance or rejection of taxpayer contentions. Adjudicating authorities must respect Natural Justice - impartiality, fair hearing, and reasoned decisions - by issuing comprehensive show cause notices, permitting inspection and copies of relied documents, recording personal hearings, allowing cross examination and adjournments, and quantifying tax, interest and penalty with transparent calculations while specifying remedies and appeal avenues.
