All-India adjudication jurisdiction for specified additional/joint commissioners enables centralized adjudication of multi-jurisdiction show cause notices. The amendment empowers specified Additional/Joint Commissioners with All India jurisdiction to adjudicate show cause notices issued by intelligence officers when noticees' principal places of business fall under multiple commissionerates or multiple notices on the same issue exist; ordinarily, intelligence and audit officers only issue notices which are adjudicated by the executive commissionerate where the noticee is registered. Principal Commissioners will allocate charge of adjudication to a designated Additional/Joint Commissioner per a zone-to-commissionerate table, and corrigenda may make pre-existing unadjudicated notices answerable to the All India adjudicators. Audit commissionerate cases may be referred for appointment of a common adjudicating authority.
