19. Clearly, therefore, the stage of relevance, in adjudication proceedings, of the statement, recorded before a Gazetted Central Excise Officer during inquiry or investigation, would arise only after the statement is admitted in evidence in accordance with the procedure prescribed in clause (b) of Section 9D(1). The rigour of this procedure is exempted only in a case in which one or more of the handicaps referred to in clause (a) of Section 9D(1) of the Act would apply. In view of this express stipulation in the Act, it is not open to any adjudicating authority to straightaway rely on the statement recorded during investigation/ inquiry before the Gazetted Central Excise Officer, unless and until he can legitimately invoke clause (a) of Section 9D(1). In all other cases, if he wants to rely on the said statement as relevant, for proving the truth of the contents thereof, he has to first admit the statement in evidence in accordance with clause (b) of Section 9D(1). For this, he has to summon the person who had made the statement, examine him as witness before him in the adjudication proceeding, and arrive at an opinion that, having regard to the circumstances of the case, the statement should be admitted in the interests of justice.
