Sir
SCN is the foundation of matter of levy and recovery of duty, penalty, and interest. The Assessee is required to reply to the SCN following which an opportunity for a personal hearing will be granted to the Assessee. Thereafter the adjudicating officer shall pass the appropriate order in original.
A personal hearing gives you an opportunity to explain the details to the adjudicator in person. During the personal hearing, you must accompany your counsel so as to ensure that all the points have been well covered.
If the Assessee does not want to use the opportunity of personal hearing and gives it in writing, it literally means that he does not have anything more to say on the issue other than the points contained in the reply letter. In such cases, the adjudicator can pass the order. This is my view.
