Issue of notice before imposing penalty: 

Rule 26 of the said Rules also provides that before any order of penalty or confiscation is passed the adjudicating authority shall follow the principles of natural justice. In other words a notice explaining the reasons why penalty should not be imposed or goods confiscated has to be given to the person. Thereafter, reasonable opportunity shall be given to such person to explain or defend his case. The adjudicating Officer shall pass a reasoned order, incorporating the defence arguments given by such person or his authorised representative.
