Suspension or revocation procedure requires notice, inquiry with evidence and representations, and permits penalty and appeal. The Principal Commissioner of Customs or Commissioner must issue a written notice of proposed suspension or revocation stating grounds and allow the Customs Cargo Service provider a minimum period to submit a written defence to a nominated Assistant or Deputy Commissioner and to request oral hearing. The Assistant or Deputy Commissioner may inquire into non admitted grounds, receive documentary and oral evidence, allow cross examination, record reasons for excluding evidence, and prepare a report. The Principal Commissioner or Commissioner shall furnish that report to the provider, allow representations, and thereafter decide on orders; contraventions attract a monetary penalty and appeals lie under the Act.
