Ans. Section 104(1) provides that an advance ruling shall be held to be ab initio void if the AAR or AAAR finds that the advance ruling was obtained by the applicant by fraud or suppression of material facts or misrepresentation of facts. In such a situation, all the provisions of the GST Act(s) shall apply to the applicant as if such advance ruling had never been made (but excluding the period when advance ruling was given and up to the period when the order declaring it to be void is issued). An order declaring advance ruling to be void can be passed only after hearing the applicant.
