Advance ruling binding effect limited to the applicant and officers; ceases if law or facts change. Advance rulings are binding only on the applicant who sought the ruling and the concerned and jurisdictional officers in respect of that applicant; where conflicting State appellate rulings lead to a national ruling, that national ruling binds the applicants who sought it, all registered persons sharing the same Permanent Account Number, and the relevant officers. Binding subjects include classification, applicability of notifications, time and value of supply, input tax credit admissibility, tax liability, registration necessity, and whether an activity constitutes a supply. The ruling stops being binding if law, facts, or circumstances change, and it does not bind other taxpayers or distinct persons of the applicant.
