Complaint inquiry procedure governs removal of GST Appellate Tribunal President or Member through scrutiny, committee inquiry, and natural justice. Procedure is prescribed for inquiry into a written complaint alleging a definite charge against the President or a Member of the Goods and Services Tax Appellate Tribunal. The Central Government must first make a preliminary scrutiny of the complaint, and if it finds reasonable grounds for inquiry, it is to refer the matter to the concerned Committee. After the inquiry, the Committee must submit its report with separate findings and reasons on each charge, while following the principles of natural justice and regulating its own procedure.
