Departmental appeal screening and zonal law committees streamline GST litigation review, uniformity, and revenue protection. Guidelines prescribe the manner in which departmental appeals under the UPGST framework are to be considered for filing before the GST Appellate Tribunal, the High Court and the Supreme Court, subject to monetary limits and specified exceptions. A Zonal Law Committee is constituted at each zonal level to review first appellate decisions, protect revenue interests, examine the quality of adjudicatory orders, and promote uniformity in appellate decision-making. The committee must meet at least twice a month, maintain records, prepare detailed minutes, identify speaking orders and best practices, and forward poor-quality orders and accountability reports to headquarters.
