Under four tax legislations: Inheritance Tax Act (2015), Excise Act (2017), Customs Act (2017), and Land and Building Tax Act (2019), if the Appeal Committee cannot complete an appellate procedure within the prescribed period of time, an appellant can file a suit in a court without having to wait for the consideration. This process is different from that of the Act for the Establishment of and Procedure for Tax Court (1985) Section 8. The article explores issues and confusions arising from such difference.
