GST appeals must be filed within three months of communication of the order. The appellate authority may admit a delayed appeal only on sufficient cause and only during the further one-month period expressly permitted by the statute. The Limitation Act does not apply to enlarge this limited condonation power where the GST appellate scheme does not provide for such application. An appeal filed after both periods, particularly where the substantial delay remains inadequately explained, is time-barred and cannot be entertained.
