Manual GST appeal filing continues where the online appeal module cannot properly route enforcement unit appeals. Manual appeal filing under GST continues for enforcement unit orders because the online appeal module is not yet fully operational. Appeals may appear on the login ID of the division-linked appellate authority even where the designated appellate authority is the enforcement unit's appointed officer, and the module presently lacks appeal-transfer functionality. Technical issues are also noted for certain central tax and unregistered inter-State cases, so the earlier manual procedure remains in force until further orders.
