Interception of conveyances: tolerable e-way bill and document errors avoid seizure but attract prescribed penalties. The circular clarifies that absence of required documents or an invalid Part B makes an e-way bill invalid and may invite detention and seizure; however, where a consignment carries both a specified document and a valid e-way bill, listed minor discrepancies (such as small name, PIN, address, document number, HSN or vehicle number errors) should not lead to seizure proceedings, but a prescribed penalty must be imposed and those consignments recorded and reported weekly to the controlling officer.
