Stay petitions: procedural filing, service and evidentiary requirements govern suspension of departmental orders. Applications for stay of operation of impugned orders must be presented in triplicate to the Registrar or authorised officer at the Tribunal bench having jurisdiction with simultaneous service on the authorised representative of the Principal Commissioner/Commissioner or Administrator. Applications, to be typed in English, must concisely state facts of the demand, the exact duty or penalty and undisputed portion, appeal details, prior proceedings, reasons for stay, willingness to furnish security and precise prayers. They must be accompanied by three copies of relevant departmental orders and supporting documents; non compliance may lead to summary rejection. Verification is required and the Bench may direct affidavits where necessary.
