Witness allowance payable: summoned persons receive government travel and daily allowances or Registrar estimated expenses upon deposit. Government servants summoned by the Appellate Tribunal may draw government travelling and daily allowances; if the employer makes no provision, the Registrar shall estimate a sum to cover reasonable travelling and other expenses, which the applicant must deposit before the summons is issued; court witness payments shall be made as directed by the Tribunal, and the same provisions apply to interpreters.
