Either Party may call on the other Party by Notice to admit any Document, saving all just Exceptions; and in case of Refusal or Neglect to admit, the Costs of proving the Document shall be paid by the Party so neglecting or refusing, whatever the Result of the Cause may be, unless at the Trial the Judge shall certify that the Refusal to admit was reasonable; and no Costs of proving any Document shall be allowed unless such Notice be given, except in Cases where the Omission to give the Notice is in the Opinion of the Master a Saving of Expense.
