Whether the civil appeal had to be dismissed for failure to pay the required advance of costs within the additional deadline.
Yes. The advance was paid only on 25 June 2014, after the extended deadline expired on 23 June 2014, so the appeal was inadmissible.
Under Art. 98 and 101(3) CPC, failure to pay the advance within the additional non-extendable deadline prevents the court from entering into the matter. The late cash payment at the post office was therefore ineffective.
