Whether the appeal had to be declared inadmissible because the appellant failed to pay the required advance on costs within the prescribed extended time limit.
Yes. The appellant did not pay the advance despite repeated extensions, so the appeal was inadmissible and the case was removed from the docket.
Under Art. 49(2) OELP, the recourse party must advance the court fee. The appellant had been warned that failure to do so would result in inadmissibility; since no advance was paid by the final deadline, the appeal could not be examined.
