Sec. 12. Withdrawal of appeal. - Notwithstanding perfection of the appeal, the Regional Trial Court, Metropolitan Trial Court, Municipal Trial Court in Cities, Municipal Trial Court, or Municipal Circuit Trial Court, as the case may be, may allow the appellant to withdraw his appeal before the record has been forwarded by the clerk of court to  the  proper  appellate  court  as  provided  in  section  8,  in  which case,  the  judgment  shall  become  final.  The  Regional  Trial  Court may  also, in its discretion, allow  the appellant from  the judgment of  a  Metropolitan  Trial  Court,  Municipal  Trial  Court  in  Cities, Municipal  Trial  Court,  or  Municipal  Circuit  Trial  Court  to  withdraw his appeal, provided a motion to that effect is filed before rendition of the judgment in the case on appeal, in which case the judgment of  the  court  of  origin  shall  become  final  and  the  case  shall  be remanded to the latter court for execution of the judgment.
 

CAN   AN   APPEAL   THAT   HAS   ALREADY   BEEN   PERFECTED   BE WITHDRAWN BY THE APPELLANT?

     If  the  records  have  not  yet  been  transmitted  to  the  appellate court, the court that rendered the judgment has the discretion to allow the appellant to withdraw the appeal
     If the appeal is withdrawn, the judgment shall become final
     If  the  records  have  already  been  transmitted  to  the  appellate court,  only  the  appellate  court  may  decide  whether  to  grant  the motion to withdraw the appeal, and not only before the judgment is rendered in the case of appeal
