WHAT IS THE DOCTRINE OF RESIDUAL POWERS?

> They  are  powers  which  the  trial  court  retains  even  after  the perfection of the appeal
> For  example:  X  was  charged  and  convicted  with  a  crime  so  he filed a notice of appeal.  If he wants to put up bail, where should he file his application?  If the records of the case have not been
transmitted to the appellate court, X can file the application with the trial court.  However, once the records have been transmitted to the appellate court, the trial court loses his jurisdiction over the bail application.
 

IS THE RULE ABSOLUTE?

> No,  if  the  decision  of  the  trial  court  upgraded  the  offense  from non-bailable  to  bailable,  the  application  should  be  filed  with  and could only be resolved by the appellate court
