Sec.  6.  Effects  of  granting  a  new  trial  or  reconsideration.  –  The effects of granting a new trial or reconsideration are the following:

(a) When a new trial is granted on the ground of errors of law or irregularities  committed  during  the  trial,  all  the  proceedings  and evidence affected thereby shall be set aside and taken anew. The court  may,  in  the  interest  of  justice,  allow  the  introduction  of additional evidence.
 
(b) When a new trial is granted on the ground of newly-discovered evidence, the evidence already adduced shall stand and the newly-discovered  and  such  other  evidence  as  the  court  may,  in  the interest  of  justice,  allow  to  be  introduced  shall  be  taken  and considered together with the evidence already in the record.
 
(c) In all cases, when the court grants new trial or reconsideration, the  original  judgment  shall  be  set  aside  or  vacated  and  a  new judgment rendered accordingly.

 

WHAT  IS  THE  EFFECT  OF  THE  GRANT  OF  THE  MOTION  FOR  NEW TRIAL?

THE GRANT OF THE MOTION HAS THE FOLLOWING EFFECTS:

1.    If  it  is  based  on  errors  of  law  or  irregularities  committed  during the  trial,  a  trial  de  novo  ensues.    This  means  that  all  the proceedings and evidence affected by the error or irregularity will
be set aside.  The court may, in the interest of justice, allow the introduction of additional evidence.

2.    If  it  is  based  on  the  ground  of  newly  discovered  evidence,  the evidence  already  adduced  will  stand.    The  newly  discovered evidence  and  whatever  other  evidence  the  court  will  allow  to  be introduced  shall  be  taken  and  considered  together  with  the evidence already on record

3.    In    all    cases—whether    the    court    grants    new    trial    or reconsideration—the  original  judgment  shall  be  set  aside  or vacated and a new judgment rendered
 

WHY  IS  THE  ACCUSED  NOT  SUBJECTED  TO  DOUBLE  JEOPARDY WHEN A NEW TRIAL OR RECONSIDERATION IS GRANTED?

     First, because it is only granted upon motion of the accused
     Second, the first jeopardy is never terminated, since the original judgment is set aside and replaced with a new one
