Sec. 9. Cases not requiring a preliminary investigation nor covered by  the  Rule  on  Summary  Procedure.  –  (a)  If  filed  with  the prosecutor. – If the complaint is filed directly with the prosecutor involving an offense punishable by imprisonment of less than four (4) years, two (2) months and one (1) day, the procedure outlined in section 3(a) of this Rule shall be observed. The prosecutor shall act on the complaint based on the affidavits and other supporting documents submitted by the complainant within ten (10) days from its filing.
(b)  If  filed  with  the  Municipal  Trial  Court.  –  If  the  complaint  or information  is  filed  with  the  Municipal  Trial  Court  or  Municipal Circuit  Trial  Court  for  an  offense  covered  by  this  section,  the procedure in section 3 (a) of this Rule shall be observed. If within ten  (10)  days  after  the  filing  of  the  complaint  or  information,  the judge  finds  no  probable  cause  after  personally  evaluating  the evidence, or after personally examining in writing and under oath the  complainant  and  his  witnesses  in  the  form  of  searching questions  and  answers,  he  shall  dismiss  the  same.  He  may, however, require the submission of additional evidence, within ten (10)  days  from  notice,  to  determine  further  the  existence  of probable  cause.  If  the  judge  still  finds  no  probable  cause  despite the  additional  evidence,  he  shall,  within  ten  (10)  days  from  its submission or expiration of said period, dismiss the case. When he finds  probable  cause,  he  shall  issue  a  warrant  of  arrest,  or  a commitment  order  if  the  accused  had  already  been  arrested,  and hold him for trial. However, if the judge is satisfied that there is no necessity  for  placing  the  accused  under  custody,  he  may  issue summons instead of a warrant of arrest.
