Upon application of a defendant who on the basis of a felony complaint
  has  been held by a local criminal court for the action of a grand jury,
  and who, at the time of such  order  or  subsequent  thereto,  has  been
  committed  to the custody of the sheriff pending such grand jury action,
  and who has been confined in such custody for  a  period  of  more  than
  forty-five  days,  or,  in the case of a juvenile offender, thirty days,
  without the occurrence of any grand jury action or disposition  pursuant
  to  subdivision  one, two or three of section 190.60, the superior court
  by which such grand jury was or is to be impaneled must release  him  on
  his own recognizance unless:
(a)  The  lack  of  a  grand  jury  disposition  during such period of
  confinement was due to the defendant's request, action or condition,  or
  occurred with his consent; or
(b)  The people have shown good cause why such order of release should
  not be issued. Such good cause must consist of some compelling  fact  or
  circumstance  which  precluded  grand  jury action within the prescribed
  period or rendered the same against the interest of justice.
