Section 230.40. Removal of action; determinations and rulings before and after removal; by which courts made

Upon  any  removal of an indictment and action from one superior court
  to another pursuant to the provisions of  this  article,  determinations
  and  rulings with respect to the action made before such removal are not
  thereby rendered invalid.   All subsequent  determinations  and  rulings
  must  be  made  by  the  court  to which the action is removed; and such
  latter court is deemed  to  have  control  of  the  grand  jury  minutes
  underlying  the  indictment  for the purpose of determining post-removal
  motions addressed to the legal sufficiency of the grand jury evidence or
  the validity of the grand jury proceeding.
