Art. 538. Effect of sustaining motion to quash
The court shall order the defendant discharged from custody or bail, as to that charge, when it sustains a motion to quash based upon the ground that:
(1) The offense is not punishable under a valid statute;
(2) Trial for the offense charged would constitute double jeopardy;
(3) The time limitation for the institution of prosecution or for the commencement of trial has expired; or
(4) The court has no jurisdiction of the offense charged.
In other cases, when a motion to quash is sustained, the court may order that the defendant be held in custody or that his bail be continued for a specified time, pending the filing of a new indictment.
