2. Where a motion to quash the indictment on the ground that defendant had not been granted a demanded commitment hearing (see Whitus v. State, 222 Ga. 116, 117 (3) ( 149 S.E.2d 138); distinguishing Manor v. State, 221 Ga. 866 ( 148 S.E.2d 305)) is overruled, such action of the trial judge will be affirmed in the absence of a showing that such demand was made. The mere statement of a fact in a motion is not proof of the fact.
