McFarlin was indicted at the September term, 1904, of Coweta superior court. He filed a plea in abatement, on the ground that under the act approved August 15, 1903 (Acts 1903, p. 83), three of the grand jurors by whom the indictment *330was returned were ineligible, because they had previously served as grand jurors at the March term, 1904, of Coweta superior court; that no warrant had been issued for his arrest; that no bond had been given by him to appear at court; that he had no notice or knowledge that the grand jury at the September term would attempt to indict or would indict him; that he had had no prior opportunity to challenge the ineligible grand jurors; and that his plea was filed at the first opportunity he had for making this objection. There is no written demurrer or traverse in the record. It is, however, recited that this “ plea having been filed and argued, the same is hereby overruled.”
We can not, of course, consider statements of what occurred at the hearing, made in the briefs of both counsel, but which are not included in the judge’s certificate. No traverse having been filed, and the record failing to show that the case was submitted, as in Wells v. State, 118 Ga. 556 (7), to the judge without a jury, and it not appearing that the case was heard by him or the jury on evidence, we are forced to conclude that the plea was stricken, on motion, as being insufficient.
It is always necessary that challenges to jurors should be in due time, or else there will be a conclusive presumption that the want of qualification has been waived by all concerned. Jordan v. State, 119 Ga. 443. But here the plea avers that the defendant had no knowledge, or reason to believe, that any bill of indictment would be presented to the grand jury. , It sets out facts excusing his non-action, and meets the requirements suggested in Lascelles v. State, 90 Ga. 372. The plea, therefore, was not filed too late. The three grand jurors were incompetent to serve at the September term, 1904, if in truth they had served at the March term, 1904. The plea was therefore good in substance, and, upon proof of the facts charged, the indictment should have been quashed or abated.
The language of the statute and the public policy to be sub-served apply as well to grand as to petit jurors. It is intended as a relief, and to equalize jury duty. But it is also intended to prevent the same persons from constantly serving, whether they wish to or not. One grand jury may return no bill. 'Grand •juries are charged with ma'ny important public duties. The same facts in both classes of subjects may come before the succeeding *331body, and the public is entitled to a complete change of membership from term to term. Such is the language of the law; and where the objection is seasonably made, advantage 'can be taken of the fact that the body has not been duly constituted.
