This is an action of trespass, brought March 26, 1907, by John R. Forrest to recover damages for injuries which he sustained by reason of the alleged negligence of the defendant company, in July, 1906. The statement was filed, a rule to plead was granted June 3, 1907, and on June 17th the defendant pleaded “not guilty.” The plaintiff, died November 2, 1907, and in October, 1915, his death was suggested, and June 5,1916, his death was again suggested of record and Indiana Forrest, his administratrix, was substituted as plaintiff. In the statement the plaintiff averred that the defendant’s car had stopped to receive passengers, and, when he was attempting to board it, it prematurely started, throwing him tq the ground *386and causing him severe injuries. The defendant denied that the car stopped and claims that it was in motion when plaintiff attempted to board it. This was the issue of fact between the parties. The trial resulted in a verdict for the plaintiff. Judgment having been entered on the verdict, the defendant has appealed.

The substituted plaintiff offered in evidence at the trial the letters of administration granted her, which offer was objected to by the defendant on the ground that it was too late to maintain the action, in other words, that the suit was abated by delay in its prosecution. The-objection was overruled and the evidence admitted. Defendant contends that as an action for death must be brought within one year after the death and an action for personal injuries within two years, under the statutes, the right to- substitute the personal representative and prosecute the action should be limited to- one year after the death of the injured party. The conclusive reply to this argument is that no act of assembly by direct provision or even by inference requires the substitution of the personal representative to be made within one year succeeding the injured person’s death. It is a matter solely within the discretion of the legislature, and hence the courts cannot establish such limitation by construction of the statutes dealing with the subject. Section 18 of the Act of April 15, 1851, P. L. 674, authorizing the substitution, simply provides that no such action “shall abate by reason of the death of the plaintiff, but the personal representatives of the deceased may be substituted as plaintiff and prosecute the suit to final judgment and satisfaction.” It will be observed that no time within which the substitution shall be made is fixed by the statute, and it is. clear that we cannot and should not, as claimed by the appellant, invade the exclusive province of the legislature and do so by construction.

We do not regard the present case as. ruled in appellant’s favor by Waring Bros. & Co. v. Pennsylvania Railroad Company, 176 Pa. 172. There, tke summons, was; *387issued in 1879, and no further steps were taken in the prosecution of the case until 1894 when plaintiffs filed a statement and affidavit of claim which showed that the cause of action had originated in November, 1873, about twenty-one years prior to filing the statement. The court made absolute the defendant’s rule to strike off the statement and affidavit and entered judgment of non pros, because of the laches of the plaintiffs in proceeding with the cause. We sustained this action of the Common Pleas, holding “the judgment was within the power and discretion of the court below and it will not be reviewed.” The ground of this decision is stated in the concluding-part of the opinion of Green, J., as follows (p. 180) : “We decide this case upon the undoubted power of the court below to make the rule of practice relating to this subject, and upon the necessarily implied power to grant the same relief upon motion and hearing, which the defendant could have had by the mere act of its counsel in directing the prothonotary to enter a non pros, at any time after three months; and also upon the further consideration that in any event, and in the best aspect of the case for the plaintiffs, the matter was within the discretion of the learned court below, and in the exercise of that discretion the decision was against the plaintiffs.”

In the subsequent case of Hillside Coal & Iron Co. v. Heermans et al., 191 Pa. 116, this court sustained the court below in refusing to grant a judgment of non pros, on the ground of laches in prosecuting the action which was brought in 1881 and the motion for the judgment was made in 1898 by defendant who had held by adverse possession since 1872. In explaining and distinguishing the Waring case Green, J., who wrote the opinions in both cases, said, intér alia, in the later case (p. 118) : “That action however was a personal action......It was also the fact that after the issue and service of the writ of summons no further step had been taken until nearly fifteen years later when for' the first time the *388plaintiff filed a statement and affidavit of claim. So that, in point of fact, while the summons was issued in November, 1879, no statement of the plaintiff’s claim and no narr was filed until October, 1894. There was nothing on the record during all that time which informed the defendant as to what was the cause of action. When the statement was filed it appeared that the cause of action arose in 1873, which was nearly twenty-one years before the statement was filed. In these circumstances and for the reasons appearing in the opinion we sustained the nonsuit granted by the court below. In the present case none of these features is found except the period of delay......Defendants were immediately apprised by the writ of summons, which was served upon them, as to the exact character of the demand made upon them......The granting of a nonsuit for such a cause as this is a matter within the discretion of the court to which the application is made. We attached importance to that feature in the Waring case, supra, and think we should do so here. There was certainly no abuse of discretion in refusing the nonsuit in this case, on the contrary, we think the discretion of the court was wisely exercised in the rejection of the applicátion.”

i Most of the features of the Heermans case distinguishing it from the Waring case are to be found in the present case. Here, Forrest was injured in July, 1906, the action was brought in March, 1907, the statement of claim was filed June 3d, and a plea was entered June 17, 1907. It is true that the plaintiff’s death was not suggested until about eight and a half years after the suit was brought, but during all that time the defendant was fully apprised, by the record, of the cause of action, and could prepare to meet it. Either party could have listed the cause for trial. In the Waring case the statement was not filed until fifteen years after the summons was issued, and it was nearly twenty-one years after the cause of action originated until it appeared on the record, and in the meantime, so far as the record disclosed. *389the defendant was ignorant of the cause of action and hence could not prepare his defense. The usual and proper practice, as appears by the reported cases on the subject, where unreasonable, delay or laches is urged as the ground for abatement of the suit, is a motion or rulé taken by defendant, and not objection to testimony on-the trial of the cause. The defendant can and may waive the default or laches in the prosecution of the action and go to .trial on the merits, and it is not too much to assume that he does so where he takes no steps to abate the action until the plaintiff has incurred the expense of the preparation of the trial and the causé is before the court and jury for hearing and determination. Promptness by both parties in asserting their legal rights is expected and should be required. If at any time the defendant company in the present case thought the action had been abandoned, it should have pursued the established practice and moved the court or taken a rule to abate it, and not sought to accomplish that result by waiting until the case was listed for trial and was being heard by the court on its merits.

We think there is a clear and controlling distinction between the facts of the Waring case and the case at bar, and we think the court did not commit error in admitting in evidence the letters of administration granted the substituted plaintiff, and declining to hold that the action was abated by undue delay in its prosecution.

It is contended by appellant that, if the question considered above is ruled in favor of the appellee, the case should be reversed with a venire for errors committed by the court on the trial of the cause. We agree with the appellant that the case was for the jury. There was but a single witness produced on either side who saw the accident. The plaintiff’s witness testified that the car was at rest when the deceased attempted to enter it, and the witness for the defendant testified that it was in motion. In further contradiction of the plaintiff’s witness the defendant introduced statements made by the deceased *390and his witness that the car did not stop but was in motion at the time the deceased attempted to board it. The credibility of the witnesses was clearly for the jury, and the court was required to submit it.

We think the learned judge below erred in that part of his charge wherein, referring to the statement of Forrest, he said that “he [Forrest] did, ten months and thirteen days afterward, swear to another paper, which he signed by making his mark, that paper being the statement of claim in this case in which he swore that the car was standing still.” This, as is apparent, was most prejudicial to the defendant, and was directing the attention of the jury to evidence that had not been offered and was not before them; and, so far as the record discloses, the plaintiff had not adverted to the affidavit as evidence contradicting the statement of the deceased and in support of her claim. Whether the statement of claim would have been competent if offered for the purpose of contradicting the statement of the deceased is not before us and need not be decided.

The appellee has not pointed out and, so far as we can ■ ascertain from the record, there is no evidence that the affidavit and signature of the deceased to the statement were procured by fraud, coercion, or undue influence, and hence the eighth assignment of error must be sustained. Without referring to the several assignments, we have considered the controlling questions in the case, and, for the reasons stated, the judgment is reversed with a venire facias de novo.
