delivered the opinion of the Court:

This action was brought to recover for damages claimed to have been sustained by plaintiff by being forcibly ejected from an omnibus controlled and operated by defendant in Chicago. There have been several trials, in the Superior and Appellate courts. On the last trial the jury found, and the court rendered a judgment, against defendant for $2600, and the case comes to this court by appeal from th'e Appellate Court for the First District.

The “People’s Omnibus and Baggage Line” was organized and became a corporation in 1871, and before the injury of which complaint is made. The horses and omnibus belonged to, and the driver was employed by, the company. Appellant was the president of the company, and was sued individually in this action, and was held liable for the injury.

The law conferred on appellee the right to travel in the omnibus, and if he, in the exercise of that right, was injured by the order of appellant, the latter is liable to respond for the injury in damages. The fact that appellant was th,e president of the corporation is no protection to him in the commission of an illegal act, and where an officer of an incorporation performs an illegal act resulting in an injury to another, he is liable. Nor does it exonerate him from such liability because the corporation may also be liable. The only question, therefore, is, did appellant give the order to the drivers of omnibuses of the company to exclude colored persons from traveling therein? That is a question of fact that was submitted to a jury, and they found appellant gave the general order tinder which appellee was expelled and injured by the driver. The Appellate Court have, by affirming the judgment, approved of the finding, and we are precluded from reviewing the evidence on that question. There being no semblance of authority to justify the promulgation of such an order, appellant was properly held liable on proof of the fact, unless the trial court has committed some error as to the law in trying the case. We will proceed to determine whether any such error was committed.

It is urged that the court erred in permitting evidence to he introduced that appellant was a stockholder in the corporation, that he and his brothers held a majority of the stock, and to inquire as to their disposition of the stock. This was clearly irrelevant to the issue, as whether they were stockholders, or not, was wholly immaterial. Appellant was the president of the company, and if he had control of its management and the direction of its affairs, it was wholly immaterial whether he owned its stock, or what amount, or what he did with it. But notwithstanding the evidence in question was irrelevant, we are unable to perceive how it could have prejudiced appellant before the jury. If we were to reverse in every case where immaterial evidence is admitted, but few judgments would ever be sustained. It‘is only when we can see that the admission of such evidence worked, "or probably did work, an injury to the party complaining, that we reverse.

There is an objection that the court erred in admitting the evidence of Young and Collins, who were drivers for the company at that time, that they had received from the assistant superintendent orders not to permit colored persons to ride in their omnibuses. If they received such orders, it was from a superior officer in the management of the affairs of the corporation. It may be it was inadmissible under the strict rules of evidence, but it was, under the circumstances of this case, irrelevant, and could have done no harm.

It is also urged that the court erred in admitting evidence that the driver was retained in the employment of the company after appellee was injured. Such evidence has been held admissible, when the fact was known to the officer or agent of the company having power to discharge the negligent servant, as characterizing the animus of those controlling the company, and as an ingredient in the measure of the damages. Inasmuch as we are precluded from considering the evidence, we must hold there is no error for which the judgment of the Appellate Court should be disturbed, and it is affirmed.

Judgment affirmed.

Mr. Chief Justice Scholfield: I do not concur in this opinion.
