Certiorari to the Springfield Court of Appeals to review the record of that court in the case of Susie E. Kerr against Bush, Receiver of the St. Louis, Iron Mountain & Southern Railway Company for damages for the killing of her husband through the negligence of that company. Upon a trial before a jury a verdict was rendered in her favor in the sum of $3500. From this finding an appeal was perfected to the Springfield Court of Appeals, which affirmed the judgment of the trial court (
*602
The court, after reviewing the testimony at length, states “that there is neither any presumption nor any evidence on which to base a finding that the deceased approached the crossing where he was killed along the dirt road and not along the railroad.” Following this conclusion the court adds “that if defendant’s liability is to rest on the finding’ that the deceased approached the crossing along the public road, then to sustain such verdict would be violative of the rule that where the injury may with equal or greater probability have resulted from a different cause for which the defendant is not liable, then the verdict cannot stand; for it devolves on the plaintiff to prove with reasonable certainty that the cause for which the defendant is liable produced the result and this cannot be left to conjecture” (citing cases).
It is evident, therefore, that the specific nature of relator’s contention as to a variance between the theory of the trial court and the Court of Appeals consists in their respective findings as to the manner in which - the deceased approached the crossing. This difference to avail the defendant must he of. such a *603 nature as to constitute an essential factor in determining defendant’s liability. A mere difference in findings not so determinative will not authorize a ruling adverse to the judgment. This in no wise militates against the well established rule that if an injury may have resulted from one of two causes for* one of which and not the other the defendant is liable, the plaintiff must show' with reasonable certainty that the cause for which the defendant is liable produced the result, and if the evidence leaves it to conjecture the defendant is not liable.
To this effect and no further is our ruling in Degonia v. Railroad,
In Henry County v. Citizens Bank,
In Deschner v. Railroad,
In McGrath v. St. Louis Tr. Co.,
In Chinn v. Naylor,
In Meyer Bros. Drug Co. v. Bybee,

In Mirrielees v. Railroad,
' From these cases, relied upon by relator, and many . others which might be cited to the same effect, it appears that the difference in theory between the trial of a case • and its review and disposition upon appeal must, to authorize the invoking of the rule, involve a matter essential to the rendition of the judgment. The correctness of this conclusion is rendered more apparent when we consider the province of an appellate court, which is that of review. Such review is for the purpose of ascertaining if the real matters in issue were tried without error. Other than this the court has no concern because the trial court’s ruling, upon an immaterial matter is not error (Lesser Cot. Co. v. Railroad,
*605 It remains to be determined, therefore, whether the diverse findings of the trial court and the Court of Appeals in regard to the manner in which the deceased approached the crossing is of such a nature as to bring the case within the rule of a difference in theory between the trial and the appellate-court. The Court of Appeals-holds that if defendant’s liability is to rest upon the finding of the trial court in this regard the verdict cannot stand. Considered alone this is an unqualified holding of non-liability under the facts stated. But construed with reference to the nature of the facts found and in connection with the court’s subsequent language and its disposition of the case upon issues essential to a recovery it cannot be held to be a determinative ruling upon a matter at issue.
While it is true,- as stated by the Court of Appeals, that “it devolves upon a plaintiff' to prove with reasonable certainty that the cause for which a defendant is liable produced the result,” the manner of the approach of the deceased to- the crossing had no relation to or connection with the cause which resulted in his death. This cause was the manner in which the defendant’s train approached the crossing. The duty of the defendant was to give some effective warning to free itself from a charge of negligence, taking into consideration the physical location, at the time, of the deceased and his
status
towards the defendant due to said location. Tbe evidence discloses that he was on the public crossing when struck by defendant’s train. Thus located, he was not a trespasser, and this is true so far as concerns the liability of the defendant, regardless of the manner in which the deceased approached the crossing; this conclusion accords with reason and is in harmony with our ruling in the recent case of Torrance v. Pryor,
This case fixes the status of the person injured as a non-trespasser and as a consequence defines the conditions of defendant’s liability. In so holding, the immateriality of the fact as to the manner in which the injured party reached the highway is clearly indicated. Being immaterial, it is not an issue. Not being an issue it cannot be held to constitute a theory upon which the case was tried and hence the relator’s contention must be overruled.
This excerpt is sufficient to show that in this regard there was a material difference in the testimony at the two trials. Under such circumstances the doctrine as to the binding force of a former ruling cannot be effectively invoked. A review of the cases on this subject is conjfikmatory of this conclusion. [State v. Powell,
“On an examination of the entire record, we find that the case was actually tried and determined on this theory. The real issue presented and tried was whether any signals were given or any effective warning sound made by this train in approaching and passing' this crossing and whether any conspicuous light was being displayed, the dark and stormy condition being practically conceded. The evidence is such that the jury must have found either that the full statutory signals were given by this train or that no warning signals whatever were given; that either the headlight was burning as usual or that no light was displayed. No middle ground was presented. Under the evidence and instructions, the jury could have acquitted the deceased of contributory negligence only by finding that this *609 train approached this- crossing and struct deceased thereon without any sufficient warning by sound or whistle to apprise him in the exercise of due care of its approach.
“Such, also, are the issues presented by the pleadings taken as a whole, for, while the petition counts on the failure to give the statutory signals, the reply is :
‘ ‘ ‘ The plaintiff for her reply denies that her husband could have seen or heard the train prior to going upon the track, because the night was very dark and the engine drawing said train was running without a light upon the front end and that a car was attached to the front end of said engine and was being pushed in front of said engine; that no signal whatever was given; no light upon said engine; therefore, owing to the conditions aforesaid, her husband had no warning of the approach of said train.’
“The defendant was therefore fully informed of the exact facts which plaintiff intended to prove and which plaintiff’s evidence as believed by the jury did prove. It is also true that, while plaintiff’s instructions predicate liability on failure to give the arbitrary statutory signals by bell or whistle on approaching this crossing, yet to so find under' the evidence necessarily was to find that no signals or warning whatever were given; and by defendant’s instruction on contributory negligence the finding must have been for defendant if -the deceased could by using due care in looking and listening have discovered the coming train in time to have avoided being struck by it. ’ ’
That the reply, therefore, either at the trial or upon appeal, had or wals, attempted to be given any other office than to inform the defendant of the facts which plaintiff intended to prove in rebuttal of the plea of contributory negligence, is not apparent from the record.
The plaintiff’s right of recovery having; been limited to the cause of action stated in her petition and the triers of the facts having, under proper instructions, so found, there is no- substantial merit in this contention.

As 'a consequence the following cases: Mathieson v. Railroad,
Finding no contravention in the opinion of the Court of Appeals with the last previous rulings of this court, there exists no ground for our interference with the judgment and our writ is therefore quashed-
