Opinion of the Court by
Chief Justice CarrollAffirming.
In a contest over the will of Mary M. Schrodt, in the Jefferson circuit court, the grounds of contest, as they appear in the statement of appeal from the judgment of the county court probating the will, are that the instrument was “not the last will and testament of the said decedent because of want of testamentary capacity and be*459cause of undue influence,” and “that the said paper or writing is not the true last will and testament of said -decedent. ”
'On the first trial of the case the contestants relied entirely on the grounds of lack of testamentary capacity and undue influence, making no effort whatever to contest the paper on the ground that it was not duly executed or was not wholly in the handwriting of the testatrix, as it purported to he. With the issues thus made the case went to the jury on instructions confined to the questions of testamentary capacity and undue influence, and the jury found against the will.
From the judgment on the verdict an appeal was prosecuted by the propounders to this court, and in an opinion that may be found in 181 Ky. 174, this court held that there was no evidence to warrant the finding of the jury that the testatrix was lacking in testamentary capacity or that the execution of the will was procured by undue influence, and directed that “if upon another trial the evidence be substantially the same the trial court will direct the jury to return a verdict sustaining the will.”
After this and when the case came on for a second trial in the circuit court the contestants, although introducing evidence on the subjects of testamentary capacity and undue influence, brought into the case for the first time the issue that the will was not executed by the testatrix, but was in fact a forgery, and when the case went to the jury, the court being of the opinion that the evidence of testamentary capacity and undue influence wras substantially the same as on the first trial, took away from the jury, in obedience to the direction of this court, these issues and submitted to the jury the single question whether the will was wholly written by the testatrix and her name subscribed thereto by herself, instructing the jury that “if the jury shall believe from the evidence that the paper dated February 19, 1916, read in evidence in this ease and purporting-to be the last will and testament of Mary M. Schrodt, deceased, was wholly written by the said Mary M. Schrodt, and that the name of said Mary M. Schrodt was subscribed thereto by herself, then , the jury will find tfle paper to be the last will and testament of said Mary M. Schrodt, deceased.
“But unless the jury shall believe from the evidence that said paper dated February 19,1916, read in evidence in this case and purporting to be the last will and testament of Mary M. Schrodt, deceased, was wholly written *460by tbe said Mary M. Scbrodt, and that tbe name of' said Mary M. Scbrodt was subscribed thereto by herself, then the jury will find that said paper is not the last will and testament of Mary M. Schrodt, deceased. ’ ’
The jury again returned a verdict breaking the will upon the ground to which they were limited by the instruction, and from the judgment on the verdict the propounders have again appealed.
On this appeal it is insisted for the propounders, first, that the court committed error in instructing the jury that the'burden was on the propounders to show that the paper offered was written and subscribed by the testatrix herself; second, that the court erred in permitting the-contestants to introduce into the case the new issue referred to, and, third, that the verdict was flagrantly against the evidence.,
■Concerning the burden of proof: When the contestants challenge the paper offered, as not being the last will and testament of the 'testator, or, in other words, that it was not executed according to 'law, or if a holographic will that-it was not wholly in the handwriting of the testator and subscribed by him with his own name, the burden is on the'propounders to show that the paper was executed according to law, and, if purporting to have been written by the testator, that it was wholly written and subscribed with his own name by him, and this burden follows the propounders entirely through the case. But when the propounclers have first shown by their evidence in chief that the will was executed according, to law, or if a holographic will that it was written wholly by the testator and subscribed by him with his own name, then the burden shifts to the contestants to overcome this evidence and to show if they can that the will was not written and subscribed by the testator himself.
In Gernert v. Straffer’s Executor, 162 Ky. 605, the court said, in respect to the burden of proof: “So that it may now be regarded as a closed question that when the propounder's have proven the statutory execution of the will they may rest their case without then offering any evidence on the soundness of mind of the testator at the time he executed, the paper, unless on its face it shows that it is so irrational, or its provisions so inconsistent, or its structure, language or details so incompatible with soundness of mind as to make necessary the introduction of some evidence of mental capacity. When a paper of this character is offered by the propounders they should, *461in addition to proving its statutory execution, introduce some evidence of the soundness of the mind of the testator at the time of its execution.
“The propounders may, however, if they desire, introduce preliminary evidence of the soundness of mind of the testator, although this is not necessary except when the will itself falls within the description above referred to. When the propounders have shown the statutory execution of the paper, and also the soundness of mind of the testator when the appearance of the paper makes necessary evidence of this character, they may then rest their case, and the burden of proving that the testator was of unsound mind when he executed the paper, or that its execution was procured by undue influence, shifts to the contestants, and they must then introduce their evidence, and after they have concluded their evidence the propounders may then introduce further evidence in rebuttal or contradiction of the evidence offered by the contestants. ’ ’
The next question is, did the trial.court err in permitting the contestants on the return of the ease to introduce the new issue setting up that the paper offered as the last will and testament was not wholly in the handwriting of the testatrix or her name subscribed thereto by herself? In support of the contention that it did, reliance is had on the case of Davis v. McCorkle, 14 Bush 746, in which the court said: “Where a given matter becomes the subject of litigation in and adjudication by a court of competent jurisdiction the .court requires the parties to bring forward their whole case, and will not, except under special circumstances, permit the same parties to open the same subject of litigation in respect of a matter which might have been brought forward as part of the subject in contest, but which was not brought forward only because they have, from negligence, inadvertence, or even accident, omitted a part of their case. The plea of res judicata applies not only to the point upon which the court was required by the parties to form an opinion and pronounce judgment, but to every point which properly belonged to the subject of litigation, and which thé parties, exercising reasonable diligence, might have brought forward at the time. . . . Reason and authority alike demand that if on first appeal there is a question in the record which, if decided in favor of the appellee, would entitle him to an affirmance of the judgment in his favor, *462it is his duty to present it to the court, and if the appellee fails to present the question, or the court fails to decide it and reverses the judgment, on a subsequent appeal that question must be treated as having been decided adversely to the appellee in the first case, whether he be appellant or appellee on the subsequent appeal.” See also Miller’s Appellate Practice and Forms, section 138,.
And Goff v. Lowe, 141 Ky. 799, in which the court said: “When a case is brought here the opinion is conclusive of all questions either decided in the opinion or presented by the record and passed unnoticed in the opinion; for what the court passes unnoticed must be deemed to be ■approved. Were the rule otherwise litigation would be interminable, and reversals in cases of this sort- might be made without number, first upon one ground and then upon another. Such a practice would encourage, parties to present only some of the errors on one appeal and hold back the others- for service at a future time. The opinion on an appeal is the law of the case and is conclusive of all matters Then before the court.”.
But this well settled rule of practice is not, we think, . applicable to this case. On the first trial in the lower . court the only issues in the case made by the parties or . before the court related to the questions of testamentary capacity and undue influence, and these were the only issues and questions before this court when the case came here for review.. The issue as to whether the paper was wholly in the handwriting of the testatrix and subscribed by her with her own name was not before the trial court ■ on the first trial of the case, or in the record that came to this court.
So that the precise question now before us is: did the contestants, when the case went back for a new trial under the order of reversal, have the right to bring into the . case the new issue .which we have mentioned?
It is provided in section 134 of the Civil Code that ■ ‘ ‘ The court may, at any time, in furtherance of justice and on such terms as may be proper, cause or permit a pleading or proceeding to be amended by adding or striking out the name of a party, or by correcting a mistake in the name of a party, or a mistake in any other respect, or by inserting other allegations material to the case, or, if the amendment do not change substantially the claim or defense, by conforming the pleading or proceeding to the facts proved. And, if a proceeding taken by a party fail to conform in any respect to the provisions of this *463Code, the court may permit an amendment of such proceeding so.as to make it conformable thereto. And, if the allegations of a pleading be so indefinite or uncertain that the precise nature of the claim or defense is not apparent, the court may require the pleading to be made definite and certain-by amendment. The court must, in every stage of an action, disregard any error or defect in the proceedings which does not affect the substantial rights of the.adverse party; and no judgment shall be reversed or affected by reason of such error or defect. ’ ’
• And we think this section applies, to proceedings in the trial' court after a case has been sent back by this court for a retrial except in such particulars as. this, court may have directed the trial court how to • proceed. In other words, our understanding is that when a case goes back from this court for a new trial the situation of the parties and the condition of the case is the same .as if the trial court in place of this court had granted, a new trial, subject, however, to such directions as .this -court may have given concerning the manner in which the case shall be retried, and so. the action of the - trial court in permitting either of the parties to introduce into the case for the first time a new and material issue will not be interfered with by-this court unless it appears .that in so doing the trial court abused its broad discretion. Enc. Pleading and Practice, vol. 1, p. 489.
But the right of the trial court .to permit new issues to-be brought into the case after it has been sent back by this court for a retrial or when a new trial is granted should not be extended to the party who succeeds in obtaining a new trial or in securing a reversal with directions for a retrial unless it is made .to appear that the new issues sought by such party to be brought into the' case could not in the exercise of reasonable diligence on his part-have been put into the case on the first trial.
. If the -rule were otherwise litigation would be interminable and new trials o.r retrials-would be without number, first upon one ground and then upon. another, and parties would be encouraged to split up their rights of action or causes of defense, presenting only some of them in one trial while holding back the others for service at a' future time.,
This rule of practice,- however, should not be applied to the party who succeeds in the lower court and does not ask a new trial, or who loses in this court on the appeal of his adversary. If a new trial is granted in the lower *464court to the unsuccessful party there or he obtains a reversal in this court with directions for a retrial, the other party may in either event put into the case on the second trial new issues, and this without reference to whether by the exercise of reasonable diligence he could have put them in the case on or before.the first trial.
The reason why this distinction should be made and why the successful party in the lower court before a new trial is there granted or the unsuccessful party in this court when a retrial is ordered may be permitted to bring into the case new issues, is that his failure to do this in the first instance will not delay the final trial of the case or permit him by splitting up his cause of action or defense to extend the litigation. He is merely allowed to take advantage of a situation opened up to him over his objection.
When the parties go to trial in the circuit court each should put into the case every cause of action or defense that in the exercise of' reasonable diligence is available and that he desires to rely on, and the one failing to do this cannot, when a new trial or a retrial is secured on his motion, thereafter inject into the case a new issue that in the exercise of reasonable diligence , on his part might have been disposed of on the first trial.
Applying now to this case the rules of practice as we have stated them, our opinion is that the contestants had the right to put into the case on the second trial the new issue then first presented, although they could not have done this if the new trial had been granted on their motion.
The remaining question relates to the sufficiency of the evidence to sustain the- finding of the jury. Upon this point it would serve no useful purpose to extend this opinion by a recital of the evidence. It is • sufficient to say that there was evidence conducing to show that the paper was wholly in the handwriting of the testatrix and. that her name was subscribed by her. There was also evidence tending to show that the paper was a forgery or that it was not wholly written by her. On the facts the jury might have found either way, and it could not be said that their finding was flagrantly against the evidence.
Before ending the opinion we think it proper to say that upon a reconsideration Of this case in response to the petition for rehearing filed by appellant we have, reached the conclusion that the judgment appealed froin ■ was rightly affirmed, but the reasoning of the opinion on the *465subject of permitting new issues to be brought into tbe case was not correct or satisfactory. Accordingly, tbe opinion as banded down bas been reformed and a different rule laid down as to tbe circumstances under which new issues may be brought into tbe ease following a reversal with directions for a new trial.
Under rule 13, providing that opinions shall not be given out for publication until tbe petition for a rehearing is disposed of, we have adopted tbe practice of correcting and reforming tbe original opinion when necessary to correct errors pointed out in the petition for a rehearing, in place of banding down, as formerly was done, a separate response to tbe petition, and this new practice we have followed in this case.
Upon tbe whole case we see no reason for disturbing tbe judgment, and it is affirmed.
