This is an appeal from a denial by a judge of probate of a motion for the framing of issues for trial to a *254jury on a petition for the allowance of a will. The motion was heard and decided in the Probate Court on statements of counsel for the respective parties as to their expectation of evidence to be presented at a trial. These statements were taken stenographically and are reported in the record in lieu of evidence. This was proper practice in the discretion of the judge. No rulings of law are presented for examination. The motion simply was denied and an appeal taken.
The contention of the appellants is that the denial of their motion on their statement of expected evidence was so erroneous that it should be reversed and an order be entered framing issues.
The principles by which the Probate Court must be governed in reaching a decision on a motion for jury issues have recently been elaborated. Fuller v. Sylvia, 240 Mass. 49, 52, 53. Those principles were but an amplification of what had been declared in earlier decisions collected in that opinion. It would be vain to repeat or to restate them. They are reaffirmed. They must be the guide of probate judges in passing upon such motions as that here presented.
The function of this court in reviewing a decision made by the Probate Court on such a motion cannot readily be formulated in such words that it can be applied to the record of a statement of anticipated proof made by counsel with the same certainty as can standards of weights and measures to material substances. In general the practice on probate appeals to this court conforms to equity practice so far as practicable and applicable. Churchill v. Churchill, 239 Mass. 443, 445. In the recent case of Cook v. Mosher, 243 Mass. 149, reference was made, with adequate citation of authorities, to the differing practice prevailing in this court on the two classes of equity appeals, one with report of oral testimony and the other with report of evidence mainly documentary. That familiar difference need not be reéxplained. In the former class of cases this court examines the report of the evidence and reaches its own conclusion as to facts, but does not reverse a decision of a trial judge based on oral testimony unless plainly wrong, *255for the reason that he, having seen the witnesses face to face, is in a better position to pass upon their credibility and the weight to be attributed to their words than an appellate court only reading the printed page. In the latter class of cases nothing depends upon the weight and credibility of testimony given orally, and the appellate court stands where the trial court stood with respect to weighing evidence and drawing inferences. It was held in Cook v. Mosher that, while a case coming, as this case does, on appeal from a decision by a Probate Court based on statements of counsel as to expected proof, was nearly on the same footing as the latter class of cases, yet this court ordinarily will not reverse an order of a probate judge respecting the framing of issues. That implies that there is an element of discretion in the action of the probate judge. While cases of this kind are nearly like equity cases coming before this court on appeal where the evidence is documentary, they are not identical and precisely the same rules of law are not applicable. Likeness does not mean sameness nor import identity of governing principles. Houghton v. Field, 2 Cush. 141, 145. Bliss v. Bliss, 221 Mass. 201, 211. Decisions made by probate judges on statements of counsel as to expected evidence are not utterly disregarded by this court, when brought here on appeal. We do not' decide such a case wholly anew as if presented to us for the first time. Some weight is attributed to the decision of the probate judge. On the other hand, it is made the duty of the Probate Court by G. L. c. 215, § 16, to act upon application of parties for framing issues to a jury in will cases “ in accordance with the practice established by the Supreme Judicial Court in like cases.” That is a matter which in the nature of things cannot rest in the discretion of the Probate Court. It must be subject to the corrective determination of this court. Otherwise there could be no assurance of uniformity of practice in the several counties of the'Commonwealth, and great diversity of view might gain foothold in different parts of the State touching the practice established by this court while exercising exclusive jurisdiction of that subject, without any means for determining what that practice was. Therefore, *256decisions like McKay v. Kean, 167 Mass. 524, 526, to the effect that whether issues should be framed is a matter within the discretion of the court, are not strictly applicable. The function of this court in such appeals as described in Cook v. Mosher is as explicit as seems practicable at present. The weight to be given to the decision of the probate judge is that to which it seems entitled in the light of the whole record.
The statements of counsel in the case at bar present a close question on the point whether real and genuine questions of fact on the issues of soundness of mind of the decedent and of undue influence were made out. Fuller v. Sylvia, 240 Mass. 49. It would serve no useful purpose to narrate those statements. They were of such nature that we should not have been inclined to set aside an order granting those issues. We do not think the contrary decision ought to be reversed.
After decision had been rendered on the motion for framing of issues, motion for a rehearing of that motion was filed. Before the motion for rehearing came on to be heard, appeal from the decree denying jury issues was seasonably filed. G. L. c. 215, § 22. Thereafter, on hearing of the motion for rehearing, the judge ruled that consideration of that motion be continued until after decision bn the appeal. There was no error of law in this ruling. Hellier v. Loring, 242 Mass. 251, 254.
He also ruled in that connection that, after that appeal should be disposed of, he had the right to entertain and grant or deny a motion for rehearing. It is open to doubt whether such an anticipatory ruling may be reported even when made in connection with an interlocutory order. Agoos v. Cosmopolitan Trust Co. 241 Mass. 103. Without pausing to pass upon that question, we express our views on the ruling.
A motion for a rehearing of a motion to frame jury issues has no standing as matter of right. Nevertheless, it may be entertained if the judge thinks that it is required by justice. The court has power to reconsider its decision on the same facts, although this power is and ought to be exercised only *257rarely. The rendition of a judicial decision imports a settled conviction founded on deliberation, weighing of evidence, and investigation of law. While there may be “ trepidations of the balance,” there .ought to be no vacillation in the scales of justice. Nevertheless, there may arise a firm persuasion in the mind of a judge that error has been made and, if so, it should be corrected. Waucantuck Mills v. Magee Carpet Co. 225 Mass. 31, and cases there collected. Cinamon v. St. Louis Rubber Co. 229 Mass. 33, 37. Sallinger v. Hughes, 235 Mass. 104, 107. There is possibility of error by the most learned and painstaking of courts. Powers v. Sturtevant, 200 Mass. 519, 520. These principles are applicable to decisions concerning interlocutory matters before final decree or final judgment, while still within the control of the court.
A different rule is pertinent to the ruling here reported. Where a decision has come before the full court for review and correction, such a decision if affirmed must stand. There cannot be' further review of the same point in the light of the same evidence after a mandate from this court. It is the interest of the public that in. those conditions there be an end of litigation. The Probate Court must abide by the decision of this court in its further proceedings. Day v. Mills, 213 Mass. 585, and cases collected at page 587. Peoples National Bank v. Mulholland, 228 Mass. 152, 155. If the order of the Probate Court should not be affirmed, then it is conceivable that principles of law might be stated in the decision of this court which would render appropriate the consideration of a motion for a rehearing of the motion to frame issues. If, however, there is evidence, newly discovered since the denial of the motion to frame issues, of such importance as to have a material effect on the questioh to be determined, then there is jurisdiction for rehearing of the motion. But such newly discovered evidence ought to be so essential to a proper consideration of the motion as to be likely to affect the substantial interests of the parties. See West v. Platt, 124 Mass. 353, 355, and Berggren v. Mutual Life Ins. Co. of New York, 231 Mass. 173.
The ruling upon this point is distinguishable from that *258involved in Hellier v. Loring, 242 Mass. 251, where the original decision was held to have been made rightly ex parte and the motion for revocation implied a hearing on the merits.
Orders affirmed.
