ON PETITION FOR REHEARING
Before GRAY, C. J., and McINTYRE, PARKER, and McEWAN, JJ. PER CURIAM.Defendant has petitioned this court for a rehearing of his appeal, claiming that from the decision of the court in Elmer v. State, Wyo., 463 P.2d 14, two elemental rights of the defendant have been invaded and vitiated: (1) to have untampered-with witnesses testify on his behalf and (2) to have a jury decide his case without any influence whatsoever on it except the consideration of the facts adduced at the trial and the application to those facts of the law as given by the judge in his instructions at the conclusion of the case. Relative to the challenged instruction defendant now says that “we have here a case in which the jury deliberated for nearly twelve hours and then at the jury’s initiative, and not at the judge’s as the opinion indicates, returned to the courtroom to report themselves hopelessly deadlocked and requested to be discharged * * *. What happened was that the presiding judge, counsel, and the parties were at their homes when telephoned by the bailiff to inform them that the jury had requested to report.”
Naturally, we are aware of the common lament that the filing of a petition for rehearing is quixotic or an exercise in futility. Although such plaint is not always without foundation, the reasons for non-*376success need to be faced. Sometimes it springs from the court’s lack of proper analysis or even from perverseness, but more often a petition is sponsored in the overenthusiasm of appellant’s counsel, whose solicitude for the client accounts for a procrustean approach in the appeal, accelerated by the time request for rehearing is made.
Rule 14, Rules of the Supreme Court, does not specify the grounds upon which a rehearing will be granted, and this is true in most jurisdictions,1 but it is basic that a rehearing will not be allowed merely for the purpose of reargument unless there is a reasonable probability that the court may have arrived at an erroneous conclusion or overlooked some important question or matter necessary to a correct decision. Moreover, we have often stated the circumstances under which rehearings will not be granted; and it is definitely established that where all the facts presented have been duly considered by the court and the application presents no new facts but simply reiterates the arguments made on the hearing, and is in effect an appeal to the court to review its decision on points and authorities already determined, a rehearing will be refused. Olds v. Hosford, Wyo., 354 P.2d 947, 359 P.2d 406; Braten v. Baker, 78 Wyo. 273, 323 P.2d 929, 325 P.2d 880.
The two grounds presented in this application for rehearing, the claimed impropriety of interviewing witnesses and the giving of the instruction, are premised entirely on the view that the trial court’s action in each instance was erroneous. Such is inconsistent with our opinion, which stated clearly that they were not erroneous and in detail explained the reasons for the holdings. As to the events which happened in the trial court immediately preceding the giving of the instruction now challenged, the transcript of the trial proceedings covering the time when the jury appeared before the court shows none of the occurrences which counsel now by aliunde statement would have us take into account. Even the affidavit of the juror, Mrs. Pen-ton, filed after the verdict and judgment and designed to impeach them, does not show that the jury reported to the court that they were deadlocked. It is elementary that matters not appearing in the record cannot be considered on appeal. Braten v. Baker, supra, 325 P.2d 880. Accordingly, the petition for rehearing must be denied.
Denied.
