ON PETITION EOR REI-IEARING.
Potter, Justice.The proceeding in error in this case was ordered dismissed on motion of the Attorney General for the failure of the plaintiff in error to file and serve briefs within the time required by the rules of this court. Counsel for plaintiff in error have filed a petition for rehearing. The facts upon which the motion was decided are stated in the former opinion. (124 Pac. 764.) Notwithstanding the rule of court requiring the plaintiff in error in both civil and criminal causes to file and serve his briefs within sixty days after filing his petition in error, more than six months was allowed to intervene between the time of filing the petition in error in this cause and the filing and serving of the briefs *491of plaintiff in error, and such briefs were not filed or served until nearly five months after the original-papers, including the bill of exceptions, and the transcript of the journal entries had been filed. No order was made extending the time for filing and serving briefs, nor was any application made for such an order, although ample provision therefor is made by the rules. On March 9, 1912, more than four months after the bill of exceptions was filed, a motion was filed in this court for the correction of the bill by having incorporated therein or identified as part thereof certain books of account that had been introduced in evidence upon the trial of the cause and referred to and marked as exhibits, the bill showing that such exhibits were not embraced therein. Upon the showing made by the affidavit of the leading counsel for plaintiff in error as to his understanding when the bill was presented to the trial judge that those exhibits were to be attached to or identified as a part of the bill before the allowance and signing of the same, the bill was ordered returned to the trial court for the purpose of allowing counsel to take such proceedings as might be deemed necessary or proper to have it amended or corrected so as to show such exhibits. It was subsequently returned to this court with a certified copy of an order of the trial court denying the motion and application of the plaintiff in error to amend or correct the bill, it being recited in such order that the. exhibits aforesaid were not in the bill when the-same was presented on the 4th day of September, 1911, nor then presented to the court to be incorporated in or identified as part of the bill, and that no application was then made for the withdrawal of the bill for the purpose of such incorporation or identification, but that such application was for the first time brought to the attention of said court after the return of the bill from this court, and that no good cause had been shown for the delay in making such application.
Although it was argued by counsel for plaintiff in error, and stated in the motion filed March 9, 1912, that the brief *492had been printed and was ready for filing, but that it was not then filed for the reason that counsel understood that filing and serving briefs would waive the right to apply for a correction of the bill, yet it appeared by the motion that counsel discovered the condition of the bill on the 20th day of January, 1912. And in view of the facts found by the trial court as to the presentation of the bill, .no good cause was or is shown, even if that would be material in the interest of the plaintiff in error, for the failure of counsel to know the condition of the bill when it was signed and filed in the trial court, viz: September 4, 1911, or on October 28, 1911, when it was filed in this court. But, as indicated in the former opinion, if there existed any good reason for delay in filing and serving briefs, counsel might have applied for, and doubtless would have obtained, an order extending the time. If the court should in this case, upon the facts and the showing made, overlook or excuse the violation of the rules respecting the filing and serving of briefs, it would amount to a declaration that such rules need not be observed by any party and are not to be enforced, and it would result in greatly delaying the business of the court and the administration of justice both in civil and criminal causes.
In the brief filed in support of the petition for rehearing it is argued that a brief is not due until the record is complete or agreed upon. That is .not the effect of any statute regulating appellate procedure in this court, nor of any rule of the court. It is the duty of counsel representing a plaintiff in error to prepare and present to the trial court a proper bill of exceptions if one is necessary, and if the’ bill is incomplete or cannot be procured or filed before the expiration of the time for filing briefs, without fault on the part of plaintiff in error or his counsel, he can be protected by a timely application for an extension of time upon a proper showing, where the appellate proceeding has been commenced in this court. It is also argued that by accepting service of the brief of plaintiff in error the Attorney *493General waived the failure to file-and serve the same within the time required by the rules. There is nothing in the record showing such acceptance of the brief. But merely accepting or acknowledging service of the brief would not •constitute such a waiver. Its only effect would be to render proof of service unnecessary. 'Nor can the further point made be sustained that the failure to file and serve briefs in time was waived by stating in the motion to dismiss as one of the grounds thereof that the bill of exceptions was insufficient for the reason that it does not purport to contain all the evidence. The fact that the motion to dismiss was not filed until after the filing of the briefs is not a waiver of the non-compliance with the rules, and is not sufficient to justify a denial of the motion. (Cronkhite v. Bothwell, 3 Wyo. 739, 31 Pac. 400.)
We have thus considered the additional points made by the petition for rehearing and the brief in support thereof. It is not an agreeable duty of the court to dismiss this or any cause for a failure to comply with the rules of procedure whether such rules are expressly prescribed by statute, or by the court under the authority conferred by statute. The could would much prefer, if that might properly be done, to allow the case to be heard upon its merits. But reasonable rules of procedure in appellate courts as well as in courts of •original jurisdiction are not unconstitutional, but are necessary to avoid unreasonable delays, as well as for ’the purpose of an orderly and intelligent presentation of a cause for determination. Remaining convinced that the motion, to dismiss was properly sustained, we perceive no reason to Relieve that a different result might follow a rehearing, and we therefore feel constrained to deny it. Rehearing denied.
