OPINION
{1 Cristobal and Elida Serrato (Serratos) appeal from the trial court's determination that they failed to comply with the notice of claim requirements of the Utah Governmental Immunity Act and that they cannot refile their claim under Utah Code Ann. § 70-12-40 (1996) (savings statute). The Utah Transit Authority (UTA) and Lance K. Sargent (Sargent) cross-aрpeal from the trial court's order granting the Serratos an extension of time to appeal.
BACKGROUND
T2 On December 17, 1996, the Serratos' truck and a UTA bus collided, injuring both Cristobal Serrato, who was driving, and his wife, Elida Serrato. The UTA bus was driven by Lance Sargent.
13 Settlement negotiations between the Serratos and the UTA ensued, but evеntually broke down. On December 8, 1997, the Ser-ratos filed a notice of claim for infury with Steven Cain, UTA Risk Manager, David Pitcher, UTA Claims Administrator, and Jan Graham, Utah Attorney General.
T 4 The Serratos subsequently filed a complaint against the UTA and Lance Sargent alleging negligence. The UTA and Mr. Sargent filed an answer, and, later, a motion for summary judgment based upon the Serratos' failure to timely serve a notice of claim upon the UTA's board of directors or any individual board member of the UTA. The Serratos filed a motion in opposition to summary judgment, as well as a cross-motion for summary judgment relying on the savings statute.
[5 On August 2, 1999, the trial court heard thе motions and granted summary judgment for the UTA based on the Serratos' failure to timely serve a notice of claim on UTA's *618 board of directors, and denied summary judgment for the Serratos based upon the savings statute. 1 The final judgment and order was entered on August 26, 1999. Pursuant to Rule 58A of the Utah Rules of Civil Procedure, counsel for the UTA mailed a Notice of Entry of Summary Judgment and Order of Dismissal dated August 31, 1999 to counsel for the Serratos, which read: "NOTICE is hereby given pursuant to Rule 58A(d) of the Utah Rules of Civil Procedure that the Summary Judgment and Order of Dismissal in the above-referenced matter was signed by the Honorable Stephen L. Henriod on August 26, 1999, and has been filed. Please govern yourselves accordingly." On October 1, 1999, the Serratos filed a motion to extend the time to appeal. The motion to extend was grounded upon the fact that the Serratos' counsel somehow assumed the date of the Rule 58A notice was the date of the entry of judgment. The trial court granted that motion by minute entry dated October 27, 1999, without oral argument, and entered an order extending the time to appeal until November 8, 1999. Although the motion and opposition thereto were supported by memoranda and affidavits, the minute entry did not contain findings of fact, conclusions of law, or any other indication of the reasoning of the court. The Serratos filed their notice of appeal on November 2, 1999. 2 The UTA filed its cross-appeal on November 15, 1999.
ISSUE AND STANDARD OF REVIEW
T6 Although there are three main issues raised in this appeal and cross-appeal, we address only the issue raised in the cross-appeal: whether the trial court abused its discretion by granting an extеnsion of time to appeal pursuant to Rule 4(e) of the Utah Rules of Appellate Procedure. The discretion of the trial court to grant or deny a Rule 4(e) motion is very broad, highly fact depen-dant, and fundamentally equitable in nature. See Reisbeck v. HCA Health Serv. of Utah, Inc.,
ANALYSIS
17 If an appeal is not timely filed, this court lacks jurisdiction to hear the appeаl. See State v. Montoya,
18 Here, the Serratos failed to file their appeal within the 80 days required by Rule 4(a) of the Utah Rules of Appellate Procedure. The Serratos never claimed, nor is there any factual support, that special circumstances existed beyond their cоntrol which caused the delay in filing the notice of appeal. The Serratos' attorney's justification for failing to meet the deadline for filing a notice of appeal is that he misread the Notice of Entry of Summary Judgment and Order of Dismissal and believed that the judgment had been entered on August 31, 1999 instead of August 26, 1999. Counsеl realized this mistake on September 30, 1999, after calling the court clerk, who informed him that the judgment was not entered on August 31, 1999. Counsel claims that he misread the Notice because it merely states that the order was "signed by the Honorable Stephen L. Henriod on August 26, 1999," and did not explicitly state that the order was entered by the clerk on August 26, 1999. Counsel does not explain how he misinterpreted the rest of that sentence which reads: "signed by the Honorable Stephen L. Henriod on August 26, 1999, and has been filed." (Emphasis added). 5 Counsel's failure is pure negligence on his part and, therefore, plaintiffs must show the negligence is excusable to justify an еxtension to appeal.
«19 The Utah Supreme Court adopted four non-exclusive factors "relevant to a determination of excusable neglect" in West v. Coates,
110 The latest Utah Supreme Court case addressing excusable neglect is Reisbеck v. HCA Health Services of Utah, Inc.,
«111 Here, the trial court еxceeded its discretion by granting the Serratos an extension to file their notice of appeal. Although the trial court has broad discretion to determine if a party's neglect is excusable, that discretion is not limitless. Here, the Serra-tos' attorney misread the Rule 58A Notice and then did nothing to check on his initial misinterpretation for almost thirty days. 9 Additionally, counsel did not merely overlook the mistake for four days, he failed to file the Notice of Appeal for thirty-four days. Although such deadlines are concededly arbitrary, they must be adhered to in order to prevent eases from continually lingering and to ensurе finality in the system.
$12 Additionally, under an equitable approach, it is unfair to allow an extension for what amounts to no excuse. See Prizevoits v. Indiana Bell Tel. Co.,
. That the four-part Pioneer standard fOr determining excusable neglect applies does not change existing law that a lawyer's misunderstanding of clear law cannot constitutе exeusable neglect. If it could, almost every appellant's lawyer would plead his own inability to understand the law when he fails to comply with the deadline. We do not believe that the Court intended a practice that would require courts to be that lenient about disobedience to plain law.
Advanced Estimating,
CONCLUSION
{ 13 The trial court exceeded its discretion in determining that counsel's misreading the date of the entry of judgment to be "exceusa-ble neglect." Our resolution of this appeal makes it unnecessary to address the merits of gps issues set forth in the Serratos' appeal. 'The Serratos' appeal is dismissed for lack of jurisdiction.

Notes
. Utah Code Ann. § 70-12-40 (1996).
. A notice of appeal is not a complex document. As is typical, the notice of appeal eventually filed in this case is a document consisting of a heading, two sentences, and date and signature lines.
. Appellants reference good cause in their brief in оnly one line. It stated: ""In addition, or in the alternative, the facts demonstrate 'good cause' for allowing the time to be extended." While this court may affirm the trial court on any proper grounds, see Otteson v. Dep't of Human Serv.,
. The entire rule reads:
Extension of time to appeal. The trial court, upon a showing of excusable neglect or good cause, may extend the time for filing a notice of appeal upon motion filed not later than 30 days after the expiration of the time prescribed *619 by paragraph (a) of this rule [within 30 days after the entry of the order]. A motion filed before expiration of the prescribed time may be ex parte unless the trial court otherwise requires. Notice of a motion filed after expiration of the prescribed time shall be given to the other parties in accordance with the rules of practice of the trial court. No extension shall exceed 30 days past the prescribed time or 10 days from the date of entry of the order granting the motion, whichever occurs later.
Utah R.App.P. 4(e).
. A reasonably prudent person would not misread such a straightforward impоrtant legal document. See Washington Fed. Sav. & Loan Ass'n v. Transamerica Premier Ins. Co.,
. The Utah Supreme Court also аddressed the issue of excusable neglect in an earlier opinion, Prowswood, Inc. v. Mountain Fuel Supply,
. In West, the court remanded for the trial court to determine if thеre was excusable neglect when the attorney failed to check the filing date with the court clerk in a timely manner due to the court's history of a six-month delay in issuing orders. See West v. Coates,
. See also David N. May, Pioneer's Paradox: Appellate Rule 4(a)(5) and the Rule Against Excusing Ignorance of Law, 48 Drake L.Rev. 677 (2000) for an analysis of rejecting excusable neglect based upon an attorney's mistake or ignorance of law post-Pioneer.
. Counsel suggests that his mistake is somehow more excusable because he chose to call the court clerk on September 30, 1999, some 29 days after the Notice of Judgment and 34 days after the entry thereof.
