OPINION
1 We granted interlocutory appeal to review the trial court's order (1) denying the plaintiffs' Motion for Enlargement of Time to designate expert witnesses and submit expert reports, and (2) excluding the plaintiffs' experts from testifying at trial as a sanction for failure to adhere to discovery deadlines. We reverse and remand.
BACKGROUND
T2 Plaintiffs Wayne L. Welsh and Carol Welsh (the Welshes) filed suit in February 2006 against Lakeview Hospital (Lakeview) claiming negligence and loss of consortium for injuries Mr. Welsh allegedly suffered while being treated there. Mr. Welsh sought treatment at Lakeview for temporary loss of consciousness, dizziness, and nausea. The Welshes allege that, during treatment, Mr. Welsh was left alone on an elevated examination table and fell. They further allege that, as a result, he suffered a fractured skull and a subdural hematoma and lapsed into a coma. Mr. Welsh underwent brain surgery and remained in a coma for several days. The Welshes allege that Mr. Welsh has suffered extensive brain damage, requiring significant continued medical care.
3 In August 2006, the trial court entered its first scheduling order. This scheduling order set deadlines for the completion of discovery, including designation of expert witnesses and submission of initial expert reports. By stipulation of the parties, the order was amended in May 2007 and again in February 2008 to allow more time for expert discovery. In June 2008, the Welshes' attorney, Nathan Wileox, moved from the firm of Anderson & Karrenberg to the firm of Clyde Snow & Sessions, taking this case with him. On September 10, 2008, the parties submitted a proposal to amend the scheduling order for a third time. The trial court initially denied it. But after a telephone conference on September 830, 2008, the trial court entered a third amended scheduling order. The order warned that the case would be dismissed if it did not move forward:
[The case is 2 1/2 years old and we have received the 4th scheduling order. The Court will dismiss this case if it doesn't start moving forward. If the Court doesn't see some action, it will notice the case for Pretrial and determine what has been done and if it isn't moving forward, the Court will dismiss the action.
¶4 This scheduling order required the Welshes to submit their initial expert reports and designations no later than December 1, 2008. On November 26, 2008, Matthew Steward and Rodney Snow of Clyde Snow & Sessions entered their appearances as new counsel for the Welshes. On the same day and despite the court's warning, they filed a motion seeking an enlargement of time until January 9, 2009, to submit expert reports and designations. That motion stated two grounds: (1) the Welshes had new counsel and (2) Lakeview had contributed to the delay in the case by not making its employees available for depositions. The motion did not seek to extend the deadlines for submission of rebuttal expert reports or completion of expert discovery, or to affect the scheduling of trial.
¶5 On December 1, 2008, Lakeview filed a motion for summary judgment, arguing that no experts had been timely designated and that without expert testimony the Welshes would be unable to establish a prima facie case of negligence. The trial court later denied this motion on the ground that although the Welshes could not call expert witnesses at trial, they could pursue a res ipsa loquitur theory of liability.
¶6 While these motions were pending, the Welshes submitted their expert designations. They designated three experts: (1) a certified physician to testify to the standard of care and its alleged violation by Lakeview; (2) a life care specialist to testify to Mr. Welsh's future injury-related expenses; and (8) a forensic accountant to testify to Mr. Welsh's economic loss as a result of the injury.
¶7 On December 29, 2009, the court clerk made the following entry on the court's docket: "[The Welshes'] Motion to Enlarge Time is granted, last time. He needs to submit an order. I called his office this date." Based on this phone call and docket entry, the Welshes submitted a proposed order extending their expert cutoff date to January 9, 2009. On January 9, 2009, the Welshes submitted their expert reports.
¶8 On January 22, 2009, nearly two weeks after the Welshes had submitted their expert reports, the trial court entered an order denying their motion for an enlargement. In addition, citing rule 37(b)(2) of the Utah Rules of Civil Procedure, the court barred any use of the Welshes' "belated expert discovery materials at trial" as a sanction for missing the December 1, 2008 deadline. The Welshes filed a Motion for Relief from this order. The trial court denied their motion in an order entered April 14, 2009. The April 14 order reaffirmed the court's earlier rulings and, for the first time, ruled that the Welshes' "failure to comply with the discovery order was willful in that the plaintiffs' failure to comply was not due to involuntary noncompliance." We granted review of this interlocutory order.
ISSUE AND STANDARD OF REVIEW
¶9 The Welshes contend that the trial court erred by denying their motion to extend the deadline and by excluding their experts from testifying. "Trial courts have broad discretion in managing the cases assigned to their courts." Posner v. Equity Title Ins. Agency, Inc.,
110 However, a trial court's discretion to exclude expert witness testimony is not absolute. "Excluding a witness from testifying is ... extreme in nature and ... should be employed only with caution and restraint." Berrelt v. Denver & Rio Grande W. RR.,
ANALYSIS
T11 The Welshes challenge the trial court's finding of willfulness on two grounds. They first argue that the trial court's reliance on its finding of willfulness is "improper" because the April 14 finding of willfulness was an "after-the-fact" justification for the sanction imposed by the court on January 22. They also argue that the facts do not support a finding of willfulness. Lakeview counters that the trial court need not make a finding of willfulness at all and that, in any event, the facts here demonstrate willfulness.
112 The willfulness standard in this context is low. Wilfulness has been interpreted to mean "any intentional failure as distinguished from involuntary noncompliance. No wrongful intent need be shown." Utah Dep't of Transp. v. Osguthorpe,
¶13 A number of factors separate this case from others of this type. First, this is not a case where the sanctioned party "assume[d] that the trial judge had some duty to allow [it] to violate the discovery orders for any or no reason." DeBry v. Cascade Enters.,
T 14 In addition, the Welshes did not simply ignore the trial court's scheduling order; they moved to amend it. They moved before December 1 to extend the December 1 expert cutoff date. See generally Arnold v.
{15 Moreover, the Welshes motion did not seek to extend the deadline for completion of expert discovery or the certification of readiness for trial. Those deadlines remained unaffected by their motion. The purpose of requiring parties to disclose witnesses by a certain date is to allow the lawsuit to proceed in an orderly way and to avoid unnecessary trial delays. See Turner v. Nelson,
T16 Significantly, Lakeview has never claimed that granting the Welshes' motion would result in prejudice. In fact, Lakeview questions whether prejudice is even a relevant consideration. While rule 37 does not expressly mention prejudice, cases from the supreme court and this court treat it as a relevant consideration. See, eg., DeBry,
17 While Lakeview will suffer no prejudice if the Welshes' experts are allowed to testify at trial, the prejudice to the Welshes if their experts are excluded is potentially devastating. Indeed, once the December 1 deadline passed without the Welshes' having designated their experts, Lakeview filed a motion for summary judgment on the ground that "[iln the absence of expert testimony, the Court must presume that Lakeview complied with the standard of care and did not cause any injury." In other words, according to Lakeview, expert witnesses were essential to the Welshes' case. The trial court denied the summary judgment motion on the ground that the Welshes could proceed to trial on a res ipsa loquitur theory of liability. But to prevail at trial, the Welshes must establish damages as well as liability. See White v. Blackburn,
¶19 In sum, the trial court's discretion, while expansive, see Morton v. Continental Baking Co.,
CONCLUSION
120 Accordingly, the order of the trial court is reversed and the case remanded for further proceedings.
T 21 WE CONCUR: JAMES Z. DAVIS, Presiding Judge, and WILLIAM A. THORNE JR., Judge.
