Although the district court identified-the four Pioneer factors, it denied plaintiffs’ motion for relief from judgment after analyzing only their reason for the late filing. The court said nothing about the remaining three factors.
The district court may consider the Pioneer factors without discussing how much weight it gives to each. See Lemoge v. United States, 587 F.3d 1188, 1194 (9th Cir. 2009). But when the district court fails to discuss some of the factors, we must determine whether the omitted factors could reasonably support the district court’s conclusion. See Ahanchian v. Xenon Pictures, Inc., 624 F.3d 1253, 1258 (9th Cir. 2010); Bateman, 231 F.3d at 1224. Even giving the district court the benefit of the doubt, we can’t see how the balance of the Pioneer factors supports the district court’s decision.
First, defendants were not prejudiced by plaintiffs’ two-day delay in filing the SAC. We asked about this at oral argument, and counsel for . the school district’s only response was that judgment had been entered. Oral Arg. at 16:28-17:37, available at https://youtu.be/rp07S0u I-EI. Defendants may lose a “quick but unmerited victory,” but “we do not consider [this] prejudicial.” Ahanchian, 624 F.3d at 1262.
Second, the length of the delay and its potential impact on the proceedings were minimal. The delay was only for two days; we have found far longer delays excusable under Rule 60(b)(1). See, e.g., id. (three-day delay in filing an opposition to summary judgment); Bateman, 231 F.3d at 1223 (twelve-day delay in requesting a rescission of the summary judgment order and over a month-long delay in filing a Rule 60(b) motion). The two-day delay would not have changed the course of the proceedings. If. anything, it was the school district’s eagerness for a “gotcha” victory that has kept the case from advancing on the merits.
Third, there is no evidence that plaintiffs’ trial counsel concocted a “post-hoc rationalization ... to secure additional time,” Ahanchian, 624 F.3d at 1262, or otherwise acted with bad faith. A lack of familiarity with CM/ECF may be a poor excuse but it doesn’t show bad faith. See Lemoge, 587 F.3d at 1197 (finding'no bad faith where the “errors resulted from negligence and carelessness, not from deviousness -or-willfulness” (citation and internal quotation marks omitted)).
The question remains whether the single factor that the district court weighed against granting relief can by itself justify the district court’s decision. This is not a case where counsel’s neglect is so egregious that it outweighs the remaining three factors. Plaintiffs’ trial counsel simply misunderstood a docket entry and made a calendaring error of the type.that is sometimes committed even by sophisticated law firms. See, e.g., Pincay v. Andrews, 389 F.3d 853, 855, 858-60 (9th Cir. 2004) (en banc) (affirming the district court’s finding of excusable neglect where a sophisticated law firm made a calendaring error based on a paralegal’s misreading of Federal Rule of Appellate Procedure 4). Indeed, the court’s own clerk, who presumably deals with CM/ECF on a daily basis, committed a filing error and had to re-file the order two days later. If the trial counsel’s neglect here was not excusable, it’s hard to see when neglect would ever be excusable.
Because the district court’s decision cannot be supported by the record, we hold that it abused its discretion by denying plaintiffs relief from judgment under Rule 60(b)(1). Because we. reverse the district court’s denial of relief from judgment, we do not review the district court’s dismissal of the FAC.
