considering imposing monetary sanctions upon both Wilson-Simmons and her attorneys.
“It is within the discretion of the district court to determine whether an evi-dentiary hearing would assist the court in its decision.” Id. The magistrate judge reviewed Wilson-Simmons’ entire 361 page deposition testimony in preparing his report and recommendation. The district court had before it the magistrate judge’s report and recommendation, the Appellants’ brief in opposition and response to the show cause order, and the court’s opinion granting summary judgment. The district court was familiar with the Plaintiffs allegations and demonstrated a thorough knowledge of the factual and legal issues in the case. Because nothing in the record indicates that a hearing was needed to assist the court in determining whether sanctions were warranted, we hold that the district court did not abuse its discretion in not conducting an evidentiary hearing.
B.
We next consider the Appellants’ claim that the district court improperly awarded attorney fees against Wilson-Simmons pursuant to 42 U.S.C. § 1988 because her claims were not frivolous, unreasonable, or without foundation.
We review a district court’s award of attorneys fees under 42 U.S.C. § 1988 based on an abuse of discretion standard. Reed v. Rhodes, 179 F.3d 453, 469 n. 2 (6th Cir.1999). “In light of a district court’s superior understanding of the litigation and the desirability of avoiding frequent appellate review of what essentially are factual matters, an award of attorneys’ fees under § 1988 is entitled to substantial deference.” Id. (quoting Hensley v. Eckerhart, 461 U.S. 424, 437, 103 S.Ct. 1933, 1941, 76 L.Ed.2d 40 (1983)) (internal quotation marks omitted).
Under 42 U.S.C. § 1988, a district court may in its discretion award attorney fees to a prevailing defendant upon a finding that “the plaintiffs action was frivolous, unreasonable, or without foundation, even though not brought in subjective bad faith.”
Wayne v. Village of Sebring, 36 F.3d 517, 530 (6th Cir.1994) (quoting
Christiansburg Garment Co. v. EEOC, 434 U.S. 412, 421, 98 S.Ct. 694, 700, 54 L.Ed.2d 648 (1978)) (internal quotation marks omitted),
cert. denied, 514 U.S. 1127, 115 S.Ct. 2000, 131 L.Ed.2d 1001 (1995). “[A] district court must resist the urge to engage in post hoc reasoning and the hindsight logic of concluding a suit is without foundation because the plaintiff ultimately does not prevail.”
Smith v. Smythe-Cramer Co., 754 F.2d 180, 183 (6th Cir.) (quoting
Christiansburg Garment Co., 434 U.S. at 421-22, 98 S.Ct. at 700),
cert. denied, 473 U.S. 906, 105 S.Ct. 3530, 87 L.Ed.2d 654 (1985). A “plaintiff should not be assessed his opponent’s attorney fees unless the court finds the claim was groundless at the outset or ‘that the plaintiff continued to litigate after it clearly became so.’ ”
Smythe-Cramer Co., 754 F.2d at 183. This “requires inquiry into the plaintiffs basis for filing suit. Awards to prevailing defendants will depend on the factual circumstances of each case.”
Id.The district court properly applied this standard. As support for her race discrimination claim, Wilson-Simmons offered as evidence the fact that she would have to pay for the costs associated with reconstructing the e-mail files. This argument is a red herring. She presented no evidence that she should have been charged the fee for a public record of $3.00 rather than the $2,500 cost of reconstructing the files. Neither did she present any evidence that the cost was in any way racially based. Furthermore, the district court found that there was no evidence to indicate that any of the five co-workers she had identified were involved or that the alleged e-mail even existed. Wilson-Simmons proffered no evidence regarding when the e-mail had been sent, who had sent it, who it was sent to, or whether her name was even mentioned.
With respect to Wilson-Simmons’ claim that the Defendants failed to investí-
