Opinion for the Court by Circuit Judge ROGERS.
This is an appeal from the grant of summary judgment in an employment discrimination case filed pursuant to 42 U.S.C. § 1981. As a threshold matter, the *139 National Association of Letter Carriers (“the Union”) contends that the court lacks jurisdiction because the appeal is untimely. Although the notice of appeal was not timely docketed in the district court, we hold that the appeal is timely because the notice of appeal was electronically filed within the thirty-day period for appeals in a civil case. Under the federal rules of civil and appellate procedure, the district court electronic filing system’s failure to docket the notice within that period is not attributable to Royall. On the merits, we hold that the grant of summary judgment was appropriate because there was no evidence from which a reasonable jury could find that the Union’s reason for terminating Charles Royall’s employment was a pretext for unlawful discrimination.
I.
In February 2002, the Union hired Ro-yall, an African American, as an accounting manager. His responsibilities included handling payroll and the associated deductions and benefits, entering vendor bills into the accounting system, and ensuring that the Union paid its bills and taxes on time. According to Union President William Young and the Secretary-Treasurer Jane Broendel, Royall indicated during his employment interview that “he was familiar” with the J.D. Edwards accounting program that the Union used, and that “he was a quick study, and he would be right up and running with it.” Young Dep. at 28; see Broendel Dep. at 13.
From the Union’s perspective, Royall’s performance did not meet expectations. According to Young, Royall “never did grasp [the] J.D. Edwards [system],” and, as a result, failed to make entries into the system that would have allowed the W-2 forms to be generated automatically. Young Dep. at 28. He based his opinion on what Broendel and finance director Ronald Stubblefield told him and on what he personally knew. Sukja Neidlinger, the payroll clerk, reported that it took Royall two months to learn basic payroll. Other Union employees also noted inadequacies in Royall’s performance, including paying bills, taxes, and employees’ benefits late. The Union incurred penalties because of the late tax payments during Royall’s tenure. Several Union officers, including Young and Broendel, received complaints about these late payments from employees and vendors; they also received complaints about Royall’s performance from other employees. Broendel was of the view that the only satisfactory elements of Royall’s performance were that he arrived on time, did not leave early, and did not call in sick excessively.
Frank Sclafani, a temporary employee who later became the finance director, documented some of the inadequacies in Ro-yall’s performance in an undated memorandum to Broendel about the accounting department generally. While observing that there were “always two sides to every story,” Sclafani advised that Royall’s accounting abilities were “suspect” and that “unless actively supervised [Royall’s work] is often incomplete or not timely, and in too many cases, inaccurate.” Royall also did not demonstrate a willingness to take on or complete the tasks assigned to him, causing the finance director over time to rely on him less and less. In Sclafani’s opinion, Royall’s lack of ability would continue to have “a major detrimental effect on the work flow in the department.” Scla-fani also pointed out that while the J.D. Edwards system was “very versatile,” its database was neither intuitive nor were the day-to-day accounting processes easy to learn, and the system required a “highly proficient user to harness [its] power and make the database a useful accounting tool.”
*140 Disputing the evidence about his performance, Royall claimed that he had been complimented on his satisfactory performance on several occasions. He pointed out that his position had been vacant for six months and that he had caught up on the bonds, made deposits for taxes and payroll on time, eliminated insurance premium payments for people who had died, and completed Neidlinger’s payroll while she was on vacation. Stubblefield complimented him for getting current on the bonds, as had Broendel, who had never criticized him despite almost daily interaction, and Royall was unaware that Neidlinger had any “problems” with him. In fact, prior to his termination, Royall had never been disciplined for the alleged inadequacies in his performance. Further, Royall pointed out that various of the errors the Union officers had described took place several months before his termination. Additionally, he claimed that he knew nothing about the J.D. Edwards system before he started working for the Union. Critically, however, Royall did not deny that on two occasions he had paid the Union’s taxes late and paid employee benefit claims late. He also acknowledged that there were other complaints about his work but attributed some of the problems to matters that were his supervisor’s responsibility.
Upon discussing Royall’s performance with Stubblefield and Broendel, Young fired Royall six months after he was hired. According to Young, “the only reason Ro-yall’s employment was terminated is he was not able to do all of the functions of the position that he was hired to do, and we couldn’t get the finance department in order without someone who was able to do the things that he was supposed to do.” Young Dep. at 50.
Royall filed suit against the Union on the ground that he was terminated because of his race in violation of § 1981. He alleged that he had performed his duties in an acceptable manner, that claims he was not doing his job were false, and that he was replaced by a white male who was allowed to return to his former position after a few months of inadequate performance. He alleged as well that the Union terminated the employment of another African American male, Stubblefield, after Royall’s discharge because he “ostensibly ‘didn’t fit in.’” Compl. ¶12. The Union answered and then moved for summary judgment, which Royall opposed. The district court granted the Union’s motion and Royall appeals.
II.
The Federal Rules of Appellate Procedure require a notice of appeal in a civil case to be filed within thirty days of entry of the judgment or order being appealed. Fed. R.App. P. 4(a)(1). This time period is jurisdictional and mandatory.
Bowles v. Russell,
The local rules of the United States District Court for the District of Columbia require all documents to be submitted electronically. D.D.C. R. 5.4(a). The clerk of the district court, however, has *141 issued general information stating that a notice of appeal “cannot be filed by an attorney using the CM/ECF system.” 1 More recently, the clerk has issued instructions for online filing of notices of appeal. 2 The Union does not suggest that Royall’s appeal is untimely because of noncompliance with the requirement of the local rule to submit a paper copy of the notice of appeal when filing it electronically and we have no occasion to address this issue.
The relevant events are undisputed except insofar as the Union challenges Ro-yall’s claim that his appeal was successfully filed.
On September 26, 2007, Royall, by and through counsel, filed a notice of appeal using the District Court’s electronic case filing system ... and opposing counsel were served with copies by mail. As part of the ECF process a credit card number and related information [were] submitted so that the required fees could be paid. That same day Royall’s counsel received electronic confirmation from the Court that the fee had been charged to his credit card.
Sometime in October 2007 Royall’s counsel called the clerk of this Court to inquire about filing a docketing statement and when he might receive a scheduling order. The clerk informed him that the record had not yet been transmitted; and that when it was he would be notified.
On November 21, 2007, Royall’s counsel again contacted the clerk of this Court and when informed that the record had still not been transmitted, he contacted the District Court. It was during that telephone conversation that counsel was informed that the District Court had not docketed the notice of appeal which had been filed almost two months earlier. He immediately sent a letter to the clerk by facsimile transmission, attaching thereto a copy of the notice of appeal and his credit card statement showing that he had been charged $455 by “USDC DC WASHINGTON DC” on September 26, 2007. He also related that he had spoken with the ECF coordinator on that day, had been told the system was experiencing a glitch and later told the system was working properly. He suggested this might account for the lack of docket entry.
On or about that same day, the District Court clerk docketed the notice as of September 26, 2007; and the record was subsequently transmitted to this Court.
Appellant’s Br. 10 (internal citations omitted).
The filing date on the docket sheet, “09/26/2007,” supports Royall’s contention that the notice of appeal was timely filed, as does the credit card invoice indicating a September 26, 2007 charge from the district court of $455, the fee for filing a *142 notice of appeal. A September 26, 2007 filing would be timely because the thirty-day period began on August 29, 2007, when the district court granted summary judgment to the Union.
Without seriously disputing the electronic submission and receipt date, the Union maintains that the notice was not “filed” in satisfaction of Rule 4(b) because the clerk (or the clerk’s computer system) failed to register the filing on the docket sheet until November 21, 2007 — nearly two months after the deadline. This argument fails because the date of receipt controls in this case. The Supreme Court has long recognized that, with exceptions not relevant here, receipt by the clerk within the required time period satisfies the timely filing requirement for a notice of appeal in a civil case,
see Houston v. Lack,
First, because Royall tendered his notice of appeal to the clerk within the thirty-day filing period,
Bowles
does not require dismissal of the appeal. In
Bowles,
the district court reopened the time to file an appeal but told Bowles that he had seventeen days to file rather than the fourteen days provided in the Rule.
Bowles,
Second, the Union is correct that backdating a late notice does not render it timely, but that is not what happened here. The clerk simply deemed the notice filed on the date of Royall’s electronic submission. Although a litigant is not “entitled to rely on a court’s mere acceptance and processing of an untimely notice of appeal,”
Moore v. South Carolina Labor Bd.,
Third, under the district court’s local rules, electronic filing “constitutes filing for all purposes under the Federal Rules of Civil Procedure and the Local Rules of [the district court],” D.D.C. R. 5.4(c), and the electronic case filing system is thus a substitute for the clerk of the court. As the Seventh Circuit observed, noting Rule 5(e)’s requirement, now located in Rule 5(d)(4), that clerks accept documents tendered for filing, “[t]he software that operates an e-filing system acts for ‘the clerk’ as far as Rule 5 is concerned; a step forbidden by a person standing at a counter is equally forbidden to an automated
*143
agent that acts on the court’s behalf.”
Farzana K. v. Indiana Dep’t of Educ.,
[T]he fact remains that the complaint was tendered to the clerk’s office on the 30th day, and the computer’s reaction does more to show the limits of some programmer’s imagination than to render the suit untimely. Had a paper copy of the complaint been handed over the counter on July 6, a deputy clerk would have crossed out the old docket number, stamped a new one, and filed the document; there is no reason to throw this suit out of court just because the e-filing system did not know how to take an equivalent step.
Id.
Likewise, as the Second Circuit has recognized,
Contino v. United States,
Accordingly, we hold that, pursuant to the federal rules, the electronic case filing system’s failure to docket Royall’s timely submitted notice of appeal cannot be treated as a failure on his part to file timely. His situation is akin to one in which the clerk’s office misplaces a filing and then later makes the docket entry when the filing is found. Where, as here, a notice of appeal is tendered to the clerk within the filing period, “any error regarding the filing of his notice of appeal must be charged to the court, not to him.”
Baney v. Dep’t of Justice,
III.
Summary judgment is appropriate when there is no genuine issue of material fact and the “the moving party is entitled to judgment as a matter of law.”
Holcomb v. Powell,
*144
The burden-shifting framework set out in
McDonnell Douglas Corp. v. Green,
Once the employer offers this justification, the burden of production shifts back to the plaintiff, “the
McDonnell Douglas
framework falls away, and we must determine whether a reasonable jury ‘could infer discrimination’ ” based on the prima facie case, the plaintiffs challenge to the employer’s proffered justification, and any other evidence of discrimination.
Vickers v. Powell,
Here, the Union has articulated a legitimate nondiscriminatory justification for terminating Royall’s employment, namely “a steady drumbeat of complaints about Royall’s job performance.” Appel-lee’s Br. 19. Among other evidence, the testimony about Royall paying payroll taxes late, improperly entering W-2 information into the accounting software system, making the Union officers’ benefit payments late, and experiencing difficulties learning the accounting system substantiate the inadequate performance justification. The Union presented documentary evidence of the late tax payments and consequent penalties. Although the Union failed to produce documentary evidence to substantiate its other reasons for terminating Royall, explaining that some of the documents had been misplaced, the Union officers’ sworn depositions and the documentary evidence regarding the late tax payments suffice to meet the Union’s burden “to produce admissible evidence that, if believed, would establish that [its] action was motivated by a legitimate, nondiscrim
*145
inatory reason.”
Teneyck v. Omni Shoreham Hotel,
One way to discredit an employer’s justification is to show that similarly situated employees of a different race received more favorable treatment.
See Brady,
Also relevant to the discrimination
vel non
inquiry is Royall’s contention that the Union’s proffered reasons for terminating his employment are unpersuasive.
See Brady,
*146 Royall does not dispute some of the Union’s stated reasons for his termination that alone could have been sufficient nondiscriminatory grounds for terminating an at-will employee. For example, although Royall maintains that he was not responsible for all of the Union’s late tax payments and penalties, he does not challenge the Union’s documented showing that there were two late payroll tax payments during his tenure, resulting in penalties. Royall also does not deny that Young received two or three complaints that the Union had not paid officers’ benefits, but simply responds that there is no evidence of these complaints other than Young’s deposition statement and that Young’s statements are inadmissible hearsay. However, Young’s testimony about the complaints is admissible to show his reasons, not their truth. There are several other allegations that Royall does not deny, but rather criticizes for being unsupported by documentary evidence. For instance, Royall does not respond to items 35 and 36 in the Union’s statement of undisputed material facts that employees complained about payroll responsibilities that had been carried out untimely. In light of this evidence, the Union’s stated belief about Royall’s performance deficiencies was reasonable.
On appeal Royall does not contend that his deposition testimony about several incidents of racial discrimination was evidence of unlawful discrimination. Neither does he contend that the district court erred in ruling that he had conceded the issue insofar as he did not refer to this evidence in opposing the Union’s motion for summary judgment,
see
D.D.C. R. 7(b). Any arguments based on this testimony are therefore forfeited.
See Schneider v. Kissinger,
Given the consistent testimony by several Union officers that they received complaints about Royall’s work and the undisputed evidence that at least two tax payments for which he was responsible were late, a reasonable jury could not find that the Union’s officers were lying, much less that the Union’s “stated belief about the underlying facts is [unjreasonable in light of the evidence.”
