OPINION

KING, Circuit Judge:

By Notice to Show Cause issued on January 5, 2011 (the "Notice"), this Court's Standing Panel on Attorney Discipline initiated disciplinary proceedings against respondent Thomas Liotti, a member of the New York bar and the bar of this Court, arising from his conduct during the appeal in United States v. Giannone, No. 07-4844(L).1 The Notice levied five separate charges against Liotti for violations of the applicable rules of professional conduct, primarily for factual misrepresentations. Liotti responded to the Notice, acknowledging various misrepresentations but maintaining that they were neither intentional nor worthy of disciplinary action. We disagree and conclude that Liotti's conduct did, in fact, contravene the applicable rules of professional conduct. As a result, as further explained below, we impose a public admonishment.2

I.

A.

The five charges contained in the Notice are summarized and explained as follows.

1.

According to the First Charge, Mr. Liotti improperly joined separate and unrelated quotations in the Giannone reply brief, causing them to appear as a single exchange on the same topic. By combining these separate passages—located two pages apart in the trial transcript—as a single series of questions and answers, Liotti created the erroneous impression that the passages were actually sequential, rather than separate, the effect of which tended to support his contention that the government had failed to prove an offense.

2.

The Second Charge alleges that Mr. Liotti, in the Giannone opening brief, falsely accused the trial judge of suppressing evidence. Namely, Liotti asserted on appeal that the judge improperly withheld a letter written to her by an informant, revealing that the informant had used illegal drugs while working with government agents in Giannone's case. The informant's letter—dated March 1, 2007, four days prior to the March 5 commencement of Giannone's trial—was both postmarked and received by the district court after the trial concluded on March 8.3 In denying Giannone's request for a new trial, the judge found that the court had received the letter on March 13, 2007. Also, according to the judge, the letter appeared to be postmarked March 12, 2007. The envelope containing the letter reflects that the U.S. Marshal x-rayed it on March 13, 2007. Notwithstanding the court's explicit finding to the contrary, Liotti asserted in the Giannone opening brief that the judge "received the letter on March 1, 2007," and the brief insisted that she "sat on this letter during the course of the trial." Br. of Appellant 80.

3.

The Third Charge alleges that, in the Giannone opening brief, Mr. Liotti misrepresented facts pertinent to an unsuccessful change of venue motion. In support of his appellate contention that venue should have been transferred to New York, Liotti accused the government of intentionally overestimating the expected length of Giannone's trial—i.e., that it would last approximately two weeks—and maintained that the government had padded its estimate in order to keep the case in South Carolina and defeat the venue motion. In reality, it was Liotti who estimated the trial would last two weeks; the government actually disagreed, surmising that the trial would last "3-4 days." See United States v. Giannone, No. 3:06-cr-01011 (D.S.C. Mar. 2, 2007). In its response brief, the government exposed Liotti's misstatement and Liotti replied in an inappropriately discourteous manner.

4.

As to the Fourth Charge, the Notice alleges that Mr. Liotti made misrepresentations in a sworn Declaration filed in the district court and invoked on appeal. Liotti's Declaration asserted, inter alia, that Giannone had conducted an internet chat on a computer in Liotti's office prior to trial, and that the chat established Giannone's innocence. By filing the Declaration, Liotti could have become a witness in his client's case. On appeal, Liotti relied on the Declaration to argue his client's innocence, even though Giannone had made post-trial admissions to a government agent that he had faked the internet chat. Liotti did not, however, reveal his client's post-trial admissions to this Court.

5.

Finally, the Fifth Charge alleges that, in the Giannone reply brief, Mr. Liotti asserted without any record support that two of the Secret Service agents involved in Giannone's investigation had been fired for misconduct. At oral argument, Liotti sought to downplay the unsupported revelation, offhandedly maintaining that the government was in a better position to provide evidence concerning disciplinary actions against the officers.4

B.

The Notice directed Mr. Liotti to demonstrate why appropriate disciplinary measures, authorized by the Local Rules of Appellate Procedure of this Court (the "Local Rules"), should not be imposed. The Local Rules provide, in the pertinent part of Rule 46(g), that

Local R.App. P. 46(g)(1)(c).

The Notice referenced relevant portions of the New York Rules of Professional Conduct (the "New York Rules"), which apply in these proceedings because Mr. Liotti's office is located in the State of New York. The New York Rules provide, inter alia, that a lawyer shall not "engage in conduct involving dishonesty, fraud, deceit or misrepresentation[.]" N.Y. Rules Prof'l Conduct R. 8.4(c) (emphasis added). The New York Rules further specify that a lawyer shall not knowingly "make a false statement of fact or law to a tribunal or fail to correct a false statement of material fact or law previously made to the tribunal by the lawyer." N.Y. Rules Prof'l Conduct R. 3.3(a)(1), 3.3(f)(2). These Rules also bar a lawyer from knowingly "offer[ing] or us[ing] evidence that the lawyer knows to be false" and "engag[ing] in undignified or discourteous conduct." N.Y. Rules Prof'l Conduct R. 3.3(a)(3). A lawyer is precluded from acting as an advocate in a matter in which he is likely to be a witness, and he is barred from making false statements concerning the integrity of a judge. See N.Y. Rules Prof'l Conduct R. 3.7, 8.2(a).

II.

A.

In response to the Notice, Mr. Liotti filed his affidavit addressing the five charges (the "Affidavit"), as well as several supporting letters and a response brief.

1.

As explained in more detail below, the admissions contained within Mr. Liotti's Affidavit by themselves support the imposition of discipline. We thus set forth the Affidavit in haec verba:

J.A. 269-71.5

2.

In further response to the Notice, Mr. Liotti submitted several supporting letters from his bar colleagues attesting to his good character. The authors of these letters vouch for Liotti's legal ability and professional competence, but, for the most part, do not discuss the details of these disciplinary proceedings.6 The letters from Liotti's colleagues also describe him as a passionate and zealous advocate for his clients. Included are letters from two district judges who declined to provide character evidence in the absence of a subpoena or court order. A third district judge advised that Liotti had appeared before him in a number of matters and had always conducted himself appropriately and professionally.

3.

In Mr. Liotti's response brief in this proceeding, he emphasizes that he is an experienced and respected member of the New York bar, having practiced law for more than thirty-three years and attaining an "AV rating" (the "highest possible rating") from Martindale-Hubbell. Br. of Resp't 47. His brief, like his Affidavit, addresses each of the charges, essentially admitting their substance, primarily attributing his actions to mistakes and poor judgment, and denying any intentional misconduct. Liotti expresses regret for his actions and contends that the charges, considered either separately or collectively, fail to justify any disciplinary measures.

As to the First Charge, the response brief explains that, in combining two portions of the trial transcript in the Giannone reply brief, Mr. Liotti was actually seeking to make two distinct arguments, but now recognizes that he should not have combined the excerpts without proper qualification or explanation. With respect to the Second Charge, Liotti's response brief maintains that he was reasonably permitted to call into question the district judge's finding that the informant's letter was not received until after Giannone's trial. Concerning the Third Charge, the brief urges that Liotti was under the incorrect impression that it was the prosecutor, rather than he, who estimated the trial would last two weeks.

Addressing the Fourth Charge, the response brief asserts that Mr. Liotti's Declaration was merely a proffer of what the evidence would show, and that the Declaration was implicitly (i.e., without objection from the government or the district court) sanctioned by the court. Regarding his failure to correct the inaccuracies of the Declaration, Liotti suggests that Giannone's post-trial admissions were unclear and later recanted, and that such corrections would have been immaterial in any event. With respect to the Fifth Charge, the response brief argues that Liotti believed that the government agents had been fired for misconduct. This contention was apparently based on Giannone's and an informant's allegations, coupled with evidence that the agents were no longer employed with the Secret Service. Liotti admits that the Giannone record does not confirm his personal belief, but contends that there is no direct evidence that he was wrong.

B.

On October 27, 2011, Mr. Liotti, his lawyer, and the prosecuting counsel appeared in this Court for hearing and argument.7 Liotti's lawyer attributed each charge to mistake, poor judgment, or Liotti getting "carried away" in his arguments, steadfastly maintaining that none of the charges warrants formal discipline. His lawyer proposed that the informal discipline that Liotti has already endured—for example, responding to the Notice and making pleas to colleagues and judges for supporting letters—constitutes sufficient punishment for any perceived transgressions. Emphasizing that Liotti's misconduct falls short of justifying discipline, counsel entreated us to either dismiss the proceedings or impose a private discipline.

Mr. Liotti's lawyer argued that attorneys frequently make mistakes or misrepresentations during the appellate process, for which they are rarely required to answer. For that reason, counsel suggested, Liotti may have lacked proper notice that his conduct could lead to disciplinary proceedings. Finally, counsel proposed that we consider issuing Liotti a "caution letter," a confidential type of discipline used in New York when a lawyer's behavior warrants comment by a court but does not rise to the level of publicly sanctionable misconduct.8

The prosecuting counsel responded that the cumulative effect of the five charges against Mr. Liotti brings this case well within the disciplinary compass. Refuting Liotti's assertion that his experience and competence make him less culpable, the prosecuting counsel maintained that those factors render his misconduct less forgivable. According to the prosecuting counsel, experienced attorneys have a greater obligation than their younger and greener colleagues to know and adhere to the rules of professional conduct. Although counsel acknowledged the presence of mitigating factors that we must assess, he asserted that the admissions made in Liotti's Affidavit are alone sufficient to justify the imposition of discipline. And, counsel argued, because an important purpose of attorney discipline is the deterrence of other members of the bar from engaging in similar conduct, any such discipline should be publicly disclosed.

III.

We agree with the American Bar Association Standards for Imposing Lawyer Sanctions (the "ABA Standards") that the proper standard of proof for violations of the relevant rules of professional conduct is "clear and convincing evidence." See ABA Standards § 1.3. The panoply of available sanctions for attorney misconduct includes disbarment, suspension, fine, public reprimand, and private reprimand. Id. §§ 2.2-2.10. When such misconduct has been proven by clear and convincing evidence, we are obliged in formulating the appropriate discipline to consider both aggravating and mitigating factors, as well as the "potential or actual injury" resulting from the misconduct. Id. § 3.0.

A.

1.

Turning to the merits of the charges against Mr. Liotti, we examine them in ascending order of seriousness. First, we assess Liotti's erroneous quoting of the trial transcript in the Giannone reply brief (First Charge) and his incorrect claim on appeal that the government had estimated Giannone's trial would last two weeks (Third Charge). On the First Charge, combining two separate parts of the trial transcript—thereby creating the look of a fluid conversation—was clearly inappropriate. Liotti now states that he is "not sure how this oversight occurred but [takes] responsibility for it and regrets that it occurred." Aff. ¶ 5. Nevertheless, Liotti accurately cited the transcript pages for the quotations, revealing—if the record were consulted—that the questions and answers recited in the Giannone reply brief were actually obtained from different parts of the transcript. Thus, Liotti's conduct underlying the First Charge is arguably mitigated because a careful reader could access the accurate origins of the misquoted evidence.

With respect to the Third Charge, Liotti's statement in the Giannone appeal concerning the government's position on the potential duration of Giannone's trial was patently wrong, and no one was in a better position to know that than Liotti. When the government corrected Liotti on this point in its response brief, Liotti became antagonistic, asserting in reply:

J.A. 240. Put simply, Liotti's initial statement of the parties' positions, set forth in the Giannone opening brief, was a misrepresentation of the record. Liotti's concession in the reply brief, though inartfully made, may have partially corrected the misrepresentation. In his Affidavit, however, Liotti frankly admits that he "was mistaken about who made an estimate for a two-week trial." Aff. ¶ 7. In sum, Liotti's actions in connection with the First and Third Charges constitute misrepresentations to the Court.

2.

As to the Fifth Charge, Mr. Liotti's statement in the Giannone reply brief that two of the investigating agents had been fired for misconduct was apparently based on information from an informant and Liotti's own client, coupled with the undisputed fact that the agents were no longer employed by the Secret Service. Confirmation of that fact came from a post-trial declaration of the Service's Deputy Director, which was obtained by Giannone through an FOIA request in another case. The declaration does not, however, discuss or reveal anything about discipline against the agents. In his Affidavit, Liotti admits that, in making the contention that the agents had been fired for misconduct, he "should have couched [his] argument more in terms of which the evidence in the record established." Aff. ¶ 9. The absence of evidence disproving Liotti's allegation that the agents were fired for misconduct, however, does little to ameliorate the impropriety of his unsupported statements. In the circumstances, Liotti should have known that the record did not support his assertion that the Secret Service agents had been fired for misconduct.

3.

On the Fourth Charge, relating to the Declaration of Mr. Liotti concerning the internet chat between Giannone and another individual, Liotti maintains that he has not contravened Rule 3.7 of the New York Rules, which provides that "a lawyer shall not act as advocate before a tribunal in a matter in which the lawyer is likely to be a witness on a significant issue of fact unless... the testimony is authorized by the tribunal." New York courts have interpreted Rule 3.7 to require the disqualification of counsel upon the movant's showing that the attorney's testimony is necessary and that there is a substantial likelihood of prejudice if the attorney continues to act as an advocate. See Capponi v. Murphy, 772 F.Supp.2d 457, 471-72 (S.D.N.Y.2009).

Mr. Liotti's Declaration states that it was his associate, lawyer Drummond Smith—not Liotti himself—who witnessed the internet chat involving Giannone and another person. Because Smith was the witness to the chat, Liotti probably would not have been permitted to testify to what Smith saw. Moreover, evidence regarding the internet chat was otherwise available to the parties at trial, and the government never sought to call Liotti as a witness or urge his disqualification as counsel. As a result, this aspect of the Declaration does not give rise to a violation of Rule 3.7.

Nevertheless, in using the Declaration and the internet chat to support his appellate contentions, Mr. Liotti neglected to inform this Court that Giannone had already admitted to the government in a post-trial interview that he had faked the internet chat. Liotti apparently made the Declaration on the basis of an internet dialogue that took place in his office but outside his presence, and his Affidavit and brief admit that he is not proficient with computers. See Br. of Resp't 37 ("Liotti is not knowledgeable in the way of computers"); Aff. ¶ 8. Liotti's failure to reveal in the Giannone appeal that his client had already admitted to the government that the internet chat was a fake constituted a failure to correct a prior misrepresentation of material fact. Liotti maintains, however, that he did not know that the internet chat was a fake—even though Giannone had admitted that fact to the government—because Giannone later denied making the admission.9 Giannone's recantation carries little weight, however, inasmuch as Smith had witnessed Giannone's post-trial admission to the government. Consequently, Liotti should have known that the statements in his Declaration with respect to the internet chat were unfounded. And he should have clarified those facts to the Court. See N.Y. Rules Prof'l Conduct R. 3.3(a)(1).

4.

The most serious of the charges lodged against Mr. Liotti is the Second Charge—Liotti's false accusation that the district judge suppressed the informant's letter. Those assertions constitute an unwarranted misrepresentation of the record and an unsupported impugnment of the judge's character. Nevertheless, it appears from his present contentions that Liotti was seeking to argue in the Giannone appeal that, because the informant's letter was dated March 1, 2007, the judge's finding of fact concerning her receipt of the letter on March 13, 2007, was clearly erroneous.10 In any event, Liotti now argues that the judge's finding with respect to the date she received the letter was not conclusive. That is not, however, how he posited the proposition in Giannone's appeal.

In his Affidavit, Liotti recognizes "that [his] arguments on this point should have been handled differently so as to avoid the appearance that [he] was attacking the court's credibility or integrity[.]" Aff. ¶ 6. Regardless of whether Liotti thought he was entitled to present a good faith challenge to the court's findings of fact, his assertions about the trial judge in the Giannone appeal, together with the manner in which he presented them, constituted unfounded accusations against the judge and contravened the applicable rules.

B.

Consistent with the foregoing, we are satisfied that the factual allegations in the Notice regarding misrepresentations to the Court are supported by clear and convincing evidence. More specifically, Mr. Liotti made misrepresentations to the Court, in contravention of Rule 8.4 of the New York Rules, which provides, in pertinent part, that a lawyer shall not "engage in conduct involving ... misrepresentation[s]." Liotti's misrepresentations in the Giannone appeal encompass the following:

Because Mr. Liotti's conduct during the Giannone appeal violated the New York Rules, it also contravened the Local Rules. See Local Rules App. P. 46(g)(1)(c).

IV.

As we have heretofore recognized, "our adversary system depends on a most jealous safeguarding of truth and candor." United States v. Shaffer Equip. Co., 11 F.3d 450, 463 (4th Cir.1993). One of the most important aspects of the work of an appellate lawyer is the obligation to provide the court with a fair and accurate presentation of the relevant facts. Indeed, many of our colleagues on the bench would characterize that obligation as paramount, and there is no valid reason for any lawyer to do otherwise. As John Adams explained in his successful defense of the British soldiers charged in the Boston Massacre, "facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passion, they cannot alter the state of facts and evidence." David McCullough, John Adams 52 (Simon & Schuster 2001). Our good colleague Judge Niemeyer, writing for the Court in Shaffer Equipment, emphasized the importance of an accurate presentation of the pertinent facts, aptly relating:

11 F.3d at 457. Misrepresentations of fact by an officer of the court will, if ignored, cast a menacing shadow on a judicial system that is designed to illuminate truth and promote fairness.

As Mr. Liotti's response brief acknowledges, a lawyer is charged with the challenging role of advocating zealously for his client and at the same time observing the applicable rules of professional conduct. Sustaining a lawyer's "dual obligations to clients and to the system of justice" is a far from trifling responsibility. In re Snyder, 472 U.S. 634, 644, 105 S.Ct. 2874, 86 L.Ed.2d 504 (1985). As a result, the privilege of bar membership must be jealously guarded, and loose footing on the high standards of professional conduct must find its purchase in balanced discipline.

Although Mr. Liotti's conduct reflects, at best, a troublesome pattern of carelessness, his misrepresentations appear to have been largely discovered by the Court, through its own diligence and the opposing counsel's efforts, prior to the Giannone appeal being resolved. As a result, there was no resulting prejudice to either party. We agree with the prosecuting counsel that Liotti's extensive experience and competence as a lawyer constitutes an aggravating factor—rather than a mitigating one—in our evaluation of the discipline issues. In mitigation, however, the record fails to show a history of misconduct on the part of Liotti, and his client was not harmed by his transgressions here. There also does not appear to have been any selfish motive underlying Liotti's actions.

To his credit, Mr. Liotti handled Giannone's appeal on a court-appointed basis and achieved success for his client on the sentencing issues. Furthermore, we readily accept the proposition that Liotti is a capable attorney and that, as a trial lawyer, he possesses a fine reputation for being a zealous advocate for his clients.12 Thus, Liotti's misconduct in the underlying appeal appears as an isolated event, and it is inconsistent with his otherwise fine career. And it is commendable that Liotti has now largely recognized and apologized for his misrepresentations, acknowledging that several of his actions resulted from mistakes and poor judgment.

Notwithstanding the foregoing considerations in mitigation, we are constrained to conclude that Mr. Liotti's cumulative conduct warrants some measure of discipline. Our assessment of the pertinent legal principles and authorities reveals that potential disciplines such as disbarment, suspension, or fine generally apply to more serious misconduct than that found here.13 Nevertheless, Liotti's violations of the applicable rules should not be ignored. According to the ABA Standards, another type of discipline, known as an admonition, may appropriately be utilized

ABA Standards § 6.14.

The ABA Standards advise that the purpose of lawyer discipline is to "protect the public and the administration of justice from lawyers who have not discharged ... their professional duties to clients, the public, the legal system, and the legal profession." ABA Standards § 1.1. The unsettling repetition of Mr. Liotti's misrepresentations and the need to deter others from engaging in similar conduct militate in favor of public discipline. In light of the various mitigating factors, however, the purposes of discipline will be sufficiently served in this proceeding if we temper our disposition with a strong measure of leniency. As a result, the appropriate disposition is the imposition of one of the less severe disciplines available—a public admonition.14

Pursuant to the foregoing, Mr. Liotti is hereby

PUBLICLY ADMONISHED.
