I.
The defendant, Patrice Hurn, was an employee of the United States Postal Ser *1361 vice who painted as a hobby. She had a website advertising her painting services. On December 4, 2000, she submitted a claim for disability due to carpal tunnel syndrome that she alleged was caused by her job. Although her claim was initially accepted, in May, 2001, postal inspectors opened an investigation to examine the possibility that she had committed workers’ compensation fraud. In August, the Postal Service offered her a new job to accommodate her disability, but she sent them a letter stating that she did not have the physical capacity to perform the duties of that job, and that it was too far away for her to drive to.
As part of the ongoing investigation of Hurn, two undercover postal inspectors separately hired her at different times to paint pictures of their pets. They paid her a total of approximately $500; she gave one of the agents a professionally printed receipt. Shortly after each transaction, the postal service sent her a “1032 Form” in connection with her workers’ compensation benefits, which required her to report any outside income she had received. Both times, she failed to report her income from her paintings on the forms.
On September 18, 2002, a federal grand jury indicted Hurn for three counts of violating 18 U.S.C. § 1920, which prohibits making false statements in connection with federal worker’s compensation programs. Count I was based on her letter to the postal service claiming she was unable to perform the duties of the new job which she had been offered. Counts II and III were for the two 1032 Forms on which she neglected to report her income from painting. Hurn pled not guilty. She was tried before a jury, convicted on all counts, and sentenced to five months’ imprisonment.
Part II of this opinion considers Hum’s challenge to the adequacy of the district court’s jury instructions. Part III turns to her claim that the district court violated her right to a fair trial by excluding a critical defense witness. Finally, Part IV considers the sufficiency of the evidence to support her convictions under Counts II and III.
II.
Hurn first contends that the district court erred in failing to instruct the jury to determine whether her false statements actually led to her receiving over $1,000 in workers’ compensation benefits. 18 U.S.C. § 1920 provides, “Whoever knowingly and willfully ... makes a false, fictitious, or fraudulent statement or representation ... in connection with the application for or receipt of compensation or other benefit or payment [under a federal program] shall be guilty of perjury.” The statute goes on to state,
[0]n conviction thereof [the defendant] shall be punished by a fine under this title, or by imprisonment for not more than 5 years, or both; but if the amount of the benefits falsely obtained does not exceed $1,000, such person shall be punished by a fine under this title, or by imprisonment for not more than 1 year, or both.
Id.
The maximum sentence to which a § 1920 defendant is subject depends on the amount of benefits she “falsely obtained.” In
Apprendi v. Neiv Jersey,
Hurn maintains that this instruction was insufficient, however, because it did not require the jury to find that a causal link existed between her false statement and her receipt of more than $1,000 in workers’ compensation benefits. She argues that the district court should have asked the jury whether, “because of the false statement or report, [Hurn] obtained more than $1,000 in federal worker’s compensation funds.” We agree with Hurn that the plain meaning of the statute requires that the jury find such a causal link for a defendant to be subject to the statute’s enhanced penalty regime. We believe that the instructions given, however, satisfy this requirement. The court asked the jury whether the amount of benefits “falsely obtained” exceeded $1,000. A reasonable juror would be likely to conclude that a benefit is obtained “falsely” if it is obtained as a result of a fraudulent or misleading statement or omission. Therefore, the instruction as given fairly includes the causation requirement to which the defendant points. Moreover, because the instruction was essentially lifted from the text of the statute, it would be almost impossible for us to conclude that it did not convey the statute’s requirements. Consequently, we reject Hum’s challenge to the jury instructions.
III.
Hum’s next claim is that the district court’s exclusion of Attorney Paul Felser as a defense witness violated her constitutional right to a fair trial. Hurn sought to have Felser testify that, under the “concurrent dissimilar employment” doctrine, her benefits would not have been reduced if she had truthfully reported her income from painting on the 1032 Forms. Hurn claims that, because her benefits would have remained the same whether she lied or told the truth about her painting income, she had no reason to deliberately or willfully defraud the government. Had the jury heard this doctrine, it would likely have concluded that the omission of this information from the form was the result of either an oversight or misunderstanding of the forms.
The Sixth Amendment to the United States Constitution guarantees defendants the right to have “compulsory process for obtaining witnesses in his favor.”
U.S. Const,
amend. VI. Implicit in this right— as well as in the basic notion of “due process of law” in general,
see U.S. Const.
amend V — is the idea that criminal defendants must be afforded the opportunity to present evidence in their favor.
See Specht v. Patterson,
In assessing a defendant’s claims under the Fifth and Sixth Amendments to call witnesses in her defense, we engage in a two-step analysis. We first examine whether this right was actually violated, then turn to whether this error was
*1363
“harmless beyond a reasonable doubt” under
Chapman v. California,
A district court’s exclusion of a defendant’s evidence violates these Compulsory Process and Due Process guarantees in four circumstances. 1 First, a defendant must generally be permitted to introduce evidence directly pertaining to any of the actual elements of the charged offense or an affirmative defense. 2 Second, a defendant must generally be permitted to introduce evidence pertaining to collateral matters that, through a reasonable chain of inferences, could make the existence of one or more of the elements of the charged offense or an affirmative defense more or less certain. Third, a defendant generally has the right to introduce evidence that is not itself tied to any of the elements of a crime or affirmative defense, but that could have a substantial impact on the credibility of an important government witness. Finally, a defendant must generally be permitted to introduce evidence that, while not directly or indirectly relevant to any of the elements of the charged events, nevertheless tends to place the story presented by the prosecution in a significantly different light, such that a reasonable jury might receive it differently. We review each of these standards in turn. 3
A.
The most obvious component of a defendant’s Fifth and Sixth Amendment right to present evidence in his favor is to present evidence that has a direct bearing on a formal element of the charged offense. “A defendant’s right to a fair trial is violated when the evidence excluded is material in the sense of a crucial, critical, highly significant factor.”
United States v. Ramos,
Hurn is unable to articulate a constitutional violation under this theory. She contends that Felser was going to testify about her continued eligibility for benefits under the “concurrent dissimilar employment” doctrine. None of the elements of 18 U.S.C. § 1920 directly address a defendant’s continued eligibility for benefits. Moreover, Hurn did not offer an affirmative defense to which this testimony would be directly material. Consequently, Hurn must advance a different theory under which the court wrongfully excluded this testimony.
B.
A defendant also has the right to introduce evidence that is not directly relevant to an element of the offense, but that makes the existence or non-existence of some collateral matter somewhat more or less likely, where that collateral matter bears a sufficiently close relationship to an element of the offense. In
United States v. Sheffield,
Evidence proving that such a custom existed was not directly relevant to any of the elements of embezzlement. Nevertheless, the existence of the custom was a collateral matter that was itself relevant to the mens rea element of the offense. That is, if the defendant was acting pursuant to an established, authorized custom, then he was not intentionally doing anything wrong. Id. at 1170 (“Evidence of the gift-making custom was relevant to [the defendant’s] state of mind when he ordered the production of fishing lure molds.”). Consequently, exclusion of the evidence violated the defendant’s rights. Id.
*1365
Similarly, in
United States v. Lankford,
A defendant also has the constitutional right under this theory to introduce evidence concerning a collateral matter where the government attempts to use that collateral matter as the basis for securing a conviction. In
United States v. Word,
During trial, the government was able to argue inferences favorable to the prosecution based upon the romantic relationship between the two co-defendants while the defendant ... was prohibited from introducing evidence that told a different story about the relationship and that might have contradicted or undercut those inferences.
Id. at 1213. Consequently, we vacated the conviction and ordered a new trial based on the exclusion of evidence concerning this collateral matter.
Conversely, where the proffered evidence does not bear a logical relationship to an element of the offense or an affirmative defense, whether direct or indirect, a defendant has no right to introduce that evidence and a district court may properly exclude it.
See Ramos,
Hurn is unable to prevail under this theory because there is a crucial break in her proposed chain of reasoning. The existence of the “concurrent dissimilar employment” doctrine (a collateral matter) could only have reduced her motive to lie when filling out the documents (a factor which goes to the mens rea element of the offense) if she knew about it. Hurn does not argue on appeal that she had consulted with Felser prior to filling out the forms, and did not offer any other evidence to suggest that she was aware of the doctrine. Indeed, if it would take an expert’s testimony to make a jury aware of the “concurrent dissimilar employment” doctrine, it is highly unlikely that she knew of it at the time she filled out the forms. Consequently, she failed to offer the vital link in the chain that would have made that collateral matter relevant to an element of the charged defense.
C.
A third facet of the defendant’s right to present evidence is to introduce evidence that, while not directly or indirectly relevant to an element of an offense or affirmative defense, attacks the credibility of important government witnesses. In United States v. Davis, for example, we reversed a conviction because the trial court had excluded evidence, where
[t]he purpose of the proffered evidence was to discredit the key government witness ... without whom the government would have had no case against [the defendant].... No other impeachment evidence, except for [the key government witness’] admission of prior felony convictions and the circumstances surrounding his cooperation with the prosecution, was admitted.... The excluded evidence here would have gone further than character evidence. The two witnesses would have testified to [the witness’] reputation for lacking truth and veracity and that they would not believe him under oath.
D.
In some cases, the government’s selective presentation of entirely truthful evi *1367 dence can cast a defendant in an inaccurate, unfavorable light, or make entirely legitimate, normal, or accepted acts appear unusual or suspicious. In these situations, the defendant has the right to introduce additional evidence to dispel this unjustified taint, even if that evidence does not directly or indirectly bear on a particular element of an offense.
For example, in
United States v. Todd,
The right to place the government’s evidence in context is not unlimited, however. In
United States v. Funches,
we affirmed a conviction despite the fact that some contextual evidence was excluded because “[h]ad the jury heard [the excluded evidence], the jury nonetheless would have lacked a reason in law not to convict.”
In this case, Felser’s testimony was not necessary to correct any misleading impressions that may have been created by the government’s evidence. As discussed earlier, because neither Felser nor anyone else can testify that Hurn was aware of this doctrine, his testimony cannot be woven into a larger defense narrative. Moreover, none of the government’s evidence focused on whether or not Hum’s benefits would actually have been reduced had she truthfully reported her income from painting. Consequently, she cannot argue that the government was unfairly attempting to use this collateral matter to her disadvantage.
In short, there is no theory under which Hum’s constitutional rights were violated by the exclusion of this evidence. Further undermining Hum’s argument on this point is the fact that the district court offered to instruct the jury on the “concurrent dissimilar employment” doctrine as a
*1368
matter of law, but Hurn declined. Since this theory was the only matter to which Felser was going to testify, the district court’s offer precluded any need for him to be called as a witness. By making this offer, the district court rendered any error in excluding Felser irrelevant.
See United States v. Buckley,
TV.
The defendant’s final claim is that the evidence was not sufficient to prove Counts II and III of the indictment. These counts claimed that Hurn had perjured herself by failing to report income from a “business enterprise” on the 1032 Forms. Hurn argues on appeal that painting was a hobby; the fact that she occasionally sold a few paintings informally for a few hundred dollars did not make her art an enterprise. We are quite sympathetic to this argument, and might be inclined to reverse her convictions on these counts had this argument been raised at trial. As the government points out in its brief, however, Hurn failed to move at trial for a directed verdict of acquittal on this basis. Consequently, we review this conviction only for plain error.
See United States v. Hunerlach,
To obtain a reversal under the plain error standard, a defendant must demonstrate, among other things, not only that the error violated her substantial rights (which this error arguably did), but that it “seriously affect[s] the fairness, integrity or public reputation of judicial proceedings.”
United States v. Olano,
A reasonable jury would have been fully justified in concluding that Hurn affirmatively lied on her forms, thus violating § 1920, even though her conduct did not actually fall within the narrow confines of the indictment. The forms asked whether she was “self-employed or involved in any business enterprise in the past 15 months.” Moreover, they expressly directed her to “[rjeport ALL self-employment or involvement in business enterprises.” The forms further specified that the employment to which they were referring “include[d] but [was] not limited to ... providing services in exchange for money, goods, or other services. The kinds of services which you must report include ... painting, contracting, child care, odd jobs, etc.” Finally, the forms specifically stated, “Even if your activities *1369 were part-time or intermittent, you must report them.” Upholding Hurn’s conviction for lying on this form is hardly unfair; to the contrary, allowing her to escape punishment on a minor technicality in the indictment would be unjust.
The defendant’s convictions are
AFFIRMED.
Notes
. We do not address the closely related question of when a district court's restrictions on a defendant's cross-examination of a prosecution witness violates the Sixth Amendment Confrontation Clause. See U.S. Const, amend VI ("In all criminal prosecutions, the accused shall enjoy the right ... to be confronted with the witnesses against him....").
. The modifier "generally” is used because otherwise relevant evidence may sometimes validly be excluded under the Rules of Evidence. Nevertheless, the fact that a particular rule of evidence requires the exclusion of certain evidence is not dispositive, as particular applications of a generally valid rule may unconstitutionally deny a defendant his rights under the Compulsory Process or Due Process Clauses.
See Knight v. Dugger,
.It is easier for a defendant to obtain a reversal on direct appeal on the basis of improperly excluded evidence than it is for a defendant to obtain a writ of habeas corpus on the same ground. "It is fundamental that federal courts possess only limited authority to consider state evidentiary rulings in a ha-beas proceeding by a state prisoner. Our inquiry must be limited to determining whether the evidentiary ruling was so prejudicial ... as to deny fundamental fairness to the criminal trial, thus violating the due process clause.”
Phillips v. Wainwright,
. Decisions of the Fifth Circuit handed down prior to September 30, 1981, are binding in the Eleventh Circuit.
Bonner v. City of Prichard,
. Had this been a bench trial, a motion for acquittal would not have been necessary to preserve Hum's “sufficiency of the evidence” argument for appeal.
