Amen E. Jumah was convicted.by a jury of knowing possession of a listed chemical, knowing, or having reasonable cause to believe, that the chemical would be used to manufacture a controlled substance in violation of 21 U.S.C. § 841(c)(2). Mr. Ju-mah’s primary defense was that he was acting under public authority when • he committed the acts giving rise to the charge. At trial, Mr. Jumah requested that the jury be instructed that the Government had the burden of disproving his public authority defense beyond a reasonable doubt. The district court agreed to instruct the jury on the elements of the public authority defense, but denied Mr. Jumah’s request to further instruct the jury that the Government had the burden of disproving the defense beyond a reasonable doubt. Following the jury’s guilty verdict, Mr. Jumah moved for a new trial on the ground that the jury had been instructed improperly with respect to the public authority defense. Acting without the benefit of the Supreme Court’s most recent guidance,

BACKGROUND
Mr. Jumah was a confidential source for the federal Drug Enforcement Administration (“DEA”). In that role, Mr. Jumah had assisted the DEA in a number of investigations into the trafficking of pseu-doephedrine, a chemical used to produce methamphetamine. He had been compensated for his services. Eventually, the DEA found that Mr. Jumah no longer was providing useful information and, in late 2002, terminated his status as a confidential source. Mr. Jumah received his last payment from the DEA in March 2003. However, after that date, he continued to approach the DEA regarding payment for past information.
In February 2004, Mr. Jumah approached Ali Qasem about a potential pseudoephedrine deal. Mr. Jumah knew Qasem had been involved in pseudoephed-rine trafficking in California. However, he apparently was unaware that, in 2002, Qas-em had pleaded guilty in a federal court in California for his participation in a conspiracy to distribute pseudoephedrine. Since his plea, Qasem had served as a confidential source for the DEA. When Mr. Jumah approached Qasem about a possible drug deal, unaware that Qasem was a confidential source, Qasem passed the information along to his handler, Agent Efren Lapuz, who, in turn, passed the information along to Agent James Jones in Chicago. Agent Jones was one of the DEA agents with whom Mr. Jumah had worked prior to his termination as a confidential source; indeed, Mr. Jumah had continued to contact him about payment for past information. Notably, Agent Jones had not asked Mr. Jumah to initiate any pseudoephedrine deals with Qasem or with anyone else during the period in question.
After confirming that the proposed deal was not' between two “friendlies,” i.e., two individuals working as informants, Agents Jones and Lapuz decided that Qasem should pursue the deal with Mr. Jumah on behalf of a fictitious methamphetamine *871 producer. In early February, Qasem and Mr. Jumah met in Chicago to arrange the deal. As Qasem was traveling to Chicago for this meeting, Mr. Jumah had contacted Agent Jones regarding payment for past information, but had not mentioned his dealings with Qasem. When Qasem arrived in Chicago, he and Mr. Jumah had several meetings, some of which were recorded by the DEA. The meetings did not culminate in a deal, but arrangements were made to complete the transaction in early March.
On March 2, 2004, Mr. Jumah and Qas-em arranged over the phone to meet that afternoon. After this call, Mr. Jumah contacted DEA Task Force Officer (“TFO”) John Kosmowski, with whom he had worked before, and informed TFO Kos-mowski that he might be meeting an individual interested in purchasing pseu-doephedrine. He did not inform TFO Kosmowski that a meeting was scheduled for that afternoon. Later that afternoon, Mr. Jumah and Qasem arranged, by telephone, a time and place for their meeting. Following this call, Mr. Jumah left a message with TFO Kosmowski that he would be meeting with Qasem. Mr. Jumah did not go into any details of the planned meeting.
When Mr. Jumah met with Qasem that afternoon, Mr. Jumah provided Qasem 1,016 pills containing pseudoephedrine as a sample for Qasem’s fictitious methamphetamine producer. Later that afternoon, Qasem contacted Mr. Jumah over the telephone to arrange a deal to purchase three hundred cases of pseudoephedrine pills. The transaction was scheduled to take place that evening at the Harrah’s casino in Joliet, Illinois. DEA agents monitored the activity by placing a recording device on Qasem and by surveilling Mr. Jumah when he left Qasem at the casino and took Qasem’s car to obtain the pseudoephed-rine. When Mr. Jumah returned to the casino, he told Qasem that the pseu-doephedrine was in the trunk of Qasem’s car, and that he would bring the car by the front of the casino to show Qasem the pseudoephedrine. Mr. Jumah then returned to Qasem’s car where he was arrested. The “pseudoephedrine” found in Qasem’s car turned out to be rock salt.
After Mr. Jumah was arrested, he claimed that he was acting on the authority of TFO Kosmowski and that he had received the sample pseudoephedrine pills that he had given Qasem from TFO Kos-mowski. Mr. Jumah later admitted that he had stolen the pills from the DEA several months earlier. Mr. Jumah was charged with violation of 21 U.S.C. § 841(c)(2) for knowing possession of a listed chemical, knowing, or having reasonable cause to believe, that the chemical will be used to manufacture a controlled substance.
At trial, Mr. Jumah’s principal defense was that he had been acting under public authority because he had been acting for the DEA in arranging the deal with Qas-em. The Government objected to the submission of any instruction on public authority to the jury, but the district court overruled the objection because it believed that adequate evidence had been introduced to put the defense in issue. The Government then proposed the Seventh Circuit pattern jury instruction for the public authority defense, along with an additional instruction reciting that the Government did not bear the burden of disproving the defense. Although Mr. Ju-mah offered no instructions of his own, he objected to the pattern jury instruction; he maintained that the jury should be instructed on the defense in the same instruction that contained the elements of the offense. He also requested that the jury be instructed that the Government had the burden to disprove the defense *872 beyond a reasonable doubt. The district court, however, rejected Mr. Jumah’s requested instructions and took the view that the Government was not required to disprove the defense beyond a reasonable doubt. R.135-6 at 444. For reasons that are not clear from the record, the Government then withdrew its requested instruction that it did not bear the burden of disproving the defense. Id. at 457.
The jury was instructed on the elements of the offense with which Mr. Jumah was charged, the Government’s burden "with respect to proof of guilt and the elements of the public authority defense. More precisely, the jury was instructed that, to find Mr. Jumah guilty, the Government was required to prove beyond a reasonable doubt that Mr. Jumah had “knowingly or intentionally possessed or distributed pseudoephedrine” and that he “possessed or distributed pseudoephedrine knowing or having reasonable cause to believe that it would be used to manufacture methamphetamine.” Id. at 520. Immediately following this elements instruction, the court instructed the jury on the public authority defense. Following the Seventh Circuit pattern jury instruction nearly verbatim, the court stated, in pertinent part, that “[a] defendant who acts in reliance on pub-lie authority does not act knowingly.” 1 Id. at 521. The jury returned a guilty verdict.
Following trial, Mr. Jumah filed a motion requesting a new trial or entry of a judgment of acquittal. He argued that the court had erred by failing to instruct the jury that the Government was required to disprove the public authority defense beyond a reasonable doubt. The court concluded that its earlier ruling was in error and that the Government was required to disprove the public authority defense beyond a reasonable doubt. The court further determined that the error was not harmless. Consequently, it granted Mr. Jumah’s motion for a new trial.
II
DISCUSSION
A.
The allocation of the burden of proof on affirmative defenses has been a vexing issue in the courts of appeals in recent times. The process has created, understandably, difficult problems for the district courts.
In
United States v. Talbott,
After the district court had ordered a new trial and had denied the Government’s motion to reconsider, the Supreme Court decided
Dixon v. United States,
— U.S. —,
B.
Our immediate task is to determine: (1) whether the public authority defense negates an element of the charged offense that the Government must prove beyond a reasonable doubt and (2) whether Congress intended to alter the common law rules governing the public authority defense in prosecutions for violations of 21 U.S.C. § 841(c)(2).
1.
We first turn to whether the public authority defense negates an element of the offense with which Mr. Jumah was charged. Commentators have identified several categories of “defenses.” These categories include failure of proof “defenses” and affirmative defenses based on justification and excuse. 2 Wayne R. La-Fave,
Substantive Criminal Law
§ 9.1(a) (2d ed.2003) [hereinafter “LaFave”]. Failure of proof “defenses” do not provide an independent basis for escaping criminal liability, but arise when a defendant introduces evidence that tends to show that the prosecution has failed to prove some element of the charged offense beyond a reasonable doubt, such as intent.
Id.
at § 9.1(a)(1). A failure of proof “defense” does not excuse conduct, but puts the prosecution to its burden of proving each ele
*874
ment of an offense beyond a reasonable doubt. Affirmative defenses of justification and excuse, on the other hand, excuse conduct otherwise punishable without controverting the evidentiary sufficiency of the Government’s proof of the elements of the underlying offense.
3
See Dixon,
The public authority defense is an affirmative defense of excuse derived from the common law.
See United States v. Pitt,
At common law, the burden of proof for all affirmative defenses of justification and excuse rests on the defendant.
Id.
at 2443 (citing
Patterson v. New York,
2.
Mr. Jumah was charged with violating 21 U.S.C. § 841(c)(2). Mr. Jumah points to nothing in the structure or history of 21 U.S.C. § 841(c)(2) that suggests that Congress intended to depart from the common law rules related to affirmative defenses. Thus, we must presume that Congress intended the federal judiciary to follow established common law rules with respect to affirmative defenses raised against a charged violation of 21 U.S.C. § 841(c)(2).
C.
Ordinarily, we review a district court’s decision regarding a motion for a new trial for an abuse of discretion.
United States v. McGee,
Our analysis in the preceding section establishes that the district court’s holding, in reliance on our decision in
Talbott,
that the Government had the burden of disproving Mr. Jumah’s public authority defense beyond a reasonable doubt was error. Given the Government’s withdrawal of its tendered instruction on the allocation of the burden of proof on the defense of public authority, we must determine, however, whether this error was
plain.
When, at the time of the district court proceedings, the prevailing circuit law was settled and that law is clearly contrary to the law at the time of appeal, “it is enough that the error be ‘plain’ at the time of appellate consideration.”
Johnson v. United States,
Turning to the third prong of our plain error analysis, an error affects a party’s substantial rights if it is prejudicial in the sense that it affects the outcome of the proceedings.
Vincent,
If an error is plain and it affects a party’s substantial rights, we shall exercise our discretion and reverse the district court’s decision if “the error ‘seriously affect[s] the fairness, integrity or public reputation of judicial proceedings.’ ”
Olano,
D.
Mr. Jumah further submits that, even if Dixon controls this ease, he was entitled to a new trial. More precisely, Mr. Jumah claims that the district court failed to instruct the jury that the defendant bears the burden of proving the affirmative defense of public authority by a preponderance of the evidence. Left without any particular guidance with respect to the standard of proof on the affirmative defense, the jury may have concluded, submits Mr. Jumah, that he had to prove that defense beyond a reasonable doubt. The jury must have interpreted the instructions in this way, he continues, because the only instructions regarding burden of proof placed the burden on the Government to prove the elements of the offense beyond a reasonable doubt.
Mr. Jumah did not request an instruction stating that the burden was on him to prove the defense by a preponderance of the evidence. We therefore must review this contention for plain error.
See United States v. Mutuc,
We shall assume,
arguendo,
that, on the basis of the foregoing discussion, the first two parts of the plain error analysis are met.
5
In short, we shall assume that fail
*877
ure to give the instruction allocating the burden of proof on the public authority instruction was error and that the error was plain. We shall focus on whether the absence of the instruction Mr. Jumah requests affected his substantial rights. Mr. Jumah must show “ ‘a reasonable probability that, but for [the error claimed], the result of the proceeding would have been different.’ ”
United States v. Dominguez Benitez,
To assist the reader, we pause to set out the instructions on the elements of the offense and the affirmative defense of public authority as given by the district court:
The defendant is charged in the indictment with knowingly and intentionally possessing and distributing a listed chemical, namely, approximately 1,016 tablets of pseudoephedrine, a List 1 chemical, knowing and having reasonable cause to believe the listed chemical would be used to manufacture a controlled substance, namely, mixtures containing a detectable amount of methamphetamine, a Schedule II narcotic drug controlled substance.
To sustain the charge of possessing or distributing pseudoephedrine, the government must prove the following propositions:
First, the defendant knowingly or intentionally possessed or distributed pseudoephedrine; second, the pseu-doephedrine is a listed chemical; and [ ] third, the defendant possessed or distributed pseudoephedrine knowing or having reasonable cause to believe that it would be used to manufacture methamphetamine.
It does not matter whether [the] defendant knew the pseudoephedrine was a listed chemical. It is sufficient [that] the defendant knew or had reasonable cause to believe that it would be used to manufacture methamphetamine or some other prohibited drug.
If you find from your consideration of all of the evidence that each of these propositions has been proven beyond a reasonable doubt, then you should find the defendant guilty.
A defendant who acts in reliance on public authority does not act knowingly and should be found not guilty.
A defendant acts under public authority if, one, the defendant is affirmatively told that his conduct would be lawful; two, the defendant is told this by an official of the government; three, the defendant actually relies on what the official tells him in taking the action; and, four, the defendant’s reliance on what he was told by the official is reasonable in light of the circumstances.
In considering whether defendant — a defendant actually relied on representa *878 tions by an official that his conduct would be lawful, you should consider all of the circumstances of their discussion, including the identity of the official, the point of law discussed, the nature of what the defendant was told, — let me say that again.
In considering whether a defendant actually relied on representations by an official that his conduct would be lawful, you should consider all of the circumstances of their discussion, including the identity of the official, the point of law discussed, the nature of what the defendant told and was told [by] the official, and whether that reliance was reasonable.
R.136-5 at 520-22.
As Mr. Jumah correctly points out, the district court did not instruct the jury about the allocation of the burden of proof for the public authority defense. He submits that the absence of such an instruction worked to his prejudice because, in its absence, the jury not only may have placed the burden of proof upon him but also may have assumed that he had to prove that defense beyond a reasonable doubt.
We cannot accept this argument. The wording and the placement of the public authority defense instruction makes it very likely that the jury assumed that the Government had the burden of disproving the public authority defense. Notably, the only instruction relating to burden of proof addressed the Government’s burden to prove each element of the offense beyond a reasonable doubt. Among the elements instructions was the admonition that the Government was required to prove that Mr. Jumah had acted knowingly. The public authority instruction followed immediately the elements instruction; it stated that Mr. Jumah could not have acted knowingly if he had acted on the reasonable belief, induced by the representation of a government official, that he was acting under public authority.
After
Dixon,
the court’s instructions would not be correct.
Dixon
makes clear that the public authority affirmative defense does not negate the knowledge element of the offense,
see Dixon,
Conclusion
For the reasons set forth in this opinion, we hold that it was plain error for the district court to grant Mr. Jumah a new trial. Further, under the circumstances presented here, it was not plain error for the district court to fail to instruct the jury that the burden rested on Mr. Jumah to *879 establish the elements of the public authority defense by a preponderance of the evidence. Accordingly, the decision of the district court is reversed and remanded with instructions to reinstate the jury’s verdict.
REVERSED and Remanded with InstruCtions
Notes
. The Seventh Circuit pattern jury instruction for the public authority defense, in whole, reads:
A defendant who acts in reliance on public authority does not act knowingly [or with the intent to (state intent requirement of statute, if any) ], and should be found not guilty.
A defendant acts under public authority if:
(1) that defendant is affirmatively told that his/her conduct would be lawful;
(2) the defendant is told this by an official of the [United States] government; [and]
(3) the defendant actually relies on what the official tells him/her in taking the action[; and,
(4) the defendant's reliance on what he/ she was told by the official is reasonable in light of the circumstances].
In considering whether a defendant actually relied on representations by an official that his/her conduct would [be] lawful, you should consider all of the circumstances of their discussion, including the identity of the official, the point of law discussed, the nature of what the defendant told, and was told by, the official, and whether that reliance was reasonable.
Seventh Circuit Pattern Criminal Jury Instr. 6.07 (1999).
. Although the facts of
Dixon v. United States,
- U.S. -,
. The principal distinction between justification and excuse lies in the concerns animating the affirmative defense. See 2 Wayne R. LaFave, Substantive Criminal Law § 9.1(a)(4) (2d ed.2003) [hereinafter "LaFave”]. Justification affirmative defenses focus on special circumstances under which the harm caused by the defendant’s actions is outweighed by the risk of a greater harm. Id. § 9.1(a)(3). Such defenses include self-defense, defense of others and necessity. See Paul H. Robinson, Criminal Law Defenses: A Systematic Analysis, 82 Colum. L.Rev. 199, 242 (1982) [hereinafter "Robinson”]. Affirmative defenses of excuse, on the other hand, rest on the conclusion that, because of a particular disability or impairment, it is inappropriate to hold the defendant criminally responsible for the otherwise unlawful conduct. See LaFave § 9.1(a)(4). Duress, somnambulism, infancy and mistake are all examples of defenses grounded in excuse. See Robinsion at 242-43.
. A closely related affirmative defense is the defense of entrapment by estoppel, an affirmative defense also grounded in the Due Process Clause of the Fifth Amendment. Entrapment by estoppel provides an affirmative defense for action taken in reasonable reliance on assurances by government officials that the conduct is legal.
See United States
v.
Howell,
. We shall assume that the district court's failure to instruct the jury that Mr. Jumah had the burden to prove the public authority defense by a preponderance of the evidence was error. Although "[a] defendant is entitled to have the jury consider any theory of defense supported by law and evidence,” he is not entitled to any particular jury instruction regarding that theory.
United States v. Mutuc,
The instruction that Mr. Jumah now contends that the district court should have given the jury is a correct statement of the law
*877
under the Supreme Court's decision in
Dixon.
As our earlier discussion demonstrates,
Dixon
makes clear that the defendant has the burden of establishing the public authority defense by a preponderance of the evidence.
See Dixon,
We also shall assume, for purposes of the present analysis, that the district court correctly concluded that the public authority defense was fairly raised by the evidence at trial. Likewise, the requested instruction was not part of the charge to the jury, and no other instruction addresses Mr. Jumah’s burden with respect to the public authority defense.
