Defendant-appellant Stephen A. Holmquist appeals his convictions on six counts of importing firearms by means of false statements in violation of 18 U.S.C. § 542 and three counts of exporting restricted firearms in violation of 22 U.S.C. § 2778. Holmquist’s case has a certain labyrinthine quality. Having successfully negotiated the maze, however, we find appellant’s claims to be without legal merit and, therefore, affirm the judgment below.
I. BACKGROUND
Appellant, a resident of Massachusetts, owned and operated ARMCO, a firm engaged in the retail sale of firearms. Apparently not content with the domestic market, and believing his entrepreneurial skills to be of sufficient caliber, appellant set his sights on the international scene. Between 1989 and 1991, he conducted several business transactions with individuals in the People’s Republic of China. Since these transactions triggered the indictment in this ease, we offer an overview of them. Where appropriate, we resolve evidentiary conflicts, and indulge reasonable inferences, in a manner compatible with the jury verdict.
See, e.g., United States v. Maraj,
In May of 1989, the U.S. State Department granted appellant’s request for a license to export handguns to the People’s Republic of China. However, following the tragic events that rocked Tiananmen Square in June of that year, the State Department declared that most firearms no longer could be exported to China. At the same time, the Department revoked or suspended all existing export licenses (including appellant’s) and declared a moratorium on the issuance of new licenses. When appellant thereafter sought just such a license, the State Department sent back his application, unapproved and stamped “returned without action.” Appellant did not reapply.
Despite the lack of a license or other formal authorization, appellant thrice smuggled restricted firearms to China between October 1989 and July 1990. He carried the weaponry on commercial flights out of Boston, nestled in his suitcases amidst other, more orthodox travel items. After arriving in China, appellant delivered the guns to either Mr. Ha, a high-ranking government official, 1 or Andrew Wong, a business executive. Based on the evidence anent these transactions, the jury convicted appellant on three counts of unlawful exportation.
China also served appellant as a source for importing firearms and ammunition into the United States. These importations, though not in themselves unlawful, ultimately became so when accompanied by appellant’s apocryphal statements concerning the value of his wares. On six different occasions during 1990 and 1991, appellant undervalued imports, presumably to reduce the duty due. The prosecution was able to adduce virtually irrefutable proof of this duplicity: dual sets of invoices, one containing the price disclosed to Customs and the other containing the actual, higher price that appellant in fact had paid. Based on this well-documented pattern of deceit, the jury convicted appellant on six *158 counts of entering goods by means of false statements.
II. THE IMPORT CHARGES
Taking matters in reverse chronological order, we turn first to an examination of the import charges. These counts arise under a criminal statute that provides in pertinent part:
Whoever enters or introduces, or attempts to enter or introduce, into the commerce of the United States any imported merchandise by means of any fraudulent or false invoice, declaration, affidavit, letter, paper, or by means of any false statement, written or verbal, or by means of any false or fraudulent practice or appliance, or makes any false statement in any declaration without reasonable cause to believe the truth of such statement, or procures the making of any such false statement as to any matter material thereto without reasonable cause to believe the truth of such statement, whether or not the United States shall or may be deprived of any lawful duties ... [s]hall be [punished as provided].
18 U.S.C. § 542 (emphasis supplied). 2
Appellant does not deny that he knowingly made false statements to Customs officials, thereby undervaluing his imports. Nonetheless, he contends that such statements do not fall within the scope of the statute of conviction because the phrase “by means of’ indicates that no violation occurs unless the merchandise, absent the false invoice, statement, or practice, would have been excludable. And he says this was not the case regarding the Chinese munitions, as their importation was lawful. The government, by contrast, puts no stock in a causation requirement, dismissing appellant’s argument as involving too cramped a reading of the statutory language. Because the parties’ dispute boils down to a pure question of statutory interpretation, our review is plenary.
See United States v. Gifford,
Whatever shadows cloud this record, one thing is very clear: even though no materiality requirement appears on the statute’s face, section 542’s first provision must be read to contain such a requirement; to justify a conviction, the prosecution must demonstrate that the false invoice, statement, or practice is related to the importation in some material respect. This is the construction recognized by virtually every court that has directly addressed the issue.
See, e.g., United States v. Corcuera-Valor,
Yet, our recognition of a materiality requirement does not solve the interpretive riddle that this appeal presents; it is the nature of the materiality requirement — not its mere existence — over which the parties grapple. Appellant invites us to hold that materiality in this context is contingent on a crabbed construction of the term “by means of.” Specifically, he argues that “by means of’ is synonymous with “because of,” and that a false statement is material under the first part of section 542 only if the importation of any particular item would have been *159 forbidden in its absence. We decline the invitation.
In discerning the meaning of this portion of section 542, “[w]e start — as all statutory construction must start — by looking at the language of the law,”
United States v. Charles George Trucking Co.,
There is no basis for rejecting plain meaning here. Indeed, contrary to appellant’s importuning, the principal problem with the “by means of’ language is not ambiguity — its meaning is obvious — but, rather, the language’s potential breadth. It is because of this problem that courts have read a materiality requirement into this portion of section 542. This requirement is intended to flesh out, not to eviscerate, the “by means of’ language as that phrase resonates in the context of section 542. So viewed, it brings to the textual surface the commonsense notion that, to ground a conviction, there must be a significant nexus between the false statement and the importation.
We hold, therefore, in basic agreement with the Third Circuit, that a false statement is material under section 542 if it has the potential significantly to affect the integrity or operation of the importation process as a whole, and that neither actual causation nor actual harm to the government need be demonstrated.
See Bagnall,
It is thus apparent that the focus of an inquiry into materiality is not what effect a false statement actually may have, but whether it carries a serious potential risk for obstructing the agency or substantially inhibiting the agency’s performance of its duties under the law. Transplanted to the Customs milieu, a statement is material if it has the potential significantly to affect the integrity or operation of the importation process — the manner in which Customs handles the assessment of duties and passage of goods into the United States.
Having distilled the plain meaning of the disputed phrase, we could end our inquiry at this point.
See, e.g., Charles George Trucking,
An examination of precedent reveals that we already have rejected a narrow, causally oriented reading of the materiality requirement found in the civil analog to section 542.
See Ven-Fuel,
A broad construction of section 542 is also supported by accepted canons of statutory construction. If the first provision in section 542 is construed as applying only to ineligible imports, then the final sentence of the section, discussing the legal irrelevance of depriving the government “of any lawful duties,” would be meaningless (for nonimportable items are not dutiable, and hence, the government could never be deprived). Accordingly, such a construction would transgress the oft-stated interpretive rule that “[a]ll words and provisions of statutes are intended to have meaning and are to be given effect, and no construction should be adopted which would render statutory words or phrases meaningless, redundant or superfluous.”
Ven-Fuel,
Finally, a statute must be read as a whole, with due regard for its object, purposes, and underlying policy.
See Pilot Life Ins. Co. v. Dedeaux,
To recapitulate, we hold that materiality is, in fact, an element of the offense of conviction. This element serves to explain, not to emasculate, the “by means of’ language contained in the first part of the statute. Particularly when viewed against this backdrop, appellant’s proposed equation of “by means of’ with “because of’ betrays both common meaning and common sense. By limiting the scope of section 542’s first provision to ineli *161 gible items, such an interpretation would effectively convert the provision into an inoperative piece of parchment. Accordingly, we reject appellant’s narrow construction, and rule that, in this context, “material” means having the potential significantly to affect the integrity or operation of the importation process as a whole, without regard to whether the conduct at issue caused the importation and without regard to whether the federal government suffered actual harm.
Appellant’s false statements had this deleterious potential. Undervaluations are by their nature materially related to the importation process, both because they may interfere with the government’s efforts to monitor and regulate the flow of goods into the United States and because they undermine the integrity of the entire importation process. Consequently, appellant’s convictions under section 542 must be upheld. 5
III. THE EXCLUDED EVIDENCE
We turn now to appellant’s assertion that his convictions under the Arms Export Control Act, 22 U.S.C. § 2778, are tainted because the trial court excluded evidence— evidence that we sometimes shall call “contacts evidence” — that would have established a defense of apparent public authority 6 and/or negated the element of specific intent. For the reasons explained below, we find this assertion unavailing.
A. Proceedings Below.
Because the precise course of proceedings before and during the trial is critical to the resolution of appellant’s challenge, we rehearse the pertinent details. Between April 27 and May 6,1992, appellant served subpoenas duces tecum on three persons — an agent of the Naval Intelligence Service, the keeper of records at the National Security Agency, and a business associate (whom we shall call “John Doe”) who had accompanied appellant on his excursions to China — proposing to ensure their availability as witnesses at his trial. Appellant alleged that Doe (who, he said, was in the employ of a federal intelligence agency) had authorized the arms exports. 7 It was appellant’s legal theory that, even if Doe were not a spy, Doe’s imprimatur could undermine the government’s case against appellant either by providing a defense of apparent public authority, but see supra note 6, or by negating an element of the offense, namely, specific intent.
The government responded by filing motions to quash the subpoenas, followed on May 18 by both a memorandum of authorities and an ex parte submission pursuant to the Classified Information Procedures Act, 18 U.S.C. app. III (CIPA), which limns a procedure permitting classified information “to be inspected by the court alone.” Id. § 4. On the same date, appellant made an oral ex parte proffer to the trial court, explaining the relationship between the subpoenas and his proposed trial strategy.
On May 21, following an in camera hearing, Judge Keeton granted the government’s motions to quash. He also granted the government’s oral motion in limine, made in anticipation that appellant might renew his efforts to proffer contacts evidence. When reduced to writing on May 26, 1992, the in limine order required appellant, before *162 “fil[ing] or disclosing] any document, asking] any question, or making] any statement related to any alleged contact between any individual and any intelligence agency,” to “first present[ ] such matter directly to the [trial judge] in chambers or at sidebar and ... receive[ ] from [the judge] a ruling allowing the requested action....”
Immediately prior to trial, appellant filed a motion to reconsider these rulings, accompanied by a written, sworn ex parte proffer. After a hearing that began on October 22, 1992, and continued into the next day, the district court denied the motion. Trial commenced a few days later.
At trial, appellant called only one witness, a Customs agent, and made no discernible effort to capitalize on the court’s invitation to examine his purported contacts evidence in camera. 8 Still, at the close of his case appellant moved for a mistrial, claiming that the district court’s pretrial rulings denied him the opportunity to present a robust defense. The court spurned the motion. In due course the jury convicted appellant on all three exportation counts (as well as on the charges of unlawful importation discussed in Part II, supra).
B. Analysis.
Appellant contests the district court’s pretrial rulings — specifically, the orders entered in respect to the government’s motions to quash and motion in limine — on the theory that those rulings precluded him from presenting to the jury a complete and competent defense. He assails the district court’s denial of his motion for a mistrial for much the same reason. In particular, he alleges that these rulings — which for our purposes coalesce into, and are subsumed by, the order in limine 9 — transgressed his rights under both the Due Process Clause of the Fifth Amendment and the Compulsory Process Clause of the Sixth Amendment by foreclosing him from mounting a defense to the charges. Having carefully deterrated the record, we find that this challenge has not been properly perfected and, therefore, evaporates into thin air.
On appeal, Holmquist claims that the contacts evidence bore on two possible lines of defense: (1) that he acted on Doe’s instructions, and, hence, under the guise of apparent public authority — a defense that, in any event, would have misfired,
see supra
note 6; and (2) that he lacked the requisite specific intent to commit the charged crime — a strategy that, at least in theory, had promise,
see, e.g., United States v. Murphy,
Based on the overall record, appellant might well be deemed to have abandoned the specific intent theory. As we have previously admonished, “[a] party has a duty to put its best foot forward ... [and] to spell out its arguments squarely and distinctly.”
Paterson-Leitch Co. v. Massachusetts Mun. Wholesale Elec. Co.,
Although the question of abandonment is close, we need not resolve it, for at the trial itself, appellant eschewed any attempt to offer evidence in camera in accordance with the district court’s express invitation and the provisional nature of the court’s in limine ruling. 11 The government maintains that, given this omission, appellant no longer can contest the operation of the court’s order in limine. We agree. Appellant’s snubbing of the court’s invitation to consider evidentiary offerings during the trial effectively insulated from appellate review any complaints he voiced in connection with the court’s pretrial evidentiary rulings. In the pages that follow, we explain our rationale.
It is a bedrock principle of our adjudicatory system that ostensible errors arising before and during trial must be properly raised and preserved in order to be reviewable on appeal.
See United States v. Griffin,
In entering the
in limine
order below, Judge Keeton made it clear that the only definite limitation on appellant’s ability to introduce contacts evidence was that he must first present it out of the jurors’ earshot, that is, to the judge, either in chambers or at sidebar. Federal district judges enjoy broad discretion in respect to the ordering and presentation of proof and the handling of evidentiary questions.
See, e.g.,
Fed.R.Evid. 104(c) (stating that hearings on preliminary matters other than the admissibility of confessions may be conducted out of the hearing of the jury “when the interests of justice require”); Fed.R.Evid. 611(a) (empowering district courts to exercise “reasonable control” over mode and presentation of evidence);
see also Luce v. United States,
It follows inexorably that, since the
in limine
order represented a lawful exercise of judicial power, appellant’s failure to abide by its terms bars him from complaining in this venue about evidence that could have been—
*164
but was not — proffered to the court within the framework of the order. After all, the trial judge’s offer to consider proposed evi-dentiary offerings
in camera,
as the occasion arose, was not a mere formality — and appellant treated it as such at his peril.
See Conway v. Electro Switch Corp.,
Our conclusion rests not only upon the fundamental principles of judicial economy and attorney cognizance, but also upon a well-defined corpus of federal appellate case law. The touchstone, of course, is the Court’s decision in
Luce.
The
Luce
Court held specifically that a defendant who chooses not to testify at trial loses his right to appeal the district court’s ruling denying his
in limine
motion to forbid the impeachment use of a prior conviction.
See Luce,
In the instant case, both of these concerns are implicated. Regarding the reviewability concern, it is precisely because appellant comes before us not having attempted to offer evidence during the trial that we cannot rule intelligently on the underlying evidentia-ry questions; he presents us with an abstract intellectual exercise, rife with conjecture, rather than affording us an opportunity to inspect concrete evidence, offered and excluded in an actual trial context. Regarding the exploitation concern, we likewise have no reliable way of knowing whether appellant’s decision to forgo the trial judge’s invitation reflected a genuine sense of preclusion, a mere oversight, an ill-fated stratagem (such as an attempt to infect the trial with error), or simply a realization that the putative contacts evidence was not likely to be helpful after all.
Our conclusion that appellant did not sufficiently perfect a right to appeal in respect to contacts evidence draws further support from the myriad cases that have seen fit to extend the tenets of
Luce
into other contexts involving
in limine
motions.
See Griffin,
Two years after
Griffin,
we had another opportunity to apply the principles of
Dace,
this time to a case involving an anticipatory motion to limit cross-examination of the defendant.
See United States v. Nivica,
Because Nivica did not take the stand, or ask for voir dire, his exact testimony remains, in the Luce phrase, “unknowable.” The alleged harm is “wholly speculative,” both because (a) the judge, in the give-and-take of live testimony, might have changed his mind and confined cross-examination more closely, and (b) on this record, we have no way of knowing the extent to which the government would have sought to cross-question Nivica (if at all) about other matters. Moreover, in this case as in Luce, there is no reliable method for divining the genesis of defendant’s decision not to testify.... Furthermore, were we to relax the rule, we would run the very risk — ease in “ ‘plant[ing]’ reversible error” — that the Luce Court aimed to avoid. Finally, defendant’s tactical choice in this case, as in Luce, has thwarted our ability to judge the harmfulness of the asserted error.
Id.
at 1116-17 (citations omitted). In the bargain, we rejected defendant’s claim that, because the trial judge ruled as a matter of law rather than expressly labelling his ruling as conditional,
Luce
should not have governed the analysis. We emphasized that the critical dimensions of a
Luce
scenario include timing and context, and that, “Ultimately, the trier’s decision, whatever his initial inch-nation, had to depend upon particular questions and their relation to the content of the direct examination.”
Id.
at 1117. In the same way, appellant in the case before us inexplicably declined the opportunity to probe the trial judge’s provisional ruling by making a concrete proffer in a five context, thus depriving this court of the opportunity meaningfully to review his claim.
Cf. Reilly v. United States,
We also find instructive the experience of the Seventh Circuit, which recently confronted a situation quite similar to this one. In
United States v. Addo,
[T]he ball was in the defendant’s court to challenge the granting of the motion in limine. For some reason, the defense failed to respond to the judge’s ruling again during the trial. This may have been an oversight on the part of defense counsel in the midst of a busy trial or a *166 well-calculated trial strategy. Whatever the reason, the record reflects that the defense was clearly given the opportunity to raise the matter again before the trial judge and failed to do so. Accordingly, the defense may not challenge the merits of this ruling on appeal.
Id.
at 242;
see also Favala v. Cumberland Engin’g Co.,
These principles and precedents necessarily control our decision in this ease. The district judge’s ruling was patently provisional. The court gave appellant ample opportunity to reiterate his request to introduce evidence of purported government contacts in the context of the actual trial. For whatever reason, appellant chose not to take up the gauntlet. One consequence of appellant’s inertia is that we, as an appellate tribunal, can only engage in rank speculation about whether the trial judge would have allowed appellant to introduce specific evidence (the exact nature of which is unknown to us, see swpra note 8) for a specific purpose (the exact nature of which is likewise unknown to us) had he attempted to do so during the trial. An appeal that asks a reviewing court to decide delicate questions of evidentiary error based not on a tangible, well-defined record, but rather on conjecture and surmise, does not deserve a favorable answer.
For these reasons, we conclude that, when a judge issues a provisional in limine pretrial order and clearly invites the adversely affected party to offer evidence at sidebar for the purpose of reassessing the scope or effect of the order in the setting of the actual trial, the exclusion of evidence pursuant to that order may be challenged on appeal only if the party unsuccessfully attempts to offer such evidence in accordance with the terms specified in the order. 12 Because appellant failed to follow this well-marked path, we hold that he cannot now complain about the trial court’s handling of the contacts evidence.
IV. OTHER EVIDENTIARY ISSUES
In his final assignment of error, appellant suggests that the district court erred in permitting the prosecution to introduce, over *167 objection, certain items of evidence that, appellant says, were not satisfactorily authenticated. The challenged evidence comprises a photocopy provided by Andrew Wong (a purchaser of unlawfully exported firearms), and snapshots of weapons displaying serial numbers matching for the most part those listed on weapons in appellant’s inventory. In addition to questioning authentication, appellant also claims that, in all events, the photocopy should have been excluded as hearsay. We believe that this fusillade misses the mark.
A. The Photocopy.
In respect to the photocopy, we treat appellant’s authentication and hearsay challenges separately.
1. Authentication. Exhibit 17A purported to be a photocopy of a bank check in the amount of $2500, drawn on the Bank of China at Hong Kong, bearing a date of December 20, 1988, and made payable to appellant. To authenticate the proffer, Dennis Kelly, a Customs agent, testified that Wong provided him, via air courier from Hong Kong, with both the photocopy and a three-page invoice in appellant’s handwriting. This document, admitted into evidence at trial as Exhibit 17, described, among other things, a $2500 credit in Wong’s favor. 13
Appellant argues that the proof failed to eliminate a googol of possibilities concerning the photocopy, e.g., that it was a fake, or that the check was made at some time other than the stated date, or that it was never delivered to appellant, or, if delivered, that it was never negotiated. Additionally, appellant argues that a finding of authenticity could not readily be based on material emanating from Wong because Wong had soured on him and was, therefore, a biased source.
It cannot be gainsaid that documentary evidence must be authentic. The test of authenticity is straightforward: “The requirement of authentication or identification as a condition precedent to admissibility is satisfied by evidence sufficient to support a finding that the matter in question is what its proponent claims.” Fed.R.Evid. 901(a);
see also United States v. Paulino,
There is no single way to authenticate evidence. In particular, the direct testimony of a custodian or a percipient witness is not a
sine qua non
to the authentication of a writing.
See Paulino,
Issues of authentication are almost always fact-sensitive. Consequently, when such issues arise, the trial court must act as a gatekeeper.
See United States v. Ladd,
Here, the district court noted that the purported bank check was dated “Dee. 20, 1988”; that it was payable to “Steve Holm-quist”; and that it was for $2500. The court also determined that Exhibit 17 (the three-page invoice in appellant’s handwriting) strongly corroborated Exhibit 17A; after all, agent Kelly received the invoice in the very same package as the photocopy of the check, and the invoice mentioned a $2500 credit to Wong, thereby lending considerable credence to the proposition that Holmquist received a payment (the bank check), acknowledged its receipt, and credited Wong’s account in the *168 amount of the payment. 14 Given the totality of the circumstances, especially the ties binding Wong to Holmquist, we agree with the lower court that a jury could draw reasonable inferences connecting the photocopy of the bank check to the invoice.
To be sure, appellant’s objections are not entirely without force. It is
possible
that the photocopy had been doctored, or constituted an instrument through which Wong, for whatever reason, aspired to carry out an elaborately staged hoax. But the burden of authentication does not require the proponent of the evidence to rule out all possibilities inconsistent with authenticity, or to prove beyond any doubt that the evidence is what it purports to be. Rather, the standard for authentication, and hence for admissibility, is one of reasonable likelihood.
See United States v. McGlory,
Here, mindful of the deference accorded to the trial court’s exercise of its discretion, we cannot say that the court erred in declaring the photocopy of the bank check to be sufficiently authenticated, or in admitting it into evidence.
2. Hearsay. Appellant also suggests that, because the photocopy was introduced to prove the truth of the matter asserted, it was hearsay and, therefore, inadmissible unless it fell within one of the exceptions to the hearsay rule. We need not probe this point too deeply, for close perlustration of the record makes it plain that appellant never advanced this objection below.
During the trial, appellant made a cluster of objections with regard to the photocopy of the bank check. However, these objections focused on authentication, and contained no developed argumentation in regard to hearsay principles. To be sure, defense counsel at one point called the photographs “totem pole hearsay,” and, in a later colloquy, applied the same epithet to the photocopy. But we think that this elliptical reference carries little weight. Under prevailing federal practice, objections to evidentiary proffers must be reasonably specific in order to preserve a right to appellate review.
See, e.g., United States v. Walters,
The rule is not a mere technicality, but is solidly grounded in considerations of fairness and judicial economy. As we said in
Walters,
B. The Photographs.
The district court also permitted the prosecution to introduce nine photographs purporting to depict firearms that appellant illegally exported to China. Each *169 photograph showed the serial number on the weapon portrayed therein. In the main, these serial numbers matched two other sets of serial numbers: the serial numbers of firearms that were transferred from AKM-CO’s inventory to appellant, and the serial numbers listed in wire transmissions from appellant to Wong. Agent Kelly testified that he received these photographs during a meeting with Wong in Hong Kong early in 1992.
In admitting the photographs, the district court stated:
[B]ecause serial numbers appear on the photographs and can be compared with the serial numbers on other documents in evidence in this case, it would be an extraordinary inference that the guns that contained those serial numbers could have been assembled at a time before the documents were prepared that are in evidence here.
‡ ‡ ‡ ‡
[A] fact finder may reasonably draw the inference that it’s most unlikely that those guns came into the hands of somebody who could assemble them together, take those photographs and those photographs then came into the hands of the Government agent from some source that would undercut the inference that they were taken over by Steve Holmquist.
Appellant inveighs against this assessment, asserting that the prosecution presented no evidence to show when, where, why, and under what circumstances the photographs were taken. This assertion is true — but it is beside any pertinent point. A photograph’s contents, buttressed by indirect or circumstantial evidence, can form a sufficient basis for authentication even without the testimony of the photographer or some other person who was present at the time it was taken.
See, e.g., United States v. Stearns,
We will not prattle. The lower court’s assessment of the situation is plausible; indeed, it makes abundant sense. Based on it, the court concluded that the photographs were most likely authentic, and permitted their introduction into evidence. We think that this finding falls well within the realm of the court’s discretion.
V. CONCLUSION
We summarize succinctly. As for the importation statute, 18 U.S.C. § 542, appellant’s proposed interpretation of the materiality requirement is simply too restrictive; the better definition is one that accounts for the possible effects of false statements on the importation process as a whole. As for the in limine order, which affects only the export charges, appellant failed to perfect the exclusion-of-evidence challenge he now seeks to advance. Finally, we find no merit in appellant’s complaints about the admission of other evidence.
We need go no further. Appellant’s arguments are legally impuissant and, therefore, his convictions must be
Affirmed.
Notes
. Carrying the adversarial ethic to an extreme, the parties are unable to agree on the spelling of Mr. Ha’s first name; the government spells it Solomon while appellant spells it Soloman. We attempt a Solomonic resolution of the appellative appellate contretemps, eschewing any textual reference to Ha’s given name.
. Complementing this first provision is a second, covering deceptive importations that are designed to deprive the government of duties. Although the prosecution in this case may have missed the bull's-eye by charging appellant under the first, rather than the second, of section 542’s provisions, the government is bound by its charging decision. Consequently, the proviso we have quoted governs here.
. Indeed, although the precise issue was not before us, we commented favorably upon our perception that “under 18 U.S.C. § 542, criminal convictions have regularly been sustained where generically importable goods had been entered by trick or artifice.”
Ven-Fuel,
. To be sure, two courts of appeals, the Fifth and the Ninth, have reached the opposite conclusion.
See Corcuera-Valor,
. Appellant also assigns error to the district court's jury instructions on the importation counts. This assignment of error is constructed around the same misinterpretation of section 542’s materiality requirement. It, therefore, fails.
. The "defense” of apparent public authority is a defense based on a mistaken but good-faith belief that one’s conduct is authorized by the government. Appellant's repeated references to this defense constitute little more than a school of red herrings. The defense is not a defense at all.
See United States v. Duggan,
.The nonexistent defense of apparent public authority,
see supra
note 6, must not be confused with the potentially viable defense of actual public authority, which may come into play when a defendant undertakes certain acts, reasonably relying on the statements of a government agent cloaked with actual authority.
See United States v. Baptista-Rodriguez,
. Even if we give appellant the benefit of his description of it, the contacts evidence is entropic at best. Apart from the claims about what Doe ostensibly said, the contacts evidence consists entirely of gauzy generalities, inadmissible double hearsay, and unsupported suppositions.
. Because appellant’s subpoenas sought the production of evidence at trial, the district court's order in limine effectively controlled, and therefore subsumed, the quashal order. By like token, the district court's denials of appellant’s eve-of-trial motion for reconsideration and mid-trial motion for a mistrial lack independent significance; if the court committed no antecedent error in the exclusion of evidence under the aegis of the order in limine, then those motions were bootless. Thus, our analysis of this assignment of error may appropriately focus upon the order in limine alone.
.There is also some suggestion that appellant considered raising a defense of estoppel by entrapment.
See United States v. Smith,
. The transcript reflects only one point in the trial at which appellant requested a sidebar for the purpose of attempting to introduce evidence related to the order in limine — and on that lone occasion, the district court granted appellant's request. This demonstrates quite vividly an awareness on appellant's part that the court had left the door open to proffers of such evidence.
. This rule is not without limits. For example, it will not apply when the
in limine
order is itself final. Finality may inhere either in the nature of the judge’s words, or in the rationale of his ruling, or in both.
See, e.g., Fusco v. General Motors Corp.,
. On appeal, Holmquist does not contest the admission of Exhibit 17 as a full exhibit.
. The handwritten invoice used the words "minus $2500, 12/29/88.”
. Of course, even without a sufficient objection, appellant can obtain relief on appeal if the admission of the so-called “hearsay evidence” sinks to the level of plain error.
See Griffin,
