    .
    In the amended opinion, the panel reversed and remanded
    to the district court so that it may enter a judgment of
    acquittal on the obstruction of justice charges and resentence
    defendant Johnson.

    OPINION
    O’SCANNLAIN, Circuit Judge:
    We must decide whether an FBI investigation qualifies as
    an “official proceeding” under a federal statute criminalizing
    obstruction of justice.
    I
    A
    The facts of this case read like an episode of the fictional
    television drama Sons of Anarchy.1 Sometime in 2006, the
    Central Valley Gang Impact Task Force (“CVGIT”)—a
    United States Department of Justice (“DOJ”)-funded group
    tasked with coordinating local law enforcement efforts to
    eliminate gang-related crimes in California’s Central
    Valley—learned that the Hells Angels motorcycle gang was
    attempting to establish a chapter in Modesto, California.2
    Hoping to disrupt the formation of this gang chapter, the
    CVGIT opened an investigation into several known
    associates of the Hells Angels gang in the Modesto area,
    1
    Sons of Anarchy is a television drama series that runs on the cable
    channel FX. It documents the legal and illegal activities of a fictional
    outlaw motorcycle club operating in a town in California’s Central Valley.
    In the show, the club’s headquarters are located in a clubhouse adjacent
    to an auto mechanic shop.
    2
    The Federal Bureau of Investigation (“FBI”) was also a member-
    agency of the CVGIT. Because FBI Agent Nathan Elias was the lead
    member of the CVGIT task force investigating the Holloways, we—like
    the parties—will refer to the CVGIT’s investigation as an FBI
    investigation.
    UNITED STATES V. ERMOIAN                           5
    including Robert Holloway and his son Brent Holloway,3 the
    Road Dog Cycle Shop (which they co-owned), and members
    of the Merced Chapter of the Hells Angels gang who were
    affiliated with Road Dog Cycle.
    Through information gleaned from earlier investigations,
    the CVGIT was aware that Road Dog Cycle was dealing in
    stolen motorcycles and motorcycle parts. The task force also
    suspected that some individuals associated with law
    enforcement were leaking information to the Holloways and
    were thus facilitating their criminal enterprise.
    To catch the Holloways engaging in illegal activity, the
    CVGIT first sought to prevent any further leaks of
    confidential law enforcement information. Thus, in an effort
    to ferret out some of Robert’s law enforcement sources, the
    CVGIT created a “Gang Intelligence Bulletin,” which it
    distributed to local law enforcement in September 2007. The
    bulletin purported to contain “confidential information” that
    was “intended for law enforcement personnel only.” But in
    actuality, the information in the bulletin was “watered down”
    to avoid leaks of sensitive information that could truly
    jeopardize the CVGIT’s investigation into the Holloways and
    Road Dog Cycle. In substance, the bulletin described
    surveillance of the annual summer “Burn-Out Party” held at
    Road Dog Cycle and named the different outlaw motorcycle
    gangs seen in attendance. After circulating the bulletin, the
    CVGIT monitored wiretaps it had placed on Robert’s phones,
    hoping to ensnare the law enforcement officers leaking
    information.
    3
    To avoid confusion, we refer to Robert and Brent Holloway by their
    first names.
    6                 UNITED STATES V. ERMOIAN
    The defendants in this case, Gary L. Ermoian and Stephen
    J. Johnson, were charged with obstructing justice based upon
    their activities during a chain of events set into motion by the
    bulletin’s distribution. The morning after the Gang
    Intelligence Bulletin was distributed to law enforcement
    personnel, David A. Swanson4—a Deputy Sheriff and bailiff
    in the county courthouse—placed a 40.8 second phone call
    from his work telephone to Ermoian. At the time,
    Ermoian—one of Robert’s close personal friends—was
    employed as a part-time private investigator for Robert’s
    attorney, Kirk McAllister. Swanson informed Ermoian that
    he “saw some photos” of the Burn-Out Party and that
    Ermoian should warn Robert to “watch his back.”
    The wiretap on Robert’s phone recorded a flurry of
    activity immediately after Swanson contacted Ermoian. Just
    minutes after receiving the call from Swanson, Ermoian
    called Robert to share Swanson’s tip. Given Swanson’s
    position in the courthouse and his access to information about
    pending warrant applications, Ermoian was concerned that
    Swanson’s veiled warning that Robert should “watch his
    back” might indicate that police were coming with a search
    warrant. He thus advised Robert to “take a look around the
    shop [to] see if you see anything . . . .” Heeding Ermoian’s
    advice, Robert talked to Brent and other Road Dog Cycle
    employees, checked the store for “questionable” motorcycle
    parts, and put one questionable item “in the alley [behind the
    store] with a tag on it.”
    4
    Although Swanson was charged with obstruction of justice and was
    tried along with defendants Ermoian and Johnson, he was acquitted of the
    charge. Thus, he is not a party to this appeal.
    UNITED STATES V. ERMOIAN                     7
    Later that same day, Ermoian and Robert both received
    several additional phone calls warning about a pending
    investigation into Road Dog Cycle from defendant Johnson.
    Johnson was not a member or close affiliate of the Hells
    Angels motorcycle gang, but he had become acquainted with
    Robert, Ermoian, and McAllister through a business he
    owned and operated, which subcontracted with law
    enforcement to perform canine sniff searches. Starting
    sometime in 2006, Robert and his attorney McAllister had
    hired Johnson on a few occasions to perform preventative
    canine searches of Road Dog Cycle so that they could locate
    and dispose of any drugs or other contraband found on the
    premises. Shortly after Ermoian received Swanson’s tip,
    McAllister requested that Johnson perform a preventative
    search of Road Dog Cycle in anticipation of the pending law
    enforcement raid. Upon learning that another source
    suspected a raid, Johnson informed both Ermoian and Robert
    that he had “overheard” a conversation at the DOJ facility
    where he was contracted to conduct periodic canine searches
    about an impending Bureau of Alcohol, Tobacco, and
    Firearms (“ATF”)-DOJ investigation into Road Dog Cycle.
    With two sources suggesting that a police raid was
    imminent, Robert, Ermoian, Johnson, and other affiliates of
    Road Dog Cycle flew into action. Based on the wiretap, the
    CVGIT learned that they conducted counter-surveillance,
    searching for undercover officers near the shop. They warned
    the local chapter of Hells Angels to “make sure that [the]
    crew is safe” because they were in “jeopardy” from law
    enforcement crackdowns. They attempted to ferret out
    informants within the motorcycle gang. And they generally
    tried to “make sure that all [their] ducks [we]re in a row” and
    made an effort to be “careful about what c[ame] in and out”
    of the shop.
    8               UNITED STATES V. ERMOIAN
    Having discovered that Ermoian and Johnson were related
    to the law enforcement information leaks, the CVGIT did not
    move immediately to arrest them. Instead, to avoid tipping
    off the other suspects to the true scope of the investigation, it
    postponed action and continued to dig into the illegal
    activities of Robert and Road Dog Cycle, as they were the
    primary targets of the investigation. It wasn’t until June
    2008, when the CVGIT’s investigation into the Holloways
    was coming to a close, that FBI Agent Nathan Elias—the lead
    member of the CVGIT for the Holloway case—first went to
    interview Ermoian about the Holloway investigation.
    Johnson was first interviewed about his involvement with
    Holloway a month later. Subsequently, both Ermoian and
    Johnson were arrested on charges of conspiracy to obstruct
    justice.
    B
    On May 28, 2009, a federal grand jury returned an
    indictment against twelve defendants associated with Road
    Dog Cycle, charging several violations of racketeering laws
    and various related offenses. In the indictment, defendants
    Ermoian and Johnson were charged with conspiracy to
    “corruptly obstruct, influence, and impede an official
    proceeding, to wit, a law enforcement investigation
    conducted by the Federal Bureau of Investigation” in
    violation of 
    18 U.S.C. § 1512
    (c)(2), (k). Defendants Ermoian
    and Johnson, and the charges against them, were severed
    from the other defendants and charges in the indictment. The
    remaining defendants pleaded guilty to various charges, and
    only Ermoian and Johnson proceeded to trial.
    Throughout the trial process, Ermoian and Johnson
    challenged the legal validity of the obstruction of justice
    UNITED STATES V. ERMOIAN                       9
    charge. Specifically, and relevant to this appeal, the
    defendants filed a pre-trial motion to dismiss the indictment,
    an objection to the jury instructions and a motion for acquittal
    during trial, as well as a post-trial motion for acquittal, at all
    times asserting the same general argument: they could not be
    convicted under the obstruction of justice statute, § 1512,
    because their alleged obstruction of an FBI investigation did
    not qualify as obstruction of an “official proceeding” under
    the statute. The district court rejected this argument each
    time, concluding that the term “official proceeding” as used
    in the statute should be read broadly to include an “FBI
    investigation.”
    The jury convicted Ermoian and Johnson of obstructing
    justice. They timely appealed.
    II
    Ermoian and Johnson raise various arguments challenging
    their conviction on appeal, but they focus primarily on one
    issue: Did the district court err when it determined that an
    FBI investigation qualifies as an “official proceeding” under
    the statute criminalizing obstruction of justice?
    Our circuit has never before addressed the meaning of the
    term “official proceeding” as used in the obstruction of
    justice statute at 
    18 U.S.C. § 1512
    . But the dearth of Ninth
    Circuit case law on the question does not leave us without a
    point of reference. We begin, as any effort to interpret a
    statute must, with the text. The “first step in interpreting a
    statute is to determine whether the language at issue has a
    plain and unambiguous meaning with regard to the particular
    dispute in the case.” Robinson v. Shell Oil Co., 
    519 U.S. 337
    ,
    340 (1997). Whether the meaning of a statute is plain “is
    10              UNITED STATES V. ERMOIAN
    determined by reference to the language itself, the specific
    context in which that language is used, and the broader
    context of the statute as a whole.” 
    Id. at 341
    . If the statute’s
    meaning can be resolved by reference to the statutory text
    such that “the statutory language is unambiguous and ‘the
    statutory scheme is coherent and consistent,’” our inquiry is
    complete. 
    Id. at 340
     (quoting United States v. Ron Pair
    Enterprises, Inc., 
    489 U.S. 235
    , 240 (1989)).
    A
    The statute under which the defendants were convicted,
    
    18 U.S.C. § 1512
    (c)(2), prohibits “corruptly . . . obstruct[ing],
    influenc[ing], or imped[ing] any official proceeding, or
    attempt[ing] to do so.” 
    Id.
     (emphasis added). Section
    1515(a)(1) defines an official proceeding as:
    (A) a proceeding before a judge or court of
    the United States, a United States magistrate
    judge, a bankruptcy judge, a judge of the
    United States Tax Court, a special trial judge
    of the Tax Court, a judge of the United States
    Court of Federal Claims, or a Federal grand
    jury;
    (B) a proceeding before the Congress;
    (C) a proceeding before a Federal
    Government agency which is authorized by
    law; or
    (D) a proceeding involving the business of
    insurance whose activities affect interstate
    commerce before any insurance regulatory
    UNITED STATES V. ERMOIAN                      11
    official or agency or any agent or examiner
    appointed by such official or agency to
    examine the affairs of any person engaged in
    the business of insurance whose activities
    affect interstate commerce[.]
    
    18 U.S.C. § 1515
    (a)(1). Of these definitions, the parties
    agree that only one might cover an FBI investigation—“a
    proceeding before a Federal Government agency which is
    authorized by law.” 
    Id.
     § 1515(a)(1)(C).
    1
    As used in the statute, the definition of the phrase
    “official proceeding” depends heavily on the meaning of the
    word “proceeding.”       That word is used—somewhat
    circularly—in each of the definitions for an “official
    proceeding” and is key to the phrase’s meaning. See id.
    “Proceeding” has been defined in various ways, ranging
    from the broad to the specific. But an account of both lay and
    legal dictionaries suggests that definitions of the term fall into
    one of two categories: “proceeding” may be used either in a
    general sense to mean “[t]he carrying on of an action or series
    of actions; action, course of action; conduct, behavior” or
    more specifically as a legal term to mean “[a] legal action or
    process; any act done by authority of a court of law; a step
    taken by either party in a legal case.” Proceeding, Oxford
    English Dictionary, available at http://www.oed.com; see
    also Black’s Law Dictionary 1241 (8th ed. 2004) (defining
    proceeding either narrowly as (1) “[t]he regular and orderly
    progression of a lawsuit, including all acts and events
    between the time of commencement and the entry of
    judgment;” (2) “[a]ny procedural means for seeking redress
    12              UNITED STATES V. ERMOIAN
    from a tribunal or agency;” and (3) “[t]he business conducted
    by a court or other official body; a hearing” or more broadly
    as “an act or step that is part of a larger action.”). As such,
    one of the word’s definitions (“an action or series of actions”)
    is broad enough to include a criminal investigation, as it
    encompasses a wide range of activities. See Proceeding,
    Oxford English Dictionary, available at http://www.oed.com.
    But the other (“any act done by authority of a court of law; a
    step taken by either party in a legal case”) would exclude
    criminal investigations in the field, as it associates the term
    with formal appearances before a tribunal. See id.
    Dictionary definitions of the term “proceeding” alone,
    therefore, cannot conclusively resolve whether an FBI
    investigation qualifies as an official proceeding under § 1512.
    But dictionary definitions in isolation do not end our inquiry.
    When a term has both a general and a more technical
    meaning, we must look to surrounding words and phrases to
    decide which of the two meanings is being used. As it was
    once aptly explained: “Sometimes context indicates that a
    technical meaning applies. . . . And when law is the subject,
    ordinary legal meaning is to be expected, which often differs
    from common meaning.” Antonin Scalia & Bryan A. Garner,
    Reading Law: The Interpretation of Legal Texts 73 (2012).
    Several aspects of the definition for “official proceeding”
    suggest that the legal—rather than the lay—understanding of
    term “proceeding” is implicated in the statute. For one, the
    descriptor “official” indicates a sense of formality normally
    associated with legal proceedings, but not necessarily with a
    mere “action or series of actions.” See 
    18 U.S.C. § 1515
    ; see
    also Proceeding, Oxford English Dictionary, available at
    http://www.oed.com. Moreover, when used to define
    “official proceeding,” the word “proceeding” is surrounded
    UNITED STATES V. ERMOIAN                    13
    with other words that contemplate a legal usage of the term,
    including “judge or court,” “Federal grand jury,” “Congress,”
    and “Federal Government agency.” And most importantly,
    the definition of “official proceeding” at issue here clarifies
    that the type of “proceeding” being described “is authorized
    by law.” 
    18 U.S.C. § 1515
    (a)(1)(C) (emphasis added).
    Thus, clues in the text surrounding “proceeding”—
    although perhaps not conclusive—point us in a general
    direction. And the overall tenor of the definitions associated
    with the legal usage of “proceeding” supports the notion that
    a mere criminal investigation does not qualify as one. See
    Black’s Law Dictionary 1241 (8th ed. 2004). As the
    commentary accompanying that definition succinctly
    explains, “‘Proceeding’ is a word much used to express the
    business done in courts” and “is an act done by the authority
    or direction of the court, express or implied.” 
    Id.
     (quoting
    Edwin E. Bryant, The Law of Pleading Under the Codes of
    Civil Procedure 3–4 (2d ed. 1899)). Indeed, in listing the
    various actions that might qualify as a “proceeding,” in law
    the earliest “ancillary or provisional step[]” adjudged to
    qualify as such was an arrest, which—of course—would
    occur after the criminal investigation had already been
    completed. 
    Id.
     (quoting Edwin E. Bryant, The Law of
    Pleading Under the Codes of Civil Procedure 3–4 (2d ed.
    1899)).
    Thus the definition of the term “proceeding” strongly
    suggests that “a proceeding before a Federal Government
    agency which is authorized by law” does not encompass a
    criminal investigation. See 
    18 U.S.C. § 1515
    (a)(1)(C).
    14                  UNITED STATES V. ERMOIAN
    2
    What the term “proceeding” alone leaves mildly
    ambiguous, the broader statutory context makes entirely
    plain: an “official proceeding” does not include a criminal
    investigation.
    Examining the term “proceeding” within the grammatical
    structure of the definition at issue, it becomes clear that the
    term connotes some type of formal hearing. The statute
    refers to proceedings “before a Federal Government
    agency”—a choice of phrase that would be odd if it were
    referring to criminal investigations. 
    Id.
     The use of the
    preposition “before” suggests an appearance in front of the
    agency sitting as a tribunal. As the Fifth Circuit explained
    when addressing this same definition, “use[ of] the
    preposition ‘before’ in connection with the term ‘Federal
    Government agency’ . . . implies that an ‘official proceeding’
    involves some formal convocation of the agency in which
    parties are directed to appear, instead of any informal
    investigation conducted by any member of the agency.”
    United States v. Ramos, 
    537 F.3d 439
    , 462–63 (5th Cir.
    2008).5 In short, a criminal investigation does not occur
    5
    Although the government cites to two different out-of-circuit decisions
    in an effort to convince us that the term “official proceeding” in the
    obstruction of justice statute should be read broadly to include criminal
    investigations, we are not persuaded by their reasoning. See United States
    v. Kelley, 
    36 F.3d 1118
    , 1128 (D.C. Cir. 1994); United States v. Gonzalez,
    
    922 F.2d 1044
    , 1055–56 (2d Cir. 1991).
    The first, Kelley, did not even analyze the meaning of the term
    “official proceeding” as used in the obstruction of justice statute. Instead,
    the court “assume[d] that the AID Inspector General’s investigation was
    a proceeding under § 1512 . . .” based on an agreement between the
    UNITED STATES V. ERMOIAN                             15
    parties. Kelley, 
    36 F.3d at 1128
    . This assumption carries no persuasive
    weight.
    The second, Gonzalez, addressed the meaning of “official
    proceeding” as it is used in the statutory subsection delineating
    appropriate venue for § 1512 prosecutions. Gonzalez, 
    922 F.2d at
    1054–56. That subsection specifies that venue lies “in the district in
    which the official proceeding (whether or not pending or about to be
    instituted) was intended to be affected.” 
    18 U.S.C. § 1512
    (i). The court
    in that case interpreted the phrase “official proceeding” broadly to
    encompass investigations, because it was concerned that if it were to
    exclude investigations from the scope of the term “official proceeding” in
    the venue provision, then that provision would, in effect, overrule the
    substantive subsections in § 1512. Id. at 1055. Specifically, the court was
    concerned that if the government could not obtain venue where an
    investigation was conducted, then a criminal could not be convicted of
    obstructing “an official proceeding [that was] not . . . pending or about to
    be instituted at the time of the offense” as the statute contemplated. Id. at
    1055–56; see also 
    18 U.S.C. § 1512
    (f)(1).
    We are not persuaded that the Second Circuit correctly analyzed the
    meaning of the term official proceeding in this statute. First, that court
    never carefully parsed the plain meaning of the definition for “official
    proceeding” but instead relied on Congress’s “purpose” to “protect those
    persons with knowledge of criminal activity who are willing to confide in
    the government” to reach its conclusion. 
    Id. at 1055
    . Second, that court
    never considered that the venue provision could extend to investigations,
    not through the term “official proceeding,” but through the subsequent
    parenthetical phrase—“(whether or not pending or about to be instituted).”
    We thus decline to adopt the Second Circuit’s reading in this case.
    Instead, we find the decision of the Fifth Circuit in Ramos to be far
    more persuasive and relevant for our purposes. See Ramos, 
    537 F.3d at
    460–64. There, unlike Gonzalez, the court directly analyzed the meaning
    of the phrase “official proceeding” as used in the substantive criminal
    provisions of § 1512. Id. Consulting the plain language of the statute and
    the broader context of the statutory scheme, that court determined that
    16                 UNITED STATES V. ERMOIAN
    “before a Federal Government agency” like a hearing or trial
    might; it is conducted “by” the agency in the field.
    Looking more broadly to § 1512 where the term “official
    proceeding” is repeatedly used, it becomes even more
    apparent that a criminal investigation is not incorporated in
    the definition. Section 1512 refers to “prevent[ing] the
    attendance or testimony of any person in an official
    proceeding”; “prevent[ing] the production of a record,
    document, or other object, in an official proceeding”; and
    “be[ing] absent from an official proceeding to which that
    person has been summoned by legal process.” 
    18 U.S.C. § 1512
    (a)(1)(A)–(B), (a)(2)(B)(iv). The use of the terms
    “attendance”, “testimony”, “production”, and “summon[]”
    when describing an official proceeding strongly implies that
    some formal hearing before a tribunal is contemplated.
    Additionally, it would be odd to interpret “official
    proceeding” broadly to incorporate investigations when the
    statutory scheme already provides an explicit mechanism to
    criminalize obstruction of a criminal investigation. Section
    1512(f)(1) states that “an official proceeding need not be
    pending or about to be instituted at the time of the offense”
    for criminal liability to attach under the obstruction of justice
    statute. By extending the statute’s reach to criminal activities
    that occur before “official proceedings” commence, this
    subsection expands the scope of the obstruction of justice
    statute to include criminal investigations. By contrast, if we
    were to read the phrase “official proceeding” to include an
    FBI investigation, as the Government urges us to do, this
    internal agency investigations of employee misconduct were not official
    proceedings. 
    Id.
     Our independent analysis of the text leads us to reach a
    similar conclusion with regard to criminal investigations.
    UNITED STATES V. ERMOIAN                         17
    subsection of the statute would work to criminalize actions
    taken before an investigation was even “pending or about to
    be instituted.” 
    Id.
     We do not think that the obstruction of
    justice statute was intended to reach so far back as to cover
    conduct that occurred even pre-criminal-investigation.
    Indeed, such a construction would be in tension with Supreme
    Court precedent requiring a nexus between the obstructive act
    and criminal proceedings in court. See Arthur Andersen LLP
    v. United States, 
    544 U.S. 696
    , 708 (2005) (interpreting a
    materially similar subsection of § 1512 as requiring that the
    defendant have “knowledge that his actions are likely to
    affect [a] judicial proceeding” in order to have the “requisite
    intent to obstruct”).
    Thus, in light of the plain meaning of the term
    “proceeding,” its use in the grammatical context of the
    “official proceeding” definition, and the boader statutory
    context, we conclude that a criminal investigation is not an
    “official proceeding” under the obstruction of justice statute.6
    B
    The district court in this case instructed the jury that “an
    ‘official proceeding’ includes an investigation by the Federal
    Bureau of Investigation.” As we have already determined,
    such instruction was legally erroneous: an FBI investigation
    is not an official proceeding under the obstruction of justice
    statute.
    6
    Because the meaning of the term “official proceeding” is plain and
    unambiguous, we decline the Government’s invitation to consult the
    statute’s legislative history. See Robinson, 
    519 U.S. at 340
    .
    18                UNITED STATES V. ERMOIAN
    Normally, an error in a jury instruction requires reversal
    of the defendant’s conviction “unless the [error] was harmless
    beyond a reasonable doubt.” United States v. Henderson,
    
    243 F.3d 1168
    , 1171 (9th Cir. 2001). But here, we do not
    need to determine whether the erroneous jury instruction was
    harmless. Both before the district court and on appeal, the
    Government conceded that, if an FBI investigation was not an
    official proceeding, then the obstruction of justice charges
    could not have been sustained on the evidence presented at
    trial.
    The Government’s concession regarding the sufficiency
    of the evidence conclusively resolves this case in the
    defendants’ favor. Not only should their convictions be
    reversed, but retrial must also be barred. United States v.
    Bibbero, 
    749 F.2d 581
    , 586 (9th Cir. 1984) (“An appellate
    reversal of a conviction on the basis of insufficiency of the
    evidence has the same effect as a judgment of acquittal: the
    Double Jeopardy Clause precludes retrial.”). We thus reverse
    and remand to the district court so that it may enter a
    judgment of acquittal on the obstruction of justice charges
    and resentence Johnson.7
    REVERSED and REMANDED.
    7
    Because we reverse the convictions on the basis of the statutory
    interpretation issue, we do not reach any of the defendants’ remaining
    arguments raised on appeal.
