    UNITED STATES OF AMERICA,
    Plaintiff- Appellee,
    versus
    MICHAEL FRANCIS DIFALCO,
    Defendant - Appellant.
    Appeal from the United States District Court
    for the Middle District ofFlorida
    Before MARCUS and WILLIAM PRYOR,Circuit Judges, and LAWSON,
    District Judge.
    MARCUS,Circuit Judge:
    * Honorable Roger H. Lawson, Jr., United States District Judge for the Middle District of
    Georgia, sitting by designation.
    Case: 15-14763     Date Filed: 09/20/2016   Page: 2 of 37
    Michael DiFaIco appeals his 240-inonth sentence imposed after pleading
    guilty to one count ofconspiracy to distribute and possess with intent to distribute
    50 grams or more of methamphetamine. He claims that his sentence was imposed
    in error because the government did not file a proper information under 21 U.S.C.
    § 851 to support his enhanced sentence. But DiPalco signed a plea agreement
    waiving his right to appeal his sentence. Because we hold that a defendant may
    waive § 851's requirements, and the record before us establishes that DiFalco
    knowingly waived his right to appeal his sentence, we dismiss his appeal. But,
    even if we found that the defendant had not knowingly waived his right to
    challenge his sentence in this Court, DiFalco has failed to meet his burden of
    establishing that the district court erred, plainly or otherwise, in imposing a 240-
    month sentence.
    I.
    DiFalco was arrested and charged by a federal grand jury sitting in the
    Middle District ofFlorida for his role acting as the "source" of approximately 81
    grams of methamphetamine for co-defendant Cheyenne Bryant who,in turn,sold
    the drugs on two occasions to a confidential informant working with federal law
    enforcement agents. DiFalco initially pled not guilty to a two-count indictment
    charging both him and Bryant. Bryant subsequently pled guilty to the charges
    leveled against her for conspiracy to distribute and possess with intent to distribute
    Case: 15-14763    Date Filed: 09/20/2016    Page: 3 of 37
    50 grams or more of a substance containing a detectable amount of
    methamphetamine, and possession with intent to distribute and distribution of50
    grams or more of a substance containing a detectable amount of
    methamphetamine. The government then filed a two-count superseding indictment
    charging DiFalco with:(1)conspiracy to distribute and possess with intent to
    distribute 50 grams or more of methamphetamine, in violation of 21 U.S.C.
    §§ 846, 841(a)(1), 841(b)(l)(A)(viii), 851, and 18 U.S.C. § 2; and(2)possession
    with intent to distribute and distribution of50 grams or more of methamphetamine,
    in violation of21 U.S.C. §§ 841(a)(1), 841(b)(l)(A)(viii), 851, and 18 U.S.C. § 2.
    Shortly after the superseding indictment was returned, DiFalco and the
    government began negotiating a possible plea agreement. As court filings from
    both sides indicated, DiFalco faced the possibility of a mandatory life sentence
    based on his multiple prior state-court drug convictions. On June 17, 2013,the
    Assistant United States Attorney responsible for prosecuting DiFalco informed the
    district court that he had received approval from his supervisor to enter into a plea
    agreement whereby the government would file only one 21 U.S.C. § 851
    enhancement against the defendant,thereby reducing his potential sentence
    exposure from a mandatory term of life in prison to a mandatory minimum of20
    years of incarceration.
    Case: 15-14763    Date Filed: 09/20/2016   Page: 4 of 37
    Three days later, DiFalco signed a plea agreement with the United States.
    Pursuant to the terms ofthe deal, DiFalco agreed to plead guilty to Count 1 ofthe
    superseding indictment, and the government agreed to dismiss Count 2 and refrain
    from charging DiFalco with any other federal crimes known to the government and
    related to the conduct giving rise to the agreement. The agreement also provided
    that, by entering a plea of guilty, DiFalco admitted to the charge alleged in Count 1
    and that he had "previously [been] convicted of a felony drug offense." The
    agreement also accurately noted that, by pleading guilty, DiFalco would be
    punished "by a mandatory minimum term of20 years and a maximum term of life
    imprisonment, a term ofsupervised release of at least 10 years, a fine of up to
    $20,000,000, and a special assessment of$100, said special assessment to be due
    on the date of sentencing."
    Notably, the plea agreement also included an appeal waiver that read this
    way:
    The defendant agrees that this Court has jurisdiction and
    authority to impose any sentence up to the statutory
    maximum and expressly waives the right to appeal
    defendant's sentence on any ground, including the
    ground that the Court erred in determining the applicable
    guidelines range pursuant to the United States Sentencing
    Guidelines, except (a) the ground that the sentence
    exceeds the defendant's applicable guidelines range as
    determined bv the Court pursuant to the United States
    Sentencing Guidelines; (b) the ground that the sentence
    exceeds the statutory maximum penalty; or (c) the
    ground that the sentence violates the Eighth Amendment
    Case: 15-14763     Date Filed: 09/20/2016   Page: 5 of 37
    to the Constitution; provided, however, that if the
    government exercises its right to appeal the sentence
    imposed, as authorized by 18 U.S.C. § 3742(b), then the
    defendant is released from his waiver and may appeal the
    sentence as authorized by 18 U.S.C. § 3742(a).
    DiFalco initialed each page ofthe agreement and signed the final page. DiFalco
    acknowledged in the agreement that he was pleading guilty freely and voluntarily.
    On June 27, 2013, before the defendant entered a plea of guilty, the
    government filed an "Information and Notice ofPrior Conviction" pursuant to 21
    U.S.C. §§ 851 and 841(b)(1) notifying DiFalco that he was subject to an enhanced
    mandatory minimum sentence based on a prior felony drug conviction.
    Specifically, the information said that "[o]n or about July 19, 2007,the defendant
    was convicted of sale and possession with the intent to sell Amphetamine and
    Marijuana,in and for the Tenth Circuit Court ofBartow County,Florida, Case
    Number 2000CF8119[.]" The details set forth in the information, however, do not
    precisely align with the conviction contained in DiFalco's record as set forth in his
    Presentence Investigation Report("PSI"). Rather, DiFalco had a prior conviction
    entered on July 19, 2002 for trafficking in amphetamine, manufacture of cannabis,
    possession of MDMA (ecstasy), possession of Alprazolam, use or possession of
    drug paraphernalia, and driving with a suspended license in the Circuit Court in
    Polk County, Florida under case number OO-CF-8119. The PSI noted that DiFalco
    was also charged with possession of cannabis with intent to sell in that case, but
    Case: 15-14763     Date Filed: 09/20/2016   Page: 6 of 37
    that no action was taken on that charge. DiFalco's record, as set forth in the PSI in
    paragraphs 45 and 46, also reveals two other sets ofconvictions on July 19, 2002:
    one for operating a chop shop and grand theft of a motor vehicle under case
    number Ol-CF-676; and another for possession of methamphetamine, possession
    of cannabis, and use or possession of drug paraphernalia under case number 01-
    CF-677. DiFalco also had been convicted of another series of drug and vehicle
    related crimes on October 11, 2010, including possession of methamphetamine
    with intent to sell or deliver; possession ofcannabis with intent to sell; possession
    of Oxycodone; possession of drug paraphernalia; actual or constructive possession
    of a structure used for trafficking, sale, or manufacture ofa controlled substance;
    possession ofa firearm or ammunition by a convicted felon; possession or sale of a
    vehicle with an altered vehicle identification number; and possession of a vessel
    with an altered hull identification number. The PSI did not indicate that DiFalco
    had any convictions for any crimes in 2007. The final page ofthe § 851
    information included a certification that the assistant United States attorney had
    "electronically filed the foregoing with the Clerk ofthe Court by using the
    CM/ECF system which will send a notice of electronic filing to the counsel of
    record."
    Later that day, DiFalco appeared at a change-of-plea hearing before a
    magistrate judge to enter a plea of guilty to the federal drug conspiracy count. The
    Case: 15-14763   Date Filed: 09/20/2016   Page: 7 of 37
    magistrate judge first ascertained that DiFalco was not under the influence of any
    type of drug or alcoholic beverage. The magistrate judge then explained the terms
    ofthe plea agreement to DiFalco in order to ensure that he understood the terms of
    the agreement. Among other things, the magistrate judge explained that the plea
    agreement provided that DiFalco would plead guilty to the first count ofthe
    indictment, that the government would dismiss the remaining counts against him,
    that the government would recommend he receive a sentence within the Guidelines
    range,that the government would recommend a downward adjustment in that
    range based on his acceptance of responsibility, that DiFalco agreed to cooperate
    hilly with the government in its investigation and prosecution of others, and that
    DiFalco would forfeit any and all assets subject to forfeiture as a consequence of
    his illegal activity.
    The magistrate judge also reviewed with DiFalco the penalties he would face
    upon pleading guilty to the conspiracy charge. Thus, he explicitly told DiFalco
    that he faced a minimum mandatory penalty of20 years in prison and up to a
    maximum sentence of life imprisonment, a term ofsupervised release of at least 10
    years, a fine of up to $20 million, and a special assessment in the amount of$100.
    The magistrate judge explained to DiFalco that the government had filed a notice
    ofinformation and so DiFalco potentially faced an enhanced prison term because
    Case: 15-14763    Date Filed: 09/20/2016    Page: 8 of 37
    of one of his prior drug convictions. DiFalco said that he understood these
    penalties.
    The magistrate judge also explained the appeals waiver found in the plea
    agreement,telling DiFalco what the waiver meant and what exceptions applied.
    Specifically, the defendant was told that although he would ordinarily have the
    right to appeal his sentence to the Eleventh Circuit Court of Appeals, he was
    waiving his right to do so unless his sentence exceeded the applicable Guideline
    range, his sentence exceeded the statutory maximum penalty, or the sentence
    violated the Eighth Amendment prohibition against cruel and unusual punishment.
    Once again, DiFalco said that he understood.
    The judge then explained the many trial rights that DiFalco would surrender
    by entering a plea of guilty. Among them were included the right to ajury trial at
    which the government would have to prove its case beyond a reasonable doubt,the
    right to be represented by counsel, the right to cross-examine witnesses against
    him,the right to testify or not testify as he wished, and the right to invoke
    subpoena power to compel witnesses to testify on his behalf. DiFalco said that he
    understood this too. Finally, after the magistrate judge explained the elements of
    the charge ~ including that DiFalco had conspired to distribute and possess with
    intent to distribute 50 or more grams of methamphetamine and that he had a prior
    conviction for a felony drug offense subjecting him to a minimum mandatory
    Case: 15-14763     Date Filed: 09/20/2016    Page: 9 of 37
    enhancement- DiFalco pled guilty. DiFalco's counsel said that he was satisfied
    his client was pleading guilty knowingly and voluntarily and with a full
    understanding ofthe consequences. Finding that the plea had been entered both
    knowingly and voluntarily, the magistrate judge recommended that it be accepted
    by the district court. The district court did so on July 15, 2013.
    The district court conducted a sentencing hearing on September 16, 2013. It
    overruled DiFalco's objections that some of his prior convictions that the PSI
    treated as separate offenses ought to be classified as one offense for purposes of
    calculating DiFalco's criminal history category. The district court calculated that
    DiFalco had an offense level of34 and a criminal history category of VI, yielding a
    Guidelines range of262 to 327 months. DiFalco's attorney argued that the district
    court should enter a downward variance based on DiFalco's abused childhood and
    the fact that he had turned to drugs as a coping mechanism for dealing with a series
    of serious injuries. Twice during the course of his argument,the defendant's
    counsel acknowledged that DiFalco faced a mandatory minimum term of20 years'
    imprisonment. Indeed, DiFalco himself also noted that fact during his own
    remarks to the court, saying,"My crime carries ten years, but my past of being a
    drug addict doubles it to 20." The defendant also acknowledged having seen the
    PSI and discussing it with counsel.
    Case: 15-14763     Date Filed: 09/20/2016    Page: 10 of 37
    The district court did vary downward from the guidelines range, sentencing
    DiFalco to the mandatory minimum of240 months' imprisonment followed by 10
    years ofsupervised release. The district court waived imposition ofa fine, but
    levied a special assessment of$100. Notably, defense counsel offered no objection
    to the sentence or the manner of its announcement when asked by the district court
    at the conclusion ofthe proceeding.
    No appeal was filed within the time period permitted under Fed. R. App.P.
    4(b)(1). But, in 2014,the district court granted DiFalco's 28 U.S.C. § 2255
    application claiming that he had received ineffective assistance of counsel because
    his lawyer failed to file a notice of appeal despite having been directed to do so.
    The district court vacated the judgment so that the sentence could be re-imposed,
    thereby allowing DiFalco to file a timely notice of appeal to this Court. On
    October 23,2015,the district court re-imposed the same sentence on DiFalco.
    This timely appeal followed.
    11.
    DiFalco argues broadly that the government has failed to comply with
    § 851(a)(l)'s notice requirements, rendering his enhanced sentence invalid. He
    asks this Court not to "vacate his entire guilty plea or plea agreement, but only his
    agreement to an enhanced minimum penalty." Moreover, DiFalco says that the
    district court failed to ensure during the plea colloquy that he understood he was
    10
    Case: 15-14763    Date Filed: 09/20/2016    Page: 11 of 37
    pleading to an enhanced minimum sentence; and that it also erred by failing to
    comply with § 85l(b)'s requirement that he be given the opportunity to affirm or
    deny the particular prior conviction that was used to enhance his sentence.
    A.
    DiFalco pled guilty to conspiring to distribute and possess with intent to
    distribute 50 grams or more of methamphetamine in violation of21 U.S.C.
    §§ 841(a)(1), 841(b)(l)(A)(viii), 846, and 851. Section 841 makes it a crime "to
    manufacture, distribute, or dispense, or possess with intent to manufacture,
    distribute, or dispense, a controlled substance." 21 U.S.C. § 841(a)(1). Where the
    controlled substance involves 50 grams or more of methamphetamine -- as was the
    case here - the defendant faces a prison sentence ranging from a mandatory
    minimum of 10 years to a maximum of life, followed by a five-year term of
    supervised release. 21 U.S.C. § 841(b)(l)(A)(viii). If, however,the defendant had
    previously been convicted of a felony drug offense, the mandatory minimum term
    ofimprisonment rises to 20 years, followed by a 10-year term of supervised
    release. Id The maximum term ofimprisonment remains life. Id Section 846
    makes it a crime to attempt or conspire to commit any ofthe crimes defined in that
    subchapter ofthe United States Code. 21 U.S.C. § 846.
    Although § 841 provides for enhanced sentences for defendants previously
    convicted offelony drug offenses, these enhancements are not automatic. Rather,
    11
    Case: 15-14763     Date Filed: 09/20/2016    Page: 12 of 37
    the government is required by the terms of§ 851 first to file an information
    providing notice ofthe previous conviction supporting the enhanced sentence.
    Thus,§ 851 provides:
    No person who stands convicted of an offense under this
    part shall be sentenced to increased punishment by
    reason of one or more prior convictions, unless before
    trial, or before entry of a plea of guilty, the United States
    attorney files an information with the court(and serves a
    copy of such information on the person or counsel for the
    person) stating in writing the previous convictions to be
    relied upon.
    21 U.S.C. § 851(a)(1). This notice allows the defendant to contest the accuracy of
    the government's pleading as well as affording the defendant "ample time to
    determine whether to enter a plea or go to trial and plan his trial strategy with full
    knowledge ofthe consequences ofa potential guilty verdict." United States v.
    Ramirez. 
    501 F.3d 1237
    , 1239(11th Cir. 2007)(quoting United States v. Williams,
    59F.3d 1180, 1185 (11th Cir. 19951k accord United States v. DuffV. 179F.3d
    1304, 1305 (11th Cir. 1999). These procedural safeguards are mandatory and must
    be followed in all cases before a defendant's sentence may be enhanced under
    § 841. Carachuri-Rosendo v. Holder. 560 U.S. 563,569 & n.6(2010); United
    States V. Thompson.473 F.3d 1137, 1144(11th Cir. 2006).
    The statute also provides that after the § 851 information has been filed, the
    district court shall inquire ofthe defendant whether he affirms or denies the
    conviction alleged in the information and "inform him that any challenge to a prior
    12
    Case: 15-14763     Date Filed: 09/20/2016   Page: 13 of 37
    conviction which is not made before sentence is imposed may not thereafter be
    raised to attack the sentence." 21 U.S.C. § 851(b). A defendant who challenges
    the convictions alleged in the information must file a written response to the
    information, at which point the district court shall hold a hearing. 21 U.S.C.
    § 851(c)(1). But"[n]o person who stands convicted of an offense under this part
    may challenge the validity ofany prior conviction alleged under this section which
    occurred more than five years before the date ofthe information alleging such prior
    conviction." 21 U.S.C. § 851(e).
    B.
    Before we turn to the merits of DiFalco's § 851 claims, we are obliged first
    to address the government's argument that DiFalco waived his right to appeal this
    issue in his plea agreement. Ifthat waiver applies, DiFalco would be barred from
    raising his claim and we would be required to dismiss his appeal. United States v.
    Johnson, 
    541 F.3d 1064
    , 1069(11th Cir. 2008); United States v. Howie, 
    166 F.3d 1166
    , 1168(11th Cir. 1999).
    "We review the validity of a sentence appeal waiver de novo." 
    Johnson, 541 F.3d at 1066
    ; United States v. Bushert,997 F.2d 1343, 1352(11th Cir. 1993). In
    order to be valid, the appeal waiver must be made knowingly and voluntarily.
    Bushert,997 F.2d at 1350. To enforce an appeal waiver, the government must
    establish either that "(1)the district court specifically questioned the defendant
    13
    Case: 15-14763     Date Filed: 09/20/2016    Page: 14 of 37
    concerning the sentence appeal waiver during the Rule 11 colloquy, or(2)it is
    manifestly clear from the record that the defendant otherwise understood the full
    significance ofthe waiver." Id, at 1351; accord 
    Johnson, 541 F.3d at 1066
    .
    Significantly, a waiver of appellate rights applies not only to frivolous claims, but
    also to difficult and debatable legal issues. 
    Johnson, 541 F.3d at 1068
    ; United
    States V. Grinard-Henrv, 
    399 F.3d 1294
    , 1296(11th Cir. 2005); 
    Howie, 166 F.3d at 1169
    . Indeed, it even "includes a waiver ofthe right to appeal blatant error."
    
    Howie, 166 F.3d at 1169
    : accord 
    Johnson, 541 F.3d at 1068
    ; 
    Grinard-Henrv, 399 F.3d at 1296
    . Thus,even issues that are vigorously disputed at sentencing are not
    exempted from an otherwise valid and applicable appeal waiver. United States v.
    Bascomb,451 F.3d 1292, 1296(11th Cir. 2006); United States v. Buchanan, 
    131 F.3d 1005
    , 1007, 1009(11th Cir. 1997).
    That said, the parties may not waive a jurisdictional defect. McCov v.
    United States, 
    266 F.3d 1245
    , 1249(11th Cir. 2001). Because the federal courts
    are courts oflimited jurisdiction, deriving their power from Article III ofthe
    Constitution and from the legislative acts of Congress,the parties cannot confer
    upon the courts a jurisdictional foundation that they otherwise lack. Harris v.
    United States, 149 F.3d 1304,1308(11th Cir. 1998). Thus, a party's waiver or
    procedural default would be insufficient to confer subject-matter jurisdiction.

    Harris, 149 F.3d at 1308
    . A judgment tainted by a
    14
    Case: 15-14763     Date Filed: 09/20/2016   Page: 15 of 37
    jurisdictional defect- even one that has been waived ~ must be reversed. 
    McCoy, 266 F.3d at 1249
    .
    1.
    The first question before us, then, boils down to whether § 851 is in fact a
    jurisdictional requirement. This Court and its predecessor Court, the former Fifth
    Circuit Court of Appeals, have repeatedly held that it is. Thus,for example, in
    Harris v. United States, we relied on this Court's repeated and binding precedent in
    concluding that a district court lacked jurisdiction to impose an enhanced § 851
    sentence absent the government filing an information in accordance with the
    requirements ofthe 
    statute. 149 F.3d at 1306-07
    (citing United States v. Olson,
    
    716 F.2d 850
    , 853(11th Cir. 1983); United States v. Cevallos, 
    538 F.2d 1122
    ,
    1125 n.4(5th Cir. 1976); United States v. Noland,495 F.2d 529, 533(5th Cir.
    1974)). These precedents led us to conclude that"even where a defendant receives
    actual notice that the government intends to rely on a previous conviction to
    enhance his sentence, the district court lacks jurisdiction to impose an enhanced
    sentence until the government files an information as required under § 851." 
    Id. at 1307.
    We held, therefore, that a § 2255 applicant was not required to show cause
    or prejudice to obviate a procedural default by failing to object to the § 851
    information at trial because a jurisdictional defect could not be procedurally
    defaulted or waived. 
    Id. at 1308-09;
    see also United States v. Jackson, 
    544 F.3d 15

    Ramirez. 501 F.3d at 1239-40
    ; Thompson.473
    F.3d at 1144. We have since cast doubt on whether Harris's jurisdictional holding
    remains good law in light ofsubsequent Supreme Court rulings. United States v.
    Ladson.643 F.3d 1335, 1343 n.ll (11th Cir. 20111 Iciting Eberhart v. United
    States. 546 U.S. 12,16(2005); Kontrick v. Ryan. 540 U.S. 443,455 (2004)).
    We are required to adhere to our past decisions. United States v. Archer.
    
    531 F.3d 1347
    , 1352(11th Cir. 20081: United States v. Steele. 
    147 F.3d 1316
    ,
    1317-18(11th Cir. 1998)(en banc). But the rule is not without exception. Thus,
    we are not bound by the decisions ofour prior panels where those decisions have
    been overruled or undermined to the point of abrogation by the Supreme Court or

    "actually abrogate or directly conflict with, as opposed to merely weaken,the
    holding ofthe prior panel." United States v. Kalev. 579 F.3d 1246,1255(11th Cir.
    2009).
    We hold today that our decisions that § 851 imposes ajurisdictional limit on
    a district court's authority have been undermined to the point of abrogation by
    subsequent decisions ofthe Supreme Court. First, in Kontrick v. Rvan.540 U.S.
    443(2004),the Supreme Court considered Federal Rule of Bankruptcy Procedure
    16
    Case: 15-14763     Date Filed: 09/20/2016   Page: 17 of 37
    4004's strict time limits on when a creditor may file an objection to a debtor's
    discharge from bankruptcy. In that case, a creditor filed an untimely objection to a
    debtor's discharge, but the debtor did not argue the untimeliness ofthe objection
    until after the bankruptcy court had decided the issue on the merits. 
    Id. at 446.
    If
    the rule's requirements were jurisdictional, the debtor's delay in challenging the
    objection would not matter because a jurisdictional defect may be raised at any
    time in a civil action. 
    Id. at 455.
    The Court concluded that, although the time limit
    prescribed by the rule could not be altered by the parties' application, it was
    nonetheless not a jurisdictional requirement because it did not "delineate what
    cases bankruptcy courts are competent to adjudicate." Ift at 454. Indeed,the
    bankruptcy courts'jurisdiction over objections to discharge had been statutorily
    granted by Congress in 28 U.S.C. § 157. Id,at 453. Most significantly for our
    purposes, the Supreme Court instructed us thatjurisdictional rules are reserved
    "only for prescriptions delineating the classes ofcases(subject-matterjurisdiction)
    and the persons(personal jurisdiction)falling within a court's adjudicatory
    authority." Id,at 455. Thus, because Rule 4004 did not define the class ofcases or
    persons subject to the bankruptcy courts' adjudicatory authority, it served as a
    claim-processing rule rather than ajurisdictionally imposed requirement. Id The
    significance ofthis distinction was that, unlike ajurisdictional rule, a claim-
    processing rule can be forfeited by a party. 
    Id. at 456.
    Because Rule 4004 did not
    17
    Case: 15-14763       Date Filed: 09/20/2016      Page: 18 of 37
    fall within the Supreme Court's newly clarified conception ofjurisdictional
    provisions, the debtor was not permitted to invoke it after he had litigated and lost
    the case on the merits, as he would have been permitted to do had the rule been
    jurisdictional. 
    Id. at 460.
    The Supreme Court noted that its use ofthe term
    "jurisdictional" in the past had been "less than meticulous," but indicated a firm
    commitment to clarifying its use in the future. 1^ at 454.
    The Supreme Court was given an opportunity to do so again the following
    year when it decided Eberhart v. United States, 546 U.S. 12(2005). There,the
    Court had to determine whether a defendant's failure to comply with Fed. R. Crim.
    P. 33(b)(2)'s rigid seven-day deadline for moving for a new trial could be raised by
    the government after the district court had ruled on the merits ofthe motion.^ Id at
    13. Applying the same rationale it had used in Kontrick,the Supreme Court
    highlighted the "critical difference between a rule governing subject-matter
    jurisdiction and an inflexible claim-processing rule." Id.(quoting Kontrick,540
    U.S. at 456). It reiterated that the label "jurisdictional" should be reserved only for
    those issues that delineated a court's adjudicatory authority. Id at 16. Because
    Rule 33 did not speak to the district court's authority over the subject-matter ofthe
    case, nor did it limit the power ofthe district court to adjudicate the case, it was not
    a jurisdictional rule immune to forfeiture. Id at 16, 19. This was so, even though
    The deadline has since been extended to 14 days. Fed. R. Crim. P. 33(b)(2).
    18
    Case: 15-14763     Date Filed: 09/20/2016   Page: 19 of 37
    Rule 33's timeliness requirement remained both unmistakable and mandatory. Id
    at 16-17. Thus,the Court held that Rule 33 is a claim-processing rule that,
    although mandatory, could be forfeited when, as in that case, it had not been timely
    raised. 
    Id. at 19.
    This more-focused conception ofjurisdiction was anticipated by our Court
    in its en banc decision in United States v. Sanchez, 269 F.3d 1250(11th Cir. 2001)
    (en banc), abrogated on other grounds by United States v. Duncan,400 F.3d 1297,
    1308(11th Cir. 2005). In Sanchez, we rejected the defendants' claims that an
    Apprendi error is structural or jurisdictional in the course of concluding that
    harmless error review applies. Id at 1272-75. We wrote that"[a]jurisdictional
    defect occurs only where a federal court lacks power to adjudicate at all." Id at
    1273(emphasis added). Significantly, this is wholly consonant with the Supreme
    Court's admonition in Kontrick that the label "jurisdictional" should be reserved
    only for those prescriptions delineating the court's adjudicatory authority over
    classes of cases and persons. See 
    Kontrick, 540 U.S. at 455
    . It should not be
    applied to prescriptions(or proscriptions) limiting a court's actions in a case in
    which the court's underlying authority to decide the matter is unquestioned.
    Most recently, in Santiago-Lugo v. Warden,785 F.3d 467,471 (11th Cir.
    2015), we determined that the Supreme Court had abrogated our prior case law
    holding that a habeas petitioner's failure to exhaust all available administrative
    19
    Case: 15-14763     Date Filed: 09/20/2016    Page: 20 of 37
    remedies created a jurisdictional defect. We noted that the "term 'jurisdiction' has
    become 'a word of many,too many, meanings,'"id. at 472(quoting Steel Co. v.
    ritiVftns for a Better Env't. 523 U.S. 83,90(1998)), and does not apply to "claim-
    processing rules" that"seek to promote the orderly progress of litigation by
    requiring that the parties take certain procedural steps at certain specified times,"
    id.(quoting Henderson ex rel. Henderson v. Shinseki. 562 U.S. 428,435 (2011)).
    In short, we said,"where Congress does not say there is a jurisdictional bar,there
    is none." Id at 473(citing Reed Elsevier. Inc. v. Muchnick.559 U.S. 154,161-62
    (2010)).
    It is clear that the Supreme Court's holdings in Kontrick and Eberhart and
    their rationale have undermined to the point of abrogation our prior holdings that
    the requirements found in § 851 are jurisdictional in nature. There is no way to
    reconcile our holding in Harris and the other decisions we have cited with the
    understanding of what makes a statute "jurisdictional" announced by the Supreme
    Court. For starters, it is clear that § 851's notice requirement does not affect the
    district court's subject-matter jurisdiction over cases involving offenses against the
    laws ofthe United States. To the contrary, that authority is plainly vested in the
    district courts by Congress. Thus,in 18 U.S.C. § 3231 Congress legislated:"The
    district courts ofthe United States shall have original jurisdiction, exclusive ofthe
    courts ofthe States, of all offenses against the laws ofthe United States."
    20
    Case: 15-14763      Date Filed: 09/20/2016    Page: 21 of 37
    Moreover,this jurisdictional grant necessarily includes the requirement to sentence
    pursuant to the penalties as codified by Congress. Any deficiency found in a § 851
    notice cannot and does not mean that the district court lacks the power to
    adjudicate the case at all. Cf Sanchez.269 F.3d at 1273. Rather,§ 851 provides
    a procedural step that may be required before a statutorily enhanced sentence may
    be imposed. The failure to abide by that mandated procedural step does not mean
    that the court is left without the power to act at all - it simply means that the court
    may be erroneously exercising its power if it wrongly applies a § 851
    enhancement. The erroneous exercise of a § 851 enhancement is plainly subject to
    correction on review by the appellate courts without resorting to the obviously
    erroneous suggestion that the district court lacked all authority to decide the
    criminal case or to impose a sentence in the first instance. The essential point is
    that a court's jurisdiction, or power to adjudicate a case, derives from the court s
    statutory or constitutional authority. Section 851 is essentially a claim-processing
    rule that has no impact on the district court's subject-matter jurisdiction.
    That § 851 is denuded ofany jurisdictional component is evidenced by the
    fact that the district court had the lawful power to accept DiFalco's plea and
    impose a sentence upon him. And,indeed, it had the statutory authority to impose
    the very same 240-month sentence even without the filing ofany § 851
    21
    Case: 15-14763     Date Filed: 09/20/2016    Page: 22 of 37
    information. The enhancements made possible by § 851 only limited the district
    court's ability to impose a sentence lower than the one it imposed on DiFalco.
    In holding that our prior opinions on this point have been undermined to the
    point of abrogation, we join at least one of our sister circuits in concluding that the
    Supreme Court rulings require that we disregard previous decisions declaring the
    requirements found in § 851 to be jurisdictional. See United States v. Flowers,464
    F.3d 1127,1130(10th Cir. 2006)("We now expressly overrule our previous
    decisions that have improperly designated § 851(a)'s requirements as
    jurisdictional."). In holding that § 851 is not a jurisdictional requirement, we join
    the unanimous opinion of nine other circuit courts of appeals to have ruled on the
    subject, both before and after the Supreme Court's recent explication ofthe
    difference between a jurisdictional requirement and a claim-processing rule. S^
    United States v. Pritchett. 
    496 F.3d 537
    , 546(6th Cir. 2007)("This Circuit now
    joins the majority ofits sister circuits in holding that the section 851(a)
    requirements are notjurisdictional.")^ United States v. Beasley, 
    495 F.3d 142
    , 146

    therefore is subject to the usual rules of procedural default."); Flowers,464 F.3d at
    1129("Section 851(a)and its requirements fall neatly within the category of a

    § 851(a)'s procedural requirements are notjurisdictional, and our prior cases
    holding otherwise are expressly overruled on that issue."); United States v.
    Dodson,288 F.3d 153, 160 & n.9(5th Cir. 2002)("Considering the right protected
    by § 851, we see no reason why the rights afforded under that statute may not be
    waived."); United States v. Mooring,287 F.3d 725,727(8th Cir. 2002)("Having
    considered the case law on each side, we conclude the prosecution's
    noncompliance with § 851(a)(1) does not affect the court's jurisdiction."); Prou v.
    United States. 199 F.3d 37,46(1st Cir. 1999)("Accordingly, we hold that
    noncompliance with the procedural regime established by section 851(a)(1)
    deprives the sentencing court of authority to impose an enhanced sentence ~ no
    more and no less."); United States v. Vanness, 85 F.3d 661,663 n.2(D.C. Cir.
    1996)("'Jurisdiction' is a word of many,too many, meanings. We prefer to put
    the matter in different terms. A prosecutor's compliance with § 851(a)(1)is simply
    a necessary condition to a judge's imposing an enhanced sentence on the basis ofa
    defendant's prior convictions."); but see United States v. Severino, 
    316 F.3d 939
    ,
    953 n.4(9th Cir. 2003)(declining to consider whether § 851's requirements were
    jurisdictional because, in either event, reversal was required).
    Lest there be any confusion, our holding today that § 851 is not a
    jurisdictional provision does not in any way affect our holdings that § 851 imposes
    23
    Case: 15-14763    Date Filed: 09/20/2016   Page: 24 of 37
    mandatory requirements on the government before a court may enhance a sentence
    under § 841. See Ladson,643 F.3d at 1343-44("Today, we hold that the statutory
    language of§ 851(a)(1)requires the Government to strictly comply with the
    service requirement before trial."); Thompson.473 F.3d at 1144("The
    requirements of§ 851 are not precatory; they must be followed in order for the
    § 841 enhancements to be applied.").
    2.
    Having concluded that § 85rs requirements are notjurisdictional - and,
    thus, subject to waiver ~ we turn to whether DiFalco did knowingly and
    voluntarily waive his right to challenge the § 851 notice when he signed the plea
    agreement. Upon a fair review ofthis record, we are satisfied that DiFalco
    knowingly and voluntarily waived his right to appeal his sentence. Thus, we
    dismiss his appeal. There is no dispute - and it is abundantly clear in the record -
    that the magistrate judge specifically engaged in an extensive colloquy with
    DiFalco about the nature and function ofthe sentence appeal waiver found in his
    plea agreement during the Rule 11 colloquy. The magistrate judge explained that
    DiFalco would ordinarily have the right to appeal his sentence, but that if he
    entered a plea of guilty he would be waiving his right to appeal unless one ofthe
    three exceptions outlined in the agreement had been met. DiFalco said he
    understood that he was giving up his right to appeal his sentence unless one of
    24
    Case: 15-14763    Date Filed: 09/20/2016   Page: 25 of 37
    those exceptions was met. None ofthose exceptions are applicable here and we
    have little difficulty concluding that DiFalco entered into this appeal waiver
    knowingly and voluntarily. See 
    Bushert, 997 F.2d at 1351
    ; 
    Johnson, 541 F.3d at 1066
    .
    To the extent that DiFalco claims that his plea was not entered knowingly
    and voluntarily because the magistrate judge never clarified that his prior felony
    drug conviction qualified him for an enhanced minimum sentence, we remain
    unpersuaded. This argument is unsupported by the record. In the course of
    explaining the elements ofthe crime that the government would have to prove
    should DiFalco wish to exercise his right to go to trial, the magistrate judge
    explained "out ofan abundance of caution" that"the government would be
    required to prove that you have a prior conviction for a felony drug offense
    subjecting you to the minimum mandatory enhancement." DiFalco said that he
    understood this.
    The long and short of it is, the § 851 errors that DiFalco highlights were
    properly waivable and were knowingly and voluntarily waived by him.
    III.
    Moreover, and as an independent basis for our ruling, we hold that even if
    the defendant did not knowingly waive his right to challenge his enhanced
    sentence, his claim fails on the merits. DiFalco cites to four errors in the § 851
    25
    Case: 15-14763        Date Filed: 09/20/2016       Page: 26 of 37
    proceeding:(1)the inaccuracies in the government's § 851 notice rendered it
    insufficient;(2)the government did not timely file the notice;(3)the magistrate
    judge failed to conduct an appropriate Rule 11 colloquy; and(4)the district court
    erred by not making a § 851(b)inquiry. None ofthese claims were raised in the
    district court. Therefore, we may review them only for plain error. United States
    V. Williams,469 F.3d 963,965 (11th Cir. 2006).
    We may correct a plain error only when(1)an error has occurred,(2)the
    error was plain, and(3)the error affected substantial rights. See United States v.
    Williams, 
    527 F.3d 1235
    , 1240(11th Cir. 2008). An error is plain where it is
    "clear" or "obvious." United States v. Qlano,507 U.S. 725, 734(1993). "Under
    plain-error review, the silent defendant has the burden 'to show the error plain,
    prejudicial, and disreputable to the judicial system.' United States v. Monroe,
    
    353 F.3d 1346
    , 1349-50(11th Cir. 2003)(quoting United States v. Vonn,535 U.S.
    55,65 (2002)); United States v. Rodriguez,398 F.3d 1291, 1299(11th Cir. 2005).
    ^ DiFalco argues that plain error review does not apply to a challenge to the sufficiency of
    § 851 notice and that de novo review applies to such a challenge. But the cases DiFalco cites in
    support ofthe application ofde novo review are cases in which the issue had been
    contemporaneously raised before the trial court. See Ladson,643 F.3d at 1340( Ladson s
    sentencing counsel objected to the sentence enhancement, arguing that the second information
    was not properly filed and served in accordance with § 
    85l(a)(l).")'»Jackson, 544 F.3d at 1180
    ("In his objections to the PSI, Jackson argued, inter alia, the four prior convictions listed in the
    § 851 notice were invalid and moved to dismiss the § 851 notice."); 
    Ramirez, 501 F.3d at 1238
    -
    39(applying de novo review on the government's appeal ofthe district court's decision that
    § 851 notice had not been timely filed under the appropriate case number). The purpose behind
    imposing the requirements of plain error review is to enforce the requirement that these kinds of
    objections should first be made in district court so that the trial court may address and resolve
    them contemporaneously.
    26

    "If all three conditions are met, an appellate court may then exercise its discretion
    to notice a forfeited error, but only if(4)the error seriously affect[ed] the fairness,
    integrity, or public reputation ofjudicial proceedings." United States v. Cotton,
    535 U.S. 625,631-32(2002)^quoting Johnson v. United States, 520 U.S. 461,467
    (1997)). The plain error test is "difficult to meet" and places "a daunting obstacle
    before the appellant." 
    Rodriguez. 398 F.3d at 1298
    (alteration adopted)(quoting
    United States v. King. 
    73 F.3d 1564
    , 1572(11th Cir. 1996)); United States v.
    Pielago. 135 F.3d 703,708(11th Cir. 1998)). Thus,"[t]he Supreme Court has
    instructed us that plain error review should be exercised 'sparingly,' and only 'in
    those circumstances in which a miscarriage ofjustice would otherwise result.'"
    Id,(citation omitted)(quoting Jones v. United States. 527 U.S. 373,389(1999);
    
    Qlano. 507 U.S. at 736
    ). DiFalco has failed to meet his burden to establish error,
    let alone error that was plain or obvious, that affected his substantial rights, or the
    fairness and integrity ofthe judicial proceedings.
    A.
    First, DiFalco objects to the sufficiency ofthe § 851 information, arguing
    that it was rife with inaccuracies. While the § 851 notice was hardly a model to be
    emulated by prosecutors in future cases,the notice was sufficient to satisfy the
    mandatory requirements ofthe statute. See Ladspn,643 F.3d at 1343-44, United
    States V. Rutherford, 175 F.3d 899,904(11th Cir. 1999). Notice under § 851 is
    27
    Case: 15-14763     Date Filed: 09/20/2016   Page: 28 of 37
    required even where "the defendant is not surprised by the enhanced sentence, was
    aware from the outset that his previous conviction could lead to an enhanced
    sentence, never challenged the validity ofthe prior conviction, and admitted it at
    the sentencing hearing." United States v. Weaver,905 F.2d 1466,1481 (11th Cir.
    1990). Indeed, we have written that "[s]trict compliance would seem to be an easy
    thing for the government to do." 
    Rutherford, 175 F.3d at 904
    . That said, strict
    compliance does not require perfection in the notice. Perez v. United States, 
    249 F.3d 1261
    , 1267(11th Cir. 2001). Thus, in Perez, we found that sufficient § 851
    notice had been provided even though the information timely filed by the
    government listed the incorrect year ofthe defendant's prior conviction. Id at
    1263, 1267. We adopted the reasoning from our sister circuits that"an information
    complies with the requirements of§ 851(a)(1)even if it contains an error in its
    contents, provided that the information serves to signal unambiguously the
    government's intent to seek an enhancement based on a particular prior
    conviction." 
    Id. at 1265.
    Here,the § 851 information provided sufficient notice ofthe government's
    intent to seek an enhancement based on a particular and defined prior felony drug
    conviction. The notice stated that on or about July 19, 2007,the defendant was
    convicted ofsale and possession with the intent to sell amphetamine and
    marijuana, in and for the Tenth Circuit Court ofBartow County,Florida, under
    28
    Case: 15-14763     Date Filed: 09/20/2016    Page: 29 of 37
    case number 2000CF8119. In fact, DiFalco was convicted on July 19,2002 for
    trafficking in amphetamine under case number OO-CF-8119, in the Circuit Court of
    Polk County, Florida. It is not at all clear that the district court's acceptance ofthe
    notice was error at all, let alone one that was plain or obvious.
    First, significantly, the information correctly listed the underlying case
    number. That the case number in the information listed the full year ofthe arrest
    (2000)instead of simply the last two digits ofthe year(00)did not make the listing
    incorrect, let alone did it introduce any ambiguity as to which conviction the
    government was relying upon. In the second place, we are hard pressed to see how
    listing the court of conviction as the "Tenth Circuit Court ofBartow County,
    Florida" would confuse DiFalco about the venue of his conviction which was in
    Florida's Tenth Judicial Circuit, the circuit that encompasses Polk County and the
    city ofBartow. Moreover, as we held in Perez, an incorrect last digit in the year of
    the prior conviction is not enough to make the § 851 notice insufficient.          
    id. at 1263.
    A scrivener's error does not warrant the vacatur of a sentence where the
    evidence overwhelming establishes that the defendant plainly knew what prior
    crime formed the foundation ofthe § 851 notice. This is particularly so where
    DiFalco had no convictions in 2007 for any crime that might have led him astray.
    Finally, the difference between DiFalco's listed conviction for sale and
    possession with the intent to sell amphetamine and marijuana and his actual
    29
    Case: 15-14763    Date Filed: 09/20/2016       Page: 30 of 37
    conviction for trafficking in amphetamine is minimal. This is particularly so where
    Florida's trafficking in amphetamine statute at the time of DiPalco's conviction
    read this way:
    Any    person      who   knowingly      sells,     purchases,
    manufactures, delivers, or brings into this state, or who is
    knowingly in actual or constructive possession of, 14
    grams or more of amphetamine ... commits a felony of
    the first degree, which felony shall be known as
    "trafficking in amphetamine"....
    Fla. Stat. Ann.§ 893.135(l)(f)(l)(2002). That the information listed the
    conviction's elements rather than formal title oftrafficking appears to us to be
    exceedingly unlikely to have caused DiFalco any confusion. This is especially true
    where DiFalco's criminal record reveals only one conviction regarding
    amphetamines(as opposed to methamphetamines). The erroneous listing ofa
    marijuana conviction in the information(when,in fact, no action was taken on that
    charge)is ofno moment because, in emy event, DiFalco had plainly and undeniably
    been put on notice that the government was relying on his amphetamine
    conviction. Any marginal puzzlement DiFalco may have experienced would have
    been more than overcome by the bulk ofthe information accurately describing his
    conviction.
    As we see it, DiFalco had enough accurate information to enable him easily
    to research, identify, and potentially contest the accuracy ofthe notice and
    information. Had he been confused as to which conviction the government relied
    30
    Case: 15-14763     Date Filed: 09/20/2016   Page: 31 of 37
    upon in seeking an enhanced sentence, he had many opportunities to make that
    confusion known both at his change of plea hearing and at his sentencing. But he
    failed to contest the information in any way until this appeal. Thus, while the
    information was sloppily prepared by the government in this case, we do not
    believe that DiFalco has met his burden ofshowing an error, let alone an error that
    was plain or obvious.
    But even ifthe error in the notice was plain or obvious, DiFalco has not
    carried his burden ofshowing that the error affected his substantial rights. At the
    outset, we note that DiFalco's Guidelines range, independent ofany § 851
    enhancement, was 262 to 327 months' imprisonment based on his offense and
    criminal history, none of which had been challenged by the defendant. Thus,even
    without considering the enhancement, DiFalco faced a recommended prison
    sentence longer than the one he actually received. To be sure, the district court
    varied downward when it sentenced DiFalco to the mandatory 20 year minimum
    term. But this does not require that we conclude that DiFalco has carried his
    burden ofshowing that the district court likely would have departed dovraward still
    further but for the application ofthe enhanced mandatory minimum. This is
    particularly so where DiFalco can point to nothing in the record where the district
    court lamented his inability to impose a lower sentence. To the contrary, the
    district court noted that there were "a lot ofreasons" that DiFalco should be
    31
    Case: 15-14763     Date Filed: 09/20/2016    Page: 32 of 37
    sentenced in the middle or even at the high end ofthe Guidelines range before
    concluding that he was "confident that the sentence is sufficient, but not greater
    than necessary to comply with the statutory purposes of sentencing." In fact, the
    district court went out of its way to make sure DiFalco understood how close he
    had come to serving a life sentence.
    Finally, DiFalco has fallen far short of establishing that any alleged error
    seriously affected the fairness, integrity, or public reputation ofthe judicial
    proceedings in his case. He simply cannot meet his burden when he received
    exactly the benefit his attorney had spent months negotiating on his behalf.
    Indeed, at sentencing, DiFalco's attorney actually thanked the government for
    agreeing to the plea agreement with DiFalco rather than seeking the mandatory life
    sentence DiFalco's lengthy criminal record entitled it to seek. Nor is there any
    dispute that DiFalco actually had multiple drug convictions that would expose him
    to an enhanced sentence. Even though the § 851 information in this case may have
    left something to be desired, the fairness, integrity, or public reputation ofthe
    judicial proceedings were in no way affected by holding DiFalco to the plea
    agreement he knowingly and voluntarily entered into.
    B.
    Next, DiFalco says that the information was neither filed timely nor served
    upon him because it was filed electronically on the district court's docket on the
    32
    Case: 15-14763     Date Filed: 09/20/2016    Page: 33 of 37
    same day as his plea hearing, but, notably, before he entered his plea.
    Section 851(a)(1)requires that the information be filed before trial or before the
    entry of a guilty plea. 21 U.S.C. § 851(a)(1). We have held that § 851 requires the
    information be filed and served before entry ofthe defendant's guilty plea. United
    States V. DuffV. 
    179 F.3d 1304
    , 1305 (11th Cir. 1999). Thus,even notice filed and
    served during the course ofthe plea hearing itself is timely provided it occurs
    before the district court accepts the defendant's guilty plea. Id Here,the record is
    clear that the notice was sent hours before the plea hearing and that notice had been
    sent to defense counsel electronically. Moreover, at the plea colloquy, the
    magistrate judge reminded everyone that the government had filed the § 851
    information without provoking any objection from DiFalco or his attorney. To the
    extent DiFalco argues that service was insufficient because it was not delivered by
    hand, we know of no requirement that a § 851 notice be delivered by hand as
    opposed to being delivered electronically. And,in any event, even ifsome error
    lurked in the process offiling or delivering the notice, the error could not have
    been plain or obvious in the absence of any law requiring that method of
    communication. See United States v. Schultz, 
    565 F.3d 1353
    , 1357(11th Cir.
    2009)("An error is not plain unless it is contrary to explicit statutory provisions or
    to on-point precedent in this Court ofthe Supreme Court."). Nor,finally, has
    DiFalco established his burden under plain error review ofshowing how his
    33
    Case: 15-14763     Date Filed: 09/20/2016    Page: 34 of 37
    substantial rights were affected, let alone that the fairness and integrity ofthe
    judicial proceeding had been undermined.
    C.
    DiFalco also argues that the magistrate judge erred by not informing DiFalco
    that his prior conviction subjected him to an enhanced mandatory minimum
    sentence. Under Fed. R. Crim P. 11, a judge accepting a guilty plea from a
    defendant is required to inform the defendant of, and determine that the defendant
    understands, the rights he is surrendering and the consequences of his plea as well
    as determining that the plea is voluntary. Fed. R. Crim. P. 11(b). A judge is not
    required to recite the list in Rule 11 verbatim, so long as he covers the substance of
    the issues presented in the Rule. Monroe,353 F.3d at 1351. Thus, at bottom,the
    judge must determine that(1)the guilty plea is free from coercion;(2)the
    defendant understands the nature ofthe charges; and(3)the defendant understands
    the consequences of his guilty plea. United States v. Gandy,710 F.3d 1234,1240
    (11th Cir. 2013); Monroe,353 F.3d at 1354. To show that the judge committed
    plain error under Rule 11, a defendant must show,among other things, a
    reasonable probability that he would not have entered the plea but for the error.
    Gandv,710 F.3d at 1240.
    DiFalco has not shown that the magistrate judge committed any error at all
    in conducting the Rule 11 colloquy, let alone plain error. First, contrary to
    34
    Case: 15-14763     Date Filed: 09/20/2016    Page: 35 of 37
    DiFalco's claim, the magistrate judge informed him that his prior drug conviction
    subjected him to an enhanced minimum sentence. DiFalco said that he understood
    when the magistrate told him that, should he go to trial,"the government would be
    required to prove that[he had] a prior conviction for a felony drug offense
    subjecting [him]to the minimum mandatory enhancement." Moreover,the plea
    colloquy addressed the core concerns of Rule 11. The magistrate judge reviewed
    the penalties DiFalco faced, noting that the government had filed a notice of
    information saying that DiFalco had a prior drug conviction and potentially faced
    an enhanced sentence of20 years to life in prison. Neither DiFalco nor his
    attorney indicated any confusion regarding his prior conviction or the
    consequences it would carry for his sentence. DiFalco also affirmed that he had
    not been promised anything different from his plea agreement, that he had not been
    threatened into pleading guilty, and that he had decided to plead guilty only after
    counseling with his attorney. Moreover,DiFalco has not even suggested that he
    would not have pled guilty but for the claimed error in the plea colloquy. Indeed,
    his attorney spent months diligently negotiating the beneficial plea deal he
    received.
    D.
    Finally, DiFalco argues that the district court erred by failing to engage in a
    § 851(b)inquiry. Section 851(b)directs a district court to inquire ofa defendant
    35
    Case: 15-14763     Date Filed: 09/20/2016   Page: 36 of 37
    against whom a § 851 information has been filed whether he affirms or denies that
    he was previously convicted as alleged in the information. 21 U.S.C. § 851(b).
    But § 851(b) need not be complied with in all cases. Indeed,"[a] trial court is not
    required 'to adhere to the rituals of§ 851(b) where a defendant, as a matter oflaw,
    is precluded [by § 851(e)]from attacking the conviction forming the basis ofthe
    enhancement information.'"Weaver.905 F.2d at 1482(quoting United States v.
    Nanez.694 F.2d 405,413(5th Cir. 1982)); accord United States v. Williams.438
    F.3d 1272,1274(11th Cir. 2006). Section 851(e)provides that"[n]o person who
    stands convicted of an offense under this part may challenge the validity of any
    prior conviction alleged under this section which occurred more than five years
    before the date ofthe information alleging such prior conviction." 21 U.S.C.
    § 851(e). DiFalco's conviction occurred in 2002, more than five years before the
    government filed its § 851 notice. Even the incorrect conviction date cited by the
    government in its information was more than five years before the government
    filed the information. Because the conviction occurred more than five years before
    the date ofthe information alleging the prior conviction, DiFalco was barred from
    phallffnging the Validity ofthat conviction under § 851(e). See Williams,438 F.3d
    at 1274; Weaver.905 F.2d at 1482. Thus, we can discern no error-let alone plain
    error — in the district court's failure to engage in a § 851(b)inquiry.
    36
    Case: 15-14763     Date Filed: 09/20/2016   Page: 37 of 37
    Accordingly, even ifDlFalco has not waived his right to contest his
    sentence, the judgment ofthe district court must be afiSrmed.
    DISMISSED.
