    OPINION OF THE COURT
    WEIS, Circuit Judge.
    In this section 2255 case, defendant contends that his
    trial counsel erred in failing to object at sentencing to the
    use of incriminating admissions made as part of a
    cooperation agreement with the government and immunized
    by U.S.S.G. S 1B1.8. We conclude that the government had
    promised that such information would not be used to
    increase the defendant's punishment. Consequently, that
    material should not have been factored into the sentence.
    Whether counsel's inaction at sentencing constitutes
    ineffective assistance requires a hearing. Accordingly, we
    will remand for that purpose.
    Defendant John Baird pleaded guilty to a Hobbs Act
    robbery, 18 U.S.C. S 1951; conspiracy to violate civil rights,
    id. S 241; and obstruction of justice. Id. S 1503. These
    charges grew out of the defendant's misconduct as an
    officer in the Philadelphia Police Department. After he
    became aware that he was under investigation, defendant
    cooperated extensively with federal authorities in exposing
    corruption in the department. A more comprehensive review
    of the facts underlying this case may be found in the
    defendant's direct appeal. United States v. Baird, 
    109 F.3d 856
     (3d Cir. 1997).
    2
    At sentencing, despite the fact that the prosecution had
    filed a section 5K1.1 motion recommending a downward
    departure, the court departed upwards from the guideline
    range of 87-108 months to 156 months. The sentence
    reached was based, in part, on conduct underlying counts
    that had been dismissed pursuant to a plea bargain, as
    well as on information provided by defendant as he had
    agreed.
    At the sentencing hearing, counsel argued that the
    defendant's own statements had unfairly resulted in a
    higher guideline calculation, but she did not clearly
    challenge the use of that material. Neither did she object on
    the basis of U.S.S.G. S 1B1.8, which generally immunizes
    from sentencing the consideration of self-incriminating
    information provided pursuant to an applicable cooperation
    agreement.
    On direct appeal, defendant contended that the District
    Court erred at sentencing by considering activity underlying
    the dismissed counts. We affirmed, concluding that such
    conduct could support the upward departure. Baird, 
    109 F.3d at 863
    . As a result of post-sentencing assistance, the
    defendant's sentence was later reduced to 126 months.
    Defendant then filed the present motion under 28 U.S.C.
    S 2255, asserting that his trial counsel had been ineffective
    by failing to challenge the adverse use of information that,
    he argued, was immunized by his cooperation agreement
    and section 1B1.8. The District Court denied the motion,
    noting that in the early stages of his cooperation, defendant
    had attempted to falsely exculpate a fellow officer. Although
    the cooperation agreement "would have kept all his self-
    incriminating statements out [so] they could not have been
    used against him," the court concluded that the defendant's
    attempts to shield a co-conspirator "breached the deal" and
    "rendered it null." Accordingly, reasoned the District Court,
    section 1B1.8(a) was never triggered because the
    defendant's "own actions . . . caused the agreement to self-
    destruct."
    In this appeal, defendant renews his contention that the
    government promised that the self-incriminating material
    he disclosed would not be used for sentencing purposes.
    3
    The government counters that it made no such
    commitment, and in the alternative, contends that
    defendant breached any purported agreement.
    I.
    To prevail in his contention that counsel was ineffective,
    defendant must show both deficiency in performance and
    prejudice. Strickland v. Washington, 
    466 U.S. 668
    , 700
    (1984). The "deficiency" step asks whether counsel's
    conduct "fell below an objective standard of
    reasonableness" viewed as of the time it occurred. 
    Id. at 688, 690
    ; see also United States v. Gray, 
    878 F.2d 702
    , 711
    (3d Cir. 1989). The "prejudice" prerequisite asks whether
    "there is a reasonable probability that, but for counsel's
    unprofessional errors, the result of the proceeding would
    have been different." Strickland, 
    466 U.S. at 694
    ; see also
    United States v. Headley, 
    923 F.2d 1079
    , 1083 (3d Cir.
    1991).
    As a threshold matter, the court must determine whether
    the underlying claim was meritorious. United States v.
    Mannino, ___ F.3d ___, No. 98-1748, 
    2000 WL 583645
    , at *3
    (3d Cir. May 15, 2000). The underlying facts are reviewed
    for clear error, and are subject to independent judgment
    "on whether the facts thus found constitute constitutionally
    ineffective assistance of counsel." Government of the Virgin
    Islands v. Weatherwax, 
    77 F.3d 1425
    , 1430-31 (3d Cir.
    1996).
    An understanding of the defendant's section 2255 motion
    requires a review of the proceedings leading up to his
    sentencing. In early December 1994, having learned that he
    was about to be indicted for conspiracy to violate civil
    rights, defendant offered to cooperate with the government.
    Unrepresented by counsel, he signed a brief note prepared
    by an assistant United States Attorney indicating that "no
    statements made by you, or other information provided by
    you during the ``off-the-record' proffer, will be used directly
    against you in any criminal case."
    Two days later, on December 9, 1994, and still
    unrepresented, he signed a more formal letter drafted by
    the United States Attorney's Office. The letter acknowledged
    4
    the defendant's desire to cooperate and stated that the
    earlier "off-the-record" note no longer applied and "[f]rom
    now on," information furnished was "on the record, and
    could be admitted against you in the future if you failed to
    plead guilty" to a Hobbs Act robbery and a conspiracy to
    violate civil rights. The letter also noted that cooperation
    could result in a governmental motion for a downward
    departure.
    In the month following, defendant fabricated evidence to
    exculpate a co-conspirator, Thomas G. DeGovanni. On
    January 28, 1995, defendant admitted this deception, and
    later aided the government in obtaining evidence
    incriminating DeGovanni. There is no evidence or
    suggestion that defendant took further steps to improperly
    exculpate himself or others, or to minimize his role in the
    offenses.
    At some point not disclosed by the record, defendant
    retained counsel. On February 28, 1995, a multi-count
    indictment was returned against defendant, DeGovanni,
    and others. In addition to the two offenses enumerated in
    the December 9 letter, the indictment included four other
    charges against defendant, including a count for
    obstruction of justice stemming from his attempted cover-
    up of DeGovanni.
    With defendant now represented, the parties entered into
    a more detailed, formal plea agreement on March 30, 1995.
    Defendant agreed to cooperate by disclosing information
    and testifying if necessary. He also agreed that if he
    committed any additional crimes, the government could
    avoid the agreement. In due course, defendant pleaded
    guilty to counts alleging violations of the Hobbs Act,
    conspiracy, and obstruction of justice. A presentence report
    was prepared.
    In moving for a downward departure at sentencing, the
    assistant United States Attorney stated that defendant had
    "demonstrated a remarkable degree of both candor and
    recall." Moreover, declared the prosecutor, it was "difficult
    to conceive that a similarly situated defendant could
    provide a more substantial level of cooperation in the
    development of an historical case of police corruption." The
    5
    sentencing judge was nevertheless struck by the
    extraordinary disruption of the criminal justice system
    caused by the defendant's conduct, and decided to depart
    upward. Acknowledging the government's section 5K1.1
    motion, the judge stated that he was giving an "implicit"
    downward departure in that he "would be hitting
    [defendant] harder . . . were it not for the cooperation."
    In its response to the section 2255 motion in the District
    Court, the government conceded that the defendant's
    "sentencing guideline calculation and [the District Court's]
    determination to depart upward were based upon matters
    which included in large part information obtained directly
    from [defendant]." The presentence report recites in
    considerable detail numerous instances in which defendant
    and his co-conspirators "participated in illegal searches of
    individuals and property, made illegal entries into premises,
    made illegal detentions, used unwarranted force and threat
    of force against detainees and stole money and property
    . . . ."
    The probation officer relied on these incidents in
    recommending upward departures, stating that the
    defendant's actions had significantly disrupted
    governmental functions, had led to the imprisonment of
    many individuals in violation of their civil rights, and had
    caused many convictions to be overturned. The government
    alluded to such matters in its sentencing memorandum,
    stating that "the District Attorney's Office was left in the
    unenviable position of having to concede the vacating of
    convictions of literally dozens of drug dealers." The
    memorandum noted the irony that the defendant's
    cooperation had widened the scope of culpable conduct
    before the court.
    The District Court considered such incidents in reaching
    its sentencing decision, finding that there had been "many
    significant disruptions of many Governmental functions,"
    and that "many of these illicit searches" were later
    overturned.
    II.
    In the defendant's direct appeal, we held that evidence
    underlying dismissed counts was properly considered in the
    6
    sentencing process. Baird, 
    109 F.3d at 863
    . The question
    here is quite different and is based on U.S.S.G.S 1B1.8, a
    guideline provision that excludes certain information from
    a court's consideration of the sentence to be imposed.
    Traditionally, judges exercised wide discretion over the
    source and type of material used to determine punishment.
    Williams v. New York, 
    337 U.S. 241
    , 246 (1949). This broad
    authority was codified in 18 U.S.C. S 3577, later
    renumbered as 18 U.S.C. S 3661, which states that "[n]o
    limitation shall be placed on the information concerning the
    background, character, and conduct of a person convicted
    of an offense which a court of the United States may receive
    and consider for the purpose of imposing an appropriate
    sentence." This language is quite broad and facially, would
    appear to bar redaction of information furnished by a
    cooperating defendant.
    In the Sentencing Reform Act of 1984, however, Congress
    subsequently established the United States Sentencing
    Commission and guideline system, 28 U.S.C. SS 991,
    994(a)(1), and directed that certain factors not be included
    in sentencing calculations. 
    Id.
     S 994(d), (e). It also directed
    that the Commission pay "particular attention" to
    "providing certainty and fairness in sentencing." 
    Id.
     S 994(f).
    Among those factors which were to be used to reduce a
    sentence, the statute listed "a defendant's substantial
    assistance" to the government. 
    Id.
     S 994(n). Guidelines
    section 1B1.8, which ensures that cooperating witnesses
    generally do not face increased sentences because of their
    cooperation, thus satisfies the mandate in section 994(n)
    that, where appropriate, substantial assistance be rewarded
    by a reduced sentence.
    As an additional phase of the sentencing legislation, 18
    U.S.C. S 3553(b) provides that aggravating or mitigating
    factors not taken into account by the Sentencing
    Commission may be used in determining an appropriate
    sentence. See also Williams v. United States, 
    503 U.S. 193
    ,
    200 (1992) (noting that the sentencing court may not
    depart based "on a factor that the Commission has
    expressly rejected as an appropriate ground for departure").
    When read in conjunction with that provision, section 3661
    is thus a "safety net . . . . mak[ing] available for sentencing
    7
    any relevant information not considered by the guidelines."
    United States v. Fairman, 
    947 F.2d 1479
    , 1482 (11th Cir.
    1991). As we stated in United States v. Bruno , 
    897 F.2d 691
    , 695-96 (3d Cir. 1990), the two "sections are to operate
    in harmony," and information of the type encompassed by
    section 3661 is subject to the limitations of section 3553(b).
    In short, reading section 3661 together with the other
    provisions of the Sentencing Reform Act, including the
    requirements specifically articulated by Congress, leads us
    to conclude that U.S.S.G. S 1B1.8, while limiting the
    otherwise-comprehensive language of section 3661, is
    enforceable.
    We turn then to the guideline at issue. Section 1B1.8(a)
    states:
    Where a defendant agrees to cooperate with the
    government by providing information concerning
    unlawful activities of others, and as part of that
    cooperation agreement the government agrees that self-
    incriminating information provided pursuant to the
    agreement will not be used against the defendant, then
    such information shall not be used in determining the
    applicable guideline range, except to the extent
    provided in the agreement.
    U.S.S.G. S 1B1.8(a).
    There are several caveats to the general rule. Immunity
    shall not apply "in the event there is a breach of the
    cooperation agreement by the defendant." Id . S 1B1.8(b)(4).
    Other exceptions include information "known to the
    government prior to entering into the cooperation
    agreement," 
    id.
     S 1B1.8(b)(1), and information used "in
    determining whether, or to what extent, a downward
    departure from the guidelines is warranted . . . under
    S5K1.1." 
    Id.
     S 1B1.8(b)(5). As a corollary, however, the
    Commission's policy is that self-incriminating information
    "shall not be used to increase the defendant's sentence
    above the applicable guideline range by upward departure."
    
    Id.
     S 1B1.8 applic. n.1. The ban on the use of incriminatory
    evidence applies not only to government attorneys, but also
    to probation officers in the preparation of presentence
    reports. 
    Id.
     S 1B1.8 applic. n.5; see also United States v.
    Fant, 
    974 F.2d 559
    , 564 (4th Cir. 1992).
    8
    Courts have set aside sentences based on incriminating
    information obtained from a defendant where there were
    explicit references to section 1B1.8 in the plea or
    cooperation agreements. United States v. Washington, 
    146 F.3d 219
    , 220, 223 (4th Cir. 1998). In other cases, the
    existence or scope of a cooperation agreement was at issue.
    At a minimum, the court must find an agreement that 1)
    defendant will cooperate "by providing information
    concerning the unlawful activities of others"; and 2) the
    government will not use the self-incriminating information
    provided thereto against defendant. United States v. Evans,
    
    985 F.2d 497
    , 499 (10th Cir. 1993).
    A failure to be explicit or to cite to section 1B1.8 will not
    by itself vitiate a purported cooperation agreement. In
    United States v. Shorteeth, 
    887 F.2d 253
     (10th Cir. 1989),
    the government had promised not to institute additional
    prosecutions based on information received from the
    defendant. The court concluded that this agreement
    embodied an implicit promise not to use that evidence in
    calculating the sentencing range, stating that "the language
    and spirit of Guidelines S 1B1.8 require the agreement to
    specifically mention the court's ability to consider
    defendant's disclosures during debriefing in calculating the
    appropriate sentencing range before the court may do so."
    
    Id. at 257
    .
    But where an agreement does not embrace immunizing
    consequences, courts will not read them in. See United
    States v. Ykema, 
    887 F.2d 697
    , 699 (6th Cir. 1989)
    (concluding that mere promise that "no additional charges"
    would be brought did not preclude sentence based on drug
    quantity higher than that stipulated in plea agreement). But
    cf. United States v. Kinsey, 
    917 F.2d 181
    , 184 (5th Cir.
    1990) (although promise not to prosecute did not appear to
    be ban on use of self-incriminating material, court accepted
    the parties' mutual understanding that agreement
    incorporated such a promise).
    Similarly, where a cooperation arrangement exists, but
    clearly limits the boundaries of immunity, courts are chary
    of expanding upon the parties' clear intentions. See United
    States v. Fontana, 
    50 F.3d 86
    , 87-88 (1st Cir. 1995)
    ("single, limited[ ] promise" of immunity for evidence of
    9
    amount of counterfeit money did not extend to information
    on cohort's identity); United States v. Stevens , 
    918 F.2d 1383
    , 1387 (8th Cir. 1990) (despite assertion that higher
    drug quantity could not be considered under cooperation
    agreement, defendant voluntarily stipulated to higher
    amount in superseding plea agreement).
    Whether the government has violated a plea, or by
    analogy, a cooperation agreement, is a question of law
    subject to de novo review. United States v. Huang, 
    178 F.3d 184
    , 187 (3d Cir. 1999). Whether any such agreement
    exists is also a question of law with the underlying facts
    found by the District Court reviewed for clear error. ATACS
    Corp. v. Trans World Comm., Inc., 
    155 F.3d 659
    , 665 (3d
    Cir. 1998).
    Although a cooperative plea agreement is not altogether
    the same as a commercial arrangement, civil contract law
    is nevertheless an important and useful aid in
    interpretation. Huang, 
    178 F.3d at
    187-88 (citing United
    States v. Khan, 
    920 F.2d 1100
    , 1105 (2d Cir. 1990)); see
    also United States v. Nolan-Cooper, 
    155 F.3d 221
    , 236 (3d
    Cir. 1998) (plea agreements construed according to contract
    principles); United States v. Isaac, 
    141 F.3d 477
    , 483 (3d
    Cir. 1998); United States v. Moscahlaidis, 
    868 F.2d 1357
    ,
    1361 (3d Cir. 1989).
    The government may not rely upon a rigid and literal
    construction of the terms of a plea or cooperation
    agreement. Nolan-Cooper, 
    155 F.3d at 236
    . Such
    agreements are unique and are to be construed in light of
    "special due process concerns." United States v. Bradbury,
    
    189 F.3d 200
    , 206 (2d Cir. 1999) (internal quotes omitted).
    Courts must determine whether the government's conduct
    was inconsistent with what was reasonably understood by
    defendant when entering the plea of guilt. United States v.
    Badaracco, 
    954 F.2d 928
    , 939 (3d Cir. 1992); Bradbury,
    
    189 F.3d at 206
    . In view of the government's tremendous
    bargaining power, we will strictly construe the text against
    it when it has drafted the agreement. United States v.
    Padilla, 
    186 F.3d 136
    , 140 (2d Cir. 1999).
    As is apparent from the text of guideline section 1B1.8(a),
    there is a threshold inquiry of whether the government
    10
    promised to immunize the defendant's incriminating
    statements. We thus begin with the letter of December 9,
    1994. As noted earlier, it states that "[f]rom now on, any
    statements, documents, tape recordings or other
    information which you may provide is on the record, and
    could be admitted against you in the future if you failed to
    plead guilty to the offenses" enumerated in the agreement.
    That clause is the focal point of the dispute. Defendant
    reads it to mean that information garnered from his
    assistance could be used against him only if he failed to
    plead guilty to the offenses described in the letter. In his
    view, the phrase "if you failed to plead guilty" creates a
    condition precedent to the use of any incriminating
    information against him. The government, in contrast,
    takes the position that all information was "fully on the
    record," and that the now-disputed statement was merely a
    warning of the consequences of a failure to plead, and not
    a promise to immunize cooperation evidence upon entry of
    a guilty plea.
    We reject the government's reading. Construing
    ambiguity against the government, we conclude the
    agreement states that if defendant did plead guilty, the
    information would not be used "against [him] in the future."
    We are persuaded that reasonable persons would
    understand the challenged clause to mean that
    incriminating information would not be admitted against
    defendant in any proceeding, including his own sentencing,
    if he pleaded guilty to the designated offenses.
    Having determined that an agreement exists, we must
    next consider whether defendant breached it, and if so,
    whether it remained in force. After the letter was signed,
    defendant attempted to shield his fellow officer DeGovanni.
    Nevertheless, even while attempting to aid DeGovanni,
    defendant was simultaneously providing information to
    incriminate other members of the police force.
    It seems clear that the effort to aid DeGovanni was at
    least a partial breach of that agreement and defendant does
    not appear to contend otherwise. Upon learning of the
    defendant's duplicity, the government might have declared
    a breach of the agreement and either attempted to sever its
    11
    relationship with defendant or to negotiate a new
    arrangement disavowing the earlier one. That, however,
    does not seem to have occurred. Instead, defendant agreed
    to plead to an additional count for obstruction of justice,
    but significantly, continued his cooperation.
    The next important development is the execution of the
    formal plea agreement on March 30, 1995. Paragraph 2(j) of
    that document has particular relevance:
    Defendant agrees that if the government determines
    that the defendant . . . has committed any federal,
    state or local crime between the date of this agreement
    and his sentencing, . . . the agreement may be voided
    by the government and the defendant shall be subject
    to prosecution for any federal crime of which the
    government has knowledge including, but not limited
    to, perjury, obstruction of justice, and the substantive
    offenses arising from this investigation. This
    prosecution may be based upon any information
    provided by the defendant during the course of his
    cooperation, and this information may be used as
    evidence against him.
    This provision means that if defendant engaged in
    criminal conduct after signing the plea agreement, the
    government could use any information supplied by
    defendant against him. By negative implication, as in the
    instance of the December 9 letter, the government agreed
    as a general matter not to use to the defendant's detriment
    information obtained through the cooperation process.
    Thus, the plea agreement was consistent with the
    December 9 letter of immunity.
    We note that paragraph 4(d) of the plea agreement
    indicates that the government could "bring to the Court's
    attention all facts relevant to sentencing (including evidence
    relating to the character of the defendant)." This provision,
    of course, begs the question of what facts are "relevant" to
    sentencing. By agreeing to immunize self-incriminating
    information, the government has limited the scope of
    information that may be considered at sentencing. We
    therefore do not understand this provision to provide an
    end-run around the cooperation agreement.
    12
    Reading the formal plea agreement against the
    government as the drafter, and in light of its acceptance of
    the plea to obstruction of justice as an apparent cure of the
    initial breach, we conclude that the government treated the
    December 9 agreement as remaining in effect. That
    conclusion is not altered by the plea agreement's
    integration clause, which states that "no additional
    promises, agreements or conditions have been entered into
    other than those set forth in this document . . . ." This
    obvious boilerplate does not contain language purporting to
    supersede the December 9 letter. Further, the two
    documents may be read consistently with one another. In
    light of these considerations and the special due process
    concerns in the criminal arena, the integration clause has
    no effect in this context.
    Having concluded that there has been a breach, an
    apparent cure, and a conceded continuation of the
    cooperation, we must determine whether the District Court
    was correct in declaring the agreement null and void. In
    contract law, the effect of a breach is a frequently litigated
    issue. The question is often whether the agreement is
    absolutely and automatically dissolved on the occurrence of
    an event, i.e., void, or whether one party's action gives the
    other the option to declare the agreement at an end, i.e.,
    voidable.
    As expressed by a recognized authority on contracts,
    "[u]ntil the party who has the power of avoidance elects to
    exercise it, the contract remains intact. Moreover, even
    though one of the parties has the power of avoidance, he
    may extinguish that power by ratification of the contract."
    John E. Murray, Jr., Murray on ContractsS 17, at 31 (3d
    ed. 1990). On the other hand, " ``[v]oid' contracts are not
    contracts at all" and any promise therein is unenforceable.
    Id. at 32; see also Restatement of Contracts (Second) S 7
    (1981); E. Allan Farnsworth, Contracts S 4.10, at 243-44 (3d
    ed. 1999); 1 Joseph M. Perillo, Corbin on Contracts SS 1.6-
    1.7 (rev. ed. 1993).
    Although the District Court characterized the plea
    agreement as "null," it is clear that if there was a contract,
    it would be voidable, not void. Moreover, in the criminal
    context, if a breach is to be remedied by a subsequent
    13
    agreement, the defendant should receive an adequate
    warning of the consequences. Bradbury, 
    189 F.3d at 208
    .
    Failure to provide adequate notice of a breach would
    undercut one of the " ``most important advantages' " of
    section 1B1.8, that " ``prosecutors can . . . assure potential
    informants that their statements will in no way be used
    against them.' " 
    Id. at 208
     (quoting Shorteeth, 
    887 F.2d at 257
    ) (alteration in original). The record before us does not
    reveal any warning to defendant as to the consequences of
    his breach. Instead, the government continued to reap
    substantial benefits from his cooperation.
    In sum, construing the documents against the drafter, we
    conclude that the government agreed not to use
    information defendant provided against himself at
    sentencing. The government accepted the defendant's guilty
    plea to obstruction of justice as a satisfaction of the breach
    and did not attempt to avoid the December 9 agreement. It
    further appears that the government's performance in
    continuing the cooperation arrangement without any
    warning to defendant that its former promise no longer
    applied constituted a waiver of the breach. Consequently,
    the District Court erred in ruling that the cooperation
    agreement was a nullity.
    At this stage, defendant has laid the groundwork for a
    meritorious claim, but we caution that the record is not
    complete. Immunity does not extend to material known to
    the government before it entered into the cooperation
    agreement. U.S.S.G. S 1B1.8(b)(1); United States v. Wilson,
    
    106 F.3d 1140
    , 1144 n.5 (3d Cir. 1997). Nor would it
    generally apply to disclosures made during the plea
    colloquy.
    Also, information post-dating the agreement and obtained
    from independent sources is not barred. United States v.
    Gibson, 
    48 F.3d 876
    , 879 (5th Cir. 1995). Information
    separately gleaned from co-defendants is also fair game,
    United States v. Davis, 
    912 F.2d 1210
    , 1213 (10th Cir.
    1990), and the defendant's later corroboration does not
    remove the co-defendant's evidence from consideration.
    United States v. Boyd, 
    901 F.2d 842
    , 845 (10th Cir. 1990).
    But the government may not evade U.S.S.G. S 1B1.8(a)
    where the evidence was elicited solely as a result of, or
    14
    prompted by, the defendant's cooperation. Davis , 
    912 F.2d at 1213
    ; see also Gibson, 
    48 F.3d at 878
    .
    The sources of the information utilized in the sentencing
    calculation in this case may only be resolved by a hearing
    on remand. Bradbury, 
    189 F.3d at 208
    ; United States v.
    Amato, 
    46 F.3d 1255
    , 1262-63 (2d Cir. 1995); Kinsey, 
    917 F.2d at 184
    .
    III.
    We also note that the record is insufficient to establish
    whether the conduct of trial counsel satisfies Strickland's
    deficiency requirement, i.e., that the representation fell
    below the competence of attorneys in criminal cases.
    Strickland, 
    466 U.S. at 688
    . As one facet of this inquiry, we
    point out that under Burns v. United States, 
    501 U.S. 129
    ,
    138-39 (1991), a District Court must notify the parties in
    advance of sentencing if it intends to depart upwards on
    grounds not set out in the presentence report or the
    government's submission. United States v. Barr , 
    963 F.2d 641
    , 655 (3d Cir. 1992); see also United States v. Hecht, ___
    F.3d ___, No. 99-1543, 
    2000 WL 637396
    , at *2 (3d Cir. Feb.
    29, 2000). The record before us does not indicate whether
    such notice was given, or if it was required here.
    Because the record contains no evidence on the reasons
    underlying counsel's decision not to challenge the
    presentence report or sentence on section 1B1.8 grounds,
    a hearing is required on that point as well.
    Defendant has presented a prima facie claim of prejudice,
    but that too must be fleshed out on remand. Defendant
    must show that "but for counsel's unprofessional errors,
    the result of the proceeding would have been different."
    Strickland, 
    466 U.S. at 694
    . The determination of prejudice
    "should not depend on the idiosyncracies of the particular
    decisionmaker," and should instead "proceed on the
    assumption that the decisionmaker is reasonably,
    conscientiously, and impartially applying the standards
    that govern the decision." 
    Id. at 695
    . Whether the
    defendant's prima facie claim can be rebutted by the
    government will have to be determined on remand.
    15
    Accordingly, the order of the District Court will be
    reversed and the case will be remanded for further
    proceedings consistent with this Opinion.
