FLETCHER, Circuit Judge:
The Government appeals the district court’s downward departure from the Sentencing Guidelines in sentencing career offender Reyes. It argues that the district court ignored the career, offender guideline' provisions, U.S.S.G. § 4B1.1, by departing from a sentencing range of 210-262 months and setting a sentence of thirty-three months. Reyes cross-appeals the district court’s failure to allow a waiver of jury trial under Fed.R.Civ.P. 23. Defendant argues that the court should have required the Government to articulate a non-racial motive for its refusal to consent to waiver. The district court had jurisdiction pursuant to 18 U.S.C. § 3231. The jurisdiction of this court rests on 18 U.S.C. § 3742(b) (Sentencing Guidelines) and 28 U.S.C. § 1291 (Final Judgments).
FACTS
Armando Reyes, a twenty-nine-year-old citizen of Mexico, illegally crossed the border to the United States at the age of fourteen. He has been deported to Mexico four times, the last as the result of a felony drug conviction. (PSR 3). In October 1990, within two months following his most recent deportation, he was arrested by the Portland Police Bureau for selling 2.8 grams of marijuana in the Old Town section of Portland. At that time another 2.7 grams of marijuana was found in his possession. Over a month later, in November 1990, Reyes sold .14 grams of cocaine to an undercover officer. Prior to arrest he swallowed the remaining drugs in his possession.
The Government became involved in this case upon the discovery of Reyes’ status as an illegal alien. It brought a three-count Grand Jury Indictment for distributing marijuana (under 21 U.S.C. § 841(a)(1)), distributing cocaine (also under 21 U.S.C. § 841(a)(1)), and for illegal reentry (under 8 U.S.C. § 1326). Reyes filed a trial memorandum waiving his right to a jury trial and requesting that the court order a bench trial over the Government’s objection. The court denied the request and the jury found Reyes guilty on all three counts.
According to the presentence report, Reyes has been arrested and sentenced for six other offenses: (1) in 1984 in California for use of opiates; (2) in 1987 in California for possessing for sale of six “baggies” of marijuana; (3) in 1987 in Washington for attempted theft from a department store; (4) in 1987 in Washington for obstructing a public officer; (6) in 1989 in Oregon for possession of drugs (including .45 grams of cocaine and .10 grams of heroin); and (6) in 1989 in Oregon for possessing and delivering $20-worth of cocaine.1 The probation officer computed Reyes’ criminal history and offense level points without reference to the career offender provisions of the guidelines. He assigned Reyes a base offense level of twelve, adjusting it to fourteen for multiple counts, and calculated criminal history points of twelve, placing Reyes in criminal history category V. The resulting guideline range was 33-41 months.
[1382]*1382In its objections to the report, the Government pointed out that the previous drug-related offenses triggered the application of the career offender provisions, U.S.S.G. § 4B1.1.2 Under these provisions, because the offense of conviction3 was subject to a maximum statutory penalty of twenty years, 21 U.S.C. § 841(b)(1)(C), Reyes qualified for a base offense level of thirty-two. As a career offender, he automatically fell within criminal history category VI. The career offender sentencing range is 210-262 months, producing a choice of sentences almost seven times as long as those applicable under non-career offender guidelines.
The probation officer did not modify his prior report and recommendation. The report recommended that if the career offender provisions were found to apply, a downward departure be made from the applicable range. The sentencing judge agreed with the Government that the career offender provisions applied to Reyes, but, on the recommendation of the probation officer and defense counsel, departed from the career offender range and fixed a sentence of thirty-three months. He also ordered a three-year term of supervised release and participation in a substance abuse treatment program.
STANDARDS OF REVIEW
Under the three-part standard of review set forth for downward departures from the Sentencing Guidelines by United States v. Lira-Barraza, 941 F.2d 745, 746-47 (9th Cir.1991) (en banc); United States v. Valdez-Gonzalez, 957 F.2d 643 (9th Cir.1992); United States v. Floyd, 945 F.2d 1096, 1098-99 (9th Cir.1991), the panel must (1) review de novo whether the district court was authorized to depart downward from the career offender section of the guidelines; (2) review for clear error factual findings supporting the existence of circumstances which justify downward departure; (3) review for abuse of discretion the reasonableness of the extent of departure within the meaning of 18 U.S.C. §§ 3742(e)(3) and (f)(2). United States v. Martinez-Gonzalez, 962 F.2d 874 (9th Cir.1992).
Whether the district court should have allowed the defendant to waive trial by jury over the objection of the Government is a question of law and subject to de novo review. United States v. McConney, 728 F.2d 1195, 1200-1201 (9th Cir.), cert. denied 469 U.S. 824, 105 S.Ct. 101, 83 L.Ed.2d 46 (1984).
DISCUSSION
I. DOWNWARD DEPARTURE FROM CAREER OFFENDER CATEGORY
In accordance with its mandate from Congress,4 the Sentencing Guidelines Commission set forth provisions to enhance substantially the sentences received by career offenders, including “repeat drug offenders” and “repeat drug traffickers.”5 Under the guidelines:
A defendant is a career offender if (1) the defendant was at least eighteen years old at the time of the instant offense, (2) the instant offense of conviction is a felony that is either a crime of violence or a controlled substance offense, and (3) the defendant has at least two prior felony convictions of either a crime of violence or a controlled substance offense.
U.S.S.G. § 4B1.1. Although the career offender guidelines do not set out particular grounds upon which a court may depart downward from recommended sentencing ranges, the Ninth Circuit and other circuits [1383]*1383have held that the sentencing judge may “rely on ‘any ... policy statement ] or commentary in the guidelines that might warrant consideration in imposing sentence.’ ” United States v. Lawrence, 916 F.2d 553, 554 (9th Cir.1990) (citing U.S.S.G. § 1B1.1); see also United States v. Bowser, 941 F.2d 1019, 1023 (10th Cir.1991); United States v. Pinckney, 938 F.2d 519, 521 (4th Cir.1991); United States v. Adkins, 937 F.2d 947, 951 (4th Cir.1991); United States v. Senior, 935 F.2d 149, 151 (8th Cir.1991); United States v. Brown, 903 F.2d 540, 545 (8th Cir.1990). Since it is well established that a downward departure from career offender status is permissible, Lawrence, 916 F.2d at 554, we look only to the circumstances of this case to determine whether the district court’s stated basis for departure is appropriate.
In sentencing Reyes, the district court found the career offender guidelines applied. However, he explained:
I am going to depart downward to the level 14 and the range of 33 to 41 months. I think in this case it’s clear that the previous criminal history seriously overre-presents the history from the standpoint of the Guidelines. I can’t conceive that the Guidelines didn’t intend to give a judicial officer authority to depart downward under circumstances such as this. That being the case, I will depart.
Immediately before imposing this sentence the court noted that Reyes was guilty of very “minor offense[s],” and reasoned against sentencing “comparatively minor offenders ... to prison as long as the Guidelines would indicate.” (ER 20). Adopting the recommendation of the probation officer, the court relied on Sections 4A1.3 and 5K2.0 which authorize departure in “limited circumstances.” See United States v. Cruz-Ventura, 979 F.2d 146, 150 (9th Cir.1992) (citing United States v. Streit, 962 F.2d 894, 903 (9th Cir.1992)).
A. Appropriate Basis
Downward departure is not permitted unless the district court has identified a “mitigating circumstance of a kind or to a degree” the Sentencing Commission did not adequately take into account when formulating the guidelines. 18 U.S.C. § 3553(b); U.S.S.G. § 5K2.0. A reviewing court “must consider the reasons for departure actually articulated by the sentencing court.” United States v. Montenegro-Rojo, 908 F.2d 425, 427 (9th Cir.1990).6 “There is, however, no requirement that the sentencing judge recite the specific language of 18 U.S.C. § 3553(b),” the same language incorporated in Section 5K2.0. United States v. Sanchez, 933 F.2d 742, 745 (9th Cir.1991); United States v. Ramirez Acosta, 895 F.2d 597, 601 (9th Cir.1990).
Section 4A1.3 indicates that
[tjhere may be eases where the court concludes that a defendant’s criminal history category significantly over-represents the seriousness of a defendant’s criminal history.... The court may conclude that the defendant’s criminal history was significantly less serious than that of most defendants in the same criminal history category ... and therefore consider a downward departure from the guidelines.
In the district court’s view, Reyes’ criminal history suggested he was a “comparatively minor offender.” His conduct was not at all of the magnitude of seriousness of most career offenders. Reyes’ offenses involved considerably smaller amounts of drugs than those which would trigger the same sentence under the career offender provisions. Convicted for selling .14 grams of cocaine, he was subject to the same base offense level and sentencing range as if he had sold almost 4000 times that much. 21 U.S.C. § 841(b)(1)(C). Under the career offender guidelines a defendant convicted for a fraction of one gram of cocaine is accorded the harshest punishment due an offender trafficking in up to 500 grams. 21 U.S.C. [1384]*1384§ 841(b)(1)(C). Were he sentenced without reference to the career offender provisions, he would be subject to the same offense level and sentencing range as an offender associated with only up to twenty five grams of cocaine. See U.S.S.G. § 2D1.1(16). In Reyes’ case that would mean he and another offender of equivalent criminal history would be sentenced to the same punishment range for offenses involving only 200 times (rather than 4000) times as much cocaine.7
The Government formulates the stated basis for departure incorrectly. It focuses on the “small quantity” or “miniscule” amounts of drugs involved in Reyes’ offenses, choosing to state the court’s reason for departure as if it were a simple quantity-based argument fixing only upon the absolute amount of drugs at stake in the various offenses. The sentencing judge undertook a more nuanced approach based on comparison. Instead of emphasizing the absolute quantities of drugs involved, he cast the issue of quantity in comparative terms. Reyes’ criminal history was “comparatively minor.” His offenses were “minor” as compared to others (not small on some absolute scale). This approach focuses on quantity only as a means to analyze the comparative treatment of offenders. Quantity serves merely as the means to compare the similar treatment of defendants whose offenses differ by exceptional orders of magnitude.
Not crediting the court’s reason for departure, the Government argues that departure on the basis of the minuteness of the quantities is not permitted. It contends that the quantity of drugs involved cannot serve as a basis for departure because quantity already has been taken into consideration in the career offender provisions. Section 4B1.1 links base offense levels with the maximum statutory penalty available for the offense of conviction. If the defendant is convicted of an offense which subjects him to a minimum of five (but maximum of ten) year term, the career offender provisions assign him a base offense level of seventeen. If the defendant is subject to a minimum of ten (but maximum of fifteen) year term, he has a base offense level of twenty four. If he is subject to a minimum of fifteen (but maximum of twenty) year term, he is assigned an offense level of thirty-two. The chart is graduated in increments of five years of statutorily permitted penalties. Thus, while the guidelines themselves indicate no graduation based on quantities, the statutes they incorporate do. See e.g., 21 U.S.C. § 841(a). In the statutory context relevant here a penalty of five years attaches to drug convictions for anything less than fifty kilograms of marijuana;8 a penalty of twenty years for 50-100 kilograms of marijuana; 9 a penalty of forty years for 100 to 1000 kilograms of marijuana.10 Thus the Government argues, “[i]n drug cases, maximum penalties vary because [the penalty provision of the statute they depend upon] keys the maximum penalty to the quantity of drugs sold. Consequently, as drug quantities vary, so does the career offender’s offense level.” Appellant’s Opening Brief at 13. In its view this linked system for assigning one of the two elements11 necessary to determine a guideline sentencing range evidences adequate consideration of the quantities of drugs involved in offenses subject to the career offender provisions. It cites Second and Sixth Circuit precedent directly supporting its formulation and analysis of the “small-quantities” basis for departure. United States v. Richardson, 923 F.2d 13, 17 (2d Cir.1991) (Commission adequately took small quantities into account, downward departures for career offenders convicted for small amounts of drugs are not justified on these grounds); United States v. Hays, 899 F.2d 515, 518-520 (6th Cir.1990), cert. denied, 498 [1385]*1385U.S. 958, 111 S.Ct. 385, 112 L.Ed.2d 396 (1990) (same).
Because we conclude that the sentencing judge relied on a different basis for departure than the one described by the Government (and evaluated by Richardson and Hays'), our analysis is different. The question we address is not whether the career offender guidelines took into consideration small amounts of drugs, but whether it adequately considered the disproportionate treatment of drug offenders sentenced to the same penalty range for offenses involving drug quantities of exceptionally different orders of magnitude.12
A sentencing judge is “entitled to rely on ‘any ... policy statement ] or commentary in the guidelines that might warrant consideration in imposing sentence.’ ” Lawrence, 916 F.2d at 554 (citing U.S.S.G. § 1B1.1); Adkins, 937 F.2d at 951-52. One of the three principles upon which the Sentencing Guidelines is founded is “proportionality in sentencing through a system that imposes appropriately different sentences for criminal conduct of differing severity.” U.S.S.G. Ch. 1, Pt. A(3), intro, comment. This commitment to proportionality is reflected in the guideline provisions supporting the district court’s decision to depart. It undergirds Congress’s mandate that a court depart from the guidelines, not only if a “kind” of mitigating circumstance was not taken into account but if it was not taken into account to a sufficient “degree.” 18 U.S.C. § 3553(b); U.S.S.G. § 5K2.0. It is the reason for Section 4A1.3’s elaboration of the concept of over-representation in terms of recidivism and seriousness.13 Seriousness, in this context, is only defined comparatively. Finally, the introductory chapter to the guidelines announces a “heartland” approach to sentencing. Despite the fact that in certain circumstances “a particular guideline linguistically applies,” the guidelines specifically contemplate that “conduct significantly differing] from the norm” may warrant departure. U.S.S.G. Ch. 1, Pt. A intro. § 4(b); see also United States v. Bowser, 941 F.2d 1019, 1023 (10th Cir.1991).
In declaring that “comparatively minor offenders” should not receive the same “career offender status,” Transcript of Sentencing Proceedings at 25, the district court found the Commission’s consideration of the relationship between drug quantity and penalty among differently-situated career offenders inadequate. The “adequacy” enquiry goes to the comparative treatment of offenders with the same career offender base offense level, all of whom receive the same penalty range for very different amounts of drugs. On this view, the problem is not that the Commission did not take into consideration the relationship between quantity and penalty, but that it did not adequately do so because it did not focus sufficiently on the resulting disproportionate punishment accorded career offenders in the same category.14 Implicit in this [1386]*1386position is the conclusion that the penalty range is not sufficient to differentiate between two offenders with the same base offense level. The range afforded simply does not reflect the degree of differential in the seriousness of underlying criminal histories or offenses.15
We have noted that the Sentencing Act “ ‘creates a sentencing guidelines system that is intended to treat all classes of offenses committed by all categories of offenders consistently.’ ” (emphasis in original). Lira-Barraza, 941 F.2d at 748 (citing S.Rep. No. 225, 98th Cong., 1st Sess. 51, reprinted in 1984 U.S.C.C.A.N. 3234). In the context of the career offender provisions the Fourth Circuit has concluded that:
The test for “career offender” status is certainly ... fraught with potential imprecision ... [The] definition encompasses an enormous variety of crimes ... [and] there is clearly a potential for wide discrepancy in the gravity of past antisocial conduct among “career offenders.”
Adkins, 937 F.2d at 952 (emphasis added).
The Nichols district court mathematically evaluated the extent of potential imprecision flowing from certain applications of the career offender guidelines. United States v. Nichols, 740 F.Supp. 1332, 1337-38 (N.D.Ill. 1990), aff'd 937 F.2d 1257 (7th Cir.1991), cert. denied, — U.S. —, 112 S.Ct. 989, 117 L.Ed.2d 151 (1992). Defendant Nichols “face[d] a minimum sentence of 35 years for possessing a gun while also possessing less than a gram of cocaine that he intended to distribute.” Nichols, 740 F.Supp. at 1334. His prior offenses consisted of an assortment of residential burglaries, robbery, and auto theft. The court probed the relationship between the quantity of cocaine possessed by Nichols and quantities which could be possessed by another offender while still in the same base offense level and sentencing range. It concluded that although Congress had directed the Commission to sentence offenders at or near the maximum penalty authorized, it “would not have intended that somebody found guilty of intending to distribute less than one gram of diluted cocaine be sentenced at or near the maximum for intending to distribute nearly 500 grams of cocaine.” Nichols, 740 F.Supp. at 1337. On facts much less extreme than those presented by Reyes, the court found that a downward departure was warranted, in effect, because of the lack of proportionality.16
[1387]*1387We have approved departure based on dis-proportionality in other contexts. Where a district court found that the conduct of drug “mules” “significantly differ[ed] from the norm,” it departed on the ground that the mules’ relative blamelessness warranted commensurate treatment. Valdez-Gonzalez, 957 F.2d at 649-50; U.S.S.G. Ch. 1, Pt. A intro. § 4(b); see also Alschuler, supra note 15, 917, 926-927 (guidelines not “as successful in treating offenders of comparable culpability alike”). These drug offenders were not subject to the career offender guidelines and the court departed in part on the strength of the analogy between its stated reason and the “minimal role” adjustment allowed in other circumstances not obtaining in that case, e.g., U.S.S.G. § 3B1.2. Id. at 647-48. The sentencing judge here relied instead on the over-representativeness of Reyes’ career offender sentence range and the relative lack of seriousness of the offenses and history that put him into career offender status. Significantly, all these stated bases share a common thread — comparative evaluation and concern for proportionate treatment of offenders.
Nor is it the ease that every offender caught with small quantities of drugs will benefit from this evaluation. In the court’s estimation, Reyes’ criminal history differed from most other career offenders because it uniformly involved “minor” offenses. The facts of his case made application of a career offender sentence unusually over-representative. Other judges evaluating different criminal histories have found otherwise. The Whyte court reviewed the sentence of a defendant caught with forty-one grams of crack and ten grams of cocaine whose past offenses included the sale of $10 of marijuana and possession of “1500 doses” and “200 plastic packages” of marijuana. United States v. Whyte, 892 F.2d 1170, 1171-72 (3rd Cir.1989). Because the defendant had drawn a loaded gun on the police officer attempting to arrest him,, his record suggested “he would carry a weapon as part of whatever needs arise from dealing drugs on the street.” Id. at 1173 & n. 9. The district court concluded “I cannot conscientiously say that the defendant’s criminal history was significantly less than that of most defendants in the same criminal history category.” Id.
The court found that penalizing Reyes with the maximum term permitted for trafficking ordinarily reserved for drug quantities far in excess of the amounts for which he had been convicted (both in the instant and prior offenses) grossly over-represented the seriousness of his criminal history.17 While we agree that the Commission did take into account varying penalties linked to different drug quantities (through the assignment scheme described supra at 1385), we conclude that the sentencing ranges resulting in exceptional discrepancies were not adequately considered. See United States v. Ward, 914 F.2d 1340, 1348 (9th Cir.1990) (departure for reasons already considered by the guidelines based on the conclusion that circumstances “significantly more egregious than the ordinary cases” warranting adjustment). Thus the district court was authorized to depart in this case because the de[1388]*1388gree of the discrepancies had not'been adequately considered.
B. Factual Findings
In accordance with Liza-Barraza’s three-part analysis we review the record for factual findings supporting departure. 941 F.2d at 746-47. “The district court may build the appropriate' factual record by adopting a pre-sentence report that has made specific findings of fact that support the decision to depart.” United States v. Singleton, 917 F.2d 411, 412-13 (9th Cir.1990). The district court deemed Reyes a “comparatively minor offender” based on the “minor” nature of both his past and current offenses. The Government has not challenged the quantity-based descriptions of the underlying offenses as clearly erroneous factual findings. Therefore, “[t]he court’s finding that these facts existed obviously met the clearly erroneous standard.” Lira-Barraza, 941 F.2d at 747; see also Valdez-Gonzalez, 957 F.2d at 650 n. 5.
C. Extent
A district court must “give adequate reasons for departure and .for the extent of departure.” United States v. Faulkner, 934 F.2d 190, 191 (9th Cir.1991). The same reason may justify both decisions. See Ramirez Acosta, 895 F.2d at 601-02 (both the reason to depart and extent of departure explained in terms of under-representation of the seriousness of defendant’s criminal history). In explaining the extent of departure, the court may draw analogies to other parts of the guidelines or other offenses. See Lira-Barraza, 941 F.2d at 750-51 & n. 13. “ ‘Reversal is required only if the choice [of a departure sentence] is “unreasonable” in light of the standards and policies incorporated in the Act and the Guidelines.’ ” Martinez-Gonzalez, 962 F.2d at 876 (citing Lira-Barraza, 941 F.2d at 751); see also 18 U.S.C. § 3742(e)(4) (reviewing court must consider whether sentence is “plainly unreasonable.”)
The Government argues that a wholesale departure from the career offender provisions, one that departs from both the criminal history category and the base offense level, constitutes an “unreasonable” departure. It suggests that in the context of Section 4A1.3 a downward departure from the career offender provisions may reasonably consist only of a departure from the criminal history category of a career offender, and not from the base offense level also assigned under these provisions to the career offender. These the Government argues must be retained. Otherwise a sentencing judge can, in the name of downward departure, “completely ignore” the career offender guideline provisions.
When a court determines that the career offender guidelines apply it must take two steps: (1) automatically assign the defendant a criminal history category of VI, and (2) recalculate the base offense level according to the length of the penalty for the conviction. U.S.S.G. 4B1.1. Unlike any other section of the guidelines, the career offender provisions set both sentencing parameters at once. A defendant sentenced under the career offender provisions is subjected to a significant “jump” in penalty precisely because both “steps” — a boost in the criminal history category and a boost in the base offense level — are taken at once.
The Government essentially suggests that the “one-jump-two-steps” application of the career offender guidelines in which both steps are inseparable at the time of application, becomes, for the purposes of departure, a “one-step” modification where one step (criminal history point reduction) is separable from the other (base offense level reduction). It thus advocates understanding career offender departures as consisting only of the criminal history “step.”
The Government’s support for its “one-step” analysis of career offender departures is very limited. It argues that the district court unreasonably departed because it failed to follow the text of Section 4A1.3. Section 4A1.3 has no particularized application to career offender departures. Nowhere does it specify or imply that career offender departures may consist only of downwards adjustments of criminal history categories. Under it “the Court may conclude that the defendant’s criminal history was significantly less serious than that of most defendants in [1389]*1389the same criminal history category” (when deciding whether to depart), “and therefore consider a downward departure from the guidelines,” (how much and for what reason not predetermined). U.S.S.G. § 4A1.3. The provision does suggest that “the court use, as a reference, the guideline range for a defendant with a higher or lower criminal history category,” but does not confine the court to this method of analogizing alone. Id. In the context of a departure from career offender guidelines, it cannot be read to preclude consideration of other analogies or departures from base offense levels.
The district court did not disregard the terms of Section 4A1.3 or go against precedent on departure18 in viewing a departure from the career offender provisions as permissible even though it reduced the sentence more than a modification of only the criminal history category would warrant. Other courts have reasoned:
The jump into the career offender category was made in one [overall increase] under U.S.S.G. § 4B1.1. The district court reversed that single [overall increase] when it reasonably determined ... that placing defendant in the career offender criminal history category significantly over-represented the seriousness of his criminal history.
Bowser, 941 F.2d 1019, 1026 (10th Cir.1991) (district court departed downward to original offense level and criminal history category computed prior to application of career offender provisions). See also, U.S. v. Senior, 935 F.2d 149, 151 (8th Cir.1991) (same). However, in sentencing Reyes to the same punishment he would have received without reference to the career offender guidelines, the court did not provide an explanatory analogy. In different circumstances, we have analogized the career offender provisions to an “on/off switch.” United States v. Faulkner, 934 F.2d 190, 196, as amended, 952 F.2d 1066, 1073 (9th Cir.1991). It may be that like the Bowser and Senior courts and other district courts in the Ninth and Seventh Circuits, the district court, to give proper weight to proportionality, found it necessary in effect to “switch off’ the career offender provisions.19 Because the court failed to articulate its reasons for the degree of its departure, we must remand. Since recidivism is the hallmark of a career offender, the district court may well need to consider the recidivist tendencies of the defendant. An analogy that results in a reduction of both history and base offense level would not be unreasonable.
II. REFUSAL TO CONSENT TO WAIVER
On cross appeal defendant argues that the Court impermissibly allowed the Government to refuse to consent to the defendant’s waiver of jury trial. He contends that the court was obligated to require an explanation from the Government for its refusal so to consent'and to assure that the explanation was not tinged by racial discrimination.
[1390]*1390Although defendant had waived his right to a jury trial, the Government refused to consent to the waiver, and the jury trial commenced. Neither before nor during trial did Reyes argue that the court was obligated to require an explanation for the Government’s refusal to consent to a bench trial.20 Thus, he did not raise this particular issue before the district court.
Ordinarily, an issue raised for the first time on appeal is not considered by this court. United States v. Reyes-Alvarado, 963 F.2d 1184, 1187 (9th Cir.1992); United States v. Carlson, 900 F.2d 1346, 1349 (9th Cir.1990); Jovanovich v. United States, 813 F.2d 1035, 1037 (9th Cir.1987); Bolker v. C.I.R., 760 F.2d 1039, 1042 (9th Cir.1985). However:
We have permitted only narrow and discretionary exceptions to the general rule against considering issues for the first time on appeal. They are (1) when review is necessary to prevent a miscarriage of justice or to preserve the integrity of the judicial process, (2) when a change in law raises a new issue while an appeal is pending, and (3) when the issue is purely one of law.
Jovanovich, 813 F.2d at 1037. Defendant raises an issue which challenges the integrity of the judicial process. We have previously stated that “because a claim that a district court violated a party’s due process rights questions the integrity of the federal judicial system, we review [the defendant’s] claim despite his failure to raise it below.” Prantil v. State of California, 843 F.2d 314, 319 n. 5 (9th Cir.1988). Since this appeal raises primarily a question of law, failure to preserve the legal issue below should not foreclose consideration.
Rule 23(a) of the Federal Rules of Criminal Procedure states that:
[cjases required to be tried by jury shall be so tried unless the defendant waives a jury trial in writing with the approval of the court and the consent of the government.
Fed.R.Crim.P. 23(a) (emphasis added). Though the Government does not have the constitutional right to insist on a jury trial, neither does a defendant have a Sixth Amendment right to waiver. Singer v. United States, 380 U.S. 24, 36-37, 85 S.Ct. 783, 790-91, 13 L.Ed.2d 630 (1965). The Supreme Court has upheld the constitutionality of Rule 23 and specifically considered whether the Government should be forced to provide reasons in exercising its power under it.
Because of [our] confidence in the integrity of the federal prosecutor, Rule 23(a) does not require that the Government articulate its reasons for demanding a jury trial at the time it refuses to consent to a defendant’s proffered waiver. Nor should we assume that federal prosecutors would demand a trial for an ignoble purpose. We need not determine in this case whether there might be circumstances where a defendant’s reasons for wanting to be tried by a judge alone are so compelling that the Government’s insistence on trial by jury would result in the denial to a defendant of an impartial trial.
Singer, 380 U.S. at 37, 85 S.Ct. at 791.
Defendant’s assertion that the requisite “circumstances” were present in his case has no merit. The “passion, prejudice ... and public feeling” defendant feared would jeopardize his right to an impartial trial, Singer at 38, 85 S.Ct. at 791, were specifically addressed and guarded against by the trial judge during voir dire.21
CONCLUSION
We uphold the conviction and hold that the district court may depart from the career offender guidelines for the reason stated. [1391]*1391However, we remand for an explanation of the extent of its departure in light of the considerations set forth in this opinion.
