I. INTRODUCTION
Juan Cruz Vega was convicted in Colorado state court on charges of possessing more than twenty-eight grams of cocaine with intent to distribute. See Colo.Rev. Stat. §§ 18-18-105(1), (3) (1991). Although the presumptive sentencing range 1 for a conviction on such charges was from four to sixteen years, 2 Vega was sentenced to a term of imprisonment of twenty-four years and one day because he was found to be a “special offender.” 3 Vega was adjudged a special offender because he had “introduced, distributed, or imported” the cocaine “into the state of Colorado.” Colo. Rev.Stat. § 18-18-107(l)(d) (1991). 4
On direct appeal, Vega argued as follows: (1) he was denied due process of law and thе right to a trial by jury because the trial court refused to allow him to raise an entrapment defense to the special-offender charge; and (2) he was denied his Sixth Amendment right to confront the witnesses against him because the trial court had excluded evidence of internal Drug Enforcement Agency incentives for the conviction of drug offenders. The Colorado Court of Appeals and Colorado Supreme Court, in turn, rejected Vega’s contentions and affirmed his conviction and sentence.
See People v. Vega,
After his conviction and sentence were affirmed on direct appeal, Vega filed the instant § 2254 habeas corpus petition. In the petition, Vega raised the same two claims he raised on direct appeal. The district court concluded that Vega was not entitled to habeas relief for substantially those reasons stated by the Colorado Supreme Court on direct appeal and, therefore, dismissed Vega’s petition with prejudice. Exercising jurisdiction pursuant to 28 U.S.C. § 2253, 5 this court affirms.
*577 II. BACKGROUND
A. Factual Background
The prosecution of Vega grew out of a sting operation that began with the arrest of John Anderson in Colorado on arson and burglary charges. Anderson, who also had drug charges pending against him in Nevada, approached law enforcement officials in Colorado in hopes of providing information in exchange for a reduction of the charges against him and for lеniency in sentencing.
Anderson convinced agents of the Drug Enforcement Administration (“DEA”) and the Arvada, Colorado Police Department (“APD”) to allow him to negotiate with individuals who might import narcotics into Colorado. Anderson began his work with the DEA and APD by calling Charlie Aponte, an individual Anderson had known for some period of time. Anderson called Aponte in California and indicated that he “was in Colorado and had a buyer” and that he “would like to do some business.” Aponte indicated that he would “look into it.” Although Anderson made several additional calls from November of 1990 through January of 1991, the telephone negotiations did not come to fruition. Nevertheless, Anderson was released from custоdy in Colorado so that he could travel to California in the hope of consummating a sale and delivery of drugs to Colorado. Anderson remained in California for a number of weeks to continue negotiations with Aponte. Aponte eventually agreed to provide Anderson with drugs during one of their meetings.
At some point, Vega, a friend of Aponte, became involved in the conspiracy to deliver drugs to Colorado. On the evening of January 14, 1991, after the deal had been finalized, Anderson, Aponte, Vega, and an additional co-conspirator flew to Denver with three kilograms of cocaine. Upon arrival in Denver, undercover DEA agents met the group at the airport and trаnsported them to a hotel where the deal was to be consummated. The DEA agents videotaped the transaction at the hotel and then arrested Vega and the others.
Vega was charged with possession of cocaine with intent to distribute in violation of Colo.Rev.Stat. § 18-18-105 (1991) and as a special offender pursuant to Colo. Rev.Stat. § 18-18-107 (1991) because he had imported the cocaine into Colorado. At trial, Vega asserted entrapment as an affirmative defense 6 to both the possession-with-intent-to-distribute and special-offender charges. The trial court, however, refused to instruct the jury that the entrapment defense applied to the special-offender charge. It reasoned that the special-offender statute did not define a substantive offense, but rather was a sentence enhancement provision to which affirmative defenses did not apply. The trial court also excluded, as irrelevant, proffered cross-examination questions concerning internal DEA incentives to promote the arrest and conviction of drug traffickers.
The jury found Vega guilty of distribution of cocaine and returned a special verdict finding beyond a reasonable doubt that Vega had imported the cocaine into *578 Colorado. Based on the special verdict, the trial court found that Vega was a special offender subject tо enhanced sentencing under Colo.Rev.Stat. § 18-18-107 (1991) and imposed a sentence of twenty-four years and one day.
B. Procedural History
1. Colorado State Court Proceedings
Vega appealed his conviction to the Colorado Court of Appeals (“CCA”), which affirmed.
See People v. Vega,
As to Vega’s claim that the proposed cross-examination was relevant to demonstrate bias in the DEA agents’ testimony, the CSC exercised its prerogative to ignore Vega’s procedural default and reviewed the issue on the merits.
Id.
That review led the CSC to conclude the trial court had erred in precluding the proposed cross-examination because the “testimony would have revealed the specific benefits that would accrue to the agents should Vega be convicted of the charges against him and would have demonstrated the DEA agents’ ‘motive[s] for favoring the prosecution’ and strong interest in the outcome.”
Id.
at 120 (quoting
Delaware v. Van Arsdall,
The CSC also rejected Vega’s claim that denying him an opportunity to present an entrapment defense to the special offender charge violated the Due Process Clause.
Id.
at 113-17. The CSC began its analysis of this issue by considering “the language of the statute, its legislative history, and the criteria [the CSC had] applied in the past to distinguish substantive offenses from sentencing provisions” and concluding, purely as a matter of state law, that § 18-18-107 is a “sentencing provision to which affirmative defenses do not apply.”
Vega,
In analyzing that question, the CSC looked to the Supreme Court’s decision in
McMillan v. Pennsylvania,
2. Section 2251 Habeas Corpus Proceedings
After Vega had exhausted his direct appeals in state сourt, he filed the instant § 2254 habeas corpus petition. In his petition, Vega once again raised the claims relating to the special-offender statute and the limitation on his cross-examination of the DEA agents. The matter was referred to a magistrate for initial proceedings pursuant to 28 U.S.C. § 636(b)(1). The magistrate recommended that the writ be granted in an extensive Report and Recommendation (“R & R”). According to the magistrate, “[t]he net result is that [Vega] received more than a mere sentence enhancement. He was convicted of an upgraded felony on a factual issue where the burden of proof was lessened. The Colorado General Assembly has transformed a sentencing factor into an element of an offense [in violation of the Supreme Court’s decision in
McMillan].”
As to Vega’s claim relating to limitation on his cross-examination of the DEA agents, the magistrate concluded, after a thorough review of the trial record and opinion of the CSC, that the limitation was harmless because “[t]here is no indication that the excluded information would have made any substantial difference in the outcome of the case.”
Cf. Brecht v. Abrahamson,
The respondents filed a timely objection to the magistrate judge’s R & R, asserting the magistrate had erred in concluding thаt treating § 18-18-107 as a sentencing provision violated Vega’s right to due process. Upon de novo, review, the district court rejected the magistrate’s recommendation as to the sentence enhancement for substantially those reasons stated by the CSC in its opinion on direct appeal. Furthermore, despite Vega’s failure to object, the district court reviewed de novo that portion of the R & R analyzing Vega’s cross-examination claim and agreed the erroneous limits imposed by the trial court were harmless.
III. ANALYSIS
A. Limitation on Cross-Examination of DEA Agents
Vega asserts the district court erred in concluding that the limitations imposed by the state trial court on Vega’s cross-examination of the DEA agents did not have a substantial and injurious effect on the outcоme of the trial. We conclude that Vega waived appellate review of this question when he failed to file an objection to the magistrate’s R & R.
This court has adopted a “firm waiver rule” which provides that a litigant’s failure to file timely objections to a magistrate’s R & R waives appellate review of both factual and legal determinations.
See United States v. One Parcel of Real Property,
In the alternative, Vega asserts this court should reach the merits of his cross-examination claim because the “ends of justice” so dictate.
See Talley v. Hesse,
B. Denial of Entrapment Defense to Special Offender Charge
1. Standard of Review
This court “review[s] the district court’s legal conclusions
de novo[
] and its factual findings for clear error.”
See Hawkins v. Hannigan,
2. Analysis
The parties to this appeal offer the court two diametrically opposed modes of analysis for resolving Vega’s claims. Vega states the issue on appeal in the following broad and abstract terms: Can Colorado, consistent with the Due Process Clause, treat § 18-18-107 as a sentencing provi *581 sion rather than as a separate substantive crime or an element of the underlying possession-with-intent-to-distribute offense? So stated, Vega asserts that the question can only be resolved by reference to the Supreme Court’s McMillan line of cases. 8 As noted above, the CSC, magistrate judge, and district court all accepted Vega’s assertion that the McMillan line controlled the disposition of his claims, although not all agreed that those cases entitled him to relief. See supra Section 11(B) (setting forth opinions of each).
Although the respondents appear to have acquiesced in the applicability of the
McMillan
line before the CSC and the district court, they argue on appeal that when viewed with an appropriate level of specificity, Vega’s claims regarding the special-offender provision do not implicate the
McMillan
line at all. In particular, the respondents note that the cases in the
McMillan
line all involve, to one degree or another, the question of whether a sovereign can evade the high level of proof constitutionally required to establish criminal offenses by restructuring some essential elements of the crime into sentencing, factors.
9
In this case, however, it is undisputеd that Vega received all of the procedural protections at issue in the
McMillan
line: (1) he was provided notice of the possibility of the special-offender enhancement through a separate pre-trial charge; (2) the question of whether he had imported the cocaine into Colorado was submitted to the jury in a special verdict form; and (3) the jury was instructed that it must find the element of importation “beyond a reasonable doubt.”
See Vega,
This court agrees with respondents that Vega’s proposed analytical model constitutes a semantic wordplay which exalts form over substance. Ultimately, it matters not-at-all what terminology Colorado chose to apply to § 18-18-107, be it “sentence enhаncement,” “crime,” or “element,” if that semantic choice has no impact on the procedural protections due a criminal defendant. In this case, Colorado’s decision to label § 18-18-107 as a sentencing enhancement did not free the state prosecutor from the burden of providing proper notice of the applicability of the enhancement through a separate pretrial charge, remove the determination of the existence of the operative fact of importation from the jury, or reduce the prosecutor’s burden of proving the fact of importation beyond a reasonable doubt.
See Vega,
*583
As to this very narrow question, we conclude that Colorado can, consistent with due process, choose not to make the affirmative defense of entrapment available to a charge of importation of cocaine in violation of § 18-18-107.
13
The Supreme Court has long recognized that the defense of entrapment “is not of a constitutional dimension.”
United States v. Russell,
Based on
Russell, Hampton,
and those additional authorities cited above, we conclude that Colorado can, consistent with the Due Process Clause, preclude the applicability of an entrapment defense to Colorado’s special-offender statute.
Cf. Bueno v. Hallahan,
IV. CONCLUSION
For those reasons set out above, the order of the United States District Court for the District of Colorado denying Vega’s § 2254 habeas petition is hereby AFFIRMED.
Notes
. At the time of Vega's conviction, Colorado divided felonies into six classes and provided a presumptive minimum and maximum sentence for each of the six classes. See Colo. Rev.Stat. § 18-l-105(l)(a)(IV) (1991). Absent a finding by the trial court of one or more non-delineated aggravating or mitigating factоrs or one or more specifically delineated aggravating factors, the trial court is required to sentence a felon to a determinate sentence within the presumptive range. See id. §§ 18 — 1—105(l)(b)(I), (6), (9) (1991).
. See Colo.Rev.Stat. § 18-18-105(2)(a) (1991) (classifying offense of possessing cocaine with intent to distribute, absent a prior conviction, as a class 3 felony); id. § 18-l-105(l)(a)(IV) (1991) (providing a presumptive sentencing range of 4 to 16 years for a class 3 felony).
.
See
Colo.Rev.Stat. § 18-18-107 (1991) (providing that upon a felony conviction and the finding of one or more of the specifically-delineated “extraordinary aggravating circumstances,” the defendant is classified as a "special offender” and the court is required to "sentence the defendant to a term greater than the presumptive range for a class 2 felony but not more than twice the maximum term for a class 2 felony”);
id.
§ 18 — 1— 105(l)(a)(IV) (1991) (providing a presumptive sentence range of 8 to 24 years for a class 2 felony). Read together, these two provisions create a minimum sentence for a special offender of twenty-four years and one day and a maximum sentence of forty-eight years.
See Vega v. People,
. Section 18-18-107(l)(d), the provision at the heart of this case, provides as follows:
(1) Upon a felony conviction ... under this article, the presence of any one or more of the following extraordinary aggravating circumstances designating the defendant a sрecial offender shall require the court to sentence the defendant to a term greater than the presumptive range for a class 2 felony but not more than twice the maximum term for a class 2 felony authorized in the presumptive range for the punishment of such felony:
(d) The defendant unlawfully introduced, distributed, or imported into the state of Colorado any schedule I or II controlled substance....
Colo.Rev.Stat. § 18-18-107(l)(d) (1991).
. Vega filed his § 2254 habeas petition on October 25, 1995, well before the April 24, 1996 effective date of the Antiterrorism and Effective Death Penalty Act of 1996 ("AED-PA”), Pub.L. No. 104-132, 110 Stat. 1214. Accordingly, the AEDPA’s revised standards
*577
of review and certificate-of-appealability requirements do not apply.
See Lindh v. Murphy,
. See Colo.Rev.Stat. § 18-1-709 ("The commission of acts which would otherwise constitute an offense is not criminal if the defendant engaged in the proscribed conduct because he was induced to do so by a law enforcement official ....”); see also id. § 18-1-710 (providing that the exemption from criminal liability set out in § 18-1-709 is an affirmative defense).
. This court has, in a case involving a
pro se
litigant, reviewеd the merits of the omitted issues, as one factor among many, in deciding whether to apply the "ends of justice" exception.
See Theede v. United States,
. For purposes of this opinion, all of the following cases fall within the
McMillan
line:
In re Winship,
.
See Winship,
.Several cases in the
McMillan
line make clear that these three core protections are at the heart of the ability of the government to define an operative fact as a sentencing factor rather than an element of the underlying crime or separate substantive offense.
See
*582
Jones, 119 S.Ct. al 1228 (holding that federal carjacking statute creates three separate offenses, rather than one offense and two sentencing provisions, "each of which must be charged by indictment, proven beyond a reasonable doubt, and submitted to the jury for its verdict”);
Id.
at 1228-29 (Stevens, J., concurring) ("I am convinced that it is unconstitutional for a legislature to remove from the jury the assessment of facts that increase the prescribed range of penalties to which a criminal defendant is exposed. It is equally clear that such facts must be established by proof beyond a reasonable doubt. That is the essence of the Court's holdings in
[Winship, Mullaney,
and
Patterson].")', Almendarez-Torres,
. According to respondents, Vega is procedurally barred from raising this narrow ques
tion
— i.e., whether the Due Process Clause mandates that states make an entrapment defense available — because he failed to litigate the issue in state court.
See Coleman v. Thompson,
Whether the [CCA's] holding, that an accused is not entitled to present the affirmative defense of entrapment, or any affirmative defense to a charge of importation of a controlled substance under the special offender statute, § 18-18-10 7, 8B C.R.S. (1986), violates federal and state constitutional guarantees to due process of law.
Vega,
. This court recognizes that in some cases the question of whether a provision of law creates a sentencing enhancement or substan
*583
tive offense will implicate the Due Process Clause.
See, e.g., Jones,
. Vega has not asserted at any point in these proceedings, including on direct appeal, that Colorado's choice to make available the affirmative defense of entrapment to some offenses while precluding its application to § 18-18-107 violates the Equal Protection Clause. This court offers no opinion on that question.
.
See also United States v. Spivey,
.It is important to once again emphasize the narrow focus of Vega's § 2254 habeas claims. Vega has always focused on the narrow question of whether Colorado could deny him the entrapment defense set out in Colo. Rev.Stat. § 18-1-709 (1991) through the artifice of labeling § 18-18-107 a sentencing provision rather than a separate, substantive crime. If Colorado’s entrapment defense was available, Vega’s predisposition to commit the crime would become an element of the offense which the prosecution would have to prove beyond a reasonable doubt.
See Vega,
.
See Johns v. McFadden,
No. 93-15844,
. Does a habeas petitioner state a cognizable due process claim when state law makes the question of entrapment an element of the underlying offense, which must be disproved by the prosecution beyond a reasonable doubt, and the petitioner alleges that the state court erroneously refused to instruct on a factually supported entrapment defense? That fact pattern presents a markedly different question than the one presented in this case because Colorado has simply chosen not to malte any entrapment defense available to special-offender charges.
