I. INTRODUCTION
Defendant-appellant Manuel Sierra-Castillo pleaded guilty to illegal reentry following a conviction for a felony in violation of 8 U.S.C. § 1326(a)(l)-(2) and 1326(b)(1). On appeal, he argues that the district court erred in denying him downward departures on grounds of exceptional family circumstances and overrepresentation of criminal history. In supplemental briefing, he further argues that his sentence under the United States Sentencing Guidelines (“U.S.S.G.”) is contrary to the Supreme Court’s holding in
United States v. Blakely,
— U.S. -,
II. BACKGROUND
Sierra-Castillo’s base offense level for illegal reentry following a conviction for a felony was eight. U.S.S.G. § 2L1.2(a) (2002). 1 This offense level was enhanced by sixteen levels pursuant to § 2L1.2(b)(l)(A)(ii) of the Guidelines because of Sierra-Castillo’s prior conviction for attempted sexual assault. It was reduced by three levels for acceptance of responsibility pursuant to § 3El.l(b), resulting in a final offense level of twenty-one. Based on the prior attempted sexual assault conviction and another prior conviction for burglary, Sierra-Castillo’s criminal history category was III. His sentencing range under the Guidelines was therefore forty-six to fifty-seven months.
Sierra-Castillo moved for a downward departure on grounds of exceptional family circumstances, arguing that his common-law wife suffered from breast cancer and that his incarceration would deprive her of needed financial and emotional support during her illness. He also asked for a departure based on overrepresentation of criminal history on the ground that his conviction for attempted sexual assault was nearly fifteen years old at the time of his illegal- reentry.. The district court denied both departures, stating:
[I]t’s difficult for me to see how he has left the heartland ..., and it doesn’t impress me as being aberrant behavior in this case. I’m sympathetic to his wife’s medical condition. Unfortunately, I’m faced with that frequently enough that I’m afraid that likely doesn’t leave the heartland either, in this part of the jurisdiction.
The court sentenced Sierra-Castillo to forty-six months of incarceration, the low end of the Guidelines range.
*936 III. DISCUSSION
A. Downward Departures 2
Sierra-Castillo argues that in considering his motion for downward departures, the district court erroneously defined the heartland as “this part of the jurisdiction” (i.e., the southern part of the District of New Mexico). He cites
United States v. Reyes-Rodriguez
for the proposition that the heartland is instead properly defined with reference to all criminal defendants nationwide.
1. Jurisdiction
Pursuant to 18 U.S.C. § 3742(a), this court has jurisdiction to review a defendant’s appeal of a sentence that was (1) “imposed in violation of law,” (2) “imposed as a result of an incorrect application of the sentencing guidelines,” (3) imposed as a result of the granting of an upward departure, or (4) “imposed for an offense for which there is no sentencing guideline and is plainly unreasonable.”
See United States v. Castillo,
The government argues that this court lacks jurisdiction to review the district court’s denial of Sierra-Castillo’s motion for downward departures because the court did not unambiguously state that it was without authority to depart. The
*937
cases cited by the government, however, hold only that “when a sentence is within the guideline range
and is not imposed in violation of law, or as a result of an incorrect application of the guidelines,
then the district court’s refusal to exercise its discretion to depart downward from the guideline range is not appealable.”
United States v. Davis,
This court has found jurisdiction, for example, over a defendant’s appeal claiming that the district court considered a prohibited factor under the Guidelines in denying a downward departure.
United States v. Guidry,
There are both legal and factual components to a district court’s definition of -the applicable heartland. “Although a district court’s decision to depart usually involves an essentially factual inquiry, in some cases the determination that a defendant falls outside an applicable guideline heartland will not be based primarily on the court’s judgment about the facts of the case, but will involve the court’s determination as to what constitutes a guideline’s heartland.”
United States v. Collins,
This court therefore has jurisdiction to review the question whether the district court committed legal error in this case.
2. Error
This court reviews legal conclusions underlying the district court’s refusal to depart downward
de novo. United States v. Marquez-Gallegos,
3. Harmlessness
In
Williams v. United States,
the Supreme Court held that “once the court of appeals has decided that the district court misapplied the Guidelines, a remand is appropriate unless the reviewing court concludes, on the record as a whole, that the error ... did not affect the district court’s selection of the sentence imposed.”
a. Family Circumstances
Sierra-Castillo’s first proposed ground for a downward departure was that he needed to provide support for his common-law wife, who suffered from breast cancer. The 2002 version of the Guidelines provides that a defendant’s “[f]amily ties and responsibilities ... are not ordinarily relevant in determining whether a sentence should be outside the applicable guideline range.” U.S.S.G. § 5H1.6. Family circumstances are therefore a discouraged ground for departure under the Guidelines.
United States v. Gauvin,
The defendant has the burden of proving entitlement to a downward departure.
United States v. Archuleta,
b. Ove'irepresentation of Criminal History 4
Sierra-Castillo also sought a departure based on the argument that his criminal history category significantly overrepresented the seriousness of his offenses because his prior felony conviction for attempted sexual assault was nearly fifteen
*939
years old at the time he illegally reentered the country. Downward departures under the Guidelines are warranted only when “there exists an aggravating or mitigating circumstance of a kind, or to a degree, not adequately taken into consideration by the Sentencing Commission in formulating the guidelines that should result in a sentence different from that described.” U.S.S.G. § 5K2.0 (quotation omitted).
5
The Guidelines acknowledge that the defendant’s criminal history score is “unlikely to take into account all the variations in the seriousness of criminal history that may occur.” U.S.S.G. § 4A1.3, cmt. background.
6
In contrast to family circumstances, the Guidelines therefore “explicitly encourage a departure when the district court concludes that a defendant’s criminal history category over-represents the seriousness of the defendant’s criminal history.”
Collins,
Although overrepresentation of criminal history is therefore a permissible ground for departure under the Guidelines in some cases, any finding that criminal history is overrepresented must be based on factual circumstances that themselves constitute permissible grounds for departure.
Id.
Whether a factual circumstance is a permissible factor to support a departure is a question of law.
Id.
at 1303. If a particular factor is already fully taken into account by the Guidelines, a downward departure based on that factor is inappropriate.
United States v. Kelly,
The age of a prior conviction, standing alone, is a factor that is already fully accounted for by the Guidelines.
See
§ 4A1.2(e)(l) (providing that certain offenses occurring more than fifteen years prior to commencement of the present offense are not counted in computing a defendant’s criminal history category). Al
*940
though this court in
Collins
did consider the age of a prior conviction as one of several circumstances supporting a departure, the defendant in that case did not base his downward departure argument
solely
on the age of his conviction.
Collins,
c. Combination of Factors
Sierra-Castillo also argued before the district court that he was entitled to a downward departure based on the combination of his family circumstances and criminal history. Combining two invalid departure grounds, however, cannot give rise to a valid ground for departure.
See United States v. Contreras,
B. Booker Error
In supplemental briefing, Sierra-Castillo argues that his sentence under the Guidelines violates the Supreme Court’s holding
*941
in
United States v. Blakely,
— U.S. -,
The only Guidelines enhancement applied to Sierra-Castillo’s sentence was a sixteen-level enhancement based on his prior conviction for attempted sexual assault. As this court noted in
United States v. Gonzalez-Huerta,
a Guidelines enhancement based on the fact of a prior conviction does not implicate the' Sixth Amendment concerns on which the holding in
Booker
was based.
Because Sierra-Castillo did not raise a challenge to the constitutionality of his sentence before the district court, his argument on appeal is subject to review for plain error.
United States v. Cotton,
Gonzalez-Huerta
held that the district court’s error in that case failed to satisfy the fourth plain-error prong.
Gonzalez-Huerta,
Gonzalez-Huerta
establishes the principle that failing to correct non-Sixth Amendment
Booker
error when the defendant has failed to preserve the error in the district court will rarely be found to seriously affected the fairness, integrity, or
*942
public reputation of judicial proceedings.
See id.
at 738-39. Those cases where this court has found the fourth plain-error prong to.be met involved fairness issues not present in this case. In
United States v. Trujillo-Terrazas,
a panel of this court found the test satisfied when an illegal reentry defendant received a sixteen-level enhancement because of a prior conviction for arson.
Trujillo-Terrazas,
Like the defendant in
Trujillo-Terrazas,
Sierra-Castillo received a sixteen-level enhancement based on a prior conviction. Rather than the comparatively innocuous nature of the prior conviction in
Trujillo-Terrazas,
however, Sierra-Castillo’s conviction was for the very serious crime of attempted sexual assault. Although the district judge stated that he was “sympathetic” to Sierra-Castillo’s family circumstances, this comment does not in itself demonstrate that the sentence implicates the kind of fundamental fairness issues necessary to satisfy the fourth plain-error prong. Although the statement might help Sierra-Castillo satisfy the third prong of the plain-error test by showing a reasonable probability that he would have received a lower sentence under an advisory Guidelines system, this court is “bound to treat the third and fourth prongs as independent inquiries.”
Gonzalez-Huerta,
There are no issues comparable to those in Williams and Trujillo-Terrazas that would implicate core notions of justice in this case. Because Sierra-Castillo cannot satisfy the fourth prong of the plain-error test, his sentence must be affirmed.
y. CONCLUSION
Sierra-Castillo’s renewed motion to file a supplemental brief is GRANTED. For the reasons set out above, Sierra-Castillo’s sentence is AFFIRMED.
Notes
. Because Sierra-Castillo was sentenced under the 2002 version of the United -States Sentencing Guidelines, all citations to the Guidelines refer to the 2002 version unless otherwise specified.
. Although the Supreme Court in
United States v. Booker
excised the portion of the Sentencing Reform Act making the Guidelines mandatory, the Court noted that district courts must still "consult [the] Guidelines and take them into account when sentencing."
.
Booker
excised the statutory provision of the Sentencing Reform Act providing for the standard of review of sentences on appeal, 18 U.S.C. § 3742(e), but left intact the section providing for appellate review of sentences, 18 U.S.C. § 3742(a).
See Booker,
. The government argues that the district court's error of limiting the heartland to "this part of the jurisdiction” was limited to the issue of family circumstances and did not infect the court's consideration of a departure based on Sierra-Castillo's criminal history. Although it is unlikely that the district court would have defined the geographic heartland differently in each of the two departure provisions at issue, this court need not definitively decide the issue because the error in any case was harmless.
. The Supreme Court in
Booker
excised the provision of the Sentencing Reform Act providing this standard for departures.
See Booker,
. Despite the placement of § 4A1.3 in chapter four of the Guidelines, this court has held that "departures under section 4A1.3 are not beyond the purview of section 5K2.0.”
United States v. Collins,
. The Guidelines provide for a ten-year limit on prior convictions when the conviction resulted in a sentence of one year and one month or less. U.S.S.G. § 4A1.2(e)(2). Because Sierra-Castillo was sentenced to ten years in prison for attempted sexual assault, the fifteen-year limit instead applies. See § 4A1.2(e)(1).
. If anything, Sierra-Castillo's circumstances counsel
against
a downward departure based on his criminal history category. Section 4A1.3 authorizes departures for overrepresen-tation of criminal history only when "a defendant's criminal history category
significantly
over-represents the seriousness of a defendant’s criminal history.” § 4A1.3 (emphasis added). The Guidelines give as an example of such a case: “a defendant with two minor misdemeanor convictions close to ten years prior to the instant offense and no other evidence of prior criminal behavior in the intervening period.”
Id.
In contrast to the minor crimes given as an example in the Guidelines, Sierra-Castillo was convicted of attempted sexual assault and sentenced to ten years in prison. While he was still on parole for this offense, he then committed a burglary and was sentenced to eight more years of imprisonment.
