       Quincy Blue seeks collateral relief from his criminal sentence. After a federal jury
in Kansas convicted Blue of bank robbery and using a firearm during a crime of
violence, see 18 U.S.C. §§ 924(c), 2113(a), the sentencing court ruled that he was a “career
offender.” For the predicate offenses, the court cited his prior state convictions, which
included two convictions for possessing drugs with intent to sell. He received a


       * We have agreed to decide the case without oral argument because the briefs and
record adequately present the facts and legal arguments, and oral argument would not
significantly aid the court. See FED. R. APP. P. 34(a)(2)(C).
No. 19‐1112                                                                         Page 2

sentence of 30 years’ imprisonment. After a failed appeal and two unsuccessful motions
for collateral relief under 28 U.S.C. § 2255, Blue now seeks relief under 28 U.S.C. § 2241.
He contends that he is entitled to relief under Mathis v. United States, 

(2016), as reflected by a Tenth Circuit decision that he says relied on Mathis to hold that
his drug crimes are not predicate offenses. The district court denied the § 2241 petition.
Because the Tenth Circuit decision relied on pre‐Mathis principles to hold that his drug
crimes are not predicates, Blue could have raised the same arguments in his original
motion under § 2255. He thus cannot use § 2241 to seek relief, so we affirm.

         At the time of Blue’s robbery conviction in 2003, he had four prior Kansas felony
convictions: two for aggravated escape from custody, KAN. STAT. ANN. § 21‐3810 (1993),
one for possessing cocaine with intent to sell

one for possessing
cocaine and marijuana with intent to sell

For career‐offender
status, the Sentencing Guidelines require two prior convictions of either “crimes of
violence” or “controlled substance offenses.” See U.S.S.G. § 4B1.2(b). The probation
office determined that Blue qualified because his two escape convictions were “crimes
of violence.” This subjected Blue to a then‐mandatory Guidelines range of 360 months
to life in prison. Had Blue not been a career‐offender, he would have faced a range of
only 144 to 165 months’ imprisonment. The court imposed the minimum sentence of
360 months. Blue appealed but did not challenge his career‐offender status, and the
Tenth Circuit affirmed. See United States v. Blue, 122 F. App’x 427 (10th Cir. 2005).

        Four years later, Blue filed a counseled motion under 28 U.S.C. § 2255,
contending that he was entitled to resentencing in light of Chambers v. United States,

(2009). Chambers had ruled that a defendant’s Illinois escape conviction did
not count as a “crime of violence,” and Blue argued that the same logic applied to his
Kansas escape convictions. See United States v. Blue, Civ. No. 09‐1108, 

(D. Kan. Aug. 20, 2009). But the court denied his motion, concluding that Blue would
still qualify as a career offender even without the escape convictions because of his two
drug convictions.

convictions under the Kansas drug statute
counted toward career‐offender status and did not appeal.

         In 2016, Blue sought leave to file a successive motion under § 2255(h), relying on
Johnson v. United States, 

(2015), to contest again that his escape
convictions counted toward his career‐offender status. The Tenth Circuit denied leave
to file. It reasoned that because the postconviction court had not relied on Blue’s escape
convictions to deny his § 2255 motion, another case showing that his escape convictions
were not predicates would make no difference.
No. 19‐1112                                                                           Page 3

        Finally, in 2017, Blue filed his current § 2241 petition in the Southern District of
Illinois, where he is incarcerated. This petition attacks the sentencing court’s reliance on
his two drug convictions. Blue contends that under Mathis, and as reflected in United
States v. Madkins, 

(10th Cir. 2017), those convictions are not “controlled
substance offenses.” The district court denied the petition. It explained that Blue could
not file a petition under § 2241 unless he relied on a decision that announced a new rule
of statutory interpretation, which applied retroactively and could not have been
invoked in his earlier petitions. The court concluded that Mathis did not declare a
“new” rule, it merely applied existing precedent.

        Our resolution of Blue’s appeal centers on § 2255(e)’s so‐called “savings clause.”
In general, a federal prisoner wishing to attack his sentence collaterally must file a
§ 2255 motion in the district where he was convicted. Chazen v. Marske, 

, 856
(7th Cir. 2019). But under the savings clause, a prisoner may instead file a § 2241
petition in the district of incarceration if he can show that § 2255 is “inadequate or
ineffective” to test the legality of his detention.

§ 2255 is
“inadequate or ineffective” we apply a three‐part test: the petitioner must show that
(1) he seeks relief based on a decision of statutory interpretation, (2) the decision
declares a rule that applies retroactively and which the prisoner could not have invoked
in his first § 2255 motion, and (3) relief is necessary to avoid a miscarriage of justice.

meet this test, his § 2241 petition must be denied.

to satisfy the second part of our savings‐clause test. Although
the case he relies on, Mathis, 

, is about statutory interpretation, Blue does
not rely on any rule from it that he could not have invoked in his original motion under
§ 2255. To explain this conclusion, we first briefly review how courts determine whether
a state conviction is a predicate offense.

        A defendant’s state conviction qualifies as a predicate offense if the state defines
the offense the same as (or more narrowly than) the Guidelines. United States v. Edwards,

, 835 (7th Cir. 2016). To determine if a state conviction is a match, courts use
the “categorical approach” by “looking only to the statutory definitions of the prior
offenses, and not to the particular facts underlying those convictions.” Taylor v. United
States, 

, 600 (1990). (Cases like Taylor that apply the categorical approach to
the Armed Career Criminal Act are interchangeable with career‐offender Guidelines
cases. See 

n.2). A state conviction is a predicate offense only if
the statutory elements of the offense necessarily encompass all the elements of the
Guidelines definition of the offense.

If a statute is “divisible,” meaning it sets
No. 19‐1112                                                                         Page 4

out one or more elements “in the alternative,” courts use the “modified categorical
approach.” Under this approach, courts may consult jury instructions, indictments, or
plea colloquies to determine under which alternative the defendant was convicted.
Descamps v. United States, 

, 257 (2013). But this approach applies only when
a statute includes alternative elements, not alternative means of satisfying the same
element.

Some circuits (including the Tenth Circuit) did not adhere to this
elements/means distinction and applied the modified categorical approach to any
statute that listed alternative ways of committing a crime, even when it did not include
alternative elements. See 

n.1. So in Mathis, the Supreme Court
reaffirmed the distinction. Specifically, the Court reiterated that (1) the modified
categorical approach applies only when a statute is divisible, and (2) a statute is not
divisible if it merely lists multiple means of satisfying the same element.

        Blue’s petition does not depend on the element/means distinction that Mathis
reaffirmed. Nonetheless Blue believes that he could not have challenged the use of his
drug convictions as predicate offenses before Mathis. For that belief he cites the Tenth
Circuit’s decision in Madkins, which he argues relied on Mathis to hold that Kansas’s
drug crimes of possession with intent to sell are not “controlled substance offenses.” But
in ruling that the Kansas’s definition for “intent to sell” punishes more conduct than its
Guidelines counterpart, Madkins did not rely on anything new in Mathis. It cited Mathis
only for a restatement of pre‐existing law about the categorical approach, not for the
elements/means distinction. 

. Further, in holding that the
Kansas statute was divisible, Madkins applied the same modified categorical approach
that the Tenth Circuit would have used before Mathis.

simply had
not previously considered whether Kansas’s statute matched the Guidelines definition.
See

was new). In short, Mathis did not expand Blue’s opportunity
for relief; he relies on Mathis only for rules of interpretation that were already available
to him when he filed his original petition. See, e.g., 

(describing
modified categorical approach); Shepard v. United States, 

, 26 (2005) (same).

       Similarly, we disagree with Blue’s contention that Mathis and Madkins overruled
other cases in the Tenth Circuit that foreclosed his argument. Blue seizes on a footnote
in Madkins, which he thinks established for the first time that courts should apply the
categorical or modified categorial approach to predicates for career‐offender status
under the Guidelines. 

n.4. But the Tenth Circuit consistently applied
these approaches to career‐offender predicates, well before Madkins and Mathis. See, e.g.,
United States v. Wise, 

, 1144 (10th Cir. 2010); United States v. Charles, 

, 1067 (10th Cir. 2009); United States v. Karam, 

, 1166–67 (10th Cir.
No. 19‐1112                                                                          Page 5

2007). Blue argues that under United States v. Smith, 

(10th Cir. 2006), his
§ 2255 petition was doomed because the Tenth Circuit would have considered his
conduct underlying his drug convictions, rather than just the elements of the offenses.
Yet Smith used the modified categorical approach, just as Madkins did, even if it did not
refer to the doctrine by name. See

(citing Shepard, 

, and 

) (focusing on the elements that defendant was charged with and pleaded
guilty to). Thus Smith did not foreclose Blue from advancing his current arguments.

       Blue next argues that we granted relief to § 2241 petitioners under Mathis in two
cases: Beason v. Marske, 

, 935 (7th Cir. 2019), and Chazen, 

. But
neither case applies here, because, unlike Blue, those petitioners could not raise their
arguments in their § 2255 motions. In Beason, which did not even rely on Mathis, we
noted that the petitioner was previously foreclosed from raising his arguments under
the law‐of‐the‐case doctrine and concluded that intervening circuit precedent entitled
him to 

. And in Chazen, the petitioner could not obtain relief in his
original § 2255 motion in Minnesota because binding Eighth Circuit precedent, which
Mathis abrogated, held that his prior conviction for Minnesota burglary counted as a
predicate offense under the Armed Career Criminal Act. 

.

       Blue makes two additional arguments in favor of granting relief, but neither has
merit. First, he accuses the district judge who denied his § 2241 petition of improper ex
parte communications with the government. Blue points out that when the government
moved for an extension of time to respond to his petition, the Assistant United States
Attorney asked the court’s staff whether she should file a consolidated answer to Blue’s
petition and amended petition. But ex parte communications are permitted “for
scheduling, administrative, or emergency purposes” as long as they do “not address
substantive matters and the judge reasonably believes that no party will gain a
procedural, substantive, or tactical advantage as a result.” CODE OF CONDUCT FOR U.S.
JUDGES Canon 3(A)(4)(b); see also Drobny v. Comm’r, 

, 680 (7th Cir. 1997).
Because Blue cites no evidence of other communications between the government and
the court, nor evidence that this contact prejudiced him or involved the merits, the court
did not abuse its discretion by allowing its staff to answer it.

       Second, Blue argues that denying him relief violates his right to equal protection
in two ways: (1) a different judge granted collateral relief to a different petitioner based
on what Blue argues were similar grounds, and (2) the government conceded issues in
that case that it refuses to concede here. The first argument fails because, among other
defects, nothing suggests that either decision was based on intentional discrimination, a
No. 19‐1112                                                                         Page 6

predicate of an equal‐protection violation. Washington v. Davis, 

(1976).
Similarly, on the second point, Blue cannot challenge the government’s prosecutorial
decisions because he lacks evidence of discrimination based upon invidious criteria
such as race or religion. See United States v. Moore, 

, 900 (7th Cir. 2008).
