          APPEALS FROM THE UNITED STATES DISTRICT COURT
                    FOR THE DISTRICT OF MAINE

          [Hon. George Z. Singal, U.S. District Judge,
           Hon. D. Brock Hornby, U.S. District Judge]


                             Before

                      Howard, Chief Judge,
              Torruella and Lynch, Circuit Judges.


     David Beneman, Federal Public Defender, for appellants.
     Julia M. Lipez, Assistant United States Attorney, with whom
Richard W. Murphy, Acting United States Attorney, was on brief,
for appellee.


                        February 2, 2018
          LYNCH, Circuit Judge.        This consolidated appeal arises

from the denials of three federal post-conviction relief petitions

filed under 28 U.S.C. § 2255.    Richard Dimott, Wayne N. Collamore,

and Charles H. Casey, Jr., each pled guilty to a federal firearm

offense and had a history of Maine state burglary convictions.        On

collateral review, all three allege that they no longer qualify

for a sentence enhancement under the Armed Career Criminal Act

("ACCA") because the ACCA's residual clause was invalidated by

Johnson v. United States, 135 S. Ct. 2251 (2015) ("Johnson II").

          Each    petitioner   filed    his   federal   habeas   petition

outside of the one-year statute of limitations under 28 U.S.C.

§ 2255(f)(1).    All three nevertheless contend on appeal that their

petitions are timely under 28 U.S.C. § 2255(f)(3) because Johnson

II, which is retroactively applicable, is the source of their

claims.   Specifically, Dimott, Collamore, and Casey argue that

they were sentenced pursuant to the ACCA's (now-void) residual

clause, so their sentences must be vacated, and they cannot be

resentenced under the ACCA's enumerated clause in light of Mathis

v. United States, 136 S. Ct. 2243 (2016),1 a case that is not

retroactively applicable.

          The district courts in all three cases dismissed the

petitions on procedural grounds.       We affirm the dismissals.     All


     1    More specifically, the petitioners argue that Mathis
requires that we overrule this court's holding in United States v.


                                 - 2 -
three petitions are untimely because they raise Mathis, not Johnson

II claims, and Mathis does not reset the one-year statute of

limitations under § 2255(f)(3).    The petitioners have no Johnson

II claims because they have not shown that their original ACCA

sentences were based solely on the residual clause.

                                  I.

            We first determine, as to each petitioner, whether the

district court sentenced him pursuant to the enumerated or (the

separate) residual clause of the ACCA.     Accordingly, we give the

relevant procedural history of each case.

A.     Dimott

            Richard Dimott pled guilty to one count of being a felon

in possession of a firearm on March 30, 2007, in violation of 18

U.S.C. §§ 922(g)(1) and 942(e).    Based on his eight previous state

convictions in Maine for burglary, see Me. Rev. Stat. Ann. tit.

17-A, § 401, the district court concluded that Dimott qualified

for the sentencing enhancement under the ACCA, but did not specify

under which clause -- enumerated or residual -- it was sentencing

him.    On September 6, 2007, the district judge sentenced Dimott

to 150 months of imprisonment and five years of supervised release.

Dimott did not appeal his sentence.



Duquette, 778 F.3d 314, 317 (1st Cir. 2015), that a Maine burglary
conviction is a violent felony under the enumerated clause, 18
U.S.C. § 924(e).


                                - 3 -
          About nine years after his conviction, Dimott filed a

motion to correct his sentence under 28 U.S.C. § 2255 on June 27,

2016.   This was within one year of the Supreme Court's decision

in Johnson II.    Dimott argued that his convictions for Maine

burglary cannot be the basis for his ACCA sentence because the

Supreme Court's 2016 decision in Mathis made clear that Maine

burglary is nongeneric and thus did not fall under the enumerated

clause, and Johnson II invalidated sentences that were based on

the ACCA's residual clause.

          The district court denied Dimott's habeas petition for

being untimely.   The same judge who had sentenced Dimott earlier

under the ACCA, rejected the petition:

          Johnson II is understood to be one such
          decision newly recognizing a right that is
          retroactively   applicable . . . .    However,
          Dimott was deemed eligible for an ACCA
          sentence based only on burglary convictions,
          which   qualify   under   ACCA's   "enumerated
          clause." . . . Dimott's reliance on Mathis
          is also misplaced. In contrast to Johnson II,
          Mathis has not been recognized as a case that
          announced a new substantive rule that is
          retroactively    applicable   to    cases   on
          collateral review.

6068114, at *2-3 (D. Me. Oct. 14, 2016) (emphasis added).     The

district court issued Dimott a certificate of appealability, and

he filed this appeal on October 21, 2016.




                              - 4 -
B.     Collamore

              Wayne N. Collamore pled guilty on December 21, 2010, to

one count of escape from the custody of the United States Bureau

of Prisons, in violation of 18 U.S.C. § 751(a), and one count of

being a felon in possession of a firearm.                        Based on, inter alia,

his    five   previous       state        convictions      for    Maine    burglary,    the

district court found Collamore to be an armed career criminal,

again without specifying under which clause of the ACCA.                         On March

23, 2011, the sentencing judge imposed five years of imprisonment

for the escape count, and a concurrent 210 months of imprisonment

--    based   on     the    ACCA    enhancement       --    for    the    firearm    count.

Collamore did not appeal his sentence.

              More     than        five     years    after        his     conviction     and

sentencing, Collamore filed a § 2255 motion on May 19, 2016,

arguing that his ACCA predicates were invalid post-Mathis.                              The

reviewing judge, who was also Collamore's sentencing judge, denied

Collamore's        habeas     petition       for    being    untimely.        That     judge

specifically cited the Dimott decision to explain the dismissal:

              This Court has recently had occasion to
              consider whether Mathis triggered a new one-
              year period for habeas relief under 28 U.S.C.
              § 2553(f)(3).      In  Dimott,   this   Court
              concluded that it did not. This Court also
              concluded that Johnson II does not provide a
              basis to challenge the status of convictions
              that were deemed to fall within ACCA's
              enumerated clause, as opposed to the now-
              invalidated residual clause.

Collamore v. United States, Nos. 2:16-cv-259, 2:10-cr-158, 2016 WL

6304668, at *2 (D. Me. Oct. 27, 2016) (internal citations omitted).

The district court issued a certificate of appealability, and this

appeal was docketed on October 31, 2016.

C.      Casey

                Charles H. Casey, Jr., pled guilty to being a felon in

possession of a firearm on April 27, 2012.                     The district court

found that Casey qualified for an ACCA sentencing enhancement based

on, inter alia, his three prior convictions in Maine for burglary,

without specifying which ACCA clause was involved, and sentenced

Casey to 180 months of imprisonment.                   Casey did not appeal his

sentence.

                Nearly four years after his conviction and sentencing,

Casey    filed     a   § 2255   motion   on     June    27,   2016,   collaterally

attacking his sentence.          The same judge who had sentenced Casey,

heard    the     petition.      Casey    argued    that       his   Maine   burglary

convictions did not constitute predicate offenses under the ACCA.

The Government responded that Casey's petition was barred because

his Johnson II claim was procedurally defaulted.                      The district

court agreed with the Government and found that Casey failed to

demonstrate that his procedural default would unfairly prejudice

him "[b]ecause extant First Circuit caselaw holds that Casey's

prior Maine burglary convictions remain qualifying enumerated




                                        - 6 -
violent felonies even after Johnson's invalidation of the residual

clause."

           Although the Government did not raise -- and the district

court did not address -- either the timeliness issue or the merits

of whether the Maine burglary statute was generic, the certificate

of appealability, requested by Casey, touched indirectly on both:

           Casey's petition raises the following issues:
           (1) whether the retroactive application of
           Johnson allows any petitioner serving an ACCA
           sentence to have his qualifying "violent
           felony" convictions re-examined even if those
           convictions appear to fall under the ACCA's
           enumerated clause; and (2) if so, whether
           Mathis has effectively overruled the First
           Circuit's    decision . . . that    a    Maine
           burglary   conviction . . . qualifies   as   a
           violent felony under ACCA's enumerated clause.

Casey timely filed this appeal.

                                  II.

           Dimott, Collamore, and Casey argue on appeal that the

district courts erred in denying their petitions because they were

sentenced pursuant to the ACCA's (now-void) residual clause.       We

review de novo the district courts' denials of their habeas

petitions on procedural grounds.        See Wood v. Spencer, 487 F.3d

1, 3 (1st Cir. 2007) (citing Rodriguez v. Spencer, 412 F.3d 29, 32

(1st Cir. 2005)).     Because we find all three petitions time-

barred, we do not reach the merits of the petitioners' argument

that their predicate offenses no longer qualify under the ACCA



                               - 7 -
because Johnson II voids the residual clause and Mathis renders

Maine burglary a nongeneric offense that does not qualify under

the enumerated clause.

          Congress enacted the Antiterrorism and Effective Death

Penalty Act (AEDPA) "in part to combat increasingly pervasive

abuses of the federal courts' habeas jurisdiction."      Delaney v.

Matesanz, 264 F.3d 7, 10 (1st Cir. 2001) (citing Felker v. Turpin,

518 U.S. 651, 664 (1996)).   The statute imposes a one-year statute

of limitations on federal prisoners for filing habeas petitions,

which runs from the latest of "(1) the date on which the judgment

of conviction bec[ame] final; . . . [or] (3) the date on which the

right asserted was initially recognized by the Supreme Court, if

that right has been newly recognized by the Supreme Court and made

retroactively applicable to cases on collateral review."          28

U.S.C. § 2255(f).

          More than one year had passed between the time each

petitioner's conviction became final and the date on which each

petitioner filed his § 2255 motion.     As such, for their petitions

to be timely, Dimott, Collamore, and Casey must demonstrate that

(1) their claims arise from a right that "has been newly recognized

by the Supreme Court and made retroactively applicable," and that

(2) they filed within one year of the Supreme Court's decision

recognizing that right.   Id.   Each petitioner argues that Johnson

II -- which the Supreme Court held is retroactively applicable on


                                - 8 -
collateral review, see Welch v. United States, 136 S. Ct. 1257,

1268 (2016) -- is the basis of his claim, and that his petition is

timely.   We disagree and find all three petitions untimely because

they raise Mathis, not Johnson II, challenges, and, in any event,

the petitioners have no Johnson II claims.    We first address the

petitions of Dimott and Collamore, before turning to Casey.

A.   Dimott and Collamore

           We find it plain that Dimott's and Collamore's petitions

do not raise Johnson II challenges because the record reflects

that they were sentenced under the ACCA's enumerated clause, not

the residual clause.   As such, we need not delve into the merits

because their petitions, at most, raise untimely Mathis claims.

           On collateral review, the district court judge in both

cases (who had also served as the sentencing judge) found that

Dimott and Collamore had earlier been sentenced pursuant to the

ACCA's enumerated clause.   See Collamore, 2016 WL 6304668, at *2

("Johnson II does not provide a basis to challenge the status of

[Collamore's] convictions that were deemed to fall within ACCA's

enumerated clause, as opposed to the now-invalidated residual

clause."); Dimott, 2016 WL 6068114, at *2 ("Dimott was deemed

eligible for an ACCA sentence based only on burglary convictions,

which qualify under ACCA's 'enumerated clause.'").

           Although these findings were made during the collateral

review process, and not expressly stated at the time of sentencing,


                               - 9 -
we give them due weight because the habeas judge was describing

his own decisions at sentencing.                 Cf. United States v. DiCarlo,

575 F.2d 952, 954 (1st Cir. 1978) (holding that "if the [post-

conviction relief] claim is based upon facts with which the trial

court, through review of the record or observation at trial, is

familiar,    the    court      may    make    findings     without    an   additional

hearing"); see also United States v. Snyder, 871 F.3d 1122, 1128

(10th Cir. 2017) (giving due weight to the district court's

determination that "as a matter of historical fact, . . . it did

not apply the ACCA's residual clause in sentencing [the defendant]

under ACCA"); Feldman v. Perrill, 902 F.2d 1445, 1447 (9th Cir.

1990) (crediting the district court's determination that "he had

not relied on the 1976 conviction, only the underlying conduct,"

when the petitioner "initiated an attack on his federal sentence,

arguing that it had been improperly enhanced due to the sentencing

judge's    reliance       on   an    allegedly      invalid   state    conviction").

Here, too, there is no gap in information about what happened.

And the petitioners do not contend that the district court was

incorrect in its characterization.

            Because       they      were   sentenced     pursuant     to   the   ACCA's

enumerated clause, Dimott and Collamore are, at most, asserting a

claim about Mathis.            In fact, the linchpin of both petitioners'

argument    is     that    Mathis      dictates     that   Maine     burglary     is   a

nongeneric offense, so it cannot qualify as an ACCA predicate.


                                           - 10 -
The Supreme Court has indicated, though, that Mathis did not

announce a new, retroactively applicable rule.         See 136 S. Ct. at

2257 (noting that the case was a "straightforward" application of

more than "25 years" of precedent).          Thus, the precondition for

the timeliness requirement under § 2255(f)(3) is not met.             Cf.

Stanley v. United States, 827 F.3d 562, 565 (7th Cir. 2016)

("Johnson does not have anything to do with the . . . elements

clause of . . . the Armed Career Criminal Act, and § 2255(f)(3)

therefore does not afford prisoners a new one-year period to seek

collateral relief on a theory that the elements clause does not

apply to a particular conviction.").

           To circumvent the statute of limitations, Dimott and

Collamore try to pass off their Mathis claims under the guise of

Johnson II claims, but their argument is foiled by a logical

misstep.   In order to even arguably invoke Johnson II, they must

first succeed in arguing -- on the merits -- that their ACCA

enhancement relies on the residual clause because Mathis renders

Maine burglary a nongeneric offense.          That is the essence of a

Mathis challenge.    To hold otherwise would create an end run around

AEDPA's statute of limitations.         It would allow petitioners to

clear the timeliness bar by bootstrapping their Mathis claims onto

Johnson II claims, even where, as here, the merits of their case

entirely   depend   on   whether   their    previous   convictions   still

qualify as ACCA predicates in light of Mathis.            This cannot be


                                   - 11 -
right.    The district court correctly concluded that Dimott's and

Collamore's petitions depended on Mathis, and were thus untimely.

B.   Casey

             The remaining petitioner, Casey, presents a somewhat

different case because (1) the Government failed to assert the

timeliness defense before the district court, and (2) the record

is silent as to which ACCA clause -- enumerated or residual -- the

district court earlier relied on.        Regardless, Casey's petition

is time-barred for the same reason as the other two petitions: it

raises a Mathis, not a Johnson II, challenge.

     1.      Forfeiture

             The Government failed to argue before the district court

that Casey's petition was untimely, relying instead on another

procedural bar: that Casey had defaulted his Johnson II claim.     On

appeal, Casey attempts to use the Government's omission as a shield

against AEDPA's strict statute of limitations and argues that the

government may no longer raise the timeliness issue on appeal.

             We disagree that the Government's inadvertence is fatal

to applying the timeliness bar here.          The Supreme Court has

repeatedly recognized the power of federal courts to raise sua

sponte the timeliness of habeas petitions.       See Wood v. Milyard,




                                - 12 -
566 U.S. 463, 473 (2012) (courts of appeals); Day v. McDonough,

547 U.S. 198, 209 (2006) (district courts).2

                  The dissent asserts that appellate courts may excuse the

Government's waiver only if the Government proves that the case is

"exceptional." But that is a misreading of Wood.3                    There, the

Supreme Court reaffirmed the general principle that "court[s] may

consider a statute of limitations or other threshold bar the State

failed to raise in answering a habeas petition," 566 U.S. at 466

(citations omitted), and only cautioned against doing so if "the

State, after expressing its clear and accurate understanding of

the timeliness issue, deliberately steer[s] the District Court

away       from    the   question   and   towards   the   merits,"   id.   at   474

(citations omitted).          The Court narrowly held in Wood that it was



       2  Both Day and Wood concerned federal habeas petitions
brought by state prisoners under 28 U.S.C. § 2254, not by federal
prisoners under § 2255.     We see no reason, however, why this
Court's power to raise sua sponte the timeliness defense for § 2254
cases should not extend to § 2255 cases.           The statute of
limitations provisions of both statutes mirror one another, and
the considerations flagged by the Supreme Court in Day -- "judicial
efficiency," "conservation of judicial resources," and "finality,"
547 U.S. at 205-06 (quoting Acosta v. Artuz, 221 F.3d 117, 123 (2d
Cir. 2000)) -- apply equally in the context of federal prisoners
seeking post-conviction relief.
       3  In any case, the Supreme Court found in Day, the
predecessor to Wood, that inadvertent error can constitute an
"extraordinary   circumstance[]"   that  justifies   raising   the
timeliness bar sua sponte. See Wood, 566 U.S. at 471 (citing Day,
547 U.S. at 201, 203). In Day, the Government erroneously informed
the district court the petition was timely, due to a
miscalculation. Id.


                                          - 13 -
an abuse of discretion to raise timeliness sua sponte in that case

because "the State twice informed the U.S. District Court that it

'would not challenge, but [is] not conceding, the timeliness of

Wood's habeas petition,'" id. at 465, thereby evincing clear

gamesmanship.

            That is not the situation here.                Assuming arguendo that

similar concerns govern federal petitioner § 2255 cases as state

petitioner § 2254 cases, the Government did not "strategically

withh[o]ld the [limitations] defense or cho[o]se to relinquish it"

in order to reach the merits of Casey's petition.                        Id. at 472

(alteration       in    original)    (quoting       Day,   547   U.S.   at   210-11).

Rather,     the    Government        argued      procedural       default    (another

procedural bar) but made no mention of the defense of untimeliness

at that point.         The dissent makes much ado about the fact that the

same U.S. Attorney's Office raised the timeliness bar in opposition

to Dimott's and Collamore's petitions.                     But the Government's

inconsistency,          if   anything,       demonstrates        inadvertence,     not

stratagem -- it simply had nothing to gain by only raising one

procedural bar instead of two.

            Moreover,         unlike        in   Wood,     the     certificate      of

appealability          arguably    raised     the   timeliness     issue,    and   the

Government did brief it on appeal and argue that it did not waive

the timeliness bar.          In fact, the crux of the Government's position

is   that   petitioners           cannot    reset    the    one-year    statute     of


                                           - 14 -
limitations using § 2255(f)(3) because they fail to raise Johnson

II claims.      As such, we would not be rewarding the Government for

any gamesmanship before the district court if we were to bypass

its failure to raise the untimeliness defense at the outset before

the district judge.

             There is also no issue of procedural fairness.           Casey,

the losing party in district court on other grounds, had ample

notice of the timeliness defense -- beginning with the issues

raised in the certificate of appealability -- and the opportunity

to actually respond, both as to briefing and during oral argument

before this court, which he has done.           We would, by reaching the

timeliness      issue,   further    "[t]he    considerations    of    comity,

finality, and the expeditious handling of habeas proceedings" that

are at the very core of AEDPA.        Day, 547 U.S. at 208.    Accordingly,

the   balance    of   relevant     factors   favors   the   ability   of   the

Government to assert the timeliness defense now.4

             Indeed, contrary to the dissent's assertion that this

court "religiously" holds waiver against the Government, we --

along with other courts of appeals -- have upheld the discretion

of federal courts to deny habeas petitions on procedural grounds

in analogous contexts.5      See Oakes v. United States, 400 F.3d 92,


      4   We do not rule on the correctness of the district court's
holding that Casey's Johnson II claim was procedurally defaulted.
      5   And this case is clearly distinguishable from cases in
which other courts of appeals have declined to act sua sponte.

excusing the government's failure to raise the procedural default

bar); see also Coulter v. Kelley, 871 F.3d 612, 618 (8th Cir. 2017)

(finding that the district court did not err in considering

timeliness sua sponte when the State "did not knowingly and

intelligently waive its statute-of-limitations defense," and was,

at most, negligent); In re Williams, 759 F.3d 66, 69 (D.C. Cir.

2014) (finding that the court of appeals could raise, sua sponte,

the timeliness bar to deny petitioner's motion for a successive

petition for post-conviction relief).

          Accordingly, we proceed to consider the timeliness of

Casey's petition.

     2.   Burden of Proof and Production on Petitioner

          Casey contends that his petition is timely.     He urges

us to adopt a rule that, when faced with a silent record, we must

assume the district court sentenced the defendant pursuant to the

residual clause.    Casey does not, however, assert that he was in

fact sentenced under the residual clause.




See, e.g., United States v. Miller, 868 F.3d 1182, 1186 (10th Cir.
2017) (relying, in part, on the fact that the petitioner "ha[d]
been afforded no opportunity to respond to the Government's new
timeliness argument"); In re Jackson, 826 F.3d 1343, 1348 (11th
Cir. 2016) (emphasizing that "[n]either the Government nor [the
petitioner] . . . presented a position about a limitations
defense").


                               - 16 -
          In urging this rule, Casey asks us to break with our

time-honored precedent.    This circuit has long held that federal

post-conviction    petitioners    bear    the   burden   of    proof   and

production under § 2255, and must "establish[] by a preponderance

of the evidence that they are entitled to relief."            DiCarlo, 575

F.2d at 954.    Other circuits agree.     See, e.g., Stanley, 827 F.3d

at 566 ("As the proponent of collateral review, [the petitioner]

had to produce evidence demonstrating entitlement to relief."

(citations omitted)); In re Moore, 830 F.3d 1268, 1272 (11th Cir.

2016) (aggregating cases across seven circuits that hold the same).

          The Eleventh Circuit has applied this burden of proof

specifically to situations where federal petitioners allege that

they raise Johnson II claims.      See Beeman v. United States, 871

F.3d 1215, 1221 (11th Cir. 2017) ("We conclude and hold, that,

like any other § 2255 movant, a Johnson § 2255 claimant must prove

his claim.").     In Beeman, the court announced a clear rule: "To

prove a Johnson II claim, the movant must show that -- more likely

than not -- it was the use of the residual clause that led to the

sentencing court's enhancement of his sentence."         Id. at 1221-22.

A mere possibility is insufficient.6


     6    In re Chance, 831 F.3d 1335 (11th Cir. 2016), an Eleventh
Circuit case cited by the petitioners, construed silence in the
petitioner's favor. See id. at 1341. However, that case preceded
Beeman. And in any event, the opinion itself acknowledged that
its proposed rule lacked legal force because it was only dicta.
See id. at 1339.


                                 - 17 -
               This approach makes sense.          Petitioners should bear the

burden of proof because they were certainly present at sentencing

and knowledgeable about the conditions under which they were

sentenced.         Furthermore,     any    other    rule    would   undercut    an

animating principle of AEDPA: the presumption of finality.                     And

"[w]ithout finality, the criminal law is deprived of much of its

deterrent effect."        Teague v. Lane, 489 U.S. 288, 309 (1989).

               Casey fails to point to any evidence suggesting that he

was   sentenced     under    the   residual     clause. 7    Nevertheless,     the

dissent repeatedly insists that because the district judge found

Casey's Johnson II claim procedurally defaulted, he expressly

found that "Casey raised a timely Johnson II claim."                    This is

plainly incorrect.          That the district judge could have, but did

not, raise timeliness sua sponte, and instead relied on another

procedural bar, is not tantamount to finding that Casey was, in

fact,       sentenced   pursuant   to     the   residual    clause.     This    is

especially so when procedural default was the only procedural bar

the Government raised.         To say otherwise would be to hold that the

dismissal of a habeas petition on one ground is an express finding

that the petition is otherwise valid on every other ground.




        7 Casey did not ask for remand to the district court to
prove that he was in fact sentenced solely under the residual
clause. He has chosen to proceed on the record as it now exists.
See Beeman, 871 F.3d at 1221.


                                     - 18 -
             The     dissent       also     argues   that   because      the       district

court's order expressly stated that "Casey's Johnson claim is a

novel constitutional claim that applies retroactively," Casey,

2016    WL        6581178,     at     *3,      it    indicated         "clear[ly]         and

unambiguous[ly]" that he was sentenced pursuant to the residual

clause.      Again, not so.          The dissent takes this language out of

context.      That the district court found Casey had cause for his

procedural        default     --    because     Johnson     II    created      a    novel,

retroactively applicable right -- is not equivalent to finding, on

the merits, that Casey raised a valid Johnson claim.                        Otherwise,

any    petitioner       who        clears     the    procedural        default       hurdle

automatically succeeds on the merits.                 That cannot be right.

             The Eleventh Circuit decision that Casey flags, In re

Adams, 825 F.3d 1283 (11th Cir. 2016), lends no support to the

contrary.     There, the court permitted the petitioner's Johnson II

claim despite a silent record because clear Supreme Court and

Eleventh Circuit precedent at the time of sentencing held that a

conviction under the Florida burglary statute was an ACCA predicate

under the residual clause.                See id. at 1285.        This case presents

the opposite fact pattern.                  Our decision in Duquette held that

Maine burglary qualifies as a predicate offense under the ACCA's

enumerated clause.           See 778 F.3d at 317.            Although Duquette was

decided      in    2016,     the     opinion     describes       its    holding      as     a

"straightforward" application of the 1990 Supreme Court decision


                                            - 19 -
in Taylor v. United States, 495 U.S. 575 (1990).                   See 778 F.3d at

317.    Other district courts at the time of Casey's sentencing also

treated Maine burglary as a generic offense.                        For instance,

Dimott's and Collamore's sentences were found subject to the

enumerated clause based on the petitioners' Maine state burglary

convictions just a few years before.

              Casey    directs      our   attention   to   three    cases,   United

States v. Geozos, 870 F.3d 890 (9th Cir. 2017); United States v.

Winston, 850 F.3d 677 (4th Cir. 2017); and United States v. Taylor,

873    F.3d   476     (5th   Cir.    2017),    that   purportedly     espouse   his

requested approach.

              The Ninth Circuit in Geozos held that a state or federal

petitioner has a valid Johnson II claim whenever the sentencing

court "may have" relied on the residual clause.                870 F.3d at 896.

The court said it did so based on an extension of the Stromberg

principle, which prescribes that a general verdict is void if it

"may have rested" on an unconstitutional ground.                     Id. (quoting

Griffin v. United States, 502 U.S. 46, 53 (1991)).                   In the Ninth

Circuit's view, a post-conviction finding by a judge as to the

basis for a petitioner's enhanced sentence should not be treated

"any differently than a finding made by a jury for the purpose of

conviction."        Id.

              Our view is different.           We think the focus must be on

the fact that we are applying clear limits established by Congress


                                          - 20 -
for when federal post-conviction petitions may be entertained by

the federal courts, an issue not implicated at all by Stromberg.

There are also many reasons why collateral review is unique.

"Chief among them is the principle that 'direct appeal is the

primary avenue for review of a conviction or sentence . . . .

When    the   process    of   direct    review . . . comes       to   an   end,   a

presumption of finality and legality attaches to the conviction

and sentence.'"         In re Moore, 830 F.3d at 1272 (alterations in

original) (quoting Barefoot v. Estelle, 463 U.S. 880, 887 (1983)).

That presumption is irreparably undermined if the Government is

forced to bear the burden of proving that each Johnson II claimant

does not have a valid Johnson II claim.               The burden should fall

on the petitioner to establish by a preponderance of the evidence

a necessary element of his Johnson II claim -- that his ACCA

sentence rested on the residual clause.

              The Fourth Circuit in Winston agreed with the Ninth

Circuit as to state habeas claimants, but on different grounds.

The Fourth Circuit reasoned that "imposing the burden on movants

[to show they had been sentenced under the residual clause]. . .

would    result   in    'selective     application'       of   the   new   rule   of

constitutional     law     announced     in     Johnson    II,   violating    'the

principle of treating similarly situated defendants the same.'"

Winston, 850 F.3d at 682 (quoting In re Chance, 831 F.3d at 1341).

We think that does not follow.            Requiring habeas petitioners to


                                       - 21 -
establish -- by a preponderance of the evidence -- that they were

sentenced pursuant to the residual clause does not lead to treating

similarly    situated     defendants     differently.          Precisely     the

opposite: it is imposing a uniform rule.            That the burden is less

friendly to petitioners than the one put forth in Winston does not

make it unequal.

            Moreover,    Winston's     reliance     on   Teague    to   justify

shifting the burden of proof onto the Government is misplaced.                In

Teague, the Supreme Court held that "habeas corpus cannot be used

as a vehicle to create new constitutional rules of criminal

procedure unless those rules would be applied retroactively to all

defendants on collateral review."         489 U.S. at 316.        Although the

Court noted that "once a new rule is applied to the defendant in

the case announcing the rule, evenhanded justice requires that it

be applied retroactively to all who are similarly situated," id.

at   300,   it   never   said   that   evenhanded    justice      requires   the

Government to bear the burden of proving that the petitioner does

not have a valid claim for relief.          In fact, shifting the burden

would implicate one of the Supreme Court's chief concerns in

Teague: that the "costs imposed . . . by retroactive application

of new rules of constitutional law on habeas corpus" would "far

outweigh the benefits of this application" if "it continually

forces the [Government] to marshal resources in order to keep in

prison defendants whose trials and appeals conformed to then-


                                   - 22 -
existing constitutional standards."                489 U.S. at 310 (citations

omitted).

            Finally,    the    Fifth    Circuit's     decision     in    Taylor    is

clearly distinguishable.             In that case, the court held that a

federal prisoner had a valid Johnson II claim even though the

record was silent, and the district court later declared that the

"residual clause 'did not play any role in Movant's sentencing.'"

Taylor,    873   F.3d   at    481.     Although     the   court   described       the

approaches taken by the Fourth, Ninth, and Tenth Circuits, it did

not decide "which, if any, of these standards [it would] adopt."

Id. at 481-82.      Instead, the court held that "[the petitioner's]

claim merit[ed] relief" because "there was precedent suggesting

that Taylor's third predicate conviction could have applied only

under the residual clause."           Id. at 482.     No such precedent exists

here.     Rather, at the time of Casey's sentencing, many district

courts did not even consider the residual clause as the basis for

defendants' ACCA sentences when faced with predicate offenses

under state burglary statues similar to Maine's.                        See, e.g.,

United States v. Miller, 478 F.3d 48, 50-52 (1st Cir. 2007)

(Connecticut burglary statute); United States v. Bennett, 469 F.3d

46, 49-50 (1st Cir. 2006) (Rhode Island burglary statute); United

States    v.     Mastera,     435     F.3d   56,    60-62   (1st        Cir.   2006)

(Massachusetts burglary statute).




                                       - 23 -
             Our   view   is   different      from   those   taken    in   Geozos,

Winston, and Taylor.        Placing the burden of proof and production

on habeas petitioners is in accord with our precedent and with the

goals of AEDPA.      See Turner v. United States, 699 F.3d 578, 587

(1st Cir. 2012) (noting that "AEDPA's purpose is to further

finality of convictions" (citing Duncan v. Walker, 533 U.S. 167,

178 (2001))).      We hold that to successfully advance a Johnson II

claim on collateral review, a habeas petitioner bears the burden

of establishing that it is more likely than not that he was

sentenced solely pursuant to ACCA's residual clause.                     Casey has

not met that burden.        Instead, as noted, he has never argued that

he was actually sentenced under the residual clause.                 Accordingly,

we find Casey's petition, which -- like those of Dimott and

Collamore -- relies solely on the non-retroactive decision in

Mathis, untimely.8

                                       III.

             For   the    foregoing    reasons,      we   affirm   the     district

courts' dismissals of Dimott's, Collamore's, and Casey's § 2255

petitions.




     8    Casey also attempts to argue that Mathis is not new law,
but merely "clarifies" longstanding law.    This is in effect an
argument that Duquette was wrongly decided at the outset. That
again goes to the merits of his Mathis claim, and does not alter
the fact that Mathis does not apply retroactively on collateral
review. Cf. 136 S. Ct. at 2257.

-Dissenting Opinion Follows-




           - 25 -
             TORRUELLA, Circuit Judge (Joining in part and Dissenting

in part).      I join the majority in affirming the dismissals of

Dimott's and Collamore's § 2255 petitions as untimely.              However,

I   cannot   join   in   the   majority's    disparate   and    inconsistent

treatment of Casey's petition for habeas relief, as opposed to its

treatment of the other two petitions at issue, in order to avoid

what this case truly calls for: a re-evaluation of this Court's

opinion in Duquette in light of the Supreme Court's decision in

Mathis.

             In the cases of Dimott and Collamore, the majority

correctly gives "due weight" to the habeas judge's finding that

the petitioners were sentenced according to the ACCA's enumerated

clause because the habeas judge was also the sentencing judge.              It

is eminently reasonable that a sentencing judge is capable of

determining the basis upon which he or she imposed a sentence

enhancement when subsequently reviewing that sentence on a § 2255

habeas petition. See Schriro v. Landrigan, 550 U.S. 465, 495–96

(2007) (stating that a judge's memory deserves some deference

provided it is based on a complete review of the case).                   Here,

Judge Singal had the opportunity to review Dimott and Collamore's

cases prior to determining that he had sentenced them under the

enumerated     clause.    Thus,    that     determination      deserves     the

deference, as the panel majority recognizes.




                                   - 26 -
             The same deference must be given to the habeas judge who

reviewed Casey's petition, Judge Hornby, who -- like Judge Singal

in Dimott and Collamore's cases -- was the judge that sentenced

Casey.   On habeas review, Judge Hornby, also facing a silent record

as to the clause under which he applied Casey's ACCA sentencing

enhancement, found that Casey did raise a Johnson II claim --

meaning that his sentence was enhanced pursuant to the ACCA's

residual clause.     See Casey, 2016 WL 6581178, at *3.   Judge Hornby

analyzed the habeas petition accordingly. Id., at *3-5.      Yet, the

majority inexplicably fails to give Judge Hornby the same deference

that it gives to Judge Singal.

             The majority incorrectly assumes that my "insist[ence]"

that the district court found that Casey raised a timely Johnson

II claim is that the court analyzed the Government's procedural-

default argument.     This is wide of the mark.    Rather, I so find

after according Judge Hornby's words their clear and unambiguous

meaning.     See id., at *3 ("I conclude that . . . Casey's Johnson

claim is a novel constitutional claim that applies retroactively,

and he has therefore shown cause for [failing to argue that the

ACCA residual clause was unconstitutional at sentencing or on

appeal]."), *4 n.9 ("As I have determined above, Casey's Johnson

claim is a novel constitutional claim with retroactive application

. . . .").     The majority rationalizes its disregard of this plain

language by claiming that I "take [it] out of context."       Yet, as


                                - 27 -
the majority notes, should the district court have believed that

Casey had been sentenced pursuant to anything but the ACCA's

residual clause, it could have raised timeliness sua sponte.        The

district court was clearly aware that similar petitions had been

decided on timeliness grounds -- it even discussed Dimott in its

decision; should it have believed such an argument appropriate, it

would not have needed to reach the merits of Casey's Johnson II

claim in order to conduct a prejudice analysis.         See id. at *5.

But, it did not raise the issue, and after finding that Casey was

sentenced pursuant to the residual clause, embarked on the more

onerous procedural default analysis.       "Due regard for the trial

court's processes and time investment is . . . a consideration

appellate courts should not overlook."     Wood, 566 U.S. at 474.

          In   a   further   departure   from   this   Court's   guiding

judicial doctrines, the majority raises sua sponte the issue of

the timeliness of Casey's habeas petition, which the Government

did not argue below.   In doing so, the majority ignores the advice

provided by the Supreme Court in Wood that, in situations such as

this, "[a]though a court of appeals has discretion to address, sua

sponte, the timeliness of a habeas petition, appellate courts

should reserve that authority for use in exceptional cases."        Id.

at 473 (finding that the appellate court abused its discretion in

raising the timeliness issue sua sponte); see also Cole v. Int'l

Union, United Auto., Aerospace & Agric. Implement Workers of Am.,


                                - 28 -
533   F.3d   932,    936    (8th    Cir.    2008)     (applying    only    a     "narrow

exception" to established preservation rule).                       The Government

makes   no   argument      that    this    is   an    exceptional       case,    and   --

especially in light of Judge Hornby's finding that Casey raised a

timely Johnson II claim -- this is not the appropriate case for

the Court to act on its own accord.                  Here, as in Wood, where the

Government forewent an argument below, we should not exercise our

confined discretion to save the Government's waiver.

             To justify its divergence from Wood's guidance and find

that the Government did not forfeit its timeliness argument, the

majority speculates -- in the Government's favor -- as to the

reason that the Government did not advance this argument.                       I cannot

subscribe to this guesswork approach.                    This Court religiously

finds a party's failure to raise an argument before the district

court as waived on appeal.                See, e.g., United States v. Román-

Huertas, 848 F.3d 72, 77 (1st Cir. 2017) ("The Government did not

raise [petitioner's] untimely objection before the district court,

. . . and so it [is] waived . . . .");                Sotirion v. United States,

procedural default argument waived for failing to raise it as a

defense in the district court to a § 2255 petition).                            The same

waiver must apply here, and we should refrain from such "unguided

speculation."       Cf. Halloway v. Arkansas, 435 U.S. 475, 491 (1978)

(finding a harmless-error analysis inappropriate in assessing


                                          - 29 -
constitutional error of joint representation); Walsh v. Teltech

Systems, Inc., 821 F.3d 155, 160 (1st Cir. 2016) (stating that

appellate courts draw all reasonable inferences in favor of the

nonmoving party but ignore unsupported speculation when reviewing

an award of summary judgment).

           Moreover, I have significant qualms with the effect that

the majority's reasoning has on the waiver doctrine.    The majority

credits the Government for "brief[ing] [the timeliness issue] on

appeal and argu[ing] that it did not waive the timeliness bar."

Yet, this is precisely what the waiver doctrine is intended to

prevent.   Applying the majority's approach would allow any party

that chose not to raise an argument in the district court to simply

brief that issue on appeal and argue that it did not waive the

issue below.     In those circumstances, we would find the argument

waived, as we should in this one.       Further, the Government only

acknowledges its failure to raise the timeliness issue in a

footnote in its opening brief to this Court, providing scant

explanation as to why the claim was not raised below or why it

should not be treated as waived.        Instead, it states that the

petitioners have briefed the issue and that this Court may raise

it sua sponte.     Such an undeveloped address is hardly sufficient

to save the argument from waiver on appeal.        United States v.

Zannino, 895 F.2d 1, 17 (1st Cir. 1990) ("[I]ssues adverted to in




                               - 30 -
a perfunctory manner, unaccompanied by some effort at developed

argumentation, are deemed waived.").

               Instead, I would find that the Government relinquished

its timeliness argument in the district court.                      I note that this

same U.S. Attorney's Office (for the District of Maine) raised the

issue of timeliness in its oppositions to both Dimott's and

Collamore's § 2255 petitions, both filed within six weeks of its

opposition to Casey's petition.              While the majority attributes the

Government's decision not to advance this argument in response to

Casey's petition as inadvertence rather than strategy, I do not so

conjecture.        This strikes me as an appropriate basis for finding

that     the     Government      displayed         its     "clear     and      accurate

understanding of the timeliness issue" and "knew that it had an

arguable statute of limitations defense," but relinquished that

argument.       Wood, 566 U.S. at 474 (internal quotation marks and

citation omitted).

               Finally, the majority's finding that Casey failed to

satisfy his burden of proving by a preponderance of the evidence

that   he    was    sentenced    under      the    residual      clause   is   equally

unpersuasive.         The majority pronounces that, in the face of a

silent      record,    placing      the    burden    on     a    petitioner        "makes

sense . . . because they were certainly present at sentencing and

knowledgeable         about   the    conditions          under   which      they     were

sentenced."        I fail to see what could better satisfy the majority's


                                          - 31 -
evidentiary requirement that petitioner was sentenced under the

residual clause than a finding by the sentencing judge, who was

also "certainly present at sentencing" and far more knowledgeable

of his own sentencing decisions.    I have a difficult time thinking

of what further evidence, in the face of a silent record, could be

more convincing.   The majority suggests in a footnote that Casey

could have asked for a remand to the district court to prove that

he was sentenced solely under the residual clause; however, such

a request would have been nonsensical after the habeas judge

clearly already found as much.     See Casey, 2016 WL 6581178, at *3.

          Given the deference owed to the habeas judge here, I

would find that, under any of the standards announced by our sister

circuits and discussed by the majority,9 Casey has shown that he



     9   As the majority explains, there is an emerging split
amongst the circuit courts as to the burden of proof placed on
petitioners facing a silent record who, through a § 2255 petition,
maintain that their sentences were enhanced pursuant to the
residual clause of the ACCA.    The Fifth Circuit described this
split well in Taylor, 873 F.3d at 480-81 (citing Beeman, 871 F.3d
at 1221-22 (finding that a defendant must show that "more likely
than not" he was sentenced according to the residual clause);
Snyder, 871 F.3d 1122 (10th Cir. 2017) (stating that courts should
look to the law at the time of sentencing and determine whether a
defendant's convictions fell within the scope of the other ACCA
clauses); Geozos, 870 F.3d at 895 (holding that, "when it is
unclear whether a sentencing court relied on the residual clause
in finding that a defendant qualified as an armed career criminal,
but it may have, the defendant's § 2255 claim 'relies on' the
constitutional rule announced in Johnson II." (citing Winston, 850
F.3d at 682)); Winston, 850 F.3d at 682 (finding that imposing the
burden on movants would result in "selective application" of the
new rule announced in Johnson II)).


                              - 32 -
was sentenced pursuant to the residual clause and thus brought

forth a timely Johnson II claim.      This Court should analyze the

matter accordingly.     As the district court did below, we would

accordingly need to address whether Casey's claim is procedurally

defaulted for failing to raise it at trial or on direct appeal.

The district court found there to be cause for Casey not having

raised the issue, but that, while believing that Mathis casts

significant doubt on the vitality of Duquette, it was bound by

this Circuit's precedent to find that Maine burglary is generic

and also falls under the enumerated clause.         Casey, 2016 WL

6581178, at *5.   Accordingly, it found that Casey did not suffer

any actual prejudice.    Id. at *4.

           The district court was correct in its ruling given its

boundaries.   However, this Court is not so constrained.        See

United States v. Tavares, 843 F.3d 1, 11 (1st Cir. 2016) (stating

that the court may overturn prior panel decisions when controlling

authority is subsequently announced or when, in light of new

authority, the panel would likely have changed its "collective

mind." (quoting United States v. Pires, 642 F.3d 1, 9 (1st Cir.

2011))).   Mathis is subsequent controlling authority which calls

into question the vitality of our opinion in Duquette.   See United

States v. Whindleton, 797 F.3d 105, 113 (1st Cir. 2015) ("An

exception to the doctrine of stare decisis applies if '[a]n

existing panel decision [is] undermined by controlling authority,


                               - 33 -
subsequently   announced,       such   as   an   opinion   of   the   Supreme

Court . . . ." (alterations in original) (citing United States v.

Rodríguez-Pacheco, 475 F.3d 434, 441 (1st Cir. 2007))).                   In

Duquette, we found that because the Maine burglary statute contains

all of the elements of generic burglary, under Taylor, 495 U.S.

575, it qualified as generic burglary under the ACCA's enumerated

clause.   However, Mathis has undermined this analysis, instead

calling for us to determine if one (or more) of the elements of

Maine burglary is broader than the corresponding element of the

generic offense.        If so, then Maine's burglary statute, like

Iowa's burglary statute, cannot fall under the ACCA's enumerated

clause.

          While    we    have    not   conducted    this   re-analysis    of

Duquette, Casey's petition for habeas relief calls for us to do so

to determine if Casey suffered actual prejudice.           Addressing this

more difficult issue -- which the majority seeks to avoid -- is

necessary to decide this case.10

          Accordingly, I join in affirming the outcome proposed by

the majority in the cases of Dimott and Collamore, and respectfully




     10  As pointed out by the district court below, Casey, 2016
WL 6581178, at *5 n.16, and the Government in its Rule 28(j) letter
to the Court, numerous federal circuits have recently reviewed
state burglary statutes in light of Mathis to determine whether
they continue to qualify as enumerated felonies under the ACCA.
