ORDER
¶1 Held: The trial court’s denial of the defendant’s successive postconviction petition is affirmed where the defendant failed to establish cause for not raising her youth- based proportionate penalties challenge in an earlier proceeding.
¶2 Following a third-stage evidentiary hearing under the Post-Conviction Hearing Act (Act)
(725 ILCS 5/122-1 et seq. (West 2022)), the trial court denied the amended successive
postconviction petition filed by the defendant, Quinella Thompson. The defendant appeals,
arguing that the trial court erred in determining that the defendant failed to establish cause for not
raising her claims in her initial postconviction petition. The defendant also contends that the trial
court erred in rejecting her proportionate penalties claim based on a misapprehension that she had
adduced no evidence connecting the emerging research in juvenile brain science and her specific
circumstances. For the reasons that follow, we affirm.
1 ¶3 I. BACKGROUND
¶4 In October 2002, the defendant was convicted by a jury of first degree murder for her role
in the murder of an 80-year-old woman. The trial court subsequently sentenced her to 45 years in
prison. The defendant was 18 years old at the time of the offense. On direct appeal, the defendant
contended, in pertinent part, that her 45-year sentence was excessive in light of, among other
things, her youth. See People v. Thompson, No. 5-03-0300 (2004) (unpublished order under
Illinois Supreme Court Rule 23). This court disagreed and affirmed the sentence as modified after
correcting the mittimus to reflect the time she spent in presentencing incarceration. Id.
¶5 On November 2, 2007, the defendant filed a pro se postconviction petition, which indicated
that she was making an actual innocence claim, but she identified numerous violations of her rights
that occurred at the trial. On January 3, 2008, the trial court dismissed the defendant’s pro se
petition as frivolous and patently without merit. This court affirmed the summary dismissal of the
defendant’s pro se petition. See People v. Thompson, No. 5-08-0053 (2010) (unpublished order
under Illinois Supreme Court Rule 23). On November 24, 2020, the defendant filed a second pro se
petition for postconviction relief, arguing that her sentence violated the eighth amendment of the
United States Constitution (U.S. Const., amend. VIII). On December 15, 2020, the trial court
entered an order, granting the defendant 60 days to amend her postconviction petition to seek leave
of court to file a successive petition and to allege that she had satisfied the cause and prejudice test
required for successive postconviction petitions under section 122-1(f) of the Act (725 ILCS
5/122-1(f) (West 2018)).
¶6 On January 15, 2021, the defendant filed a pro se motion for leave to file a successive
postconviction petition along with a successive petition for postconviction relief, in which she
argued that her 45-year sentence amounted to an unconstitutional de facto life sentence where it
2 was imposed without consideration of the mitigating characteristics of youth, as set forth in Miller
v. Alabama, 567 U.S. 460 (2012), and its progeny. The defendant argued that her 45-year sentence
violated the eighth amendment of the United States Constitution (U.S. Const., amend. VIII) and
the proportionate penalties clause of the Illinois Constitution (Ill. Const. 1970, art. I, § 11). As for
the cause and prejudice test, the defendant argued that she established cause because the
substantive rule announced in Miller was unavailable to her at the time she filed her first
postconviction petition. The defendant further argued that she established prejudice because the
recent developments in the law applied retroactively on collateral review, and there was a
reasonable probability that she would have received a lesser sentence had the trial court considered
the mitigating circumstances of youth.
¶7 On January 28, 2021, the trial court entered an order, finding that the defendant had
established the cause and prejudice required for successive postconviction petitions. The trial court
also appointed counsel for the defendant and docketed the case for second stage postconviction
proceedings. On June 10, 2021, the defendant filed an amended successive petition for
postconviction relief, setting forth the same arguments as alleged in her pro se petition that, under
Miller and related Illinois authority, her 45-year sentence was an unconstitutional de facto life
sentence under the Illinois proportionate penalties clause and the eighth amendment of the United
States Constitution.
¶8 In the amended petition, the defendant acknowledged that, at sentencing, the trial court
considered her rehabilitative efforts while in jail. However, she noted that the trial court did not
consider the characteristics of youth addressed in Miller or how those characteristics affected her
conduct in this case. Specifically, the defendant asserted that the following information was not
considered: she had a difficult childhood in that she was in the foster care system because her
3 father was murdered when she was 5 years old, and her mother was a drug addict; she suffered
from undiagnosed mental health issues and was suicidal when she was approximately 12 years
old; she only attended school until the seventh grade; and at the time of the offense, she was in a
physically abusive relationship, which led to her conviction. Attached to the defendant’s petition
was her May 18, 2021, affidavit, in which she provided details about her childhood and her
rehabilitative efforts while incarcerated. Also, in support, the defendant’s amended petition
pointed to a 2015 Washington Post opinion piece and discussions in relevant case law about the
recent developments in scientific research on continued brain development in adolescents and
young adults.
¶9 Further, specifically regarding the defendant’s argument that her sentence violated the
eighth amendment, the defendant acknowledged that the supreme court had unambiguously drawn
the line for Miller-based claims under the eighth amendment at age 18. However, she argued that
the line should not be arbitrarily set at 18 and that the eighth amendment should also apply to
Miller-based claims brought by emerging adult offenders.
¶ 10 On February 9, 2022, the State filed a motion to dismiss the defendant’s amended
successive petition for postconviction relief, arguing that the defendant failed to make a sufficient
showing that the recent developments in scientific research about emerging adults specifically
applied to her. That same day, the trial court held a hearing on the State’s motion, at which the
trial court noted that the relevant case law was not very clear as to what evidence needed to be
shown at the second stage of the postconviction proceedings. However, the trial court found that
the case law mandated that a defendant be given an opportunity to develop an evidentiary record
on this issue. Thus, the trial court advanced the proportionate penalties claim to the third stage to
allow the defendant an evidentiary hearing on that claim. However, the trial court granted the
4 State’s motion to dismiss with regard to the defendant’s eighth amendment claim, noting that the
case law made it clear that Miller-based claims under the eighth amendment did not apply to
emerging adult offenders. Thereafter, the trial court entered a written order, granting the State’s
motion to dismiss as to the defendant’s claim based on the eighth amendment but denying the
motion regarding the proportionate penalties claim.
¶ 11 On October 20, 2022, the trial court entered an order, indicating that the parties had
stipulated that the trial court would consider and take judicial notice of Dr. James Garbarino’s
testimony on January 11, 2023, in the defendant’s case. The trial court noted that Dr. Garbarino’s
testimony was limited to the general scientific principles of brain development in young adults and
would not be specific to the defendant.
¶ 12 At the January 11, 2023, hearing, Dr. Garbarino, who was testifying as an expert witness
in developmental psychology and trauma, testified about the general scientific principles of brain
development in young adults. Dr. Garbarino testified that there had been considerable discussion
about when adolescence ended and the concept of emerging adulthood in the “last couple of
decades to deal with the fact” that there was a transitional period between being a juvenile and
reaching “full adulthood.” He explained that emerging adulthood was from age 18 to some point
in the 20s. He also explained that technological developments had allowed for the direct study of
human brains. As the technology became more available and “increasingly applied to studying
populations of normal or relatively normal individuals,” that led to a “situation where a
neuroscience [was] informing developmental psychology about adolescence and emerging
adulthood in a way that [was] historically new.”
¶ 13 Dr. Garbarino explained that brain development was a gradual process and full maturity
could not be presumed until about age 25. He then discussed various publications that articulated
5 the underlying scientific foundation for giving special sentencing protections to juveniles and
increasingly to emerging adults. He indicated that he did not believe that the details of the offense
had “any predicative value for later on.” He explained the various aspects of brain development
and brain structure that were still maturing at age 18; about how chronic trauma and/or adverse
environmental conditions could impair that development; about how the mitigating sentencing
factors relevant to a juvenile’s youth and its attendant circumstances, which were established in
Miller, applied to emerging adults; and about how brain structure and access to education impacted
rehabilitation. Dr. Garbarino also explained the concept of the “double whammy” where many of
these emerging adults had normal adolescence limitations while living in a socially toxic
environment, which undermined their prosocial development and slowed down the developmental
process. Dr. Garbarino concluded that the Miller factors should be applied to emerging adult
offenders and that there had been additional data and science related to 18- to 20-year-olds since
Miller.
¶ 14 Subsequently, at the August 22, 2023, third-stage evidentiary hearing, the defendant
testified that she was currently 42 years old and that she was 18 years and 8 months old at the time
of the offense. The defendant had met with Dr. Garbarino and also reviewed the report that he had
prepared as a result of her conversations with him. However, the report was not introduced into
evidence, and Dr. Garbarino never testified about the defendant’s specific circumstances. The
defendant testified about her childhood, noting that she was in foster care due to her mother’s
substance abuse issues, that she was not close to her biological family, and that she did not have a
close group of friends. She explained that she was angry, confused, and lacked direction. Also,
since she was living in other people’s homes, she never felt like she belonged. She only attended
school until the seventh grade. Shortly before her incarceration, she transitioned from a group
6 home into a transitional learning program. She did not appreciate the consequences of committing
the offense because she did not appreciate her life.
¶ 15 In comparison, post-incarceration, the defendant was calmer, was better at communicating,
was not as angry, had reestablished her relationship with God, and viewed life differently and
wanted better for herself. During the prosecution, she had difficulty communicating with her
attorney. She explained that her attorney only talked to her about her court appearances, so she did
not know what to expect. She also noted that she did not understand what she was fully dealing
with because she was young, did not know how to communicate, and was scared.
¶ 16 Also on August 22, 2023, the defendant’s attorney filed a certificate demonstrating
compliance with Illinois Supreme Court Rule 651(c) (eff. July 1, 2017). Thereafter, on September
1, 2023, the trial court entered an order, denying the defendant’s amended successive petition for
postconviction relief. First, the trial court found that the defendant failed to present any expert
testimony corroborating her contention that her brain was not fully developed or that she was more
akin to a juvenile than an adult at the time of the offense. The trial court concluded that, without
this testimony, the defendant was unable to meet her burden of establishing that she was entitled
to the Miller protections at sentencing.
¶ 17 Second, the trial court found that the case was governed by the supreme court’s decision
in People v. Moore, 2023 IL 126461, ¶¶ 1, 42, which found that Miller did not give the defendants,
who were 19 years old at the time of the offense, cause to raise successive postconviction claims
under the proportionate penalties clause of the Illinois Constitution. In making this decision, the
trial court acknowledged that it had previously found that the defendant had established cause and
prejudice, and permitted the defendant to file a successive postconviction petition, because none
of the cases recognizing the unique status of emerging adults, or the evolving science on juvenile
7 maturity and brain development, were in existence when the defendant filed her initial
postconviction petition. However, following that determination, Moore had made it clear that
Miller did not provide cause for a defendant advancing a proportionate penalties challenge in a
successive postconviction petition. Consequently, for that reason, as well as the fact that the
defendant had failed to meet her burden establishing that she was entitled to Miller protections,
the trial court denied the defendant’s amended successive postconviction petition. The defendant
appeals.
¶ 18 II. ANALYSIS
¶ 19 The Act allows an incarcerated defendant to challenge her conviction by asserting that her
conviction was the result of a substantial denial of her constitutional rights. 725 ILCS 5/122-1
(West 2022). The Act is not a substitute for an appeal, but rather, a collateral attack on the final
judgment. People v. Edwards, 2012 IL 111711, ¶ 21. The Act sets forth a three-stage process for
adjudicating a defendant’s claims. People v. Edwards, 197 Ill. 2d 239, 244 (2001). At the first
stage, the circuit court independently reviews the petition to determine whether it is frivolous or is
patently without merit. Id.; 725 ILCS 5/122-2.1 (West 2022). If the petition is not dismissed for
being frivolous or patently without merit, it advances to the second stage of the proceedings, at
which an indigent defendant is entitled to appointed counsel, the petition may be amended, and
the State may answer or move to dismiss. People v. Gaultney, 174 Ill. 2d 410, 418 (1996); 725
ILCS 5/122-5 (West 2022). At this stage, the trial court determines whether the petition and any
accompanying documentation make a substantial showing of a constitutional violation. Edwards,
197 Ill. 2d at 246. If no showing is made, the petition is dismissed. Id. However, if a substantial
showing of a constitutional violation is made, the petition advances to the third stage, and the trial
court conducts an evidentiary hearing. Id.
8 ¶ 20 The Act contemplates the filing of only one postconviction petition. 725 ILCS 5/122-1(f)
(West 2022); Edwards, 2012 IL 111711, ¶ 22. Accordingly, issues that could have been but were
not presented in an original or amended petition are forfeited, and issues that have previously been
raised and addressed on appeal will be barred pursuant to res judicata. People v. Tate, 2012 IL
112214, ¶ 8. However, the procedural bars of forfeiture and res judicata can be overcome where
fundamental fairness requires. People v. Pitsonbarger, 205 Ill. 2d 444, 458 (2002). In proceedings
under the Act, fundamental fairness is established by satisfying the cause and prejudice test, which
is codified in the Act. Id.; 725 ILCS 5/122-1(f) (West 2022).
¶ 21 To obtain leave of court to file a successive postconviction petition, the defendant must
demonstrate cause for her failure to raise the claim in the initial petition and prejudice from that
failure. 725 ILCS 5/122-1(f) (West 2022). For cause, the defendant must identify an objective
factor that impeded her ability to raise a specific claim during the earlier postconviction
proceedings. Pitsonbarger, 205 Ill. 2d at 460. For prejudice, the defendant must demonstrate that
the claim not raised during the initial postconviction proceedings so infected the trial that the
resulting conviction or sentence violates her due process rights. People v. Wrice, 2012 IL 111860,
¶ 48. Failure to state either cause or prejudice will be detrimental to a motion seeking leave to file
a successive petition. People v. Clark, 2023 IL 127273, ¶ 47. A defendant should be denied leave
of court to file a successive postconviction petition when it is clear, from a review of the successive
petition and the submitted documentation, that the claims alleged by the defendant fail as a matter
of law or where the successive petition with supporting documentation is insufficient to justify
further proceedings. People v. Smith, 2014 IL 115946, ¶ 35.
¶ 22 Here, on appeal, the defendant challenges the trial court’s finding that she failed to establish
cause and prejudice. Since the time that the trial court advanced the defendant’s proportionate
9 penalties claim to the third stage of the postconviction proceedings, case law has continued to
evolve in a manner that has significantly limited defendants’ ability to raise youth-based challenges
to their sentences in successive postconviction petitions. Thus, in light of the supreme court’s
decisions in People v. Dorsey, 2021 IL 123010, People v. Clark, 2023 IL 127273, and People v.
Moore, 2023 IL 126461, we are compelled to conclude that the defendant cannot establish the
requisite cause for failing to bring her proportionate penalties claim in her initial postconviction
petition.
¶ 23 In People v. Dorsey, our supreme court held that, although Miller announced a new
substantive rule under the eighth amendment, Miller did not provide cause for a juvenile offender
to raise a claim under the proportionate penalties clause. Dorsey, 2021 IL 123010, ¶ 74. In making
this decision, the supreme court reasoned that “Illinois courts have long recognized the differences
between persons of mature age and those who are minors for purposes of sentencing.” Id.
Accordingly, the supreme court concluded that, at best, Miller’s unavailability prior to 2012
“deprived defendant of some helpful support for his state constitutional law claim, which is
insufficient to establish cause.” (Internal quotation marks omitted.) Id. The supreme court then
relied on Dorsey in Clark, when it extended its holding to successive postconviction claims based
on a defendant’s intellectual disabilities. Clark, 2023 IL 127273, ¶¶ 66-67. In Clark, the supreme
court concluded that the unavailability of Miller did not impede the defendant’s ability to present
his proportionate penalties claim on direct appeal or his opportunity to raise the claim in his first
postconviction petition. Id. ¶ 67.
¶ 24 Shortly after Clark, in Moore, our supreme court held that young adult offenders could not
rely on the unavailability of Miller to establish the requisite cause for their failure to raise their
youth-based proportionate penalties challenges in the original postconviction proceedings. Moore,
10 2023 IL 126461, ¶¶ 40-42. The supreme court concluded that Miller did not directly apply to young
adults and thus did not provide cause for a young adult offender to raise a proportionate penalties
clause claim. Id. ¶ 40. The supreme court reiterated that, “long before Miller, Illinois law
recognized the special status of juvenile offenders for purposes of applying the principles under
the proportionate penalties clause.” (Internal quotation marks omitted.) Id. ¶ 41. Moreover, the
supreme court noted that the evidence and arguments raised at the defendants’ sentencing hearings
showed that the parties knew Illinois law recognized the special status of young adults. Id. ¶ 42.
¶ 25 The supreme court found that, “Miller does not present new proportionate penalties clause
principles with respect to discretionary sentencing of young adult offenders. Instead, [the]
defendant had the essential legal tools to raise his present proposed claim under the proportionate-
penalties clause when he filed his previous postconviction petitions.” (Internal quotation marks
omitted.) Accordingly, the supreme court concluded that, since Miller did not change the law
applicable to young adults, it did not provide cause for the proportionate penalties challenges
advanced by the defendants in their successive postconviction petitions. Id.
¶ 26 In an attempt to circumvent our supreme court’s precedent, the defendant here contends
that she is not relying on the unavailability of Miller as the sole cause for her failure to raise her
proportionate penalties claim earlier. Instead, she asserts that she is relying on the subsequent
neuroscientific research regarding the development of the brains of young adult offenders that has
become available following the Miller decision. This new evidence includes Dr. Garbarino’s
testimony about the emerging research on the maturation of the brain structure and brain
development and how that impacts a young adult’s thought process and rehabilitative potential. In
addition, her amended postconviction petition mentions a 2015 Washington Post opinion piece
and relevant case law that discusses brain development and the similarities between adolescents
11 and young adults. Thus, the defendant argues that, without the essential factual and evidentiary
support for her youth-based proportionate penalties claim, she was unable to bring the claim in her
initial postconviction petition.
¶ 27 Moreover, the defendant argues that, unlike in Moore, where the evidence and arguments
raised at the sentencing hearing indicated that the parties knew Illinois recognized the special status
of young adults, the defendant’s sentencing hearing demonstrated the opposite. Specifically, the
defendant contends that the only mention of her age at her sentencing hearing was the suggestion,
made by her counsel, that where the victim had lived a full life, the State’s requested 50-year
sentence would effectively end the defendant’s life.
¶ 28 However, even before the defendant filed her pro se postconviction petition in 2007, it was
already accepted, and recognized by Illinois courts, that fully developed adults were different from
young adults who were still developing. See People v. Haines, 2021 IL App (4th) 190612, ¶ 51.
Thus, although the new evidence cited by the defendant provides “some helpful support” for her
proportionate penalties claim, the defendant already had “the essential legal tools” for raising it
when she filed her initial postconviction petition. See Dorsey, 2021 IL 123010, ¶ 74; see also
Moore, 2023 IL 126461, ¶ 42. For newly discovered evidence to constitute cause, the lack of that
evidence must have impeded the defendant’s ability to raise the claim at an earlier proceeding.
However, Dorsey, Clark, and Moore all instruct that the claim at issue here “should be viewed as
nothing more than an extension of proportionate penalties claims that have existed all along.”
People v. Horshaw, 2024 IL App (1st) 182047-B, ¶ 62 (citing Dorsey, 2021 IL 123010, ¶ 74,
Clark, 2023 IL 127273, ¶¶ 92-93, and Moore, 2023 IL 126461, ¶¶ 40-42). Thus, although the fact
that Miller and the emerging research following Miller arguably gives the defendant a stronger
12 argument today than she had when she filed her initial postconviction petition, it is insufficient to
demonstrate cause according to Moore.
¶ 29 Accordingly, since we are bound by our supreme court’s decisions regarding age-based
proportionate penalties challenges for young adults, we find that the defendant did not demonstrate
cause for her Miller-based proportionate penalties claim. As our ruling on cause disposes of the
case, we need not address the issue of whether the defendant established prejudice. We also need
not address the defendant’s additional argument that the trial court incorrectly rejected her
proportionate penalties claim based on a misapprehension that she had adduced no evidence
connecting the juvenile brain science research to her character and her specific circumstances.
¶ 30 III. CONCLUSION
¶ 31 For the foregoing reasons, we affirm the judgment of the circuit court.
¶ 32 Affirmed.
