State of Nebraska, appellee, v.

John L. Lotter, appellant. ___ N.W.2d ___ Filed July 1, 2022. Nos. S-20-363, S-20-366, S-20-367.
1. Postconviction: Constitutional Law: Appeal and Error. In appeals from postconviction proceedings, an appellate court reviews de novo a determination that the defendant failed to allege sufficient facts to dem

onstrate a violation of his or her constitutional rights or that the record and files affirmatively show that the defendant is entitled to no relief. 2. Postconviction: Judgments: Appeal and Error. Whether a claim raised in a postconviction proceeding is procedurally barred is a ques

tion of law which an appellate court reviews independently of the lower court’s ruling. 3. Limitations of Actions. If the facts in a case are undisputed, the issue as to when the statute of limitations begins to run is a question of law. 4. Postconviction: Constitutional Law. Postconviction relief is a very narrow category of relief, available only to remedy prejudicial constitu

tional violations that render the judgment void or voidable. 5. Postconviction: Constitutional Law: Proof. A postconviction motion must allege facts which, if proved, constitute a denial or violation of a defendant’s rights under the U.S. or Nebraska Constitution, causing the judgment against the defendant to be void or voidable. 6. ____: ____: ____. Under the Nebraska Postconviction Act, an eviden

tiary hearing is not required when (1) the motion does not contain fac

tual allegations which, if proved, constitute an infringement of the mov

ant’s constitutional rights rendering the judgment void or voidable; (2) the motion alleges only conclusions of fact or law without supporting facts; or (3) the records and files affirmatively show that the defendant is entitled to no relief. 7. Postconviction. The need for finality in the criminal process requires that a defendant bring all claims for relief at the first opportunity.

8. Postconviction: Appeal and Error. It is fundamental that a motion for postconviction relief cannot be used to secure review of issues which were known to the defendant and could have been litigated on direct appeal. 9. ____: ____. When an issue could have been raised on direct appeal, it is procedurally barred from postconviction relief, no matter how the issues may be phrased or rephrased. 10. Postconviction: Pleadings. The effect of Neb. Rev. Stat. § 29-3001(3) (Reissue 2016) is to require that all available grounds for postconviction relief must be stated in the initial postconviction motion and, once that motion has been judicially determined, any subsequent postconviction motion regarding the same conviction and sentence may be dismissed by the district court unless the motion affirmatively shows on its face that the basis relied upon for relief was not available at the time of filing the prior motion. 11. ____: ____. A defendant is entitled to bring a successive postconviction motion only when the face of the motion affirmatively shows that the issues raised therein could not have been raised in prior motions. 12. Postconviction: Limitations of Actions: Sentences: Death Penalty. The 1-year limitation period set out in Neb. Rev. Stat. § 29-3001(4) (Reissue 2016) governs all postconviction motions, including successive motions and those challenging a death sentence. 13. Postconviction. For purposes of Neb. Rev. Stat. § 29-3001(4)(b) (Reissue 2016), the factual predicate for a postconviction claim is prop

erly understood as the important objective facts that support the claim. 14. Postconviction: Time. The 1-year period in Neb. Rev. Stat. § 29-3001(4)(b) (Reissue 2016) begins to run when the objective facts underlying the claim could reasonably be discovered, and that date is distinct from discovering that those facts are actionable. 15. ____: ____. The inquiry for purposes of Neb. Rev. Stat. § 29-3001(4)(b) (Reissue 2016) concerns when the important objective facts could rea

sonably have been discovered, not when the claimant should have dis

covered the legal significance of those facts. 16. Mental Competency. The factual predicate for an intellectual disability claim under Atkins v. Virginia, 536 U.S. 304, 122 S. Ct. 2242, 153 L. Ed. 335 (2002), does not depend on either a formal clinical diagnosis or a particular intelligence quotient score. 17. ____. The important objective facts supporting a claim of intellectual disability under Atkins v. Virginia, 536 U.S. 304, 122 S. Ct. 2242, 153 L. Ed. 335 (2002), include facts relating to subaverage intellectual func

tioning, deficits in adaptive functioning, and the onset of these deficits during the developmental period.- 880 - Nebraska Supreme Court Advance Sheets 311 Nebraska Reports STATE v . LOTTER Cite as 311 Neb. 878

18. Mental Competency: Presumptions. The plain language of Neb. Rev. Stat. § 28-105.01(3) (Cum. Supp. 2020) does not establish a strict cutoff score of 70 on an intelligence quotient test; rather, it creates an eviden

tiary presumption in favor of finding intellectual disability when the defendant has an intelligence quotient score of 70 or below on a reliably administered test. 19. Mental Competency: Evidence: Appeal and Error. Nebraska appel

late courts have not construed Neb. Rev. Stat. § 28-105.01(3) (Cum. Supp. 2020) in a way that would prohibit those with a score above 70 on an intelligence quotient test from presenting other evidence that would support a finding of intellectual disability. 20. Constitutional Law: Sentences. Generally, state courts considering a matter on collateral review must give retroactive effect to new substan

tive rules of federal constitutional law. Substantive rules of federal con

stitutional law include rules forbidding criminal punishment of certain primary conduct, as well as rules prohibiting a certain category of pun

ishment for a class of defendants because of their status or offense. 21. Postconviction: Constitutional Law: Time. Neither Hall v. Florida , 572 U.S. 701, 134 S. Ct. 1986, 188 L. Ed. 1007 (2014), nor Moore v. Texas , ___ U.S. ___, 137 S. Ct. 1039, 197 L. Ed. 2d 416 (2017), announced a new substantive rule of constitutional law that must be applied retroactively to cases on postconviction collateral review. 22. Postconviction: Death Penalty: Time. The holding in Sawyer v. Whitley , 505 U.S. 333, 112 S. Ct. 2514, 120 L. Ed. 2d 269 (1992), does not require a state court to excuse procedural defaults in postconviction cases or prevent a state court from enforcing its procedural or time bar rules when presented with a challenge to imposition of the death penalty on postconviction collateral review. 23. Postconviction: Time: Appeal and Error. Generally, when the timeli

ness of a postconviction motion is at issue, the defendant must raise all applicable arguments in the district court to preserve them for appel

late review. 24. Statutes: Legislature: Intent. When construing a statute, a court must determine and give effect to the purpose and intent of the Legislature as ascertained from the entire language of the statute considered in its plain, ordinary, and popular sense. 25. Statutes: Appeal and Error. The rules of statutory interpretation require an appellate court to give effect to the entire language of a statute, and to reconcile different provisions of the statutes so they are consistent, harmonious, and sensible. 26. Death Penalty: Sentences: Mental Competency: Statutes: Legislature: Pleadings. Neb. Rev. Stat. § 28-105.01(2) (Cum. Supp. 2020) establishes a statutory right prohibiting imposition of the death- 881 - Nebraska Supreme Court Advance Sheets 311 Nebraska Reports STATE v . LOTTER Cite as 311 Neb. 878 penalty on any person with an intellectual disability. To enforce that statutory right, the Legislature enacted a specific statutory procedure to allow a defendant facing the death penalty to file a verified motion and request a hearing to determine intellectual disability, before any sentenc

ing determination is made. 27. Statutes: Legislature: Intent: Words and Phrases. As a general prin

ciple of statutory construction, use of the phrase “notwithstanding any other provision of law” in a statute signals legislative intent to override other provisions of law that conflict with the statute. 28. Postconviction: Limitations of Actions: Words and Phrases. The phrase “notwithstanding any other provision of law” in Neb. Rev. Stat. § 28-105.01 (Cum. Supp. 2020) neither impacts nor overrides the pro

cedural and time limitations applicable to postconviction motions under the Nebraska Postconviction Act. 29. Death Penalty: Legislature: Initiative and Referendum. The Legislature’s repeal of the death penalty in 2015 Neb. Laws, L.B. 268, never went into effect, because upon the filing of a referendum petition appearing to have a sufficient number of signatures, operation of the legislative act was suspended so long as the verification and certification process ultimately determines that the petition had the required number of valid signatures. 30. Death Penalty: Sentences: Initiative and Referendum. Because 2015 Neb. Laws, L.B. 268, was suspended and never went into effect, any death sentences in effect at the time were unchanged. Appeal from the District Court for Richardson County: Vicky L. Johnson , Judge. Affirmed. Timothy S. Noerrlinger, of Naylor & Rappl, and Rebecca E. Woodman, pro hac vice, for appellant. Douglas J.

Stacy , J. In this successive motion for postconviction relief, John L. Lotter presents two claims challenging the constitutionality- 882 - Nebraska Supreme Court Advance Sheets 311 Nebraska Reports STATE v . LOTTER Cite as 311 Neb. 878 of his death sentences. His first claim alleges the sentences were effectively vacated, and then unconstitutionally “reim

posed,” as a result of the legislative process surrounding L.B. 268—a bill passed by the Nebraska Legislature in 2015 1 and repealed by public referendum thereafter. We refer to this as Lotter’s “L.B. 268 claim.” His second claim alleges that he was diagnosed as intellectually disabled in 2018 and, therefore, is ineligible for imposition of the death penalty under the U.S. Supreme Court’s holding in Atkins v. Virginia. 2 We refer to this as Lotter’s “ Atkins claim.” The district court denied postconviction relief on both of Lotter’s claims without conducting an evidentiary hearing. It determined the L.B. 268 claim was meritless under settled precedent. It did not reach the merits of the Atkins claim because it determined the claim was both procedurally barred and time barred under Nebraska postconviction law. Lotter appeals, arguing he was entitled to an evidentiary hearing on both claims. We affirm.
I. BACKGROUND In 1995, a jury convicted Lotter of three counts of first degree murder, three counts of use of a weapon to commit a felony, and one count of burglary. 3 He was sentenced to death for each murder conviction and to terms of incarceration on the convictions for burglary and use of a weapon. 4 On direct appeal, the burglary conviction was vacated and all other convictions and sentences were affirmed. 5 Lotter’s criminal

.- 883 - Nebraska Supreme Court Advance Sheets 311 Nebraska Reports STATE v . LOTTER Cite as 311 Neb. 878 judgments became final on June 7, 1999, when the U.S. Supreme Court denied his petition for writ of certiorari. 6 Between 1999 and 2017, Lotter filed four motions for post

conviction relief, all of which were found to be meritless. 7 In addition, Lotter filed an unsuccessful motion for postconvic

tion DNA testing in 2001, 8 and unsuccessful petitions for fed

eral habeas corpus relief in 2011 9 and 2017. 10 None of Lotter’s prior postconviction motions alleged a claim that he is intel

lectually disabled under Atkins. On March 27, 2018, Lotter filed, in each of his three crimi

nal cases, the operative motions for postconviction relief at issue in this appeal. The verified motions were identical, and the district court consolidated them and generally referred to them collectively as Lotter’s fifth postconviction motion. For ease of reference, we do the same. As stated, Lotter’s fifth postconviction motion alleges two grounds for relief. Lotter’s L.B. 268 claim alleges that in 2015, when the Legislature passed L.B. 268 abolishing the death penalty, it effectively vacated his death sentences and imposed life sentences. Lotter alleges that when L.B. 268 was subsequently repealed by public referendum, it resulted in “re-imposition” of his death sentences, which violated his

LOTTER Cite as 311 Neb. 878 constitutional right to due process, violated his constitutional right to be free from cruel and unusual punishment, and amounted to an unconstitutional bill of attainder. Lotter’s Atkins claim alleges that in March 2018, his attor

ney retained Ricardo Weinstein, Ph.D., to determine whether Lotter is intellectually disabled. After evaluating Lotter’s intel

lectual and adaptive functioning, Weinstein issued a report con

cluding that Lotter “qualifies for the diagnosis of Intellectual Developmental Disability (formerly Mental Retardation).” On March 27, 2018, Lotter amended his fifth postconviction motion to add a claim that he is constitutionally ineligible for imposition of the death penalty under Atkins

. 11 A copy of Weinstein’s report was attached as an exhibit to the opera

tive motion. In February 2020, the court held what was characterized as a records hearing 12 on Lotter’s fifth postconviction motion. Thereafter, the court entered an order denying postconviction relief on both claims without conducting an evidentiary hear

ing. In rejecting Lotter’s L.B. 268 claim, the district court relied on several recent postconviction opinions from this court rejecting nearly identical claims as meritless. 13 Based on that precedent, the court concluded as a matter of law that Lotter’s L.B. 268 claim did not entitle him to postconviction relief. The court did not address the merits of Lotter’s Atkins claim, because it determined the claim was both procedurally

LOTTER Cite as 311 Neb. 878 barred and time barred under Nebraska postconviction law. The court found the claim was procedurally barred because Lotter had not raised it in any of his postconviction motions filed after 2002, when Atkins announced the constitutional rule that criminals who are intellectually disabled are ineligible for imposition of the death penalty. The court found that Lotter’s Atkins claim was time barred under Neb. Rev. Stat. § 29-3001(4) (Reissue 2016), because it had not been filed within 1 year from any of the five trig

gering events identified in that statute. More specifically, the court rejected Lotter’s argument that his Atkins claim was timely under § 29-3001(4)(b), reasoning that Lotter could have, with reasonable diligence, discovered the factual predicate for his Atkins claim more than 1 year before he filed the fifth postconviction motion. The court also rejected Lotter’s argu

ment that his Atkins claim was timely under § 29-3001(4)(d), which requires that a postconviction claim be filed within 1 year from “[t]he date on which a constitutional claim asserted was initially recognized by the Supreme Court of the United States or the Nebraska Supreme Court . . . .” The court rea

soned that Lotter’s claim was based on the constitutional right first announced nearly 20 years ago in Atkins , and it rejected Lotter’s contention that his claim was based on a new consti

tutional right recognized in the 2017 case of Moore v. Texas (Moore I) , 14 a case we discuss later in our analysis. After concluding that neither of the claims presented in Lotter’s fifth postconviction motion entitled him to relief, the court denied the motion without an evidentiary hearing. Lotter filed this timely appeal.
II. ASSIGNMENT OF ERROR Lotter assigns, consolidated and restated, that the district court erred by not granting an evidentiary hearing on both of the claims alleged in his fifth successive motion for postcon

viction relief.

III. STANDARD OF REVIEW [1] In appeals from postconviction proceedings, an appel

late court reviews de novo a determination that the defendant failed to allege sufficient facts to demonstrate a violation of his or her constitutional rights or that the record and files affirma

tively show that the defendant is entitled to no relief. 15 [2,3] Whether a claim raised in a postconviction proceeding is procedurally barred is a question of law which an appel

late court reviews independently of the lower court’s ruling. 16 Similarly, if the facts in a case are undisputed, the issue as to when the statute of limitations begins to run is a question of law. 17
IV. ANALYSIS To address Lotter’s assignments of error, we begin by reviewing the legal standards, both substantive and procedural, which govern proceedings under the Nebraska Postconvic

tion Act. 18
1. Standards Governing Postconviction Relief [4,5] In Nebraska, postconviction relief is a very narrow category of relief, available only to remedy prejudicial con

stitutional violations that render the judgment void or void

able. 19 Under the postconviction statutes, defendants in cus

tody under sentence “may file a verified motion, in the court which imposed such sentence, stating the grounds relied upon and asking the court to vacate or set aside the sentence.” 20 Such a motion must allege facts which, if proved, constitute a

20 § 29-3001(1).- 887 - Nebraska Supreme Court Advance Sheets 311 Nebraska Reports STATE v . LOTTER Cite as 311 Neb. 878 denial or violation of his or her rights under the U.S. or Nebraska Constitution, causing the judgment against the defend ant to be void or voidable. 21 [6] The Nebraska Postconviction Act requires a court to grant a prompt hearing on a motion for postconviction relief “[u]nless the motion and the files and records of the case show to the satisfaction of the court that the prisoner is entitled to no relief . . . .” 22 Under this standard, an evidentiary hearing is not required when (1) the motion does not contain factual allegations which, if proved, constitute an infringement of the movant’s constitutional rights rendering the judgment void or voidable; (2) the motion alleges only conclusions of fact or law without supporting facts; or (3) the records and files affirma

tively show that the defendant is entitled to no relief. 23 In addition to the substantive rules governing postconviction relief, there are procedural rules which can bar postconviction relief regardless of the merits of a particular claim. Here, the district court determined that Lotter’s Atkins claim was both procedurally barred and time barred under Nebraska law. We recite the general principles governing procedural bars and time bars in the next two sections of this opinion, and apply those principles later in our analysis. (a) Procedural Limitations on Postconviction Relief [7-9] The need for finality in the criminal process requires that a defendant bring all claims for relief at the first oppor

tunity. 24 Therefore, it is fundamental that a motion for post

conviction relief cannot be used to secure review of issues

which were known to the defendant and could have been liti

gated on direct appeal. 25 We have explained that when an issue could have been raised on direct appeal, it is procedurally barred from postconviction relief, 26 no matter how the issues may be phrased or rephrased. 27 [10,11] Additionally, the statute governing postconviction relief expressly provides that a “court need not entertain a second motion or successive motions for similar relief on behalf of the same prisoner.” 28 We have long construed this provision to require that all available grounds for postconvic

tion relief must be stated in the initial postconviction motion and, once that motion has been judicially determined, any sub

sequent postconviction motion regarding the same conviction and sentence may be dismissed by the district court unless the motion affirmatively shows on its face that the basis relied upon for relief was not available at the time of filing the prior motion. 29 Stated differently, a defendant is entitled to bring a successive postconviction motion only when the face of the motion affirmatively shows that the issues raised therein could not have been raised in prior motions. 30 In the

LOTTER Cite as 311 Neb. 878 absence of such affirmative allegations, there is “no justifica

tion for allowing a prisoner to continue litigation endlessly by piecemeal post conviction attacks on his conviction and sentence.” 31 A prisoner cannot wait to see if some postconvic

tion claims will succeed and, when they do not, dust off other claims and subsequently attempt to litigate them. 32 (b) Time Limitations on Postconviction Claims In 2011, the Legislature amended the Nebraska Postconviction Act to establish a 1-year limitations period for filing postcon

viction motions. 33 Section 29-3001(4) of the act provides: (4) A one-year period of limitation shall apply to the filing of a verified motion for postconviction relief. The one-year limitation period shall run from the later of: (a) The date the judgment of conviction became final by the conclusion of a direct appeal or the expiration of the time for filing a direct appeal; (b) The date on which the factual predicate of the constitutional claim or claims alleged could have been discovered through the exercise of due diligence; (c) The date on which an impediment created by state action, in violation of the Constitution of the United States or the Constitution of Nebraska or any law of this state, is removed, if the prisoner was prevented from fil

ing a verified motion by such state action; (d) The date on which a constitutional claim asserted was initially recognized by the Supreme Court of the United States or the Nebraska Supreme Court, if the newly recognized right has been made applicable retro

actively to cases on postconviction collateral review; or (e) August 27, 2011.

LOTTER Cite as 311 Neb. 878 [12] The 1-year limitation period set out in § 29-3001(4) governs all postconviction motions, including successive motions 34 and those challenging a death sentence. 35 With this substantive and procedural framework in mind, we address Lotter’s assignments of error. Because Lotter’s primary arguments on appeal pertain to his Atkins claim, we address that claim first.
2. Lotter’s Atkins Claim Lotter argues the district court erred by failing to grant him an evidentiary hearing on his Atkins claim. As stated, the district court denied an evidentiary hearing on Lotter’s Atkins claim after determining it was both procedurally barred and time barred under Nebraska law. To avoid being procedurally barred, the face of Lotter’s fifth postconviction motion must affirmatively show that his Atkins claim could not have been raised in any of his prior postconviction motions. 36 And to avoid being time barred under § 29-3001(4), Lotter’s Atkins claim must have been filed within 1 year from one of the triggering events in that statute. As we read Lotter’s fifth postconviction motion, he asserts three reasons why his Atkins claim is not procedurally barred or time barred. The first two are somewhat interrelated, in that he argues the face of his fifth successive motion affirmatively shows he could not have raised an Atkins claim in any of his prior postconviction motions because (1) the factual predicate for his claim did not exist until he was diagnosed as intellec

tually disabled in March 2018 37 and/or (2) he could not have known he had a viable Atkins claim until the U.S. Supreme released its opinion in Moore I

. 38 Alternatively, Lotter’s

tually disabled, he can overcome Nebraska’s procedural and time bars by asserting a claim of “‘actual innocence’” under the U.S. Supreme Court’s holding in Sawyer v. Whitley. 39 For the sake of completeness, we also note that Lotter’s appellate briefing presents an issue which was not expressly alleged in his fifth postconviction motion: He asserts that the language of Neb. Rev. Stat. § 28-105.01(2) (Cum. Supp. 2020), which states, “Notwithstanding any other provision of law, the death penalty shall not be imposed upon any person with an intellectual disability,” effectively exempts an Atkins claim from all of the procedural and time limitations set out in the Nebraska Postconviction Act, and allows such a claim to be raised at any time. To analyze Lotter’s arguments, we begin with a review of the U.S. Supreme Court cases recognizing and refining the con

stitutional rule that forbids imposing the death penalty on those who are intellectually disabled. We then review Nebraska’s statute and case law defining intellectual disability for purposes of imposing the death penalty. (a) U.S. Supreme Court Precedent In the 2002 case of Atkins , 40 the U.S. Supreme Court first held that imposing the death penalty on “mentally retarded criminals” amounts to cruel and unusual punishment prohibited by the Eighth Amendment. The clinical term “mental retar

dation” has since been changed to “intellectual disability,” 41

LOTTER Cite as 311 Neb. 878 and this opinion uses the current clinical term unless quoting directly from earlier opinions. The majority in Atkins acknowledged that just a decade earlier, in its 1989 opinion in Penry v. Lynaugh , 42 it found “insufficient evidence of a national consensus against execut

ing mentally retarded people convicted of capital offenses for us to conclude that it is categorically prohibited by the Eighth Amendment.” But Atkins observed that in the years follow

ing Penry , Congress and at least 18 state legislatures, includ

ing Nebraska’s, had enacted laws generally “prohibiting the execution of mentally retarded persons.” 43 The Atkins majority viewed that as a national legislative consensus that “death is not a suitable punishment for a mentally retarded criminal.” 44 The majority concluded that imposing the death penalty on this class of offenders did not further the goals of deterrence or retribution underpinning the death penalty, and it found “no reason to disagree with the judgment of ‘the legislatures that have recently addressed the matter.’” 45 Atkins therefore announced a new constitutional rule which categorically for

bids imposing the death penalty on persons who are intellec

tually disabled. However, the majority in Atkins did not adopt a specific test for determining which offenders are intellectually dis

abled, observing there was not yet a “national consensus” on that question. 46 Instead, Atkins expressly left to the states “‘the task of developing appropriate ways to enforce the constitutional restriction.’” 47 But the Atkins majority empha

. 51 In each post- Atkins case, the Court measured the state’s definition of intellectual disability against the current clinical definitions and the medical community’s diagnostic framework, which it has consistently described as having three criteria: “[1] significantly subaverage intellectual functioning, [2] deficits in adaptive functioning[,] and [3] onset of these deficits dur

LOTTER Cite as 311 Neb. 878 least one of these post- Atkins cases to argue that his intellectual disability claim could not have been filed sooner than 2018, we summarize those cases before addressing his arguments. In the 2014 case of Hall v. Florida , 53 the Court examined Florida’s statutory definition of intellectual disability, which appeared on its face to incorporate the diagnostic framework referenced in Atkins . But the Florida Supreme Court had con

strued the statutory definition to impose a strict intelligence quotient (IQ) cutoff score of 70, and, under that construction, defendants with an IQ above 70 were prohibited from present

ing other evidence of intellectual disability, including evidence of adaptive deficits. Hall found that Florida’s definition of intellectual disability, as interpreted by its courts, was uncon

stitutional to the extent it considered an IQ score to be final and conclusive evidence of a defendant’s intellectual capacity. Such a construction, Hall explained, was not “informed by the views of medical experts,” 54 because the medical community does not support a fixed IQ cutoff, and instead “understand[s] that an IQ test score represents a range rather than a fixed number.” 55 Hall instructed that when using IQ test scores “to asses a defendant’s eligibility for the death penalty, a State must afford these test scores the same studied skepticism that those who design and use the tests do” 56 and therefore must take into account an IQ test’s “‘standard error of meas

urement’” or “SEM” range. 57 And when a defendant’s IQ

intellectual disability as “‘significantly subaverage general intellectual functioning existing concurrently with deficits in adaptive behavior and manifested during the period from conception to age 18’” and defined “‘significantly subaverage general intellectual functioning’” as “‘performance that is two or more standard deviations from the mean score on a standardized intelligence test’”).

LOTTER Cite as 311 Neb. 878 score falls within the test’s acknowledged margin of error, the defendant must be allowed to present additional evidence of intellectual disability, including testimony regarding adaptive deficits. The Hall majority stated that the “legal determination of intellectual disability is distinct from a medical diagnosis, but it is informed by the medical community’s diagnostic framework.” 58 The majority in Hall stopped short of holding that a state’s definition of intellectual disability will not satisfy the principles of Atkins unless it complies in all respects with the current diagnostic criteria employed by psychiatric profes

sionals, but it again emphasized that courts may “not disregard these informed assessments.” 59 In the 2017 case of Moore I , the U.S. Supreme Court consid

ered the sufficiency of the definition used by the Texas Court of Criminal Appeals (Texas CCA) to find the defendant was not intellectually disabled. 60 The Supreme Court was critical of the definition applied by the Texas CCA, because it departed from the accepted clinical standards discussed in Atkins and Hall

. 61 Among other shortcomings, the Texas definition relied on outdated lay perceptions and lay stereotypes to determine who was intellectually disabled. And when assessing deficits in adaptive functioning, the definition deviated from prevail

ing clinical standards by overemphasizing adaptive strengths. Based on these and other shortcomings, the Supreme Court held that the definition of intellectual disability relied upon by the Texas CCA created an unacceptable risk that the death penalty would be imposed on persons with intellectual dis

abilities, in violation of Atkins

. Moore I therefore vacated the defendant’s death sentence and remanded the matter for further proceedings in accordance with the opinion.

LOTTER Cite as 311 Neb. 878 On remand, the Texas CCA reevaluated the evidence and again concluded the defendant did not meet the definition of an intellectually disabled person. The U.S. Supreme Court reversed that decision in Moore v. Texas ( Moore II ), 62 reason
ing that on remand, the Texas CCA may have used different language, but much of its analysis suffered from the same shortcomings identified in Moore I. The Supreme Court there

fore not only reversed the judgment of the Texas CCA, but affirmatively held that the defendant had shown he was a per

son with an intellectual disability and thus was ineligible for imposition of the death penalty under Atkins

. (b) Nebraska’s Definition of Intellectual Disability In 1998, while Lotter’s case was pending on direct appeal, the Nebraska Legislature amended § 28-105.01 to provide: “Notwithstanding any other provision of law, the death penalty shall not be imposed upon any person with mental retardation.” 63 This statute was referenced in Atkins to sup

port the Court’s finding of a national legislative consensus that “the mentally retarded should be categorically excluded from execution.” 64 In 2013, the language of § 28-105.01(2) was amended to use the current clinical term “intellectual disabil

ity” instead of “mental retardation.” 65 Currently, the relevant provisions of § 28-105.01 provide: (2) Notwithstanding any other provision of law, the death penalty shall not be imposed upon any person with an intellectual disability; (3) As used in subsection (2) of this section, intel

lectual disability means significantly subaverage gen

eral intellectual functioning existing concurrently with

(4) If (a) a jury renders a verdict finding the existence of one or more aggravating circumstances . . . the court shall hold a hearing prior to any sentencing determina

tion proceeding . . . upon a verified motion of the defense requesting a ruling that the penalty of death be precluded under subsection (2) of this section. If the court finds, by a preponderance of the evidence, that the defendant is a person with an intellectual disability, the death sentence shall not be imposed. Our 2010 opinion in State v. Vela 66 is the only case to date where we have applied the definition of intellectual disability in § 28-105.01(3). In Vela , the defendant was convicted of five counts of first degree murder. After the jury found the existence of aggravating circumstances, 67 the defendant filed a verified motion using the procedure in § 28-105.01(4)(a), seeking a ruling that he was intellectually disabled and there

fore ineligible for imposition of the death penalty. After an evidentiary hearing, the district court found the defend

ant had proved “significantly subaverage general intellectual functioning” 68 because the evidence showed he had a fullscale IQ test score of 75 on a reliably administered test and, adjusted for the SEM, the court considered that a score in a “‘range between 75 and 70.’” 69 But the district court found the defendant failed to prove, by a preponderance of the evidence, 70 that he also had significant “deficits in adaptive behavior.” 71 The court therefore overruled the motion, after

On direct appeal, we found no error in the district court’s conclusion that the defendant failed to prove he was intellec

tually disabled for purposes of § 28-105.01(2). Our analysis focused primarily on the court’s finding that the defendant had not proved the second factor of Nebraska’s statutory test, relat

ing to deficits in adaptive behavior. Vela was decided before Hall and both Moore cases, but our analysis relied on Atkins and appropriately emphasized the need to construe Nebraska’s statutory factors in a manner consistent with “current clinical models.” 72 Vela recognized that “[m]ental retardation is a clini

cal diagnosis” 73 and that “to reach any meaningful determina

tion of whether a convicted defendant with an IQ in the low 70’s is a person with mental retardation” courts must apply the current clinical diagnostic standards. 74 With this jurisprudential and statutory background in mind, we summarize Lotter’s allegations regarding his Atkins claim, after which we consider, de novo, whether that claim is proce

durally barred or time barred. 75 (c) Lotter’s Allegations of Intellectual Disability Lotter’s fifth successive postconviction motion alleged that in 2018, his attorney retained an expert to evaluate whether Lotter is intellectually disabled. The expert reviewed Lotter’s records, conducted interviews, and administered testing to determine Lotter’s current intellectual and adaptive function

ing. In March 2018, the expert prepared a report conclud

ing that Lotter “qualifies for the diagnosis of Intellectual Developmental Disability.” Lotter attached that report to

75 See Mata, supra note 13.- 899 - Nebraska Supreme Court Advance Sheets 311 Nebraska Reports STATE v . LOTTER Cite as 311 Neb. 878 his fifth postconviction motion. Among other things, the report states that in 2018, Lotter’s full-scale IQ was 67, which the expert described as “consistent with mild intellectual disabil

ity.” In addition to the IQ score, the report states that Lotter “has significant impairments in all three domains of adaptive functioning, including conceptual, social, and practical,” and that “Lotter’s problems are developmental in nature and were present since childhood.” The report also states that when Lotter was approximately 10 years old, testing by his treating psychologist showed a full-scale IQ of 76. The State’s briefing on appeal also directs us to historical evidence in the existing record regarding Lotter’s IQ, including a defense witness who testified during the sentencing phase that Lotter’s full-scale IQ was 92. (d) Lotter’s Arguments As stated, the district court concluded that Lotter’s Atkins claim is procedurally barred because it could have been raised in any of his prior postconviction motions after Atkins was decided in 2002. Additionally, the court concluded the Atkins claim was time barred, rejecting Lotter’s arguments it was timely under either § 29-3001(4)(b) or § 29-3001(4)(d). On appeal, Lotter challenges the district court’s conclusion that his Atkins claim is procedurally barred and time barred. He also argues that the procedural and time bars in the Nebraska Postconviction Act do not apply to an Atkins claim. We address each of Lotter’s arguments in turn. (i) Lotter’s Claim Not Timely Under § 29-3001(4)(b) [13-15] Under § 29-3001(4)(b), a postconviction claim is timely if it is filed within 1 year of the date “on which the factual predicate of the constitutional claim or claims alleged could have been discovered through the exercise of due dili

gence.” The factual predicate for a postconviction claim is properly understood as the “important objective facts” that- 900 - Nebraska Supreme Court Advance Sheets 311 Nebraska Reports STATE v . LOTTER Cite as 311 Neb. 878 support the claim. 76 We have explained that the 1-year period in § 29-3001(4)(b) begins to run when the objective facts under

lying the claim could reasonably be discovered, and that date is “distinct from discovering that those facts are actionable.” 77 In other words, the inquiry for purposes of § 29-3001(4)(b) con

cerns when the important objective facts could reasonably have been discovered, not when the claimant should have discovered the legal significance of those facts. 78 Lotter argues the factual predicate of his Atkins claim could not reasonably have been discovered until March 2018, when testing showed he had a full-scale IQ of 67 and an expert diagnosed him as intellectually disabled. For the same reason, Lotter argues he could not have raised an Atkins claim in any of his prior postconviction motions, and thus the claim should not be procedurally barred. We disagree. [16,17] The factual predicate for an intellectual disability claim under Atkins does not depend on either a formal clinical diagnosis or a particular IQ score. Instead, the important objec

tive facts supporting a claim of intellectual disability are those relating to the clinical diagnostic factors discussed in Atkins and the factors set out in § 28-105.01. As such, the factual predicate of an Atkins claim necessarily includes facts relating to subaverage intellectual functioning, 79 deficits in adaptive functioning, 80 and the “onset of these deficits during the devel

opmental period.” 81 Our review of the existing record in this case belies Lotter’s argument that he could not, with reasonable diligence, have discovered the important objective facts supporting an

Atkins claim before 2018. In Lotter’s direct appeal in 1998, we discussed the following expert testimony: Lotter has several mental disorders that have been ongo

ing since birth, that Lotter had those disorders at the time the crimes were committed, and that Lotter would continue to have those disorders. [A medical expert] described Lotter as “extremely dysfunctional” and stated that Lotter’s mental disorders impaired his ability to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of the law. 82 During Lotter’s trial, the medical expert also testified there was a “high probability” that Lotter has “organic damage in the brain.” The record also shows that in 1981, at the age of 10, Lotter received a full-scale IQ test score of 76. While such a score, even after being adjusted for the SEM, would still be above 70, and thus would not support the statutory presump

tion of intellectual disability under § 28-105.01(3), Lotter is simply wrong to suggest that an adjusted IQ score in the low 70s could not support a finding of intellectual disability in Nebraska. 83 [18,19] The plain language of § 28-105.01(3) does not establish a strict cutoff IQ score of 70; rather, it creates an evi

dentiary presumption in favor of finding intellectual disability when the defendant has an IQ score of 70 or below on a reli

ably administered test. Moreover, unlike the Florida Supreme Court in Hall , this court has not construed § 28-105.01 in

LOTTER Cite as 311 Neb. 878 a way that would prohibit those with an IQ score above 70 from presenting other evidence that would support a finding of intellectual disability. 84 Instead, as Vela recognized, Nebraska courts apply current clinical standards to the evidence in order to “reach [a] meaningful determination of whether a convicted defendant with an IQ in the low 70’s is a person with men

tal retardation.” 85 Moreover, Lotter’s 2018 diagnosis of intellectual disabil

ity was based on evidence provided to the expert regarding significant deficits in adaptive functioning that had existed throughout Lotter’s childhood and young adult life. In other words, Lotter has been aware of the objective facts relative to his deficits in adaptive functioning since his childhood. Similar evidence of deficits in adaptive functioning was adduced dur

ing Lotter’s trial more than 20 years ago. And we cannot ignore the fact that Lotter’s current postconviction counsel, during the records hearing in this case, expressly advised the district court: I want to make this clear for the record. There actually was an effort to raise an intellectual disability claim after Atkins came down in this case. I don’t know if [the State’s counsel] is familiar with those proceedings, but it occurred in the context of the federal habeas proceedings. And there was a request to remand to the district court for — or to the state court for an Atkins determination. That ball was dropped. There were no evaluations done at that time and . . . counsel abandoned the effort. As such, we agree with the district court that Lotter could have discovered, through the exercise of due diligence, the fac

tual predicate to support a constitutional claim of intellectual

fore agree that Lotter’s Atkins claim is not timely under § 29-3001(4)(b). And for the same reason, we also agree with the district court that Lotter’s Atkins claim is procedurally barred, because he failed to raise it in his first postconvic

tion motion after Atkins first announced the constitutional rule that those with an intellectual disability are ineligible for the death penalty. 87 (ii) Lotter’s Claim Not Timely Under § 29-3001(4)(d) Lotter argues that his Atkins claim is timely under § 29-3001(4)(d) because it was filed within 1 year after Moore I

was decided, and he contends Moore I recognized a new con

stitutional rule which applies retroactively. Under § 29-3001(4)(d), a postconviction claim is timely if filed within 1 year of the “date on which a constitutional

Jackson , 2020 Ohio 4015, 157 N.E.3d 240 (2020) (finding successive postconviction claim based on Atkins was procedurally and time barred because defendant did not raise claim on direct appeal in 2002, in first postconviction motion in 2003, or in federal habeas action in 2007, and did not exercise due diligence in discovering facts to support intellectual disability before 2019).
87 See Lotter, supra note 24, 278 Neb. at 477, 771 N.W.2d at 561 (postconviction claim of perjured testimony was procedurally barred because “Lotter fails to allege that this evidence was unavailable before any of the numerous challenges already made to his convictions and sentences”).

ment that his Atkins claim was timely under § 29-3001(4)(d) requires us to determine whether Moore I recognized a new constitutional right which has been applied retroactively to cases on collateral review. [20] As a general principle, the U.S. Supreme Court has said that state courts considering a matter on collateral review must give retroactive effect to new substantive rules of federal constitutional law. 88 Substantive rules of federal constitutional law include “‘rules forbidding criminal punishment of certain primary conduct but also rules prohibiting a certain category of punishment for a class of defendants because of their status or offense.’” 89 No one disputes that Atkins announced a new substan

tive rule of federal constitutional law when it held that the 8th and 14th Amendments to the U.S. Constitution categori

cally prohibit imposing the death penalty on the class of offenders who are intellectually disabled. 90 But neither the U.S. Supreme Court nor this court has previously considered whether Moore I announced a new substantive rule of consti

tutional law which must be applied retroactively to cases on collateral review.

LOTTER Cite as 311 Neb. 878 Most state and federal courts to have considered the ques

soned that Hall and Moore I merely adopted new procedures for ensuring states follow the constitutional rule announced in Atkins , and did not expand the class of individuals protected by Atkins ’ prohibition against the execution of individuals who are intellectually disabled. 93 For example, in Phillips v.

Atkins . The Sixth 95 and Eighth Circuits 96 have adopted similar reasoning with respect to Moore I

. [21] We likewise hold that neither Hall nor Moore I announced a new substantive rule of constitutional law that must be applied retroactively to cases on collateral review. Instead, both Hall and Moore I applied the substantive consti

tutional rule initially announced in Atkins and then refined the appropriate standards states should apply to determine whether an offender is intellectually disabled. Because Moore I did not recognize a new constitutional right which has been applied retroactively to cases on collateral review, that case did not trigger the 1-year limitations period under § 29-3001(4)(d). (iii) Lotter’s “Actual Innocence” Argument Next, Lotter argues that Nebraska’s rules governing proce

dural bars and time limitations in postconviction cases do not apply to his Atkins claim because, as someone who has been diagnosed as intellectually disabled, he is “actually innocent” of the death penalty. His argument rests on the U.S. Supreme Court opinion in Sawyer

. 97 Before addressing Lotter’s “actual innocence” argument under Sawyer , we provide an overview of the Supreme Court’s jurisprudence in this area. The Supreme Court’s “actual innocence” jurisprudence developed in the context of claims for federal habeas corpus relief. In federal habeas cases, the general rule is that “claims forfeited under state law may support federal habeas relief only if the prisoner demonstrates cause for the default and prejudice from the asserted error.” 98 But in 1986, the Court stated that “in an extraordinary case, where a constitutional violation has probably resulted in the conviction of one who is actually innocent, a federal habeas court may grant the writ

98 House v. Bell , 547 U.S. 518, 536, 126 S. Ct. 2064, 165 L. Ed. 2d 1 (2006).- 907 - Nebraska Supreme Court Advance Sheets 311 Nebraska Reports STATE v . LOTTER Cite as 311 Neb. 878 even in the absence of a showing of cause for the procedural default.” 99 This is sometimes referred to as the “fundamental miscarriage of justice” exception, and it “is grounded in the ‘equitable discretion’ of habeas courts to see that federal con

stitutional errors do not result in the incarceration of innocent persons.” 100 Over time, the Court has discussed at least three types of “actual innocence” claims, each with a different legal standard and purpose. 101 In Herrera v. Collins , 102 the Court considered whether a habeas petitioner may assert a “freestanding” constitutional claim of actual innocence. In that case, the petitioner sought habeas relief alleging that newly discovered evidence showed he was “actually innocent” of the crime for which he stood convicted. The Court found that the “fundamental miscarriage of justice exception” did not apply, since that exception is only available when the prisoner uses a claim of actual innocence to excuse a procedural error relating to an independent con

stitutional claim. 103 But Herrera nevertheless assumed without deciding that “in a capital case a truly persuasive demonstra

tion of ‘actual innocence’ made after trial would render the execution of a defendant unconstitutional, and warrant federal habeas relief if there were no state avenue open to process such a claim.” 104 Herrera noted the threshold showing for such a freestanding claim “would necessarily be extraordi

narily high.” 105

In Schlup v. Delo , 106 the Court discussed using a claim of actual innocence as a “gateway” to obtain review of a consti

tutional claim that is otherwise procedurally barred under state law. The Court explained that a Schlup- type actual innocence claim is “‘not itself a constitutional claim, but instead a gate

way through which a habeas petitioner must pass to have his [or her] otherwise barred constitutional claim considered on the merits.’” 107 Under Schlup , if the petitioner makes a “threshold showing” that he or she is actually innocent of the crime, the court may then consider whether the otherwise procedurally barred constitutional claim entitles the petitioner to federal habeas relief. 108 In Sawyer , the Court described a third type of actual inno

cence claim—a claim that a habeas petitioner is “‘actually innocent’ of the death penalty.” 109 A Sawyer -type actual inno

cence claim resembles the gateway actual innocence claim described in Schlup , as both are used to excuse a procedural default. But there is a critical difference: In a Sawyer -type claim, the petitioner alleges that the procedural default should be excused because he or she is actually innocent of the death penalty, rather than actually innocent of the crime itself. The Sawyer Court acknowledged that the “prototypical example” 110 of an actual innocence claim involves “the case where the State has convicted the wrong person of the crime,” and it recognized that “[i]t is more difficult to develop an analogous framework when dealing with a defendant who has been sentenced to death,” since “[t]he phrase ‘innocent of death’ is not a natural usage of those words . . . .” 111 But it nevertheless found that such a claim was permissible in

And in crafting the framework for actual innocence claims in the death penalty sentencing context, Sawyer focused on whether the petitioner was eligible for the death penalty, rather than whether the petitioner was innocent of the crime itself. Sawyer held that to demonstrate actual innocence of the death penalty, a petitioner “must show by clear and convincing evidence that, but for a constitutional error, no reasonable juror would have found the petitioner eli

gible for the death penalty under the applicable state law.” 112 If such a showing is made, the federal habeas court can consider the merits of the constitutional claim, despite a state proce

dural bar. Lotter correctly points out that Nebraska’s postconviction jurisprudence has addressed the type of freestanding “actual innocence” claim described in Herrera

. 113 And in 2016, we recognized that a Herrera -style claim of actual innocence “may be a sufficient allegation of a constitutional violation under the Nebraska Postconviction Act.” 114 But even in cases where we have discussed a Herrera -type actual innocence claim, we have not once found a postconviction defendant to have satisfied the “extraordinarily high” showing necessary for an evidentiary hearing on such a claim. 115 Lotter himself has previously attempted to raise such an actual innocence claim, without success. 116

LOTTER Cite as 311 Neb. 878 But in this case, Lotter is not asserting a freestanding Herrera -type actual innocence claim. Instead, he argues that “as a person with an intellectual disability, he is actually inno

cent of the death penalty and thus his claim is not subject to procedural default or time bars.” 117 In other words, Lotter is asking us to recognize a Sawyer -type claim of actual innocence and to allow him to proceed with his Atkins claim despite Nebraska’s time and procedural bar rules. In asking us to apply Sawyer to his postconviction motion, Lotter refers us to several federal cases in which habeas peti

tioners have raised a Sawyer -type actual innocence claim to argue they should be allowed to proceed on their procedurally barred Atkins claims because their intellectual disability ren

dered them ineligible for the death penalty under state law. 118 But as we explain, recognizing an actual innocence exception to Nebraska’s procedural and time bar rules is a policy deci

sion for the Legislature. Our opinion in State v. Hessler 119 is instructive. In Hessler , a defendant seeking postconviction relief urged us to recognize an exception to Nebraska’s procedural bar rules based on the U.S. Supreme Court’s decision in Martinez v. Ryan

. 120 Martinez held that a state procedural default will not bar a federal habeas court from considering a substan

tial claim of ineffective assistance of trial counsel if, in the initial-review collateral proceeding, there was no counsel or counsel in that proceeding was ineffective. 121 We declined to adopt the Martinez rule as part of our postconviction jurispru

dence, explaining: Martinez did not recognize a constitutional right to effective assistance of postconviction counsel. Based

cedural default in a federal habeas proceeding. Nothing in Martinez prevents state courts from enforcing procedural defaults in accordance with state law. 122 Emphasizing that the Nebraska Legislature has limited state postconviction relief to a single proceeding, and has expressly authorized courts to reject successive motions, 123 Hessler con
cluded that whether to allow successive postconviction motions based on the reasoning of Martinez was a matter of policy to “be addressed in the first instance to the Legislature.” 124 [22] We find our reasoning in Hessler instructive in respond

ing to Lotter’s request that we recognize a Sawyer -type actual innocence exception to Nebraska’s procedural and time bars. While Sawyer recognized a path for a federal habeas court to excuse a procedural default, it did not recognize a new consti

tutional rule. And we see nothing in the language of Sawyer , or in any subsequent Supreme Court decision, which requires state courts to apply the reasoning of Sawyer to excuse proce

dural defaults in postconviction cases, nor do we see anything in Sawyer which would prevent a state court from enforcing its procedural or time bar rules when presented with an Atkins claim on collateral review. Indeed, state courts have held that a postconviction defendant can waive an Atkins claim by fail

ing to follow the state’s applicable procedural rules. 125 And the expectation that state courts will enforce their procedural bar rules is the reason the Schlup and Sawyer rules were developed in the first instance. We decline Lotter’s invitation to import a Sawyer -type actual innocence claim into our state postconviction jurispru

. (iv) § 28-105.01 Does Not Exempt Atkins Claims From Procedural

and Time Bars in § 29-3001 Finally, Lotter argues that his Atkins claim is not subject to the procedural or time limitations in § 29-3001 “because the express language of . . . § 28-105.01(2) states that the death penalty shall not be imposed upon any person with an intellec

tual disability ‘ notwithstanding any other provision of law. ’” 126 In other words, Lotter contends that when a postconviction motion raises an Atkins claim, that claim is exempted from the procedural and time limitations in the Nebraska Postconviction Act by the statutory language in § 28-105.01(2). To the extent this argument has been preserved for appellate review, we find it to be without merit. [23] It is difficult to discern, from the record on appeal, whether this argument was presented to and passed upon by the district court. Generally, when the timeliness of a post

conviction motion is at issue, the defendant must raise all applicable arguments in the district court to preserve them for appellate review. 127 The face of Lotter’s fifth postconviction motion does not assert that the language of § 28-105.01(2)

LOTTER Cite as 311 Neb. 878 exempts an Atkins claim from the procedural and time bars set out in the Nebraska Postconviction Act. And we see no such argument presented during the records hearing in February 2020. But the district court’s order did briefly address, and reject, some sort of statutory argument based on the language of § 28-105.01(2), reasoning that the statute recognized only a “statutory claim, not a constitutional claim” that would be cognizable under the Nebraska Postconviction Act. Assuming without deciding that the district court was rejecting the same statutory argument Lotter now asserts on appeal, we reject it too. [24,25] To consider the meaning of § 28-105.01(2), we apply familiar principles. When construing a statute, a court must determine and give effect to the purpose and intent of the Legislature as ascertained from the entire language of the statute considered in its plain, ordinary, and popular sense. 128 Additionally, the rules of statutory interpretation require an appellate court to give effect to the entire language of a statute, and to reconcile different provisions of the statutes so they are consistent, harmonious, and sensible. 129 And in a previous case where we considered the meaning of the statutory definition of intellectual disability contained in § 28-105.01(3), we empha

sized the importance of considering “the scope of the remedy to which its terms apply and [giving] the statute such an inter

pretation as appears best calculated to effectuate the design of the legislative provisions.” 130 [26] The Legislature first enacted § 28-105.01(2) in 1998, 131 several years before Atkins announced the constitutional rule banning imposition of the death penalty on persons with an intellectual disability. As such, § 28-105.01(2) was not

. Rather, it was enacted to establish a statutory right in Nebraska prohibiting imposition of the death penalty on persons who are intellectually disabled. And to enforce that statutory right, the Legislature enacted a specific statutory procedure to allow a defendant facing the death penalty to file a verified motion and request a hearing to determine intellectual disability, before any sentencing determination is made. 132 The 1998 statutory scheme also provided a procedure for those who had already been sentenced to death when the new statutory right was recognized: Within one hundred twenty days after the effective date of this act, a convicted person sentenced to the penalty of death prior to the effective date of this act may bring a verified motion in the district court which imposed such sentence requesting a ruling that the penalty of death be precluded under subsection (2) of this section and that the sentence be vacated. 133 Lotter had been sentenced to death when this statute took effect, but he did not file a motion under this provision. In 2013, the Legislature removed this provision from § 28-105.01 altogether, 134 presumably because the 120-day window had long since expired. Currently, the only enforcement procedures available to defendants are those set out in § 28-105.01(4), and those procedures apply only to defendants who have not yet been sentenced to death. As such, Lotter’s opportunity to request a hearing to enforce the statutory right not to have the death penalty imposed has long since passed. Having waived his opportunity to pursue the statutory enforcement procedure previously available to him, Lotter

ity under Atkins , and he attempts to use language from § 28-105.01(2) to avoid the procedural and time bars under the Nebraska Postconviction Act. Specifically, Lotter argues that the phrase “notwithstanding any other provision of law” in § 28-105.01(2) should be construed as a Legislative “mandate[]” 135 that “renders moot” 136 the procedural and time limits which otherwise govern postconviction motions. We reject Lotter’s proposed construction. [27] As a general principle of statutory construction, courts have held that use of the phrase “notwithstanding any other provision of law” in a statute signals legislative intent to over

ride other provisions of law that conflict with the statute. 137 We agree with this general principle, 138 but we see no conflict between the statutory rights and enforcement procedures set out in § 28-105.01 and the procedural and time limitations set out in the Nebraska Postconviction Act.

LOTTER Cite as 311 Neb. 878 Lotter’s argument conflates the statutory right recognized in § 28-105.01(2) with the constitutional right recognized in Atkins . But the statutory right is enforced presentence through the procedures set out in § 28-105.01(4), not through the Nebraska Postconviction Act, which exists only to remedy prejudicial constitutional violations that render a judgment void or voidable. 139 Simply put, there is no conflict between the provisions of § 28-105.01(2) and the provisions of § 29-3001(4), because they address separate legal claims and provide separate legal remedies. The former applies to statutory claims of intellectual disability raised in a verified motion prior to the imposition of any sentence, and the latter applies to all constitutional claims raised in a verified postconviction motion by prisoners in cus

tody seeking to vacate or set aside their sentence. [28] We conclude the phrase “notwithstanding any other provision of law” in § 28-105.01(2) neither impacts nor over

rides the procedural and time limitations applicable to post

conviction motions under the Nebraska Postconviction Act. Lotter’s argument to the contrary is meritless. (e) Conclusion on Lotter’s Atkins Claim For the foregoing reasons, we agree with the district court that Lotter’s Atkins claim is both procedurally barred and time barred.
3. Lotter’s L.B. 268 Claim Lotter also argues he was entitled to an evidentiary hear

ing on his other postconviction claim, which asserted that the passage, and subsequent repeal by public referendum, of L.B. 268 140 had the effect of vacating, and then reinstating, his death sentences. The district court properly denied relief on this claim without an evidentiary hearing.

140 See 2015 Neb. Laws, L.B. 268.- 917 - Nebraska Supreme Court Advance Sheets 311 Nebraska Reports STATE v . LOTTER Cite as 311 Neb. 878 We described the procedural history of L.B. 268 in State v. Jenkins : 141 In May 2015, the Nebraska Legislature passed 2015 Neb. Laws, L.B. 268,—which abolished the death penalty in Nebraska—and then overrode the Governor’s veto of the bill. The Legislature adjourned sine die on May 29. Because L.B. 268 did not contain an emergency clause, it was to take effect on August 30. Following the passage of L.B. 268, opponents of the bill sponsored a referendum petition to repeal it. On August 26, 2015, the opponents filed with the Nebraska Secretary of State signatures of approximately 166,000 Nebraskans in support of the referendum. On October 16, the Secretary of State certified the validity of suf

ficient signatures. Enough signatures were verified to suspend the operation of L.B. 268 until the referendum was approved or rejected by the electors at the upcom

ing election. During the November 2016 election, the referendum passed and L.B. 268 was repealed, that is, in the language of the constitution, the act of the Legislature was “reject[ed].” [29,30] All of Lotter’s constitutional claims relating to L.B. 268 are premised on the theory that the legislation went into effect on August 30, 2015, and commuted his death sentences to life in prison, and that thereafter, the successful public referendum resulted in reimposition of his death sen

tences. But as the district court correctly recognized, we have rejected that theory as legally flawed in three prior cases— Jenkins , 142 State v. Mata , 143 and State v. Torres

. 144 In Jenkins , we explained that L.B. 268 never actually went into effect,

islative act is suspended so long as the verification and cer

tification process ultimately determines that the petition had the required number of valid signatures.” 145 And we expressly held in Jenkins , Mata , and Torres that because L.B. 268 was suspended and never went into effect, any death sentences in effect at the time were unchanged. 146 On appeal, Lotter acknowledges that our decisions in Jenkins , Mata , and Torres are “adverse[]” 147 to his central premise that L.B. 268 vacated his death sentences and the successful public referendum reinstated them. Lotter’s appellate brief summarily states that all three cases “were wrongly decided and should be overruled,” 148 but he presents no argument in support, and we see no principled reason to revisit our settled jurisprudence on the issue. Because all of Lotter’s L.B. 268 claims are premised on the meritless theory that L.B. 268 vacated or changed his death sentences, the district court properly denied relief on these claims without conducting an evidentiary hearing. 149
