MATA Cite as 304 Neb. 326 State of Nebraska, appellee, v. R aymond M ata, Jr., appellant. ___ N.W.2d ___ Filed October 25, 2019. No. S-18-740. 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 demonstrate 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 question of law which is reviewed independently of the lower court’s ruling. 3. Constitutional Law: Trial. Inherently prejudicial practices, like shack- ling, are constitutionally forbidden during the guilt phase of a trial unless the use is justified by an essential state interest specific to each trial. 4. Postconviction: Appeal and Error. A motion for postconviction relief cannot be used to secure review of issues which were or could have been litigated on direct appeal. 5. Limitations of Actions. The doctrine of equitable tolling permits a court to excuse a party’s failure to comply with the statute of limitations where, because of disability, irremediable lack of information, or other circumstances beyond his or her control, the plaintiff cannot be expected to file suit on time. 6. Statutes: Initiative and Referendum. Upon the filing of a referendum petition appearing to have a sufficient number of signatures, operation of the legislative act is suspended so long as the verification and certi- fication process ultimately determines that the petition had the required number of valid signatures. 7.

MATA Cite as 304 Neb. 326 and after denial of an initial motion for postconviction relief (Mata III).3 Mata argues the district court erred in denying his constitutional claims that he was made to wear shackles in front of the jury during jury selection, overruling and find- ing untimely his claims that the sentencing scheme requiring a judge to make factual findings to impose the death pen- alty was unconstitutional, and overruling and finding untimely his claims that his constitutional rights were violated by the Legislature’s passing a bill repealing the death penalty but a public referendum reimposing it. For the reasons stated herein, we affirm. BACKGROUND Mata was found guilty of first degree premeditated murder, first degree felony murder, and kidnapping in association with the death of 3-year-old Adam Gomez. In Mata I,4 we explained the evidence adduced at trial showed Adam was the son of Patricia Gomez and Robert Billie. Patricia, Billie, and Adam lived together until September 1998, when Patricia and Billie ended their relationship and Billie moved out. Shortly thereaf- ter, Mata and Patricia began dating, and Mata moved in with Patricia and Adam in October or November. Patricia later told police that although Mata did not treat Adam badly, Mata con- sistently expressed resentment of Adam. Mata moved out on February 10, 1999, and moved in with his sister. That night, Patricia and Billie had sexual relations. On February 11, Patricia obtained a restraining order against Mata. However, Patricia continued to see Mata and they had sexual relations on February 14. Later in February 1999, Patricia found out she was pregnant. Mata became aware of Patricia and Billie’s sexual encounter and heard that the child had been conceived between February 3 State v. Mata, 280 Neb. 849, 790 N.W.2d 716 (2010), disapproved, State v. Robertson, 294 Neb. 29, 881 N.W.2d 864 (2016). 4 Mata I, supra note 1. - 329 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 7 and 10. Mata had separate confrontations with both Patricia and Billie about their relationship. On March 11, 1999, Mata discovered that Patricia, Billie, and Adam attended a doctor’s appointment for Adam together. That day, Mata unsuccessfully attempted to have Patricia come to his sister’s house to visit him. When Patricia would not come to him, Mata went to Patricia. At her residence, Adam was watching television and Mata sent him to bed. Patricia testified she fell asleep while Mata watched television. Patricia said that when she woke up, Mata and Adam were gone, as was the sleeping bag that Adam had been using as a blanket. Mata denied knowing where Adam was when Patricia called at 3:37 a.m. Mata came back to Patricia’s house and told Patricia that Adam was likely with her mother or Billie. In subsequent searches of Mata’s sister’s residence, police found Adam’s sleeping bag and clothing Adam had been wearing in a bag in the dumpster behind the residence. The bag also contained trash identified as being from the resi- dence, including a towel and a boning knife that Mata’s sister denied throwing away. In the residence, police found human remains in the basement room occupied by Mata. Hidden in the ceiling was a package wrapped in plastic and duct tape which contained a crushed human skull. The skull was fractured in several places by blunt force trauma that had occurred at or near the time of death. The head had been sev- ered from the body by a sharp object at or near the time of death. In the kitchen refrigerator, police found a foil-wrapped package of human flesh. Mata’s fingerprint was found on the foil. Human remains were also found on a toilet plunger and were found to be clogging the sewer line from the residence. Human flesh, both cooked and raw, was found in a bowl of dog food and in a bag of dog food. Human bone fragments were recovered from the digestive tract of Mata’s sister’s dog. All of the recovered remains were later identified by DNA analysis as those of Adam. Adam’s blood was also found on Mata’s boots. - 330 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 After Mata was convicted, he was sentenced to life impris- onment for kidnapping and a three-judge panel sentenced him to death for first degree premeditated murder, finding the exis- tence of an aggravating circumstance under Neb. Rev. Stat. § 29-2523(1)(d) (Cum. Supp. 2002). In Mata I, we affirmed these convictions and the life imprisonment sentence for kid- napping. Based upon Ring v. Arizona,5 which was decided after the sentencing, we vacated the death sentence and remanded the cause with directions for a new penalty phase hearing and resentencing on the first degree premeditated murder convic- tion, requiring the jury to determine the existence of aggravat- ing circumstances.6 On remand, the jury unanimously found the existence of the aggravating circumstance of exceptional depravity. A three- judge panel then heard evidence on mitigating circumstances and sentencing disproportionality. The panel found no statu- tory mitigating circumstances, considered five nonstatutory mitigating circumstances, and concluded the mitigating fac- tors did not approach or exceed the weight of the exceptional depravity finding. The panel determined the penalty was not excessive or disproportionate to the penalty imposed in similar cases and again sentenced Mata to death on the first degree premeditated murder conviction. In Mata II, issued February 8, 2008, we affirmed the impo- sition of Mata’s death sentence. However, we determined that electrocution, as a means of carrying out that sentence, was cruel and unusual punishment in violation of Neb. Const. art. I, § 9, and issued an indefinite stay of Mata’s execution.7 Mata filed a petition for certiorari with the U.S. Supreme Court. On October 6, the Supreme Court denied Mata’s petition. On July 2, 2009, Mata filed a pro se motion for postconvic- tion relief. At a preliminary hearing in October to consider 5 Ring v. Arizona, 536 U.S. 584, 122 S. Ct. 2428, 153 L. Ed. 2d 556 (2002). 6 Mata I, supra note 1. 7 Mata II, supra note 2. - 331 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 whether to grant a request of counsel and an evidentiary hear- ing, Mata argued that he believed an evidentiary hearing would be premature because he was not “‘ready’” and wished for the court to first consider the appointment of counsel who he hoped could assist him in evaluating the record and amend- ing the motion before the merits would be determined.8 Mata explained that he filed the motion for postconviction relief without first fully reviewing the record, because he needed to toll the 1-year statute of limitations for filing an applica- tion for a writ of habeas corpus in federal court. He claimed that our indefinite stay of his execution had placed him in a legal “‘limbo’” which prevented him from filing a habeas action within a year from the final judgment.9 Mata stated he would like an opportunity to amend his motion, with or with- out counsel. In a single final order, the district court denied both an evidentiary hearing and Mata’s request for appointment of counsel. The court did not specifically determine whether the motion for postconviction relief presented any justiciable issue which would entitle Mata to appointment of counsel. Instead, the court found that the files and records affirmatively showed that Mata was entitled to no relief based on the allegations in his motion. In Mata III, we found it was an abuse of the district court’s discretion to deny Mata leave to amend his motion for post- conviction relief, reversed the district court’s judgment, and remanded the cause with directions to appoint Mata counsel and grant him leave to amend his motion. The mandate in Mata III was issued on March 8, 2011, and Mata was appointed postconviction counsel on March 15. 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. Within L.B. 8 Mata III, supra note 3, 280 Neb. at 851, 790 N.W.2d at 717. 9 Id. at 851, 790 N.W.2d at 718. - 332 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 268, the Legislature provided that “in any criminal proceeding in which the death penalty has been imposed but not carried out prior to the effective date of this act, such penalty shall be changed to life imprisonment.” The Legislature adjourned sine die on May 29. Because L.B. 268 did not contain an emer- gency clause, it was to take effect on August 30.10 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 certi- fied the validity of sufficient 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 upcoming 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].’”11 On December 4, 2017, Mata filed his first amended motion for postconviction relief, and on March 16, 2018, he filed a second amended motion. The district court denied Mata’s second amended motion for postconviction relief without an evidentiary hearing. Mata timely appealed. ASSIGNMENTS OF ERROR On appeal, Mata assigns, consolidated and restated, that the district court erred in (1) denying the claim that his constitu- tional rights were violated by being shackled during jury selec- tion, because it could have been, and was, brought and decided on direct appeal; (2) denying and finding untimely Mata’s claims that his Sixth Amendment rights were violated by hav- ing a panel of judges find mitigating circumstances and weigh those circumstances against the jury’s finding of aggravating 10 See State v. Jenkins, 303 Neb. 676, 931 N.W.2d 851 (2019). 11 See id. at 706, 931 N.W.2d at 877. See, also, Neb. Const. art. III, § 3. - 333 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 circumstances; (3) denying and finding untimely Mata’s claims that the referendum process and result amounted to an imper- missible bill of attainder, cruel and unusual punishment, and violations of his due process rights by imposing a death sen- tence on Mata after it was changed to life imprisonment by L.B. 268; and (4) denying and finding untimely Mata’s claims that the process of the referendum and its supporting campaign were an improper exercise violating constitutionally recog- nized separation of powers. 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.12 [2] Whether a claim raised in a postconviction proceeding is procedurally barred is a question of law which is reviewed independently of the lower court’s ruling.13 ANALYSIS Use of Shackles During Jury Selection Mata first assigns that the district court erred in deny- ing the claim that his constitutional rights were violated by being shackled during jury selection. On this assignment, Mata alleges he was required to walk with shackles into the court- room, in front of the jury to be selected, before being seated. Mata argues the district court incorrectly determined this issue could have been, and was, brought and decided on direct appeal, because Deck v. Missouri14 was not decided until after Mata’s first appeal. 12 State v. Allen, 301 Neb. 560, 919 N.W.2d 500 (2018). 13 State v. Tyler, 301 Neb. 365, 918 N.W.2d 306 (2018). 14 Deck v. Missouri, 544 U.S. 622, 125 S. Ct. 2007, 161 L. Ed. 2d 953 (2005). - 334 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 [3] This argument is without merit. Deck did not establish a new rule for the use of shackles throughout a trial. Deck extended the existing holding detailed in Holbrook v. Flynn15 that inherently prejudicial practices, like shackling, are consti- tutionally forbidden during the guilt phase of a trial unless the use is “justified by an essential state interest specific to each trial.” Deck clarified that this requirement also applies to the penalty phase.16 [4] In Mata I, we addressed Mata’s claim of a constitutional violation of his rights due to his being shackled during jury selection and specifically analyzed it under the requirement detailed in Holbrook.17 In his current appeal, Mata makes no new arguments based upon Deck’s extension of that require- ment. Instead, Mata seeks to relitigate his claims which were rejected on direct appeal, because Deck was decided after Mata I and restated Holbrook’s holding. A motion for post- conviction relief cannot be used to secure review of issues which were or could have been litigated on direct appeal.18 Accordingly, this assignment is procedurally barred. Use of Panel of Judges in M ata’s Sentencing Mata next assigns the district court erred in denying and finding untimely his claims challenging the use of the panel of judges to consider mitigating circumstances and weigh those circumstances against the jury’s finding of aggravating circumstances. In considering this constitutional challenge to Nebraska’s capital sentencing scheme, we must first determine whether these claims are time barred under Neb. Rev. Stat. § 29-3001(4) (Reissue 2016). 15 Holbrook v. Flynn, 475 U.S. 560, 569, 106 S. Ct. 1340, 89 L. Ed. 2d 525 (1986). 16 Deck, supra note 14. 17 Mata I, supra note 1. 18 Allen, supra note 12. - 335 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 The Nebraska Postconviction Act contains a 1-year time limit for filing a verified motion for postconviction relief, which runs from one of four triggering events or August 27, 2011, whichever is later.19 The triggering events are: (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[.]20 Mata first made his postconviction claims challenging the use of a panel of judges to find and consider mitigating circumstances in his initial amended postconviction motion filed December 2017. Mata argues his claims are not time barred, because the U.S. Supreme Court in Hurst v. Florida 21 provided newly recognized constitutional requirements for capital sentencing schemes. Although Hurst was decided in January 2016,22 Mata and amici curiae argue that equitable tolling should apply because the passage of L.B. 268 and its repeal through public referendum created uncertainty as to Mata’s sentence. 19 State v. Harrison, 293 Neb. 1000, 881 N.W.2d 860 (2016). 20 § 29-3001(4). 21 Hurst v. Florida, ___ U.S. ___, 136 S. Ct. 616, 193 L. Ed. 2d 504 (2016). 22 Id. - 336 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 [5] The doctrine of equitable tolling permits a court to excuse a party’s failure to comply with the statute of limitations where, because of disability, irremediable lack of information, or other circumstances beyond his or her control, the plaintiff cannot be expected to file suit on time.23 However, to date, we have not determined whether the doctrine of equitable tolling applies to postconviction actions brought under § 29-3001.24 In this matter, we again need not make the determination as to whether equitable tolling applies to postconviction actions. In order for Hurst to be pertinent, the holding must have rec- ognized a constitutional claim and that the newly recognized right is applicable retroactively to cases on postconviction col- lateral review. In State v. Lotter,25 we considered the question of whether Hurst was a triggering event under § 29-3001(4) to chal- lenges to Nebraska’s capital sentencing scheme. In Lotter, the defendant filed a motion for postconviction relief alleg- ing Nebraska’s capital sentencing scheme was unconstitutional in light of Hurst and within a year of the Hurst decision. In finding this claim time barred, we determined that the Hurst decision did not initially recognize a constitutional claim and set forth a new rule of law for sentencing. We explained Hurst merely applied the constitutional requirement recognized in Ring 26 that “capital defendants are entitled to a jury determi- nation of any fact that would increase the possible maximum punishment,” which was a holding that utilized a rule from Apprendi v. New Jersey 27 that “‘“[i]t is unconstitutional for a legislature to remove from the jury the assessment of facts that 23 State v. Conn, 300 Neb. 391, 914 N.W.2d 440 (2018). 24 See, id.; State v. Huggins, 291 Neb. 443, 866 N.W.2d 80 (2015). 25 State v. Lotter, 301 Neb. 125, 917 N.W.2d 850 (2018), cert. denied ___ U.S. ___, 139 S. Ct. 2716, ___ L. Ed. 2d ___ (2019). 26 Ring, supra note 5. 27 Apprendi v. New Jersey, 530 U.S. 466, 120 S. Ct. 2348, 147 L. Ed. 2d 435 (2000). - 337 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 increase the prescribed range of penalties to which a criminal defendant is exposed.”’”28 In Lotter, we specifically addressed the argument Mata now raises that Hurst expanded on Ring and Apprendi and announced a new requirement that a jury must find and con- sider mitigating circumstances instead of a panel of judges. We stated: Most federal and state courts agree that Hurst did not hold a jury must find beyond a reasonable doubt that the aggravating factors outweigh the mitigating circumstances. The 10th Circuit aptly observed: “[T]he Supreme Court’s holding in Hurst only referenced the [finding of aggravating circumstances] . . . . The Court thus did not address whether the second of the required findings—that mitigating circumstances do not out- weigh the aggravating circumstances—is also subject to Apprendi’s rule.” . . . The plain language of Hurst reveals no holding that a jury must find beyond a rea- sonable doubt that the aggravating factors outweigh the mitigating circumstances. And this court has previously concluded that neither Apprendi nor Ring require[s] that the determination of mitigating circumstances, the bal- ancing function, or the proportionality review be under- taken by a jury.29 We find no reason to depart from our determination in Lotter that the Hurst opinion merely applied previously recog- nized constitutional requirements to Florida’s sentencing stat- ute and that it did not extend the holding in Ring and Apprendi to finding and considering mitigating circumstances in capital sentencing schemes. As such, Hurst did not create a trigger- ing event under § 29-3001(4) and Mata’s claims concerning Nebraska’s sentencing scheme are untimely and procedur- ally barred. 28 Lotter, supra note 25, 301 Neb. at 129, 917 N.W.2d at 855. 29 Id. at 144-45, 917 N.W.2d at 863-64. - 338 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 L.B. 268 and Public R eferendum Mata assigns that his constitutional rights against cruel and unusual punishment were violated and that he was deprived due process of law by L.B. 268 and its repeal by public ref- erendum, which constituted an impermissible bill of attainder. Central to all three constitutional claims is the proposition that L.B. 268 changed his sentence to life imprisonment and the public referendum changed it back to death. Contrary to this proposition, however, L.B. 268 never went into effect. L.B. 268 was passed in May 2015 and was set to take effect on August 30.30 On August 26, opponents filed with the Nebraska Secretary of State approximately 166,000 signatures in support of a referendum.31 Under the Nebraska Constitution, when a referendum is invoked as to any act “by petition signed by not less than ten percent of the registered voters . . . , it shall suspend the taking effect of such act” until a vote on the referendum.32 Therefore, L.B. 268 was suspended 4 days before the effective date. Mata and amici curiae argue a suspension under article III, § 3, of the Nebraska Constitution applies only once the Secretary of State determines the validity, sufficiency, and count of the petition’s signatures and determines whether con- stitutional and statutory requirements have been met. In the instant case, the Secretary of State did not certify the validity of sufficient signatures until October 16, 2015. Under Mata and amici curiae’s view, L.B. 268 was not suspended until the October 16 certification and was in effect from its August 30 effective date until this certification. We addressed this argument in State v. Jenkins.33 In that case, Nikko Jenkins, who was convicted but not sentenced to death prior to the passage of L.B. 268, argued L.B. 268 and its 30 See Jenkins, supra note 10. 31 See id. 32 Neb. Const. art. III, § 3. 33 Jenkins, supra note 10. - 339 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 subsequent repeal amounted to a violation of the Ex Post Facto Clauses of the U.S. and Nebraska Constitutions. In denying this claim, we rejected the notion that signatures must be veri- fied and certified before an act’s operation will be suspended. We reasoned: Jenkins’ notion conflicts with several fundamental principles. The power of referendum must be liberally construed to promote the democratic process. The power is one which the courts are zealous to preserve to the full- est tenable measure of spirit as well as letter. The consti- tutional provisions with respect to the right of referendum reserved to the people should be construed to make effec- tive the powers reserved. Stated another way, the provi- sions authorizing the referendum should be construed in such a manner that the legislative power reserved in the people is effectual. The right of referendum should not be circumscribed by narrow and strict interpretation of the statutes pertaining to its exercise. Jenkins’ contention—that suspension cannot occur until a sufficient number of signatures are certified— would make ineffectual the people’s power to suspend an act’s operation. Whether an act went into effect, and for how long, would depend upon how quickly the Secretary of State and election officials counted and verified sig- natures. Jenkins’ argument demonstrates the absurdity of such a view. Because the Secretary of State was unable to confirm that a sufficient number of voters signed the petitions until October 16, 2015, Jenkins contends that L.B. 268 went into effect on August 30, thereby changing all death sentences to life imprisonment and changing the status of any defendant facing a potential death sentence to a defendant facing a maximum sentence of life impris- onment. Such an interpretation would defeat the purpose of this referendum—to preserve the death penalty. Our constitution demands that the power of referendum not be impaired by ministerial tasks appurtenant to the process. - 340 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 Having produced the signatures necessary to suspend the act’s operation, the people were entitled to implementa- tion of their will.34 [6] As in Jenkins, we conclude that upon the filing of a ref- erendum petition appearing to have a sufficient number of sig- natures, operation of the legislative act is suspended so long as the verification and certification process ultimately determines that the petition had the required number of valid signatures.35 Accordingly, L.B. 268 was suspended on August 26, 2015, 4 days prior to the effective date by the filing of the referendum petition and necessary signatures. Mata’s cruel and unusual punishment, due process, and bill of attainder claims which assert that L.B. 268 changed his sentence to life imprisonment and that the repeal of L.B. 268 resentenced him to death fail, because L.B. 268 was suspended and no such changes in his sentence occurred. It appears Mata may also be claiming he was subjected to cruel and unusual punishment by the political debate on the death penalty, the possibility that his sentence would be changed by L.B. 268 regardless of whether it went into effect, and the threat of his sentence of death remaining through the repeal of L.B. 268. However, the entirety of Mata’s analysis and supporting authority presumes his sentence was changed by L.B. 268, which, as determined above, did not occur, because it was suspended prior to its effective date. Mata pro- vides no argument or authority for the proposition that a cruel and unusual punishment violation could occur from a stated possibility of a change in a defendant’s sentence and the public debate on that issue, and we find none. Additionally, Mata’s assertion that public debate and the potential effect of a suspended bill is enough to warrant a cruel and unusual punishment finding is flawed. Assuming without deciding that emotional or psychological harm alone 34 Id. at 709-10, 931 N.W.2d at 878-79. 35 Jenkins, supra note 10. - 341 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 is to be considered pain in an Eighth Amendment analysis, the U.S. Supreme Court has repeatedly held that because some risk of pain is inherent in any method of execution, the Constitution does not require the avoidance of all risk of pain.36 “‘The Eighth Amendment’s prohibition of “cruel and unusual” punishments necessarily excludes from constitutional recognition de minimis uses of physical force, provided that the use of force is not of a sort repugnant to the conscience of mankind.’”37 If the potential for a modification in a defendant’s convic- tion or sentence were sufficient, any defendant convicted and sentenced for violating a law would be eligible for relief every time a change in that law were contemplated by the Legislature, contemplated by a public referendum, vetoed by the Governor, or subjected to public debate. Moreover, it would open the door to a cruel and unusual challenge follow- ing every case where an appeal of a conviction or sentence is granted, whether successful or unsuccessful, in that the appeal process would also provide a possibility for a change in the party’s conviction or sentence. While we acknowledge the potential for modification of a defendant’s conviction or sen- tence is likely to affect that defendant, this potential does not rise to the level of unnecessary and wanton infliction of pain necessary for a determination of cruel and unusual punish- ment.38 Instead, they are necessary aspects of our democratic system which demands the examination and reexamination of its laws and participation of the electorate through political 36 Bucklew v.

MATA Cite as 304 Neb. 326 debate. Accordingly, Mata was not subjected to cruel and unusual punishment by the political debate on the death pen- alty, the possibility that his sentence would be changed by L.B. 268, and the threat of his sentence of death remaining through the repeal of L.B. 268. Separation of Powers Mata next challenges the process involved in the repeal of L.B. 268 through the public referendum. To the extent Mata’s claims under this assignment require that L.B. 268 went into effect prior to being suspended by the referendum process, those claims are without merit as described in the previ- ous section.39 On Mata’s remaining claims under this assignment, Mata asserts the Governor and State Treasurer impermissibly orga- nized and contributed to a group which opposed L.B. 268 and worked toward its repeal through the public referendum, solicited money for the opposition group, and took on leader- ship within the opposition group. Mata seems to make claims of due process and cruel and unusual punishment violations derived from separation of powers requirements under the Nebraska Constitution. However, while Mata states that the participation of the Governor and State Treasurer in the proc­ ess of the referendum violated his due process rights and rights against cruel and unusual punishment, it is unclear on what basis Mata is alleging such violations occurred. Instead, Mata’s argument exclusively centers on how the Governor’s and State Treasurer’s actions supporting and participating in the referendum violated the constitutional separation of powers requirements and that such violations invalidated the referendum. Mata relies on two provisions under the Nebraska Constitution: Neb. Const. art. III, § 1, and Neb. Const. art. II, § 1. Article III, § 1, provides: 39 See Jenkins, supra note 10. - 343 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 The legislative authority of the state shall be vested in a Legislature consisting of one chamber. The people reserve for themselves the power to propose laws and amendments to the Constitution and to enact or reject the same at the polls, independent of the Legislature, which power shall be called the power of initiative. The people also reserve power at their own option to approve or reject at the polls any act, item, section, or part of any act passed by the Legislature, which power shall be called the power of referendum. Article II, § 1, provides: The powers of the government of this state are divided into three distinct departments, the legislative, executive, and judicial, and no person or collection of persons being one of these departments shall exercise any power prop- erly belonging to either of the others except as expressly directed or permitted in this Constitution. Mata contends these provisions establish that legislative authority is vested solely within the Legislature and the peo- ple through the referendum process unless expressly directed or permitted under the Constitution. Mata argues that this means members of the executive branch, such as the Governor and State Treasurer, are prohibited from initiating, participat- ing, instructing, and actively supporting legislative initiatives through a referendum or organizing, participating, instructing, and actively supporting groups to do the same. Without determining the constitutional appropriateness of the Governor’s and State Treasurer’s participation in the ref- erendum process, Mata’s separation of powers claims fail because the result of the referendum is not invalidated even if such actions were constitutionally improper as alleged. Such a determination is in line with cases where we have previously found dual-service violations.40 In those cases, the remedy 40 See, State ex rel. Stenberg v. Murphy, 247 Neb. 358, 527 N.W.2d 185 (1995); State ex rel. Spire v. Conway, 238 Neb. 766, 472 N.W.2d 403 (1991). - 344 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 was not abandonment of any action in which the violating party participated but was to remove the party from the violat- ing position.41 In addition, Mata asserts the Governor and State Treasurer acted improperly but does not allege that the Governor’s and State Treasurer’s participation influenced the referendum, that the referendum would have been frustrated if they had not participated, that votes were changed due to their par- ticipation, or how the referendum and its results are impos- sibly linked to the alleged inappropriate participation. At oral argument, Mata’s counsel admitted that he was unsure what impact the Governor or the State Treasurer had on the refer- endum process. In contrast, the facts which Mata did allege demonstrate the repeal of L.B. 268 did not occur solely at the Governor’s and State Treasurer’s direction. The referendum process was a public process which required a petition with the signatures of more than 10 percent of the registered voters for its initiation, it required public debate and deliberation, and it required a public vote. [7] In a postconviction proceeding, an evidentiary hearing is not required when the motion does not contain factual allega- tions which, if proved, constitute an infringement of the mov- ant’s constitutional rights.42 Mata did not allege facts sufficient to invalidate the repeal of L.B. 268 due to separation of powers violations, and there- fore, Mata’s claims under this assignment fail to establish a denial or infringement on his rights so as to render his sentence void or voidable. Accordingly, Mata’s separation of powers claims fail. CONCLUSION For the reasons stated above, Mata is not entitled to post- conviction relief for his constitutional claims involving being 41 See id. 42 Allen, supra note 12. - 345 - Nebraska Supreme Court A dvance Sheets 304 Nebraska R eports STATE v. MATA Cite as 304 Neb. 326 shackled during jury selection, his having a panel of judges find and weigh mitigating circumstances, the effect of L.B. 268 and the referendum rejecting it, and the Governor’s and State Treasurer’s participation in the referendum proc­ ess. Accordingly, the district court did not err in denying Mata’s motion for postconviction relief without an eviden- tiary hearing. A ffirmed. Freudenberg, J., not participating.
