                                        State of Nebraska, appellee, v.
                                          Jack E. H arris, appellant.
                                                    ___ N.W.2d ___

                                          Filed April 7, 2017.     No. S-16-283.

                1.	 Postconviction: Evidence: Appeal and Error. In reviewing a trial
                     court’s factual findings following an evidentiary hearing in a postcon-
                     viction case, an appellate court will uphold those findings unless they
                     are clearly erroneous.
                2.	 Appeal and Error. An appellate court independently reviews questions
                     of law decided by a lower court.
                3.	 Constitutional Law. The determination of constitutional requirements
                     presents a question of law.
                4.	 Effectiveness of Counsel: Appeal and Error. When a claim of inef-
                     fective assistance of counsel presents a mixed question of law and fact,
                     an appellate court reviews the lower court’s factual findings for clear
                     error but independently determines whether those facts show counsel’s
                     performance was deficient and prejudiced the defendant.
                5.	 Pretrial Procedure: Prosecuting Attorneys: Evidence. Under Brady
                     v. Maryland, 373 U.S. 83, 83 S. Ct. 1194, 10 L. Ed. 2d 215 (1963), the
                     prosecution has a duty to disclose all favorable evidence to a criminal
                     defendant prior to trial.
                6.	 Evidence: Impeachment: Words and Phrases. Favorable evidence
                     includes both exculpatory and impeachment evidence.
                7.	 Prosecuting Attorneys: Evidence: Due Process. Suppression by the
                     prosecution of evidence favorable to an accused upon request violates
                     due process where the evidence is material either to guilt or to punish-
                     ment, irrespective of the good faith or bad faith of the prosecution.
                 8.	 ____: ____: ____. The Due Process Clause requires the prosecution to
                     disclose favorable material evidence even if a defense counsel did not
                     request it.
                9.	 Prosecuting Attorneys: Evidence: Due Process: Police Officers and
                     Sheriffs. A prosecutor has a due process duty to learn of favorable

       material evidence known to others acting on the government’s behalf
       in a case. Thus, the State’s duty to disclose favorable material evidence
       exists even if the evidence was known only to police investigators and
       not to the prosecutor.
10.	   Prosecuting Attorneys: Evidence: Verdicts. The prosecution’s undis-
       closed evidence must be material either to guilt or to punishment, and
       the prosecution’s suppression of favorable evidence violates a defend­
       ant’s due process right to a fair trial only if the suppressed evidence is
       sufficiently significant to undermine confidence in the verdict.
11.	   Prosecuting Attorneys: Evidence: Judgments: Words and Phrases.
       For all claims of prosecutorial suppression of favorable material evi-
       dence, the evidence is material only if there is a reasonable probability
       that, had the evidence been disclosed to the defense, the result of the
       proceeding would have been different.
12.	   Trial: Evidence. Under Kyles v. Whitley, 514 U.S. 419, 115 S. Ct. 1555,
       131 L. Ed. 2d 490 (1995), the touchstone of a reasonable probability
       of a different result is not a sufficiency of the evidence test and does
       not require a defendant to show that an acquittal was more likely than
       not with the suppressed evidence. Instead, the question is whether the
       defend­ant received a fair trial without the evidence.
13.	   Judgments: Evidence: Due Process. When the State has suppressed
       more than one item of favorable material evidence, a court must con-
       sider, in addition to the three primary components of a due process
       violation contemplated by Brady v. Maryland, 373 U.S. 83, 83 S. Ct.
       1194, 10 L. Ed. 2d 215 (1963), whether prejudice occurred from the
       suppressed evidence collectively, not simply on an item-by-item basis;
       that is, it must assess its cumulative effect on the fact finder in the light
       of other evidence.
14.	   Pretrial Procedure: Prosecuting Attorneys: Evidence: Words and
       Phrases. Whether a prosecutor’s failure to disclose evidence results in
       prejudice depends on whether the information sought is material to the
       preparation of the defense, meaning that there is a strong indication that
       such information will play an important role in uncovering admissible
       evidence, aiding preparation of witnesses, corroborating testimony, or
       assisting impeachment or rebuttal.
15.	   Trial: Evidence: Convictions: Presumptions. Brady v. Maryland, 373
       U.S. 83, 83 S. Ct. 1194, 10 L. Ed. 2d 215 (1963), does not apply after
       a defendant has been convicted in a fair trial and the presumption of
       innocence no longer applies.
16.	   Prosecuting Attorneys: Evidence. A prosecutor has a duty to learn of
       favorable material evidence known to others acting on the government’s
       behalf in a case.

                    I. NATURE OF CASE
   This is Jack E. Harris’ appeal from the district court’s order
dated March 10, 2016, denying him postconviction relief fol-
lowing an evidentiary hearing held on June 28, 2013. The
court failed to apply the correct standard to Harris’ claim that
the State suppressed evidence favorable to him at his 1999
murder trial. The court also failed to address Harris’ claims
concerning the State’s plea agreement with Harris’ accom-
plice. Accordingly, we affirm in part and in part reverse, and
remand the cause for the court to resolve Harris’ outstanding
claims in a manner consistent with the standards set out in
this opinion.
                     II. BACKGROUND
               1. Facts of Crime From H arris’
                         Direct A ppeal
   In 1999, Harris was convicted of first degree murder and
use of a deadly weapon to commit a felony for the 1995 death
of Anthony Jones, an Omaha drug dealer. Jones was found
dead in his apartment; he had been shot in the head. Harris’
alleged accomplice was Howard “Homicide” Hicks, whom
Harris had met that summer through Corey Bass, a mutual
acquaintance.

                               Cite as 296 Neb. 317

   In December 1996, Bass was murdered. Officers who were
investigating Bass’ murder spoke to his brother, who had
been incarcerated that year with Harris and a third inmate.
Bass’ brother told the officers that while Harris and he were
incarcerated, Harris admitted that he and someone named
“Homicide” had murdered Jones. The third inmate reported
that Harris had told him Jones was killed because Jones recog-
nized Harris while Harris was robbing him.
   In May 1997, officers arrested Hicks for Jones’ murder.
After his arrest, Hicks confessed to law enforcement that he
and Harris had robbed Jones but that Harris had killed Jones.
   The State first tried Harris for Jones’ murder in March
1999. The court declared a mistrial because the jury dead-
locked. When the State retried Harris in July 1999, the jury
found him guilty of first degree murder and use of a deadly
weapon to commit a felony. Hicks, Bass’ brother, and the
third inmate, as well as another man, Robert Paylor, testified
against Harris; Paylor also claimed that Harris had told him
about Harris’ involvement with Jones’ murder. Leland Cass,
an Omaha police officer, also testified at trial. He testified that
while investigating Bass’ murder, he interviewed Harris, and
that during the interview, Harris had identified Hicks by the
nickname “Homicide.”1
   On direct appeal, we rejected Harris’ claim that the State
failed to disclose Cass’ report about the interview with Harris.
We held that the court did not abuse its discretion in conclud-
ing that Harris had failed to show that the prosecution did not
provide him with Cass’ report.

         2. Interlocutory A ppeal of First A mended
              Motion for Postconviction R elief
  In 2004, we decided Harris’ first postconviction appeal.2
Harris contended that he was entitled to an evidentiary hearing

on claims regarding the alleged nondisclosure of Cass’ police
report. As stated above, Cass testified at trial that during a
1996 police interview, Harris identified Hicks by the nickname
“Homicide.” Part of Harris’ defense was that he did not know
Hicks and that Hicks had lied when he said that he and Harris
had robbed Jones together. The Cass report provided direct
statements from Harris that he knew Hicks. We concluded
that Harris was entitled to an evidentiary hearing on his claim
that the prosecution had failed to disclose the Cass report and
whether he was prejudiced by that misconduct if it occurred.
Similarly, we held he was entitled to an evidentiary hearing
on his claims of ineffective assistance of counsel related to the
police report and remanded the matter for further proceedings.
We rejected his remaining claims.
            3. A ppeal of Judgment on First A mended
                Motion for Postconviction R elief
   On remand, Harris was granted leave to file a second
amended motion for postconviction relief. In 2007, we con-
sidered Harris’ appeal of the judgment on his first amended
motion for postconviction relief.3 Harris again claimed that
he was prejudiced by Cass’ statement that he knew Hicks
by the nickname “Homicide,” because this testimony forced
Harris’ trial counsel to abandon his defense that Harris did not
know Hicks.
   We stated that it was “now undisputed that although the
State agreed to provide Harris with a copy of all police reports,
the State failed to provide Harris with a copy of the Cass
report prior to trial.”4 But we noted that Harris’ trial counsel
did not move to continue the trial because of the late discovery
of the Cass report, and Harris did not claim that the late dis-
closure impeded his attorney’s ability to prepare a defense. We
further stated that because Harris was present at the interview,

he knew the report’s contents. We concluded that he was not
prejudiced by Cass’ statement in the light of testimony from
three other witnesses who stated that Harris had admitted to
the crime.

               4. First A ppeal of Second Motion
                    for Postconviction R elief
   In 2008, Harris filed a second motion for postconviction
relief, a motion for a new trial, and a motion for a writ of
error coram nobis.5 All three motions primarily rested on his
claim that he had discovered new evidence that Hicks testified
falsely at Harris’ trial and that Hicks had acted alone in the
murder. Harris submitted the affidavits of Terrell McClinton
and Curtis Allgood in support of the motions. McClinton
stated that Hicks had confessed to him that he killed Jones.
Allgood “provided details placing Hicks near the crime scene
at the time of the murder and corroborated some of the
information provided by McClinton.”6 Harris alleged that he
was unaware of this information until McClinton contacted
Harris’ attorney in 2006 and that he was prevented from dis-
covering it because of misconduct by the prosecutor and the
State’s witness.
   The district court agreed to grant Harris an evidentiary
hearing, but stated that because it had done so, it would not
address his motions for a new trial and a writ of error coram
nobis. Before the evidentiary hearing, however, the district
court bench for Douglas County recused itself when the pros-
ecutor at Harris’ trial was appointed to the bench. In August
2009, a Sarpy County judge was appointed to hear Harris’
postconviction motion. In December 2010, the court permitted
Harris to file a third amended motion, which added allegations
of newly discovered evidence that the prosecutor mispresented

or allowed Hicks to misrepresent the nature of Hicks’ plea
agreement during Harris’ trial.7
   At the start of the evidentiary hearing in June 2013, the
court announced that the “matter comes on for a full hearing
on [Harris’] Third Amended Motion for Postconviction Relief.”
However, the record does not reflect that Harris filed the third
amended motion for postconviction relief.
   After the hearing, the district judge dismissed Harris’ post-
conviction motion without addressing the merits on the basis
that Harris had the two other pending motions for relief, i.e.,
his motions for a new trial and a writ of error coram nobis.
The court concluded that those motions did not show that
postconviction relief was the sole remedy available to Harris
as required under Nebraska’s postconviction statutes.8 Harris
subsequently appealed that ruling.
   In December 2015, we held that when a district court is
presented with simultaneous motions for postconviction relief
and some other type of relief, the court must dismiss the post-
conviction motion without prejudice when the allegations, if
true, would warrant relief through the alternative remedy that
the defendant sought. But if the court determines that no other
remedy is available and the postconviction motion is not pro-
cedurally barred under § 29-3003, the court must consider the
motion on the merits.
   We concluded that Harris’ motion for a new trial was not an
available remedy because the motion was time barred. We also
concluded that a writ of error coram nobis was not an avail-
able remedy for Harris’ claim that a witness testified falsely.
Because Harris could not obtain relief through the alternative
remedies he sought, we held that the court erred in dismissing
his motion for postconviction relief. We reversed the court’s
judgment and remanded the cause for the court to consider the
merits of Harris’ postconviction motion. The district court’s

ruling on the merits presents the issues now currently before
this court.

                   5. Proceedings on R emand
   On remand from Harris’ first appeal of his latest motion for
postconviction relief, the district court did not conduct a new
evidentiary hearing. Instead, the court considered the evidence
presented at the 2013 evidentiary hearing.
   At the 2013 hearing, at Harris’ request and with the State’s
consent, the court took judicial notice of the bill of exceptions
for Harris’ second trial in 1999. Nonetheless, in this appeal, the
parties cite exhibit numbers referencing the bill of exceptions
from Hicks’ 1999 trial and quote excerpts from the trial, all
of which are not part of the record before us. The only record
before us is the evidence offered at the 2013 evidentiary hear-
ing. Most of the facts that we set out below either are in the
record from the 2013 postconviction hearing or come from our
previous records and decisions in this case, which we judi-
cially notice.9
   As mentioned above, in Harris’ third amended motion, he
added the allegation that “the prosecutor engaged in miscon-
duct by misrepresenting or allowing Hicks to misrepresent
the nature of the plea agreement at Harris’ trial.”10 Relatedly,
Harris alleged that the prosecutor failed to disclose impeach-
ment evidence regarding the State’s true plea agreement with
Hicks. Harris contended that contrary to the prosecutor’s rep-
resentations, the true plea agreement included the following
terms: (1) The prosecutor would meet with Hicks’ attorney and
the judge and make recommendations for lenient sentencing;
(2) neither the prosecutor nor Hicks’ attorney would object
to Harris’ waiver of a presentence investigation report, which
would have alerted the judge that Paylor had identified Hicks
as his shooter; (3) the prosecutor would make a statement

regarding Hicks’ sincere remorse for his involvement in the
case of Jones’ homicide; (4) the prosecutor would not object
to Hicks’ attorney’s recommendations for sentencing nor object
to certain illegal credit for time served on different charges;
and (5) the prosecutor would advise the court that she had spo-
ken to Jones’ family members and that they did not object to
her recommendations.
   However, in the court’s 2016 order denying relief, the court
did not address Harris’ claims regarding Hicks’ plea agreement.
Instead, the court’s order stated that Harris had filed a “sec-
ond” motion for postconviction relief and addressed the claims
raised in only that second motion.
   The court specifically ruled upon Harris’ claims that the State
suppressed information in the possession of Allgood before
Harris’ trial and information in the possession of McClinton
before Harris’ trial, direct appeal, or postconviction proceed-
ings. To address Harris’ claims and the court’s rulings, we must
provide more factual context.

                      6. A dditional Facts
   In 2006, McClinton wrote Harris’ postconviction attorney
with information that he had obtained in prison about homi-
cides in Omaha, including Jones’ homicide. McClinton wrote
that Hicks had told him about killing Jones and walking to
Allgood’s house afterward. McClinton refused to be trans-
ported to court for the 2013 evidentiary hearing, but the court
received his 2007 affidavit into evidence.
   In his affidavit, McClinton stated that for an unspecified
period, he had worked for Bass, who was a major drug dealer
in Douglas County. McClinton would “administer beatings” to
people who owed Bass money or drugs. McClinton said that
Hicks killed people for Bass and was referred to as “Homicide”
because “he will leave you dead.” McClinton said that in 2001,
he met with Hicks in Omaha and Hicks talked about some of
Hicks’ crimes.

                        Cite as 296 Neb. 317

   McClinton’s affidavit further stated that Hicks told
McClinton that despite his testimony at Harris’ trial, Hicks had
shot Jones. Hicks said that he had waited outside Jones’ apart-
ment door until Jones came home and then took Jones inside
to rob him. Hicks said he shot Jones twice because his gun
misfired. But Hicks could not find Jones’ drugs and needed
to walk to a telephone booth to call Bass and ask where Jones
kept them. Hicks put a vase in the doorway so he could get
back inside. After Bass told Hicks where to look, he returned
to Jones’ apartment and found the drugs. Then he walked to
Allgood’s house, but Allgood kicked him out because he got
mud on the floor.
   Finally, McClinton’s affidavit stated that he “tried” to call
the gang unit with this information in 2004, contacted a fed-
eral agent in 2005, and wrote the county attorney about it in
June 2006.
   McClinton’s information led Harris’ postconviction attorney
to Allgood, who signed an affidavit in 2007. In that affidavit,
Allgood stated that in 1995, he lived within blocks of Jones’
apartment. He said that he installed hydraulic suspensions on
cars, that some of his customers were people involved in gangs
and illegal drugs, and that it was not unusual for these cus-
tomers to “‘hang out’” at his house. Allgood said that Bass, a
“known street gangster” and major drug dealer, and Hicks were
among the customers who would spend time at his house. He
also knew Harris. He said that he would sometimes see Bass
with Harris but would not see Hicks with Harris. Allgood said
the following regarding August 22, 1995: It was a rainy day;
Bass and another person were at Allgood’s house, and Harris
was not there. Around 10:30 p.m., Hicks ran into Allgood’s
kitchen without knocking and appeared very agitated. He was
wearing dark clothes and had gloves in his back pocket.
Allgood was upset because Hicks was tracking mud onto the
floor. He overheard Hicks tell Bass that “‘it was handled.’”
Hicks and Bass talked inside for about 15 minutes; then they
went outside and left about 10 minutes later.

   At the 2013 hearing, Allgood testified that the night of
Jones’ murder had stood out to him because he learned about
the murder shortly afterward. He said that Hicks had burst into
his kitchen like “he was just coming in to start a fight or some-
thing.” Allgood told Hicks to take his muddy boots outside, but
Hicks insisted on talking to Bass. Hicks was erratic in speaking
to Bass while they were in the kitchen, but when Allgood heard
Hicks say that “[i]t was handled,” Bass seemed happy.
   Allgood further testified that later, in 1996 or 1997, a plain-
clothes police officer, accompanied by another man, came
to ask him questions about Jones’ homicide. Allgood did not
know Jones but knew of him. He believed that Jones was also
involved in illegal drug activities with Bass. Allgood could
not remember the officer’s name but said that he identified
himself as a police officer and took notes. The officer gave
Allgood a “brief synopsis” of the homicide investigation and
asked Allgood if he had ever seen Harris, Hicks, and Bass “all
together around that time at [Allgood’s] house.” Allgood told
the officer that he did not see them all together. But he specifi-
cally testified that he told the officer he “saw [Bass] and Hicks
together that night.”
   However, on cross-examination, the prosecutor asked
Allgood the following questions, and Allgood gave the follow-
ing answers:
         Q. The information in your affidavit pertaining to when
      . . . Hicks came into your house that night in August of
      1995 —
         A. Yes, sir.
         Q. — did you tell the police officer about that?
         A. No. Because he didn’t ask me that question.
         Q. Did you tell anybody in law enforcement about
      that until you revealed it when [postconviction counsel’s]
      investigator came and talked to you?
         A. No. I didn’t.
         Q. Your wife? Anybody?
         A. No.

                        Cite as 296 Neb. 317

   Allgood said that he did not tell the police investigator about
the information in his affidavit because he had not put the facts
all together and it would have hurt his business to talk about
some things to police officers.
   At the 2013 hearing, Harris offered evidence to show that his
trial attorney did not receive any police reports about Allgood
and that the prosecutor likely knew about him. Specifically,
Harris presented evidence that on December 16, 1996, Officer
W. Agnew wrote a “supplementary” police report for the inves-
tigation into the murder of Bass. In the report, Agnew stated
that he had been asked to find out if Harris knew anything
about Bass’ death. A box was drawn around text in which
Agnew reported that in November 1996, Harris had traded
in a “GMC Blazer [for a] Mercedes Benz.” The information
was relevant because Hicks had testified that Harris owned
a Blazer.
   After the first day of Harris’ second trial, the prosecutor
faxed six pages to Harris’ attorney: a cover sheet, an unfiled
notice to seek endorsement of Agnew and Allgood as wit-
nesses, and all four pages of Agnew’s supplemental report. But
the original fax information at the top of Agnew’s supplemen-
tal report showed that his report was part of 29 pages that were
faxed to the prosecutor on the morning of July 19, 1999. The
prosecutor filed the notice to endorse Agnew and Allgood on
July 20.
   Harris’ attorney could not recall receiving Agnew’s report
or speaking to the prosecutor about it. Agnew’s report did
not mention Allgood’s name. But Harris’ attorney believed
that because of the prosecutor’s notice to endorse Agnew and
Allgood, he would have spoken to the prosecutor about these
witnesses. However, he said that if the prosecutor had indicated
that she would not call Allgood, he would not have worried
about him. He stated that if he had known about the state-
ments in Allgood’s 2007 affidavit, he would have investigated
to determine whether Hicks “was with others or alone in terms
of the story that he related in the first and second trials.” He

stated that this information would have undermined Hicks’
credibility and reinforced Harris’ alibi.
   Harris testified that during his second trial, the prosecutor
sat at the same table with the defense. He stated that he could
see the prosecutor’s notice to endorse Agnew as a witness and
that Agnew worked in the police department’s gang unit. Harris
asked the prosecutor what Agnew would say, because Harris
was not a gang member. The prosecutor asked Harris whether
he had owned a “little Blazer,” because Hicks had said he did.
Harris told the prosecutor that he had owned a “big Blazer,”
and the prosecutor said she would not call anyone about the
Blazer. When Harris asked what Allgood would say, the pros-
ecutor responded that she was not going to use him. When
Harris asked his attorney what Allgood would say, his attorney
said he did not have any paperwork on Allgood.
   In her 2011 deposition, the prosecutor testified that she could
not recall why she had endorsed Agnew or Allgood. She said
that in general, she would endorse a witness to “be on the safe
side,” if she had gotten some information from a police report
that caused her to think “maybe there might be something.”
She also acknowledged the existence of a “gang intelligence
unit” in the police department when she was a prosecutor. She
said that as a prosecutor, she did not want to know about any
of the unit’s collected information “that [she could not] tell the
defense attorney,” and that the unit’s policy was not to tell her
anything “unless it can be disclosed. . . . If they think it’s too
sensitive, then [they] don’t tell [her].”

                        7. Court’s Order
   In its 2016 ruling on Harris’ motion for postconviction
relief, the district court determined that Harris was not enti-
tled to relief on his claims that (1) the prosecutor failed
to disclose McClinton’s statements to Harris’ trial counsel,
appellate counsel, or postconviction counsel and (2) if Harris’
trial counsel knew about McClinton’s information, counsel
provided ineffective assistance in failing to call McClinton as

a witness. The court found that there was no evidence that the
prosecutor or the defense attorney knew about McClinton’s
existence: “Given that lack of knowledge, it would be impos-
sible for either of them to know, suspect, look into or learn
about the potentially exculpatory evidence [McClinton]
recites in his letter to [Harris’ postconviction counsel] or in
his affidavit.”
   The court also concluded that Harris was not entitled to relief
on his claims that (1) the State failed to disclose Allgood’s
statements to Harris and (2) if Harris’ trial attorney knew about
Allgood’s statements, counsel provided ineffective assistance
in failing to call Allgood as a witness:
          The record does contain some evidence to indicate
      that the prosecutor knew about . . . Allgood’s physical
      existence and the possibility that he possessed at least
      some information that was of potential utility in [Harris’]
      original trial. However, there is no information contained
      within the record and evidence currently before this
      Court to indicate that at any time prior to and/or during
      [Harris’] trial did either the State . . . or defense counsel
      . . . know about any potential exculpatory information in
      . . . Allgood’s possession. More specifically, there is no
      evidence before this Court for it to make a determina-
      tion that [the prosecutor] or [defense attorney] possessed
      even the slightest bit of information about the potentially
      exculpatory information contained within . . . Allgood’s
      affidavit . . . until it was brought to their attention as
      a result of the filing of this postconviction motion in
      January of 2008. Further, . . . Allgood’s testimony at the
      hearing held on June 28, 2013, corroborates the fact that
      he did not share, hint at, or in any other manner reveal
      the potentially exculpatory information contained in [his
      affidavit] with anyone, including representatives of the
      State, the defense or any members of law enforcement.
      . . . Accordingly, the Court finds that this contention is
      without merit.

  As stated, the court did not address Harris’ claims regarding
Hicks’ plea agreement.
                III. ASSIGNMENTS OF ERROR
   Harris assigns that the court erred in overruling his third
amended motion for postconviction relief for the following
reasons: (1) Harris’ convictions were procured through pros-
ecutorial misconduct, which violated his right to due process;
(2) the court failed to address Harris’ claim that the prosecutor
improperly misrepresented the nature of Hicks’ plea agreement;
and (3) Harris’ trial counsel provided ineffective assistance.
                 IV. STANDARD OF REVIEW
   [1-3] In reviewing a trial court’s factual findings following
an evidentiary hearing in a postconviction case, an appellate
court will uphold those findings unless they are clearly errone-
ous.11 We independently review questions of law decided by a
lower court.12 The determination of constitutional requirements
presents a question of law.13
   [4] Likewise, when a claim of ineffective assistance of
counsel presents a mixed question of law and fact, we review
the lower court’s factual findings for clear error but indepen-
dently determine whether those facts show counsel’s perform­
ance was deficient and prejudiced the defendant.14
                        V. ANALYSIS
  Before addressing the parties’ specific arguments regarding
Harris’ suppression of evidence claims, we set out the stan-
dards that guide our review of those claims.

         1. Prosecution’s Duty to Disclose Favorable
            Evidence and Standard of M ateriality
                to Show Due P rocess Violation
   [5-7] In Brady v. Maryland,15 the U.S. Supreme Court held
that the prosecution has a duty to disclose all favorable evi-
dence to a criminal defendant prior to trial. Favorable evidence
includes both exculpatory and impeachment evidence.16 The
“suppression by the prosecution of evidence favorable to an
accused upon request violates due process where the evidence
is material either to guilt or to punishment, irrespective of the
good faith or bad faith of the prosecution.”17
   [8,9] Since deciding Brady, the U.S. Supreme Court has
clarified that the Due Process Clause requires the prosecu-
tion to disclose favorable material evidence even if a defense
counsel did not request it.18 Moreover, a prosecutor has a duty
to learn of favorable material evidence known to others act-
ing on the government’s behalf in a case.19 Thus, the State’s
duty to disclose favorable material evidence exists even if the
evidence was “‘known only to police investigators and not to
the prosecutor.’”20

   [10] But the prosecution’s undisclosed evidence must be
material either to guilt or to punishment, and the prosecu-
tion’s suppression of favorable evidence violates a defendant’s
due process right to a fair trial only if the suppressed evi-
dence is sufficiently significant to undermine confidence in
the verdict.21
   [11] In United States v. Bagley,22 the Supreme Court held that
the same standard of materiality applies to undisclosed favor-
able evidence whether a defense attorney made no request, a
general request, or a specific request for it.23 The Court adopted
the standard of materiality that it had relied on in Strickland
v. Washington24 for all claims of prosecutorial suppression of
favorable material evidence: “The evidence is material only if
there is a reasonable probability that, had the evidence been
disclosed to the defense, the result of the proceeding would
have been different.”25
   [12] Under Kyles v. Whitley,26 the touchstone of a “‘reason-
able probability’” of a different result is not a sufficiency of
the evidence test and does not require a defendant to show that
an acquittal was more likely than not with the suppressed evi-
dence. Instead, the question is whether the defendant received
a fair trial without the evidence:
      A “reasonable probability” of a different result is accord-
      ingly shown when the government’s evidentiary sup-
      pression “undermines confidence in the outcome of the
      trial.”. . .

          . . . One does not show a Brady violation by dem-
       onstrating that some of the inculpatory evidence should
       have been excluded, but by showing that the favorable
       evidence could reasonably be taken to put the whole case
       in such a different light as to undermine confidence in
       the verdict.27
Thus, if the Bagley standard of materiality is satisfied—i.e.,
the defendant shows that the prosecution’s failure to disclose
favorable evidence prejudiced the defendant by undermin-
ing confidence in the outcome of the trial28—the suppression
­cannot be found harmless.29
    As we have recognized,30 in Strickler v. Greene,31 the
 Supreme Court set out the three primary components of
 a Brady violation. First, the “evidence at issue must be
 favorable to the accused, either because it is exculpa-
 tory, or because it is impeaching.”32 Second, the “evidence
 must have been suppressed by the State, either willfully or
 inadvertently.”33 Third, prejudice from the suppression “must
 have ensued.”34
    [13] But when the State has suppressed more than one
 item of favorable material evidence, a court must also con-
 sider whether prejudice occurred from the suppressed evidence

collectively, not simply on an item-by-item basis; that is, it
must assess its cumulative effect on the fact finder in the light
of other evidence.35
   [14] Under Neb. Rev. Stat. § 29-1912 (Reissue 2008),
Nebraska’s primary discovery statute in criminal cases, whether
a prosecutor’s failure to disclose evidence results in prejudice
depends on whether the information sought is material to the
preparation of the defense, meaning that there is a strong
indication that such information will play an important role
in uncovering admissible evidence, aiding preparation of wit-
nesses, corroborating testimony, or assisting impeachment or
rebuttal.36 Accordingly, we have analyzed whether a pros-
ecutor failed to disclose material evidence under § 29-1912
in an appeal from a postconviction proceeding,37 which is a
remedy available only for violations of a defendant’s constitu-
tional rights.38
   Having set out the relevant standards for evaluating a
defend­ant’s suppression claims, we turn to the parties’ argu-
ments regarding Harris’ specific claims.

                    Convicted and Sentenced
   According to McClinton’s affidavit, 2004 was the first year
that he “tried” to contact any law enforcement officers with
information about Hicks’ confessing to killing Jones. Harris
was convicted and sentenced in 1999. We decided his direct
appeal in 2002 and his first postconviction appeal in 2004.
Harris does not dispute the court’s finding that the prosecutor
did not know McClinton even existed during Harris’ trial or
sentencing. But Harris argues that this court should interpret
Nebraska’s Constitution and postconviction statutes to require
an ongoing duty for the State to disclose exculpatory informa-
tion that it learns about after a defendant is convicted and sen-
tenced. It relies on the U.S. Supreme Court’s 2009 decision in
District Attorney’s Office for Third Judicial Dist. v. Osborne.39
But Osborne does not support Harris’ argument.
   Long before Osborne, in a 1976 civil rights case, the
Supreme Court stated that at a trial, a prosecutor’s duty to dis-
close favorable evidence is enforced by due process require-
ments, but that after a trial has concluded, the prosecutor is
bound by his or her ethical duties.40 Later, in a 1986 habeas
case, the Court declined to decide whether Brady requires a
prosecutor to disclose favorable evidence that the prosecu-
tor does not learn about until after a defendant is convicted
and sentenced.41 Since then, various federal courts have held
that when state investigators or prosecuting officers know of

favorable evidence before or during a defendant’s trial, the
State’s duty to disclose the evidence continues to posttrial
proceedings that are determinative of guilt or innocence.42
But in the absence of clear guidance, lower federal courts had
been split on whether Brady requirements extend to favorable
evidence that the prosecution does not learn about until after
a trial is completed.43 In Osborne, the U.S. Supreme Court
effectively resolved that split.
   In Osborne, a state prisoner sued Alaska state officials in a
civil rights action for violating his due process right to obtain
biological evidence that was used to convict him of kidnapping
and assault offenses. He wanted the evidence to perform DNA
testing that was unavailable at the time of his trial. The Ninth
Circuit extended a previous holding that the Brady disclosure
requirements continue to posttrial proceedings based upon a
fundamental fairness requirement that the State must come
forward with any exculpatory evidence in its possession when
a habeas petitioner needs it to make a colorable showing of
actual innocence.44 The circuit court noted that the prisoner had
a “potentially viable” state constitutional claim of “actual inno-
cence,” and it relied on the “well-established assumption” that
a similar claim arose under the federal Constitution and con-
cluded that as a result, these potential claims extended some
of the State’s Brady obligations of disclosure of favorable
evidence to the postconviction context.45 However, the circuit
court declined to set out a standard of materiality because it

concluded the facts of the case were strong enough to warrant
disclosure regardless of the standard.
   [15] The U.S. Supreme Court reversed. It agreed that
Alaska’s statute for newly discovered evidence had created a
liberty interest for convicted individuals to prove their inno-
cence and that a state-created right can sometimes “‘beget yet
other rights to procedures essential to the realization of the par-
ent right.’”46 But it concluded that the Ninth Circuit “went too
far . . . in concluding that the Due Process Clause requires that
certain familiar preconviction trial rights be extended to protect
[the respondent’s] postconviction liberty interest.”47 The Court
specifically held that Brady does not apply after a defendant
has been convicted in a fair trial and the presumption of inno-
cence no longer applies:
           A criminal defendant proved guilty after a fair trial
       does not have the same liberty interests as a free man.
       At trial, the defendant is presumed innocent and may
       demand that the government prove its case beyond rea-
       sonable doubt. But “[o]nce a defendant has been afforded
       a fair trial and convicted of the offense for which he
       was charged, the presumption of innocence disappears.”
       . . . “Given a valid conviction, the criminal defendant has
       been constitutionally deprived of his liberty.” . . .
           The State accordingly has more flexibility in deciding
       what procedures are needed in the context of postconvic-
       tion relief. “[W]hen a State chooses to offer help to those
       seeking relief from convictions,” due process does not
       “dictat[e] the exact form such assistance must assume.”
       . . . [The respondent’s] right to due process is not parallel
       to a trial right, but rather must be analyzed in light of the
       fact that he has already been found guilty at a fair trial,
       and has only a limited interest in postconviction relief.
       Brady is the wrong framework.

         Instead, the question is whether consideration of [the
      respondent’s] claim within the framework of the State’s
      procedures for postconviction relief “offends some prin-
      ciple of justice so rooted in the traditions and conscience
      of our people as to be ranked as fundamental,” or “trans-
      gresses any recognized principle of fundamental fairness
      in operation.”48
The Court concluded that Alaska’s procedures were sufficient
to vindicate its state-created right to show actual innocence
without the need to extend the Brady disclosure requirements
to postconviction actions.
   Harris contends that Nebraska’s “postconviction proce-
dures and new trial provisions are fundamentally inadequate
to vindicate the substantive rights provided.”49 At the time
of his conviction and sentencing, pursuant to Neb. Rev. Stat.
§ 29-2103(4) (Reissue 1995), a motion for a new trial resting
on newly discovered evidence had to be filed within 3 years of
the defendant’s conviction.50
   Since Harris’ conviction, the Legislature has amended
Nebraska’s statutes dealing with motions for a new trial.51
Effective August 30, 2015, a motion for new trial resting
on newly discovered evidence must be brought within 5
years of the verdict, “unless the motion and supporting docu-
ments show the new evidence could not with reasonable
diligence have been discovered and produced at trial and such
evidence is so substantial that a different result may have
occurred.”52
   But even before the Legislature amended Nebraska’s stat-
utes dealing with a motion for a new trial, this court had
held open the possibility of postconviction relief for a strong

showing of actual innocence. We have explained that a pris-
oner’s claim that the State was incarcerating an innocent per-
son who could no longer present newly discovered evidence
would raise a potential due process violation.53 Osborne did
not establish a new substantive right; the Court was merely
evaluating whether a state’s procedures, specifically Alaska’s,
were sufficient to “vindicate its state right to postconvic-
tion relief.”54
   Harris does not claim that McClinton’s affidavit was suf-
ficiently compelling to show his actual innocence in a post-
conviction proceeding.55 Nor does Harris claim that Nebraska’s
procedures are inadequate to protect his statutory postconvic-
tion rights. Instead, he claims that Nebraska’s statutory rights
are inadequate to support a purported right to have the State
disclose any exculpatory information that it receives long after
a case is closed.
   After a case is closed, there may be ethical duties that
require prosecutors to take action upon learning of evidence
that creates a reasonable likelihood the defendant did not
commit the crime.56 But Nebraska’s postconviction statutes
provide relief only for constitutional violations that render a
conviction void or voidable.57
   Harris cites no authority to support his argument that the
3-year time limitation for claims of newly discovered evi-
dence violated a recognized principle of fundamental fair-
ness. And his claim that he has a substantive right to have
the State disclose exculpatory evidence that it learns about
after a final judgment directly conflicts with the U.S. Supreme
Court’s holding in Osborne that Brady does not apply to

postconviction proceedings.58 We conclude that the court did
not err in denying Harris relief on his claim that the State
failed to disclose information McClinton allegedly reported to
law enforcement officers in 2004 or later.
              3. Court A pplied Wrong Standards
                 in Determining That State Did
                 Not Violate Duty to Disclose
                  Information A bout A llgood
   The district court concluded that Harris was not enti-
tled to relief on his claims that the State failed to disclose
Allgood’s statements to a police officer in 1996 or 1997.
The court reasoned that the evidence failed to show that
the prosecutor “possessed even the slightest bit of informa-
tion about the potentially exculpatory information contained
within . . . Allgood’s affidavit.” Additionally, the court found
that Allgood’s testimony showed that he did not reveal any
potentially exculpatory information with anyone, “including
representatives of the State, the defense or any members of
law enforcement.”
              (a) Parties’ Contentions Regarding
                     Allgood’s Statements
   Harris argues that the evidence shows that the prosecutor’s
practice was to allow law enforcement officers to dictate what
information the prosecution would see on a case. Despite this
practice, Harris contends that the prosecutor would not have
endorsed Allgood as a witness without knowing something
about his potential testimony and that the evidence strongly
suggests the prosecutor received this information in the miss-
ing pages the police department faxed to the prosecutor on July
19, 1999.
   Harris also contends that Allgood’s statements to the offi-
cer who interviewed him about Jones’ homicide constituted

potentially exculpatory evidence and impeachment evidence.
He argues that if his trial counsel had known about Allgood’s
statements to the officer, he would have contacted him and
learned about the rest of the story that was set out in Allgood’s
affidavit. Harris further contends that Allgood’s statements to
the officer would have corroborated Harris’ alibi defense and
permitted him to impeach Hicks’ credibility. He argues that
Allgood’s statements to the officer contradicted Hicks’ testi-
mony that he and Harris drove around town together after rob-
bing Jones.
   The State contends that Allgood’s statements to the officer—
i.e., that he did not see Hicks, Harris, and Bass together the
night of the murder, but did see Hicks and Bass together—did
not constitute evidence favorable to Harris because they were
neither exculpatory nor impeaching. It argues that even if
Harris’ trial counsel had investigated and learned that Hicks
was at Allgood’s house the night of the murder, that evidence
shows at most that Harris was not there when Hicks was or that
Hicks was also involved in the murder of Jones. But it would
not show that Harris was not involved.

                          (b) Resolution
   [16] The court’s reasoning that no suppression occurred
because the prosecutor did not know about Allgood’s state-
ments to investigators was incorrect. Under both federal and
state law, the prosecutor had a duty to learn of favorable
material evidence known to others acting on the government’s
behalf in the case. Thus, the State’s duty to disclose favorable
material evidence existed even if the evidence was known only
to police investigators and not to the prosecutor.
   Further, the court’s summary conclusion that Allgood’s state-
ments were not exculpatory did not comply with the applicable
standards for evaluating Harris’ claims. Favorable evidence
includes both exculpatory and impeachment evidence.
   Harris alleged in his motion that Allgood’s statements would
have corroborated his alibi defense and contradicted Hicks’

testimony that he left the murder scene with Harris and drove
around with him, disposing of evidence and distributing the
money. Harris also alleged that he would have cross-examined
Hicks about his contacts with Bass. His trial attorney stated
that knowing whether Hicks “was with others or alone in terms
of the story that he related” may have undermined Hicks’ cred-
ibility and reinforced Harris’ alibi.
   The court did not consider whether Allgood’s statements to
the officer would have impeached Hicks’ credibility. Nor did
the court explain why it concluded that Allgood’s statements
were not “potentially exculpatory information.”
   As explained, we do not have the bill of exceptions from
Harris’ trial. Whether the State suppressed material exculpatory
information by not disclosing Allgood’s statements must be
evaluated in the light of the trial evidence.59 The court’s sum-
mary conclusion does not satisfy that requirement. Accordingly,
we remand the cause for further clarification as to whether
Allgood’s statements were not exculpatory or would not have
impeached Hicks’ credibility.
              4. R ecord Is Unclear as to Which
               Motion for Postconviction R elief
                       Court Considered
   As previously explained, on January 17, 2008, Harris filed
a “Second Verified Motion for Postconviction Relief.” In that
motion, Harris raised the issue of prosecutorial misconduct for
failing to disclose potentially exculpatory information within
the possession of Allgood and McClinton.
   On November 13, 2010, Harris filed a “Motion for Leave
to File Third Amended Motion for Postconviction Relief.”
In that motion, Harris alleged that the motion was identi-
cal to his second motion except that it raised two claims
involving Hicks’ plea agreement: (1) The prosecutor failed
to disclose the true plea agreement, and (2) the prosecutor

misrepresented or allowed Hicks to misrepresent the nature
of his plea agreement. On December 16, the district court
granted the motion for leave and allowed Harris to file a third
amended motion for postconviction relief. As mentioned pre-
viously, the record reflects that Harris failed to file his third
amended postconviction motion after the court gave him leave
to do so.
   At the commencement of the evidentiary hearing in 2013,
the district court announced that the matter was before the
court on the third amended motion for postconviction relief.
When the court announced that it was hearing Harris’ third
amended motion, the State did not assert that Harris had failed
to file the motion. Instead, the State offered a copy of Harris’
third amended motion and the court’s docket entries, which
showed that the court had given Harris leave to file it.
   After clarifying the record, the prosecutor stated that the
State had not found a record of Harris’ most recent motion.
But the State did not contend that Harris’ claims regarding
Hicks’ plea agreement were beyond the scope of the pleadings.
Instead, it argued that the court should dismiss Harris’ postcon-
viction motion under § 29-3003 because the record failed to
show that the court had ever dismissed his motions for a new
trial and a writ of error coram nobis.
   The record further reflects that Harris presented certain
evidence that was relevant only to his claims about Hicks’
plea agreement. He questioned his trial attorney about Hicks’
shooting of Paylor and Hicks’ plea agreement in regard to
Jones. He submitted exhibits that showed the State’s original
information charging Hicks with assault, its amended informa-
tion charging Hicks’ with robbery, Hicks’ 2011 deposition,
Hicks’ sentencing hearing, and the court’s order sentencing
Hicks. The State’s only objection to this evidence was that
the claim was procedurally barred—not that it was beyond the
scope of the pleadings. The court allowed the State to have a
continuing objection regarding its procedural bar argument,
but overruled the objection. At no point did the State argue

           Nebraska Supreme Court A dvance Sheets

                        Cite as 296 Neb. 317

that Harris’ evidence was irrelevant to the pleading properly
before the court.
   However, when the district court issued its order on the
merits, the court referenced only that the matter came on for
a full hearing on Harris’ “Motion for Postconviction Relief.”
Further, the order addressed Harris’ claims for prosecutorial
misconduct only for failing to disclose potentially exculpatory
information within the possession of Allgood and McClinton.
The order was silent as to Harris’ claims regarding Hicks’
plea agreement.
   As a result, we cannot determine from the record whether
the district court intentionally or erroneously failed to rule
on Harris’ claims regarding Hicks’ plea agreement. Though
an argument can be made that the parties consented to try all
of the claims set forth in Harris’ third amended motion for
postconviction relief, making such determination would be
needlessly speculative. The better course is for this matter to
be remanded to the district court for clarification as to which
motion the court intended to rule on and, if necessary, the
entry of an order which dispenses with all of Harris’ claims
for relief.

              5. H arris’ New Claim of Ineffective
               Assistance Is Procedurally Barred
   In Harris’ second motion for postconviction relief, he
alleged that if his trial attorneys knew about Allgood and his
contacts with Hicks or about the statements that Hicks made
to McClinton, then they provided ineffective assistance in
failing to call Allgood and McClinton as witnesses. The court
found that Harris’ attorney did not know about information
that Allgood or McClinton possessed. That finding was not
clearly wrong, and Harris does not argue otherwise. Instead,
he argues that his attorney was ineffective in failing to investi-
gate the significance of Allgood after the prosecutor endorsed
him as a witness and then stated that she would not call him
to testify. This claim was available to Harris when he tendered

his third amended motion, but he did not raise it. It is now
procedurally barred.60
                       VI. CONCLUSION
   We conclude that the court properly denied relief on Harris’
claim that the State suppressed evidence of McClinton’s state-
ments in his affidavit. We conclude that the court applied the
wrong standards in denying Harris relief on his claim that the
State suppressed Allgood’s statements to police by focusing
only on the prosecutor’s knowledge of Allgood’s statements,
by failing to consider whether Allgood’s statements would
have impeached Hicks’ credibility, and by failing to examine
whether Allgood’s statements were material in the light of the
trial evidence. Finally, the court erred in failing to accurately
set forth which motion for postconviction relief it intended
to address.
   If the court concludes that the State suppressed material
evidence regarding Allgood’s statements to police or Hicks’
plea agreement, it must evaluate the materiality of that sup-
pression cumulatively. That is, the prejudicial effect of any new
suppression must be considered cumulatively with the State’s
known suppression of the Cass report.
