OPINION
COCHRAN, J.,
delivered the opinion of the Court
in which KELLER, P.J., and WOMACK, JOHNSON and ALCALA, JJ., joined.
The State of Texas, acting through Craig Watkins, the elected District Attorney of Dallas County, filed a petition for a writ of mandamus and prohibition to require the trial judge in this pending retrial of a capital murder to vacate his order precluding the State from seeking the death penalty. Jonathan Bruce Reed, the defendant and real party in interest, filed a “Motion to Preclude the Death Penalty Because the Delay Caused by the State’s Misconduct has Made a Constitutionally Adequate Sentencing Investigation Impos[495]*495sible.” After several evidentiary hearings, the trial judge — the Respondent — granted that motion. Because we conclude that the trial judge does not have the legal authority to preclude the State from seeking the statutorily authorized punishment of death set out in Article 37.0711 under these circumstances, we conditionally grant mandamus relief.
I.
A. The Trial
1. Facts
In 1979, a jury convicted Reed of capital murder by intentionally killing Wanda Wa-dle during a robbery or aggravated rape. The trial judge sentenced him to death, but then granted Reed’s motion for new trial without explanation. A second jury convicted him of capital murder in 1983, and once again he was sentenced to death.
The evidence from that second trial2 showed that Wanda Wadle shared a Dallas apartment with her sister and a friend, Kimberly Pursley. All three were flight attendants for Braniff. On November 1, 1978, Kimberly came home from a lunch with her father and noticed Wanda’s suitcase near the front door and her purse lying on the sofa with its contents scattered about. She concluded that Wanda had returned home sooner than expected from her last flight. Kimberly then heard a male voice coming from behind a closed bedroom door: “Don’t come in here. Stay out there.” Thinking that the man was a friend of Wanda’s, she said, “Don’t worry, I won’t come in.”
Soon Reed opened the bedroom door. Kimberly saw him leaning through the doorway with one hand on the molding and snapping a knife sheath closed with the other. He said, “I’m with maintenance; I came to check and change the air conditioner filters,” and he pointed toward the bedroom ceiling. Kimberly looked into the bedroom and saw Wanda’s nude body protruding spread-eagle from beneath the bed. As she turned toward Reed, he grabbed her by the throat with both hands and threw her to the living room floor on her stomach, saying “Don’t move or I’ll break your f ... ing neck.”
Kimberly heard Reed rummaging through the bedroom and then he returned and gagged her with a Braniff uniform sash, tied her hands with a leather belt, and covered her head with an apron. He then asked her, “Do you have any money?” She indicated that she did, so he took $20 from her purse and rummaged through the apartment some more. Reed then returned to Kimberly, straddled her with his legs, and began choking her with both his hands. She feigned unconsciousness. He finally stopped choking her and left.
Kimberly then ran screaming out of the apartment to find help. One neighbor found Wanda lying naked on her back with her legs spread apart. The neighbor pulled Wanda out from under the bed, removed a plastic bag and belt from around her neck, and began CPR, but Wanda died nine days later without regaining consciousness. Two neighbors had seen Reed in the complex shortly before the attack, and a maintenance man, who had seen him after the attack, identified Reed, as did Kimberly.
Reed testified at trial and presented an alibi defense. At the punishment phase, Reed presented four types of mitigating [496]*496evidence: (1) his prior good conduct in prison in which he had earned a G.E.D. and completed twenty-two hours of college credits; (2) evidence of a history of nonviolent prior crimes (including evidence that Reed was the leader and director of a “pack of juveniles” who committed a string of fifteen to twenty home burglaries in 1978) which, it was argued, demonstrated that he was unlikely to be violent in the future; (3) his turbulent family background (including evidence that he did not finish high school, that he went to the penitentiary at age nineteen, that his stepmother married his father when Reed was twenty-four, and that he had no permanent home at the time of the murder); and (4) psychiatric experts who said that, even if Reed had a “sexually deviant, anti-social personality disorder,” he would experience a violence “burnout” between the ages of thirty and forty.
2. Jury Selection
During the 1983 trial, Reed’s counsel objected to the prosecutor exercising peremptory challenges against five African-Americans.3 When the prosecutor struck the very first venireperson, Ms. Osby, the defense wanted the prosecutor to state his reason for doing so, because he “believe[d] it was done strictly for discriminatory and racial reasons.” The trial judge told counsel that, in light of his understanding of the law, he could not order the State to do that because they were free to exercise their challenge for “any reason whatever.” 4 The prosecutor then responded, saying (1) the law did not require him to give any reason for exercising a peremptory challenge; (2) he “did not exercise a peremptory because of her being a black female”; and (3) the defendant was not black. The trial judge then asked defense counsel to provide him with caselaw from “Texas or some federal jurisdiction” that supported his position. Defense counsel did not provide any authority then or later during the trial. He objected to the State’s peremptory challenges to four other black venirepersons as well.
B. The Appeals: 1983-2009
After Reed was convicted and sentenced to death, he appealed to this Court. During the pendency of that appeal, the United States Supreme Court decided Batson v. Kentucky,5 in which the Court held that the State may not use peremptory challenges solely on account of the juror’s race or on the assumption that black jurors as a group will be unable to impartially consider the State’s case against a black defendant.6 Thus, once the defendant made a prima facie showing of racial discrimination, the State was required to come forward with a race-neutral reason for that challenge.7 But Batson did not deal with [497]*497Reed’s situation because he was white and Batson, on its face, applied only to the exclusion of black jurors in a case against a black defendant. This Court did not address Reed’s Batson claim until after the 1991 Supreme Court decision, Powers v. Ohio,8 ruling that a defendant had standing to object to raced-based peremptory challenges even when he was not of the same race as those jurors.9 Thus, white defendants could object to the discriminatory exclusion of black jurors, and black defendants could object to the discriminatory exclusion of white jurors.10 Based on these two new decisions, this Court abated Reed’s appeal in late 1992 and remanded it to the trial court to conduct a retroactive Batson hearing. By then — ten years after the trial — neither the prosecutor nor the trial judge had any independent memory of the voir dire or jury selection.11 Both the trial judge and the prosecutor read and referred to the voir-dire transcript for the five challenged venire persons.12 For each of the five, the State gave race-neutral reasons for striking that juror, and the trial judge accepted those reasons as being both credible and racially neutral. When the case returned to this Court, we upheld the trial judge’s ruling and rejected Reed’s Batson claims, along with his other points of error.
After this Court affirmed Reed’s conviction and sentence in 1995, the Supreme Court denied certiorari in 1996.13 Reed then filed an application for a post-conviction writ of habeas corpus in the convicting court, and we adopted the judge’s findings of fact and denied relief in 1998.14 In 1999, the United States Supreme Court again denied certiorari.15
Later in 1999, Reed filed a petition for writ of habeas corpus in the federal district court. He included his Batson claim that the trial judge and this Court had previously rejected on direct appeal. The [498]*498magistrate judge recommended that relief be denied and, on February 19, 2003, the district judge agreed. Reed filed a motion to disqualify the magistrate, which was granted, and the Fifth Circuit later abated the case for a new federal district judge to reconsider Reed’s claims. That judge denied all of Reed’s claims on July 26, 2005, but he granted a Certificate of Appealability on the Batson claim.
Three years later, the Fifth Circuit concluded that, based upon Miller-El v. Dretke,16 an intervening 2005 decision by the Supreme Court, Reed was entitled to relief on his Batson claim.17 Miller-El allowed the federal reviewing courts to use a comparative analysis of the voir dire of all of the prospective jurors in analyzing a state-court Batson claim even though the state trial judge had never been requested to do so and the state court had not done so on direct appeal.18 The Fifth Circuit noted that although “we do not relish adding a new chapter to this unfortunate story more than thirty years after the crime took place, we conclude that the Constitution affords Reed a right to relief.”19 On January 12, 2009, the Fifth Circuit ordered that Reed be released or retried on the 1978 capital murder charges.
II.
In his pretrial motion, Reed complains that the State should not be allowed to seek the death penalty in the retrial because it was the State’s fault that it took thirty years for the appellate orbit to play itself out in his favor and, in the meantime, some potentially mitigating evidence has become unavailable. Some witnesses have died and some records from his childhood have been destroyed or lost. Reed argues that, “in the unique factual circumstances of this case, no verdict imposing a death sentence could satisfy the exacting standard of reliability imposed by the federal constitution.”20 His due process rights were violated because he could no longer mount a full defense and his attorneys could not provide effective assistance of counsel because, even with a diligent investigation, they could not bring forward mitigating evidence that no longer exists.
After several evidentiary hearings about the unavailability of certain witnesses and records, the trial judge granted Reed’s motion. He signed a fifty-two page order that concluded:
Applying all of the facts found by the Court to the legal conclusions above, the Court concludes that the Defendant’s defense team cannot conduct a constitutionally adequate mitigation investigation and that the State must therefore be precluded from seeking death in his trial.21
For legal authority, Reed relied upon a purported unpublished ruling by a Philadelphia trial court in Commonwealth of Pennsylvania v. Wilson. But Reed attached only the Pennsylvania defendant’s motion for reconsideration, which was apparently filed after the trial judge had originally denied the defense motion to preclude a capital-murder retrial. We are [499]*499unable to find any further rulings or appellate decisions in that case, but an unpublished Pennsylvania trial court ruling is not precedential authority in any event.
The State argues that the trial judge lacked any legal authority to grant Reed’s motion to preclude the State from exercising its discretionary right to seek the death penalty in this retrial. The State also argues that this very same due-process claim was rejected in 2007 by the Fifth Circuit in one of Reed’s previous federal appeals.22 The State further argues that the trial judge has, under State of Texas ex rel. Lykos v. Fine,23 unlawfully ruled upon the adequacy of Reed’s mitigation case before he has been tried, convicted, or sentenced.
Based upon the filings that are before us, we conditionally grant the State mandamus and prohibition relief because it has established both that (1) it has no other adequate legal remedy; and (2) it has a “clear right to the relief sought” and the merits of its legal position are “beyond dispute.”24
A. No Adequate Remedy at Law
Here, as in Lykos v. Fine, the State argues that it has no adequate remedy at law to correct what it contends is a legally erroneous and unauthorized pretrial advisory ruling precluding the State from seeking the death penalty in this case.25 As we have explained, the State “cannot appeal such a ruling because there is no statutory provision to allow the State to appeal such a pretrial advisory ruling.” 26 Article 44.01 simply “does not authorize the State to appeal from a pretrial ruling on a possible punishment issue that fails to dismiss any part of the actual indictment,”27 and the judge’s order in this case does not purport to dismiss any portion of the indictment. Thus, here, as in Lykos v. Fine, we conclude that a writ of mandamus or prohibition is an appropriate vehicle to review the propriety of Reed’s pretrial motion and the trial judge’s order.28
B. A Clear Right to Relief
As in Lykos v. Fine, the defendant in a pending capital-murder prosecution is attempting to prevent the State from seeking the death penalty via a pretrial eviden-tiary hearing and ruling.29 As in Lykos v. Fine, Reed is seeking a declaratory judgment that if he goes to trial, and if he is found guilty, then it would violate his constitutional rights for the State to even seek the death penalty as a sentence. Unlike the situation in Lykos v. Fine, however, Reed is not attacking the constitutionality of the Texas death-penalty statute, either facially or as applied. His claim is based solely upon specific historical facts unique to him unrelated to Article 87.071: He did not obtain relief in the appellate courts for thirty years, and, because of this lengthy delay, he has lost access to certain witnesses and documents that might have assisted him in a punishment mitigation case.
[500]*5001. The Due-Process Claim
The problem with Reed’s legal position is that the United States Supreme Court has not recognized a due-process claim that would preclude a retrial (or preclude the availability of a particular punishment) after a lengthy delay on appeal. The Fifth Circuit noted this lack of constitutional authority when it rejected Reed’s same claim in 2007. There, Reed claimed that “he was denied due process by the extended delay in the Texas Court of Criminal Appeals’ resolution of his direct appeal.”30
Of course, if this Court had resolved his direct appeal earlier (say in 1985 before Batson was decided), then his Batson claim would have been rejected out of hand because that Supreme Court ruling had not yet made new constitutional law. And, if Reed’s direct appeal were not still pending at the time Batson was decided, he also could not have obtained relief via a later writ of habeas corpus.31
Similarly, if this Court had resolved his direct appeal before the 1991 Supreme Court decision in Powers, which changed the underlying Batson rationale and focus from the defendant to the prospective jurors and allowed white defendants to assert a Batson claim when members of any distinct racial group are struck on the basis of race, Reed would not have been able to take advantage of that new aspect of Batson.
And finally, if Mr. Reed’s appeals had been completed before the Supreme Court decision in Miller-El in 2005, allowing federal reviewing courts to make a “comparative analysis” of all jurors even though the state trial judge was never asked to do so, he could not have ultimately obtained relief under that 2005 decision.
Mr. Reed’s trial and appellate attorneys should be commended for both their prescience and diligence over the long haul, but it is only because the United States Supreme Court changed the constitutional landscape over the almost thirty years that his conviction was on appeal that Mr. Reed ultimately obtained a new trial. Had the appellate process worked without delay, Mr. Reed would not be getting a second bite of the apple. In sum, this is not an instance in which the State intentionally ignored or flouted established law to obtain a conviction. This is not a case in which the trial judge ignored then-existing law. Indeed, the trial judge said that he did not have the legal authority to ask the prosecutor to explain the basis for his peremptory challenges (and he was legally correct in making that statement in 1983), but invited defense counsel to show him a case that gave him such authority.32 The present situation exemplifies the problems when the parties /and judge try a case under then-existing law only to see that law undergo dramatic changes in the full[501]*501ness of time. But, fortunately for Mr. Reed, he doggedly persevered with his various state and federal appeals until the law changed sufficiently that he was entitled to a new trial.33
But he is not entitled to more relief than a new trial. As the Fifth Circuit noted in rejecting Mr. Reed’s due-process claim, “there is no Supreme Court decision holding that excessive delay in a direct appeal is a violation of the Due Process Clause of the United States Constitution.”34 In his motion and briefs to both the trial court and to this Court, Mr. Reed has not cited a single Texas or federal case in which the State has been precluded from seeking the death penalty (or any other specific punishment) based on delay in obtaining an ultimately successful appeal.35 Indeed, the Supreme Court, in the context of a speedy trial claim, has stated that “[a] defendant with a meritorious appeal would bear the heavy burden of showing an unreasonable delay caused by the prosecution in that appeal, or a wholly unjustifiable delay by the appellate court.”36 Reed has not shown that the delay occasioned by his ultimately successful appeal was unjustifiable. He prevailed precisely because of that delay.37
[502]*5022. Unavailable Evidence Claim
Reed argues that (1) he has suffered a Sixth Amendment violation of his counsel’s investigative function because, despite their remarkable diligence, they have determined that some possibly mitigating evidence is no longer available; (2) his counsel’s inability to mount a complete defense based upon the present availability of all potential mitigating evidence violates the Eighth Amendment; and (3) the federal constitution demands consideration of mitigating evidence and without evidence of Reed’s childhood and youth no reliable sentencing verdict is possible.
The State argues that its writ petition “is not about Reed’s case in mitigation. It is about whether a trial court may preclude the death penalty for a death-eligible offense based upon a contingency.” That contingency is the assumption that Reed would be found guilty of capital murder, that a jury would find, beyond a reasonable doubt, that he would still be a future danger, and that, because some witnesses and records from his childhood and youth are unavailable, a hypothetical jury would not answer the mitigation question in his favor.
Both the State and Reed rely upon State v. Azania,38 a decision by the Indiana Supreme Court that is analogous to the present ease. In Azania, the defendant was convicted of a 1981 capital murder. The state supreme court set aside the recommendations of two juries that Azania should receive the death penalty. The trial court then ruled that, given the twenty-five year appellate delay in the case, Azania’s constitutional rights to a speedy trial and due process would be violated if the State continued to seek a death sentence.39 The Indiana Supreme Court, in an interlocutory appeal by the State,40 disagreed and found that “neither the delay nor any prejudice that Azania may suffer from it violates his constitutional rights.”41 Thus, the State could continue to seek the death penalty.
The Court noted that Azania’s claim appeared to be a “novel” one in capital litigation, but it noted that two other state courts had rejected similar claims with little discussion.42 The Indiana Supreme Court noted that delay “ ‘may work to the accused’s advantage,’ ” especially in capital litigation.43 The court held that, because most of the delay was occasioned by Azania’s appeals (which he bore the burden of going forward with) and he made no show[503]*503ing that the State affirmatively “hampered his ability” to prosecute those appeals, it would not attribute any delay in the appellate process to the State.44
Azania, like Reed, claimed that the twenty-five-year delay had resulted in the unavailability of important mitigation witnesses.45 But, as the court noted, many of the State’s witnesses were also now unavailable, and the State bears the burden of proof at the guilt stage, and it must also prove, beyond a reasonable doubt, the aggravating circumstances during the punishment phase. While the unavailability of the defense witnesses and evidence “may make it more difficult for Azania to defend against the State’s case, we find that it creates far greater difficulty for the State to meets its burden of proof.”46 The Azania court noted that the Supreme Court has said that “ ‘delay is a two-edged sword. It is the Government that bears the burden of proving its case beyond a reasonable doubt. The passage of time may make it difficult or impossible for the Government to carry out this burden.’ ”47 The same is true in the present case.
Reed offered significant mitigation evidence in the 1983 trial and, if the witnesses who testified at that trial are presently unavailable, he may offer their former testimony.48 Reed argues that many of his school records, psychiatric records, and TYC records are no longer available simply because of the passage of so much time.49 But that would likely be true for any sixty-year-old defendant in a capital-murder trial. The fact that Reed might not be able to present his mitigation case (if he is found guilty in the retrial) in precisely the form he would prefer does not violate his constitutional rights.50
The evidentiary hearings on Reed’s motion focused solely on evidence that Reed says he cannot now present, not on what evidence was still available or what evidence is now available that did not exist at the time of the 1983 trial. Nor did those hearings develop how certain “missing” primary evidence could be presented in another form or through other witnesses. To the extent that the trial judge’s factual findings are based on those evidentiary hearings, they are incomplete and largely hypothetical.
Furthermore, not all mitigation evidence is created equal. While evidence of childhood difficulties, a turbulent upbringing, youthful crimes and psychiatric diagnoses are certainly relevant and admissible in [504]*504the punishment phase of a sixty-year-old man (should there be a verdict of guilty), that evidence might pale in significance to the evidence of more recent behavior, beliefs, and attitudes. A young man with a long record of adolescent crime (such as Reed had) may have to rely upon explaining the genesis and rationale for that conduct and hope that the jury may sympathize with his incorrigibility. An older man may show that he has changed his spots and is no longer a danger to others. For example, the psychiatrists testified in the 1988 trial, that even a “sexually deviant” man with “anti-personality disorder” would experience a violence “burnout” between the ages of thirty and forty. Reed now has available evidence of the past thirty years in which his character may have altered dramatically for the better. Evidence of present rehabilitation, redemption, and remorse may be significantly more powerful mitigation evidence than tales of a troubled childhood some forty to fifty years ago. Reed now has the opportunity to persuade the jury that he has risen, like Phoenix from the ashes, and become a wholly different person than the man he was in 1978.
It is the State’s burden to prove that Reed would still constitute a future danger to society, and that would be a heavy burden under these circumstances. Neither Reed nor the State bear an evidentia-ry burden on the mitigation issue, and Reed may mount a most compelling case for mitigation as a sixty-year-old man who has overcome his prior problems and made some contribution to his society in the intervening years of reflection.51 Given the diligence of his resourceful counsel, we do not doubt that he would be able, if necessary, to mount an effective mitigation case, and that a jury would make appropriate allowance for records and witnesses that are no longer available.52
More importantly, the issue of the adequacy of Reed’s mitigation case is not ripe for review. The Supreme Court has held that the ripeness doctrine protects against “judicial interference until a[ ] ... decision has been formalized and its effects felt in a concrete way by the challenging parties.”53 To decide whether an issue is ripe for adjudication, we must “evaluate both the fitness of the issues for judicial decision and the hardship to the parties of withholding court consideration.” 54
The issue of the adequacy of Reed’s mitigation case is not “fit” for judicial decision before it is presented. Here, a capi[505]*505tal-murder defendant is seeking a pretrial declaratory judgment that any mitigation case that he might mount would necessarily be inadequate and therefore any prospective death sentence would, if it occurred, violate the Eighth Amendment, the Sixth Amendment, and the Due Process Clause. “These assumptions are simply not warranted before a jury has considered the evidence in the present case and rendered a verdict.”55 We do not put the cart before the horse: “a defendant has no claim of wrongful conviction or wrongful sentencing before he has even gone to trial.”56 The adequacy and efficacy of Reed’s mitigation case cannot be judged unless he has actually been convicted of capital murder and sentenced to death.57 Any pretrial determination of that mitigation case is necessarily hypothetical and unlikely to fairly reflect reality as it plays out in an actual trial. As we explained in Lykos v. Fine,
A trial on the merits is “the main event” in our American system of justice in which the prosecution and defense present evidence and do battle to reach a presumptively accurate and reliable result in each particular case. At that trial on the merits “[i]f a criminal defendant thinks that an action of the state trial court is about to deprive him of a federal constitutional right there is every reason for his following state procedure in making known his objection.”58
Finally, the dissent argues that Reed’s due-process claim is analogous to that involving a pretrial challenge to an indictment based on a speedy-indictment claim. As Judge Keasler aptly points out in his concurring opinion, this situation is not analogous to that situation. In United States v. Marion,59 the Supreme Court noted that
[T]he Government concede[d] that the Due Process Clause of the Fifth Amendment would require dismissal of the indictment if it were shown at trial that the pre-indictment delay in this case caused substantial prejudice to appel-lees’ rights to a fair trial and that the delay was an intentional device to gain tactical advantage over the accused.60
That is a two-pronged test: First, the defense must show at trial that the delay did, in fact, cause substantial prejudice to his right to a fair trial;61 and second, the [506]*506defense must show that the government intentionally delayed its indictment for the purpose of gaining a tactical advantage over the defendant.62 It is only after the defendant has shown actual — not possible or potential — prejudice that adversely affected his defense, that the due process issue is ripe for adjudication.63 As discussed above, Reed has not shown any actual and substantive prejudice to his mitigation case because he has not yet presented it. Second, as a matter of law, Reed cannot demonstrate that the State intentionally or purposely delayed the appellate process in this case for the purpose of gaining a tactical advantage over him in a retrial.64 It was Reed, not the State, who invoked those appellate procedures, and there has been no showing that the State acted in bad faith in its appellate duties.65 It cannot be persuasively argued that the State could have, or should have, predicted the dramatic changes in the law concerning peremptory challenges between 1983 and 2005. The pre-indictment delay cases provide no support for addressing or ruling on Reed’s due-process claim in a pretrial setting.
In sum, Reed has failed to offer any legal precedent or lawful authority which would support a pretrial declaratory judgment that the State should be forbidden from seeking the death penalty in a capital-murder trial when some potentially useful records and witnesses are no longer available.66 Because there is no basis under Texas law to conduct a pretrial eviden-tiary hearing to determine the adequacy of a mitigation case in a capital-murder proceeding, we conclude that the trial judge does not have legal authority to conduct such a hearing or make such a declaratory judgment. As in Lykos v. Fine, “[h]e is acting beyond the scope of his lawful au[507]*507thority.”67
Therefore, the State has demonstrated a clear right to relief. We conditionally grant a writ of mandamus68 and direct the Respondent, the Honorable John Creuzot, to vacate and withdraw his order of April 20, 2011 precluding the State from seeking the death penalty in this case. The writ of mandamus from this Court will issue only if the Respondent fails to comply with this Court’s directive.
