Jason Dirk Walton appeals an order of the Circuit Court of the Sixth Judicial Circuit summarily denying his successive motion to vacate three convictions of first-degree murder and corresponding death sentences under Florida Rule of Criminal Procedure 3.851. Under our mandatory jurisdiction to review orders arising from capital proceedings, we affirm the circuit court’s order. See art. V, § 3(b)(1), Fla. Const.
In his first claim, Walton has failed to demonstrate that the State violated his constitutional rights by utilizing inconsistent theories to secure convictions against each of the criminal defendants in this triple homicide. Walton also has not established prejudice from the alleged use of a state agent, who did not testify in his second sentencing proceeding. Next, the trial court properly denied Walton’s motion for additional public records because each request was either overbroad, collateral, or irrelevant to his postconviction claims. Lastly, this Court has previously considered and repeatedly rejected the evidence presented by Walton in support of his challenge to the constitutionality of Florida’s lethal injection protocol. Thus, for the reasons explained below, we affirm the circuit court’s order summarily denying postconviction relief.
I. PROCEEDINGS TO DATE
A. Conviction and Sentencing
In 1984, Jason Dirk (J.D.) Walton was convicted of three counts of first-degree murder in Pinellas County.
See Walton v. State,
Walton made two statements to the police in which he admitted being present at the time of the homicide but denied any part in the shootings. See id. He told police that although he initiated the idea to commit the intended crime, he tested his handgun before entering the house and it had misfired. See id. He observed Van Royal and Cooper pointing shotguns at the victims. As Walton exited the house, he heard several gunshots. See id.
The jury found Walton guilty of all three counts of first-degree murder. See id. During the first penalty phase, the State introduced the testimony of an alleged jailhouse informant and former cellmate of codefendant Cooper. See id. at 1198-99. The cellmate testified that Cooper had indicated Walton was the “ringleader” and had informed Cooper that the codefen-dants were going to “eliminate” the victims. Id. The State also introduced the written confessions of Cooper and McCoy. See id. at 1198. Following the jury recommendation, the trial court imposed a death sentence for each murder. On direct appeal, this Court affirmed the convictions but reversed the death sentences and remanded for a new sentencing hearing because the written confessions constituted hearsay and thus were admitted in violation of Walton’s confrontation rights. See id. at 1200-01.
During the second sentencing hearing, the State did not introduce the written confessions or the testimony of the jailhouse informant. Instead, it again presented Walton’s confession, including the statement that Walton “turned on the television full blast to prevent the neighbors from hearing the victims scream and that he heard shotgun blasts as he left.”
Walton II,
B. Rule 3.850 and Habeas Proceedings
Governor Martinez signed a death warrant for Walton on September 24, 1990, and denied Walton’s request for clemency. Thereafter, this Court granted a stay of execution for Walton to file his first rule 3.850 motion to vacate his convictions and sentences. The trial court denied Walton’s ensuing motion.
2
In the same
*1004
year, Walton filed a petition for writ of habeas corpus in this Court, in which he claimed error in the penalty phase jury instructions and presented other claims that were also concurrently presented in his motion to vacate.
3
On appeal of the order denying the rule 3.850 motion, Walton contended that the circuit court erred when it denied his claim that the prosecutor had utilized inconsistent theories in securing the death sentences against him, which violated his rights under
Brady v. Maryland,
Subsequently, Walton filed his Third Amended Motion to Vacate based on newly discovered evidence found during the public records litigation. In this motion, it appears that Walton retooled his inconsistent theories claim as an ineffective assistance of counsel claim. The circuit court denied the motion after an evidentiary hearing. On appeal, Walton raised several additional claims.
4
This Court affirmed the order and denied the habeas petition.
See Walton IV,
C. Successive Postconviction Proceedings
In 2006, Walton filed a successive motion for postconviction relief based on the discussion of inconsistent prosecutorial theories in
Bradshaw v. Stumpf,
II. ANALYSIS.
A. The State Did Not Use Inconsistent Theories to Secure Death Sentences Against All Codefendants.
In
Bradshaw v. Stumpf,
A successive rule 3.851 motion may be denied without an evidentiary hearing if the records of the case conclusively show that the movant is entitled to no relief.
See
Fla. R.Crim. P. 3.851(f)(5)(B). This Court reviews the circuit court’s decision to summarily deny a successive rule 3.851 motion de novo, accepting the movant’s factual allegations as true to the extent they are not refuted by the record, and affirming the ruling if the record conclusively shows that the movant is entitled to no relief.
See State v. Coney,
The record conclusively demonstrates that Walton is not entitled to relief because this claim is procedurally barred and meritless. Florida Rule of Criminal Procedure 3.851(d)(2)(B) requires any motion to vacate judgment of conviction and death sentence to be filed within one year after the judgment and sentence become final unless the motion alleges that a fundamental constitutional right, held to apply retroactively, was established after that period. Thus, as the circuit court determined, Walton’s claim is procedurally barred because the
Bradshaw
Court did not recognize a new fundamental constitutional right that applies retroactively.
See Van Poyck v. State,
Rather, the United States Supreme Court specifically declined to rule on the question of whether the prosecutor’s use of inconsistent theories constituted a due process violation.
See Bradshaw,
Additionally, Walton concedes that he had previously raised versions of this claim in his initial and third motions to vacate, belying any assertion that this is a newly discovered error.
See Walton IV,
[ejvidence introduced at Walton’s trial showed that Walton originated the plan to rob the victims on a rainy night, Walton armed the group prior to the [episode], and Walton was the only defendant involved who knew the location of the victims’ house. In the face of this overwhelming evidence, it is clear that the introduction of two statements by a state attorney in a codefendant’s trial would not have been overly persuasive. Certainly, non-introduction of this evidence does not undermine our confidence in the outcome.
Id. (citation omitted). Thus, this Court has already determined that the alleged inconsistent statements are neither persuasive nor do they undermine our confidence in Walton’s convictions and sentences. This claim is therefore procedurally barred because Walton has failed to demonstrate a basis for escaping the one-year time limitation on raising the issue.
Even if this claim did not face a procedural bar, it would still fail because the State advanced a wholly consistent theory of the crime in prosecuting the codefendants. The prosecutorial theory that Walton was the ringleader and that Cooper and Van Royal were the primary shooters is neither a differing nor an irreconcilable rendition of the factual scenario. In contrast, the State in
Fotopoulos
clearly advanced inconsistent positions, asserting in codefendant Deidre Hunt’s case that she was an independent actor voluntarily participating in the murders, yet presenting the central theory in Fotopoulus’s trial that Hunt was dominated by Fotopoulos.
See Fotopoulos,
In
Raleigh v. State,
A comparison of the challenged statements in Cooper’s sentencing hearing with those at Walton’s hearing confirms the cohesion of the State’s theory. At Cooper’s hearing, the State said that Cooper
was ready, posed and willing with his finger on the trigger and he made the decision to pull that trigger and to cock it and to pull the trigger again, and aimed it at a second victim and to cock it again and pull the trigger again and aim it at a third victim and then to reload either the last shot or the fourth shot and to come back in the house and pull the trigger again and then cock it again and eject the shell inside the house.
In Walton’s hearing, the State argued: “J.D. took the handgun, typically he had other peaple do the dirty work, but unquestionably, he ivas the ringleader, he was the planner, he was the prime mover among these younger individuals.” (Emphasis supplied.) In direct comparison, these statements show the underlying principle and theme that Walton was the ringleader and that Cooper ultimately pulled the trigger.
As an aside, Walton has claimed that this scenario was a “total fiction.” However, Walton’s own confession, along with the other facts presented during the sentencing hearing, corroborates the State’s theory that Walton organized the criminal episode. Therefore, the State did not take an inconsistent position or “change course” in its theory.
Raleigh,
B. Any Possible Error in the Alleged Failure to Disclose the Use of a State Agent in the Sentencing Hearing that Resulted in the Death Sentence That Was Later Vacated Did Not Prejudice Walton.
Walton next contends that the State withheld material and exculpatory evidence tending to prove that a witness— who did not testify during either the guilt phase of the trial or the resentencing hearing — was a state agent, in violation of
Brady v. Maryland,
i. Newly Discovered Evidence Claim
Walton contends that these affidavits constitute newly discovered evidence that the State utilized a state agent to secure incriminating evidence against him and that they lend further support to his
Brady
and
Giglio
claims. To obtain a new trial based on newly discovered evidence, a defendant must meet two requirements: First, the evidence must not have been known by the trial court, the party, or counsel at the time of trial, and it must appear that the defendant or defense counsel could not have known of it by the use of due diligence. Second, the newly discovered evidence must be of such nature that it would probably produce an acquittal on retrial.
See Jones v. State,
Under this second prong, Walton has failed to demonstrate that these affidavits constitute evidence of such a nature that it would probably produce an acquittal on retrial. To the extent the affidavits suggest that the informant may have assisted as a state agent, they do not outweigh the strong evidence of Walton’s role in the triple homicide, which this Court has affirmed.
See Walton I,
Even though the informant was not presented as a witness during either the guilt phase of the trial or the resentencing hearing, Walton further asserts that the informant’s testimony nevertheless “contaminated” the resentencing hearing because the resentencing court included small details about the commission of the crime, such as Walton grabbing the victim’s hair, that were presented only in the informant’s prior testimony. Within the context of an ineffective assistance of counsel claim in Walton’s prior appeal, however, this Court rejected the “contamination” argument:
Walton seizes upon the trial court’s determination in its order that “Walton grabbed one of the victims by the hair,” in an attempt to show that the entire resentencing was tainted with evidence from the previous penalty phase reversed in Walton I. The State cannot identify any source for this information, and there is seemingly no record material from the resentencing proceedings which supports this statement by the trial court. While this presents questions, the inclusion of one errant phrase by the trial court in its sentencing order is not significant evidence that the trial court relied upon the original confessions of McCoy and Cooper [and, thus, the testimony of the informant who corroborated these confessions] in sentencing Walton to death. Clearly, taken in conjunction with the presence of overwhelming evidence before the court supporting its conclusions as to Walton’s leadership role in the burglary planning, this mistaken statement by the trial *1009 court within its final order was harmless. Certainly, the trial court’s final sentencing decision did not hinge upon whether Walton actually placed his hands upon a victim’s hair or not. Thus, this error did not contribute to Walton’s sentence, and we conclude that it was harmless under State v. DiGuilio,491 So.2d 1129 (Fla.1986).
Walton IV,
ii. Brady Claim
Furthermore, these affidavits do not establish Walton’s claim of a
Brady
violation. Nothing in the record regarding the alleged informant’s speculative use as a state agent undermines our confidence in the verdict or sentences rendered to meet the materiality prong of
Brady.
The State is required, under
Brady,
to disclose material information within its possession or control that is favorable to the defense.
See Mordenti v. State,
iii. Giglio Claim
Moreover, the State did not present any testimony from the alleged informant during the guilt phase of the trial or the resentencing hearing, which leaves no reasonable possibility that the use of this testimony could have affected the outcome pursuant to
Giglio.
To establish a
Giglio
violation, it must be shown that: “(1) the testimony given was false; (2) the prosecutor knew the testimony was false; and (3) the statement was material.”
Guzman v. State,
We affirm the circuit court’s summary denial of this claim because the purported newly discovered evidence of a Brady or Giglio violation lacks any reasonable probability to undermine our confidence under Brady or any reasonable possibility that it could have affected the jury’s verdict or recommendation of a death sentence under Giglio. Furthermore, the affidavits do not constitute newly discovered evidence of such a nature that it would probably produce an acquittal on retrial. Therefore, this claim must also be denied.
iv. Public Records Request
In conjunction with this claim, Walton sought additional public records from the Office of the State Attorney. Walton requested all records, files, documents, notes, pleadings, memoranda, and attorney work product relating to eodefendant Cooper’s postconviction proceedings. He also desired access to all records, files, documents, notes, pleadings, memoranda, statements, and transcripts relating to the jailhouse informant where he was either a party or a witness. The circuit court denied the motion for the informant’s records because they were previously requested by defense counsel in 1993 and 1995 and determined to be statutorily exempt from production. With regard to Cooper’s documents, the circuit court found no indication that the information in a collateral, unrelated proceeding had any bearing on Walton’s current motion or that the records were relevant or reasonably calculated to lead to the discovery of admissible evidence in Walton’s postconviction proceeding.
This Court reviews the trial court’s denial of a public records request for abuse of discretion.
See Diaz v. State,
(A) collateral counsel has made a timely and diligent search of the records repository;
(B) collateral counsel’s affidavit identifies with specificity those additional public records that are not at the records repository;
(C) the additional public records sought are either relevant to the subject matter of a proceeding under rule 3.851 or appear reasonably calculated to lead to the discovery of admissible evidence; and
(D) the additional records request is not overly broad or unduly burdensome.
A review of Walton’s February 13, 2006, demand reveals that competent, substantial evidence supported the trial court’s exercise of discretion to deny the requests.
After an in-camera review by the circuit court in 1995, it was determined that the jailhouse informant’s files were statutorily exempt from production under chapter 119, Florida Statutes (1995). See also Fla. R.Crim. P. 3.852(0(1) (limiting the scope of production to records that are not privileged or immune from production). Even without these exemptions, Walton’s demand does not demonstrate how the documents would be reasonably calculated to lead to relevant information because the informant, as repeatedly noted, did not testify during Walton’s second sentencing proceeding. Walton also has not shown any change in circumstance from the circuit court’s 1995 ruling.
Lastly, Walton’s demand appears to be an “overly broad or unduly burdensome” fishing expedition seeking any and all records from more than thirty irrelevant, collateral cases unrelated to Walton’s post-conviction claim. See Fla. R.Crim. P. 3.852(i)(2)(D). To delve so deeply into collateral matters, Walton must explain, at a *1011 minimum, how that information would lead to evidence related to Walton’s claim. See Fla. R.Crim. P. 3.852(i)(1)(C), (2)(D). Walton did not demonstrate that discovery of the codefendant’s postconviction documents, the boxes of material relating to the informant in the federal court order, the case files in which the informant was a defendant, and the cases where, “based on the best information that was available, counsel believed ” that the informant was a state witness, would reasonably lead to evidence that would support his postcon-viction claim. The informant did not testify during Walton’s resentencing hearing, and this Court does not deem any evidence corroborating the informant’s purported status as a state agent to be material to the sentences imposed on remand. Likewise, the codefendant’s Brady claim in federal court has no bearing on Walton’s present motion. We therefore affirm the circuit court’s order denying the demand for production because the record supports its appropriate exercise of discretion.
C. Lethal Injection Claims.
i. The Lancet Article and Diaz Execution
Next, Walton challenges the constitutionality of Florida’s lethal injection protocol under the Eighth Amendment of the United States Constitution. The issue presented to the trial court in Walton’s postconviction motion was whether the study published in
The Lancet, Inadequate Anaesthesia in Lethal Injectiim for Execution,
constituted newly discovered evidence.
See
Leonidas G. Koniaris et al.,
Inadequate Anestltesia in Lethal Injection for Execution,
365 Lancet 1412 (2005). In summarily denying this claim, the circuit court ruled that it was bound by our decisions in
Diaz v. State,
On appeal, Walton appears to withdraw from any reliance upon
The Lancet
study. Instead, Walton now asserts that the circuit court erred in prematurely denying his successive motion before he had the opportunity to file a motion to amend his claim, which he did not intend to file until after the issues surrounding the Diaz execution were resolved. Reviewing the time-line of events, the Diaz execution occurred in early December 2006. In response, Walton moved to continue the case management conference scheduled for late December 2006. The circuit court granted this motion and rescheduled the conference for mid-January 2007. In February 2007, this Court dismissed without prejudice Walton’s petition in
Lightbourne v. McCollum,
Thus, from December 2006, at the earliest, and by March 2007, at the latest, Walton was on notice to amend his motion to include any claims regarding the Diaz execution. Walton did not, however, attempt to supplement his motion based on *1012 the Diaz execution and the subsequent remedial measures. In his motion for rehearing, filed in late-March 2007, Walton’s counsel sought for the first time leave to amend his lethal injection claim based on newly discovered evidence premised upon the events surrounding the Diaz execution. In essence, Walton now contends that the trial court erred by not holding the disposition of his successive postconviction motion in abeyance until some unknown time when he was ready to file an amendment to his lethal injection claim.
We review the denial of a motion to amend a postconviction motion for abuse of discretion.
See Huff v. State,
Furthermore, even if we considered the merits, this Court has continually upheld the constitutionality of Florida’s lethal injection protocol since the issuance of
Lightbourne. See Tompkins v. State,
The research study in
The Lancet
does not constitute newly discovered scientific evidence that Florida’s lethal injection protocol creates a substantial, foreseeable, or unnecessary risk of pain for the condemned.
See Rutherford,
*1013 Moreover, we have rejected contentions that Baze set a different or higher standard for lethal injection claims than Lightbourne. See, e.g., Henyard, [992 So.2d at 129 ] (rejecting Henyard’s argument that Baze sheds new light on this Court’s decisions because the standard for reviewing Eighth Amendment challenges was changed and noting that “[w]e have previously concluded in Lightboume and Schwab that the Florida protocols do not violate any of the possible standards, and that holding cannot conflict with the narrow holding in Baze ”). The second development was the performance of two executions in Florida, those of Mark Dean Schwab and Richard Henyard, with no subsequent allegations of any newly discovered problems with Florida’s lethal injection process, such as the problems giving rise to the investigations following the Diaz execution.
Tompkins,
ii. The ABA Report
Walton has separately asserted that the ABA report entitled
Evaluating Fairness and Accuracy in the State Death Penalty System: The Floñda Death Penalty Assessment Report,
published September 17, 2006, constitutes newly discovered evidence which reveals that the imposition of the death penalty constitutes cruel and unusual punishment in violation of the Eighth Amendment. Just as this Court has previously considered
The Lancet
report, we have also reviewed the ABA report and concluded that it does not constitute newly discovered evidence because the report is “a compilation of previously available information related to Florida’s death penalty system and consists of legal analysis and recommendations for reform, many of which are directed to the executive and legislative branches.”
Rutherford v. State,
Though Walton attempts to allege that the report’s conclusions render his individual death sentence unconstitutional, the specific allegations in his motion merely refer to generalities that are noted in the report but do not relate in any specific way to Walton’s death sentence.
See Tompkins,
iii. Request for Additional Public Records Relating to Lethal Injection
In his motion for production of public records to support his claim that lethal injection constitutes cruel and unusual punishment, Walton sought “all information that in any way related to lethal injection,” specifically enumerating an additional sixty-one documents or categories of documents relating to execution by lethal injection. Walton’s request was made pur
*1014
suant to Florida Rule of Criminal Procedure 3.852(i), which limits postproduction requests for additional records. The record conclusively demonstrates that the circuit court did not abuse its discretion in denying this claim because the records requested were neither relevant nor reasonably calculated to lead to the discovery of admissible evidence for this claim.
See
Fla. R.Crim. P. 3.852(i)(2)(C) (requiring production of records upon finding that the additional records sought are either relevant or reasonably calculated to lead to the discovery of admissible evidence). Foremost, as explained in connection with our discussion of lethal injection, production of these records is unlikely to lead to a color-able claim for relief because the challenge to the constitutionality of lethal injection as currently administered in Florida has been fully considered and rejected by the Court.
See Tompkins,
Accordingly, for the reasons set out above, we affirm the trial court’s summary denial of Walton’s successive postconviction motion.
It is so ordered.
Notes
. Further factual details can be found in the Court's previous decisions addressing Walton's capital proceedings.
See Walton v. State,

health expert; (5) suppression of statements; (6) absence of Walton from a portion of the proceedings; and (7) application of Florida Rule of Criminal Procedure 3.851.
See Walton IV,
.Walton's habeas petition alleged ten claims, including: (1) new law mandated reconsideration of his original evidentiary claims; (2) unconstitutional procedures in Florida’s system of capital sentencing; (3) errors in proportionality and aggravating circumstances; and (4) prejudicial admission of evidence of collateral crimes.
See Walton IV,
. Walton’s appeal added the following claims: (1) counsel failed to adequately investigate and prepare for trial; (2) violation of
Brady;
