OPINION
Appellant James Lambert appeals from the order of the Court of Common Pleas dismissing his second petition for relief filed pursuant to the Post Conviction Relief Act (“PCRA”), 42 Pa.C.S. § 9541 et seq. For the reasons set forth below, we find that appellant is not entitled to relief and, accordingly, we affirm the order of the PCRA court.
On April 25, 1984, appellant was convicted of first degree murder, robbery, conspiracy, and related offenses in connection with the murders of two patrons during a robbery of a bar in Philadelphia.
1
Following a penalty-phase hearing, the jury returned a sentence of death for each murder count. On direct appeal, this Court affirmed appellant’s convictions and sentences.

A PCRA petition, including a second or subsequent petition, must be filed within one year of the date that judgment of sentence becomes final. 42 Pa.C.S. § 9545(b)(1). A judgment becomes final for purposes of the PCRA “at the conclusion of direct review, including discretionary review in the Supreme Court of the United States and the Supreme Court of Pennsylvania, or at the expiration of time for seeking the review.” 42 Pa.C.S. § 9545(b)(3). If a PCRA petition is untimely, neither this Court nor the trial court has jurisdiction over the petition.
Commonwealth v. Murray,
Here, appellant concedes that he did not file the instant PCRA petition within one year of the date that his judgment became final. Appellant contends, however, that his petition is timely as it fits within two of the three exceptions to the PCRA’s timeliness requirements provided in Section 9545(b)(1). That Section provides in full:
Any petition under this subchapter, including a second or subsequent petition, shall be filed within one year of the date the judgment becomes final, unless the petition alleges and the petitioner proves that:
(i) the failure to raise the claim previously was the result of interference by government officials with the presentation of the claim in violation of the Constitution or laws of this Commonwealth or the Constitution or laws of the United States;
(ii) the facts upon which the claim is predicated were unknown to the petitioner and could not have been ascertained by the exercise of due diligence; or
(iii) the right asserted is a constitutional right that was recognized by the Supreme Court of the United States or the Supreme Court of Pennsylvania after the time period provided in this section and has been held by that court to apply retroactively.
*467 42 Pa.C.S. § 9545(b)(1). Moreover, any petition invoking one or more of these timeliness exceptions must be filed within sixty days from the date that the claim could have been presented. 42 Pa.C.S. § 9545(b)(2).
Appellant argues that the claims raised in his serial petition fall within both the “governmental interference” exception, 42 Pa.C.S. § 9545(b)(1)®, and the “newly discovered evidence” exception, 42 Pa.C.S. § 9545(b)(1)(h), to the timeliness provision of the PCRA, because the Commonwealth withheld impeachment and exculpatory evidence, thus violating
Brady v. Maryland,
In response, the Commonwealth argues that in order for appellant’s PCRA petition to fall within the cited timeliness exceptions, he must actually establish a meritorious
Brady
claim. The Commonwealth argues that the PCRA court correctly determined that each
Brady
claim asserted by appellant was without merit and, thus, appellant’s petition is untimely. The newly discovered evidence exception, set forth in Section 9545(b)(l)(ii), however, does not require a merits analysis of the claim in order for it to qualify as timely and warranting merits review. The exception merely requires that the “facts” upon which such a claim is predicated must not have been known to appellant, nor could they have been ascertained by due diligence. Appellant asserts that the “facts” upon which his
Brady
claims are based derive from documents contained in this case’s archived police file, which were not “known” to him until after the filing of his initial PCRA petition. In accordance with this Court’s decision in
*468
Commonwealth v. Lark,
The manner in which appellant obtained the alleged impeachment and exculpatory evidence underlying his Brady claims was extraordinary. In October 2001, proceedings were commenced before the Honorable D. Webster Keogh, the Supervising Judge of the Criminal Division of the Court of Common Pleas of Philadelphia, following a formal complaint filed by the Commonwealth regarding the improper use of subpoenas by the Federal Capital Habeas Corpus Unit of the Defender Association of Philadelphia (“Federal Defender”) to obtain archived police files. At these proceedings, it was revealed that between June and October 2001, the Federal Defender improperly subpoenaed the original police files for approximately twenty-five capital cases from the Philadelphia *469 City Archivist, apparently in an effort to circumvent the discovery requirements set forth in Pa.R.Crim.P. 902(E). On October 29, 2001, Judge Keogh ordered that the archived police files obtained by the Federal Defender be sealed, thus precluding the Federal Defender from disclosing the contents of the files they unlawfully secured. In a decision letter dated February 8, 2002, Judge Keogh concluded that the Federal Defender’s actions constituted an abuse of the subpoena power to such an improper and illegal extent that he referred the matter to the Pennsylvania Disciplinary Board for appropriate action.
The original police file for the instant case was one of the archived police files obtained by the Federal Defender. In the instant serial PCRA petition, appellant’s counsel, who is not contractually or otherwise affiliated with the Federal Defender, stated that while appellant’s appeal of his first PCRA petition was pending before this Court, he became aware that the Federal Defender, who had been assisting counsel in the litigation of this case, were in possession of the original police file. Counsel was informed by the Federal Defender that the file allegedly contained unspecified
Brady
material. In accordance with
Lark,
The law governing alleged
Brady
violations is well-settled. In
Brady,
the United States Supreme Court held that “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.”
Brady,
On the question of materiality, the Court has noted that “[s]uch evidence is material ‘if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different.’ ”
Strickler v. Greene,
Importantly, the Court has noted that the duty imposed upon the prosecution under
Brady
is a limited one.
See, e.g., Weatherford v. Bursey,
As noted above, appellant raises seven Brady claims based on previously undisclosed documents found in the archived police file. In response, the Commonwealth argues that each Brady claim is meritless, and that appellant’s arguments in support of each alleged violation either mischaracterize the *472 content of the documents, or are based on mere speculation. We address each Brady claim seriatim.
Appellant first claims that the Commonwealth violated Brady by not disclosing the police activity sheet of October 25, 1982. In this document, there is a notation that Commonwealth witness Bernard Jackson, who was the getaway driver during the robbery and an original codefendant of appellant herein, named Lawrence Woodlock as a codefendant. Appellant argues that this “statement” by Jackson is exculpatory as it is evidence that someone other than himself was involved in the robbery, or at a minimum, that someone other than himself was the shooter. Appellant argues that this statement supported the defense theory that Jackson simply made up a third robber in order to reduce the culpability of codefendant Bruce Reese. Appellant further argues that this statement could have been used to impeach Jackson’s testimony at trial because it established that Jackson provided Woodlock’s name prior to identifying appellant as the third robber.
The Commonwealth counters that the “statement” by Jackson in this document was actually an “ambiguously worded notation” which simply states that Jackson had named Wood-lock as a codefendant without specifying whether he was naming Woodlock as a codefendant in this robbery or a previous robbery. The Commonwealth notes that Woodlock’s name appears nowhere else in the police files, was not mentioned by any witness at trial, and was not mentioned in any of the formal statements offered by Jackson to the police concerning the robbery. 4 The Commonwealth further notes that Jackson’s testimony was extensively impeached at trial by both appellant and codefendant Reese; therefore, the ambiguous reference to Woodlock in this document would not have discredited him any further.
*473
The PCRA court concluded that this document was not material as it did not create a reasonable probability that the result of the proceeding would have been different had it been disclosed.
Strickler,
Appellant’s next Brady claim concerns the Commonwealth’s nondisclosure of the police activity sheet of October 12, 1982. This document contains a photograph of Jackson with a handwritten notation to the right of picture stating “driver/witness not shooter by door.” Appellant concedes that the document does not reveal the source of the notation, but speculates that it might derive from a statement made by Jackson to the police, and if it was, it would directly contradict *474 Jackson’s testimony that he remained outside the bar in the car and did not witness the shootings. Appellant argues that this notation both corroborates his defense theory at trial that Jackson and Reese committed the robbery by themselves, and that it could have been used to impeach Jackson’s testimony at trial.
As both the Commonwealth and PCRA court accurately note, appellant’s interpretation of this notation is purely speculative and not supported by the record. Appellant essentially concedes as much, but nonetheless argues that the Commonwealth was obligated to disclose it, and if it had been disclosed defense investigation may have led to favorable exculpatory evidence. Neither this Court, nor the United States Supreme Court, however, have ever held that
Brady
requires the disclosure of information that is not exculpatory but might merely form the groundwork for possible arguments or defenses.
See Commonwealth v. Chambers,
Appellant claims that the Commonwealth committed a third
Brady
violation by not disclosing the police activity sheet of January 14, 1983. This document indicated that Jackson had failed a polygraph examination regarding the identity of the person who possessed the murder weapon during the robbery and which persons made incriminating statements to him following the robbery and shootings. The document further indicated that Jackson changed his story after being confronted by the police that he failed the polygraph test. The record reflects, however, that the Commonwealth disclosed to trial counsel, during pre-trial discovery, Jackson’s actual police statement from January 14,1983, which explicitly stated that Jackson failed the polygraph test and then changed his story. Thus, there was no
Brady
violation in connection to this information.
Commonwealth v. Morris,
573
*475
Pa. 157,
Appellant next claims that the Commonwealth violated
Brady
by not disclosing the police activity sheet of September 24, 1982, which indicated that an individual named Snyder informed the police that his brother had told him that Paul and Robin Adams had purchased a gun and planned to rob a bar. Upon learning of the robbery and murders at issue in this ease, Snyder speculated that the Adams’ had committed the crimes. Appellant contends that this document proves that someone other than himself committed the robbery and murders. Contrary to appellant’s assertion, the information contained in this document was not evidence that someone other than appellant committed the instant crimes. As the Commonwealth notes, the information contained in this document was an initial lead based on hearsay and speculation. As noted by this Court, the prosecution is not required to disclose to the defense “every fruitless lead followed by investigators of a crime.”
Commonwealth v. Crews,
Appellant’s next Brady claim concerns the Commonwealth’s nondisclosure of the police activity sheet of September 23, 1982, in which the police noted their intention to *476 administer polygraph examinations to the barmaids working on the evening of the robbery. Appellant speculates that this document demonstrates that the police believed these witnesses were lying or that the robbery may have been an “inside” job. Appellant’s argument as to what the police supposedly believed is based on mere conjecture and he fails to explain how this information was admissible, exculpatory, or favorable. Accordingly, this claim fails.
Appellant next claims that the Commonwealth violated
Brady
by not disclosing police composite sketches which, in appellant’s view, do not resemble appellant but, in fact, closely resemble Jackson. This claim, bottomed upon appellant’s own subjective opinion, is utterly meritless; evidence in the possession of the prosecution is not exculpatory merely because appellant so labels it.
Commonwealth v. Gee,
Appellant’s seventh
Brady
claim concerns the Commonwealth’s nondisclosure of a February 18, 1983 statement made by Marie Green, in which she failed to pick out appellant’s picture from a photo array. Green was one of the three barmaids working the night of the robbery. Green was not an identification witness for the Commonwealth, and testified at trial that she did not see the faces of the perpetrators during the robbery. The PCRA court correctly concluded that, at trial, Green’s prior inability to identify appellant from a photo array would not have been admissible. As we have noted, inadmissible evidence cannot be the basis for a
Brady
violation.
See Mitchell,
In addition to his substantive claims, appellant also argues that he is entitled to relief because of the cumulative impact of each Brady violation raised in the instant PCRA petition along with the single Brady claim he raised in his first PCRA petition. (In his first PCRA petition, appellant claimed that the Commonwealth violated Brady by misrepresenting the terms and conditions of the plea bargain extended to Jackson for his testimony.) Appellant’s claim fails. The cumulative impact of meritless Brady claims cannot be grounds for *477 relief. Additionally, appellant’s attempt to re-raise the Brady claim contained in his first PCRA petition is fruitless as it was previously litigated. See 42 Pa.C.S. § 9544(a)(3) (a claim is previously litigated if “it has been raised and decided in a proceeding collaterally attacking the conviction or sentence”).
Appellant also raises one procedural claim on appeal. Appellant asserts that the PCRA court erred by not ruling on his request for discovery which sought a copy of the District Attorney’s entire file, memoranda, or documents in the Commonwealth’s possession that refer to any of the documents appellant characterized as Brady material in the instant PCRA petition, and information on the current whereabouts of any police officers mentioned in the alleged Brady material. Appellant contends that the revelation of the evidence found in the archived police file establishes the necessary “good cause” for discovery under Pa.R.Crim.P. 902(E). Appellant’s claim is meritless as he misapprehends the requisite showing required to obtain discovery for a second PCRA petition.
Rule 902(E), entitled “Requests for Discovery,” provides in full:
(1) Except as provided in paragraph (E)(2), no discovery shall be permitted at any stage of the proceedings, except upon leave of court after a showing of exceptional circumstances.
(2) On the first counseled petition in a death penalty case, no discovery shall be permitted at any stage of the proceedings, except upon leave of court after a showing of good cause.
Pa.R.Crim.P. 902(E). Paragraph two is inapplicable because the instant petition is appellant’s second counseled petition. Therefore, appellant was required to satisfy paragraph one’s standard of “exceptional circumstances” in order to be granted discovery by the PCRA court. Since appellant does not even allege that he demonstrated this required showing, his claim that the PCRA court erred by not granting his discovery request is unfounded.
*478 Accordingly, we conclude that appellant’s claims in his serial PCRA petition are either time-barred or lack merit. We therefore affirm the order of the PCRA court dismissing appellant’s serial petition.
Notes
. The facts underlying appellant’s conviction are set forth in detail in this Court’s opinion on direct appeal.
Commonwealth v. Lambert, 529
Pa. 320,
. In Lark, this Court established the following procedural rule governing serial petitions:
[W]hen an appellant's PCRA appeal is pending before a court, a subsequent PCRA petition cannot be filed until the resolution of review of the pending PCRA petition by the highest state court in which review is sought, or upon the expiration of the time for seeking such review. If the subsequent petition is not filed within one year of the date when the judgment became final, then the petitioner must plead and prove that one of the three exceptions to the time bar under 42 Pa.C.S. § 9545(b)(1) applies. The subsequent petition must also be filed within sixty days of the date of the order which finally resolves the previous PCRA petition, because this is the first "date the claim could have been presented." 42 Pa.C.S. § 9545(b)(2).
Lark,
. Two of the nine alleged Brady violations have not been raised or discussed by appellant in his brief on appeal. Therefore, these claims are not before us.
. During the investigation, Jackson offered four separate statements to the police. On October 14, 1982, Jackson identified himself, Reese, and "the dude” as the three participants in the robbery. On October 22, 1982, Jackson identified "the dude” as "Monk,” which was appellant’s nickname. In his third and fourth statements given on January 14, 1983 and February 6, 1983, Jackson identified "Monk” as appellant.
