PA Supreme Court: Prosecutorial Misconduct to Call a Witness the Prosecution Knows Will Refuse to Testify

Criminal Defense Lawyer Zak T. Goldstein, Esquire

The Pennsylvania Supreme Court has decided the case of Commonwealth v. Belgrave, No. 31 WAP 2024 (Pa. March 26, 2026), holding that it is prosecutorial misconduct to call a witness to testify before a jury when the prosecution knows in advance that the witness intends to refuse to answer questions. The Court reversed the Superior Court’s decision, vacated the defendant’s judgment of sentence, and remanded for a new trial. The opinion was authored by Justice Wecht and joined by every member of the Court.

The Facts of Commonwealth v. Belgrave

The Court summarized the facts as follows: the charges in this case arose from a drug sale at a Marriott Hotel in Erie, Pennsylvania, on February 7, 2019, that ended in a gunfight. Four men, including the defendant, drove from Chicago to Erie and rented a hotel room. Hotel surveillance video showed that Belgrave and his associate, Charles Baizar, were parked in a Chevrolet Impala when a dark-colored SUV arrived in the parking lot. Baizar and another man walked toward the SUV, and when Baizar attempted to enter it, the SUV’s driver exited the vehicle and began shooting. Baizar ran, dropping a package. Belgrave exited the Impala and fired two shots in the direction of the SUV. Belgrave was shot and seriously injured.

Police stopped the Impala as it was leaving a nearby parking garage. The package that Baizar dropped during the gunfight contained 239 grams of heroin. Baizar was separately charged with conspiracy to commit PWID and pleaded guilty to conspiracy in December 2019. Belgrave was charged with conspiracy to commit PWID (amended on the eve of trial to PWID), aggravated assault, and other offenses. A jury convicted Belgrave of PWID, reckless endangerment, and carrying a firearm without a license.

The Prosecutorial Misconduct Issue

The central issue in this appeal was the prosecution’s decision to call Baizar to the witness stand at Belgrave’s trial despite knowing in advance that Baizar would refuse to answer any questions. Belgrave’s defense counsel identified this problem early, filing a motion in limine on the eve of trial. The concern was well-founded: Baizar had filed his own Motion to Quash Subpoena the day before Belgrave’s trial began, stating clearly that he had no intention of testifying and intended to invoke his Fifth Amendment right against self-incrimination.

The Commonwealth sought to compel Baizar’s testimony by offering him immunity. But even with immunity, which eliminated any valid Fifth Amendment basis for refusing to testify, Baizar still refused to testify and was subject to contempt sanctions. Despite all of this, the prosecutor went ahead and called Baizar to the stand in front of the jury.

What followed was remarkable. In his opening statement, the prosecutor told the jury to look forward to Baizar’s testimony while simultaneously revealing that Baizar did not want to cooperate. When Baizar took the stand, he refused to answer every substantive question. But the prosecutor pressed on, asking eighteen predominantly leading questions that were loaded with accusations. The prosecutor asserted that Baizar was Belgrave’s cousin, that they came to Erie to sell heroin together, that Baizar had made prior statements to police about the incident, and that Baizar was refusing to testify because he wanted to protect Belgrave. Baizar answered none of the questions. The prosecutor essentially became the de facto testifying witness, putting allegations before the jury in the form of unanswered questions.

The trial court gave a limiting instruction telling the jury that questions are not evidence and that only answers may be considered. But the Supreme Court found this wholly insufficient to cure the prejudice. In closing arguments, the prosecutor doubled down, telling the jury that Baizar knew what happened, knew who was involved, and refused to say anything. He implored the jury to infer facts from an interaction that consisted entirely of unanswered questions.

The Supreme Court’s Analysis

The Supreme Court engaged in a thorough review of its prior case law governing this issue, beginning with the 1973 cases of Commonwealth v. Terenda, 301 A.2d 625 (Pa. 1973), and Commonwealth v. DuVal, 307 A.2d 229 (Pa. 1973). In Terenda, the Court found it was prejudicial error for the prosecution to call co-indictees to the stand knowing they would invoke the Fifth Amendment. In DuVal, the Court held that summoning a witness with foreknowledge that the witness would invoke the privilege against self-incrimination constitutes prejudicial error in itself, regardless of whether the prosecutor believed the privilege claim would be legally invalid. The DuVal Court explained that the proper procedure is for the prosecution to test the witness’s willingness to testify in advance, outside the jury’s presence, and obtain a ruling before bringing the witness before the jury.

The Superior Court had distinguished Terenda and DuVal on a narrow basis: in those cases, the witnesses expressly invoked the Fifth Amendment in front of the jury, while Baizar simply refused to answer without specifically mentioning the Fifth Amendment. The Superior Court relied on the separate case of Commonwealth v. Todaro, 569 A.2d 333 (Pa. 1990), where this Court found no error when a witness quietly informed the court of his intent to invoke the Fifth Amendment, was excused before the jury, and never appeared again.

The Supreme Court found the analogy to Todaro deeply flawed. In Todaro, the prosecutor did not have advance notice that the witness would refuse to testify, the witness was quickly excused, and no accusatory questions were asked before the jury. In Belgrave, by contrast, everyone knew Baizar would not answer, the prosecutor called him anyway, and then peppered him with leading, accusatory questions designed to plant inculpatory information in the jurors’ minds through the questions themselves.

The Court also rejected the Superior Court’s reasoning that the absence of an express Fifth Amendment invocation before the jury somehow made Baizar’s defiant silence less prejudicial. The Court found that this distinction defied common sense, observing that the prejudicial harm lies in the refusal to deny accusations, which a reasonable juror can treat as an implied admission, and that this harm exists regardless of whether the witness cites a specific legal basis for the refusal.

The Court further held that the error was not harmless beyond a reasonable doubt. The prosecution’s extensive efforts to obtain Baizar’s testimony, including securing immunity directly from the District Attorney, demonstrated how critical the prosecution considered Baizar’s testimony to be. The prosecutor’s repeated emphasis on Baizar’s knowledge and silence, in both opening and closing statements, confirmed this.

The Takeaway

Commonwealth v. Belgrave is a significant decision for criminal defendants in Pennsylvania. It reaffirms and strengthens the rule from DuVal that prosecutors may not call witnesses they know will refuse to answer questions before a jury. The Court made clear that it is the act of summoning the witness, not what happens after the witness takes the stand, that constitutes the misconduct. And it rejected the artificial distinction between an express invocation of the Fifth Amendment and a simple refusal to answer, holding that the prejudice to the defendant is the same either way.

The decision also underscores the obligation of trial courts to resolve these issues before a witness ever appears in front of the jury. As the Court emphasized, citing DuVal and Commonwealth v. Davenport, 308 A.2d 85 (Pa. 1973), the proper procedure is a pre-appearance hearing to assess the witness’s willingness to testify and determine whether the witness’s appearance before the jury would serve any legitimate purpose.

This is a unanimous decision, with all seven justices joining Justice Wecht’s opinion, which gives it particular force as precedent. If you or someone you know is facing criminal charges and believes that the prosecution engaged in misconduct at trial, it is critical to consult with an experienced criminal defense attorney who can evaluate whether the issue warrants appellate relief or a new trial.

PA Supreme Court: Trial Court May Not Consolidate Separate Sexual Assault Cases Based Solely on “Similar” Allegations, and Rape Kits Are Testimonial Under the Confrontation Clause

Criminal Defense Lawyer Zak T. Goldstein, Esquire

The Pennsylvania Supreme Court has decided the case of Commonwealth v. Walker, holding that the trial court abused its discretion when it consolidated three separately-charged CODIS hit rape cases for a joint trial under the common plan, scheme, or design exception to the rule against propensity evidence.

The Court also held that the admission of rape kit reports without testimony from the nurse examiners who actually prepared them violated the defendant's constitutional right to confrontation. This is a landmark decision that significantly tightens the standard for when the prosecution may try separate offenses together and provides important new protections for defendants in sexual assault cases.

The Facts of Commonwealth v. Walker

In July of 2019, the defendant was arrested and charged with the rape of three different women on three separate occasions — P.C. in January of 2011, T.A. in December of 2014, and B.H. in January of 2015. Each complainant underwent a sexual assault examination after the attack, and DNA from the perpetrator was recovered and uploaded to the Combined DNA Index System (CODIS). In December of 2018, a CODIS search revealed that the male DNA samples from all three victims matched, and that DNA profile was later linked to Walker.

In each case, the defendant met the victim, a stranger, on a public street in Philadelphia, convinced her to follow him to a secluded area, and then sexually assaulted her. However, the specific details of each assault varied significantly. In one case, the perpetrator used a knife; in another, he punched the victim in the face; in the third, he struck the victim with a tire iron. He robbed only one of the three victims. One rape occurred near midnight while the other two occurred during the late morning. Each assault took place in a different Philadelphia neighborhood.

The Commonwealth moved to consolidate all three cases for a joint trial, arguing that the evidence of each assault would be admissible at a trial for the others because the assaults shared sufficient similarities to establish a common plan, scheme, or design. Despite the defendant’s objection, the trial court granted the Commonwealth's motion.

Prior to trial, the defendant also filed a motion in limine seeking to preclude the Commonwealth from introducing the rape kit reports prepared by the sexual assault nurse examiners at the Philadelphia Sexual Assault Response Center (PSARC) for two of the three victims. The Commonwealth acknowledged that the nurses who actually performed the examinations no longer worked at PSARC. Instead, the prosecution planned to introduce the reports through the testimony of PSARC's nurse manager and clinical director who did not personally conduct any of the examinations. The trial court denied the defendnat’s motion.

At trial, the defendant was convicted on numerous charges including rape, involuntary deviate sexual intercourse, and sexual assault. He was sentenced to an aggregate of 28 to 56 years' imprisonment and classified as a Tier III sex offender with lifetime registration under SORNA. The Superior Court affirmed, and the Supreme Court granted allowance of appeal.

The Supreme Court's Ruling on Consolidation

The Pennsylvania Supreme Court reversed, finding that the trial court abused its discretion in consolidating the three cases. Under Pennsylvania Rule of Criminal Procedure 582, separate offenses may be tried together only if the evidence of each offense would be admissible in a separate trial for the other. The key question was therefore whether evidence of the other rapes would have been admissible under the common plan, scheme, or design exception to Pennsylvania Rule of Evidence 404(b), which generally bars the prosecution from introducing evidence of a defendant's other bad acts to show criminal propensity.

Critically, the Court took the opportunity to reshape the law on this issue. Over the years, Pennsylvania courts had applied an increasingly diluted version of the common plan, scheme, or design exception. What started as a narrow exception, requiring either a true overarching plan linking crimes together or a modus operandi so distinctive as to be a signature, had devolved into a vague “logical connection” test that merely required “sufficient similarities” between the crimes. The Court recognized that this relaxed standard effectively gutted Rule 404(b)’s core protection against propensity evidence.

Writing for the majority, Justice McCaffery abrogated the “logical connection” test and returned to the original two-pronged framework from Shaffner v. Commonwealth, 72 Pa. 60 (1872). Going forward, the Commonwealth may consolidate separately-charged offenses under the common plan, scheme, or design exception only where it can establish either: (1) the offenses constitute “signature crimes,” meaning the facts are so unique and distinctive that they must have been committed by the same perpetrator; or (2) the offenses were linked to achieve a common goal, meaning the bad acts are part of an integrated plan to accomplish a specific objective.

Applying this newly clarified standard to the defendant’s case, the Court found that neither exception was satisfied. First, the three rapes did not qualify as signature crimes. While all three involved stranger assaults, the specific details varied considerably. The perpetrator used different weapons (or none at all), initiated contact differently, and committed the assaults in different neighborhoods at different times. These were, as the Court put it, characteristics typical of any stranger rape case, not a unique signature. Second, there was no evidence of a preconceived plan linking the three crimes together to achieve a common goal. The evidence simply showed that the perpetrator raped women when presented with the opportunity to do so. A general desire to commit the same type of crime is not the kind of common plan or scheme that Rule 404(b) contemplates.

The Court also emphasized an important procedural point. The decision to consolidate cases is made pretrial, before the defendant has revealed any defense strategy. The Commonwealth cannot justify consolidation based on its anticipatory rebuttal of a defense, such as a consent defense, that the defendant has not yet raised. A defendant has no duty to present evidence and may instead rely on the presumption of innocence and the Commonwealth's burden of proof.

The Supreme Court's Ruling on the Rape Kit Reports

The Supreme Court also ruled in the defendant’s favor on the Confrontation Clause issue. The Sixth Amendment and Article I, Section 9 of the Pennsylvania Constitution guarantee criminal defendants the right to confront the witnesses against them. In a line of cases including Crawford v. Washington, Melendez-Diaz v. Massachusetts, Bullcoming v. New Mexico, and most recently Smith v. Arizona, the United States Supreme Court has made clear that the Confrontation Clause applies to forensic reports and that the prosecution may not introduce testimonial hearsay, including forensic reports, without providing the defendant an opportunity to cross-examine the person who actually prepared the report.

The Pennsylvania Supreme Court held that rape kit reports are testimonial in nature. The reports are formally titled “Sexual Assault Forensic Examination Forms,” and the very word “forensic” signals their evidentiary purpose. The reports were created primarily to establish past events and collect evidence relevant to a potential criminal prosecution, not simply to provide medical treatment. The Court also noted that Pennsylvania statute explicitly defines a rape kit as a “sexual assault evidence collection kit,” and the law requires health care facilities to notify law enforcement of the alleged assault.

Because the rape kit reports were testimonial and were offered for their truth at trial, the Confrontation Clause required the testimony of the nurse examiners who actually prepared them. The testimony of PSARC’s clinical director, who did not personally perform any of the examinations, was not an adequate substitute. The Court rejected the Commonwealth's argument that the reports were admissible under the medical records or business records exceptions to the hearsay rule. Hearsay exceptions cannot override the Confrontation Clause. When an out-of-court statement constitutes testimonial hearsay, it may not be admitted at trial unless the defendant had the opportunity to cross-examine the declarant, regardless of whether the statement would otherwise qualify as a hearsay exception.

The Takeaway

Commonwealth v. Walker is one of the most significant Pennsylvania Supreme Court decisions in recent years for criminal defendants. On the consolidation issue, the Court meaningfully strengthened the protections of Rule 404(b) by rejecting the watered-down “logical connection” test and demanding that the Commonwealth meet a real standard before it can try separate cases together. This matters because consolidation is enormously prejudicial. A jury hearing about multiple allegations is far more likely to convict on all of them than a jury considering each charge independently. Going forward, the prosecution will need to show either a true signature crime or a genuine common plan linking the offenses together, rather than simply pointing to broad similarities between different cases.

On the Confrontation Clause issue, the decision provides a clear rule for sexual assault cases: the prosecution must produce the actual nurse examiner who prepared the rape kit report, or it cannot introduce the report. This prevents the Commonwealth from relying on a “surrogate witness” who simply reads the absent nurse’s report into the record.

Defense attorneys handling sexual assault cases, cases involving motions to consolidate, or cases involving the admission of forensic reports should take note of this decision and use it to protect their clients’ rights.

PA Supreme Court Fails to Reach Decision on Whether Search Warrant Required for Google’s Search Records

Criminal Lawyer Zak Goldstein

On December 16, 2025, the Pennsylvania Supreme Court issued a fractured decision in Commonwealth v. Kurtz, addressing a cutting-edge digital privacy question: do you have a reasonable expectation of privacy in the terms you type into a Google search bar?

The Court’s answer was “no”—at least for general, unprotected searches. However, because the decision was reached by a plurality (meaning a majority of justices did not agree on a single legal reasoning), it is not binding, and the ruling leaves significant questions unanswered regarding other types of digital data, particularly Internet Service Provider (ISP) records and IP address subscriber information.

Commonwealth v. Kurtz: The “Reverse Keyword” Warrant

In Kurtz, police were investigating a violent home invasion rape but had no DNA match or suspect. Investigators obtained a “reverse keyword search warrant” compelling Google to identify any IP addresses that had searched for the victim’s home address prior to the crime. Google identified an IP address associated with the defendant, leading to additional investigation, an eventual DNA match, and his conviction for rape in this case and other unsolved cases.

The defendant challenged the warrant, arguing he had a privacy interest in his search history and that the warrant provided no reason to believe that the perpetrator conducted a Google search at all let alone for the victim’s address. The trial court rejected this claim, and the defendant appealed. The Superior Court rejected the claim, too, finding that the defendant did not have a reasonable expectation of privacy in the records maintained by Google and that the police had obtained a legitimate search warrant even if he did. The defendant petitioned the Supreme Court for review, and the Pennsylvania Supreme Court agreed to hear the case. That Court, however, failed to reach a decision - three justices concluded that he had no reasonable expectation of privacy in the search records, three concluded that the warrant was fine and declined to address the REOP decision, and one justice would have granted the motion to suppress.

Accordingly, the Court affirmed the defendant’s conviction as it would have required four justices to vote to overturn it. In support of upholding the conviction, Justice Wecht authored an Opinion Announcing the Judgment of the Court (OAJC) which reasoned that the defendant did not have a reasonable expectation of privacy in the information and that investigators did not have to obtain a warrant at all because:

• Voluntary Disclosure: By typing a query into Google, the user voluntarily discloses that information to a third party, meaning the user does not make an attempt to keep the information private.

• Notice: Google’s privacy policy explicitly warns users that it collects search queries and shares them with law enforcement.

• Lack of Necessity: The Court noted that using Google is a choice, not a necessity; users can use other search engines, libraries, or physical maps. They can also take steps to shield their identities and increase their privacy.

Accordingly, the defendant had no reasonable expectation of privacy in the search results.

Why Kurtz Is Not the Final Word

While Kurtz is a significant ruling for search history and the Superior Court’s ruling stands, it is not a total defeat for digital privacy rights in Pennsylvania for two key reasons:

1. It Is a Plurality Opinion: Crucially, the main opinion in Kurtz was joined by only three of the seven justices. When a court decides a case without a majority opinion, the holding is generally limited to the specific result of that case, and the legal reasoning is not fully binding precedent for future cases. This means the broad language about the third-party doctrine may not apply automatically to different factual scenarios or even similar scenarios.

2. It Is Limited to "Unprotected" Searches: The Court repeatedly stressed that its ruling applied only to “general, unprotected internet searches.” The justices expressly stated they were not deciding the privacy rights of users who utilize Virtual Private Networks (VPNs), private browsing modes, or encrypted browsers. Moreover, the courts have required legitimate search warrants where investigators seek to obtain bank records, phone records, and location data.

The Next Battleground: IP Addresses and ISP Records

The Kurtz decision creates a sharp distinction that defense attorneys can use in cases involving IP addresses and ISP subscriber records (the information “behind” the IP address, such as the customer's name and address).

In Kurtz, the Court emphasized that users have a choice: they can use Google, or they can use a privacy-focused competitor (like DuckDuckGo) or offline resources . However, this logic does not apply to IP addresses. Kurtz dealt with whether the police could obtain a list of IP addresses that had searched for a particular address. It did not address whether the police could obtain the information behind the resulting IP addresses without a search warrant, and in Pennsylvania, police often use administrative subpoenas to obtain that information rather than warrants. Whether they can do that under the Pennsylvania Constitution remains questionable for the following reasons:

• Necessity vs. Convenience: You cannot use the internet without an IP address. It is technologically impossible. Unlike choosing a search engine, assigning an IP address is an involuntary condition of internet access, similar to how bank records or phone numbers are necessary to participate in modern life. Pennsylvania courts have long held that citizens do have privacy rights in bank records (Commonwealth v. DeJohn) and phone records (Commonwealth v. Melilli) because they are essential services.

• The “Information Behind the IP”: Kurtz dealt with the content of a search communicated to Google. ISP inquiries deal with the identity of the user maintained by the internet provider. This information is generated automatically by the ISP, not voluntarily typed out by the user.

The Takeaway

At least for now, Commonwealth v. Kurtz establishes that if you type a search into Google without privacy protections, you cannot expect that search to remain private from police. However, because the decision relies heavily on the “voluntary” nature of using Google and Google’s explicit privacy warnings, it may not extend to the mandatory, automatic records generated by simply connecting to the internet via an ISP.

If you are facing charges based on digital evidence, IP address identification, or administrative subpoenas, the specific technical details of your case matter. The law is evolving rapidly, and a nuanced defense strategy is essential.

PA Supreme Court: Expert Testimony on “Manner of Death” Must Be Held to a Reasonable Degree of Medical Certainty

Criminal Defense Lawyer Zak T. Goldstein, Esquire

The Pennsylvania Supreme Court has issued a significant decision in Commonwealth v. Fitzpatrick, ruling that expert witnesses testifying about the "manner of death" in a homicide case must hold their opinions to a "reasonable degree of medical certainty." The Court rejected the Commonwealth’s argument that a lower standard—mere probability—should apply when an expert offers an opinion on whether a death was a homicide or an accident.

This ruling is a critical victory for defendants because it prevents the prosecution from using expert witnesses who are merely guessing or who cannot stand behind their conclusions with the requisite level of professional certainty.

The Facts of the Case

The case arose from a tragic incident in 2012. On June 6, 2012, Annemarie Fitzpatrick drowned in Muddy Creek, a tributary of the Susquehanna River. Her husband, Joseph Fitzpatrick, claimed that they were riding an ATV when the vehicle flipped backwards, throwing them both into the water. He claimed he could not save her.

Police investigations later uncovered suspicious circumstances, including a note in Annemarie’s day planner reading "If something happens to me—JOE," an extramarital affair, and significant life insurance policies. Joseph Fitzpatrick was eventually charged with and convicted of first-degree murder. However, that conviction was overturned because the trial court had improperly admitted the victim's note as evidence.

As the Commonwealth prepared for a retrial, they sought to introduce a new expert witness, Dr. James Caruso. Dr. Caruso, a forensic pathologist, was set to testify that the "manner of death" was homicide rather than an accident. However, during a pre-trial hearing, Dr. Caruso admitted that he did not hold this opinion to a "reasonable degree of medical certainty." Instead, he testified that he believed it was "more likely than not" a homicide.

The trial court ruled that Dr. Caruso’s testimony was inadmissible because it failed to meet the legal standard for expert testimony. The Commonwealth appealed, and the Superior Court reversed the trial court, creating a new rule that "manner of death" opinions need only be "probable" or "sturdy" rather than reasonably certain. The defense appealed to the Pennsylvania Supreme Court.

The Legal Issue

The issue before the Supreme Court was whether expert testimony regarding the manner of death (e.g., homicide, suicide, accident) is subject to the same strict evidentiary standards as testimony regarding the cause of death (e.g., drowning, gunshot wound).

The Commonwealth argued that because a jury can determine the manner of death without expert assistance, an expert who does testify on the subject should not be held to the strict "reasonable degree of medical certainty" standard. They argued that a "more likely than not" standard was sufficient.

The Supreme Court's Decision

In a definitive opinion written by Justice Wecht, the Pennsylvania Supreme Court reversed the Superior Court and reinstated the trial court’s order excluding the expert testimony.

The Court held that all expert testimony, regardless of the topic, must be held to a reasonable degree of professional certainty. The Court explained that experts enjoy a privileged place in the courtroom and are permitted to offer opinions on ultimate issues that lay witnesses cannot. Because of this power, their opinions must be "based on a reasonable degree of medical certainty rather than upon mere speculation".

The Court explicitly rejected the Superior Court's attempt to lower the bar for manner of death testimony. The Court noted that allowing an expert to testify that a homicide was “more likely than not” (a 51% probability) would violate long-standing evidentiary rules, specifically citing the precedent in Griffin, where a 51/49 probability was deemed inadmissible.

Because Dr. Caruso admitted he could not state his opinion to a reasonable degree of medical certainty, his testimony was mere speculation in the eyes of the law and therefore inadmissible.

Key Takeaway

This case reinforces a fundamental protection for criminal defendants in Pennsylvania. The prosecution cannot bolster its case with expert witnesses who are unsure of their conclusions. If an expert is going to tell a jury that a death was a homicide, they must be able to say so with professional certainty, not just as a probability or a guess.

This decision also highlights the importance of rigorous pre-trial litigation. By challenging the expert's qualifications and the certainty of his opinion before the trial began, the defense prevented damaging, unreliable testimony from ever reaching the jury. It is always much harder to undo a wrongful conviction after the fact as appellate courts are often reluctant to overturn jury verdicts and may find harmless error. Additionally, appeals can take years, so even a successful appeal may mean the defendant has spent years in prison during the litigation before winning.
