New Jersey Supreme Court Holds That Diminished Capacity Requires Expert Testimony

Published on: August 25, 2026 | by Stephen J. Natoli

Courts-Ruling-on-Diminished-Capacity-300x300 The New Jersey Supreme Court has answered a question that has lingered in our criminal courts for decades: can a defendant obtain a diminished capacity jury instruction on lay testimony alone? In State v. Mustafa, a unanimous decision issued on August 3, 2026, the Court held that expert testimony is required both for a defendant to invoke the diminished capacity defense and for a trial court to instruct the jury on it. The Court affirmed the Appellate Division and confirmed that an expert is necessary to support an insanity defense. For anyone who handles serious violent crime cases, this opinion changes how mental health evidence must be developed, and it changes it well before trial begins.

The case arose from a late night shooting on a Monmouth County highway in May 2018. The defendant was driving with his then girlfriend when the victim, traveling on the same roadway, turned on her high beams because one of her headlights was out. The defendant became upset, pulled over to let her pass, then accelerated until he nearly struck her bumper while flashing his own high beams. As her car began to exit, he put his vehicle in neutral, rolled down his window, drew a handgun, and fired. She died of a gunshot wound to the head. A grand jury returned a six count indictment charging first degree murder, weapons offenses, and endangering. Defense counsel initially served notice of an insanity defense, but the defendant later instructed his attorney to withdraw it, and a pretrial memorandum recorded that decision in plain terms, noting that the insanity defense was withdrawn and that there would be no psychiatric expert testimony. The trial court found the waiver knowing and voluntary.

Diminished capacity, however, was raised explicitly at trial, and a fair amount of lay evidence about the defendant’s mental health reached the jury. His then girlfriend testified that he had begun seeing her psychiatrist to obtain Adderall because he liked how it made him feel, that he smoked marijuana daily, and that he had immersed himself in conspiracy research. She described his belief that he was the target of gang stalking, that people were shooting laser beams, radiation, and concentrated microwaves at him, and that he wore tin foil under a baseball cap and helmet to deflect the rays. She said his statements reminded her of a relative who has schizophrenia. On the night of the shooting, she testified, he took Adderall three times within several hours, yelled about people trying to hit him with radiation and follow him, and screamed that he could not take it anymore and had to fight back. The defendant did not testify and called no witnesses. When counsel requested a diminished capacity charge at the close of evidence, arguing that a medical diagnosis was not required, the trial court denied it because there was no medical or expert testimony in the record. The jury convicted on all counts and the defendant received an aggregate life sentence.

Third-Party Payment of Legal Fees Does Not Create a Per Se Conflict: New Jersey Supreme Court Decides State v. Kearney

Published on: August 4, 2026 | by Stephen J. Natoli

Legal-Fees-Paymenr-300x300 The New Jersey Supreme Court issued a unanimous decision in State v. Kearney addressing a question criminal defense attorneys encounter often but rarely litigate: what happens when someone other than the defendant pays the legal bill, and that person later testifies for the State. The Supreme Court held that a third party’s payment of a defendant’s legal fees does not create a per se conflict of interest, and that on this record the defendant failed to establish an actual conflict either. The Court affirmed the denial of post-conviction relief without an evidentiary hearing, and it used the opinion to recommend best practices for documenting third-party fee arrangements going forward.

The case arose from a fatal stabbing in Middlesex County in August 2013. The defendant was at the home of his girlfriend, with whom he shared a child, when a fight broke out among the men in the house. The victim was her cousin. She later told police that after the two of them left together, the defendant said something was wrong with the victim and that he had “poked” him. They returned to find the victim on the floor, and first responders later found him without a pulse. A jury convicted the defendant of first-degree murder and related offenses, and he received an aggregate fifty-year term subject to the No Early Release Act. The conflict issue arose because the girlfriend had hired the defendant’s trial attorney and paid his fees. She testified that she met with him three times, the last in 2014, and that their conversations concerned payment only. At trial the State called her as its witness and emphasized her second statement to police. Defense counsel’s cross-examination focused instead on her earlier account that the victim had been cut, and drew out that she had been held at the station for roughly sixteen hours, had not been allowed to use a bathroom, and had, in her words, been broken by the experience. Counsel also established that she had not visited his office since 2014, had no contact with him beyond paying the fees, and had retained her own unaffiliated lawyer to prepare for her testimony. After an unsuccessful direct appeal, the defendant filed a petition for post-conviction relief asserting that the fee arrangement created a conflict. The PCR court denied it without a hearing, and the Appellate Division affirmed at 479 N.J. Super. 539.

The Court’s analysis began with the duty of loyalty codified in RPC 1.7 and the two-tier framework from State v. Norman. Courts first ask whether the alleged conflict is a per se conflict, meaning one so inherently fraught with divided loyalties that prejudice is presumed and reversal follows unless the defendant knowingly and intelligently waived it on the record. That category is deliberately narrow, covering situations such as simultaneous representation of codefendants and, under State v. Cottle, an attorney under indictment in the same county and prosecuted by the same office as his client. If no per se conflict exists, courts ask whether there was an actual conflict and, if so, whether a great likelihood of prejudice resulted. That inquiry is flexible and fact-sensitive, asking whether the lawyer’s representation was materially limited by responsibilities to another client, a third party, or the lawyer’s own interests. The asserted conflict must rest on more than a fanciful possibility, and a bald assertion will not do. The Court also reaffirmed that waiver is never to be inferred from a silent record.

New Jersey Supreme Court Tightens the “Reasonable Diligence” Standard for New Trial Motions: State v. Nirav Patel

Published on: June 9, 2026 | by Stephen J. Natoli

New-Evidence-300x300 The New Jersey Supreme Court issued a unanimous decision in State v. Nirav Patel that delivers an important message to defendants and defense counsel about newly discovered evidence. The Court held that a defendant who possessed exculpatory documents before trial, knew or had reason to know they existed, and yet never searched for them during the four years between indictment and trial cannot satisfy the reasonable diligence requirement for a new trial. The Court reversed both the trial court and the Appellate Division, which had granted the defendant a new trial, and remanded the matter for sentencing. The decision clarifies how the reasonable diligence prong of the newly discovered evidence standard operates and how much deference appellate courts owe to a trial court’s findings on that question.

The underlying prosecution arose out of a failed restaurant venture in Hoboken. In May 2019, a State grand jury indicted Nirav Patel for second-degree theft by deception. The State alleged that he obtained $750,000 from a group of six investors who believed they were purchasing a 30 percent interest in a planned World of Beer franchise, when in reality Patel owned only a 5 percent interest in the entity that held the franchise rights. The investors’ money was deposited into an account belonging to his family’s business, Bhagu, Inc. A financial crimes investigator testified at trial that the funds were used to pay Patel’s personal expenses, including mortgage and car payments for a residence and a Porsche, to cover debts of the family’s restaurant, and to fund checks made payable directly to Patel. According to the investigator, none of the money ever reached the franchise entity or was used for the benefit of the Hoboken project. In April 2023, nearly four years after the indictment, a jury found Patel guilty.

Eight days after the verdict, Patel moved for a new trial based on newly discovered evidence. At an evidentiary hearing, his sister testified that the family was shocked by the verdict and that she began combing through boxes of documents at their parents’ home, where Patel had lived full-time since 2019. After days of searching, she found eleven pages in the garage referencing Bhagu and World of Beer. Patel then searched his own email accounts using basic terms such as “World of Beer” and “Bhagu,” and within roughly an hour he located complete versions of the documents. Among them were two franchise agreements naming Bhagu, Inc. as the sole franchisee for the Hoboken location and a guaranty reflecting that Patel held a 30 percent interest in an entity called Tapmasters II. Patel argued the documents proved he had authority to sell shares to the investors. World of Beer’s chief development officer testified that he believed the Bhagu agreements were not legitimate and that a search of the company’s records turned up no trace of them. The trial court nonetheless granted a new trial, reasoning that because Patel was involved in many businesses, the evidence was buried among presumably thousands of documents and was not discoverable by reasonable diligence. The Appellate Division affirmed.

New Jersey Supreme Court Rules That Cell Site Location Evidence Requires an Expert Witness

Published on: April 24, 2026 | by Stephen J. Natoli

Cell-Phone-Tower-Expert-300x300 On April 16, 2026, the New Jersey Supreme Court issued a unanimous decision in State v. Jule Hannah that carries significant consequences for how cell phone location evidence can be presented in criminal trials. The Court held that cell site location information, commonly known as CSLI, involves technical and specialized knowledge that is beyond the understanding of the average juror, and therefore must be introduced through a qualified expert witness. The decision affirms the Appellate Division’s reversal of Hannah’s first-degree murder conviction and orders a new trial, drawing a clear line that prosecutors and defense attorneys across New Jersey must now respect.

The case arose from the January 2017 death of Miguel Lopez, who was found shot to death in his car in Bridgeton after crashing into a tree. Investigators developed Hannah as a suspect based on surveillance footage, DNA from a cigar butt recovered from the passenger seat, and cell phone records. At trial, the State sought to use those records to place Hannah in Lopez’s car during the ride from Monroe Township to Bridgeton. Rather than calling a qualified expert, the State presented Detective Sergeant Leyman as a lay witness to testify about which cell towers Hannah’s phone connected to during the relevant time period. The trial court tried to thread the needle allowing Leyman to testify about tower locations while repeatedly instructing the jury that a cell phone’s connection to a tower does not establish where the phone was at any given moment. That tension, the Supreme Court concluded, was precisely the problem.

The Court’s analysis began with a foundational distinction in the rules of evidence between lay and expert testimony. Under New Jersey law, a lay witness can offer opinions based on common knowledge and observation. When a subject is so technical that the average juror cannot form a valid conclusion without guidance, however, expert testimony is required. CSLI, the Court explained, squarely falls into that category. Whether a phone connects to the nearest tower depends not just on proximity but on a constellation of variables such as tower height, antenna direction, terrain and topography, network load balancing, and the technical characteristics of the phone itself. A jury left to draw inferences from raw call records, without any expert framework to interpret them, risks attributing far more or far less weight to that data than the evidence actually warrants.
