An psychologist can base his testimony off his own unsworn report – are you really surprised?

By Jason Tenenbaum 8 min read

Key Takeaway

Expert psychologist testimony based on unsworn peer review reports is admissible when witness can explain factual basis and be cross-examined in no-fault insurance cases.

Attorney Jason Tenenbaum brings 24+ years of hands-on experience to this analysis, drawing from his work on more than 1,000 appeals, over 100,000 no-fault cases, and recovery of over $100 million for clients throughout Nassau County, Suffolk County, Queens, Brooklyn, Manhattan, and the Bronx.

Expert Testimony and Peer Review Reports in No-fault Insurance Cases

In no-fault insurance litigation, the admissibility of expert testimony often becomes a contentious issue, particularly when insurance companies rely on peer review reports to deny claims. The case of Psychology YM, P.C. v Geico Gen. Ins. Co. illustrates a fundamental principle about expert witness testimony and the foundation required for admitting professional opinions in court.

The lower court’s decision to exclude the psychologist’s testimony based solely on the format of his peer review report reflects a misunderstanding of evidence rules. When an expert witness is available to testify about the factual basis for their professional opinion and can be subjected to cross-examination, the technical form of their underlying report becomes less significant. This principle applies broadly across various types of expert testimony in personal injury and insurance cases.

Jason Tenenbaum’s Analysis:

Psychology YM, P.C. v Geico Gen. Ins. Co., 2011 NY Slip Op 51316(U)(App. Term 2d Dept. 2011)

Why this objection was even considered is crazy. It does not pass the smell test, let alone the laugh test. Yet, I cannot say I am the least bit surprised. Luckily, the order was reversed. Unfortunately, a new trial was ordered. The complaint should have been dismissed with prejudice.

“At a nonjury trial, the Civil Court granted plaintiff’s motion to preclude the testimony of defendant’s witness, the psychologist who had prepared the peer review report upon which defendant’s claim denial was predicated, because his peer review report was not in admissible form. The Civil Court thereupon awarded judgment in favor of plaintiff in the principal sum of $1,078.48. In view of the fact that defendant sought to call as a witness its psychologist, who was prepared to testify about the factual basis and medical rationale for his opinion, as set forth in his peer review report, that there was a lack of medical necessity for the services rendered, and since he was subject to cross-examination, it was error for the Civil Court to have precluded him from testifying”

Key Takeaway

The appellate court correctly recognized that expert testimony should not be excluded merely because the underlying report lacks proper certification. When an expert can explain their methodology and conclusions under oath and face cross-examination, the foundational requirements for admissibility are satisfied, regardless of the report’s technical format.

Legal Context

Why This Matters for Your Case

New York law is among the most complex and nuanced in the country, with distinct procedural rules, substantive doctrines, and court systems that differ significantly from other jurisdictions. The Civil Practice Law and Rules (CPLR) governs every stage of civil litigation, from service of process through trial and appeal. The Appellate Division, Appellate Term, and Court of Appeals create a rich and ever-evolving body of case law that practitioners must follow.

Attorney Jason Tenenbaum has practiced across these areas for over 24 years, writing more than 1,000 appellate briefs and publishing over 2,353 legal articles that attorneys and clients rely on for guidance. The analysis in this article reflects real courtroom experience — from motion practice in Civil Court and Supreme Court to oral arguments before the Appellate Division — and a deep understanding of how New York courts actually apply the law in practice.

Common Questions

Frequently Asked Questions

What types of evidence are important in no-fault and personal injury cases?

Key types of evidence include medical records and bills, police accident reports, diagnostic imaging (MRI, X-ray, CT scans), expert medical opinions, business records from insurance companies and providers, witness statements, photographs of injuries and the accident scene, and employment records for lost wage claims. The rules of evidence under New York CPLR and the Evidence Rules govern what is admissible in court proceedings.

What is the business records exception to hearsay in New York?

Under CPLR 4518(a), a business record is admissible if it was made in the regular course of business, it was the regular course of business to make such a record, and the record was made at or near the time of the event recorded. This exception is crucial in no-fault litigation because insurers' denial letters, claim logs, and peer review reports are often offered as business records. The foundation for the business record must be established through testimony or a certification.

What role does diagnostic imaging play as evidence in injury cases?

Diagnostic imaging — MRIs, CT scans, X-rays, and EMG/NCV studies — provides objective evidence of injuries such as herniated discs, fractures, ligament tears, and nerve damage. Courts and arbitrators give significant weight to imaging evidence because it is less subjective than physical examination findings. In serious injury threshold cases under §5102(d), imaging evidence corroborating clinical findings strengthens the plaintiff's case considerably.

How do New York courts handle surveillance evidence in personal injury cases?

Insurance companies frequently hire investigators to conduct video surveillance of plaintiffs to challenge injury claims. Under CPLR 3101(i), a party must disclose surveillance materials prior to trial, including films, photographs, and videotapes. Surveillance evidence can be powerful for impeachment if it contradicts the plaintiff's testimony about limitations. However, courts may preclude surveillance that was not properly disclosed or that is misleadingly edited.

How are expert witnesses used in New York personal injury cases?

Expert witnesses provide specialized opinion testimony that helps the court or jury understand complex issues like medical causation, injury severity, future care needs, economic losses, and engineering defects. Under New York law, expert testimony must be based on facts in evidence, the expert's professional knowledge, or a combination of both. The expert must be qualified by training, education, or experience in the relevant field. Expert disclosure requirements under CPLR 3101(d)(1)(i) require parties to identify their experts and provide detailed summaries before trial.

Understanding New York Evidence Law

New York has a unique legal landscape that affects how evidence cases are litigated and resolved. The state's court system includes the Civil Court (for claims up to $25,000), the Supreme Court (the primary trial court for unlimited jurisdiction), the Appellate Term (which hears appeals from lower courts), the Appellate Division (divided into four Departments, with the Second Department covering Long Island, Brooklyn, Queens, Staten Island, and several upstate counties), and the Court of Appeals (the state's highest court). Each court has its own procedural requirements, local rules, and case-assignment practices that can significantly impact the outcome of your case.

For evidence matters on Long Island, cases are typically filed in Nassau County Supreme Court (at the courthouse in Mineola) or Suffolk County Supreme Court (in Riverhead). No-fault arbitrations are heard through the American Arbitration Association, which assigns arbitrators throughout the metropolitan area. Workers' compensation claims go to the Workers' Compensation Board, with hearings at district offices across the state. Understanding which forum is appropriate for your case — and the specific procedural rules that apply — is essential for a successful outcome.

The procedural landscape in New York also includes important timing requirements that can affect your case. Most civil actions are subject to statutes of limitations ranging from one year (for intentional torts and claims against municipalities) to six years (for contract actions). Personal injury cases generally have a three-year deadline under CPLR 214(5), while medical malpractice claims must be filed within two and a half years under CPLR 214-a. No-fault insurance claims have their own regulatory deadlines, including 30-day filing requirements for applications and 45-day deadlines for provider claims. Understanding and complying with these deadlines is critical — missing a filing deadline can permanently bar your claim, regardless of how strong your case may be on the merits.

Attorney Jason Tenenbaum regularly practices in all of these venues. His office at 326 Walt Whitman Road, Suite C, Huntington Station, NY 11746, is centrally located on Long Island, providing convenient access to courts and offices throughout Nassau County, Suffolk County, and New York City. Whether you need representation in a no-fault arbitration, a personal injury trial, an employment discrimination hearing, or an appeal to the Appellate Division, the Law Office of Jason Tenenbaum, P.C. brings $24+ years of real courtroom experience to your case. If you have questions about the legal issues discussed in this article, call (516) 750-0595 for a free, no-obligation consultation.

New York's substantive law also presents distinct challenges. In motor vehicle cases, the no-fault system under Insurance Law Article 51 provides first-party benefits regardless of fault, but limits the right to sue for non-economic damages unless the plaintiff establishes a "serious injury" under one of nine statutory categories. This threshold — codified at Insurance Law Section 5102(d) — requires medical evidence showing more than a minor or subjective injury, and courts have developed detailed standards for each category. Fractures must be documented through imaging studies. Claims of permanent consequential limitation or significant limitation of use require quantified range-of-motion testing with comparison to norms. The 90/180-day category demands proof that the plaintiff was unable to perform substantially all of their usual daily activities for at least 90 of the 180 days following the accident.

In employment discrimination cases, the legal standards vary depending on whether the claim arises under state or local law. The New York State Human Rights Law employs a burden-shifting framework: the plaintiff must first establish a prima facie case by showing membership in a protected class, qualification for the position, an adverse employment action, and circumstances giving rise to an inference of discrimination. The burden then shifts to the employer to articulate a legitimate, non-discriminatory reason for its decision. If the employer meets this burden, the plaintiff must demonstrate that the stated reason is pretextual. The New York City Human Rights Law, by contrast, applies a broader standard, asking whether the plaintiff was treated less well than other employees because of a protected characteristic.
