If you are going to spend money on a rebuttal, make sure (s)he has the proper credentials.  As many people have told me in life, you get what you pay for.  This case, a colossal disaster, proves that point.  In fact, I am hoping Plaintiff appeals this…

Five Boro Psychological Servs. v GEICO Ins. Co., 2011 NY Slip Op 50882(U)(Civ. Ct. Kings Co. 2011)

“Plaintiff then called Vladimir Grinsberg (“Grinsberg”) as a rebuttal witness. Grinsberg was a clinical psychologist in the Ukraine where he worked for six years in a psycho – neurological clinic. He claims that he administered the five tests at issue while working in the Ukraine.

Upon arriving in America, he obtained a masters in social work from Adelphi University; he is not a clinical social worker, which requires a doctorate. Ten years ago, Grinsberg worked as a social worker with the Jewish Board of Family and Children’s Services ( “Jewish Board”) doing family psychotherapy and teaching families. While working at the Jewish Board, Grinsberg administered and implemented treatment plans for private patients. He treated patients from the beginning to the end, which included reviewing tests, writing reports and interpreting the results of the test. He got reimbursed by insurance companies as a private practitioner”

There is no talismanic rule defining whether a witness is an expert or not, as “various combinations of education , training, observation or experience” may suffice, although none of the aforementioned criteria, standing alone, are determinative. Mtr. Of R..M. Children, 165 Misc 2d 441 444 ( Family Ct., Kings Co. 1995). See, Steinbach, supra, 2 AD3d at 710. Thus, the fact that a proffered witnesses does not possess an advanced degree from a university that is nationally accredited does not disqualify him when he possesses a doctoral dissertation on the subject at issue (occultism) and has “more than ordinary knowledge of nontraditional groups and the occult. “ Echols v. State., 326 Ark. 917, 936 S.W. 2d 509 (Sup Ct. Ark. 1996). Similarly, the lack of a medical licenses does not, in and of itself, disqualify a witness from testifying as an expert on a medical question, Steinbach supra (podiatrist, while only licensed to treat below the ankles, established that he had professional experience in diagnosing and treating burns both above and below ankle and hence could offer expert testimony as to the respondent podiatrist’s alleged malpractice in treating the plaintiff’s burn injury on the calf). A witness need not possess a special license within a general licensed area in order to testify Smith v. City of NY, 238 AD2d 500 (2d Dept. 1997)(plaintiff’s doctor, while not a psychiatrist, had experience in the area of hysteria conversion and thus could testify about the subject; fact that he was not a psychiatrist went to the weight, but not admissibility of his testimony). Similarly the fact that a doctor obtained a degree in a foreign country as opposed to the U.S. does not constitute an automatic disqualifier. Meiselman v. Crown Heights Hospital, 285 NY 389 (1941).

Based upon the above, the court finds that Grinsberg does not possess the combination of long observation, real experience or sufficient education or training to be qualified as an expert on psychological testing. While Grinsberg testified that he administered the five tests at issue while working as a clinical psychologist in the Ukraine, he did not elaborate upon his experience with these psychological tests or at what frequency he utilized the tests. Although Grinsberg did not testify how long he has been in the United States, it is clear that he has not worked as a psychologist since coming to the United State which, according to his testimony, is at least 10 years . He did not indicate that his studies to earn a masters in social work gave him sufficient experience or familiarity with the psychological tests at issue. During these ten years, he has neither administered these tests nor conducted the diagnostic interviews which Dr. Porter testified are essential in order to ascertain the mental status of a given patient.

Off greater import, since commencing his work with All – Boro some six years ago, Grinsberg has not even worked in the capacity of a social worker but rather administered the day – day administrative aspects of the All – Boro. Furthermore, he blithely dismissed any differences between a psychologist or social worker in New York State although he admitted that he is not [*5]aware of what is required for to be a licensed psychologist in this state.

In fact, there are substantial differences in the licensure requirements and practice of a psychologist as compared to a social worker in this State. Compare Education Law §7601-a (definition of scope of practice of psychology) with Education Law §7701(1) (definition of scope of practice of licensed master social work) and Education Law §7701(2) (definition of scope of licensed clinical social work). See generally, People of State of NY v, RR, 12 Misc 3d 161 (Sup. Ct. NY Co. 2005).

Of even greater significance to the instant matter is the difference in scope of practice between a licensed master social worker and a licensed clinical social worker. Prior to 2002, New York State only protected the use of the titles of psychologist and certified social worker, which meant that anyone could legally practice psychology or social work so long as they did not hold themselves out as social workers or psychologists or describe their services as being psychological in nature. People of State of NY supra, 12 Misc 3d at 168. In 2002, the Legislature enacted news laws licensing the practice of psychology and social work and, in particular distinguished between licensed master social workers and clinical social workers. (Laws, 2002, Ch. 420, §1, eff. 9/1/04).

The social work statute contains “two tiers of social work so that the scope of practice of a licensed master social is included within the larger scope of practice of licensed clinical social work_. People of State of NY, supra,_ 12 Misc 3d at 171. See Education law 7701 (2)(1). “Whereas licensed clinical social workers are authorized to make and render diagnoses and the prognoses which flow from and are intimately related to them, administer and interpret tests and measures of psycho social functioning ( so called psycho diagnostic testing…), develop and implement assessment-based treatment plans and provide all forms of psychotherapy; licensed master social workers are only permitted to perform psycho social assessments and evaluations, and may not make or render diagnoses or prognoses , and may administer but not interpret tests and measures of psycho social functioning.” See Education Law §§7701 1(a) and 2(a). 12 Misc 3d at 172-74. A licensed master social worker may render the clinical functions and perform the clinical functions when then do so under the supervision of a licensed clinical social worker. Education Law §7701(d); 8 NYCRR 74.6 n 25.

It is clear that Grinsberg only possesses a master social worker license and hence is not qualified in this state to either make or render diagnoses or prognosis or interpret tests and measures of psycho social functioning. Hence, he does not possess the licensure or expertise which would qualify him to testify as an expert as to the merit or medical necessity of the five psychological tests at issue in general or how these tests pertained to the assignor. Furthermore, Grinsberg presented no testimony that he actually worked under the supervision of a licensed clinical social worker. In fact, it appears that his social worker license was irrelevant to his main job duty at Five – Boro – to supervise clinical paper work and process the claims.”

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.

Evidentiary Issues in New York Litigation

The rules of evidence determine what information a court or arbitrator may consider in deciding a case. In New York no-fault and personal injury practice, evidentiary issues arise constantly — from the admissibility of business records and medical reports to the foundation requirements for expert testimony and the application of hearsay exceptions. These articles examine how New York courts apply evidentiary rules in insurance and injury litigation, with practical guidance for building admissible evidence at every stage of a case.

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.

J.T. you are the go to guy with arcane questions involving law. Can I sue Dr. Grinsberg for medical malpractice even if he didn’t really treat me. Could we use a zone of danger theory. I, as a person sufferring from mental issues, came within the zone of danger of Dr. Grinsberg who allegedly treats people with mental issues. Specifically I could have picked him as my doctor. Even more the report of his incompetence and other related incompetence left me in worse mental shape. Rogak will you rep me. What about a class action.

It’s Kahn from the “Wrath of Kahn” you classless idiots. “Que classe de idiotes” as my Spanish neighbor used to say to me when I was growing up — translated “what class of idiot” — I think he was referring to me when he said it because it was usually in a severe tone. There is a tie in. The man was a psychiatrist who treated various patients that ended up becoming serial killers and the “dart man” — the guy that would wander Manhattan throwing darts into the buttocks of women whom he felt were wearing skirts that were too tight and revealing.

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.
