Establishing causation is one of the most critical elements in New York personal injury litigation. Plaintiffs must prove not only that they suffered injuries, but that those injuries were directly caused by the defendant’s actions. This burden becomes particularly challenging when defendants present expert testimony questioning the connection between the accident and claimed injuries.

The Streety v Toure case from New York’s First Department demonstrates how courts weigh competing expert opinions on causation. This decision illustrates the strategic importance of comprehensive medical documentation and expert testimony in overcoming defense challenges to injury causation—issues that frequently arise in New York No-Fault Insurance Law cases where proving the extent and origin of injuries is essential for recovery.

Jason Tenenbaum’s Analysis:

Streety v Toure, 2019 NY Slip Op 04487 (1st Dept. 2019)

(1) “The report of defendants’ expert emergency medicine physician is sufficient to establish their prima facie burden on the issue of causation insofar as the physician opined that the record of plaintiff’s examination in the emergency room showed findings inconsistent with his claimed injuries.”

(2) ” In opposition, plaintiff raised an issue of fact as to serious injury of a permanent nature through the submission of his pertinent medical records documenting complaints of pain and treatment to the affected body parts within days of the accident (see Perl v Meher, 18 NY3d 208, 217-218 ) as well as the affirmed report of his treating orthopedic surgeon, who reviewed plaintiff’s medical history, his own treatment of plaintiff, and plaintiff’s MRIs, and who recounted his direct observations of plaintiff’s injuries during surgery and opined that they were causally related to the accident”

So the surgeon wrote an affidavit that accounted for the history, the operative report and opined visually a causally related injury consistent with an MVA. That takes the case to trial.

Key Takeaway

Courts recognize that treating physicians who conduct surgery and directly observe injuries have significant credibility in establishing causation. When a surgeon provides comprehensive testimony reviewing medical history, operative findings, and imaging studies while opining on causal relationship, this creates sufficient factual issues to survive summary judgment motions challenging injury causation.

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 is an Independent Medical Examination (IME)?

An IME is a medical examination conducted by a doctor chosen by the insurance company to evaluate the claimant's injuries and treatment. In no-fault cases, insurers use IMEs to determine whether ongoing treatment is medically necessary, whether the injuries are causally related to the accident, and whether the claimant has reached maximum medical improvement. The results of an IME can form the basis for a claim denial or cut-off of benefits.

Can I refuse to attend an IME?

No. Under New York's no-fault regulations, attending an IME when properly scheduled is a condition precedent to receiving benefits. However, the insurer must follow specific scheduling procedures — including providing reasonable notice and accommodating certain scheduling conflicts. If the insurer fails to properly schedule the IME or you have a legitimate reason for missing it, the resulting denial may be challenged.

How should I prepare for an Independent Medical Examination?

Be honest and thorough when describing your symptoms, limitations, and treatment history. Arrive on time with photo ID and be prepared for a physical examination that may test your range of motion and functional abilities. The IME doctor works for the insurance company and may spend limited time with you, so clearly communicate your ongoing symptoms. Your attorney can advise you on what to expect and review the IME report for accuracy afterward.

What is maximum medical improvement (MMI) in no-fault cases?

Maximum medical improvement (MMI) means the point at which your condition has stabilized and further treatment is unlikely to produce significant improvement. When an IME doctor determines you have reached MMI, the insurer may cut off further no-fault benefits. However, reaching MMI does not necessarily mean you have fully recovered — you may still have permanent limitations. Your treating physician can dispute the MMI finding through a detailed rebuttal affirmation.

Can I challenge an IME doctor's findings in my no-fault case?

Yes. If an IME results in a denial or cut-off of benefits, your treating physician can submit a sworn affirmation rebutting the IME findings point by point. The rebuttal should reference specific clinical findings, objective test results, and range-of-motion measurements that contradict the IME conclusions. At arbitration or trial, the fact-finder weighs both the IME report and the treating physician's opinion. An experienced no-fault attorney can identify weaknesses in the IME report.

Understanding New York IME issues Law

New York has a unique legal landscape that affects how ime issues 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 ime issues 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.

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.
