Understanding Prima Facie Cases in No-Fault Insurance Law

The concept of a “prima facie case” serves as a fundamental building block in no-fault insurance litigation. Essentially, a prima facie case represents the minimum evidence a plaintiff must present to shift the burden of proof to the defendant. In the context of no-fault insurance disputes, establishing this threshold typically involves demonstrating that proper procedures were followed and statutory requirements were met.

The Appellate Term’s decision in Jesa Med. Supply, Inc. v Republic W. Ins. Co. provides valuable insight into what constitutes sufficient evidence for a prima facie case. This ruling clarifies the evidentiary standards that medical providers and other no-fault claimants must meet when seeking summary judgment against insurance carriers who fail to timely respond to claims.

Understanding these standards is crucial for practitioners, as establishing a prima facie case can be the difference between success and failure in no-fault litigation. The burden-shifting nature of prima facie cases means that once properly established, the insurance company must present evidence to create a genuine dispute of material fact.

Prima facie proof in no-fault cases typically consists of three core elements: evidence that medical services or supplies were provided, proof that claims were properly submitted to the insurer, and demonstration that the insurer failed to pay or deny within the statutory timeframe. When plaintiffs establish these elements through competent evidence, courts will grant summary judgment unless insurers raise triable issues of fact through their opposition papers.

Case Background

Jesa Medical Supply, Inc. provided medical equipment to an injured patient and submitted claims to Republic Western Insurance Company for payment under New York’s no-fault system. When the insurer failed to pay or deny the claims within the required 30-day period, Jesa Medical moved for summary judgment.

In support of its motion, the medical supplier submitted an affidavit from a company representative who averred that she had personally mailed the claim to the defendant and that the insurer did not deny the claim within 30 days of submission. Republic Western opposed the motion, but the court needed to determine whether Jesa Medical’s showing was sufficient to establish prima facie entitlement to judgment.

Jason Tenenbaum’s Analysis

Jesa Med. Supply, Inc. v Republic W. Ins. Co., 2011 NY Slip Op 51127(U)(App. Term 2d Dept. 2011)

A universal definition of a prima facie case.

“The affidavit also established that the claim was mailed to defendant, as the affiant averred that she had personally mailed the claim, and that defendant did not deny the claim within 30 days. Consequently, plaintiff established its prima facie entitlement to summary judgment (see Westchester Med. Ctr. v Nationwide Mut. Ins. Co., 78 AD3d 1168 ), and the burden shifted to defendant to raise a triable issue of fact”

The Jesa Medical Supply decision provides a clear, concise definition of what constitutes prima facie proof in no-fault insurance litigation. By breaking down the required elements—proof of service provision, claim submission, and insurer’s failure to timely respond—the court gives practitioners a roadmap for establishing entitlement to summary judgment.

The decision emphasizes the importance of personal knowledge in establishing mailing. The affiant didn’t simply state that claims are routinely mailed according to office procedure; she averred that she personally mailed this specific claim. This personal involvement distinguishes reliable proof from generic assertions about office practices. While testimony about standard mailing procedures can suffice in some contexts, personal knowledge of actual mailing provides the strongest foundation for prima facie proof.

The ruling also illustrates burden-shifting in summary judgment practice. Once plaintiffs establish prima facie cases, defendants cannot defeat summary judgment through speculation or conclusory denials. Defendants must present admissible evidence raising genuine disputes about material facts. This framework ensures that summary judgment serves its intended function: resolving cases where no real factual disputes exist, thereby conserving judicial resources and providing prompt relief to deserving parties.

Practical Implications

For healthcare providers and plaintiffs’ attorneys, Jesa Medical Supply offers a template for establishing prima facie cases. Affidavits supporting summary judgment motions should include personal knowledge statements about claim mailing, not just generic assertions about office procedures. The affiant should state that they personally mailed the specific claim at issue, when it was mailed, and to what address. These details demonstrate personal knowledge and make the affidavit more credible and harder to challenge.

Providers should also document the insurer’s failure to timely respond. The affidavit should state that no denial was received within 30 days (or whatever timeframe applies). If possible, providers should attach correspondence showing when claims were submitted and note the absence of timely denials. This documentary support strengthens prima facie showings and makes it more difficult for insurers to claim they actually sent denials that providers simply didn’t receive.

For insurance carriers and defense counsel, Jesa Medical Supply highlights the importance of timely claim processing. When carriers fail to pay or deny within statutory timeframes, they create exposure to summary judgment. Even if carriers ultimately have valid defenses to payment, failing to assert those defenses within the regulatory periods can result in automatic liability. Defense counsel should also scrutinize plaintiffs’ prima facie showings for gaps or deficiencies, such as lack of personal knowledge about mailing or insufficient proof of non-receipt of timely denials.

Key Takeaway

The Jesa Med. Supply decision demonstrates that a prima facie case in no-fault insurance requires clear evidence of proper claim submission and the insurer’s failure to timely respond. When these elements are established through proper affidavits, the burden shifts to the insurance company to demonstrate why the claim should not be paid. This framework provides predictability for practitioners handling no-fault cases.

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 does 'prima facie case' mean in no-fault litigation?

In no-fault litigation, the provider or claimant bears the initial burden of establishing a prima facie case by submitting proof of the claim — including evidence that the services were provided, the claim was timely submitted, and the amount billed is correct. Once the prima facie case is established, the burden shifts to the insurer to demonstrate a valid defense, such as medical necessity denial, lack of coverage, or failure to appear for an EUO or IME.

Understanding New York Prima Facie case Law

New York has a unique legal landscape that affects how prima facie case 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 prima facie case 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.
