Key Takeaways
- This post is a tribute to Norman Dachs, Esq., a pioneer of third-party personal injury practice who later served as a no-fault master arbitrator.
- His master arbitration decisions were marked by intellectual rigor — he pushed the bounds of the review standard rather than rubber-stamping lower awards.
- The author’s respect survived a fresh loss: Dachs had just reversed one of the author’s lower arbitration wins, sending the dispute to Supreme Court on a petition.
- The post argues the no-fault system needs more arbitrators of his caliber — engaged reviewers, not passive affirmers.
The Tribute
It is with sadness that I learned about the passing of Norman Dachs.
I never had the pleasure of meeting Norman Dachs, Esq. He was a pioneer in the third-party personal injury realm, but I did not get heavily involved in that area of work until I started my practice in 2010 and never knew him in that vain. Mr. Dachs became a master arbitrator a few years ago. My review of the hundreds of decisions he wrote showed a very intellectual viewpoint. There is no other master arbitrator who would push the bounds of Petrosky as Mr. Dachs. In fact, writing a brief to him was many times more intellectually thrilling than the rote Appellate Term, Second Department responses that I am stuck writing.
For purposes of full disclosure, I would note that I was cursing his name last week as he reversed a lower arbitration victory of mine, forcing a trip to Supreme Court on a Petition. I just filed the Petition today. While I disagreed with him, I appreciated his vigor and the fact that he was not a rubber stamp to the awards of the AAA arbitrators. We need more Norman Dachs’ in the no-fault system. A good hire on the part of DFS and a true attorney. I will miss Master Dachs.

What a Master Arbitrator Does in the No-Fault System
For readers outside the no-fault bar, the role Mr. Dachs held deserves some explanation. Most first-party no-fault disputes between medical providers and insurance carriers in New York are resolved in arbitration administered by the American Arbitration Association under the Department of Financial Services’ regulations. When a party loses before the AAA arbitrator, the regulation provides a built-in appellate layer: review by a master arbitrator under 11 NYCRR 65-4.10.
Master arbitration review is deliberately narrow. The master arbitrator does not retry the case or reweigh the medical evidence; the recognized grounds focus on whether the award was arbitrary, capricious, irrational, or incorrect as a matter of law. The “Petrosky” referenced in the tribute is the case law shorthand for the limits of that review — the line between correcting legal error, which a master arbitrator may do, and second-guessing factual findings, which he may not.
That narrowness is precisely why Mr. Dachs stood out. A master arbitrator who treats the review standard as a formality affirms everything and writes little. One who takes the standard seriously — who probes whether the lower award actually applied the law correctly — makes the second tier meaningful. The tribute’s point is that Dachs did the latter, hundreds of times over, and that briefing to him demanded a lawyer’s best work.
The Next Step: Article 75 Review in Supreme Court
The tribute also captures, in passing, what happens after a master arbitration award: the losing party’s remedy is a petition to Supreme Court under CPLR Article 75 to vacate or confirm the award. Judicial review at that stage is narrower still — courts ask whether the master arbitrator exceeded his power or whether the award lacks a rational basis, not whether the court would have decided the dispute differently.
That layered structure — AAA arbitrator, master arbitrator, Article 75 petition — is the procedural skeleton of New York no-fault dispute resolution. It is designed to be faster and cheaper than plenary litigation, and it works only as well as the people occupying each tier. The author’s willingness to file an Article 75 petition against a Dachs reversal, while simultaneously praising the man’s rigor, says something about both the system and the arbitrator.
Why This Tribute Still Resonates
More than a decade later, the core complaint embedded in this post has not aged: the difference between an engaged adjudicator and a rubber stamp is the difference between a dispute-resolution system that develops the law and one that merely clears dockets. Practitioners who appear regularly in no-fault arbitration — on either the provider or carrier side — know that a thoughtful master arbitrator disciplines the entire tier below: lower arbitrators write better awards when they know someone upstairs is actually reading them.
The same dynamic plays out in the courts, where issues like priority of payment and forced arbitration continue to shape where and how these disputes get heard. The forum changes; the need for rigorous, intellectually honest adjudicators does not.

Legal Update (February 2026): Since this tribute was published in 2014, there have been significant changes to New York’s no-fault arbitration framework and master arbitrator procedures. The Department of Financial Services has implemented various procedural and substantive modifications to the arbitration process, and practitioners should verify current arbitration rules and master arbitrator authority under the existing regulatory structure.
Frequently Asked Questions
What is a master arbitrator in New York no-fault cases?
A master arbitrator is the appellate tier within no-fault arbitration under 11 NYCRR 65-4.10. After an AAA arbitrator issues an award in a dispute between a medical provider and an insurer, either party may seek master arbitration review, which is limited to whether the award was arbitrary, capricious, irrational, or incorrect as a matter of law.
Can a master arbitration award be appealed to court?
Yes. The losing party may petition Supreme Court under CPLR Article 75 to vacate the master arbitration award. Judicial review at that stage is narrow — the court examines whether the master arbitrator exceeded his or her authority or whether the award lacks a rational basis, not whether the court agrees with the result.
Legal Context
Why This Matters for Your Case
New York's no-fault insurance system, established under Insurance Law Article 51, is one of the most complex insurance frameworks in the country. Every motorist must carry Personal Injury Protection coverage that pays medical expenses and lost wages regardless of fault, up to $50,000 per person.
But insurers routinely deny valid claims using peer reviews, EUO scheduling tactics, fee schedule reductions, and coverage defenses. The Law Office of Jason Tenenbaum has handled over 100,000 no-fault cases since 2002 — from initial claim submissions through arbitration before the American Arbitration Association, trials in Civil Court and Supreme Court, and appeals to the Appellate Term and Appellate Division. Jason Tenenbaum is one of the few attorneys in the state who both writes his own appellate briefs and tries his own cases.
His 2,353+ published legal articles on no-fault practice are cited by attorneys throughout New York. Whether you are dealing with a medical necessity denial, an EUO no-show defense, a fee schedule dispute, or a coverage question, this article provides the kind of detailed case-law analysis that helps practitioners and claimants understand exactly where the law stands.
About This Topic
New York No-Fault Insurance Law
New York's no-fault insurance system requires every driver to carry Personal Injury Protection (PIP) coverage that pays medical expenses and lost wages regardless of who caused the accident. But insurers routinely deny, delay, and underpay valid claims — using peer reviews, IME no-shows, and fee schedule defenses to avoid paying providers and injured claimants. Attorney Jason Tenenbaum has litigated thousands of no-fault arbitrations and court cases since 2002.

New York law varies by jurisdiction — court decisions in one Appellate Division department may not be followed in another, and local court rules in Nassau County Supreme Court differ from those in Suffolk County Supreme Court, Kings County Civil Court, or Queens County Supreme Court. The Appellate Division, Second Department (which covers Long Island, Brooklyn, Queens, and Staten Island) and the Appellate Term (which hears appeals from lower courts) each have distinct procedural requirements and precedents that affect litigation strategy.
